[0012] The details of the embodiments will be described below with reference to the drawings. However, the embodiments described below are merely examples, and the autolock system according to the present disclosure is not limited to the configurations described below. Furthermore, specific configurations according to the embodiments may be appropriately adopted in implementation, and various improvements and modifications may be made.

[0013] A system 1 according to one embodiment will be described. This system is an example of a building visitor response system. The following description assumes that a visitor to a building interacts with a resident living in the building, enters the building, goes to the resident's room, and interacts with the resident before visiting. While the following description of the system 1 assumes that there are multiple buildings, it goes without saying that the system may be configured to have only one building.

[0014] As shown in Figure 1, there is a building system 10 that manages the entrance and exit of a building, and the system 1 is composed of multiple building systems 10 and a server 20 that simultaneously manages and processes them, and the building systems 10 and the server 20 exchange various information with each other via a network. The server 20 manages various information about the buildings, their residents, etc. for multiple buildings.

[0015] Next, as shown in Figure 2, the building system 10 comprises an information processing device 30 that manages entry and exit to the building, an information processing terminal 40 that is easily carried and can be used for various communications and exchange of various information with the server 20, a common area autolock 50 that manages the opening and closing of the entrance door that separates the inside and outside of the building, an intercom terminal 60 that is installed near the outside of each of the multiple room doors in the building and can communicate with the occupants of each room, and a door lock 70 that controls the locking and unlocking of the doors that separate the inside and outside of each room.

[0016] To briefly explain each of these, the server 20 stores various information such as the building number, the room number of the building, and the telephone number of the information processing terminal 40 that can contact the resident (it does not have to be a telephone number, but can be a LINE ID or the like).In addition, various applications, such as an application that can contact the resident, are installed.

[0017] Server 20 also transmits and receives information such as data via a network to information processing device 30, information processing terminal 40, common area autolock 50, intercom terminal 60, and door lock 70. Details of the exchange of information between server 20 and information processing device 30, information processing terminal 40, common area autolock 50, intercom terminal 60, and door lock 70 will be described later.

[0018] Information processing device 30 accepts input of the room number of a resident that a visitor to the building wishes to contact, and also exchanges various information with server 20.

[0019] The information processing terminal 40 is owned by a resident of the building and is capable of contacting the outside world and exchanging various information with the server 20. An example of the information processing terminal referred to here is a smartphone.

[0020] The common area autolock 50 is a locked door that separates the inside and outside of the building, and exchanges various information with the server 20, and performs various operations such as unlocking and locking the entrance door according to instructions and opening and closing the entrance door.

[0021] The intercom terminal 60 allows visitors to a room in the building to converse with the resident of that room, and also exchanges various information with the server 20.

[0022] The door lock 70 not only locks and unlocks the door that separates the inside and outside of the room to open and close the door, but also exchanges various information with the server 20.

[0023] The following is a rough explanation of the process. A visitor to a building (not shown) comes to the entrance door in front of autolock 50, which separates the inside and outside of the entire building in the common area at the entrance to the building, and operates the installed information processing device 30 to specify the room number of the building resident they wish to visit and call the building resident. The called building resident's information processing terminal 40 is notified that a visitor has arrived. The building resident operates their own information processing terminal 40, and after a line is established between information processing device 30 and information processing terminal 40, they begin communicating with the visitor. The building resident communicates with the visitor by phone or other means, and decides that it is okay to invite the visitor into the building. They then operate their own information processing terminal 40 to send an instruction to unlock common area autolock 50. Upon receiving the unlock instruction, common area autolock 50 unlocks the door and opens the entrance door, allowing the visitor to enter the building.

[0024] The visitor then enters the building, comes to the door of the room they wish to visit, and operates the intercom terminal 60 installed next to the door to call the resident of that room. The information processing terminal 40 of the called resident is notified that there is a visitor at the door of the room. The resident operates their own information processing terminal 40, and after a line is established between the information processing terminal 40 and the intercom terminal 60, they begin communicating with the visitor. The resident communicates with the visitor by phone or other means, and when they decide that it is okay to invite the visitor into the room, they operate their own information processing terminal 40 to send an instruction to unlock the door lock 70. Upon receiving the unlock instruction, the door lock 70 unlocks the door and opens, allowing the visitor to enter the room.

[0031] 5, a process executed to unlock the common area autolock 50 of the system 1 and allow a visitor into the building will be described. In this embodiment, the server 20, the information processing device 30, the information processing terminal 40, and the common area autolock 50 are all in operation.

[0032] 5 is a flowchart of the processing executed by server 20, information processing device 30, information processing terminal 40, and common area autolock 50. Note that control unit 210 of server 20, control unit 310 of information processing device 30, control unit 410 of information processing terminal 40, and control unit 510 of common area autolock 50 execute the processing of the flowchart shown in FIG.

[0033] In step S11, a visitor to the building comes to common area autolock 50, which is located in the common area at the entrance to the building and separates the inside from the outside of the entire building, and operates information processing device 30 installed in front of common area autolock 50, and specifically inputs the room number they wish to visit from input unit 340. Control unit 310 transmits the information on the room number and building number input from input unit 340 to server 20 from communication unit 330.

[0034] Next, in step S12, server 20 receives the room number and building number transmitted by control unit 310 of information processing device 30 via communication unit 330 at communication unit 230, and based on the information on the resident's information processing terminal corresponding to the building number and room number stored in memory unit 220, transmits an instruction to display that a visitor has arrived and / or an instruction to ring information processing terminal 40 via communication unit 230 to communication unit 430 of information processing terminal 40 to notify the resident's information processing terminal 40 that a visitor has arrived.

[0035] Next, in step S13, information processing terminal 40 receives, via communication unit 430, the instruction sent by control unit 210 of server 20 via communication unit 230, and displays on display unit 450 and / or rings information processing terminal 40 that a visitor has come to common area autolock 50, which is located in the common area at the entrance to the building and separates the inside and outside of the entire building, and is operating information processing device 30 installed in front of common area autolock 50. Then, the resident of the room number (not shown) operates information processing terminal 40, specifically pressing a button displayed on display unit 450 to notify that there is a visitor, or pressing a button to start communication with information processing device 30. Information processing terminal 40 establishes communication with information processing device 30, and the resident begins communication with the visitor.

[0043] Next, in step S22, the server 20 receives the information sent by the control unit 610 of the intercom terminal 60 via the communication unit 630 at the communication unit 230, and based on the information of the resident's information processing terminal corresponding to the building number and room number stored in the memory unit 220, sends an instruction to display that the intercom terminal 60 in front of the room has been operated and / or an instruction to ring the information processing terminal 40 via the communication unit 230 to the communication unit 430 of the information processing terminal 40, in order to notify the resident's information processing terminal 40 that a visitor has come to the door of the room and is operating the intercom terminal 60 in front of the room.

[0044] Next, in step S23, information processing terminal 40 receives, via communication unit 430, the instruction sent by control unit 210 of server 20 via communication unit 230, and displays on display unit 450 that a visitor has arrived at the door of the room and is operating intercom terminal 60 in front of the room and / or rings information processing terminal 40. The resident then operates information processing terminal 40, specifically, pressing a button displayed on display unit 450 to indicate that the visitor is operating intercom terminal 60 in front of the room, or pressing a button to start communication with intercom terminal 60. Information processing terminal 40 establishes communication with intercom terminal 60, and the resident begins communication with the visitor. The resident determines whether to invite the visitor into the room through communication such as a phone call with the visitor, and if the resident decides to invite the visitor into the room, operates information processing terminal 40, specifically, performing an unlocking operation such as pressing a button displayed on information processing terminal 40 to unlock the door. When the unlocking operation is performed, the control unit 410 transmits an instruction to unlock the door lock 70 of the room from the communication unit 430 to the server 20.

[0045] Next, in step S24, the server 20 receives, via the communication unit 230, the instruction to unlock the door lock 70 of the living room that has been transmitted by the control unit 410 of the information processing terminal 40 via the communication unit 430, and starts the unlocking operation. Specifically, based on the received instruction to unlock the door lock 70 of the living room, the control unit 210 transmits an instruction to unlock the door lock 70 from the communication unit 230 to the door lock 70.

[0046] Next, in step S25, the door lock 70 receives the unlock instruction sent by the control unit 210 of the server 20 via the communication unit 230 via the communication unit 730, and performs an operation to unlock the door in front of the room.

[0047] This allows the visitor to enter the room. [Explanation of symbols]
