[0012] Before describing the present disclosure in detail, an overview will be provided. The embodiment relates to an intercom system installed in a collective facility such as an apartment or condominium. A collective facility includes a plurality of facilities such as residences, and people can enter and exit through at least one common entrance. When a visitor operates a common entrance device such as a lobby intercom installed at the common entrance, a home information panel installed at the facility being visited is called. In response to the call, a resident of the facility operates the home information panel to confirm the visitor and then responds, and the visitor and resident can talk to each other via the common entrance device and the home information panel. The resident can also unlock the electric lock of the common entrance by operating the home information panel.

[0013] Such communication within the collective facility is performed via a trunk line provided in the collective facility. Some residents of the collective facility wish to respond to a visitor's visit and unlock the electric lock even when they are out. For this reason, it is required to easily execute communication between the trunk line in the collective facility and a terminal device such as a smartphone carried by a resident. The intercom system according to this embodiment transmits a short message to the terminal device via a network connected to the trunk line when there is no response to a call to the facility. At that time, the short message indicates an image of the visitor captured at the common entrance and the address of a server (hereinafter referred to as a "lock control server") that can control the electric lock from the outside. When the resident receives the message on the terminal device, he / she confirms the visitor from the image and then accesses the lock control server to unlock the electric lock.

[0014] 1 shows the configuration of an intercom system 1000. The collective facility 100 includes a first facility 110a, a second facility 110b, and a third facility 110c, which are collectively referred to as facilities 110. The number of facilities 110 in the collective facility 100 is not limited to "3". The intercom system 1000 includes a common entrance device 200, a control device 300, a collective facility GW (GateWay) 310, a network 320, an SMS (Short Message Service) server 330, a common area trunk line 350, an occupied trunk line 360, a management room terminal 370, a home information panel 400, a front door sub unit 480, an electric lock 500, an external line adapter 510, a public line network 520, a lock control server 550, and a terminal device 600. The home information panel 400 and the front door sub unit 480 are shown only in the first facility 110a, but are also included in the second facility 110b and the third facility 110c. Here, (1) basic operation of the intercom system 1000, (2) communication with the terminal device 600 in the intercom system 1000, (3) unlocking operation of the electric lock 500 from the terminal device 600, and (4) modified examples will be described in this order. In this case, Figures 2(a)-(b) will also be used.

[0015] (1) Basic operation of the intercom system 1000 In the collective facility 100, a plurality of facilities 110 are gathered together. An example of the collective facility 100 is an apartment building, and an example of the facilities 110 is a residence. A common entrance device 200 is installed at the common entrance of the collective facility 100. The common entrance device 200 is, for example, a lobby intercom installed in the lobby of the apartment building. Figures 2(a)-(b) show the configuration of the common entrance device 200 and the home information panel 400. Figure 2(a) shows the configuration of the common entrance device 200. The common entrance device 200 includes a processing unit 210, an operation unit 230, a control unit 240, and a communication unit 250, and the processing unit 210 includes an imaging unit 212, a microphone 214, a speaker 218, a monitor 220, and an IF unit 222.

[0016] The operation unit 230 of the common entrance apparatus 200 is a user interface for accepting operations by a visitor, such as a call button. When the operation unit 230 accepts the number of the facility 110 to be visited from the visitor, it outputs a call request to the control unit 240. When the operation unit 230 is operated by the visitor, the processing unit 210 operates.

[0017] The imaging unit 212 is for photographing visitors, and includes a solid-state imaging element such as a CMOS (Complementary Metal Oxide Semiconductor) image sensor or a CCD (Charge Coupled Device) image sensor. The solid-state imaging element outputs a photoelectrically converted video signal to the IF unit 222. The IF unit 222 performs various signal processing on the video signal from the imaging unit 212. Since known techniques may be used for the various signal processing, a description thereof will be omitted here. The IF unit 222 outputs the video signal that has undergone signal processing (hereinafter also referred to as the "video signal") to the control unit 240.

[0018] The microphone 214 and the speaker 218 are user interfaces that allow the visitor to talk to the resident. The microphone 214 collects the visitor's voice, converts it into an electrical signal, and outputs it to the IF unit 222. The speaker 218 reproduces the electrical signal from the IF unit 222 and outputs the audio. The IF unit 222 receives the electrical signal from the microphone 214 and converts it into a signal in a format for transmission (hereinafter referred to as an "audio signal"). The IF unit 222 outputs the audio signal to the control unit 240. Meanwhile, the IF unit 222 inputs the audio signal from the control unit 240 and converts the audio signal into an electrical signal. The IF unit 222 outputs the electrical signal to the speaker 218.

[0019] The monitor 220 displays messages and the like. The IF unit 222 inputs a message signal from the control unit 240 and outputs the message signal to the monitor 220. The message signal may be generated in the common entrance device 200. The control unit 240 controls the operation of the common entrance device 200. The control unit 240 is connected to the communication unit 250. The communication unit 250 is connected to the control device 300 via the common area trunk line 350, and executes communication with the home information panel 400 via the control device 300. To be more specific, the communication unit 250 transmits and receives the above-mentioned call request, video signal, audio signal, and message signal to and from the home information panel 400, but the signals transmitted and received are not limited to these. Return to FIG. 1.

[0020] The control device 300 is installed in a common space such as a machine room or a manager's room, and relays signals between the common entrance device 200 and the home information panel 400. The common area trunk line 350 and the occupied trunk line 360 ​​are transmission lines for transmitting call signals from the common entrance device 200 and response signals from the home information panel 400. The common area trunk line 350 and the occupied trunk line 360 ​​transmit the above-mentioned call requests, video signals, audio signals, and message signals.

[0021] The home information panel 400 is installed in the facility 110, and is also called a dwelling unit unit, a dwelling unit terminal, a facility master unit, a room master unit, or a home master unit. Fig. 2(b) shows the configuration of the home information panel 400. The home information panel 400 includes a processing unit 410, an operation unit 430, a control unit 440, and a communication unit 450, and the processing unit 410 includes a microphone 414, a speaker 418, a monitor 420, and an IF unit 422.

[0022] The communication unit 450 is connected to the control device 300 via the occupied trunk line 360, and executes communication with the common entrance apparatus 200 via the control device 300. The communication unit 450 is connected to the control unit 440, which controls the operation of the house information panel 400. The control unit 440 is connected to the IF unit 422 and the operation unit 430, and the IF unit 422 is connected to the microphone 414, the speaker 418, and the monitor 420. Here, the microphone 414, the speaker 418, the IF unit 422, and the operation unit 430 are configured in the same manner as the microphone 214, the speaker 218, the IF unit 222, and the operation unit 230. The monitor 420 displays an image captured by the imaging unit 212 of the common entrance apparatus 200.

[0023] The control unit 440 receives a call request, a video signal, and an audio signal from the common entrance apparatus 200 via the communication unit 450. When the control unit 440 receives the call request, it outputs a ring tone from the speaker 418 via the IF unit 422. Subsequently, the control unit 440 displays an image reproduced from the video signal on the monitor 420 via the IF unit 422, and outputs an audio reproduced from the audio signal from the speaker 418 via the IF unit 422. When a resident who hears the ring tone responds to the call by operating the operation unit 430, the control unit 440 causes the communication unit 450 to execute communication with the common entrance apparatus 200. As a result, a video signal and an audio signal are communicated between the communication unit 250 and the communication unit 450, and a call is executed between the visitor who operates the common entrance apparatus 200 and the resident who operates the house information panel 400.

[0024] An electric lock 500 is installed at the common entrance of the intercom system 1000, and the electric lock 500 locks the common entrance. The electric lock 500 is connected to the home information panel 400 via the control device 300. When a resident operates the operation unit 430 of the home information panel 400, the communication unit 450 transmits an unlock instruction to the control device 300 to instruct the control device 300 to unlock the electric lock 500 based on the unlock instruction. After unlocking, when a certain period of time has passed, the electric lock 500 is automatically locked. Return to FIG. 1.

[0025] A front door sub-unit 480 installed outside the front door of the facility 110 is connected to the home information panel 400. The front door sub-unit 480 is also called a door intercom, a room sub-unit, or a facility sub-unit. The front door sub-unit 480 may be configured similarly to the common front door device 200, and therefore a description thereof will be omitted here. Therefore, a call is made between a visitor operating the front door sub-unit 480 and a resident operating the home information panel 400. If an electric lock (not shown) is installed at the front door of the facility 110, the resident can unlock the electric lock by operating the home information panel 400.

[0026] The management room terminal 370 is connected to the control device 300 and is installed in a manager's room. The management room terminal 370 is also called a shared parent device. The management room terminal 370 is used by the manager of the apartment complex to, for example, check the settings of the control device 300 or to set up the control device 300.

[0027] (2) Communication with the terminal device 600 in the intercom system 1000 The collective facility GW310 is a communication device for connecting the control device 300 inside the collective facility 100 to a network 320 outside the collective facility 100. Therefore, it can be said that the collective facility GW310 relays communication inside and outside the collective facility 100. Since an SMS server 330 is connected to the network 320, the home information panel 400 can communicate with the SMS server 330 via the control device 300, the collective facility GW310, and the network 320. In addition, since a terminal device 600 is connected to the network 320, the terminal device 600 can communicate with the SMS server 330 via the network 320.

[0028] Since the lock control server 550 is also connected to the network 320, the terminal device 600 can communicate with the lock control server 550 via the network 320, and the control device 300 can communicate with the lock control server 550 via the collective facility GW 310 and the network 320. The terminal device 600 is a communication device carried by a resident of the facility 110 or a manager of the collective facility 100, and is, for example, a smartphone or a PC.

[0029] The external line adapter 510 is a communication device for connecting the control device 300 inside the collective facility 100 to a public line network 520 outside the collective facility 100. The external line adapter 510 can communicate with the terminal device 600 via the public line network 520. For example, voice communication is performed in the public line network 520. The terminal device 600 can perform telephone calls by being connected to the public line network 520.

[0030] (3) Unlocking the electric lock 500 from the terminal device 600 Here, the operation for the terminal device 600 to respond to a call from the common entrance device 200 will be described. The operation unit 430 of the home information panel 400 in FIG. 2(b) receives an operation for setting to the outside mode from a resident who is going out from the facility 110. When the operation unit 430 receives the setting of the outside mode, the control unit 440 sets the outside mode. The memory unit 460 stores information related to the terminal device 600 to be used in the outside mode. The information related to the terminal device 600 includes the telephone number of the terminal device 600. Such a terminal device 600 can be said to be a mobile phone terminal associated with the home information panel 400.

[0031] In such a situation, when a visitor operates the common entrance apparatus 200, a call request, a video signal, and an audio signal are transmitted from the common entrance apparatus 200 to the house information panel 400. When the common entrance apparatus 200 is called a call source apparatus, the house information panel 400 is called a called apparatus. The acquisition unit 442 receives the call request, the video signal, and the audio signal from the common entrance apparatus 200 as information based on the call.

[0032] When the acquisition unit 442 receives information based on the call, the control unit 440 extracts the telephone number of the terminal device 600 from the storage unit 460. The control unit 440 generates information (hereinafter referred to as "first information") for outputting a notification to the terminal device 600 using the telephone number of the terminal device 600. At this time, the notification includes information indicating an access destination for enabling the terminal device 600 to unlock the electric lock 500, for example, information on the address of the lock control server 550. At least one of an expiration date and an effective number of times is set for unlocking by the lock control server 550. The notification also includes an image extracted from the video signal. The first output unit 444 outputs the first information to the collective facility GW 310 via the control device 300.

[0033] Furthermore, when the control unit 440 extracts the telephone number of the terminal device 600 from the storage unit 460, it generates information (hereinafter referred to as "second information") for making an outside call to the terminal device 600. The second information includes the telephone number of the terminal device 600. The second output unit 446 outputs the second information to the outside line adapter 510 via the control device 300.

[0034] The collective facility GW310 receives the first information from the house information panel 400 via the control device 300, and transmits the first information to the SMS server 330 via the network 320. The SMS server 330 generates a notification based on the first information. As described above, the notification includes information on the address of the lock control server 550 and an image extracted from the video signal. The SMS server 330 transmits the notification as a short message. The destination of the notification is indicated by the telephone number of the terminal device 600. The outside line adapter 510 receives the second information from the house information panel 400 via the control device 300. The outside line adapter 510 executes an outside call with the telephone number of the terminal device 600 as the destination.

[0035] The terminal device 600 receives a notification from the SMS server 330 via the network 320. The terminal device 600 displays the received notification on a screen. FIG. 3 shows a screen displayed on the terminal device 600. On the screen, a message 610 saying "There was a call", an attached image 612 showing an image of the visitor captured by the imaging unit 212 of the common entrance device 200, and a remote unlocking link 614 showing the address of the lock control server 550 are displayed. The terminal device 600 also receives an external call from the external line adapter 510 via the public line network 520. When the resident answers the external call, the terminal device 600 executes communication with the common entrance device 200 via the public line network 520, the external line adapter 510, the control device 300, the house information panel 400, and the control device 300. As a result, a call is made between the resident and the visitor.

[0036] Through these processes, the resident confirms the visitor by talking to the visitor while looking at the attached image 612 of the visitor displayed on the screen of the terminal device 600. When the resident decides to unlock the electric lock 500, the resident selects the remote unlock link 614. When the terminal device 600 accepts the selection, it transmits a signal indicating an instruction to unlock the electric lock 500 (hereinafter referred to as an "unlock signal") to the lock control server 550 via the network 320. The lock control server 550 prestores a correspondence relationship between the source of the unlock signal and the address of the collective facility GW310 of the collective facility 100, and identifies the address of the collective facility GW310 based on the source of the received unlock signal. The lock control server 550 transmits the unlock signal to the identified address of the collective facility GW310. At least one of an expiration date and a valid number of times is set for the unlocking at the lock control server 550 by the unlock signal. In addition, the remote unlock link 614 may be invalidated when the call ends.

[0037] When the collective facility GW310 receives an unlocking signal from the SMS server 330 via the network 320, it transmits the unlocking signal to the control device 300. The control device 300 unlocks the electric lock 500 based on the unlocking instruction. As a result, even if a resident is located away from the collective facility 100, the electric lock 500 can be remotely unlocked by operating the terminal device 600.

[0038] (4) Variations In the above description, when the home information panel 400 receives information based on the call, it transmits the first information to the collective facility GW310. At that time, the home information panel 400 manages information such as the telephone number of the terminal device 600 and the address of the lock control server 550, and uses the information when generating the first information. These pieces of information may be managed in the collective facility GW310. When the home information panel 400 is set to the away mode, it transmits the information based on the call to the collective facility GW310 via the control device 300. Such a home information panel 400 may be called an information notification system.

[0039] 4 shows the configuration of the collective facility GW310. The collective facility GW310 includes a first communication unit 700, a second communication unit 702, a control unit 710, and a storage unit 720, and the control unit 710 includes an acquisition unit 712 and an output unit 714. The first communication unit 700 executes a communication method similar to that of the common area trunk line 350 and the occupied trunk line 360, and can communicate with the control device 300. Therefore, the first communication unit 700 also communicates with each home information panel 400 via the control device 300. The second communication unit 702 can communicate with the network 320, and communicates with the SMS server 330 and the lock control server 550 via the network 320.

[0040] The first communication unit 700 receives information based on the call from the home information panel 400 via the control device 300. The acquisition unit 712 of the control unit 710 acquires the information based on the call. When the acquisition unit 712 of the control unit 710 receives the information based on the call, the control unit 710 extracts the telephone number of the terminal device 600 from the storage unit 720. The control unit 710 generates information (hereinafter referred to as "first information") for outputting a notification using the telephone number of the terminal device 600 to the terminal device 600. At that time, the notification includes information indicating an access destination for enabling the terminal device 600 to unlock the electric lock 500, for example, information on the address of the lock control server 550. The notification also includes an image extracted from the video signal. At least one of an expiration date and an effective number of times is set for unlocking at the lock control server 550. The notification also includes an image extracted from the video signal. The second communication unit 702 transmits the first information to the SMS server 330 via the network 320. The subsequent processing is the same as before, so a description thereof will be omitted here.
