It is a block diagram of a surveillance camera control system. It is a flowchart which shows the processing routine of a surveillance camera control program.

  An embodiment of the present invention will be described.

  As shown in FIG. 1, the surveillance camera control system 10 according to the present embodiment includes a thermoelectric supply device 12, a surveillance camera control device 14, a power device group 16, a hot water supply device group 18, a smartphone 20, and a surveillance camera 22. .

  The thermoelectric supply device 12 is a so-called cogeneration system, and includes a power generation unit 12A, a hot water storage unit 12B, a power meter 12C, and a hot water supply meter 12D.

  In this embodiment, the power generation unit 12A is a fuel cell unit including a fuel cell that generates power using, as an example, hydrogen generated from a gas such as city gas. The power generation unit using a gas engine or the like is not limited to the fuel cell. The power generated by the power generation unit 12A is supplied to each power device 16A included in the household power device group 16 in which the thermoelectric supply device 12 is installed.

  The hot water storage unit 12B includes a tank (not shown) to which water is supplied, uses the heat generated by the power generation unit 12A to generate water, warms the water in the tank, and supplies hot water in the home where the thermoelectric supply device 12 is installed. Hot water is supplied to each hot water supply device 18A included in the device group 18.

  The wattmeter 12 </ b> C detects the amount of power consumed by the power device group 16. The detected power consumption is output to the surveillance camera control device 14.

  When the demand for the power load of the power device group 16 is not sufficient only from the power supplied from the thermoelectric supply device 12, the power shortage is supplemented by the system power supplied from the system power supply of the power company.

  In addition, when the demand for hot water supply of the hot water supply device group 18 is not sufficient only by the hot water supplied from the thermoelectric supply device 12, a backup boiler (not shown) is operated to compensate for the shortage of hot water.

  The hot water supply amount meter 12D detects the consumption amount of hot water consumed by the hot water supply device group 18. The detected consumption amount of hot water is output to the monitoring camera control device 14.

  The surveillance camera 22 is a camera that can shoot moving images, for example, and is installed at a position where an outsider can be photographed when an outsider enters the home where the thermoelectric supply device 12 is installed.

  The surveillance camera control device 14 includes an acquisition unit 14A, a storage unit 14B, and a control unit 14C.

  The acquisition unit 14A acquires the power consumption of the power device group 16 detected by the power meter 12C of the thermoelectric supply device 12 and the hot water consumption of the hot water supply device group 18 detected by the hot water supply meter 12D, and the storage unit 14B. It memorizes sequentially. Thereby, the memory | storage part 14B memorize | stores the log | history of electric power consumption and hot water supply consumption. Moreover, in this embodiment, the case where the power consumption of the power equipment group 16 detected by the power meter 12C of the thermoelectric supply device 12 and the hot water consumption of the hot water supply equipment group 18 detected by the hot water supply meter 12D are described. However, the present invention is not limited to this, and the power consumption and the hot water consumption detected by the wattmeter 12C and the hot water meter 12D in a home where the thermoelectric supply device 12 is not provided may be acquired.

  The control unit 14C controls photographing by the monitoring camera 22 installed in the home based on the power consumption and hot water consumption consumed by the acquisition unit 14A.

  Specifically, the monitoring camera control device 14 includes, for example, a CPU, a ROM, a nonvolatile memory storing a monitoring camera control program described later, a RAM storing data, a communication interface for communicating with an external device, and the like. A computer including a bus or the like for connecting them is included. The communication interface is an interface for wireless communication with an external device such as the smartphone 20. The CPU executes a monitoring camera control process to be described later by reading the monitoring camera control program stored in the nonvolatile memory.

  Next, as an operation of the present embodiment, a monitoring camera control process executed by the monitoring camera control device 14 will be described with reference to a flowchart shown in FIG. The process shown in FIG. 2 is executed when the user operates an operation unit (not shown) to instruct the monitoring camera to start monitoring.

  First, in step S100, the acquisition unit 14A acquires the power consumption from the wattmeter 12C, acquires the hot water supply consumption from the hot water supply meter 12D, and stores it in the storage unit 14B.

  In step S102, the control unit 14C determines whether or not the home where the thermoelectric supply device 12 is installed is away. Specifically, for example, the user can set absence information indicating whether the user is away or at home by operating an operation unit (not shown), and the absence information is stored in the storage unit 14B. . Then, by referring to the absence information stored in the storage unit 14B, it can be determined whether the user is away or at home.

  Or you may make it determine whether it is away based on the log | history of the power consumption and hot water supply consumption memorize | stored in the memory | storage part 14B. For example, it may be determined that the user is away when at least one of power consumption and hot water supply consumption is equal to or less than a predetermined consumption (for example, several tens of minutes to several hours).

  If it is determined that the user is away, the process proceeds to step S104. If it is determined that the user is at home, the determination in step S102 is repeated.

  In step S104, the control unit 14C determines whether or not at least one of the power consumption and the hot water supply consumption is equal to or greater than a predetermined threshold value. If the determination is affirmative, the process proceeds to step S106. Return to step S102.

  In step S106, the control unit 14C instructs the monitoring camera 22 to start photographing. Thereby, the surveillance camera 22 starts photographing and outputs the photographed image to the storage unit 14B. For example, when the storage area for the photographed image is determined in advance and the storage area is full, the storage unit 14B overwrites the latest photographed image on the area where the old photographed image is stored. That is, the storage area for the captured image is a so-called ring buffer.

  In step S108, the control unit 14C transmits warning information indicating that an outsider may have entered the home to the smartphone 20 for display. Thereby, the user can easily recognize that there is a possibility that an outsider has entered while on the go. Note that a captured image may be included in the warning information. Thereby, the user can confirm an outsider easily.

  In step S110, the control unit 14C determines whether or not a shooting stop condition for stopping shooting by the monitoring camera 22 is satisfied. If the determination is affirmative, the process proceeds to step S112. If the determination is negative, the shooting is continued. To do.

  As a case where the photographing stop condition is satisfied, for example, there is a case where an outsider is absent. Specifically, for example, when at least one of the power consumption and the hot water consumption determined to be equal to or greater than the threshold in step S104 is less than the threshold, it is determined that the outsider is absent, It can be determined that the shooting stop condition is satisfied.

  Further, when the user operates the smartphone 20 and instructs to stop shooting, it may be determined that the shooting stop condition is satisfied.

  Further, it may be determined whether or not the user is away from home as in step S102, and when the user is determined to be at home, it may be determined that the shooting stop condition is satisfied.

  In step S112, the control unit 14C instructs the monitoring camera 22 to stop photographing. Thereby, the surveillance camera 22 stops photographing.

  In step S114, the control unit 14C determines whether or not the user has operated an operation unit (not shown) to give an instruction to stop monitoring by the monitoring camera. If the determination is affirmative, this routine is terminated. If the determination is negative. Returns to step S102 and repeats the above process.

  In the present embodiment, the case where both the power consumption amount and the hot water consumption amount are acquired and the photographing of the monitoring camera 22 is controlled has been described. However, either the power consumption amount or the hot water consumption amount is acquired and monitored. You may control imaging | photography of the camera 22. FIG.

  In the present embodiment, it is determined whether or not the user is away in Step S102 and Step S104 is executed when the user is away. However, the process of Step S102 may be omitted. That is, step S104 may be executed after step S100.

  As described above, in this embodiment, since the photographing by the monitoring camera 22 installed in the home is controlled based on at least one of the power consumption and the hot water consumption in the home, the photographing by the monitoring camera 22 is always performed. It is not necessary to perform this, and it is possible to prevent the capacity of the storage unit 14B that stores the captured image from being filled in a short period of time.

  The embodiments of the present invention have been described above, but the present invention is not limited to the above, and it goes without saying that various modifications can be made without departing from the spirit of the present invention. Nor.
