  Embodiments of a lighting control device, a program, and a lighting control system according to the present invention will be described below in detail with reference to the accompanying drawings.

  The lighting control apparatus according to the present embodiment controls a plurality of lighting devices distributed and arranged in the control target area. In the present embodiment, the control target area is considered as being divided into a plurality of small areas respectively corresponding to the positions of the plurality of illumination devices arranged in a distributed manner. Then, a first weight according to the position of the small area and a second weight according to the position of the person in the control target area are given to each small area, and the small areas are distributed in the control target area. The dimming levels of the plurality of lighting devices are controlled using the first weight and the second weight assigned to the corresponding small area. This makes it possible to finely control the dimming levels of a plurality of lighting devices distributed and arranged in the control target area, to realize power saving, and to reduce the sense of discomfort given to people in the control target area.

  Patent Document 1 divides an LED lighting device whose dimming level is controlled by PWM control into a plurality of independently controllable LED groups, and controls the dimming level for each LED group, thereby dimming the entire space. It proposes a technique to control arbitrarily. For example, in Patent Document 1, the illuminance on the desk on the window side of the room and the illuminance on the desk on the indoor side are measured by the illuminance sensor, and the sum of the external light and the light of the LED lighting device is equalized on the desk for each LED group. The dimming level of each LED group is controlled so that the position of a person in a large room is detected by a human sensor, and the darker the more the person is concentrically around the position where the person is. It is described that the level is controlled.

  However, in the technique described in Patent Document 1, since the dimming level of the LED group is controlled by feeding back the detection value of the illuminance sensor or the human sensor, not only the control becomes complicated, but also the control is limited. There is. On the other hand, in the present embodiment, the control target area is divided into a plurality of small areas, and each small area is assigned using the first weight and the second weight assigned to the plurality of small areas. Since the dimming level of the lighting device corresponding to the area is controlled, dimming control corresponding to various needs can be easily performed. For example, the first weight is used to reduce the dimming level of the lighting device corresponding to the small area where the external light enters, or to adjust the lighting device corresponding to the small area where the human frequently passes. It is possible to perform dimming control that reflects the characteristics of the position of the small area within the control target area, such as increasing the light level. In addition, for example, the second weight is used not only to increase the dimming level of the lighting device corresponding to the small area where the person is present, but also to appropriately adjust the dimming level of the lighting apparatus corresponding to the small area where the human is not present. It is also possible to control the dimming level of the lighting device corresponding to a small area where a human is present in consideration of the operation status in addition to the human position.

  That is, the LED lighting device 500 is remotely controlled by the control server device 200 for the dimming level. That is, as an illumination system that illuminates the room that is the control target area, the LED illumination device 500 with a dimming function is used in consideration of low power consumption, and the dimming level of the LED illumination device 500 is Control is performed by the control server device 200 by a wireless control method based on Wi-Fi.

That is, the tap 600 is provided with an on / off switch that can be remotely controlled individually for each tap opening. The on / off control is performed by the control server device 200 using a Wi-Fi wireless control scheme. The number of tap openings included in one tap 600 can be any number, but as an example, a structure in which one tap is constituted by four tap openings can be used.

  As shown in FIG. 6, one tap 600 is installed on each desk. The tap 600 can be connected to an electrical device (not shown), specifically, a desktop PC, a display device, a notebook PC, a printer device, and chargers.

  In the present embodiment, the power source of a display device, which is a device in which a direct relationship with a person is important, is connected to the tap opening of the tap 600. The display device is a device that can be controlled by turning on / off the power supplied to the tap port by the control server device 200.

  When a desktop PC main body or a printer device is connected to the tap 600, the control server device 200 cannot control the power supplied to the tap port on / off due to the configuration of the device. For this reason, for desktop PCs, control software can be controlled by installing control software that can shift to the power saving mode or shutdown via the network, and return from the power saving mode or shutdown state.

  FIG. 7 is a block diagram showing a functional configuration of the positioning server device 100. As shown in FIG. 7, the positioning server device 100 mainly includes a communication unit 101, a position specifying unit 102, an operation state detection unit 103, a correction unit 104, and a storage unit 110.

  The storage unit 110 is a storage medium such as a hard disk drive (HDD) or a memory, and stores various information necessary for processing of the positioning server device 100 such as indoor map data that is a control target area.

  The communication unit 101 detects the acceleration sensor, the angular velocity sensor, and the geomagnetic sensor mounted on the smartphone 300 at regular intervals, or the acceleration sensor, the angular velocity sensor, and the geomagnetic sensor of the sensor group 301 separate from the smartphone 300. Receive data. That is, the communication unit 101 receives an acceleration vector from the acceleration sensor, receives an angular velocity vector from the angular velocity sensor, and receives a magnetic orientation vector from the geomagnetic sensor.

  In addition, the communication unit 101 receives a captured image from the monitoring camera 400. Further, the communication unit 101 transmits an operation status such as an absolute position of an employee, which will be described later, and a direction, posture, and the like to the control server device 200.

  The position specifying unit 102 analyzes the received detection data and specifies the absolute position of the employee in the room with the accuracy of the human shoulder width or stride. Details of the method for specifying the absolute position of the employee by the position specifying unit 102 will be described later.

  The operation state detection unit 103 analyzes the received detection data and detects the operation state of the employee. In the present embodiment, the operation state detection unit 103 detects whether the employee is in a stationary state or a walking state as the operation state. In addition, when the operation status is stationary, the operation status detection unit 103 operates based on the detection data to determine whether the employee's direction and the employee's posture with respect to the device in the control target area are standing or sitting. Detect the situation.

  That is, when it is detected from the captured image from the monitoring camera 400 that the employee has entered the room through the door, the operation state detection unit 103 detects the acceleration sensor, the angular velocity sensor, and the like of the smartphone 300 attached to the employee who has entered the room. Using the time series data of the acceleration vector and the angular velocity vector among the detection data sequentially received from the acceleration sensor, the angular velocity sensor, and the geomagnetic sensor of the sensor group 301 separate from the geomagnetic sensor or the smartphone 300, the employee's It is sequentially determined whether the operation state is a walking state or a stationary state. Here, the method of determining whether the employee's motion state is the walking state using the acceleration vector and the angular velocity vector can be realized by, for example, processing by a dead reckoning device disclosed in Japanese Patent No. 4243684. Then, when it is determined that the person is not in a walking state by this method, the operation state detection unit 103 can determine that the person is in a stationary state.

  More specifically, the operation state detection unit 103 can detect a human operation state as follows, similarly to the processing by the dead reckoning device disclosed in Japanese Patent No. 4243684.

  That is, the operation state detection unit 103 obtains a gravitational acceleration vector from the acceleration vector received from the acceleration sensor and the angular velocity vector received from the angular velocity sensor, subtracts the gravitational acceleration vector from the acceleration vector, and removes the vertical acceleration. Obtain time-series data of residual acceleration components. Then, the motion state detection unit 103 performs principal component analysis on the time-series data of the residual acceleration component to obtain the traveling direction of the walking motion. Furthermore, the motion state detection unit 103 searches for a pair of peak and valley peaks of the acceleration component in the vertical direction, and searches for a pair of valley peak and peak of the acceleration component in the traveling direction. Then, the operation state detection unit 103 calculates the gradient of the acceleration component in the traveling direction.

  Furthermore, the operation state detection unit 103 determines whether or not the gradient of the acceleration component in the traveling direction is equal to or greater than a predetermined value at the detection time of the valley peak at which the vertical acceleration component changes from the peak to the peak. And when it is more than a predetermined value, it determines with an operating condition of an employee being a walking state.

  On the other hand, in the above processing, a peak-to-valley peak pair in the vertical acceleration component is not searched, or a trough peak-to-peak peak pair in the traveling acceleration component is not searched, or a vertical acceleration is detected. When the gradient of the acceleration component in the traveling direction is less than a predetermined value at the time of detection of the valley peak at which the component changes from the peak to the valley peak, the movement status detection unit 103 indicates that the movement status of the employee is stationary. It is determined that it is in a state.

  When it is determined that the employee is in a stationary state, the position specifying unit 102 uses the acceleration vector, the angular velocity vector, and the magnetic orientation vector as a reference position, and determines that the employee is in a stationary state from the reference position. A relative movement vector to the determined position is obtained. Here, as a calculation method of the relative movement vector using the acceleration vector, the angular velocity vector, and the magnetic azimuth vector, for example, a method disclosed in the processing of the dead reckoning device disclosed in Japanese Patent Application Laid-Open No. 2011-47950 can be used.

  More specifically, the position specifying unit 102 can obtain the relative movement vector as follows, similarly to the processing of the dead reckoning device disclosed in Japanese Patent Application Laid-Open No. 2011-47950.

  That is, the position specifying unit 102 obtains a gravity azimuth vector from the acceleration vector received from the acceleration sensor and the angular velocity vector received from the angular velocity sensor, and from the gravity azimuth vector and the magnetic azimuth vector received from the angular velocity vector or the geomagnetic sensor, The attitude angle is calculated as the moving direction. The position specifying unit 102 obtains a gravitational acceleration vector from the acceleration vector and the angular velocity vector, and calculates an acceleration vector generated by the walking motion from the gravitational acceleration vector and the acceleration vector. Then, the position specifying unit 102 analyzes and detects the walking motion from the gravitational acceleration vector and the acceleration vector generated by the walking motion, and determines the magnitude of the walking motion based on the detection result. And the acceleration vector generated by the walking motion, and the measurement result is used as a stride. Then, the position specifying unit 102 obtains a relative movement vector from the reference position by integrating the movement direction and the stride thus obtained. In other words, the position of the person in charge is detected in real time with an accuracy of human stride or shoulder width, for example, approximately 60 cm or less (more specifically, approximately 40 cm or less).

  When the relative movement vector is calculated in this way, the position specifying unit 102 determines the absolute position after the movement of the employee from the relative movement vector from the door and the indoor map data stored in the storage unit 110. Identify.

  Thereby, the position specifying unit 102 can specify up to which desk the employee is placed in the room, and as a result, the shoulder width of the person, for example, approximately 60 cm or less (more specifically, approximately The position of the employee can be specified with an accuracy of about 40 cm or less.

  The higher the positional accuracy, the better. For example, assuming a scene in which two or more people are having a conversation, it is rare that they talk in contact with each other, and they are separated by a certain distance. Therefore, when considering accuracy, in this embodiment, the accuracy corresponding to the length from the waist to the knee is used as the accuracy appropriate for the accuracy equivalent to the human shoulder width or stride, whether standing or sitting.

  According to the anthropometric data published by the Ministry of Health, Labor and Welfare (Makiko Kawachi, Masaaki Mochimaru, Hiroshi Iwasawa, Seiji Mitani (2000): Japanese Human Body Size Database 1997-98, Ministry of International Trade and Industry, Industrial Technology Institute and JIS Center) The data (shoulder width) corresponding to the shoulder width of adolescents and elderly men and women is about 35 cm (34.8 cm) for the elderly women with the lowest average value, and about 40 cm (39.7 cm) for the highest adolescent men It has become. Similarly, the difference between the length from the waist to the knee (pubic bone joint upper edge height−femoral outer epicondyle height) is about 34 cm to about 38 cm. On the other hand, the stride when a human moves is 95 steps when walking 50 m, and is about 53 cm (50 ÷ 95 × 10) from now on, and the position detection method according to the present embodiment can have an accuracy equivalent to the stride. . Therefore, from the above data, the present embodiment is configured assuming that an accuracy of 60 cm or less, preferably 40 cm or less is appropriate. These data serve as a standard for considering accuracy, but are based on the Japanese and are not limited to these values.

  In addition, when the employee's absolute position is specified and the employee is stationary at the seat in front of the desk, the operation status detection unit 103 determines the employee's position based on the orientation of the magnetic orientation vector received from the geomagnetic sensor. A direction (orientation) with respect to the display device is determined. In addition, when the employee is stationary at the seat in front of the desk, the operation state detection unit 103 determines the posture of the employee, that is, whether the employee is standing or sitting from the vertical acceleration component of the acceleration vector. To do.

  Here, as in the dead reckoning device disclosed in, for example, Japanese Patent No. 4243684, the determination as to the standing state or the sitting state is based on the acceleration vector received from the acceleration sensor and the angular velocity vector received from the angular velocity sensor. Thus, the acceleration component in the vertical direction can be obtained. And the operation condition detection part 103 can obtain | require the peak of the peak and trough of the acceleration component of a perpendicular direction similarly to the dead reckoning apparatus currently disclosed by patent 4243684, for example.

  FIG. 8 is a diagram illustrating waveforms of acceleration components in the vertical direction when the sitting operation and the standing operation are performed. As shown in FIG. 8, in the case of the seating operation, the interval from the peak of the peak of the acceleration component in the vertical direction to the peak of the valley is about 0.5 seconds. On the other hand, in the standing motion, the interval from the peak of the vertical acceleration component to the peak of the peak is about 0.5 seconds. For this reason, the operation state detection unit 103 determines whether the employee is in a sitting state or a standing state based on the peak interval. That is, when the interval from the peak of the peak of the acceleration component in the vertical direction to the peak of the valley is within a predetermined range from 0.5 seconds, the operation state detection unit 103 is in the seated state. Is determined. Further, when the interval from the peak of the vertical acceleration component peak to the peak of the mountain is within a predetermined range from 0.5 seconds, the operation state detection unit 103 is in an upright state. Is determined.

  As described above, when the operation state detection unit 103 determines whether the employee's operation state is the standing state or the seating state, the position in the height direction of the employee is approximately 50 cm or less (more specifically, approximately 40 cm). It means that it was detected with the following accuracy.

  Further, as in the example shown in FIG. 3, a smartphone 300 equipped with information devices for detecting human motion such as an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor is worn on the waist, and further, the acceleration sensor, the angular velocity sensor, and the geomagnetism are mounted. When a small headset-type sensor group 301 including sensors is mounted on the head, the operation state detection unit 103 can further detect the posture and movement of the employee as described below.

  FIG. 9 is a diagram showing waveforms of angular velocity components in the horizontal direction when the squatting operation and the standing operation are performed. From the acceleration data from the acceleration sensor, waveforms similar to those of the seating motion and the standing motion shown in FIG. 8 are detected, but it is difficult to discriminate the squatting motion and the standing motion only from the acceleration data.

  For this reason, the motion state detection unit 103 uses the above-described method for discriminating between the sitting motion and the standing motion based on the waveform of FIG. 8, and the temporal change in the angular velocity data in the horizontal direction received from the angular velocity sensor becomes the waveform of FIG. By judging whether or not they match, a squatting action and a standing action are discriminated.

  Specifically, the operation state detection unit 103 first has an interval from the peak of the vertical acceleration component to the peak of the valley based on the acceleration vector received from the acceleration sensor within a predetermined range from 0.5 seconds. Determine whether or not.

  When the interval from the peak of the peak of the acceleration component in the vertical direction to the peak of the valley is within a predetermined range from 0.5 seconds, the motion state detection unit 103 detects the horizontal direction of the angular velocity vector received from the angular velocity sensor. As shown in the waveform of FIG. 9, the angular velocity component of gradually increases from 0, then reaches a peak of the mountain with a rapid increase, gradually decreases from the peak of the mountain, then gradually returns to 0, and the time between Is about 2 seconds, it is determined that the employee's action is a squatting action.

  In addition, the operation state detection unit 103 determines whether or not the interval from the peak of the valley of the acceleration component in the vertical direction to the peak of the peak is within a predetermined range from 0.5 seconds. When the interval from the peak of the valley of the acceleration component in the vertical direction to the peak of the mountain is within a predetermined range from 0.5 seconds, the motion state detection unit 103 performs the horizontal direction of the angular velocity vector received from the angular velocity sensor. When the angular velocity component of the peak reaches the valley peak stepwise from 0, gradually returns to 0 from the valley peak, and the time between them is about 1.5 seconds, as shown in the waveform of FIG. It is determined that the employee's movement is a standing movement.

  As the angular velocity vector used in the determination of the squatting motion and the standing motion in the motion state detection unit 103 as described above, it is preferable to use an angular velocity vector received from an angular velocity sensor mounted on the head. This is because the angular velocity component in the horizontal direction based on the angular velocity vector from the angular velocity sensor worn on the head shows the waveform shown in FIG.

  FIG. 10 is a diagram illustrating a waveform of the angular velocity component in the vertical direction when the employee performs an operation of changing the direction by approximately 90 degrees in a stationary state. If the angular velocity component in the vertical direction is positive, the direction is changed to the right side, and if it is negative, the direction is changed to the left side.

  The operation state detection unit 103 gradually changes the angular velocity component in the vertical direction of the angular velocity vector received from the angular velocity sensor from 0 to gradually reaching the peak of the mountain as shown in FIG. When it returns and the time between these is about 3 seconds, it determines with the operation | movement changing a direction to the right.

  Further, the operation state detection unit 103 gradually returns to 0 after the time-dependent change in the angular velocity component in the vertical direction reaches the peak of the valley gradually from 0 as shown in the waveform of FIG. Is about 1.5 seconds, it is determined that the direction changes to the left.

  The motion state detection unit 103 is similar to the waveform of FIG. 10 according to the above-described determination in terms of the vertical angular velocity component of the angular velocity vector received from both the angular velocity sensor of the head and the angular velocity sensor of the hip smartphone 300. When the change over time is indicated, it is determined that the movement of the whole body changes to the right or left.

  On the other hand, the motion state detection unit 103 shows that the vertical angular velocity component of the angular velocity vector received from the angular velocity sensor of the head shows a temporal change similar to the waveform of FIG. When the angular velocity component in the vertical direction of the angular velocity vector from the angular velocity sensor shows a temporal change that is completely different from the waveform of FIG. 10, it is determined that the direction of the head is changed to the right or left. As such an operation, for example, a posture operation in the case of communicating with an adjacent employee while the employee is sitting can be considered.

  FIG. 11 is a diagram showing the waveform of the angular velocity component in the horizontal direction of the angular velocity vector received from the angular velocity sensor of the head when the line of sight is removed from the display in the sitting state.

  Consider a case where the position specifying unit 102 specifies the absolute position of the employee as being in front of the desk, and the operation state detecting unit 103 detects that the employee in front of the desk is in a sitting state. In such a case, the motion state detection unit 103 gradually increases the angular velocity component in the horizontal direction of the angular velocity vector received from the angular velocity sensor of the employee's head from 0 as shown in the waveform of FIG. When the peak of the valley is reached and then suddenly returns to 0 and the time between them is about 1 second, it is determined that the operation is an operation in which the eyes are removed from the display in the sitting state (upward operation). Further, the operation state detection unit 103 reaches the peak of the mountain while the angular velocity component in the horizontal direction gradually increases from 0 as in the waveform shown in FIG. 11, and then gradually returns to 0. When the time is about 1.5 seconds, it is determined that the operation is to return the line of sight to the display from the state where the line of sight is removed from the display in the sitting state.

  FIG. 12 is a diagram showing the waveform of the angular velocity component in the horizontal direction of the angular velocity vector received from the angular velocity sensor of the head when the line of sight is removed from the display in the sitting state.

  Consider a case where the position specifying unit 102 specifies the absolute position of the employee as being in front of the desk, and the operation state detecting unit 103 detects that the employee in front of the desk is in a sitting state. In such a case, the operation state detection unit 103 causes the angular velocity component in the horizontal direction of the angular velocity vector received from the angular velocity sensor of the employee's head to suddenly start from 0 as shown in the waveform shown in FIG. When it reaches the peak of the mountain and then suddenly returns to 0 and the time between them is about 0.5 seconds, it is determined that the movement is looking down from the display while sitting down. To do.

  Further, the operation state detection unit 103 reaches the peak of the valley while the angular velocity component in the horizontal direction decreases rapidly from 0 as in the waveform shown in FIG. 12, and then suddenly returns to 0. When the time is about 1 second, it is determined that the operation is to return the line of sight to the display from the state where the line of sight is removed from the display in the sitting state.

  As described above, the motion state detection unit 103 is a posture and motion that an office employee can take on a daily basis, that is, walking (standing state), standing (stationary state), sitting on a chair, squatting at work, sitting state Alternatively, it is possible to determine by the above-described method whether the direction (direction) is changed in the standing state, looking up at the heaven in the sitting state or the standing state, whispering in the sitting state or the standing state, and the like.

  In addition, when using the technique of the dead reckoning device of patent 4243684, as disclosed in patent 4243684, the lifting and lowering motion of a human by an elevator is also determined using the acceleration component in the vertical direction. .

  For this reason, in the present embodiment, the operation state detection unit 103 uses the function of the map matching device disclosed in, for example, Japanese Patent Application Laid-Open No. 2009-14713, and displays the vertical acceleration component in a place without an elevator. In the case where the waveform shown in FIG. 8 is detected, it is possible to determine with high accuracy whether the operation is a standing operation or a seating operation, unlike the elevator lifting / lowering operation by the dead reckoning device of Japanese Patent No. 4243684.

  The correction unit 104 corrects the specified absolute position and operation status (direction and posture) based on the captured image from the monitoring camera 400 and the map data stored in the storage unit 110. More specifically, the correction unit 104 determines whether or not the absolute position, direction, and posture of the employee determined as described above are correct by image analysis of the captured image of the monitoring camera 400 or the like, It is determined whether or not the data is correct using the data and the function of the map matching device disclosed in, for example, Japanese Patent Application Laid-Open No. 2009-14713. If it is incorrect, the correction unit 104 corrects the correct absolute position, direction, and orientation obtained from the captured image and the function of the map matching device.

  The correction unit 104 performs correction using not only a captured image from the monitoring camera 400 but also limited means such as short-range wireless and optical communication such as RFID (Radio Frequency IDentification) and Bluetooth (registered trademark). You may comprise as follows.

  In the present embodiment, the same technique as the dead reckoning device disclosed in Japanese Patent No. 4243684 and Japanese Patent Application Laid-Open No. 2011-47950, and the same as the map matching device disclosed in Japanese Patent Application Laid-Open No. 2009-14713 The technology detects the motion state of the employee, the relative movement vector from the reference position, and the posture (whether standing or seated), but the detection method is not limited to these technologies.

  In addition, as a technique capable of detecting a human position, in addition to the method described above performed by the positioning server device 100 based on detection data of an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor, for example, entrance / exit management using an IC card or the like , Human detection by a human sensor, a method using a wireless LAN, a method using an indoor GPS (IMES), a method for processing an image captured by a camera, a method using an active RFID, and visible light communication Methods are known.

  In the entrance / exit management using an IC card or the like, personal identification is possible, but the positioning accuracy is extremely low for the entire management target area. Therefore, although it is possible to know who is in the area, it is not possible to grasp the human activity status in the area.

  Human detection by a human sensor can obtain a positioning accuracy of about 1 to 2 m which is a detection range of the human sensor, but individual identification cannot be performed. In addition, in order to grasp the human activity state in the area, it is necessary to disperse and arrange a large number of human sensors in the area.

  In the method using a wireless LAN, the distance between one wireless LAN terminal possessed by a human and a plurality of LAN access points installed in the area is measured, and the position of the human in the area is determined by the principle of triangulation. Is identified. Although this method enables individual identification, the positioning accuracy is highly dependent on the environment, and the positioning accuracy is generally as low as 3 m or more.

  In the method using indoor GPS, a dedicated transmitter that emits radio waves in the same frequency band as GPS satellites is installed indoors. Send. Then, the signal is received by a receiving terminal possessed by an indoor person, thereby specifying the position of the person inside. Although this method can identify individuals, the positioning accuracy is as low as about 3 to 5 m. In addition, it is necessary to install a dedicated transmitter, which increases the introduction cost.

  Although the method for image processing of the captured image of the camera can obtain a relatively high positioning accuracy of about several tens of centimeters, it is difficult to perform individual identification. For this reason, in the positioning server device 100 of the present embodiment, the captured image of the monitoring camera 400 is used only when the absolute position, direction, and posture of the employee are corrected.

  In the method using active RFID, a person has an RFID tag with a built-in battery, and the position of the person is specified by reading information of the RFID tag with a tag reader. Although this method enables individual identification, the positioning accuracy is highly dependent on the environment, and the positioning accuracy is generally as low as 3 m or more.

  The method using visible light communication enables individual identification and relatively high positioning accuracy of about several tens of centimeters. However, humans cannot be detected in places where the visible light is blocked, and natural light and other Since there are many noise sources and interference sources such as visible light, it is difficult to maintain the stability of detection accuracy.

  In contrast to these techniques, the method performed by the positioning server device 100 according to the present embodiment is capable of individual identification, provides high positioning accuracy equivalent to a human shoulder width or stride, and, in addition, only by the human position. Without being able to detect human operating conditions. Specifically, according to the method performed by the positioning server device 100 according to the present embodiment, the posture and motion that an office employee can take on a daily basis, that is, walking (standing state), standing up as a human operating state. Detect (shut down), sit in a chair, squat when working, change direction (direction) in sitting or standing state, look up to the sky in sitting or standing state, whisper in sitting or standing state, etc. Can do.

  For this reason, in this embodiment, the positioning server device 100 uses the above-described method based on the detection data of the acceleration sensor, the angular velocity sensor, and the geomagnetic sensor of the smartphone 300 and the sensor group 301, and in the office that is the control target area. The absolute position of the employee and the operation status of the employee are detected. However, the method for detecting the position of the employee in the room that is the control target area is not limited to the above-described method performed by the positioning server device 100. For example, one or more of the other methods described above are used. The position of the employee may be detected by a combination, and the position of the employee may be detected by combining one or more of the other methods described above with the above-described method performed by the positioning server device 100. It may be.

  Next, details of the control server device 200 will be described. The control server device 200 has a plurality of LED lighting devices 500, a plurality of taps 600, a plurality of taps installed in the room based on the position and operation status (direction, posture, etc.) of the employee in the room that is the control target area. Each of the air conditioners 700 is remotely controlled via a network.

  FIG. 13 is a block diagram showing a functional configuration of the control server device 200 of the present embodiment. As shown in FIG. 13, the control server device 200 according to the present embodiment mainly includes a communication unit 201, a power consumption management unit 202, a device control unit 210, and a storage unit 220.

  The storage unit 220 is a storage medium such as an HDD or a memory, and each of control target devices (a plurality of LED lighting devices 500, a plurality of taps 600, and a plurality of air conditioners 700) installed in a room that is a control target region. Processing of the control server device 200, such as position data, a reference value (reference level) of a dimming level used when performing dimming control on the LED lighting device 500, a first weighting table, a second weighting table, etc. Various kinds of information necessary for storage are stored.

  The communication unit 201 receives the absolute position and motion information (direction, posture) of the employee from the positioning server device 100. Further, the communication unit 201 receives power consumption from the plurality of LED lighting devices 500, the electric devices connected to the plurality of taps 600, and the plurality of air conditioners 700. In addition, the communication unit 201 transmits a control signal for performing power control to the plurality of LED lighting devices 500, the plurality of taps 600, and the plurality of air conditioners 700.

  The power consumption management unit 202 manages the power consumption received from the plurality of LED lighting devices 500, the electric devices connected to the plurality of taps 600, and the plurality of air conditioners 700.

  The device control unit 210 includes a lighting device control unit 211, an outlet control unit 213, and an air conditioner control unit 215.

  The lighting device control unit 211 controls the LED lighting device 500 based on the absolute position and operation status (direction, posture) of the employee. In particular, in the present embodiment, a room that is a control target area is divided into a plurality of small areas (hereinafter, each small area is simply referred to as an area) corresponding to each of the plurality of LED lighting apparatuses 500, and lighting apparatus control is performed. The unit 211 uses the first weight determined in accordance with the position of each area in the room and the second weight in accordance with the position of the employee in the room, and the LED lighting device 500 corresponding to each area. Control the dimming level.

  That is, the lighting device control unit 211 of the present embodiment does not simply control the LED lighting device 500 so that the position where the employee is present in the room is bright and the position where the employee is not is dark. The lighting device control unit 211 refers to the first weighting table and the second weighting table stored in the storage unit 220 for a plurality of areas corresponding to each of the plurality of LED lighting devices 500 distributed in the room. Then, the first weight and the second weight are given. The first weight is a weight given according to the position of each area in the room, and is a static weight determined by reflecting the characteristics of the area position. The second weight is a weight given according to the position of the employee in the room, and is a dynamic weight that changes from time to time according to a change in the position of the employee. And the lighting equipment control part 211 controls each light control level of the some LED lighting equipment 500 using the 1st weight and 2nd weight provided with respect to the corresponding area, While realizing power saving, a comfortable lighting space that reduces the sense of discomfort given to employees in the room is realized. The details of the dimming control by the lighting device control unit 211 will be described later.

  The outlet control unit 213 controls power on / off of the tap opening of the tap 600 based on the absolute position and operation information (direction, posture) of the employee. More specifically, for example, the outlet control unit 213 indicates that the employee is seated on the display device connected to the tap 600 disposed in the vicinity of the received absolute position, and the direction with respect to the display device is In the case of the front, a control signal for turning on the switch of the tap port to which the display device is connected in the tap 600 is transmitted via the communication unit 201.

  On the other hand, the outlet control unit 213 connects the display device connected to the tap 600 when the employee is standing or the direction toward the display device is rearward. A control signal for turning off the switch at the tapped port is transmitted via the communication unit 201.

  As described above, the power control is performed according to the direction of the employee with respect to the display device. The display device is an important device in the direct relationship with the employee, and the display device is used when the direction is forward. It is because it can be judged. Further, it can be determined that the display device is being used when the posture of the employee is in the sitting state. As described above, in the present embodiment, power control is performed in consideration of actual use of the device, and finer control can be performed compared to the case where power control is simply performed based on the distance from the device. It becomes possible.

  Furthermore, the outlet control unit 213 of the present embodiment performs power control of the desktop PC main body and the display device in conjunction with the employee's personal recognition information. For example, the personal authentication information of the employee is transmitted from the smartphone 300 held by the employee to the positioning server device 100 and transmitted from the positioning server device 100 to the control server device 200. Using this personal authentication information, the control server device 200 can perform power control on a desktop PC main body and display device that are exclusively used by employees.

  The air conditioner control unit 215 controls on / off of the power supply of the air conditioner 700 based on the absolute position of the employee. More specifically, the air conditioner control unit 215 transmits, via the communication unit 201, a control signal for turning on the power of the air conditioner 700 set in the group in which the received seat at the absolute position exists, for example.

  Next, the detection process by the positioning server device 100 of the present embodiment configured as described above will be described. FIG. 14 is a flowchart illustrating a procedure of detection processing performed by the positioning server device 100 according to the present embodiment. The detection process according to the flowchart is executed for each of the plurality of smartphones 300.

  In addition to the detection process according to this flowchart, the positioning server device 100 includes an acceleration sensor, an angular velocity sensor, a geomagnetic sensor, or an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor mounted on the plurality of smartphones 300. Detection data (acceleration vector, angular velocity vector, magnetic direction vector) is received from each sensor at regular intervals, and captured images are received from a plurality of monitoring cameras 400.

  First, whether or not the employee has entered the room that is the control target area is determined based on, for example, a captured image of a door that opens and closes (step S11). When entering the room (step S11: Yes), the operation state detection unit 103 detects the operation state of the employee who has entered the room by the above-described method (step S12). Then, the operation state detection unit 103 determines whether or not the employee's operation state is the walking state (step S13), and repeatedly detects the operation state while the worker is in the walking state (step S13: Yes). .

  On the other hand, when the employee's operation state is not the walking state in step S13 (step S13: No), the operation state detection unit 103 determines that the employee's operation state is the stationary state. And the position specific | specification part 102 calculates a relative movement vector from a door by the above-mentioned method by making a reference | standard position into a door (step S14).

  And the position specific | specification part 102 specifies the absolute position of the employee who became the stationary state with the map data of the room preserve | saved at the memory | storage part 110, and the relative movement vector from a door (step S15). Thereby, the position specifying unit 102 can specify up to which desk the employee is placed in the room, and as a result, the shoulder width of the employee (approximately 60 cm or less, more specifically approximately 40 cm). The position of the employee is specified with the accuracy of the following.

  Next, the operation state detection unit 103 further detects the direction (orientation) of the employee with respect to the display device from the magnetic orientation vector received from the geomagnetic sensor as the operation state of the stationary employee (step S16).

  Next, the operation state detection unit 103 detects the posture, whether the sitting state or the standing state, as the operation state of the employee by the above-described method (step S17). Thereby, the operation state detection unit 103 has detected the position in the height direction of the employee with an accuracy of approximately 50 cm or less (more specifically, approximately 40 cm or less).

  Further, the operation status detection unit 103 is an operation status of the employee, whether it is a squatting operation or a standing operation, an operation for changing the orientation in the sitting state, an operation for returning the direction, an operation for raising the line of sight in the sitting state, or an operation for returning the line of sight. Either an operation of lowering the line of sight or an operation of returning the line of sight in the sitting state may be detected.

  Next, the correction unit 104 determines whether or not correction is necessary for the specified absolute position, detected direction, and posture as described above, and corrects if necessary (step S18).

  Then, the communication unit 101 transmits the absolute position, the detected direction and orientation (if corrected, the corrected absolute position, the detected direction and orientation) to the control server device 200 as detection result data. (Step S19).

  Next, device control processing by the control server device 200 will be described. FIG. 15 is a flowchart illustrating a procedure of device control processing by the outlet control unit 213 and the air conditioner control unit 215 in the device control processing of the present embodiment. In addition, the procedure of the light control with respect to the LED lighting apparatus 500 by the lighting apparatus control part 211 is mentioned later.

  First, the communication unit 201 receives the absolute position, direction, and posture of the employee as detection result data from the positioning server device 100 (step S31). Next, the outlet control unit 213 and the air conditioner control unit 215 of the device control unit 210 specify the control target tap 600 and the air conditioner 700 from the absolute position of the received detection result data (step S32).

  More specifically, the outlet control unit 213 refers to the position data stored in the storage unit 220 and specifies the tap 600 installed near the desk corresponding to the absolute position as a control target. In addition, the air conditioner control unit 215 refers to the position data stored in the storage unit 220 and identifies the air conditioner 700 installed corresponding to a group having a desk corresponding to the absolute position as a control target.

  Next, the air conditioner control unit 215 performs control to turn on the power of the identified air conditioner 700 (step S33).

  Next, the outlet control unit 213 determines whether or not the direction of the received detection result data is forward and whether or not the posture of the detection result data is a seated state (step S34). When the direction is the front and the posture is the seating state (step S34: Yes), the outlet control unit 213 switches the switch of the tap mouth to which the display device is connected in the tap 600 specified in step S32. Control to turn on is performed (step S35).

  On the other hand, when the direction is rearward or the posture is standing in step S34 (step S34: No), the outlet control unit 213 connects the display device at the tap 600 specified in step S32. Control is performed to turn off the switch of the tapped port (step S36).

  The outlet control unit 213 and the air conditioner control unit 215 of the device control unit 210 may be configured to perform control other than the above-described control on each control target device.

  In addition, the operation status of the employee may be a squatting or standing operation, an operation to change the orientation in the sitting state, an operation to return, or an operation to raise the line of sight in the sitting state (an operation to look up) or an operation to return the line of sight. The outlet control unit 213 and the air conditioner control unit 215 of the device control unit 210 may be configured to control each device to be controlled depending on whether the operation is to lower the line of sight (operation to look down) or to return the line of sight. .

  The following examples can be given as examples of each operation, device to be controlled, and control method in such a case. These operations are operations that can occur when an employee is seated in front of a desk. The control target device is a PC or a display device of a PC, a desk lamp, and a tabletop fan corresponding to individual air conditioning. Etc.

  For example, when the employee is at a desk and the detected detection result data determines that the operation of squatting continues for a certain period of time or longer, the switch of the tap port to which the PC power supply is connected is turned off. Thus, the outlet control unit 213 can be configured. In addition, the mode control unit can be configured so that the device control unit 210 is provided with a mode control unit that controls the mode of the device, and the display device of the PC is shifted to the standby mode.

  In addition, when the standing operation is detected from the sitting state and the standing state continues for a certain time or more, the mode control unit is configured to shift the PC to the standby mode, or the power supply of the display device is connected at the same time. The outlet control unit 213 can be configured to turn off the switch of the tapped port.

  The following control is given as an example for the operation of changing the direction. When a change in the orientation of the face or upper body is detected from the state of sitting at the desk, and this state continues for a certain period of time, the situation may be such as talking to another employee in the adjacent seat. If the lighting device such as a PC, a display device, a desk lamp, etc. is set to standby or turned off and the orientation of the employee is returned to the original state, and it is detected that the posture is returned to the original posture, the PC, the display device, The outlet control unit 213 and the mode control unit can be configured to turn on a lighting device such as a desk lamp.

  In addition, when the employee reads a document at a desk, an operation of looking down is performed, and when the employee comes up with an idea or thinks of the idea, an operation of looking up at the ceiling direction can be performed. For this reason, when an operation of looking up or looking down for a certain time or longer is continuously detected, the outlet control unit 213 performs control to shift the PC to the standby mode or to turn off the display device. A mode control unit can be configured. Further, in the case of an operation to look down, the outlet control unit 213 may be configured to perform control without turning off the desk lamp.

  As described above, in the present embodiment, the position of the employee is specified with the accuracy of the shoulder width, the direction and posture of the employee is detected, and the power control of the device is performed. Control becomes possible, and further power saving and energy saving can be realized while maintaining the comfort of the employee and high efficiency of work.

  That is, in this embodiment, not only the employee is detected, but also the equipment that the employee uses exclusively, the lighting equipment, the air conditioner, and the office equipment near the desk on which the employee sits are individually controlled. It is possible to grasp the power consumption of each person at the same time.

  In the prior art, even if the power of buildings, offices, entire factories, and entire offices can be realized so-called `` visualization '', it is unclear how individuals should save power, and the overall target value If the situation is not tight, such as exceeding the power supply amount, the power consumption will not be continually promoted because it is difficult to be aware of power saving, etc., but according to this embodiment, the comfort of employees is maintained. Thus, further power saving can be realized while suppressing a decrease in business efficiency.

  Further, according to the present embodiment, even in automatic device control, power saving can be further improved by performing cooperative control between devices as well as employees and devices.

  Next, dimming control of the LED lighting device 500 performed by the lighting device control unit 211 of the present embodiment will be described in detail with a specific example.

  FIG. 16 is a block diagram in which a portion related to the lighting device control unit 211 of the control server device 200 is extracted from the configuration of the device control system according to the present embodiment. As illustrated in FIG. 16, the lighting device control unit 211 of the control server device 200 includes a weighting unit 211a and a dimming control unit 211b. In addition, the storage unit 220 of the control server device 200 includes a reference level storage unit 221, a first weighting table storage unit 222, and a second weighting table storage unit 223. The LED lighting device 500 that is a subject of dimming control is a device whose dimming level is controlled by PWM (pulse width modulation) control, and includes a PWM control circuit 501 and an LED drive circuit 502. In FIG. 16, for convenience, only one LED lighting device 500 is illustrated, but all of the plurality of LED lighting devices 500 provided in the control target region have the same configuration.

  The reference level storage unit 221 stores a reference level that is a reference value of a dimming level common to the plurality of LED lighting devices 500. As an example, the reference level storage unit 221 stores 90% as a reference level when full lighting is set to 100%. Note that the reference level stored in the reference level storage unit 221 can be changed according to the operation of an employee or an administrator who has authority to manage the device control system of the present embodiment.

  The first weighting table storage unit 222 stores a first weighting table in which a plurality of indoor areas that are control target areas and first weights assigned to the respective areas are described in association with each other.

  FIG. 17 is a diagram illustrating a plurality of areas divided according to the position of the LED lighting device 500 in a room that is a control target area. FIG. 17 is based on the layout of the LED lighting device 500 in the room illustrated in FIG.

  In the example of FIG. 17, nine LED lighting devices 500 (LED lighting devices 500_1 to 500_9) configured with two LED lamps as one set are arranged in a room that is a control target area. In the case of this example, the room that is the control target area includes an area A_1 corresponding to the LED lighting device 500_1, an area A_2 corresponding to the LED lighting device 500_2, an area A_3 corresponding to the LED lighting device 500_3, and an LED lighting device 500_4. Area A_4 corresponding to the LED lighting device 500_5, area A_6 corresponding to the LED lighting device 500_6, area A_7 corresponding to the LED lighting device 500_7, and area A_8 corresponding to the LED lighting device 500_8. And the area A_9 corresponding to the LED lighting device 500_9. That is, each divided area is uniquely associated with the LED lighting device 500 that mainly affects the illuminance of the area. The coordinates of the area corresponding to each LED lighting device 500 are calculated based on the coordinates of each LED lighting device 500, for example. The coordinates of each LED lighting device 500 are stored in the storage unit 220 as the position data described above.

  In the example of FIG. 17, the three areas A_1 to A_3 on the upper side of the drawing are areas facing the hallway outside the room, and in these three areas A_1 to A_3, the illumination light in the hallway is external light. Shall enter. In addition, in area A_1 and area A_3, two doors for entering and exiting the room are provided, which are areas through which employees frequently pass. Moreover, in the example of FIG. 17, the three areas A_7 to A_9 on the lower side of the figure are areas facing the outdoors, and outdoor natural light enters these three areas A_7 to A_9 as outside light. And In the example of FIG. 17, it is assumed that the remaining three areas A_4 to A_6 are areas that are not affected by external light.

  FIG. 18 is a diagram illustrating an example of a first weighting table describing first weights W1_n (W1_1 to W1_9) given to the respective areas A_n (A_1 to A_9) illustrated in FIG. The first weights W1_1 to W1_9 are values that reflect the characteristics of the positions of the corresponding areas A_1 to A_9, respectively. In the example of FIG. 18, the first weights W1_4 to W1_6 corresponding to the areas A_4 to A_6 that are not affected by the external light are 1.0, whereas the first weights W1_7 corresponding to the areas A_7 to A_9. ˜W1_9 is 0.7, which is a value smaller than 1.0 in consideration of outdoor natural light entering. Similarly, the first weights W1_1 to W1_3 corresponding to the areas A_1 to A_3 are also small values considering that the illumination light enters the hallway, but the first weights W1_1 corresponding to the areas A_1 and A_3. , W1_3 is a value larger than the first weight W1_2 corresponding to the area A_2 in consideration of frequent passage of employees. Specifically, the first weight W1_2 corresponding to the area A_2 is 0.8, whereas the first weights W1_1 and W1_3 corresponding to the areas A_1 and A_3 are 0.9.

  Note that the first weighting table in FIG. 18 is merely an example, and the size of the first weight for each area depends on the magnitude of the influence of external light, the characteristics of the positions of various areas to be considered, and the like. And determine the optimal value. For example, when there is an area used as a rest space in the room, the dimming level of the LED lighting device 500 corresponding to this area is lowered by setting the first weight corresponding to this area to a small value, The illuminance of the area can be made relatively small. Also, for example, when there is an area where office equipment commonly used by many employees is installed in the room, the LED corresponding to this area is set by setting the first weight corresponding to this area to a large value. The illuminance of the area can be relatively increased by increasing the dimming level of the lighting device 500.

  Moreover, it is also possible to change the 1st weight for every area according to time. For example, the interval from the office start time to the end time is divided into several time zones, and a plurality of first weighting tables corresponding to each time zone are stored in the first weighting table storage unit 222. And the weight provision part 211a of the lighting equipment control part 211 acquires time information from the timer provided inside the control server apparatus 200 or the outside of the control server apparatus 200, and corresponds to the first time zone corresponding to the time zone including the current time. By assigning the first weight to each area with reference to the weighting table, it is possible to change the first weight for each area according to time. Thus, if the first weight for each area is changed according to time, for example, it is possible to perform dimming control that more faithfully reflects the influence of outdoor natural light that changes according to time. .

  The second weighting table storage unit 223 is assigned to the area type corresponding to the position of the employee in the room that is the control target area, the condition given to each area type, and the area that matches the condition. The second weighting table in which the weights are described in association with each other is stored. Here, the area type indicates whether the employee is staying in the area (hereinafter referred to as stay area) or whether the employee is not staying (hereinafter referred to as non-stay area). Yes. The condition given to the stay area is the operating situation of the staying employee, that is, whether the employee is sitting at the desk, standing up or walking. The condition given to the non-stay area is a distance from the stay area. The distance from the stay area is distance = 1 if the area is adjacent to the stay area, distance = 2 if the area is not adjacent to the stay area and is adjacent to the area of distance = 1, and the distance is also 1 for the stay area. If the area is adjacent to the area of distance = 2, the distance = 3.

  FIG. 19 is a diagram illustrating an example of the second weighting table. In the example of FIG. 19, the area type is a stay area, and the second weight W2_n given to an area where the operating status of the staying employee is seated is 1.0. The area type is a stay area, and the second weight W2_n given to an area where the operating status of the staying employee is standing or walking is set to 0.8. Further, the area type is a non-stay area, and the second weight W2_n given to the area of distance = 1 from the stay area is 0.7. In addition, the area type is a non-stay area, and the second weight W2_n given to the area of distance = 2 from the stay area is set to 0.6. In addition, the area type is a non-stay area, and the second weight W2_n given to the area of distance = 3 from the stay area is set to 0.5.

  As shown in the example of FIG. 19, the second weight W2_n given to the non-stay area is set to a relatively smaller value than the second weight W2_n given to the stay area. Power saving can be achieved by lowering the dimming level of the LED lighting device 500 corresponding to the stay area. Also, for the stay area, the second weight W2_n is changed according to the operation status of the employee, and the second weight W2_n given to the stay area where the operation status of the employee is standing or walking is The LED lighting device corresponding to the stay area where the employee's operation status is standing or walking by setting the value to be smaller than the second weight W2_n given to the stay area where the employee's operation status is seated The dimming level of 500 can be lowered to save power. Further, with respect to the non-staying area, as the distance from the staying area increases, the value of the second weight W2_n to be given decreases so as to move away from the position of the employee in the room that is the control target area. As a result, the dimming level of the LED lighting device 500 can be lowered to reduce the uncomfortable feeling given to the employee.

  Note that the second weighting table in FIG. 19 is merely an example, and the value of the second weight W2_n given to the condition for each area type and the area that meets each condition is appropriately set according to the purpose and application. It can be changed and implemented.

  The weight assigning unit 211a of the lighting device control unit 211 refers to the first weighting table and the second weighting table, and for each area in the room that is the control target area, the first weight and the second weight Is granted. Specifically, the weight assigning unit 211a performs a stay area determination process, which will be described later, using the employee location information detected by the positioning server device 100 at predetermined time intervals. Then, the weight assigning unit 211a applies the corresponding second weight from the second weighting table to the area determined as the stay area based on the operation status of the employee detected by the positioning server device 100. Read and give. In addition, the weight assigning unit 211a calculates the distance from the stay area for the area determined to be a non-stay area, and based on the calculated distance, assigns the corresponding second weight from the second weighting table. Read and give.

The dimming control unit 211b includes the first weight assigned to the areas corresponding to the LED lighting devices 500, with the dimming levels of the plurality of LED lighting devices 500 dispersedly arranged in the room that is the control target area. Control is performed using the second weight. Specifically, the dimming control unit 211b, for example, for the LED lighting device 500 corresponding to the area A_n, the reference level Lb stored in the reference level storage unit 221 and the first weight assigned to the area A_n The target dimming level Lt is calculated by the following formula (1) from W1_n and the second weight W2_n assigned to the area A_n.
Lt = Lb × W1_n × W2_n (1)
Then, the dimming control unit 211b supplies a control signal for realizing the calculated target dimming level Lt to the PWM control circuit 501 of the LED lighting device 500.

  The LED lighting device 500 is supplied with DC power converted from an AC power supply 510 (commercial power supply 100/200 V) by the LED power supply unit 520. The PWM control circuit 501 of the LED lighting device 500 realizes dimming of the LED lighting device 500 by performing PWM control of the DC power supply based on the control signal supplied from the dimming control unit 211b. That is, the PWM control circuit 501 generates a PWM signal based on the control signal supplied from the dimming control unit 211b, and turns on / off the transistor provided in the LED drive circuit 502 according to the PWM signal. Dimming is achieved by adjusting the effective voltage of the DC power supply.

  FIG. 20 is a circuit diagram illustrating a schematic configuration of the LED lighting device 500. The LED drive circuit 502 includes a light emitting unit 502a composed of a plurality of LEDs connected in series, and a transistor 502b connected to the light emitting unit 502a. The base of the transistor 502b is connected to the PWM control circuit 501, and on / off of the transistor 502b is controlled in accordance with the PWM signal from the PWM control circuit 501.

  FIG. 21 is a diagram for explaining the outline of the PWM control. FIG. 21A shows the voltage waveform of the DC power supply when 100% is lit, that is, when the dimming level is 100%. FIG. 21B shows the voltage waveform of the DC power supply when 75% is lit, that is, when the dimming level is 75%. FIG. 21C shows the voltage waveform of the DC power supply when 50% is lit, that is, when the dimming level is 50%. FIG. 21D shows the voltage waveform of the DC power supply when 25% is lit, that is, when the dimming level is 25%. FIG. 21E shows the voltage waveform of the DC power supply when 0% is lit (off), that is, when the dimming level is 0%. As shown in these figures, the PWM control is performed by adjusting the time width during which the DC power source having a constant voltage level is supplied to the light emitting unit 502a of the LED lighting device 500, thereby adjusting the light control of the LED lighting device 500. Control the level.

  In the present embodiment, the dimming control of the LED lighting device 500 is realized by adjusting the effective voltage of the DC power supply by PWM control. However, the present invention is not limited to this, for example, the voltage level is adjusted by analog control. By doing so, dimming control of the LED lighting device 500 may be realized.

  Next, a specific processing procedure of dimming control for the LED lighting device 500 by the lighting device control unit 211 of the present embodiment will be described. FIG. 22 is a flowchart illustrating an outline of processing performed by the lighting device control unit 211 of the present embodiment.

  First, the communication unit 201 receives detection result data from the positioning server device 100 (step S101). And the weight provision part 211a of the lighting equipment control part 211 performs a stay area determination process using the absolute position (employee's position information in the room) of the detection result data received by the communication part 201 in step S101 (step S101). S102).

  Next, the weight assigning unit 211a stores the result of the stay area determination process in step S102, the operation status (posture) of the detection result data received by the communication unit 201 in step S101, and the first weighting table storage unit 222. The first weight and the second weight to be assigned to each area in the room that is the control target area using the first weighting table and the second weighting table stored in the second weighting table storage unit 223 Are determined (step S103).

  Next, the dimming control unit 211b corresponds to each area using the first weight and the second weight given to each area in step S103 and the reference level stored in the reference level storage unit 221. Each target dimming level of the LED lighting device 500 is calculated, and a control signal based on the calculated target dimming level is supplied to the PWM control circuit 501 of the LED lighting device 500, so that the dimming level of each LED lighting device 500 is set. Control (step S104).

  Here, a method for calculating the coordinate information of the area used for the stay area determination process will be described. FIG. 23 is a diagram illustrating an example of a method for calculating area coordinate information. FIG. 23 is based on the layout of the LED lighting device 500 in the room illustrated in FIGS. 6 and 17.

  In the example of FIG. 23, with respect to the LED lighting device 500_5 installed in the center of the room, the LED lighting device 500_2 on the upper side in the drawing, the LED lighting device 500_4 on the left side in the drawing, the LED lighting device 500_6 on the right side in the drawing, It is assumed that the LED lighting devices 500_8 are adjacent to each other on the lower side in the drawing. Here, the coordinates of the LED lighting device 500_2 are (x2, y2), the coordinates of the LED lighting device 500_4 are (x4, y4), the coordinates of the LED lighting device 500_5 are (x5, y5), and the coordinates of the LED lighting device 500_6 are ( x6, y6), and the coordinates of the LED lighting device 500_8 are (x8, y8). These coordinates (x2, y2), (x4, y4), (x5, y5), (x6, y6), (x8, y8) are stored in the storage unit 220 as position data.

Consider the case where the coordinate information of the area A_5 corresponding to the LED lighting device 500_5 installed in the center of the room is calculated under such a premise. When the area A_5 corresponding to the LED lighting device 500_5 is defined as an area surrounded by four points P1, P2, P3, and P4, the coordinates of each point are P1 (x5a, y5a) and P2 (x5a, y5b), respectively. , P3 (x5b, y5b), P4 (x5b, y5a), and the area A_5 corresponding to the LED lighting device 500_5 can be expressed by four numerical values x5a, x5b, y5a, and y5b. The four numerical values of x5a, x5b, y5a, and y5b are the coordinates (x2, y2), (x4, y4), ( By using x5, y5), (x6, y6), and (x8, y8), it can be calculated as in the following formulas (2) to (5).
x5a = (x4 + x5) / 2 (2)
x5b = (x5 + x6) / 2 (3)
y5a = (y8 + y5) / 2 (4)
y5b = (y5 + y2) / 2 (5)

  With the above method, it is possible to calculate the coordinates of the areas A_1 to A_9 corresponding to the LED lighting devices 500_1 to 500_9 distributed in the room which is the control target area. If there is a direction where there is no adjacent LED lighting device 500, the coordinates of the indoor wall may be used as the coordinates of the area boundary in that direction. For example, since the LED lighting device 500_8 illustrated in FIG. 23 does not have an adjacent LED lighting device 500 on the lower side in the drawing, the y coordinate y8a of the points P1 and P4 that define the lower area boundary in the drawing is used. The y coordinate (= 0) of the lower wall in the figure may be used.

  Next, a specific example of the stay area determination process executed by the weight assigning unit 211a will be described. FIG. 24 is a flowchart illustrating a procedure of stay area determination processing. The weighting unit 211a repeatedly executes the stay area determination process shown in the flowchart of FIG. 24 at predetermined time intervals. In the following description, the position of the employee received from the positioning server device 100 by the communication unit 201 of the control server device 200 is expressed as coordinates (x, y).

  First, the weight assigning unit 211a sets the area to be determined as the area A_n, and sets an initial value (n = 1) to n (step S201).

  Next, the weight assigning unit 211a acquires coordinate information of the area A_n (Step S202). As described above, the coordinate information of the area A_n is expressed by four numerical values of xna, xnb, yna, and ynb. For example, these numerical values are calculated in advance and stored in the storage unit 220 or the like.

  Next, the weight assigning unit 211a compares the employee position (x, y) detected by the positioning server device 100 with the coordinate information xna, xnb, yna, ynb of the area A_n, and the area A_n stays. It is determined whether it is an area. That is, the weight assigning unit 211a determines whether or not the value of x is in the range of xna to xnb (step S203) and determines whether or not the value of y is in the range of yna to ynb. (Step S204). And when the value of x is in the range of xna to xnb (step S203: Yes) and the value of y is in the range of yna to ynb (step S204: Yes), the area A_n is defined as the staying area. The information indicating that the area A_n is a stay area is temporarily stored in the storage unit 220 or the like (step S205). On the other hand, when the value of x is not within the range of xna to xnb (step S203: No), or when the value of y is not within the range of yna to ynb (step S204: No), the area A_n is defined as a non-staying area. Judgment is made and information is not stored.

  Next, the weight assigning unit 211a increments the value of n (step S206), and whether or not the value of n exceeds the number of areas, that is, is a stay area or a non-stay area for all areas. It is determined whether or not the determination has been completed (step S207). If the value of n is equal to or less than the number of areas (step S207: No), the process returns to step S202 to acquire the coordinate information of the new area A_n, and the subsequent processing is repeated. On the other hand, if the value of n exceeds the number of areas (step S207: Yes), the stay area determination process is terminated.

  Next, specific examples of weight determination processing for each area by the weight applying unit 211a and dimming control by the dimming control unit 211b will be described. FIG. 25 is a flowchart showing the procedure of weight determination processing and dimming control for each area.

  First, the weight assigning unit 211a sets an area A_n as an area to which a weight is applied, and sets an initial value (n = 1) for n (step S301).

  Next, the weight assigning unit 211a refers to information temporarily stored in the storage unit 220, for example, as a result of the stay area determination process described above, and determines whether the area A_n is a stay area (step) S302). And if the area A_n is a stay area (step S302: Yes), the weight provision part 211a will be the operation | movement of the employee who stays in area A_n based on the detection result data which the communication part 201 received from the positioning server apparatus 100. It is determined whether the situation is sitting, standing or walking (step S303). Then, if the operating status of the employee staying in the area A_n is seated (step S303: Yes), the weight assigning unit 211a determines the stay area from the second weighting table stored in the second weighting table storage unit 223. In addition, the second weight W2_n corresponding to the seating condition in the operation status is acquired and given to the area A_n (step S304). On the other hand, if the operating situation of the employee staying in the area A_n is standing or walking (step S303: No), the weight assigning unit 211a is obtained from the second weighting table stored in the second weighting table storage unit 223. The second weight W2_n corresponding to the stay area and the condition of the standing or walking motion is acquired and given to the area A_n (step S305).

  Further, when it is determined in step S302 that the area A_n is a non-stay area (step S302: No), the weight assigning unit 211a searches for the stay area closest to the area A_n, and the area A_n from the nearest stay area is searched. The distance is calculated (step S306). In addition, what is necessary is just to set it as predetermined distance (for example, distance = 3), when all the areas in the room which are control object areas are non-stay areas. Then, the weight assigning unit 211a acquires the second weight W2_n corresponding to the non-staying area and the distance condition calculated in step S306 from the second weighting table stored in the second weighting table storage unit 223. And assigned to the area A_n (step S307).

  Next, the weight assigning unit 211a acquires the first weight W1_n associated with the area A_n from the first weighting table stored in the first weighting table storage unit 222, and assigns the first weight W1_n to the area A_n (Step S1). S308).

  Next, the dimming control unit 211b uses the first weight W1_n given to the area A_n in step S308 and the second weight W2_n given to the area A_n in step S304, step S305, or step S307 as a reference. The reference level stored in the level storage unit 221 is multiplied to calculate the target dimming level of the LED lighting device 500_n corresponding to the area A_n (step S309).

  Next, the dimming control unit 211b increments the value of n (step S310), and whether or not the value of n exceeds the number of areas, that is, the target dimming of all LED lighting devices 500 corresponding to all areas. It is determined whether or not the light level has been calculated (step S311). If the value of n is equal to or smaller than the number of areas (step S311: No), the process returns to step S302, and the process for the new area A_n is repeated. On the other hand, if the value of n exceeds the number of areas (step S311: Yes), the dimming control unit 211b determines the PWM control circuit 501 of each LED lighting device 500 based on the target dimming level calculated in step S309. By supplying the control signal, the dimming level of each LED lighting device 500 is controlled (step S312).
