Description

[Technical Field]

[0001] The present invention relates to a building entry / exit control system. [Background technology]

[0002] Patent Document 1 listed below discloses a locking / unlocking system that can lock and unlock a locking / unlocking device (door lock device) provided on a vehicle door using a digital key downloaded to a mobile terminal such as a smartphone.

[0003] Here, assume that this locking / unlocking system is applied to a locking / unlocking device installed on a building door. In this case, a person (e.g., a daycare service provider) authorized by a resident of the building to enter the building can lock or unlock the door locking / unlocking device using a mobile terminal. Therefore, in this case, only one person authorized by the resident can enter the building when only that person, who is a target resident, is present. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2020-197099 Summary of the Invention [Problem to be solved by the invention]

[0005] Those who enter the building may behave in ways that are unexpected by the residents.

[0006] In consideration of the above, the present invention aims to provide a building entry / exit control system that can reduce the risk of people other than residents who enter a building using a digital key engaging in behavior that makes residents feel uneasy. [Means for solving the problem]

[0007] The building entry / exit control system according to claim 1 includes a person detection unit that detects people inside a building, a digital key authentication unit that determines whether to authenticate the digital key when wirelessly communicating with a mobile terminal that has received the digital key from a server, and an unlocking control unit that unlocks a locking / unlocking device for a door that opens and closes an opening in an exterior wall of the building when the digital key authentication unit authenticates the digital key and the person detection unit detects only registered people. the person detection unit detects a person in the building based on data acquired by a sensor installed in the building, the sensor being a camera, the person detection unit detects the target person based on image data acquired by the camera, and the system includes a human presence sensor capable of detecting a person in the building, the camera performs a photographing operation when the human presence sensor detects a person, and a transmitting device that transmits the image data acquired by the camera to an information terminal other than the mobile terminal, and the information terminal is capable of wirelessly transmitting an emergency signal to a predetermined receiving device. .

[0008] In the building entry / exit control system described in claim 1, when the digital key authentication unit that wirelessly communicates with the mobile device that received the digital key authenticates the digital key and the person detection unit detects only registered individuals, the unlocking control unit unlocks the locking / unlocking device. Therefore, the owner of the mobile device can enter a building where only the registered individuals are present. On the other hand, if the building resident is not present in the building, the owner of the mobile device cannot enter the building using the digital key. This reduces the risk that the owner of the mobile device who is not a resident will engage in behavior that makes the resident feel uneasy.

[0010] Claim 1 In the invention described in the above, the person detection unit detects people in a building based on data acquired by a sensor installed in the building. Therefore, the person detection unit can accurately detect people in the building.

[0012] Claim 1 In the invention described in the item (1), the person detection section can more accurately detect people in a building.

[0014] Claim 1 In the invention described in [2], the camera takes a photograph when the motion sensor detects a person. Therefore, there is a possibility that the owner of the mobile device who enters the building will be photographed by the camera. Therefore, there is less chance that the owner will take actions that make the residents feel uneasy.

[0016] Claim 1In the invention described in the above, even if residents other than the target person are outside the building, they can recognize the behavior of the owner by looking at the information terminal.

[0018] Claim 1 In the invention described in the above, the information terminal can wirelessly transmit an emergency signal to a predetermined receiving device. Therefore, for example, a resident other than the target person can view the image data transmitted to the information terminal and, upon recognizing that the owner has engaged in suspicious behavior, can cause the information terminal to transmit an emergency signal. For example, if the receiving device is installed in a security company's building, the security company can recognize that a problem has occurred in the building. [Effects of the Invention]

[0019] As described above, the building entry / exit control system of the present invention has the excellent effect of reducing the risk that people other than residents who enter the building using a digital key will engage in behavior that makes the residents feel uneasy.

[0021] An embodiment of a building entry / exit control system 10 (hereinafter referred to as the system 10) according to the present invention will be described below with reference to the drawings. As shown in FIG. 1, the system 10 of this embodiment includes a building 12 (locking / unlocking device 22, motion sensors 28, 31, 35, 39, camera 32, first control device 40, and second control device 45), an external server (server) (transmitting device) 50, a first smartphone (mobile terminal) (information terminal) 60, and a second smartphone (mobile terminal) 70. A family lives in the building 12. This family includes a recipient (subject) P1A (see FIG. 2) who receives day care services (described later) and a relative P1B (see FIG. 1) of the recipient P1A. As shown in FIG. 1, the first smartphone 60 is owned by the relative P1B, and the second smartphone 70 is owned by an owner P2. The owner P2 is a staff member of a day care service provider who has been authorized by the recipient P1A and the relative P1B to enter the building 12. At a facility (not shown) of the day care service provider, customers of the day care service provider receive various day care services. The customer, a recipient P1A, has difficulty walking on his or her own and lies on a nursing bed 20 installed in a third room 18 of a building 12 at certain times of the day. The control method for the locking / unlocking device 22 of the system 10 using a digital key described below is one example, and the control method disclosed in Japanese Patent Application Laid-Open No. 2020-197099 may also be used.

[0022] 1 and 2 is a one-story house. 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 a first room 16, a second room 17, a third room 18, and a fourth room 19.

[0023] An opening 13A is formed in a portion of the exterior wall 13, and an entrance door (door) 21 is provided in this opening 13A so that it can be opened and closed. 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 put into the locked state, the entrance door 21 is held in the closed position. On the other hand, when the locking / unlocking device 22 is put into the unlocked state, the entrance door 21 can be rotated to the open position shown by the phantom lines in FIG. 2. As will be described later, the locking / unlocking device 22 is locked and unlocked using a digital key. Furthermore, the locking / unlocking device 22 can also be locked and unlocked by manual operation by a person inside the building 12.

[0024] 2, an opening 13B is formed in another part of the outer wall 13, and a door 23 is provided in this opening 13B so as to be able to open and close. A locking / unlocking device (not shown) is provided in the door 23. This locking / unlocking device is switched between a locked state and an unlocked state by metal keys (not shown) owned by the person to be provided P1A and the relative P1B, respectively.

[0025] Furthermore, an operation device 13C for a call bell system is provided near the opening 13A on the outer surface of the partition wall 14. The operation device 13C has an operation button and a speaker (both not shown). When the operation button of the operation device 13C is operated, a speaker (not shown) provided inside the building 12 emits a specific sound. Therefore, anyone inside the building 12 can recognize that someone has visited the building 12. Furthermore, a voice input device (not shown) is provided inside the building 12. When someone inside the building 12 speaks into the voice input device, this voice is output from the speaker of the operation device 13C. Therefore, when a person inside the building 12 speaks into the voice input device after the operation button of the operation device 13C is operated, the person who operated the operation button can recognize that someone is inside the building 12.

[0026] The partition wall 14 is provided with an opening 14A connecting the first room 16 and the second room 17, an opening 14B connecting the second room 17 and the third room 18, and an opening 14C connecting the third room 18 and the fourth room 19. A first door 24 for opening and closing the opening 14A is provided in the opening 14A, a second door 25 for opening and closing the opening 14B is provided in the opening 14B, and a third door 26 for opening and closing the opening 14C is provided in the opening 14C.

[0027] A motion sensor 28 is provided in the first room 16, a motion sensor 31 is provided in the second room 17, a motion sensor 35 is provided in the third room 18, and a motion sensor 39 is provided in the fourth room 19. Motion sensors 28, 31, 35, and 39 are infrared motion sensors. However, motion sensors 28, 31, 35, and 39 may be motion sensors of a type other than infrared. When a person is present in the first room 16, motion sensor 28 outputs a detection signal. Similarly, when a person is present in the second room 17, motion sensor 31 outputs a detection signal, when a person is present in the third room 18, motion sensor 35 outputs a detection signal, and when a person is present in the fourth room 19, motion sensor 39 outputs a detection signal.

[0028] A nursing care bed 20 is installed in the third room 18. A camera 32 is provided in the third room 18. The camera 32 is capable of capturing an image of a subject located in the third room 18. This subject includes, for example, a person in the third room 18 and the nursing care bed 20. Furthermore, when a motion sensor 35 detects that a person is present in the third room 18, the camera 32 performs a capturing operation, and when the motion sensor 35 no longer detects that a person is present in the third room 18, the camera 32 stops capturing an image.

[0029] As shown in FIG. 1, the building 12 is provided with a first control device 40 and a second control device 45 .

[0030] 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).

[0031] 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.

[0032] 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.

[0033] 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).

[0034] 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.

[0035] The input / output I / F 40G is an interface for communicating with various devices (for example, the locking / unlocking device 22).

[0036] 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.

[0037] 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.

[0038] The terminal digital key acquisition unit 402 acquires a digital key from at least one of 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 and at least one of the first smartphone 60 and the second smartphone 70.

[0039] 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 key acquired from at least one of the first smartphone 60 and the second smartphone 70 by the terminal digital key acquisition unit 402.

[0040] The unlocking control unit 404 transitions the locking / unlocking device 22 to the unlocked state when it receives an unlocking instruction, which will be described later, from the first smartphone 60. Furthermore, the unlocking control unit 404 transitions the locking / unlocking device 22 to the unlocked state when it receives an unlocking instruction from the second smartphone 70 before the locking / unlocking device 22 is locked by the second smartphone 70 and also receives information from the second control device 45 that "the only person present in the third room 18 is the person to be provided P1A." Furthermore, the unlocking control unit 404 transitions the locking / unlocking device 22 to the unlocked state when it receives an unlocking instruction from the second smartphone 70 after the locking / unlocking device 22 is locked by the second smartphone 70 during the designated time period, which will be described later.

[0041] When the lock control unit 405 receives a lock instruction, which will be described later, from at least one of the first smartphone 60 and the second smartphone 70, the lock control unit 405 causes the locking / unlocking device 22 to transition to a locked state.

[0042] 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."

[0043] 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, an input / output I / F, and an internal bus. The second control device 45 (input / output I / F) is connected to the human sensors 28, 31, 35, 39 and the camera 32.

[0044] 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, a camera control unit 451, a person detection unit 452, an entrance / exit information collection unit 453, and a communication control unit 454. Camera control unit 451, person detection unit 452, entrance / exit information collection unit 453, and communication control unit 454 are realized by a CPU reading and executing a program stored in a ROM.

[0045] The camera control unit 451 causes the camera 32 to perform a photographing operation when the motion sensor 35 outputs a detection signal. On the other hand, when the motion sensor 35 stops outputting a detection signal, the camera control unit 451 causes the camera 32 to stop operating.

[0046] The person detection unit 452 determines whether or not image data representing the person to be provided P1A is included in the image data acquired by the camera 32, based on the image data acquired by the camera 32 and the reference image data recorded in the ROM of the second control device 45. For example, the person detection unit 452 uses a pattern matching method to determine whether or not image data representing the person to be provided P1A is included in the image data acquired by the camera 32. In other words, the person detection unit 452 determines whether or not the only person present in the third room 18 is the person to be provided P1A.

[0047] The entrance / exit information collecting unit 453 collects entrance / exit information, which is data acquired by the human sensors 28, 31, 35, 39 and the camera 32 and is information relating to people entering and exiting the building 12.

[0048] The communication control unit 454 transmits the entrance / exit information collected by the entrance / exit information collection unit 453 and the locking / unlocking information received from the first control device 40 to the external server 50 using the wireless communication I / F.

[0049] 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.

[0050] 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 502. The digital key generation unit 501 and the communication control unit 502 are realized by the CPU reading and executing a program stored in the ROM.

[0051] When receiving a request from the first smartphone 60, the digital key generation unit 501 generates a digital key for the first smartphone 60 to operate the locking / unlocking device 22. Furthermore, when receiving a request from the second smartphone 70 carried by the holder P2, the digital key generation unit 501 generates a digital key for the second smartphone 70. The digital key generation unit 501 changes the specifications (contents) of the generated digital key at predetermined intervals. Furthermore, the digital key generation unit 501 sets an expiration date for the digital key generated for the second smartphone 70. In other words, the digital key generation unit 501 generates a digital key for the second smartphone 70 that is valid only during a specific time period on a specific day.

[0052] 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.

[0053] 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 entry / exit information and lock / unlock information wirelessly transmitted from the second control device 45 using the wireless communication I / F and records them in storage.

[0054] 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.

[0055] 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 an entry / exit information request unit. The display control unit, digital key acquisition unit, digital key transmission unit, unlock request unit, lock request unit, and entry / exit 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.

[0056] 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.

[0057] The digital key acquisition unit downloads the digital key transmitted by the external server 50 via the wireless communication I / F.

[0058] The digital key transmitting unit transmits the downloaded digital key to the first control device 40 via the wireless communication I / F.

[0059] When the unlock button included in the operation screen of the owner key operation application is operated (when the relative P1B's hand touches it), the unlock request unit generates an unlock request signal and transmits it to the first control device 40 via the wireless communication I / F.

[0060] 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.

[0061] When the entry / exit information acquisition button included in the operation screen of the owner key operation application is operated, the entry / exit information request unit generates an entry / exit information request signal and transmits it to the external server 50 via the wireless communication I / F.

[0062] 1 is provided with a display 71 having a touch panel. The second smartphone 70 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. A guest key operation application downloaded from the external server 50 is installed on the second smartphone 70.

[0063] 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, and a lock request unit. 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 realized by the CPU reading and executing a program (for example, a guest key operation application) stored in the ROM.

[0064] 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.

[0065] 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.

[0066] In the following description, it is assumed that the relative P1B is outside the building 12 and the recipient P1A is lying on a nursing bed 20.

[0067] Furthermore, a contract is assumed between relative P1B and the day care service provider that states, "When only provided person P1A is present in building 12, holder P2 is permitted to enter building 12 using the digital key. Holder P2 is permitted to enter first room 16, second room 17, and third room 18, but not fourth room 19. Furthermore, the only actions holder P2 is permitted to perform within building 12 are transporting provided person P1A from nursing bed 20 to front door 21, transporting from front door 21 to nursing bed 20 after providing day care services, and other actions incidental thereto." Incidentally, these incidental actions include, for example, opening and closing front door 21, first door 24, and second door 25. Furthermore, when holder P2 arrives at building 12, locking / unlocking device 22 is in the locked state.

[0068] Furthermore, the holder P2 uses a vehicle to travel from the facility of the daycare service provider to a location near the building 12. Furthermore, after the holder P2 gets out of the vehicle, the holder P2 operates the operation button of the operation device 13C, but no sound is output from the speaker.

[0069] 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.

[0070] In step S10 (hereinafter, the word "step" will be omitted), the second smartphone 70 determines whether the current time is within the designated time period. In this case, the second smartphone 70 determines "Yes" in S10 and proceeds to S11.

[0071] In S11, the second smartphone 70 determines whether a BLE link has been established with the first control device 40.

[0072] If the second smartphone 70 determines Yes in S11, the process proceeds to S12, where the digital key transmission unit wirelessly transmits the downloaded digital key to the first control device 40. After completing the process of S12, the second smartphone 70 proceeds to S13.

[0073] 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 S13, it proceeds to 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.

[0074] If the second smartphone 70 determines Yes in S14, the process proceeds to 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.

[0075] When the process of S15 is executed, the locking / unlocking device 22 is unlocked in S28 of Fig. 8, as will be described later, so that the holder P2 can move the front door 21 to the open position and enter the first room 16.

[0076] After completing the process of S15, the second smartphone 70 proceeds to S16 and performs the same process as S11.

[0077] After completing the process of S16, the second smartphone 70 proceeds to S17 and determines whether the lock button included in the operation screen of the guest key operation application has been operated. For example, the holder P2 opens the front door 21 to carry the provided person P1A in the third room 18 to a vehicle, as will be described later, and then closes the front door 21 and operates the lock button.

[0078] If the second smartphone 70 determines "Yes" in S17, the process proceeds to S18, where the lock request unit generates a lock request signal and wirelessly transmits it to the first control device 40.

[0079] When the second smartphone 70 has finished the process of S18 or when it has determined No in S10, 11, 13, 14, 16, and 17, it temporarily ends the process of the flowchart in FIG.

[0080] Next, the flow of processing performed by the first control device 40 will be described with reference to FIG.

[0081] In S20, the first control device 40 performs the same process as in S11.

[0082] After completing the process of S20, the first control device 40 proceeds to S21 and determines whether or not a digital key has been received from the second smartphone 70.

[0083] If the first control device 40 judges "Yes" in S21, the process proceeds to S22, where the digital key acquisition unit 401 issues a request to the external server 50 to transmit the digital key.

[0084] After completing the process of S22, the first control device 40 proceeds to S23 and determines whether or not the digital key has been downloaded from the external server 50.

[0085] If the first control device 40 determines "Yes" in S23, the process proceeds to S24, 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.

[0086] If the first control device 40 determines Yes in S24, it transmits an authentication signal to the second smartphone 70 and proceeds to S25 to determine whether or not it has received an unlock request signal from the second smartphone 70. The first control device 40 then determines whether or not the person present in the building 12 is the person to be provided P1A, based on the information acquired from the second control device. For example, when the person detection unit 452 determines that "the only person present in the third room 18 is the person to be provided P1A," and the human sensors 28, 31, and 39 are not outputting detection signals, the first control device 40 determines that the only person present in the building 12 is the person to be provided P1A.

[0087] If the first control device 40 judges Yes in S25, it proceeds to S26 and sets the value of the locking flag to "0." The initial value of the locking flag is "0." When the specified time period ends, the value of the locking flag becomes "0." Furthermore, when the locking / unlocking device 22 is switched to the locked state using the second smartphone 70, as will be described later, the value of the locking flag becomes "1."

[0088] On the other hand, if the determination in S25 is No, the first control device 40 proceeds to S27. For example, if the first control device 40 determines, based on the information acquired from the second control device, that "multiple people exist in the building 12", that "only one person other than the provideee P1A exists in the building 12", or that "no one exists in the building 12", the first control device 40 determines No in S25.

[0089] For example, when the person detection unit 452 determines that "the only person present in the third room 18 is the provided person P1A" and the human presence sensor 28 outputs a detection signal, the first control device 40 determines that "multiple people are present in the building 12."

[0090] For example, when the person detection unit 452 determines that "image data of one person other than the person to be provided P1A is included" and the human sensors 28, 31, and 39 do not output detection signals, the first control device 40 determines that "only one person other than the person to be provided P1A is present in the building 12."

[0091] For example, when the motion sensors 28, 31, 35, and 39 are not outputting detection signals, the first control device 40 determines that "no one is present in the building 12."

[0092] In S27, the first control device 40 determines whether the value of the lock flag is "1" and whether an unlock request signal has been received from the second smartphone 70. That is, the first control device 40 determines whether an unlock request signal has been received from the second smartphone 70 after the locking / unlocking device 22 was switched to the locked state by the second smartphone 70 during the specified time period. If the first control device 40 determines Yes in S27, it proceeds to S26.

[0093] After completing the processing of S26, the first control device 40 proceeds to S28, 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. For example, if the processing of S28 is performed after a Yes determination is made in S25, the holder P2 can move the front door 21 to the open position and enter the first room 16. Furthermore, the holder P2 can move to the second room 17 by opening the first door 24, and can move to the third room 18 by opening the second door 25. In this way, the holder P2 can move to the third room 18 along the route PS indicated by the dashed line in FIG. 2. That is, the holder P2 can carry the provided person P1A, who is in the third room 18, to a vehicle and use the vehicle to transport the provided person P1A to the facility. Furthermore, if processing of S28 is performed after the judgment of Yes in S27, the holder P2 can return the recipient P1A, who has received day care services at the day care service provider's facility, to the nursing bed 20 by setting the locking / unlocking device 22 to the unlocked state.

[0094] Furthermore, in S28, the communication control unit 406 of the first control device 40 transmits unlocking information based on the unlocking instruction from the second smartphone 70 to the second control device 45.

[0095] When the result of S27 is No or when the process of S28 is completed, the first control device 40 proceeds to S29 and performs the same process as in S20. For example, when the holder P2 approaches the front door 21 while transporting the provided person P1A to the facility of the day care service provider, the first control device 40 determines the result of S29 as Yes.

[0096] If the first control device 40 determines "Yes" in S29, the process proceeds to S30, where it determines whether or not a lock request signal has been received from the second smartphone 70.

[0097] If the first control device 40 determines "Yes" in S30, it proceeds to S31 and sets the value of the lock flag to "1."

[0098] After completing the process of S31, the first control device 40 proceeds to S32, where the lock control unit 405 controls the electric actuator of the locking / unlocking device 22 to transition the locking / unlocking device 22 to a locked state. Furthermore, the communication control unit 406 transmits locking information based on the locking command from the second smartphone 70 to the second control device 45.

[0099] When the first control device 40 has completed the process of S32 or when it has determined No in S20, S21, S23, S24, S29, and S30, it temporarily ends the process of the flowchart of FIG.

[0100] Next, the flow of processing performed by the second control device 45 will be described with reference to FIG.

[0101] In S40, the second control device 45 determines whether unlocking information has been received from the first control device 40.

[0102] If the second control device 45 determines "Yes" in S40, the process proceeds to S41, where the communication control unit 406 wirelessly transmits unlocking information to the external server 50.

[0103] After completing the processing of S41, the second control device 45 proceeds to S42 and determines whether or not a detection signal has been received from any of the human sensors 28, 31, 35, and 39. For example, when the holder P2 is in the second room 17, the second control device 45 receives a detection signal from the human sensor 31 and determines Yes in S42.

[0104] If the second control device 45 determines "Yes" in S42, the process proceeds to S43, where it determines whether or not a detection signal is received from the human presence sensor 35.

[0105] If the second control device 45 determines Yes in S43, it proceeds to S44 and causes the camera 32 to perform the photographing operation while receiving the detection signal from the human sensor 35. That is, for example, when the provided person P1A is lying on the nursing care bed 20, the camera 32 performs the photographing operation. Also, for example, when the provided person P1A is lying on the nursing care bed 20 and the holder P2 is in the third room 18, the camera 32 performs the photographing operation.

[0106] After completing the processing of S44, the second control device 45 proceeds to S45 and wirelessly transmits the entrance / exit information to the external server 50. For example, when the provided person P1A and the holder P2 are in the third room 18, the detection signal of the human sensor 35 and the image data captured by the camera 32 are transmitted to the external server 50 as the entrance / exit information.

[0107] After completing the process of S45, the second control device 45 proceeds to S46 and determines whether locking information has been received from the first control device 40 or not.

[0108] If the second control device 45 determines "Yes" in S46, the process proceeds to S47, where the communication control unit 454 wirelessly transmits the lock information to the external server 50.

[0109] When the second control device 45 has finished the process of S47 or when it has determined No in S46, it temporarily ends the process of the flowchart in FIG.

[0110] Next, the flow of processing performed by the external server 50 will be described with reference to FIG.

[0111] In 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.

[0112] If the external server 50 determines "Yes" in S50, the process proceeds to 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.

[0113] After completing the process of S51, the external server 50 proceeds to S52 and determines whether unlocking information has been received from the second control device 45 or not.

[0114] If the external server 50 determines "Yes" in S52, the process proceeds to 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.

[0115] After completing the process of S53, the external server 50 proceeds to S54 and determines whether or not the entrance / exit information has been received from the second control device 45.

[0116] If the external server 50 determines "Yes" in S54, the process proceeds to S55, where it records the entrance / exit information in association with the ID information of the second smartphone 70 in the storage.

[0117] After completing the process of S55, the external server 50 proceeds to S56 and determines whether lock information has been received from the second control device 45 or not.

[0118] If the external server 50 determines "Yes" in S56, the process proceeds to S57, where it records the locking information in association with the ID information of the second smartphone 70 in the storage.

[0119] After completing the process of S57, the external server 50 proceeds to S58 and determines whether or not an entrance / exit information request signal has been received from the entrance / exit information request unit of the first smartphone 60.

[0120] If the external server 50 determines "Yes" in S58, the process proceeds to S59, where it wirelessly transmits to the first smartphone 60 the locking / unlocking information and the entrance / exit information of the second smartphone 70 that are recorded in the storage.

[0121] When the external server 50 has completed the process of S59, or when it determines No in S52 or S58, it temporarily ends the process of the flowchart in FIG.

[0122] Next, the flow of processing performed by the first smartphone 60 will be described with reference to FIG.

[0123] In S60, the first smartphone 60 determines whether the relative P1B has operated the entry / exit request button included in the operation screen of the owner key operation application.

[0124] If the first smartphone 60 determines "Yes" in S60, the process proceeds to S61, where it wirelessly transmits to the external server 50 the entrance / exit information request signal generated by the entrance / exit information request unit.

[0125] After completing the process of S61, the first smartphone 60 proceeds to S62 and determines whether or not the locking / unlocking information and the entrance / exit information have been received from the external server 50.

[0126] If the first smartphone 60 determines Yes in S62, the process proceeds to S63, and the display control unit controls the display 61. As a result, the locking / unlocking information and the entry / exit 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 holder P2 unlocked the locking / unlocking device 22 of the building 12 and the date and time when the holder P2 locked the locking / unlocking device 22. Furthermore, by operating the display 61 (touch panel), as shown in Fig. 13, the entry / exit information regarding the time when the holder P2 was in each of the rooms 16, 17, 18, and 19, which is acquired based on the detection results of the human sensors 28, 31, 35, and 39, is displayed.

[0127] Furthermore, although not shown in the figure, the photographic data captured by the camera 32 included in the entrance / exit information received by the first smartphone 60 is displayed on the display 61 as a video.

[0128] As described above, according to the system 10 of this embodiment, when the first control device 40 wirelessly communicates with the second smartphone 70 that has received the digital key, authenticates the digital key, and the second control device 45 determines that only the registered person, the provided person P1A, is present in the building 12, the first control device 40 unlocks the locking / unlocking device 22. This allows the holder P2 of the second smartphone 70 to enter the building 12 where only the provided person P1A is present. On the other hand, for example, if the family member is not present in the building 12, the holder P2 cannot enter the building 12 using the digital key. This means that there is little risk that the holder P2, who is not a family member, will behave in the building 12 in a way that makes the family member feel uneasy.

[0129] For example, if the recipient P1A and relative P1B are present in the building 12 and the holder P2 operates the operation button of the operation device 13C, the relative P1B who is also in the building 12 can manually switch the locking / unlocking device 22 to the unlocked state.

[0130] Furthermore, when the motion sensor 32 detects a person in the third room 18, the camera 32 performs a photographing operation. Therefore, there is a possibility that the owner P2 who enters the third room 18 will be photographed by the camera 32. Therefore, there is little risk that the owner P2 will behave in a way that will cause anxiety to the family.

[0131] The building entrance / exit control system according to the embodiment has been described above, but the design of the building entrance / exit control system can be modified as appropriate within the scope of the gist of the present invention.

[0132] For example, the first smartphone 60 may be capable of wirelessly transmitting an emergency signal to a predetermined receiving device (not shown). This receiving device may be installed, for example, in the building of a security company with which the family has a contract. For example, when the owner P2 recognizes suspicious behavior in the third room 18 by looking at the display 61 of the first smartphone 60, the owner P2 can operate an emergency button (not shown) displayed on the display 61 to wirelessly transmit an emergency signal to the first smartphone 60. When this emergency signal is received by the receiving device, a security guard from the security company can rush to the building 12. Furthermore, the security guard may carry a smartphone with the same functions as the first smartphone 60. In this case, the security guard can use the smartphone to unlock the locking / unlocking device 22, allowing the security guard to quickly enter the building 12.

[0133] Alternatively, a locking / unlocking device 22 may be provided on the door 23, and a contract may be concluded between the relative P1B and the daycare service provider stipulating that the holder P2 will enter and exit the third room 18 through the door 23. Furthermore, locking / unlocking devices may be provided on the second door 25 and the third door 26, and only the relative P1B may possess the keys to unlock these locking / unlocking devices. According to this modification, if the locking / unlocking devices on the second door 25 and the third door 26 are kept locked in the building 12 where the provided person P1A is present but the relative P1B is not, the holder P2 will not be able to enter the first room 16, the second room 17, and the fourth room 19, thereby reducing the risk of the holder P2's actions causing anxiety to the family members.

[0134] The camera 32 may be installed in a room other than the third room 18 of the building 12. For example, the first room 16, the second room 17, the third room 18, and the fourth room 19 may each be provided with a camera 32 that is activated when a human sensor in each room detects a person. In this way, even if the provided person P1A is able to walk within the building 12, the second control device 45 (human detection unit 452) can determine whether the provided person P1A is alone in the building 12. Furthermore, since the behavior of the holder P2 in the first room 16, the second room 17, the third room 18, and the fourth room 19 can be photographed by each camera 32, the risk of the holder P2's behavior causing anxiety to the family members is reduced.

[0135] The camera 32 may perform a photographing operation only during the specified time period.

[0136] A sensor other than the camera 32 may be used to detect the provided person P1A in the building 12. This sensor includes, for example, a fingerprint authentication sensor and an iris authentication sensor. In this case, it is preferable to provide the fingerprint authentication sensor or the iris authentication sensor on the nursing bed 20, for example. This allows the provided person P1A, who recognizes that the speaker of the call bell system has emitted the above-mentioned specific sound, to bring his / her body closer to these sensors. Furthermore, when the second control device 45 (person detection unit 452) receives output data from these sensors and detects the provided person P1A, the human sensors 28, 31, and 39 do not output detection signals, and the first control device 40 authenticates the digital key of the second smartphone 70, the locking / unlocking device 22 is unlocked.

[0137] Instead of the first control device 40 and the second control device 45, the building 12 may be provided with a control device having the functions of the first control device 40 and the second control device 45.

[0138] 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.

[0139] The information terminal that receives the locking / unlocking information and the entry / exit 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 that can communicate with the external server 50 via the Internet can be used as the information terminal.

[0140] The holder P2 may be a person who is not a staff member of the day care service provider. [Explanation of symbols]
