[0019] The control unit 60 controls the operations of the entrance hall unit 10, the server 20, the in-room master unit 30, the management room master unit 50, etc. For example, the control unit 60 controls the call state from the entrance hall unit 10 to the in-room master unit 30. The control unit 60 is connected to the external server 70 and the door control device 80 through the network N.

[0020] The controller 60 may include, for example, at least one microcontroller including one or more processors, and other electronic circuits including active elements such as transistors and passive elements. The controller 60 may be composed of multiple CPU cores. The controller 60 may be, for example, an MPU (Micro-Processing Unit), a GPU (Graphics Processing Unit), and / or a TPU (Tensor Processing Unit). The GPU may be composed of multiple GPU cores. Furthermore, the controller 60 may be composed of hardware resources consisting of integrated circuits such as ASICs (Application Specific Integrated Circuits) and FPGAs (Field-Programmable Gate Arrays). In addition, the controller 60 may be composed of a combination of at least one microcontroller and an integrated circuit.

[0021] The external server 70 is a server installed outside the building. The external server 70 may have the function of collecting and generating visitor W's ID information and destination information. Having collected and generated the ID information and destination information, the external server 70 transmits the ID information and destination information to the control unit 60 via the network N.

[0022] The door control device 80 is a device for controlling the locking and unlocking of a door 90 installed at the entrance of an apartment building to which the intercom system 1 is applied. The door control device 80 unlocks the door 90 based on control from the controller 60. The door 90 is an example of a gate. Unlocking the door 90 is an example of opening the gate.

[0023] Network N may be connected to, for example, a terminal device T owned by a visitor W. Terminal device T may be capable of transmitting information about the intercom system 1 through Network N. The controller 60 is also configured to communicate with terminal device T to send and receive signals.

[0024] Figure 2 is a functional block diagram of the intercom system 1, consisting of the main entrance unit 10, server 20, room master unit 30, and control unit 60. As shown in Figure 2, the main entrance unit 10 includes a display unit 11, a call unit 12, and a camera 13, as well as a main entrance unit CPU (Central Processing Unit) 14 and a communication interface (IF) 15.

[0025] The display unit 11 is configured to display the call operation unit 111 and the information input unit 112. In other words, the display unit 11 also functions as an input unit for receiving various operations from the user (for example, a visitor W).

[0026] The call operation unit 111 is an operation unit that a visitor W operates when calling a resident. The call operation unit 111 consists of, for example, a numeric keypad or call buttons displayed on the display unit 11.

[0027] The information input unit 112 is configured to allow input of room information, etc. The room information may include the room number of the resident that visitor W is visiting.

[0028] The communication unit 12 is used by visitors W to the building to call and communicate with people inside the building. The communication unit 12 includes, for example, a microphone and speaker installed in the main entrance unit 10. The communication unit 12 is configured to open a communication line to a living room, allowing residents inside the living room and visitors W in front of the main entrance unit 10 to communicate via the microphone and speaker of the main entrance unit 10.

[0029] The main entrance unit 10 includes a wireless communication terminal 16. The wireless communication terminal 16 is configured to send and receive information to and from a terminal device T owned by a visitor W.

[0030] Figure 3 illustrates the main unit of the collective entrance intercom 10 and the wireless communication terminal 16 located at entrance E. Entrance E, which is accessible to residents and visitors W, and indoor space I, which is accessible only to residents and authorized visitors W, are separated by a door 90. The collective entrance intercom 10 is located in entrance E near the door 90. The wireless communication terminal 16 is located near the main unit of the collective entrance intercom 10 and the door 90. The wireless communication terminal 16 may also be directly attached to the door 90.

[0031] The wireless communication terminal 16 has a defined detection area A that allows it to communicate with terminal equipment T. It is desirable that the detection area A includes the main entrance unit 10.

[0032] Returning to Figure 2, the main entrance unit CPU 14 performs processing to control each part of the main entrance unit 10. The communication IF 15 forms a bidirectional signal transmission path between the main entrance unit CPU 14 and the intercom line L. As a result, a signal transmission path is formed between the main entrance unit CPU 14 and the control unit 60 via the communication IF 15.

[0033] The room master unit 30 includes a display unit 31, an operation unit 32, and a call unit 33, as well as a master unit CPU 34, a communication IF 35, and a storage unit 36. The master unit CPU 34 performs processing to control each part of the room master unit 30. The communication IF 35 forms a bidirectional signal transmission path between the master unit CPU 34 and the intercom line L. This forms a signal transmission path between the master unit CPU 34 and the control unit 60. The storage unit 36 ​​stores control information and the like for the room master unit 30. The storage unit 36 ​​also stores image data captured by the camera 13 of the main entrance unit 10 and the camera 43 of the entrance sub-unit 40, and transmitted from the main entrance unit 10 and the entrance sub-unit 40.

[0034] The control unit 60 comprises a control unit 61 and a storage unit 62. The control unit 61 can communicate with the main entrance unit 10, server 20, room master unit 30, etc., which are connected to the control unit 60, and controls the transmission of signals between each unit and the connection to the network N. The storage unit 62 stores communication information, control information, etc. In this example, the storage unit 62 stores a recorded call table 62a in which the ID information of visitors W is registered in advance.

[0035] The control unit 61 is configured to control the telephone unit 12 and the wireless communication terminal 16 via the main entrance unit CPU 14. The control unit 61 is configured to receive ID information and destination information transmitted from the terminal device T via the wireless communication terminal 16. The control unit 61 also receives a signal containing room number information entered at the call operation unit 111 of the main entrance unit 10. The control unit 61 then refers to the call table 62a in the storage unit 62 to identify the room master unit 30 of the dwelling unit that is associated with the received ID information and destination information or the room number entered at the call operation unit 111. The control unit 61 then transmits a call signal to the identified room master unit 30.

[0036] The control unit 61 is configured to receive visitor W's ID information from the external server 70. The received ID information is stored in the storage unit 62 and transmitted to the server 20. Alternatively, the control unit 61 may forward the ID information received from the external server 70 to the server 20 without storing it in the storage unit 62.

[0037] The server 20 comprises a generation unit 21 and a storage unit 22. The generation unit 21 can generate a predetermined data table 22a based on ID information received from the external server 70 via the controller 60. The storage unit 22 stores the data table 22a generated by the generation unit 21.

[0038] (Operation of Intercom System 1) Next, the operation of the intercom system 1 when a visitor W visits an apartment building to which the intercom system 1 is installed will be described. Note that the intercom system 1 includes a known method of performing a call operation by operating the information input unit 112 displayed on the display unit 11, but this method will not be described in this disclosure. This disclosure will describe a method in which a call operation is performed via terminal equipment T.

[0039] Figure 4 is a flowchart of the call operation of the intercom system 1. When a visitor W enters the detection area A of the wireless communication terminal 16, terminal device T starts communication with the wireless communication terminal 16 and transmits information including ID information and destination information to the wireless communication terminal 16 (step S11). The intercom system 1 may also be configured such that the wireless communication terminal 16 periodically emits a detection signal into the detection area A, and when terminal device T receives the detection signal, it automatically transmits information including ID information and destination information to the wireless communication terminal 16.

[0040] When the wireless communication terminal 16 receives information including ID information and destination information, the control unit 61 determines whether the received ID information matches the ID information registered in the data table 22a (step S12). If the received ID information does not match the ID information registered in the data table 22a (No in step S12), the intercom system 1 does not need to respond to the terminal device T. Alternatively, if the received ID information does not match the ID information registered in the data table 22a (No in step S12), the control unit 61 may have the wireless communication terminal 16 send a signal to the terminal device T to cause the terminal device T to execute a notification indicating that authentication failed.

[0041] If the received ID information matches the ID information registered in the data table 22a (Yes in step S12), the control unit 61 generates a call screen display signal that causes the terminal device T to display the call screen T1 and a voice guidance signal that causes the terminal device T to perform voice guidance about the call screen T1 (step S13). The control unit 61 causes the wireless communication terminal 16 to transmit the call screen display signal and the voice guidance signal (step S14). Upon receiving the call screen display signal and the voice guidance signal from the wireless communication terminal 16, the terminal device T displays the call screen T1 and performs voice guidance about the call screen T1 (step S15). The voice guidance may include information that the call screen T1 has been displayed and instructions on how to operate the call screen T1.

[0042] Figure 5 shows an example of the call screen T1. The call screen T1 displays a message indicating that authentication has been completed, as well as the first operable unit T11 and the second operable unit T12. The first operable unit T11 indicates that the call operation can be performed by operating it. The second operable unit T12 indicates that the call operation can be canceled by operating it.

[0043] In response to an operation on the call screen T1, the terminal device T transmits a call request signal to the wireless communication terminal 16 (step S16). When the first operated part T11 is operated, the terminal device T transmits a call request signal to the wireless communication terminal 16. At this time, in order to reduce the likelihood of erroneous operation, the call request signal may not be transmitted if the first operated part T11 is operated only once, but the call request signal may be transmitted only after the visitor W agrees to a notification asking whether it is really okay to perform the operation.

[0044] When the wireless communication terminal 16 receives a call request signal, the control unit 61 causes the call unit 12 to perform a call operation to the person corresponding to the destination information, based on the destination information received in step S11 (step S17). In this embodiment, the destination information includes the room number. When the call unit 12 starts the call operation, it opens a call line to the room master unit 30 of the room indicated by the room number included in the destination information. This enables communication between the resident in the room and the visitor W in front of the main entrance unit 10.

[0045] If the resident inside the room responds to the call and confirms that visitor W is passing through door 90, the resident can unlock door 90 by operating the room master unit 30.

[0046] It should be noted that there may be cases where the resident does not respond to the call operation due to their absence or other reasons. In this example, the control unit 61 determines whether a predetermined time has elapsed since the start of the call operation (step S18). If the predetermined time has not elapsed since the start of the call operation (No in step S18), step S18 is repeated until the predetermined time has elapsed since the start of the call operation.

[0047] If a predetermined time has elapsed since the start of the call operation (Yes in step S18), the control unit 61 determines that the resident is unable to respond to the call operation. In this case, the control unit 61 may send an open signal to the door control device 80 (step S19). When the door control device 80 receives the open signal, it unlocks the door 90 (step S20).

[0048] When unlocking the door 90, the control unit 61 may output a guidance signal from the wireless communication terminal 16 that includes information about facilities available to the visitor W after passing through the door 90. Upon receiving the guidance signal, the terminal device T begins to provide information about facilities available to the visitor W after passing through the door 90. Facilities available to the visitor W after passing through the door 90 include, for example, an elevator. Therefore, as guidance about facilities available to the visitor W after passing through the door 90, the terminal device T may provide voice guidance such as, "The gate has opened. The elevator is 5m ahead on your right."

[0049] Furthermore, if a predetermined time has elapsed since the start of the calling operation (Yes in step S18), instead of automatically unlocking the door 90, an opening operation screen display signal may be sent to the wireless communication terminal 16 to display an opening operation screen T2, which includes an opening operation section for the visitor W to perform the opening operation (see Figure 7). Details of the opening operation screen T2 will be described later.

[0050] According to the intercom system 1 of this embodiment, calling operations can be performed to people inside the building without requiring operation of the main entrance unit 10 or other components of the intercom system 1, thereby improving the convenience of the intercom system 1. Before the calling operation is performed, the system determines whether the received ID information matches the ID information of the visitor, based on the ID information of the visitor registered in advance, thus improving the security of the intercom system 1. This makes it possible to achieve both improved security and convenience for the intercom system 1 that performs calling operations by visitors W.

[0051] For visually impaired individuals in particular, operating the display unit 11 of the main entrance intercom 10 is not easy. However, since the terminal device T is a device that visually impaired individuals are accustomed to using on a daily basis, it is easier to use than operating the main entrance intercom 10. Therefore, the convenience of the intercom system 1 for visually impaired individuals is improved.

[0052] According to the intercom system 1 of this embodiment, voice guidance is performed along with the display of the call screen T1, making it easier for visitors W to notice the display on the call screen T1 and improving the convenience of operating the call screen T1.

[0053] According to the intercom system 1 of this embodiment, even if the resident is unable to respond to the call, the visitor W can unlock the door 90 based on pre-registered ID information, thus improving the convenience of the intercom system 1.

[0054] According to the intercom system 1 of this embodiment, the wireless communication terminal 16 outputs guidance signals regarding the equipment, making it easier for the visitor W to understand what equipment is available after the door 90 is opened, thus improving convenience for the visitor W.

[0055] Next, the operation of the modified intercom system 1 will be described. In this embodiment, the case in which a call operation is performed based on ID information was described, but in the modified example, no call operation is performed, and an opening operation in which the door 90 is opened based on ID information will be described.

[0056] Figure 6 is a flowchart showing the opening operation of the intercom system 1 in a modified form. When a visitor W enters the detection area A of the wireless communication terminal 16, the terminal device T transmits information including ID information and destination information to the wireless communication terminal 16 (step S21).

[0057] When the wireless communication terminal 16 receives information including ID information and destination information, the control unit 61 determines whether the received ID information matches the ID information registered in the data table 22a (step S22). If the received ID information does not match the ID information registered in the data table 22a (No in step S22), the intercom system 1 does not need to respond to the terminal device T. Alternatively, if the received ID information does not match the ID information registered in the data table 22a (No in step S22), the control unit 61 may have the wireless communication terminal 16 send a signal to the terminal device T to cause the terminal device T to execute a notification indicating that authentication failed.

[0058] If the received ID information matches the ID information registered in data table 22a (Yes in step S22), the control unit 61 generates an open operation screen display signal that causes terminal device T to display the open operation screen T2 and a voice guidance signal that causes terminal device T to perform voice guidance about the open operation screen T2 (step S23). The control unit 61 causes wireless communication terminal 16 to transmit the open operation screen display signal and the voice guidance signal (step S24). Upon receiving the open operation screen display signal and the voice guidance signal from wireless communication terminal 16, terminal device T displays the open operation screen T2 and performs voice guidance about the open operation screen T2 (step S25). The voice guidance may include information that the open operation screen T2 has been displayed and instructions on how to operate the open operation screen T2.

[0059] Figure 7 shows an example of the opening operation screen T2. ​​The opening operation screen T2 displays a message indicating that authentication has been completed, as well as the third operable part T21 and the fourth operable part T22. The third operable part T21 indicates that the door 90 can be opened by operating it. The third operable part T21 is an example of an opening operation part. The fourth operable part T22 indicates that the opening operation can be canceled by operating it.

[0060] In response to an operation on the release operation screen T2, the release operation screen T2 transmits an release signal to the wireless communication terminal 16 (step S26). When the third operated unit T21 is operated, the terminal device T transmits an release signal to the wireless communication terminal 16.

[0061] When the wireless communication terminal 16 receives an open signal, the control unit 61 sends an open request signal to the door control device 80 (step S27). When the door control device 80 receives the open request signal, it unlocks the door 90 (step S28).

[0062] According to the modified intercom system 1, the door 90 can be opened without requiring operation of the main entrance unit 10 or other components of the intercom system 1, thus improving the convenience of the intercom system 1. Before the opening operation is performed, the system determines whether the received ID information matches the ID information of the visitor, based on the ID information of the visitor registered in advance, thus improving the security of the intercom system 1. This makes it possible to achieve both security and convenience, especially for visually impaired people, for the intercom system 1 that allows visitors W to open the door.
