Specifically, the terminal instruction notification unit 274 becomes the second terminal communication unit 25 of the user terminal 2 and the second lock communication unit 12 of the lock opening / closing device 1 after the terminal request notification unit 273 notifies the standby request. Is connected, the unlocking instruction including the UUID is notified to the lock opening / closing device 1 via the second terminal communication unit 25.

The terminal instruction notification unit 274 may notify the lock opening / closing device 1 of the unlocking instruction via the control device 4. In this case, the terminal instruction notification unit 274 passes through the control device 4 after the terminal request notification unit 273 notifies the standby request, that is, on condition that the user who owns the user terminal 2 is in a predetermined area. Then, the unlocking instruction may be notified to the lock opening / closing device 1. In the terminal instruction notification unit 274, for example, after the terminal request notification unit 273 notifies the standby request, the second terminal communication unit 25 of the user terminal 2 receives the radio wave of the second lock communication unit 12 of the lock opening / closing device 1. In this case, the unlocking instruction may be notified to the lock opening / closing device 1 by notifying the control device 4 of the unlocking instruction including the UUID via the first terminal communication unit 24.

FIG. 4 is a diagram for explaining the timing at which the standby request and the unlocking instruction are notified. The position P1 shown in FIG. 4 is the position where the user holding the user terminal 2 exists, and it is assumed that the user is moving on the road in the direction of the arrow. The position P2 is the existing position of the lock opening / closing device 1. The area R1 is a preset area, and the area is wider than the area R2.

[Configuration of control device 4]
Subsequently, the configuration of the control device 4 will be described. FIG. 6 is a diagram showing the configuration of the control device 4. The control device 4 has a device communication unit 41, a device storage unit 42, and a control unit 43.

The device communication unit 41 is a communication module that communicates with the lock / close device 1 via the user terminal 2 and the relay device 3. The device storage unit 42 is a storage medium such as a ROM, RAM, and a hard disk. The device storage unit 42 stores a program executed by the control unit 43. The device storage unit 42 stores a setting information management database that stores setting information.

FIG. 7 is a diagram showing a configuration of a setting information management database. As shown in FIG. 7, the setting information management database identifies the user identification information corresponding to the user who uses the user terminal 2, the device identification information that identifies the relay device 3, and the lock / close device 1 as the setting information. It is stored in association with the lock identification information.

Returning to FIG. 6, the control unit 43 is, for example, a CPU. The control unit 43 controls the function related to the control device 4 by executing the program stored in the device storage unit 42. By executing the program, the control unit 43 functions as an acquisition unit 431, a determination unit 432, and a device notification unit 433.

When the device notification unit 433 receives the standby request from the user terminal 2 via the device communication unit 41, the device notification unit 433 notifies the lock / close device 1 associated with the user who uses the user terminal 2 of the standby instruction. , The communication mode of the second lock communication unit 12 of the lock opening / closing device 1 is switched to the standby mode. Specifically, when the device notification unit 433 receives the standby request from the user terminal 2, the received standby request includes a standby instruction instructing to switch to a state in which communication with the user terminal 2 is possible. Notifies the lock opening / closing device 1 indicated by the lock identification information stored in the setting information management database in association with the user identification information.

More specifically, when the device notification unit 433 receives the standby request from the user terminal 2, the lock identification information stored in the setting information management database in association with the user identification information included in the standby request. The standby instruction including the above is notified to the relay device 3 indicated by the device identification information stored in the setting information management database in association with the user identification information.

The device notification unit 433 switches the communication mode of the second lock communication unit 12 of the lock opening / closing device 1 to the standby mode, and then when the user enters the house, the second lock communication unit 12 of the lock opening / closing device 1 The communication mode may be switched to hibernation mode. Specifically, the device notification unit 433 may notify the lock / close device 1 of a pause instruction instructing to switch to a state in which communication with the user terminal 2 is impossible, provided that the user is in the house.

More specifically, first, the acquisition unit 431 acquires the position information indicating the existence position of the user terminal 2 from the user terminal 2. The determination unit 432 determines whether or not the user is in the house based on the existence position of the user terminal 2 indicated by the position information acquired by the acquisition unit 431. The determination unit 432 allows the user to use the user terminal 2 in the home, for example, based on whether or not the position of the user terminal 2 is included in the home area including the lock / close device 1 (for example, within a radius of 10 meters from the lock / close device 1). Determine if you are in. Then, when the determination unit 432 determines that the user is in the house, the device notification unit 433 notifies the lock opening / closing device 1 of a pause instruction instructing the switch to the pause mode. By doing so, the control device 4 can reduce the power consumption of the lock opening / closing device 1.

By the way, it may not be possible to determine whether or not the user is in the house from the location information. For example, when the user's house is a dwelling unit of a condominium or other condominium, and the route from the entrance of the condominium building to the user's house is indoors, the GPS accuracy deteriorates and whether or not the user is in the house.
