[Diagram 5] FIG. 11 is a diagram showing a configuration of an intercom system according to a second embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Example 1 Before specifically describing the present disclosure, an overview will be provided. Example 1 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. A visitor operates a common entrance device such as a lobby intercom installed at the common entrance to call a home information panel installed at the facility he or she is visiting. For example, a call request from the common entrance device is transmitted to the home information panel. In addition, together with the call request, audio signals and video signals acquired by the common entrance device are also transmitted to the home information panel. In response to the call, a resident of the facility confirms the visitor by operating the home information panel. When the resident operates the home information panel to respond to the call, a visitor call is executed between the common entrance device and the home information panel.

[0012] Generally, the common entrance device and the home information panel are connected via a control device for controlling visitor calls, and a cable such as a trunk line is used for the connection. Therefore, the labor required for constructing the connection using the cable increases. In order to suppress such an increase in labor, it is effective to connect the common entrance device, the home information panel, etc., via a wireless communication system, for example, a wireless LAN (Local Area Network). When a wireless communication system is used, the strength of the wireless signal is attenuated by multiple obstacles such as walls placed between the common entrance device and the home information panel in the facility. The attenuation of the wireless signal strength may cause a decrease in the quality of visitor calls or may make it impossible to make visitor calls between the common entrance device and the home information panel.

[0013] In the intercom system according to the present embodiment, a common entrance device is connected to an entrance device installed at the entrance of each facility and connected to a home information panel in the facility by wires via a wireless communication system. The entrance device is generally installed on the side of the corridor facing the facility. Therefore, the number of obstacles between the common entrance device and the entrance device is less than the number of obstacles between the common entrance device and the home information panel. As a result, attenuation of the strength of the wireless signal is suppressed when the common entrance device and the entrance device are connected by a wireless communication system, compared to when the common entrance device and the home information panel are connected by a wireless communication system. Visitor calls between the common entrance device and the home information panel are made via the entrance device.

[0014] In such a configuration, the entrance device needs to be set to execute wireless communication with the common entrance device. However, in general, the entrance device is only provided with a call button for calling the house information panel, and does not have an interface that can be operated for setting up wireless communication. In this embodiment, the setting contents in the entrance device are displayed on the screen of the terminal device as two-dimensional information. In addition, in the entrance device, the call button is pressed down longer than usual to start a two-dimensional information reading mode, and then the two-dimensional information displayed on the screen of the terminal device is read by the imaging unit. The entrance device executes the setting of wireless communication based on the read two-dimensional information.

[0015] FIG. 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 the facility 110. The intercom system 1000 includes a common entrance device 200, an electric lock 300, a first housing information board 400a, a second housing information board 400b, and a third housing information board 400c, which are collectively referred to as the housing information board 400, and a first entrance device 500a, a second entrance device 500b, and a third entrance device 500c, which are collectively referred to as the entrance device 500. The number of facilities 110 in the collective facility 100 is not limited to "3", and the number of housing information boards 400 and entrance devices 500 is also not limited to "3". Below, the intercom system 1000 shown in FIG. 1(a) will be described in the order of (1) collective facility intra-communication, (2) intra-facility communication, and (3) wireless communication settings.

[0016] (1) Communications within collective facilities In an collective facility 100, multiple facilities 110 are gathered together. An example of the collective facility 100 is an apartment building, and an example of the facility 110 is a residence. A shared common entrance device 200 is installed at the common entrance of the collective facility 100, that is, outside the multiple facilities 110. The common entrance device 200 is, for example, a lobby intercom installed in the lobby of the apartment building. In addition, an electric lock 300 installed at the common entrance is normally locked, so visitors cannot enter the facility 110 unless the electric lock 300 is unlocked.

[0017] 2(a)-(c) show the configurations of the common entrance device 200, the entrance device 500, and the house information panel 400. Fig. 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 216, a monitor 218, and an IF unit 220.

[0018] 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. The call request includes the number of the facility 110 accepted by the operation unit 230. When the operation unit 230 is operated by the visitor, the processing unit 210 operates.

[0019] The imaging unit 212 includes a solid-state imaging element such as a complementary metal oxide semiconductor (CMOS) image sensor or a charge coupled device (CCD) image sensor, and captures an image of a visitor. The solid-state imaging element outputs a photoelectrically converted video signal to the IF unit 220. The IF unit 220 performs various signal processing on the video signal from the imaging unit 212. Known techniques may be used for the various signal processing, and therefore a description thereof will be omitted here. The IF unit 220 outputs the video signal that has undergone signal processing (hereinafter also referred to as the "video signal") to the control unit 240.

[0020] The microphone 214 and the speaker 216 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 220. The IF unit 220 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 220 outputs the audio signal to the control unit 240. Meanwhile, the IF unit 220 inputs the audio signal from the control unit 240 and converts the audio signal into an electrical signal. The IF unit 220 outputs the electrical signal to the speaker 216. The speaker 216 reproduces the electrical signal from the IF unit 220 and outputs the audio.

[0021] The monitor 218 displays messages, etc. The IF unit 220 inputs a message signal from the control unit 240 and outputs the message signal to the monitor 218. The message signal may be generated in the common entrance apparatus 200.

[0022] The control unit 240 controls the operation of the common entrance device 200. The control unit 240 also has the function of a control device in the intercom system 1000. Fig. 3 shows the data structure of a table held in the control unit 240. As shown in the figure, communication information, which is information required to execute communication with the entrance device 500, is stored so as to correspond to a room number, that is, the number of the facility 110. The communication information includes, for example, the device ID, MAC address, and IP address of the entrance device 500. Other information may also be stored. Return to Fig. 2(a).

[0023] When the control unit 240 receives a call request from the operation unit 230, it extracts the number of the facility 110 included in the call request. The control unit 240 acquires communication information of the entrance device 500 corresponding to the number of the facility 110 based on the table it holds. The control unit 240 controls wireless communication with the entrance device 500 that is the target of wireless communication with the common entrance device 200 based on the acquired communication information. Since the entrance device 500 is connected to the home information panel 400, it can be said that the control unit 240 controls wireless communication with the home information panel 400 connected to at least one of the multiple entrance devices 500.

[0024] The communication unit 250 executes wireless communication corresponding to the wireless communication system. When the wireless communication system is, for example, a wireless LAN, the communication unit 250 can execute wireless communication with a plurality of entrance devices 500 by executing processing of an access point of the wireless LAN. The communication unit 250 may also execute wireless communication with a plurality of entrance devices 500 by ad-hoc communication. For wireless communication, an SSID (Service Set Identifier) ​​is set in the communication unit 250. The communication unit 250 transmits a call request, a video signal, and an audio signal to the entrance device 500, with the communication information acquired by the control unit 240 as the destination. After completing the connection with the entrance device 500, the communication unit 250 transmits a video signal to the house information panel 400 via the entrance device 500, and transmits and receives an audio signal. Furthermore, the communication unit 250 may transmit and receive a message signal between the house information panel 400 and the communication unit 250. Return to FIG. 1.

[0025] The entrance device 500 is an intercom installed outside the entrance of the facility 110. Fig. 2(b) shows the configuration of the entrance device 500. The entrance device 500 includes a processing unit 510, an operation unit 530, a control unit 540, and a first communication unit 550a and a second communication unit 550b collectively referred to as a communication unit 550, and the processing unit 510 includes an imaging unit 512, a microphone 514, a speaker 516, and an IF unit 520. The imaging unit 512, the microphone 514, the speaker 516, and the IF unit 520 are configured in the same manner as the imaging unit 212, the microphone 214, the speaker 216, and the IF unit 220 in Fig. 2(a).

[0026] The first communication unit 550a executes wireless communication compatible with a wireless communication system, for example, wireless LAN. Therefore, the first communication unit 550a communicates wirelessly with the common entrance apparatus 200. The control unit 540 is connected to the first communication unit 550a, and the control unit 540 controls the operation of the entrance apparatus 500. The second communication unit 550b is connected to the control unit 540. The second communication unit 550b is connected to the home information panel 400 installed inside the facility 110 by a cable or the like, and communicates wired with the home information panel 400 via the cable. The second communication unit 550b may communicate wirelessly with the home information panel 400.

[0027] In such a configuration, the control unit 540 executes control for connecting the first communication unit 550a and the second communication unit 550b. The control includes call control such as SIP (Session Initiation Protocol). For example, when the first communication unit 550a receives a call request, a video signal, and an audio signal from the common entrance device 200, the control unit 540 transmits the call request, the video signal, and the audio signal received by the first communication unit 550a from the second communication unit 550b to the house information panel 400. At this time, the control unit 540 may transfer the signals such as the call request, the video signal, and the audio signal as they are, or may transfer them after modifying the format of the signal. Furthermore, the control unit 540 may generate the video signal and the audio signal by decoding and then re-encoding the video signal and the audio signal, and then transfer them. At this time, if the received video signal and the audio signal contain an error, the error may be corrected, and the coding rate in the coding may be changed. Return to FIG. 1.

[0028] The home information panel 400 is installed in the facility 110, and is also called a dwelling unit unit, a dwelling unit terminal, a room master unit, a home master unit, or an information terminal. Fig. 2(c) 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. The processing unit 410 includes a microphone 414, a speaker 416, a monitor 418, and an IF unit 420.

[0029] The communication unit 450 is connected to the entrance device 500 by a cable or the like, and communicates with the second communication unit 550b of the entrance device 500 via the cable. The communication unit 450 may communicate wirelessly with the second communication unit 550b. The communication unit 450 receives a call request, a video signal, and an audio signal from the entrance device 500. The call request, the video signal, and the audio signal from the entrance device 500 can also be called a call request, the video signal, and the audio signal from the common entrance device 200. The control unit 440 is connected to the communication unit 450, and the control unit 440 controls the operation of the house information panel 400. The IF unit 420 and the operation unit 430 are connected to the control unit 440, and the microphone 414, the speaker 416, and the monitor 418 are connected to the IF unit 420. Here, the microphone 414, speaker 416, IF section 420, and operation section 430 are configured similarly to the microphone 214, speaker 216, IF section 220, and operation section 230. The monitor 418 displays the image captured by the imaging section 212 of the common entrance apparatus 200.

[0030] 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 causes the speaker 416 to output a ring tone via the IF unit 420. Subsequently, the control unit 440 causes the monitor 418 to display an image reproduced from the video signal via the IF unit 420, and causes the speaker 416 to output an audio reproduced from the audio signal via the IF unit 420. 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 transmit a response signal to the entrance apparatus 500.

[0031] When the second communication unit 550b of the entrance device 500 in Fig. 2(b) receives a response signal from the house information panel 400, the first communication unit 550a transmits the response signal to the common entrance device 200. When the communication unit 250 of the common entrance device 200 in Fig. 2(a) receives the response signal, the common entrance device 200 and the house information panel 400 are connected via the entrance device 500. As a result, a video signal is transmitted from the communication unit 250 to the communication unit 450 via the first communication unit 550a and the second communication unit 550b, and an audio signal is communicated between the communication unit 250 and the communication unit 450 via the first communication unit 550a and the second communication unit 550b, thereby executing a call between the visitor operating the common entrance device 200 and the resident operating the house information panel 400.

[0032] That is, the first communication unit 550a and the second communication unit 550b of the entrance device 500 perform communication between the common entrance device 200 and the house information panel 400 for a visitor call (hereinafter referred to as "communication within the collective facility"). This communication within the collective facility includes communication of a video signal from the common entrance device 200, that is, communication of images or videos captured by the imaging unit 212. Images or videos include still images and frame-by-frame images. Hereinafter, these may be collectively referred to as images.

[0033] When a resident decides to unlock the electric lock 300 through a call with a visitor, the resident inputs an unlocking command by operating the operation unit 430 of the home information panel 400 in Fig. 2(c). When the operation unit 430 receives an unlocking command from the resident, the control unit 440 causes the communication unit 450 to transmit an unlocking signal including the unlocking command to the entrance device 500. The unlocking signal can be said to be a signal for unlocking the electric lock 300 of the common entrance.

[0034] When the second communication unit 550b of the entrance device 500 in Fig. 2(b) receives an unlock signal from the home information panel 400, the first communication unit 550a transmits the unlock signal to the common entrance device 200. When the communication unit 250 of the common entrance device 200 in Fig. 2(a) receives the unlock signal, the control unit 240 causes the communication unit 250 to transmit an unlock instruction indicated by the unlock signal (hereinafter referred to as an "unlock instruction") to the electric lock 300. The electric lock 300 in Fig. 1 is capable of wireless communication compatible with a wireless communication system, and wirelessly communicates with the common entrance device 200. When the electric lock 300 receives the unlock instruction from the common entrance device 200, it unlocks.

[0035] The electric lock 300 automatically locks a certain period of time after being unlocked. The resident may also input a locking instruction by operating the operation unit 430 of the home information panel 400 in FIG. 2(c). When the operation unit 430 receives a locking instruction from the resident, the control unit 440 causes the communication unit 450 to transmit an unlocking signal including a locking instruction to the entrance device 500. The locking signal is transmitted from the entrance device 500 to the common entrance device 200 in the same manner as the unlocking signal, and the locking instruction is transmitted from the common entrance device 200 to the electric lock 300 in the same manner as the unlocking instruction. When the electric lock 300 receives the locking instruction, it locks.

[0036] (2) Intra-facility communications 2(b), when a visitor operates operation unit 530 of entrance apparatus 500, operation unit 530 outputs a call request to control unit 540. When operation unit 530 is operated by a visitor, processing unit 510 operates. Imaging unit 512 outputs a video signal capturing an image of the visitor to control unit 540 via IF unit 520, and microphone 514 outputs an audio signal capturing the visitor's voice to control unit 540 via IF unit 520. Speaker 516 reproduces and outputs the audio signal received from control unit 540 via IF unit 520.

[0037] The control unit 540 controls the operation of the entrance device 500 in addition to controlling the above-mentioned communication. When the control unit 540 receives a call request from the operation unit 530, the control unit 540 transmits the call request, the video signal from the imaging unit 512, and the audio signal from the microphone 514 from the second communication unit 550b to the house information panel 400. At that time, the control unit 540 generates information for determining whether the call request, etc. is obtained from the first communication unit 550a or from the IF unit 520 and the operation unit 530 (hereinafter referred to as "discrimination information"). When the call request, etc. is obtained from the first communication unit 550a, it corresponds to the above-mentioned intra-facility communication. On the other hand, when the call request, etc. is obtained from the IF unit 520 and the operation unit 530, it corresponds to communication for a visitor call between the entrance device 500 and the house information panel 400 (hereinafter referred to as "intra-facility communication").

[0038] The second communication unit 550b transmits a call request, a video signal, and an audio signal from the control unit 540 to the house information panel 400. At that time, the second communication unit 550b also transmits discrimination information. In the above-mentioned collective facility communication, the discrimination information indicates collective facility communication, and in the intra-facility communication here, the discrimination information indicates intra-facility communication. After the second communication unit 550b completes the connection with the entrance device 500, it transmits a video signal to the entrance device 500 and transmits and receives an audio signal thereto.

[0039] 2(c) is the same as in the case of intra-facility communication, but the control unit 440 determines whether it is intra-facility communication or intra-facility communication based on the determination information received by the communication unit 450. If it is determined to be intra-facility communication, the control unit 440 executes (1) processing for intra-facility communication. If it is determined to be intra-facility communication, the control unit 440 executes (1) processing similar to intra-facility communication, but the final target of communication is the entrance device 500 rather than the common entrance device 200.

[0040] That is, intra-facility communication is performed by second communication unit 550b of entrance apparatus 500. This intra-facility communication includes communication of a video signal from entrance apparatus 500, that is, communication of an image captured by imaging unit 512.

[0041] (3) Wireless communication settings As described above, the first communication unit 550a of the entrance apparatus 500 performs wireless communication with the common entrance apparatus 200. To achieve this, the first communication unit 550a needs to be set in advance for wireless communication with the common entrance apparatus 200. When the wireless communication system is a wireless LAN, the information to be set in the first communication unit 550a is the SSID of the communication unit 250 of the common entrance apparatus 200. The information may also include the device ID, MAC address, and IP address of the entrance apparatus 500, that is, the communication information described above. Generally, when setting such information in a device, the device needs a user interface such as a keyboard. However, the entrance apparatus 500 does not have such a user interface. In such a situation, the following process is performed to execute the setting in the first communication unit 550a.

[0042] The contractor has a terminal device (not shown) such as a smartphone, tablet terminal, or PC, and operates the terminal device to display on a screen two-dimensional information corresponding to the information to be set in the first communication unit 550a of the entrance device 500. The information is the SSID of the communication unit 250 as described above, and may also include communication information of the entrance device 500. The two-dimensional information is, for example, a QR (Quick Response) code (registered trademark). Since a known technology may be used to generate two-dimensional information in the terminal device reflecting the information, a description thereof will be omitted here.

[0043] By operating the operation unit 230 in the entrance device 500 in FIG. 2(b) in a manner different from that of a call, the operation unit 230 accepts an input for starting imaging of the operation unit 230. An operation in a manner different from that of a call is, for example, an operation of pressing the operation unit 230 for a long period of time of 10 seconds or more, or an operation of pressing the operation unit 230 a predetermined number of times or more within a predetermined time. The operation unit 530 corresponds to an input unit, and when it accepts an input for starting imaging, it notifies the control unit 540 of the input for starting imaging. When the control unit 540 accepts the notification, it causes the setting unit 542 to start a 2D information reading mode and causes the imaging unit 512 to start imaging via the IF unit 520. At that time, the construction company places the 2D information displayed on the screen of the terminal device in front of the imaging unit 512. The imaging unit 512 starts imaging the 2D information in response to an instruction from the control unit 540, and outputs the image of the captured 2D information to the control unit 540 via the IF unit 520.

[0044] When the setting unit 542 of the control unit 540 activates the 2D information reading mode, it accepts an image of the 2D information captured by the imaging unit 512. The setting unit 542 acquires information contained in the 2D information from the image of the 2D information. Since a known technique may be used to acquire the information, a description thereof will be omitted here. The acquired information is the SSID of the communication unit 250 described above, but may also include communication information of the entrance apparatus 500. The setting unit 542 sets the acquired information in the first communication unit 550a. This corresponds to the first communication unit 550a executing settings for performing wireless communication with the common entrance apparatus 200.

[0045] By performing such settings, wireless communication between the entrance apparatus 500 and the common entrance apparatus 200 becomes possible. In this state, the entrance apparatus 500 may further execute the following process. The first communication unit 550a measures the state of wireless communication with the common entrance apparatus 200. Measuring the state of wireless communication means checking the communication quality, and includes, for example, measuring the reception power, the error rate, and the interference power. The control unit 540 accepts the measurement result in the first communication unit 550a, and causes the second communication unit 550b to transmit the measurement result to the house information panel 400 as information on the state of wireless communication between the first communication unit 550a and the common entrance apparatus 200 (hereinafter referred to as "measurement information"). The communication unit 450 of the house information panel 400 in FIG. 2(c) receives the measurement information from the entrance apparatus 500. The control unit 440 causes the monitor 418 to display the measurement information.

[0046] Furthermore, the first communication unit 550a may report the result of pairing with the common entrance apparatus 200 set by the setting unit 542 to the control unit 540. The control unit 540 causes the second communication unit 550b to transmit information including the result of pairing (hereinafter referred to as the "pairing result") to the home information panel 400. The communication unit 450 of the home information panel 400 in FIG. 2(c) receives the pairing result from the entrance apparatus 500. The control unit 440 causes the monitor 418 to display the pairing result.

[0047] The subject of the device, system, or method in the present disclosure includes a computer. The computer executes a program to realize the function of the subject of the device, system, or method in the present disclosure. The computer includes a processor that operates according to a program as a main hardware configuration. The type of the processor does not matter as long as it can realize the function by executing the program.

[0048] The operation of the intercom system 1000 configured as above will be described. Fig. 4 is a sequence diagram showing the unlocking procedure by the intercom system 1000. When the common entrance device 200 accepts a call operation (S10), it transmits a call request to the entrance device 500 (S12), and the entrance device 500 transmits the call request to the house information panel 400 (S14). The house information panel 400 outputs a ring tone (S16). The common entrance device 200 transmits a video signal to the entrance device 500 (S18), and the entrance device 500 transmits the video signal to the house information panel 400 (S20). The house information panel 400 displays the video (S22) and accepts a response operation (S24). The house information panel 400 transmits a response signal to the entrance device 500 (S26), and the entrance device 500 transmits the response signal to the common entrance device 200 (S28).

[0049] The common entrance device 200 transmits a video signal to the entrance device 500 (S30), and the entrance device 500 transmits the video signal to the home information panel 400 (S32). The common entrance device 200 transmits an audio signal to the entrance device 500 (S34), and the entrance device 500 transmits the audio signal to the home information panel 400 (S36). When the home information panel 400 receives an unlocking operation (S38), it transmits an unlocking signal to the entrance device 500 (S40). The entrance device 500 transmits an unlocking signal to the common entrance device 200 (S42), and the common entrance device 200 transmits an unlocking instruction to the electric lock 300 (S44). When the home information panel 400 receives an end of the operation (S46), it transmits an end signal to the entrance device 500 (S48). The entrance device 500 transmits an end signal to the common entrance device 200 (S50).

[0050] According to this embodiment, the first communication unit 550a executes the setting for executing the wireless communication with the common entrance apparatus 200 based on the information acquired by the imaging unit 512, so that the wireless communication used in the intercom system 1000 can be easily set even if the entrance apparatus 500 does not have an interface for setting. Also, the setting for executing the wireless communication is executed based on the information acquired by the imaging unit 512 by imaging the two-dimensional information, so that the setting can be easily performed. Also, since an input for starting the imaging of the imaging unit 512 is accepted, calling and setting can be performed separately. Also, since information on the state of the wireless communication between the first communication unit 550a and the common entrance apparatus 200 is transmitted, the communication quality can be confirmed in advance. Also, since the result of pairing with the common entrance apparatus 200 based on the setting of the setting unit 542 is transmitted, it can be confirmed whether the pairing is successful or not.

[0051] In addition, since wireless communication is performed between the common entrance device 200 and the entrance device 500, an increase in the number of steps in construction when connecting devices in the collective facility 100 can be suppressed. Since wireless communication is performed between the common entrance device 200 and the entrance device 500 installed outside the facility 110, the influence of obstacles such as walls can be reduced. Furthermore, since the influence of obstacles is reduced, deterioration of communication quality can be suppressed. Furthermore, since wired communication is performed between the entrance device 500 and the house information panel 400, communication between the common entrance device 200 and the house information panel 400 can be performed via the entrance device 500. Furthermore, since wired communication is performed between the entrance device 500 and the house information panel 400, the influence of obstacles such as walls can be reduced. Furthermore, since intra-facility communication is performed for calls between the entrance device 500 and the house information panel 400, and intra-facility communication is performed for calls between the common entrance device 200 and the house information panel 400, an increase in the number of steps in construction when connecting devices can be suppressed while deterioration of communication quality can be suppressed.

[0052] Furthermore, since intra-facility communication includes communication of images captured by the imaging unit 512, and collective intra-facility communication includes communication of images captured by the imaging unit 212, the image at the entrance device 500 and the image at the common entrance device 200 can be confirmed on the house information panel 400. Furthermore, since information for distinguishing between intra-facility communication and collective intra-facility communication is transmitted to the house information panel 400, processing in the house information panel 400 can be simplified. Furthermore, since a signal for unlocking the electric lock at the common entrance is received from the house information panel 400 and a signal for unlocking the electric lock 300 at the common entrance is transmitted, the unlocking signal can be relayed.

[0053] An outline of one aspect of the present disclosure is as follows: An entrance device (500) according to one aspect of the present disclosure is used in an intercom system (1000) of a collective facility (100) in which multiple facilities (110) are gathered, and is installed at the entrance of the facility (110), and includes a first communication unit (550a) that performs wireless communication, a second communication unit (550b) that communicates with an information terminal (400) installed inside the facility (110), and a setting unit (542) that performs setting for the first communication unit (550a) to perform wireless communication with a common entrance device (200) installed at the common entrance of the collective facility (100) based on information acquired by one or more of the first communication unit (550a), the second communication unit (550b), and the imaging unit (512) of the entrance device (500).

[0054] The setting unit (542) may execute settings for the first communication unit (550a) to execute wireless communication with the common entrance apparatus (200) based on information acquired by the imaging unit (512) capturing two-dimensional information.

[0055] The image capturing device may further include an input unit that receives an input for starting imaging by the imaging unit (512).

[0056] The second communication unit (550b) may transmit information regarding the state of wireless communication between the first communication unit (550a) and the common entrance apparatus (200).

[0057] The second communication unit (550b) may transmit the result of pairing with the common entrance apparatus (200) set by the setting unit (542).

[0058] Another aspect of the present disclosure is a setting method for an entrance device (500) used in an intercom system (1000) of a collective facility (100) where multiple facilities (110) are gathered and installed at the entrance of the facility (110), the setting method including the steps of performing wireless communication, communicating with an information terminal (400) installed inside the facility (110), and performing settings for the entrance device (500) to perform wireless communication with a common entrance device (200) installed at the common entrance of the collective facility (100) based on one or more of information acquired by wireless communication, information acquired by communication, and information acquired by an imaging unit (512) of the entrance device (500).

[0059] Example 2 Next, a second embodiment will be described. As with the first embodiment, the second embodiment relates to an intercom system 1000 installed in the collective facility 100, and in particular to settings for an entrance device 500 that communicates wirelessly with the common entrance device 200. In the first embodiment, settings are made by capturing two-dimensional information using the imaging unit 512 of the entrance device 500, but in the second embodiment, settings are made by wireless communication from a terminal device. The common entrance device 200, the entrance device 500, and the house information panel 400 in the second embodiment are of the same type as those in Figs. 2(a)-(c). Here, the differences from the first embodiment will be mainly described.

[0060] FIG. 5 shows the configuration of the intercom system 1000. In the intercom system 1000, a terminal device 600 is added to the configuration of FIG. 1. The terminal device 600 is a communication device such as a smartphone, a tablet terminal, or a PC, similar to the terminal device in the first embodiment. The terminal device 600 is possessed by a construction contractor. The terminal device 600 is capable of performing wireless communication corresponding to the wireless communication system, and wirelessly communicates with the entrance device 500. For example, ad-hoc communication is used for communication between the terminal device 600 and the entrance device 500. The terminal device 600 can be said to be a setting terminal different from the common entrance device 200.

[0061] The contractor operates the terminal device 600 to input information to be set in the first communication unit 550a of the entrance device 500, and transmits the information to the entrance device 500. The first communication unit 550a of the entrance device 500 in FIG. 2(b) receives information from the terminal device 600 by ad-hoc communication. The first communication unit 550a outputs the received information to the control unit 540. The setting unit 542 acquires information from the first communication unit 550a. The acquired information is the SSID of the communication unit 250 described above, but may include communication information of the entrance device 500. The setting unit 542 sets the acquired information in the first communication unit 550a. This corresponds to the first communication unit 550a executing settings for performing wireless communication with the common entrance device 200.

[0062] In the second embodiment, the following process may be further executed as in the first embodiment. The first communication unit 550a measures the state of wireless communication with the common entrance apparatus 200. Measuring the state of wireless communication means checking the communication quality, and includes, for example, measuring the reception power, the error rate, and the interference power. The control unit 540 receives the measurement result in the first communication unit 550a, and causes the first communication unit 550a to transmit the measurement result to the terminal device 600 as information on the state of wireless communication between the first communication unit 550a and the common entrance apparatus 200 (hereinafter, referred to as "measurement information"). The terminal device 600 receives the measurement information from the entrance apparatus 500. The terminal device 600 causes the measurement information to be displayed on a screen.

[0063] Furthermore, first communication unit 550a may report the result of pairing with the common entrance apparatus 200 set by setting unit 542 to control unit 540. Control unit 540 causes first communication unit 550a to transmit information including the result of pairing (hereinafter referred to as "pairing result") to terminal device 600. Terminal device 600 receives the pairing result from entrance apparatus 500. Terminal device 600 causes the pairing result to be displayed on a screen.

[0064] The setting of the first communication unit 550a in the entrance apparatus 500 may be performed from the house information panel 400 via the second communication unit 550b. In other words, the setting unit 542 performs setting for the first communication unit 550a to perform wireless communication with the common entrance apparatus 200 based on information acquired by one or more of the first communication unit 550a, the second communication unit 550b, and the imaging unit 512.

[0065] According to this embodiment, the first communication unit 550a executes the setting for executing the wireless communication with the common entrance apparatus 200 based on the information acquired by one or more of the first communication unit 550a and the second communication unit 550b, so that the setting of the wireless communication used in the intercom system 1000 can be simplified even if the entrance apparatus 500 does not have an interface for setting. Also, since the first communication unit 550a executes the setting for executing the wireless communication based on the information acquired from the terminal apparatus 600, the setting can be simplified. Also, since information on the state of the wireless communication between the first communication unit 550a and the common entrance apparatus 200 is transmitted, the communication quality can be confirmed in advance. Also, since the result of pairing with the common entrance apparatus 200 based on the setting of the setting unit 542 is transmitted, it can be confirmed whether the pairing has been successful or not.

[0066] An outline of one aspect of the present disclosure is as follows: The setting unit (542) may execute settings for the first communication unit (550a) to execute wireless communication with the common entrance apparatus (200) based on information acquired by the first communication unit (550a) from a setting terminal different from the common entrance apparatus (200).

[0067] The first communication unit (550a) may transmit information regarding the state of wireless communication between the first communication unit (550a) and the common entrance apparatus (200) to the setting terminal.

[0068] The first communication unit (550a) may transmit the result of pairing with the common entrance apparatus (200) set by the setting unit (542) to the setting terminal.

[0069] The present disclosure has been described above based on the embodiments. These embodiments are merely illustrative, and it will be understood by those skilled in the art that various modifications are possible in the combination of each component or each treatment process, and that such modifications are also within the scope of the present disclosure.

[0070] In the first and second embodiments, the common entrance apparatus 200 and the entrance apparatus 500 are directly connected by wireless LAN. However, this is not limited to this, and for example, the first communication unit 550a of the entrance apparatus 500 may wirelessly communicate with the common entrance apparatus 200 via a wireless access point. According to this modification, even if the scale of the collective facility 100 is large, deterioration of the quality of wireless communication can be suppressed. [Explanation of symbols]
