[0018] The invention described in claim 4 In this system, the movement line detection unit detects the movement line of the carrier based on the detection results of the three-axis sensor built into the mobile device. Therefore, the movement line detection unit can detect not only the carrier's horizontal movement line but also their vertical movement line. Therefore, for example, if the carrier moves up the stairs in a building, the resident can recognize that the carrier has moved up and down within the building by referring to the detected movement line.

[0019] Claim 5 The in-building traffic line detection system according to the invention described in Claims 1 to 4In any one of the above-mentioned inventions, three or more radio wave transmitters that transmit radio waves are installed in the building, and the movement path detection unit detects the movement path of the holder within the building based on information regarding the position of the mobile terminal calculated based on the radio waves received by the mobile terminal from each of the radio wave transmitters.

[0020] Claim 5 In the invention described in the above, the location of a mobile device can be determined with high accuracy by using radio waves transmitted from three or more radio wave transmitters installed in a building. Therefore, the movement path detection unit can detect the movement path of the mobile device owner within the building with high accuracy based on information about the location of the mobile device. Therefore, building residents can recognize the behavior of the mobile device owner with high accuracy by referring to the detected movement path.

[0021] Claim 6 The in-building traffic line detection system according to the invention described in Claims 1 to 5 In the invention described in any one of the above, the device further comprises a flow line information transmitting unit that transmits information about the flow line of the holder detected by the flow line detecting unit to an information terminal other than the portable terminal.

[0022] Claim 6 In the invention described in the above, the movement line information, which is information about the movement line of the holder detected by the movement line detection unit, is transmitted to an information terminal separate from the mobile terminal by the movement line information transmission unit, so that the residents of the building can recognize the movement of the holder by looking at the information terminal. [Effects of the Invention]

[0023] As described above, the in-building flow line detection system according to the present invention has the excellent effect of enabling building residents to recognize the behavior of people who have entered the building using a digital key. [Brief explanation of the drawings]

[0026] The building 12 shown in Figures 1 and 2 is a one-story house. A resident P1 shown in Figure 1 lives in the building 12. The building 12 has an exterior wall 13 that is approximately rectangular in plan view (cross-sectional shape) and a partition wall 14 that divides the interior space into four rooms 16, 17, 18, and 19. As shown in Figure 2, a chest of drawers 17A is installed in room 17. Furthermore, a desk 18A and a refrigerator 18B are installed in room 18.

[0027] An opening 13A is formed in a part of the exterior wall 13, and an entrance door (door) 21 is provided in this opening 13A so as to be able to open and close. The entrance door 21 is provided with a locking / unlocking device 22 having an electric actuator. The locking / unlocking device 22 is switched between a locked state and an unlocked state by the driving force of the electric actuator. When the entrance door 21 is in the closed position shown by the solid lines in FIGS. 1 and 2 and the locking / unlocking device 22 is set to the locked state, the entrance door 21 is held in the closed position. On the other hand, when the locking / unlocking device 22 is set to the unlocked state, the entrance door 21 can be rotated to the open position shown by the phantom lines in FIG. 1.

[0028] The partition wall 14 is provided with an opening 14A that connects the rooms 16 and 17, an opening 14B that connects the rooms 17 and 18, and an opening 14C that connects the rooms 18 and 19. A first door 24 that opens and closes the opening 14A is provided in the opening 14A, a second door 25 that opens and closes the opening 14B is provided in the opening 14B, and a third door 26 that opens and closes the opening 14C is provided in the opening 14C.

[0029] A human presence sensor (sensor) 28 is provided in room 16. Human presence sensor 28 and human presence sensors 31, 35, and 39, which will be described later, are infrared human presence sensors. However, human presence sensors 28, 31, 35, and 39 may be of a type other than infrared. When a person is present in each of rooms 16, 17, 18, and 19, each of human presence sensors 28, 31, 35, and 39 provided in each room outputs a detection signal.

[0030] An air conditioner (home appliance) 30 is provided in room 17. This air conditioner 30 has a built-in human presence sensor (sensor) 31. When human presence sensor 31 detects the presence of a person in room 17, the air conditioner 30 operates, and when human presence sensor 31 no longer detects the presence of a person in room 17, the air conditioner 30 stops operating. Furthermore, a camera (sensor) 32 is provided in room 17. When human presence sensor 31 detects the presence of a person in room 17, the camera 32 performs a photographing operation, and when human presence sensor 31 no longer detects the presence of a person in room 17, the camera 32 stops photographing.

[0031] An air conditioner (home appliance) 34 is installed in room 18. This air conditioner 34 has a built-in human presence sensor (sensor) 35. When the human presence sensor 35 detects the presence of a person in room 18, the air conditioner 34 operates, and when the human presence sensor 35 no longer detects the presence of a person in room 18, the air conditioner 34 stops operating. Furthermore, three radio wave transmitters 36 are installed in room 18. When the human presence sensor 35 detects the presence of a person in room 18, each radio wave transmitter 36 emits radio waves that can be received by a second smartphone 70 located inside room 18.

[0032] A lighting device (home appliance) 38 is provided in the room 19. This lighting device 38 has a built-in motion sensor (sensor) 39. When the motion sensor 39 detects that a person is present in the room 19, the lighting device 38 turns on, and when the motion sensor 39 no longer detects that a person is present in the room 19, the lighting device 38 turns off.

[0033] As shown in FIG. 1, a building 12 is provided with a first control device (unlock control unit) 40 and a second control device 45.

[0034] As shown in Fig. 3, the first control device 40, which is provided near the front door 21 (opening 13A), includes a CPU (Central Processing Unit) (processor) 40A, a ROM (Read Only Memory) 40B, a RAM (Random Access Memory) 40C, a storage 40D, a wireless communication I / F (Interface) 40E, an internal communication I / F 40F, and an input / output I / F 40G. The CPU 40A, ROM 40B, RAM 40C, storage 40D, wireless communication I / F 40E, internal communication I / F 40F, and input / output I / F 40G are connected to each other via an internal bus 40Z so as to be able to communicate with each other. The locking / unlocking device 22 is connected to the first control device 40 (input / output I / F 40G).

[0035] The CPU 40A is a central processing unit that executes various programs and controls each part. The CPU 40A reads programs from the ROM 40B or storage 40D and executes the programs using the RAM 40C as a work area. The CPU 40A controls each component and performs various arithmetic processing in accordance with the programs recorded in the ROM 40B or storage 40D.

[0036] The ROM 40B stores various programs and various data. The RAM 40C temporarily stores programs or data as a working area. The storage 40D is configured by a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive) and stores various programs and various data.

[0037] The wireless communication I / F 40E is an interface for wireless communication with various devices. For example, the wireless communication I / F 40E is capable of wireless communication with an external server 50, a first smartphone 60, and a second smartphone 70. The wireless communication I / F 40E uses communication standards such as Bluetooth Low Energy (Bluetooth (registered trademark)) and Wi-Fi (registered trademark).

[0038] The internal communication I / F 40F is an interface for connecting to the second control device 45 via the external bus 41. That is, the first control device 40 and the second control device 45 transmit and receive various information to and from each other.

[0039] The input / output I / F 40G is an interface for communicating with the locking / unlocking device 22.

[0040] 4 is a block diagram showing an example of the functional configuration of the first control device 40. The first control device 40 has, as its functional configuration, a digital key acquisition unit 401, a terminal digital key acquisition unit 402, a digital key authentication unit 403, an unlock control unit 404, a lock control unit 405, and a communication control unit 406. The digital key acquisition unit 401, the terminal digital key acquisition unit 402, the digital key authentication unit 403, the unlock control unit 404, the lock control unit 405, and the communication control unit 406 are realized by the CPU 40A reading and executing programs stored in the ROM 40B.

[0041] When a digital key transmission request is wirelessly transmitted to the external server 50 via the wireless communication I / F 40E, the digital key acquisition unit 401 downloads and acquires the digital key from the external server 50 via wireless communication.

[0042] The terminal digital key acquisition unit 402 acquires digital keys from the first smartphone 60 and the second smartphone 70 via a BLE (Bluetooth Low Energy) link established between the first smartphone 60 and the second smartphone 70.

[0043] The digital key authentication unit 403 authenticates the digital key using the digital key acquired from the external server 50 by the digital key acquisition unit 401 and the digital keys acquired from the first smartphone 60 and the second smartphone 70 by the terminal digital key acquisition unit 402.

[0044] The unlocking control unit 404 transitions the locking / unlocking device 22 to an unlocked state when an unlocking instruction, which will be described later, is received from the first smartphone 60 or the second smartphone 70.

[0045] When the lock control unit 405 receives a lock instruction, which will be described later, from the first smartphone 60 or the second smartphone 70, the lock control unit 405 causes the locking / unlocking device 22 to transition to a locked state.

[0046] The communication control unit 406 has a function of transmitting unlock information, which includes information on the ID of the terminal that executed the unlock instruction and the time when the unlock instruction was executed, and lock information, which includes information on the ID of the terminal that executed the lock instruction and the time when the lock instruction was executed, to the second control device 45 via the external bus 41. The unlock information and lock information may be collectively referred to as "lock / unlock information."

[0047] The second control device 45 has the same hardware configuration as the first control device 40. That is, the second control device 45 also includes a CPU, ROM, RAM, storage, a wireless communication I / F, an internal communication I / F and an input / output I / F, and an internal bus. The second control device 45 (input / output I / F) is connected to the human presence sensor 28, the air conditioner 30 (human presence sensor 31), the camera 32, the air conditioner 34 (human presence sensor 35), the radio wave transmitter 36, and the lighting device 38 (human presence sensor 39).

[0048] 5 is a block diagram showing an example of the functional configuration of second control device 45. Second control device 45 has, as its functional configuration, an electrical appliance control unit 451, a flow line information collection unit 452, and a communication control unit 453. The electrical appliance control unit 451, the flow line information collection unit 452, and the communication control unit 453 are realized by the CPU reading and executing programs stored in the ROM.

[0049] The electrical appliance control unit 451 operates the air conditioner 30 and the camera 32 when it receives a detection signal output by the human sensor 31. On the other hand, it stops the operation of the air conditioner 30 and the camera 32 when the human sensor 31 stops outputting a detection signal. Furthermore, the electrical appliance control unit 451 operates the air conditioner 34 and the radio wave transmitter 36 when it receives a detection signal output by the human sensor 35. On the other hand, it stops the operation of the air conditioner 34 and the radio wave transmitter 36 when the human sensor 35 stops transmitting a detection signal. Furthermore, the electrical appliance control unit 451 operates the lighting device 38 when it receives a detection signal output by the human sensor 39. On the other hand, it stops the operation of the human sensor 39 when the human sensor 39 stops transmitting a detection signal.

[0050] The flow line information collecting unit 452 collects flow line information, which is information relating to the flow lines of people within the building 12, detected by the human sensors 28, 31, 35, and 39 and the camera 32 as will be described later.

[0051] The communication control unit 453 transmits the flow line information collected by the flow line information collection unit 452 and the locking / unlocking information received from the first control device 40 to the external server 50 using the wireless communication I / F.

[0052] The external server 50 includes, as its hardware configuration, a CPU, a ROM, a RAM, a storage, a wireless communication I / F, an internal communication I / F and an input / output I / F, and an internal bus.

[0053] 6 is a block diagram showing an example of the functional configuration of the external server 50. The external server 50 has, as its functional configuration, a digital key generation unit 501 and a communication control unit (traffic line information transmission unit) 502. The digital key generation unit 501 and the communication control unit 502 are realized by a CPU reading and executing a program stored in a ROM.

[0054] The digital key generation unit 501 generates a digital key for locking and unlocking the locking / unlocking device 22 when it receives a request from the first smartphone 60. Furthermore, the digital key generation unit 501 generates a digital key when it receives a request from the second smartphone 70 carried by the owner P2 who has been permitted to enter the building 12 by the resident P1. The digital key generation unit 501 changes the specifications (contents) of the digital key it generates at predetermined intervals. Furthermore, the digital key generation unit 501 can set an expiration date for the digital key it generates. In other words, the digital key generation unit 501 can generate a digital key that is valid only during a specific time period on a specific day.

[0055] Furthermore, when the digital key generation unit 501 receives a request to send a digital key from the first control device 40 (digital key acquisition unit 401), it generates a digital key.

[0056] The communication control unit 502 wirelessly transmits the digital key generated by the digital key generation unit 501 to the device that requested the generation of the digital key (the first control device 40, the first smartphone 60, or the second smartphone 70) using the wireless communication I / F. Furthermore, the communication control unit 502 receives the traffic line information and locking / unlocking information wirelessly transmitted from the second control device 45 using the wireless communication I / F.

[0057] 1 is provided with a display 61 having a touch panel. The first smartphone 60 has, as its hardware configuration, a CPU, ROM, RAM, storage, a wireless communication I / F, an internal communication I / F, an input / output I / F, and an internal bus. An owner key-operated application downloaded from an external server 50 is installed on the first smartphone 60.

[0058] The first smartphone 60 has, as its functional configuration, a display control unit, a digital key acquisition unit, a digital key transmission unit, an unlock request unit, a lock request unit, and a flow line information request unit. The display control unit, the digital key acquisition unit, the digital key transmission unit, the unlock request unit, the lock request unit, and the flow line information request unit of the first smartphone 60 are realized by the CPU reading and executing a program (for example, an owner key operation application) stored in the ROM.

[0059] The display control unit controls the display 61. That is, for example, the display control unit causes the display 61 to display information that the first smartphone 60 has received from another information communication device (for example, the external server 50). Furthermore, when the owner key operation application is executed, the display control unit causes the display 61 to display an operation screen of the owner key operation application.

[0060] The digital key acquisition unit downloads the digital key transmitted by the external server 50 via the wireless communication I / F.

[0061] The digital key transmitting unit transmits the downloaded digital key to the first control device 40 via the wireless communication I / F.

[0062] When the unlock button included in the operation screen of the owner key operation application is operated (when the resident P1 touches it with his / her hand), the unlock request unit generates an unlock request signal and transmits it to the first control device 40 via the wireless communication I / F.

[0063] When a lock button included in the operation screen of the owner key operation application is operated, the lock request unit generates a lock request signal and transmits it to the first control device 40 via the wireless communication I / F.

[0064] When a flow line information acquisition button included in the operation screen of the owner key operation application is operated, the flow line information request unit generates a flow line information request signal and transmits it to the external server 50 via the wireless communication I / F.

[0065] 1 is provided with a touch panel 71. The second smartphone 70 has a hardware configuration including a CPU, ROM, RAM, storage, a wireless communication I / F, an internal communication I / F, an input / output I / F, and an internal bus. A guest key operation application downloaded from the external server 50 is installed on the second smartphone 70.

[0066] The second smartphone 70 has, as its functional configuration, a display control unit, a digital key acquisition unit, a digital key transmission unit, an unlock request unit, a lock request unit, and a position calculation unit. The display control unit, the digital key acquisition unit, the digital key transmission unit, the unlock request unit, the lock request unit, and the position calculation unit of the second smartphone 70 are realized by the CPU reading and executing a program (for example, a guest key operation application) stored in the ROM.

[0067] The functions of the display control unit, digital key acquisition unit, digital key transmission unit, unlock request unit, and lock request unit of the second smartphone 70 are identical to the functions of the display control unit, digital key acquisition unit, digital key transmission unit, unlock request unit, and lock request unit of the first smartphone 60, respectively.

[0068] When the wireless communication I / F of the second smartphone 70 receives radio waves transmitted from three radio wave transmitters 36 installed in the room 18, the position calculation unit calculates the distance between each radio wave transmitter 36 and the second smartphone 70 based on the received radio waves, and further calculates the position of the second smartphone 70 based on the three distances. Note that the number of radio wave transmitters 36 installed in the room 18 may be any number equal to or greater than three. When the position of the second smartphone 70 is calculated based on radio waves received from three or more radio wave transmitters 36 in this way, the position of the second smartphone 70 can be determined with high accuracy. Furthermore, the position calculation unit transmits information related to the calculated position of the second smartphone 70 to the second control device 45 via the wireless communication I / F.

[0069] Next, the flow of processing performed by the first control device 40, the second control device 45, the external server 50, the first smartphone 60, and the second smartphone 70 will be described with reference to the flowcharts of FIGS. 7 to 11. In the following description, it is assumed that the resident P1 is outside the building 12, and the holder P2 is a delivery person authorized by the resident P1 to enter the building 12. It is also assumed that the resident P1 and the holder P2 have agreed that the holder P2 will place a specified package (not shown) on a desk 18A installed in the room 18 and, after placing it, will promptly move outside the building 12. It is also assumed that the locking / unlocking device 22 is in a locked state when the holder P2 arrives at the building 12.

[0070] First, the flow of processing performed by the second smartphone 70 will be described with reference to FIG. 7. A digital key has already been downloaded to the second smartphone 70. This digital key is valid only during a specific time period on a specific day. Hereinafter, this time period will be referred to as the "designated time period." Furthermore, a guest key operation application is running on the second smartphone 70.

[0071] In step S10, the second smartphone 70 determines whether the current time is included in the designated time period. In this case, the second smartphone 70 determines Yes in step S10 and proceeds to step S11.

[0072] In step S11, the second smartphone 70 determines whether a BLE link has been established with the first control device 40.

[0073] If the second smartphone 70 determines Yes in step S11, the process proceeds to step S12, where the digital key transmission unit wirelessly transmits the downloaded digital key to the first control device 40. After completing the process of step S12, the second smartphone 70 proceeds to step S13.

[0074] As described above, the digital key authentication unit 403 of the first control device 40 that has received the digital key from the second smartphone 70 determines whether or not to authenticate the digital key, using the digital key downloaded from the external server 50 and the digital key received from the second smartphone 70. As will be described further below, the first control device 40 that has authenticated the digital key wirelessly transmits an authentication signal to the second smartphone 70. If the second smartphone 70 determines Yes in step S13, it proceeds to step S14 and determines whether or not the owner P2 has operated the unlock button included in the operation screen of the guest key operation application.

[0075] If the second smartphone 70 determines "Yes" in step S14, the process proceeds to step S15, where the unlocking request unit generates an unlocking request signal and wirelessly transmits the generated unlocking request signal to the first control device 40. That is, the second smartphone 70 issues an unlocking instruction to the first control device 40.

[0076] When the process of step S15 is executed, the locking / unlocking device 22 is unlocked in step S36 of Fig. 8, which will be described later. This allows the holder P2 to move the front door 21 to the open position and enter the room 16. Furthermore, the holder P2 can move to the room 17 by opening the first door 24, and can move to the room 18 by opening the second door 25.

[0077] For example, when the owner P2 moves to the room 18 along the route PS indicated by the dashed line in Fig. 2, the second smartphone 70 receives radio waves from each radio wave transmitter 36. Therefore, in this case, the second smartphone 70 determines "Yes" in step S16 and proceeds to step S17.

[0078] In step S17, the position calculation unit of the second smartphone 70 calculates the position of the second smartphone 70 and transmits the calculated position information to the second control device 45 by wireless.

[0079] After completing the process of step S17, the second smartphone 70 proceeds to step S18 and performs the same process as in step S11.

[0080] After completing the process of step S18, the second smartphone 70 proceeds to step S19 and determines whether or not the lock button included in the operation screen of the guest key operation application has been operated.

[0081] If the second smartphone 70 determines "Yes" in step S19, the process proceeds to step S20, where the lock request unit generates a lock request signal and transmits it to the first control device 40 by wireless.

[0082] When the second smartphone 70 has finished the process of step S20 or when it determines No in steps S10, 11, 13, 14, and 19, it temporarily ends the process of the flowchart in FIG.

[0083] Next, the flow of processing performed by the first control device 40 will be described with reference to FIG.

[0084] In step S30, the first control device 40 performs the same process as in step S11.

[0085] After completing the process of step S30, the first control device 40 proceeds to step S31 and determines whether or not a digital key has been received from the second smartphone 70.

[0086] If the first control device 40 determines "Yes" in step S31, the process proceeds to step S32, where the digital key acquisition unit 401 issues a request to the external server 50 to transmit the digital key.

[0087] After completing the process of step S32, the first control device 40 proceeds to step S33 and determines whether or not the digital key has been downloaded from the external server 50.

[0088] If the first control device 40 determines "Yes" in step S33, the process proceeds to step S34, where the digital key authentication unit 403 authenticates the digital key received from the second smartphone 70 using the digital key downloaded from the external server 50.

[0089] If the first control device 40 determines "Yes" in step S34, it transmits an authentication signal to the second smartphone 70, and then proceeds to step S35 to determine whether an unlocking request signal has been received from the second smartphone 70.

[0090] If the first control device 40 determines "Yes" in step S35, the process proceeds to step S36, where the unlocking control unit 404 controls the electric actuator of the locking / unlocking device 22 to transition the locking / unlocking device 22 to an unlocked state. Furthermore, the communication control unit 406 transmits unlocking information based on the unlocking instruction from the second smartphone 70 to the second control device 45.

[0091] After completing the process of step S36, the first control device 40 proceeds to step S37 and performs the same process as in S30. For example, when the owner P2 of the second smartphone 70 approaches the door 21 again, the first control device 40 determines Yes in step S37.

[0092] If the first control device 40 determines "Yes" in step S37, the process proceeds to step S38, where it determines whether or not a locking request signal has been received from the second smartphone 70.

[0093] If the first control device 40 determines "Yes" in step S38, the process proceeds to step S39, where the lock control unit 405 controls the electric actuator of the locking / unlocking device 22 to transition the locking / unlocking device 22 to the locked state. Furthermore, the communication control unit 406 transmits locking information based on the locking instruction from the second smartphone 70 to the second control device 45.

[0094] When the first control device 40 has completed the process of step S39 or when it has determined No in steps S30, S31, S33, S34, and S38, it temporarily ends the process of the flowchart in FIG.

[0095] Next, the flow of processing performed by the second control device 45 will be described with reference to FIG.

[0096] In step S40, the second control device 45 determines whether unlocking information has been received from the first control device 40.

[0097] If the second control device 45 determines "Yes" in step S40, the process proceeds to step S41, where the communication control unit 406 wirelessly transmits unlocking information to the external server 50.

[0098] After completing the processing of step S41, the second control device 45 proceeds to step S42 and determines whether or not it has received a detection signal from any of the human sensors 28, 31, 35, and 39. For example, when the holder P2 is in the room 17, the second control device 45 receives a detection signal from the human sensor 31 and determines Yes in step S42.

[0099] If the second control device 45 determines "Yes" in step S42, it proceeds to step S43 and controls the home appliances in the same room as the human sensor for which the determination "Yes" in step S42 was made. For example, when the owner P2 is in room 17, the second control device 45 operates the air conditioner 30 and the camera 32.

[0100] After completing the processing of step S43, the second control device 45 proceeds to step S44, where the communication control unit 453 wirelessly transmits the flow line information to the external server 50. For example, when the holder P2 is in room 17, the detection signal of the human presence sensor 31 and the image data captured by the camera 32 are transmitted to the external server 50 as flow line information. When the holder P2 is in room 18, information regarding the position of the second smartphone 70 calculated based on the detection signal of the human presence sensor 35 and the radio waves of the radio wave transmitter 36 is transmitted to the external server 50 as flow line information. When the holder P2 is in room 19, the detection signal of the human presence sensor 39 is transmitted to the external server 50 as flow line information.

[0101] After completing the process of step S44, the second control device 45 proceeds to step S45 and determines whether locking information has been received from the first control device 40 or not.

[0102] If the second control device 45 determines "Yes" in step S45, the process proceeds to step S46, where the communication control unit 453 wirelessly transmits the locking information to the external server 50.

[0103] When the second control device 45 has completed the process of step S46, or when it has determined No in steps S40 and S42, it temporarily ends the process of the flowchart in FIG.

[0104] Next, the flow of processing performed by the external server 50 will be described with reference to FIG.

[0105] In step S50, the external server 50 determines whether or not a request to transmit a digital key has been received from the first control device 40.

[0106] If the external server 50 determines "Yes" in step S50, the process proceeds to step S51, where the communication control unit 502 wirelessly transmits the digital key generated by the digital key generation unit 501 to the first control device 40.

[0107] After completing the process of step S51, the external server 50 proceeds to step S52 and determines whether unlocking information has been received from the second control device 45 or not.

[0108] If the external server 50 determines "Yes" in step S52, the process proceeds to step S53, where the external server 50 records the unlocking information in association with the ID information of the second smartphone 70 in the storage of the external server 50.

[0109] After completing the process of step S53, the external server 50 proceeds to step S54 and determines whether or not flow line information has been received from the second control device 45.

[0110] If the external server 50 determines "Yes" in step S54, the process proceeds to step S55, where it records the flow line information in association with the ID information of the second smartphone 70 in the storage.

[0111] After completing the process of step S55, the external server 50 proceeds to step S56 and determines whether lock information has been received from the second control device 45 or not.

[0112] If the external server 50 determines "Yes" in step S56, the process proceeds to step S57, where it records the locking information in association with the ID information of the second smartphone 70 in the storage.

[0113] After completing the process of step S57, the external server 50 proceeds to step S58 and determines whether or not a flow line information request signal has been received from the flow line information request unit of the first smartphone 60.

[0114] If the external server 50 determines "Yes" in step S58, the process proceeds to step S59, where it wirelessly transmits to the first smartphone 60 the locking / unlocking information and the flow line information of the second smartphone 70 that are recorded in the storage.

[0115] When the external server 50 has completed the process of step S59, or when it determines No in steps S52 and S58, it temporarily ends the process of the flowchart in FIG.

[0116] Next, the flow of processing performed by the first smartphone 60 will be described with reference to FIG.

[0117] In step S60, the first smartphone 60 determines whether the resident P1 has operated a flow line request button included in the operation screen of the owner key operation application.

[0118] If the first smartphone 60 determines "Yes" in step S60, the process proceeds to step S61, where it wirelessly transmits the flow line information request signal generated by the flow line information request unit to the external server 50.

[0119] After completing the process of step S61, the first smartphone 60 proceeds to step S62 and determines whether or not it has received locking / unlocking information and flow line information from the external server 50.

[0120] If the first smartphone 60 determines "Yes" in step S62, the process proceeds to step S63, where the display control unit controls the display 61. As a result, the locking / unlocking information and the flow line information received by the first smartphone 60 are displayed on the display 61. That is, 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 owner P2 locked the locking / unlocking device 22. Furthermore, by operating the touch panel, as shown in FIG. 13, information (flow line information) regarding the time when the owner P2 was in each of the rooms 16, 17, 18, and 19, acquired based on the detection results of the motion sensors 28, 31, 35, and 39, is displayed. Furthermore, although not shown in the figure, if the flow line information received by the first smartphone 60 includes captured data from the camera 32, a video captured in the room 18 is displayed on the display 61. Furthermore, although not shown in the figure, if the traffic flow information received by the first smartphone 60 includes location information of the second smartphone 70 in the room 18, the (continuous) location information of the second smartphone 70 is displayed on the display 61.

[0121] 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 that holds a digital key and authenticates the digital key, the first control device 40 switches the locking / unlocking device 22 from a locked state to an unlocked state. This allows the owner P2 of the second smartphone 70 to enter the building 12. When the owner P2 enters the building 12 after the locking / unlocking device 22 is unlocked, the movement path of the owner P2 within the building 12 is detected using the motion sensors 28, 31, 35, and 39 and the camera 32 installed in the building 12. Therefore, a resident P1 of the building 12 can recognize the behavior of the owner P2 by checking the detected movement path using the first smartphone 60.

[0122] For example, as shown in FIG. 13, if the holder P2 ignores the appointment with the resident P1 and enters the room 19, the resident P1 can recognize the holder P2's behavior.

[0123] Furthermore, for example, if the photographic data acquired by the camera 32 includes an image of the owner P2 opening the drawer of the chest of drawers 17A, the resident P1 can recognize this action of the owner P2.

[0124] Furthermore, if it becomes clear that the owner P2 has approached the refrigerator 18B based on the location information of the second smartphone 70 in the room 18 calculated based on radio waves transmitted from three or more radio wave transmitters 36, the resident P1 can recognize the action of the owner P2.

[0125] In this way, the owner P2 who has entered the building 12 with permission from the resident P1 may behave in a way that the resident P1 did not expect. However, the resident P1 can recognize this. Therefore, in such a case, the resident P1 can warn or caution the owner P2. Therefore, the resident P1 is more likely to be motivated to install the system 10 in his or her own building 12 than if the resident P1 were unable to recognize the owner P2's behavior.

[0126] Furthermore, the motion sensors 31, 35, and 39 are built into home appliances (air conditioner 30, air conditioner 34, and lighting device 38) that are installed in advance in the building 12. Therefore, the system 10 can be constructed inexpensively.

[0127] Although the in-building flow line detection system according to the embodiment has been described above, the in-building flow line detection system can be modified in design as appropriate within the scope of the gist of the present invention.

[0128] For example, if the second smartphone 70 can recognize its own location information using a GPS signal of the Global Positioning System, the location information of the second smartphone 70 transmitted (wirelessly transmitted) by the second smartphone 70 may be received as flow line information by the second control device 45. In this case, the building 12 may or may not be equipped with the above-mentioned sensor group.

[0129] If the second smartphone 70 is equipped with a three-axis gyro sensor (triaxial sensor), the detection results of this three-axis gyro sensor may be used as the movement line information. In this case, the movement line information includes information about the movement line of the owner P2 in the vertical direction. Therefore, for example, if the building 12 is a two-story building and the owner P2 moves up the stairs of the building 12, the resident P1 can recognize that the owner P2 has moved up and down within the building 12 by referring to the detected movement line information.

[0130] The mobile terminal that receives the digital key from the external server 50 may be different from the second smartphone 70. For example, a tablet computer may be used as the mobile terminal.

[0131] The information terminal that receives the locking / unlocking information and the traffic line information from the external server 50 may be different from the first smartphone 60. For example, a personal computer that is installed in the building 12 and can communicate with the external server 50 via the Internet can be used as the information terminal.

[0132] The locking / unlocking device 22 may be provided on a door (not shown) that opens and closes a service door provided on the outer wall 13 of the building 12. [Explanation of symbols]
