(Embodiment 1)
FIG. 1 is a schematic diagram showing a configuration of an intrusion detection system 100 according to the first embodiment. The intrusion detection system 100 shown in FIG. 1 detects intrusion of a person or an object into the automatic door 10 and functions to open and close the automatic door. The intrusion detection system 100 detects an intrusion of a person or an object into the automatic door 10 shown in FIG. 1 and also detects the intrusion of a person or an object into an intrusion detection area in a security system such as a security device other than the automatic door. Used in the system.

  The intrusion detection system 100 includes an automatic door 10, an automatic door sensor 20, an intrusion determination unit 30, a door controller 40, and the like. The automatic door 10 in the intrusion detection system 100 shown in FIG. 1 is a double door type, and two automatic doors 10 automatically open and close to the left and right. The automatic doors 10 are a pair of left and right, and are capable of reciprocating along a fix 15 which is fixedly arranged with a space left and right, and opens and closes an opening 11 between the left and right fixes 15.

  The automatic door 10 is in a fully closed state in which the left and right door end frames 10a are brought into contact with each other and the openings 11 are closed. The automatic door 10 moves so that the door frame 10a is separated, the door frame 10a moves to the vicinity of the upright 15a of the fix 15 and stops, and the opening 11 is opened and is in a fully opened state. The automatic door 10 may be a double-sliding door type, a single-sliding door type, a revolving door type, or the like.

  The automatic door sensor 20 is arranged, for example, in the eyeless portion 16 above the opening portion 11, and projects infrared light obliquely downward from the arrangement position in the eyeless portion 16 to form an intrusion detection area. The automatic door sensor 20 acquires physical information obtained from a plurality of areas in the intrusion detection area and monitors whether a person or an object has entered the intrusion detection area. Physical information obtained from a plurality of areas in the intrusion detection area is input to the intrusion determination unit 30. Further, the automatic door sensor 20 determines whether a person or an object has entered the intrusion detection area based on physical information obtained from a plurality of areas in the intrusion detection area, and outputs the determination result to the door controller 40. Details of the automatic door sensor 20 will be described later.

  The intrusion determination unit 30 acquires at least a part of the physical information obtained from a plurality of areas in the intrusion detection area from the automatic door sensor 20, estimates the moving state (for example, moving speed) of a person or an object, and defines the automatic door sensor 20. It is independently determined whether a person or an object has entered the intrusion detection area, and the determination result is output to the door controller 40.

  The door controller 40 acquires the determination result of whether a person or an object has entered the intrusion detection area from the automatic door sensor 20 and the intrusion determination unit 30, and operates the door motor 50 so that the automatic door 10 opens or closes. To drive. Further, after the automatic door 10 is fully opened, the door controller 40 keeps the fully open state for a certain period of time, operates the door motor 50 in the reverse direction, and drives the automatic door 10 until it is fully closed.

  FIG. 2 is a block diagram showing a functional configuration of the intrusion detection system 100 according to the first embodiment. Each block can be realized by an electronic element such as a CPU of a computer, a mechanical component, or the like in terms of hardware, and can be realized by a computer program or the like in terms of software. Drawing a functional block. Therefore, it will be understood by those skilled in the art that these functional blocks can be realized in various forms by combining hardware and software.

  The automatic door sensor 20, the intrusion determination unit 30, and the door controller 40 are communicatively connected to each other via a CAN (Controller Area Network) bus. The communication connection of the automatic door sensor 20, the intrusion determination unit 30, and the door controller 40 is not limited to CAN, and wired or wireless communication such as Ethernet (registered trademark) or WiFi (registered trademark) may be used.

  The automatic door sensor 20 includes a sensor unit 21 as a detection element, a determination unit 22, an output unit 23, a state confirmation unit 24, a state output unit 25, and a display unit 26. The sensor unit 21 is an infrared reflection type sensor, and includes a light projector that projects infrared light onto an intrusion detection area, which will be described later, and a light receiver that receives reflected light from a person or an object. The automatic door sensor 20 corresponds to the detecting unit and the detecting device in the present invention.

  FIG. 3 is a schematic diagram showing an intrusion detection area 60 on the floor of the sensor unit 21. The intrusion detection area 60 has a three-dimensional range from the floor surface to the seamless 16 where the automatic door sensor 20 is arranged and the ceiling. The intrusion detection area 60 is composed of a plurality of regions 61 arranged in 12 rows in a direction parallel to the moving direction of the automatic door 10 and 6 rows in a direction orthogonal to the moving direction of the automatic door 10. Addresses 1A, 1B, ..., 6K, 6L corresponding to the positions of the array are allocated to each area 61. Each assigned address corresponds to the position information of each area 61.

  The shape of each area 61 and the overall shape of the intrusion detection area 60 may be a circle, an ellipse, a rectangle, or a polygon other than the rectangle. Further, the sensor unit 21 detects by a Doppler effect using radio waves or sound waves, detects by a camera to acquire an image and performs image processing, detects by measuring a distance to a person or an object, far infrared rays. It is possible to use one that detects the presence of a person or an object based on the amount of received light, or one that detects by thermography.

  In the intrusion detection area 60, a plurality of areas 61 near the automatic door 10 are protection detection areas 62. In the example shown in FIG. 3, the protection detection area 62 includes areas 61 with addresses 1A to 1L surrounded by dotted lines. When a person or an object enters the protection detection area 62, the automatic door 10 is driven in the opening direction and is controlled so as to maintain the opened state. The configuration of the protection detection area 62 is not limited to the example shown in FIG. 3, and includes, for example, a configuration that does not include the area 61 of the addresses 1A and 1L and an area 61 of the addresses 2A to 2L that corresponds to the second column near the automatic door 10. Such a configuration may be used. The protection detection area 62 corresponds to the specific area in the present invention.

  The judgment unit 22 includes a basic judgment unit 22a and a protection judgment unit 22b. The basic determination unit 22a sets the entire intrusion detection area 60 as a determination target for determining whether a person or an object has intruded. On the other hand, the protection determination unit 22b sets the protection detection area 62 of the intrusion detection area 60 as a determination target for determining whether a person or an object has entered.

  The basic determination unit 22a and the protection determination unit 22b monitor the detection level of infrared light, which is the physical information corresponding to each area 61 of the intrusion detection area 60, and determine the predetermined level when there is no person or object in each area 61. When it exceeds or falls below the reference level, it is determined that a person or object has entered. FIG. 4 is a schematic diagram for explaining whether or not a person or an object has entered. The basic determination unit 22a and the protection determination unit 22b determine the upper limit threshold and the lower limit threshold of the infrared light detection level corresponding to each region 61 of the intrusion detection area 60. The reference level is between the upper limit threshold and the lower limit threshold, and there is no person or object. For example, when the appearance of a person or object is white, it can be seen that the reflection is strong and the detection level becomes higher than the upper limit threshold (reference level), and the person or object has entered. Further, when the appearance of a person or an object is blackish, the reflection becomes weak and the detection level becomes lower than the lower limit threshold (reference level), and it can be seen that a person or an object has entered.

  The output unit 23 has a basic determination output unit 23a and a protection determination output unit 23b. The basic determination output unit 23a outputs the determination result by the basic determination unit 22a to the door controller 40. The basic determination output unit 23a outputs to the intrusion determination unit 30 the determination result of the basic determination unit 22a or the detection level of infrared light which is physical information corresponding to each region 61 of the intrusion detection area 60. When outputting the detection level of infrared light, which is physical information, to the intrusion determination unit 30, the basic determination output unit 23a may output the data after A / D conversion, for example. The basic determination output unit 23a may output the determination result corresponding to all the areas 61 of the intrusion detection area 60 or the detection level of infrared light, which is physical information, to the intrusion determination unit 30. Alternatively, the detection level of infrared light, which is physical information, may be output together with the position information of the area where it is determined that a person or an object has entered.

  Similarly, the protection determination output unit 23b outputs the determination result by the protection determination unit 22b to the door controller 40. The protection determination output unit 23b outputs to the intrusion determination unit 30 a determination result of the protection determination unit 22b or a detection level of infrared light which is physical information corresponding to each area 61 of the protection detection area 62. When outputting the detection level of infrared light, which is physical information, to the intrusion determination unit 30, the protection determination output unit 23b may output the data after A / D conversion, for example. Further, the protection determination output unit 23b may output the determination result corresponding to all the regions 61 of the protection detection area 62 or the detection level of infrared light, which is physical information, to the intrusion determination unit 30. Alternatively, the detection level of infrared light, which is physical information, may be output together with the position information of the area where it is determined that a person or an object has entered.

  The state confirmation unit 24 confirms whether or not the intrusion determination unit 30 is in a state in which it can determine the intrusion of a person or an object into the intrusion detection area 60. When the intrusion determination unit 30 is in a state in which the intrusion determination unit 30 can determine the intrusion of the person or the object into the intrusion detection area 60, the state confirmation unit 24 determines that the intrusion determination unit 30 is operating normally, and detects the intrusion of the person or the object. If it cannot be determined, it is determined that the operation is abnormal. For example, the state confirmation unit 24 confirms whether the intrusion determination unit 30 is operating normally or abnormally by periodically polling whether the output of the intrusion determination unit 30 is for a certain time.

  In response to the result of the confirmation by the state confirmation unit 24, the state output unit 25 determines that the intrusion determination unit 30 is abnormal when the intrusion determination unit 30 cannot determine the intrusion of a person or an object into the intrusion detection area 60. Is output to the door controller 40.

  The display unit 26 is composed of an LED, a liquid crystal display device, or the like, and displays the operating state (normal or error occurrence) of the automatic door sensor 20, the intrusion determination unit 30, the door controller 40, and the like to notify the outside. Instead of the display unit 26, a voice generation unit (not shown) for notifying the operating state to outside by voice or the like may be provided.

  The intrusion determination unit 30 has an addition determination unit 31 and a determination output unit 32, and is electrically detachably connected to the CAN bus by a connector 35. The intrusion determination unit 30 may be connected to the CAN bus by the connector 35, or may be electrically detachably connected to the automatic door sensor 20 not via the CAN bus but via a separate connector. The intrusion determination unit 30 corresponds to the intrusion determination unit and the intrusion determination device in the present invention.

  The addition determination unit 31 calculates the moving speed and the moving direction of a person or an object based on the information input from the automatic door sensor 20, and when the calculation result exceeds a predetermined reference, the addition determination unit 31 enters the intrusion detection area 60. Judge that a person or object has invaded. The addition determination unit 31, for example, when the moving speed and the moving direction of the person or the object is calculated, when the person or the object is stopped, or when the movement is such that the person or the object simply crosses in front of the automatic door 10, It is determined that a person or an object has entered, but the automatic door 10 is not opened to enter.

  When acquiring the determination result by the basic determination unit 22a from the automatic door sensor 20, the addition determination unit 31 determines the moving speed and the moving direction based on the history of the position information of the area 61 in which it is determined that a person or an object has entered. calculate. Further, when acquiring the detection level of infrared light, which is the physical information corresponding to each area 61 of the intrusion detection area 60, from the automatic door sensor 20, the addition determination unit 31 determines by itself the upper threshold and the lower threshold, The moving speed, the moving direction, and the like are calculated based on the history of the position information of the area 61 in which the object is determined to have entered.

  When the addition determination unit 31 calculates the moving speed and the moving direction of a person or an object in addition to the physical information acquired by the automatic door sensor 20 and determines that the state is not the intrusion state for opening the automatic door 10, It is determined that no person or object has entered the intrusion detection area 60. In addition, the addition determination unit 31 calculates the moving speed and the moving direction of the person or the object, and when it is determined that the person or the object is heading toward the automatic door 10 and is in the intrusion state for opening the automatic door 10. It is determined that a person or an object has entered the intrusion detection area 60.

  The judgment output unit 32 outputs the judgment result of the addition judgment unit 31 to the door controller 40. As described above, even when the automatic door sensor 20 obtains the physical information or the determination result that a person or an object has entered any one of the areas 61 of the intrusion detection area 60, the addition determination unit 31 detects the automatic door 10 as well. It may not be necessary to open the door, and the determination output unit 32 may output that no person or object has entered the intrusion detection area 60.

  The door controller 40 controls the opening and closing of the automatic door 10 based on the output from the automatic door sensor 20 when the intrusion determination unit 30 is not connected. Further, the door controller 40 controls the opening and closing of the automatic door 10 based on the output from the intrusion determination unit 30 when the intrusion determination unit 30 is connected. When the door controller 40 acquires the output information indicating that a person or an object has entered the protection detection area 62 from the protection determination output unit 23b of the automatic door sensor 20, even if the intrusion determination unit 30 is connected, the output concerned. The automatic door 10 is controlled to the open state based on the information.

  Next, the operation of the intrusion detection system 100 will be described. FIG. 5 is a flowchart showing a procedure of an intrusion detection process in the automatic door sensor 20. The intrusion detection system 100 acquires the physical information in each area 61 of the intrusion detection area 60 by the automatic door sensor 20 (S1). The automatic door sensor 20 transmits the acquired physical information to the intrusion determination unit 30 via the CAN bus (S2). The state confirmation unit 24 of the automatic door sensor 20 confirms the state (normal or abnormal) of the intrusion determination unit 30 (S3).

  Based on the confirmation by the state confirmation unit 24, it is determined whether the intrusion determination unit 30 is operating normally (S4). When it is determined in step S4 that the operation is not normal (S4: NO), the state output unit 25 transmits information indicating that the intrusion determination unit 30 is abnormal to the CAN bus, and blinks the display unit 26 to intrude. The determination unit 30 is notified that it is abnormal (S5). When it is determined in step S4 that the operation is normal (S4: YES), and after step S5, the protection determination unit 22b determines that a person or an object has entered the protection detection area 62 based on the physical information acquired by the automatic door sensor 20. Is determined (S6). The protection determination unit 22b determines whether the physical information acquired in each area 61 of the protection detection area 62 exceeds the upper limit threshold value or falls below the lower limit threshold value (S7).

  In step S7, when the physical information acquired in each area 61 of the protection detection area 62 exceeds the upper limit threshold value or falls below the lower limit threshold value (S7: YES), the protection determination output unit 23b moves to the protection detection area 62. Alternatively, the result of the determination that the object has entered is output to the CAN bus (S8), and the processing is ended. In step S7, when the physical information acquired in each region 61 of the protection detection area 62 does not exceed the upper limit threshold and does not fall below the lower limit threshold (S7: NO), the process ends. In addition, in step S7, when the physical information acquired in each area 61 of the protection detection area 62 does not exceed the upper limit threshold value and does not fall below the lower limit threshold value (S7: NO), a person or an object enters the protection detection area 62. You may output the determination result that it has not invaded to the CAN bus.

  The automatic door sensor 20 confirms the normal operation of the intrusion determination unit 30 by repeating Step S1 to Step S8, and if an abnormality occurs, the automatic door sensor 20 indicates to the CAN bus that the intrusion determination unit 30 is abnormal. You can inform 40. The door controller 40 may stop the operation of the automatic door 10 or continue the operation of the automatic door 10 based on the output information of the automatic door sensor 20 when the intrusion determination unit 30 is in an abnormal state. . Further, the fact that the intrusion determination unit 30 is abnormal is notified by the display unit 26, so that it can be notified to the outside that maintenance such as inspection or repair is necessary.

  Further, the automatic door sensor 20 outputs the entry of a person or an object to the protection detection area 62 to the CAN bus from the protection determination output section 23b regardless of whether the intrusion determination section 30 is operating normally or abnormally. , The door controller 40 can be notified. The door controller 40 can control the automatic door 10 to be in an open state in response to the entry of a person or an object into the protection detection area 62.

  FIG. 6 is a flowchart showing the procedure of the intrusion detection process in the intrusion determination unit 30. The intrusion determination unit 30 acquires the physical information in each area 61 of the intrusion detection area 60 via the CAN bus (S11). The addition determination unit 31 calculates the moving speed and moving direction of a person or an object that has entered the intrusion detection area 60 based on the acquired physical information (S12). The addition determination unit 31 determines whether or not the calculated moving speed and moving direction satisfy a detection condition such as a person or an object moving toward the automatic door 10 (S13). Here, the detection condition is determined based on the moving speed and the moving direction of the person or the object as described above, for example, that the person or the object is heading toward the automatic door 10 and is an intrusion state for opening the automatic door 10. This is a possible condition.

  When the addition determination unit 31 determines that the detection condition is satisfied (S13: YES), the determination output unit 32 outputs the determination result that a person or an object has entered the intrusion detection area 60 to the CAN bus (S14). , The process ends. When the addition determination unit 31 determines in step S13 that the detection condition is not satisfied (S13: NO), the process ends. Further, when the addition determination unit 31 determines that the detection condition is not satisfied (S13: NO), the determination output unit 32 outputs the determination result that no person or object has entered the intrusion detection area 60 to the CAN bus. You may do it. The intrusion determination unit 30 outputs the determination result to the door controller 40 by repeating steps S11 to S14.

  The door controller 40 controls the opening and closing of the automatic door 10 based on the output from the automatic door sensor 20 when the intrusion determination unit 30 is not connected. The intrusion detection system 100 can be retroactively changed to a more advanced intrusion detection algorithm by connecting the intrusion determination unit 30. Further, the intrusion detection system 100 does not need to replace the automatic door sensor 20 and the like, and can execute a necessary intrusion detection algorithm without excessively using hardware resources.

  In addition to the presence of a person or an object in the intrusion detection area 60, the intrusion determination unit 30 determines whether or not the intrusion state is to open the automatic door 10 based on the moving speed and the moving direction of the person or the object. Yes, and can provide additional and advanced intrusion decisions. The door controller 40 opens and closes the automatic door 10 based on the determination result output from the intrusion determination unit 30, thereby enabling the automatic door 10 to be opened and closed based on the determination result based on the moving speed and moving direction of a person or an object. And

  FIG. 7 is a flowchart showing another procedure of the intrusion detection process in the automatic door sensor 20. The processing from step S21 to step S24 shown in FIG. 7 is equivalent to the processing from step S1 to step S4 shown in FIG. 5, and the description thereof is omitted for brevity. When the intrusion determination unit 30 determines in step S24 that the operation is not normal (S24: NO), the basic determination unit 22a determines whether or not a person or an object has entered the intrusion detection area 60 based on the physical information acquired by the automatic door sensor 20. A judgment is made (S25). The basic determination unit 22a determines whether the physical information acquired in each area 61 of the intrusion detection area 60 exceeds the upper limit threshold value or falls below the lower limit threshold value (S26).

  In step S26, when the physical information acquired in each region 61 of the intrusion detection area 60 exceeds the upper limit threshold value or falls below the lower limit threshold value (S26: YES), the basic determination output unit 23a moves to the intrusion detection area 60. Alternatively, the determination result that the object has entered is output to the CAN bus (S27). When the intrusion determination unit 30 determines in step S24 that the operation is normal (S24: YES), the physical information acquired in each region 61 of the intrusion detection area 60 does not exceed the upper limit threshold and the lower limit threshold is set in step S26. If it is not below (S26: NO), and after step S27, the process moves to step S28, and the intrusion of a person or an object into the protection detection area 62 is determined by the protection determination unit 22b (S28). In FIG. 7, the processing from step S28 to step S30 is the same as the processing from step S6 to step S8 shown in FIG. 5, and the description thereof is omitted for brevity. The intrusion determination unit 30 is assumed to be executing the process based on the flowchart shown in FIG.

  When the intrusion determination unit 30 is abnormally operating, the automatic door sensor 20 determines the intrusion of a person or an object into the intrusion detection area 60 by the processing from step S25 to step S27, and outputs the determination result to the CAN bus. is doing. Thereby, the door controller 40 controls the opening / closing of the automatic door 10 based on the determination result from the automatic door sensor 20 regardless of the determination result from the intrusion determination unit 30 when the intrusion determination unit 30 is abnormally operating. You can continue.

  FIG. 8 is a flowchart showing still another procedure of the intrusion detection process in the automatic door sensor 20. The process from step S31 to step S37 shown in FIG. 8 is the same as the process from step S21 to step S27 shown in FIG. 7, and the description thereof will be omitted for brevity. In the process flow shown in FIG. 8, the process of determining the intrusion of a person or an object into the protection detection area 62 (steps S28 to S30 shown in FIG. 7) is omitted. Even when the automatic door sensor 20 is not provided with the protection determination unit 22b that determines the intrusion of a person or an object into the protection detection area 62, the same processing as in FIG. 7 can be performed on the intrusion detection area 60.

  In the processing based on the flowcharts of FIGS. 7 and 8, when the intrusion determination unit 30 becomes abnormal, the basic determination unit 22a determines that a person or an object has entered the intrusion detection area 60, and the door controller 40 causes the automatic door 10 to operate. The open / close control of is continued. Here, when the intrusion determination unit 30 returns from the abnormal operation to the normal operation, the processing from step S25 to step S27 in FIG. 7 and the processing from step S35 to step S37 in FIG. 8 are skipped. As a result, when the intrusion determination unit 30 returns from the abnormal operation to the normal operation, the determination by the basic determination unit 22a and the output from the basic determination output unit 23a stop, and the determination result of the intrusion determination unit 30 returns to the normal operation. The door controller 40 controls the opening and closing of the automatic door 10 based on the above.

(Embodiment 2)
FIG. 9 is a block diagram showing a functional configuration of the intrusion detection system 100 according to the second embodiment. The intrusion determination unit 30 according to the second embodiment includes a biometric information determination unit 33. The intrusion detection system 100 according to the second embodiment is provided with the biometric information determination unit 33 and has the same configuration and operation as those of the first embodiment other than those specifically described below, and the description thereof will be omitted for brevity.

  The biometric information determination unit 33 of the intrusion determination unit 30 permits the automatic door 10 to be opened by a person or an object (having information corresponding to the biometric information of a person) having biometric information registered in advance. The biometric information determination unit 33 does not permit opening of the automatic door 10 even if a person or an object that does not have biometric information registered in advance enters the automatic door 10. The biometric information is, for example, information such as a face, pupils, and voiceprint, and may be any information that can identify a person or an object. The biometric information is registered in advance in a storage device (not shown). The biometric information determination unit 33 compares the biometric information extracted from the person or the object that has entered the automatic door 10 with the biometric information registered in advance in the storage device to determine whether or not they match.

  For example, a person or an object is imaged by an image sensor to extract biometric information. When the automatic door sensor 20 is an image sensor, biometric information is extracted using an image captured by the automatic door sensor 20. If the automatic door sensor 20 uses a method other than the image sensor, an image sensor for photographing a person or an object may be provided. Further, a microphone for acquiring voice may be provided when extracting and collating a voiceprint or the like, and a detector corresponding to the biometric information may be provided when using other biometric information.

The processing from step S41 to step S43 shown in FIG. 10 is equivalent to the processing from step S11 to step S13 in FIG. 6, and the description thereof will be omitted for brevity. In step S43, when the addition determination unit 31 determines that the moving direction, the moving speed, and the like satisfy the detection conditions (S43: YES), the biometric information of the intruding person or object is extracted (S44).

  The biometric information determination unit 33 determines whether or not there is a person or object that is not registered in advance in the extracted biometric information (S45). When there is a person or object that has not been registered in advance (S45: YES), the biometric information determination unit 33 outputs information indicating that there is a person or object that is not permitted to enter (S46), and the processing ends. . In this case, information indicating that a person or an object is not permitted to enter may be notified to the outside by voice or display.

  When it is determined by the biometric information determination unit 33 that there is no person or object not registered in advance (S45: NO), the determination output unit 32 determines the determination result that the person or object has entered the intrusion detection area 60. The data is output to the CAN bus (S47), and the process ends. If the addition determination unit 31 determines in step 43 that the moving direction, the moving speed, and the like do not satisfy the detection conditions (S43: NO), the process ends. The intrusion determination unit 30 repeats the processing from step S41 to step S47.
