Having determined Yes in step S<b>58 , the external server 50 proceeds to step S<b>59 to wirelessly transmit the locking/unlocking information and flow line information of the second smartphone 70 recorded in the storage to the first smartphone 60 .

When the external server 50 completes the process of step S59 or determines No in steps S52 and S58, the process of the flowchart of FIG. 10 is temporarily terminated.

Next, a flow of processing performed by the first smartphone 60 will be described with reference to FIG. 11 .

In step S60, first smartphone 60 determines whether or not resident P1 has operated a flow line request button included in the operation screen of the owner's key operation application.

Having determined Yes in step S60 , the first smartphone 60 proceeds to step S61 and wirelessly transmits the flow line information request signal generated by the flow line information requesting unit to the external server 50 .

After completing the process of step S<b>61 , the first smartphone 60 proceeds to step S<b>62 and determines whether or not the locking/unlocking information and the flow line information have been received from the external server 50 .

The first smartphone 60 that determines Yes in step S<b>62 proceeds to step S<b>63 , and the display control unit controls the display 61 . Accordingly, the locking/unlocking information and the flow line information received by the first smartphone 60 are displayed on the display 61 . For example, as shown in FIG. 12, the display 61 displays the date and time when the owner P2 unlocked the locking/unlocking device 22 of the building 12 and the date and time when the locking/unlocking device 22 was locked. Also, by operating the touch panel, as shown in FIG. Information (traffic line information) related to the time spent is displayed. Furthermore, although illustration is omitted, when the flow line information received by the first smartphone 60 includes the captured data of the camera 32 , the moving image acquired in the room 18 is displayed on the display 61 . Furthermore, although illustration is omitted, when the flow line information received by first smartphone 60 includes the position information of second smartphone 70 in room 18 , second smartphone 70 (continuously n) Location information is displayed.

As described above, according to the system 10 of the present embodiment, when the first control device 40 wirelessly communicates with the second smartphone 70 possessing a digital key and authenticates the digital key, the first control device 40 locks and unlocks the lock. Switch the device 22 from the locked state to the unlocked state. Therefore, the holder P2 of the second smart phone 70 can enter the building 12 . When the possessor P2 enters the building 12 after the locking/unlocking device 22 is unlocked, the motion sensors 28, 31, 35, and 39 installed in the building 12 and the camera 32 are used to detect the inside of the building 12. A flow line of the holder P2 is detected. Therefore, the resident P1 of the building 12 can recognize the behavior of the owner P2 by checking the detected flow line using the first smartphone 60 .

For example, as shown in FIG. 13, when the owner P2 ignores the promise with the resident P1 and enters the room 19, the resident P1 can recognize the action of the owner P2.

Further, for example, if the photographed data acquired by the camera 32 includes an image of the holder P2 opening the drawer of the wardrobe 17A, the resident P1 can recognize the action of the holder P2.

For example, based on the position information of the second smartphone 70 in the room 18 calculated based on the radio waves transmitted from the three or more radio wave transmitters 36, it becomes clear that the owner P2 has approached the refrigerator 18B. In this case, the resident P1 can recognize the action of the possessor P2.

Possessor P2, who enters building 12 with permission from resident P1 in this way, may act unexpectedly by resident P1. However, resident P1 can recognize this. Therefore, in such a case, the resident P1 can warn or warn the owner P2. Therefore, compared with the case where the resident P1 cannot recognize the behavior of the possessor P2, the resident P1 is more likely to have a motivation to introduce the system 10 into his/her building 12 .

Furthermore, the human sensors 31, 35, and 39 are built in home electric appliances (the air conditioner 30, the air conditioner 34, and the lighting device 38) installed in the building 12 in advance. Therefore, the system 10 can be constructed at low cost.

The in-building flow line detection system according to the embodiment has been described above, but the design of the in-building flow line detection system can be changed as appropriate without departing from the gist of the present invention.

For example, when the second smartphone 70 can recognize its own location information using the GPS signal of the Global Positioning System, the location information of the second smartphone 70 transmitted (wirelessly transmitted) by the second smartphone 70 is The second control device 45 may receive it as flow line information. In this case, the building 12 may or may not be equipped with the sensor group.

If the second smartphone 70 includes a 3-axis gyro sensor (3-axis sensor), the detection result of the 3-axis gyro sensor may be used as flow line information. In this case, the flow line information includes the flow line information of the holder P2 in the vertical direction. Therefore, for example, when the building 12 is a two-story building and the owner P2 moves up the stairs of the building 12, the resident P1 refers to the detected flow line information to determine whether the owner P2 is inside the building 12. can be recognized as moving up and down.

The mobile terminal that receives the digital key from external server 50 may be different from second smartphone 70 . For example, a tablet computer can be used as the mobile terminal.

An information terminal that receives locking/unlocking information and flow line information from external server 50 may be different from first smartphone 60 . For example, a personal computer installed in the building 12 and capable of communicating with the external server 50 via the Internet can be used as the information terminal.

The locking/unlocking device 22 may be provided on a door (not shown) that opens and closes the back door provided on the outer wall 13 of the building 12 .
