<1-2. Overview of control system>
An overview of the control system 1 according to the first embodiment will be described with reference to FIG. The control system 1 is in a state (hereinafter, referred to as “home state”) such that the user U is at home in the house H or is returning home for home according to the situation of the user U who is a resident of the house H Whether or not the device 300 is installed in the house H is controlled based on the result of the determination. Here, the outline of the control system 1 will be described by dividing into two scenes: (1) a scene in which the user U is returning to the house H, and (2) a scene in which the user U is out of the house H.

  Before describing the two situations (1) and (2), an initial setting performed in advance in the mobile terminal 200 will be described. As the initial setting, a positioning function (hereinafter, referred to as “GPS positioning function”) using a GPS (Global Positioning System) provided in the mobile terminal 200, a Wi-Fi communication function, and / or a Bluetooth Enable the communication function. Also, the router 400 is registered in the portable terminal 200 as a reference position indicating the position of the house H and an AP (Access Point) used by the Wi-Fi communication function. In the following description, a case in which the GPS positioning function is used will be described. However, the positioning using the GPS is only an example of the positioning function, and the position of the portable terminal 200 may be measured by another method. In the following description, a case will be described in which Wi-Fi and Bluetooth are used. However, these are merely examples of the first network 500a and the third network 500c, respectively, and the first network 500a and the The three networks 500c may be configured.

  First, the scene (1) will be described. As shown in the approximate center of FIG. 2A, when the user U approaches the house H in order to return to the house H, (1) the user U That the mobile terminal 200 used by the user U and the device control apparatus 100 are connected via Wi-Fi that is the first network 500a, and (2) the mobile terminal 200 used by the user U and the door lock unit 300a (3) that the user U is located within the first predetermined range R1 by using the GPS positioning function of the portable terminal 200, and that the communication is connected via Bluetooth that is the third network 500c. When any one of 1) to (3) is detected, it is determined that the user U is at home in the house H. Here, the “first predetermined range” is a range from a reference position indicating the position of the house H, and is a range for determining that the user U is at home with respect to the house H. The first predetermined range may be, for example, a range within a radius of 30 m from the reference position.

  When determining that the user U is at home in the house H as described above, the device control device 100 controls the operation of the device 300 installed in the house H in the first mode. Here, the “first mode” is a control mode in which the device control apparatus 100 causes the device 300 to perform an operation when the user U is at home in the house H. When the first mode is set, what operation each device 300 is to perform may be appropriately set in advance for each device. The first mode is also referred to as a “control mode” collectively as a second mode described later.

  According to the above configuration, the device control apparatus 100 can determine that the user U is at home in the house H based on the position information of the mobile terminal 200 even if the communication is disconnected due to the state of the first network 500a. . Conversely, according to the above configuration, the device control apparatus 100 can control the first network 500a even in a situation where the positioning accuracy is poor, such as when the user U goes indoors in the GPS positioning function of the mobile terminal 200. Through the communication connection via the terminal, it can be determined that the user U is at home in the house H. As described above, it is possible to determine that the user U is at home in the house H by combining the two detection means, and therefore, the control system 1 accurately determines that the user U is at home, and Can control the operation of the device 300 installed in the device.

  Next, the situation (2) will be described. As shown in the upper right part of FIG. 2B, when the user U goes away from the house H to go out, the device control device 100 installed in the house H is connected to the portable terminal 200 used by the user and the first network 500a. It detects that communication via a certain Wi-Fi is disconnected. After detecting the disconnection of the Wi-Fi communication, the portable terminal 200 activates a GPS positioning function to measure the position of the portable terminal 200. Then, when the device control apparatus 100 detects that the user U is located outside the second predetermined range R2 by the GPS positioning function of the mobile terminal 200, the user U is not at home in the house H, in other words, the user U Is determined to be out of the office. Here, the “second predetermined range” is a range based on the position of the house H, and is a range for determining that the user U is not at home with respect to the house H. For example, the second predetermined range may be provided wider than the first predetermined range, and may be a range within a radius of 50 m from the house H.

  When determining that the user U is not at home in the house H as described above, the device control device 100 controls the operation of the device 300 installed in the house H in the second mode. Here, the “second mode” is a mode in which the device control apparatus 100 causes the device 300 to operate when the user is not at home in a specific house.

  According to the above configuration, even if the communication is disconnected due to the state of the first network 500a despite the fact that the user U is at home in the house H, the control system 1 uses the user U based on the position information of the mobile terminal 200. Is detected to be still within the second predetermined range R2, the erroneous determination that the user is out of the vehicle is not performed. That is, according to the above-described configuration, the control system 1 suppresses erroneous determination that the user is not at home in the house H due to the state of the first network 500a even though the user U is at home in the house H. can do. Also, the mobile terminal 200 does not always activate the GPS communication function, but activates the GPS communication function to start positioning after the communication with the first network 500a is disconnected. Power consumption can be reduced. As described above, since it is possible to determine that the user U is not at home by combining the two detection means, the control system 1 accurately determines that the user is not at home with power saving, and is installed in the house. Control the operation of the device.

<2. Functional Configuration>
<2-1. Device control device 100>
An example of a functional configuration of the device control device 100 according to the first embodiment will be described with reference to FIG. FIG. 3 is a block diagram illustrating an example of a functional configuration of the device control device 100. The device control device 100 can use a portable terminal device that can exchange data with other devices via the network 500, such as a tablet terminal or a smartphone. In the first embodiment, a dedicated program is installed on a general-purpose tablet terminal, and the tablet terminal is used as the device control device 100 by executing the program.

  The device control device 100 includes a processor 110, a storage unit 120, a communication unit 130, a signal transmission / reception unit 140, a display unit 150, and an input unit 160.

  The processor 110 includes an arithmetic and logic operation unit (such as a CPU) that processes arithmetic operations, logical operations, bit operations, and the like, and various registers. The processor 110 centrally controls each unit of the device control apparatus 100 by executing various programs including the control program P1 stored in the storage unit 120. The various registers are, for example, a program counter, a data register, an instruction register, a general-purpose register, and the like. Here, the “control program” refers to an application program that operates on the device control device 100 dedicated to the control system 1.

  The processor 110 realizes a function of controlling the operation of the device 300 by executing the control program P1. The functional units implemented by the processor 110 executing the control program P1 may include an acquisition unit 111, a determination unit 112, a control unit 113, and an adjustment unit 114.

  The acquisition unit 111 acquires the position information measured by the mobile terminal 200 via the second network 500b. Here, “position information” is information indicating the position of the mobile terminal 200, in other words, the position of the user U. The position information may be, for example, latitude and longitude coordinates of the mobile terminal 200 at a specific time measured using the GPS positioning function. Further, the position information may include a reference position indicating the position of the house H.

  The acquisition unit 111 may acquire position information from each of the plurality of mobile terminals 200 used by each of the plurality of users U.

  The determination unit 112 determines whether or not the user U is in the house H based on the connection status of communication with the mobile terminal 200 by the communication unit 130, the reference position stored in the storage unit 120, and the position information acquired by the acquisition unit 111. Is determined to be at home.

  The determination unit 112 detects the connection status of the communication. For example, the determination unit 112 transmits a communication connection request to the portable terminal 200 via the first network 500a by the communication unit 130, and detects that the communication has been connected when receiving a response to the connection request. Is also good. In addition, for example, the determination unit 112 transmits a communication connection request to the mobile terminal 200 via the first network 500a by the communication unit 130, and if a response to the connection request has not been received for a predetermined time, the communication is performed. The disconnection may be detected. Further, the determination unit 112 inquires, for example, the router 400, which is a relay / transfer device of the first network 500a, about the connection status of the portable terminal 200 to the first network 500a, and responds to the inquiry to make a connection status of the communication. May be detected.

  For example, the determination unit 112 may detect that communication between the mobile terminal 200 and at least one of the devices 300 is connected via the third network 500c. Specifically, the determination unit 112 may receive and detect the connection status from the mobile terminal 200 or the device 300.

  The determination unit 112 specifically detects that communication with the mobile terminal 200 has been connected, and the position of the user U indicated in the position information is located within a certain range from the house H. When it is detected, the user U may be determined to be at home. Further, the determination unit 112 detects that communication with the mobile terminal 200 has been disconnected, and also detects that the position of the user U indicated in the position information is located outside a certain range from the house H. In this case, it may be determined that the user U is not at home.

  According to the above configuration, the determination unit 112 determines whether the user U is at home using both the connection status of communication with the mobile terminal 200 and the positional relationship between the house H and the mobile terminal 200. be able to. Therefore, according to such a configuration, the determination unit 112 can accurately determine whether the user U is at home to control the operation of the device 300 installed in the house.

  For example, when communication with the mobile terminal 200 is connected by the communication unit 130, the determination unit 112 determines that the position information acquired by the acquisition unit 111 is continuously located within the first predetermined range R1 from the reference position a predetermined number of times. In a case where the user U is connected to the mobile terminal 200 and at least one of the devices 300 is connected via the third network 500c, it may be determined that the user U is at home in the house H.

  The “predetermined number of times” is the number of times provided to ensure the certainty of the position information. For example, in the case of position information based on the GPS positioning function, an error such as a skipping signal may occur in a signal received from a GPS satellite. When such an error occurs, the determination unit 112 may erroneously detect that the user U is located, for example, even though the user U is not located within the first predetermined range R1. For this reason, the determination unit 112 can ensure the certainty of the positional relationship by detecting the positional relationship between the house H and the mobile terminal 200 continuously for a predetermined number of times.

  The determination unit 112 acquires, for example, the “range of a radius of 30 m from the reference position” that is the range indicated by the first predetermined range R1 with reference to the area information stored in the storage unit 120. If the determination unit 112 detects that the mobile terminal 200 is located within a range of a radius of 30 m from the reference position three times, which is a predetermined number of times, based on the acquired position information, the user U It is determined that the house H is at home.

  “Area information” is information indicating the first predetermined range R1 and / or the second predetermined range R2. In the area information, at least one of the first predetermined range R1 and the second predetermined range R2 may be provided for each device. For example, there is a case where the air conditioner 300b is required to be operated earlier than the other devices 300 to make the room of the house H comfortable. On the other hand, the door lock unit 300a may want to be unlocked in a state where the user U is closer to the house H than the other devices 300 from the viewpoint of security. Therefore, the first predetermined range R1 of the air conditioner 300b is “100 m from the reference position”, and the first predetermined range R1 of the door lock unit 300a is “3 m from the reference position”. By providing such a structure, it is possible to cope with the above case. According to such a configuration, it is possible to provide the easy-to-use control system 1 that can control the operation according to the type of the device 300 and the like.

  For example, when the communication unit 130 connects the Wi-Fi communication that is the communication method of the first network 500a with the mobile terminal 200, the determination unit 112 (2) the position information acquired by the acquisition unit 111. Is located within a radius of 30 m from the reference position, which is the first predetermined range R1, three consecutive times, or (3) Bluetooth in which the portable terminal 200 and the door lock unit 300a are the third network 500c. In any of these cases (1) to (3), such as when it is detected that communication has been connected using communication, the user U may be determined to be at home.

  According to the above configuration, the determination unit 112 determines that the user U is at home in the house H based on the position information of the mobile terminal 200 even when communication is disconnected due to the state of the first network 500a and the state of the third network 500c. Can be detected. Conversely, according to the above-described configuration, the determination unit 112 can determine whether the first network 500a or the second network 500a or Through the communication connection via the third network 500c, it is possible to detect that the user U is at home in the house H.

  For example, after the communication with the mobile terminal 200 by the communication unit 130 is disconnected, the determination unit 112 determines that the position information acquired by the acquisition unit 111 is continuously outside the second predetermined range R2 from the reference position a predetermined number of times. In this case, it may be determined that the user U is not at home in the house H.

  The determination unit 112 may, for example, (1) after 60 seconds elapse in a state in which the communication unit 130 disconnects the Wi-Fi communication, which is the communication method of the first network 500a with the mobile terminal 200, (2) the acquisition unit 111 Even if it is determined that the user U is not at home in the house H when the position information acquired by the above is located outside the radius 50 m that is the second predetermined range R2 from the reference position three consecutive times, which is the predetermined number of times, Good.

  According to the above configuration, the determination unit 112 determines the user U based on the position information of the mobile terminal 200 even if the communication is disconnected due to the state of the first network 500a even though the user U is at home in the house H. If is still within the second predetermined range R2, it is not erroneously determined that the user is out. That is, according to the above configuration, the determination unit 112 suppresses erroneous determination that the user is not at home in the house H due to the state of the first network 500a even though the user U is at home in the house H. can do.

  For example, when the communication unit 130 communicates with a plurality of mobile terminals used by a plurality of users U, and the obtaining unit 111 obtains position information from each of the plurality of mobile terminals, It may be determined whether or not each of the users is at home in the house H.

  For example, based on the position information acquired by the acquisition unit 111, the determination unit 112 is located within the first predetermined range R1 from the reference position for a predetermined number of consecutive times, and sequentially approaches the reference position. U may be determined to be at home in house H. For example, even when the user U does not return to the house H but simply passes through the first predetermined range R1, the user U may be located in the first predetermined range R1 continuously for a predetermined number of times. In order to prevent the determination that the user U is in the home state in such a case, the determination unit 112 determines, for example, Compare the distance differences. The determination unit 112 determines that the user U is approaching the reference position sequentially and determines that the user U is at home when the user U sequentially decreases the distance with respect to the reference position over time based on the result of the determination. Can be determined. On the contrary, based on the position information acquired by the acquisition unit 111, the determination unit 112 is located within the second fixed range R2 from the reference position continuously for a predetermined number of times, and sequentially moves away from the reference position, It may be determined that the user U is not at home in the house H. According to such a configuration, the determination unit 112 can more accurately determine whether the user is at home.

  The control unit 113 is a control unit that can control the operation of the device 300 installed in the house H, and controls the operation of the device 300 in the first mode when the determination unit 112 determines that the device is in the home state. When the determination unit 112 determines that the device is not at home, the operation of the device 300 is controlled in the second mode.

  For example, in the case of the first mode, when the user U is at home, the control unit 113 unlocks the door lock unit 300a, activates (ON) the air conditioner 300b, and activates the robot cleaner. If it is 300c, it is controlled to stop (OFF) if it has been operating (ON) while going out. Further, for example, in the case of the second mode, when the user U is not in the home state, the control unit 113 locks the door lock unit 300a if the user U is operating at home while the air conditioner 300b operates when the user U is not at home. Control is performed so as to stop and operate the robot cleaner 300c.

  For example, when detecting a change in the connection status of communication with the mobile terminal 200 or a change in the positional relationship between the house H and the mobile terminal 200, the control unit 113 transmits the device 300 corresponding to the detected status to the device 300. A control signal for executing an operation according to the detected situation or the like is generated and transmitted. When receiving the generated control signal from the device control device 100, the device 300 operates according to the control signal.

  When the determination unit 112 determines that at least one of the plurality of users is at home in the house H, the control unit 113 controls the operation of the device 300 in the first mode. When it is determined that all the users are not at home, the operation of the device 300 may be controlled in the second mode.

  For example, when there are a plurality of users for one house H, for example, a plurality of residents, even if one of the residents goes out of the house H, the other residents may still be at home. Conversely, even if not all of the residents have returned home, if one of the residents has returned to the house H, the state is at home. For this reason, for example, when there are three users for one house H, the control unit 113 determines that at least one of the three users is at home in the house H, It is possible to transition from the mode to the first mode. The control unit 113 can make a transition from the first mode to the second mode only when it is determined that all three users are not at home. According to such a configuration, a convenient control system can be provided even when a plurality of users exist for one house H.

  When the determination unit 112 determines that at least one of the plurality of users is at home in the house H, when the control unit 113 makes a transition from the second mode to the first mode, the control unit 113 transmits the plurality of users. A part or the whole may be notified of the transition to the first mode. Further, when the determination unit 112 determines that all of the plurality of users are not at home, when the control unit 113 shifts from the first mode to the second mode, the control unit 113 transmits a part of the plurality of users. Alternatively, all of them may be notified of the transition to the second mode. The control unit 113 transmits a notification message indicating the mode transition notification via the communication unit 130 via the communication unit 130 in order to display, on the portable terminal 200, a mode transition notification for notifying some or all of the plurality of users of the transition of the control mode. The data is transmitted to the mobile terminal 200. According to such a configuration, when there are a plurality of users for one house H, the control unit 113 determines that the user who has gone out of the house H first is also a resident user other than himself. Can be notified that it is no longer available.

  If the control unit 113 detects an abnormality in the device 300 when the control mode of the operation of the device transitions from the first mode to the second mode, the control unit 113 may notify the user U of the abnormality. For example, when the door lock unit 300a remains unlocked without being locked even though the second mode indicating the outside state of the user U has been entered, the control unit 113 detects this abnormality of the door lock unit 300a. It may be detected. The control unit 113 transmits an alert message indicating the device abnormality alert to the mobile terminal 200 via the communication unit 130 so that the device abnormality alert for notifying the user U of the detected abnormality is displayed on the mobile terminal 200. According to such a configuration, since the control unit 113 can notify the user U of a control abnormality of the operation of the device 300, the control system 1 with higher security can be provided.

  The adjusting unit 114 estimates speed information indicating the moving speed of the mobile terminal 200 based on the position information acquired by the acquiring unit 111, and determines the first predetermined range R1 or the second predetermined range R2 based on the speed information. Adjust at least one of them. For example, the time when the user U returns to the house H on a vehicle such as a car and the time when the user U returns home on foot are long even if the user U is located at the same position. different. The same applies when the user U goes out of the house H. For this reason, the adjustment unit 114 estimates the moving speed of the portable terminal 200 used by the user U from the position information for a certain period of time, and based on the moving speed, determines the first predetermined range R1 and / or the second predetermined range R2. Is adjusted, the difference in the return time due to the difference in the means of transportation can be eliminated. According to such a configuration, the adjustment unit 114 causes the determination unit 112 to determine whether or not the time from returning to home or the time after going out based on the positional relationship with the house H is at home without being biased by the moving means. be able to.
