Description

[Technical Field]

[0001] The present disclosure relates to intercom systems. [Background technology]

[0002] In recent years, there has been an increase in a delivery method known as drop-off delivery, in which delivery is completed by leaving the package at a designated location when the recipient of the package is not at the delivery destination residence, etc. In delivery services using drop-off delivery, various technologies have been proposed for automatically unlocking auto-lock doors installed at the entrances of apartment buildings, etc., for visitors who are permitted to enter the apartment buildings, etc. (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-14729 [Patent Document 2] Japanese Patent Publication No. 2020-53047 Summary of the Invention [Problem to be solved by the invention]

[0004] Being able to enjoy delivery services from a service provider even when the resident is not at home is convenient for both the resident and the service provider. However, since the resident cannot confirm whether someone has entered their apartment building or other property when they are not at home, it is desirable for the system to have better security than conventional intercom systems.

[0005] The present disclosure aims to improve the security of intercom systems. [Means for solving the problem]

[0006] In order to achieve the above object, the intercom system of the present disclosure comprises: a handset for a visitor to call a resident and talk to the visitor; a room base unit for a resident to answer a call from the handset; and a control unit for controlling the operation of the handset and the room base unit. An intercom system comprising: The slave unit has a display unit capable of displaying at least a call operation unit for calling the resident, and an information input unit for inputting delivery information that proves that a service provider has come to deliver a package, the delivery information including at least package information that identifies the package to be delivered by the service provider, and room information that identifies a room at the destination; The control unit is configured to verify that the delivery information input to the information input unit matches the delivery information previously recorded in the server, and then accept the input of the room information.

[0007] According to the above configuration, unless the visitor checks the baggage information, the visitor cannot input the room information and the room cannot be identified for calling. This prevents a third party from calling the room by pretending to be a service provider. This improves the security of the intercom system. [Effects of the Invention]

[0008] According to the present disclosure, the security of an intercom system can be improved. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an intercom system according to an embodiment of the present disclosure will be described with reference to the drawings. Fig. 1 is a configuration diagram showing an intercom system 1 according to this embodiment. As shown in Fig. 1, the intercom system 1 includes a collective entrance unit 10 (an example of a slave unit), a server 20, a room master unit 30, an entrance slave unit 40, a management room master unit 50, and a controller 60 (an example of a control unit). The intercom system 1 is an intercom system that is applied to, for example, an apartment building or other collective housing complex.

[0011] The collective entrance unit 10, server 20, room master unit 30, and management room master unit 50 are connected to the control unit 60 via an intercom line L, which communicates according to a general-purpose protocol. The entrance slave unit 40 is also connected to the room master unit 30 via the intercom line L. In this example, the intercom line L is configured with a LAN (Local Area Network) cable. However, the intercom line L may also be configured with a dedicated line.

[0012] The collective entrance device 10 is installed at the collective entrance (entrance), which is a common space of the apartment building. The collective entrance device 10 includes a display unit 11, a communication unit 12, and a camera 13 (an example of an imaging means).

[0013] The server 20 has a function of creating a data table based on the received data. For example, the server 20 receives data such as package information set by a service provider from an external server 70 (described later), and creates a data table based on the package information. The package information and the data table will be described in detail later.

[0014] The room master unit 30 is installed in each dwelling unit of the apartment building in which the intercom system 1 is installed. The room master unit 30 includes a display unit 31 (an example of a second display unit), an operation unit 32, and a call unit 33. The display unit 31 is capable of displaying various information and accepting user operations, and may be a touch display, for example. Images of visitors captured by the camera 13 of the collective entrance unit 10 are displayed on the display unit 31. The operation unit 32 is operated when responding to a call from the collective entrance unit 10 or the management room master unit 50, or when calling the management room master unit 50. The operation unit 32 is composed of, for example, operation buttons displayed on the touch display that is the display unit 31. The call unit 33 is used by the resident to make a call with the collective entrance unit 10 or the management room master unit 50, and includes a microphone and a speaker.

[0015] The entrance slave unit 40 is installed at the entrance of each dwelling unit. The entrance slave unit 40 is equipped with a call button 41 that allows a visitor to call the resident, a communication unit 42 that allows the visitor to talk to the resident, and a camera 43 that can capture an image of the visitor. The image of the visitor captured by the camera 43 is displayed on the display unit 31 of the room master unit 30.

[0016] The control room master unit 50 is installed in the control room of the apartment building. The control room master unit 50 includes a display unit 51 that displays images captured by the camera 13 of the apartment building entrance unit 10, an operation unit 52 that is operated to call a specific room, and a communication unit 53 that allows the manager to communicate with residents or visitors.

[0017] The control unit 60 controls the operation of the collective entrance unit 10, the server 20, the room master unit 30, the management room master unit 50, etc. For example, the control unit 60 controls the call status from the collective entrance unit 10 to the room master unit 30. The control unit 60 is connected to an external server 70 and a door control device 80 via a network N.

[0018] The controller 60 may include, for example, at least one microcontroller including one or more processors and other electronic circuits including active and passive elements such as transistors. The controller 60 may be configured with multiple CPU cores. The controller 60 may be, for example, a microprocessing unit (MPU), a graphics processing unit (GPU), and / or a tensor processing unit (TPU). The GPU may be configured with multiple GPU cores. The controller 60 may also be configured with hardware resources including integrated circuits such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA). The controller 60 may also be configured with a combination of at least one microcontroller and an integrated circuit.

[0019] The external server 70 is, for example, a server installed at a business office of a service provider. An example of a service provider is a delivery company. The external server 70 has a function of collecting package information set by the service provider. Package information is, for example, information for identifying a delivery item. Examples of package information include a tracking number, a control number, and a waybill (slip) number of the delivery item. In this example, the package information is described as a tracking number.

[0020] When the service provider receives a delivery addressed to a resident from a third party (sender), it determines a tracking number. The service provider informs the sender of the tracking number that it has set. The sender then informs the resident, who is the destination (recipient), of the tracking number. The resident then transmits the tracking number to an external server 70 together with a resident ID that identifies the resident. Upon receiving the resident ID and tracking number, the external server 70 transmits this information via network N to the controller 60 of the intercom system 1 of the apartment building that corresponds to the resident ID.

[0021] The door control device 80 is a device for controlling the locking and unlocking of a door 90 installed at the entrance of the apartment building to which the intercom system 1 is applied. The door control device 80 unlocks the door 90 based on an unlock request signal transmitted from the controller 60.

[0022] A terminal T owned by a resident may be connected to the network N. The controller 60 may transmit information about the intercom system 1 to the terminal T through the network N.

[0023] FIG. 2 is a functional block diagram of the collective entrance unit 10, the server 20, the room master unit 30, and the controller 60 of the intercom system 1. As shown in FIG. As shown in FIG. 2, the collective entrance unit 10 includes a display unit 11, a communication unit 12, and a camera 13, as well as a collective entrance unit CPU (Central Processing Unit) 14 and a communication interface (IF) 15.

[0024] The display unit 11 is configured to be able to display a call operation unit 111 and an information input unit 112. That is, the display unit 11 also functions as an input unit for accepting various operations from a user (for example, a visitor).

[0025] The call operation unit 111 is an operation unit that a visitor operates when calling a resident. The call operation unit 111 is configured with, for example, a numeric keypad and a call button displayed on the display unit 11.

[0026] The information input unit 112 is configured to allow delivery information and room information to be input.

[0027] The delivery information includes package information. Package information is information that identifies packages delivered by a service provider. Package information may be a slip number assigned to packages delivered by a service provider or product tracking information assigned by an online e-commerce service.

[0028] The delivery information may include at least one of service information associated with the service provider and provider information identifying the service provider. The service information may be information identifying whether the delivery is made using a delivery service supported by the intercom system 1. The provider information may be the name of the service provider that delivers the package using the delivery service or a code identifying the service provider.

[0029] The room information may include the address of the resident who will be using the delivery service to receive delivery services.

[0030] The information input unit 112 is allowed to change its display to accommodate the input of each piece of information. For example, when receiving service information, the information input unit 112 may be displayed as a button for selecting the type of service provider. When receiving provider information, the information input unit 112 may be displayed as a button indicating whether the service provider belongs to the service provider.

[0031] The collective entrance device CPU 14 performs processing to control each part of the collective entrance device 10. The communication IF 15 forms a bidirectional signal transmission path between the collective entrance device CPU 14 and the intercom line L. This forms a signal transmission path between the collective entrance device CPU 14 and the control device 60 via the communication IF 15.

[0032] 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 memory unit 36. The master unit CPU 34 performs processing to control each unit 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 memory unit 36 ​​stores control information and the like for the room master unit 30. The memory unit 36 ​​also stores image data captured by the camera 13 of the collective entrance unit 10 or the camera 43 of the entrance slave unit 40 and transmitted from the collective entrance unit 10 or the entrance slave unit 40.

[0033] The control unit 60 includes a control unit 61 and a memory unit 62. The control unit 61 is capable of communicating with the collective 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, etc. The memory unit 62 stores communication information, control information, etc. In this example, the memory unit 62 stores a call table 62a in which the room number of each dwelling unit in the apartment building is recorded in association with a room master unit ID that can identify the room master unit 30 of each dwelling unit.

[0034] The control unit 61 receives a signal including information about the room number input via the call operation unit 111 of the collective 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 room number input via the call operation unit 111. The control unit 61 then transmits a call signal to the identified room master unit 30.

[0035] Furthermore, the control unit 61 receives information including a resident ID and package information (tracking number) linked to the resident ID from the external server 70, stores this information in the memory unit 62, and transmits it to the server 20. Note that the control unit 61 may transfer the information received from the external server 70 to the server 20 without storing it in the memory unit 62.

[0036] The server 20 includes a generating unit 21 and a storage unit 22. The generation unit 21 is capable of generating a predetermined data table 22a based on information including a resident ID and a tracking number received from the external server 70 via the control device 60. The storage unit 22 stores the data table 22a generated by the generation unit 21.

[0037] In addition, if it is determined based on the service information included in the delivery information provided by the external server 70 that the delivery was not made using a delivery service, the memory unit 22 does not need to store the delivery information for the package.

[0038] FIG. 3 shows an example of data table 22a stored in storage unit 22. As shown in FIG. 3, data table 22a records a resident ID, a room management number, a business operator ID, and a slip ID based on delivery information transmitted from external server 70. The resident ID, room management number, business operator ID, and slip ID are associated with each package delivered by the delivery service. For example, business operator ID: A and tracking number: 101-***-*** are stored in association with resident ID: U1 and room management number: 101 corresponding to resident ID: U1. Furthermore, business operator ID: B and tracking number: 105-***-*** are stored in association with resident ID: U2 and room number: 201 corresponding to resident ID: U2.

[0039] (Intercom System 1 Operation) Next, the operation of the intercom system 1 when a visitor, a service provider, visits an apartment building to which the intercom system 1 is applied to deliver a package addressed to a resident of the apartment building will be described with reference to FIGS. 4 to 9. FIG. 4 is a flowchart illustrating an example of the operation of the collective entrance unit 10, the control unit 60, the room master unit 30, and the door control device 80 in the intercom system 1. FIG. 5 is a diagram showing an example of an initial screen 200 displayed on the display unit 11 of the collective entrance unit 10. FIG. 6 is a diagram showing an example of a service selection screen 210 displayed on the display unit 11. FIG. 7 is a diagram showing an example of a package information input screen 220 displayed on the display unit 11. FIG. 8 is a diagram showing an example of a call operation screen 230 displayed on the display unit 11. FIG. 9 is a diagram showing an example of an unlocking operation screen 240 displayed on the display unit 11.

[0040] As shown in FIG. 5, when a service provider arrives at the entrance of an apartment building with a delivery item, an initial screen 200 is displayed on the display unit 11 of the apartment building entrance device 10. The initial screen 200 displays a "Room Call" button 201 for calling each dwelling unit in the apartment building, a "Control Room Call" button 202 for calling the control room, a "Resident Service" button 203 for executing various services for residents, and a "Delivery Service" button 204 for executing services for service providers such as couriers. The "Delivery Service" button 204 is an example of a display mode of the information input unit 112, as it allows service information to be input. Whether or not the "Delivery Service" button 204 is operated is an example of whether or not service information has been input.

[0041] 4, it is assumed that the service provider operates the "Delivery Service" button 204 displayed on the display unit 11 of the collective entrance device 10. When the operation of the "Delivery Service" button 204 is accepted (step S101), the collective entrance device CPU 14 transmits an operation acceptance signal to the control device 60 (step S102). Upon receiving the operation acceptance signal, the control unit 61 of the control device 60 transmits a display signal relating to the service selection screen 210 to the collective entrance device 10 (step S103).

[0042] Upon receiving the display signal for the service selection screen 210, the collective entrance device CPU 14 of the collective entrance device 10 causes the display unit 11 to display the service selection screen 210 (step S104). The service selection screen 210 is configured so that business information can be input, and is therefore an example of a display mode for the information input unit 112. As shown in Fig. 6, the service selection screen 210 displays, for example, display fields 211A to 211E for the company names or service names of service businesses, and an "End" button 212.

[0043] Next, the service provider selects a predetermined display field corresponding to the company (service) to which the service provider belongs from among the multiple display fields 211A-211E displayed on the service selection screen 210, and then operates the "End" button 212. For example, the service provider selects display field 211A from among the display fields 211A-211E by touch operation. When each of the display fields 211A-211E receives an operation by the service provider on one of the display fields 211A-211E (information input unit 112) (step S105), the collective entrance device CPU 14 transmits an operation acceptance signal including information on the selected display field to the control device 60 (step S106). For example, when the service provider selects display field 211A by touch operation, the collective entrance device CPU 14 transmits an operation acceptance signal including information corresponding to "Company: A" to the control device 60. The control unit 61, which has received the operation acceptance signal, transmits a display signal related to the package information input screen 220 to the collective entrance device 10 (step S107).

[0044] Upon receiving the display signal related to the package information input screen 220, the collective entrance device CPU 14 displays the package information input screen 220 on the display unit 11 (step S108). As shown in Fig. 8, the package information input screen 220 displays, for example, a numeric keypad button 221 for inputting a slip number, a "decide" button 222, an "end" button 223, and the like. These buttons 221 to 223 included in the package information input screen 220 function as the information input unit 112.

[0045] Next, the service provider uses the numeric keypad buttons 221 on the package information input screen 220 to input the slip number and the like as package information, and then operates the "OK" button 222. Upon receiving the input of package information and the operation of the "OK" button 222 (step S109), the collective entrance machine CPU 14 transmits an operation acceptance signal including the input package information to the control unit 60 as an unlock request (step S110). For example, if the service provider inputs the slip number "101-***-***" in step S109, the collective entrance machine CPU 14 transmits an operation acceptance signal including "101-***-***" to the control unit 60.

[0046] Next, upon receiving the operation acceptance signal, the control unit 61 verifies whether the delivery information entered by the visitor at the collective entrance device 10 matches the delivery information contained in the data table 22a stored in the memory unit 22 of the server 20 (step S111). For example, if the visitor enters "Company: A" (step S105) and "Invoice number: 101-***-***" (step S109), the data table 22a in the example of Fig. 3 stores data corresponding to "Company: A" and "Invoice number: 101-***-***", so the control unit 61 determines that the respective delivery information matches.

[0047] Next, if the delivery information included in the operation acceptance signal does not match the service number included in data table 22a (NO in step S111), control unit 61 determines that authentication has failed and sends a display signal for initial screen 200 to collective entrance device 10. At this time, collective entrance device 10 that has received the display signal for initial screen 200 may display a notification screen on display unit 11, before displaying initial screen 200, as notification information that authentication has failed, such as "Authentication has failed. Please try again by clicking the 'Delivery Service' button." If the delivery information does not match, control unit 61 may send an authentication failure signal to collective entrance device 10.

[0048] If the delivery information contained in the operation acceptance signal matches the delivery information contained in the data table 22a (YES in step S111), the control unit 61 determines that authentication of the delivery information entered up to this point has been successful, and sends a display signal regarding the call operation screen 230 to the collective entrance device 10 (step S112).

[0049] Upon receiving the display signal related to the call operation screen 230, the collective entrance device CPU 14 displays the call operation screen 230 on the display unit 11 (step S113). As shown in Fig. 7, the call operation screen 230 displays, for example, a numeric keypad button 231 for inputting the room number of each dwelling unit, a "Call" button 232, and the like. These buttons 231 and 232 included in the call operation screen 230 function as the call operation unit 111. The numeric keypad button 231 is configured to allow input of room information, and therefore also functions as the information input unit 112.

[0050] Next, the service provider inputs the room number of the room to which the delivery is to be made using the numeric keypad buttons 231 displayed on the call operation screen 230, and then operates the "Call" button 232. Upon receiving the input of the room number using the numeric keypad buttons 231 and the operation of the "Call" button 232 (step S114), the collective entrance machine CPU 14 transmits an operation acceptance signal including information about the input room number to the control unit 60 (step S115). For example, if the service provider inputs the room number "101" on the call operation screen 230 and then operates the "Call" button 232, the collective entrance machine CPU 14 transmits an operation acceptance signal including information corresponding to the room number "101" to the control unit 60.

[0051] Next, the control unit 61 identifies the room master unit 30 associated with the room number included in the received operation acceptance signal from among the multiple room master units 30 installed in the apartment building, and generates a call signal for calling the identified room master unit 30 (step S116). The control unit 61 then transmits the call signal to the identified room master unit 30 (step S117). For example, the control unit 61 identifies the room master unit 30 in room 101 based on the information on the room number "101" included in the received operation acceptance signal, and generates a call signal for calling the room master unit 30. The call signal is then transmitted to the identified room master unit 30 in room 101.

[0052] Next, the room master unit 30 in Room 101, which has received the call signal from the control unit 61, outputs a call tone to notify the user that a visitor is calling from the common entrance (step S118). The operation of outputting a call tone in response to the call signal from the control unit 61 is referred to as a call operation.

[0053] Door 90 is unlocked when the resident answers the call and agrees to allow the visitor through. For example, when a call tone is being output from room master unit 30 in room 101 and the resident of room 101 uses room master unit 30 to answer the call, a response signal is sent from room master unit 30 to control unit 60. However, in this example, it is assumed that the service provider unlocks door 90 and performs delivery to a parcel because the resident is absent or does not answer, so a description of the operation of collective entrance unit 10 and control unit 60 when the resident answers the call will be omitted.

[0054] Next, the control unit 61 determines whether a certain time has elapsed since the room master unit 30 started to output a ring tone (step S119). This certain time may be, for example, 10 to 20 seconds, and preferably 15 to 17 seconds. The certain time may be changed depending on which of the display fields 211A to 211E was selected on the service selection screen 210 in step S105. For example, the certain time may be set differently depending on whether the display field 211A of the plurality of display fields 211A to 211E is selected or whether the display field 211B is selected. The control unit 61 stores information about the certain time individually set for each service provider in the storage unit 62, and can change the certain time based on the information in accordance with the type of information input unit 112 that accepted the operation in step S105. Note that the starting point for counting the elapsed time is not limited to the start of the ring tone output in the room master unit 30. For example, the time when the "call" button 222 is operated or when a call signal is sent to the specified room master unit 30 may be set as the starting point for counting the passage of a certain period of time.

[0055] If it is determined in step S119 that the certain time has not elapsed since the room master unit 30 started to output the call tone (NO in step S119), the control unit 61 repeats the operation of step S119 until the certain time has elapsed.If it is determined in step S119 that the certain time has elapsed since the room master unit 30 started to output the call tone (YES in step S119), the control unit 61 transmits a display signal for the unlocking operation screen 240 to the collective entrance unit 10 (step S120).

[0056] Upon receiving the display signal related to the unlocking operation screen 240, the multiple entrance device CPU 14 displays the unlocking operation screen 240 on the display unit 11 (step S121). As shown in Fig. 9, the unlocking operation screen 240 displays, for example, an "Unlock" button 241 and a message urging the user to operate the "Unlock" button 241, such as "No residents are currently present. Please press the unlock button to enter the door." The "Unlock" button 241 is an example of an unlocking operation unit.

[0057] Next, the service provider operates the "Unlock" button 241 displayed on the unlocking operation screen 240 (step S122). When the service provider operates the "Unlock" button 241 on the unlocking operation screen 240, the collective entrance device CPU 14 transmits an operation acceptance signal to the control device 60 (step S123).

[0058] Next, upon receiving the operation acceptance signal, control unit 61 generates an unlock instruction signal (step S124) and transmits it to door control device 80 (step S125). Then, upon receiving the unlock instruction signal, door control device 80 unlocks door 90 (step S126). This allows the service provider to enter the apartment building through door 90 and perform delivery work.

[0059] In step S111, if the delivery information input to the information input unit 112 matches the delivery information recorded on the server, the control unit 61 may cause the room master unit 30 to generate a display indicating that the package has been authenticated by the service provider. When notifying the room master unit 30, the control unit 61 may cause the display unit 31 of the room master unit 30 to display a screen indicating that the service provider has visited.

[0060] The control unit 61 may send a notification regarding the business information to the terminal T owned by the resident based on at least the business information input to the information input unit 112. At this time, the control unit may change the display content of the notification sent to the terminal T owned by the resident based on at least whether or not the "Delivery Service" button 204 has been operated. The notification may be, for example, a screen display indicating that the operation of the collective entrance device 10 has been accepted for a visitor who has input service information, business information, and room information.

[0061] FIG. 10 is a diagram showing an example of a notification displayed on terminal T. For example, if the visitor does not operate the "Delivery Service" button 204, the control unit 61 may determine that the visitor is not a service provider and may cause a display such as that shown in FIG. 10 to be displayed on terminal T owned by the resident. A display asking whether or not to unlock the door is generated on the display of terminal T. In this case, even if the resident is not in the room, the resident can choose whether or not to unlock the door by operating terminal T. The display shown in FIG. 10 may also display an image or video captured by camera 13 of the collective entrance machine 10.

[0062] FIG. 11 is a diagram showing another example of a notification displayed on terminal T. On the other hand, if a visitor operates the "Delivery Service" button 204, the control unit 61 may determine that the visitor is a service provider and cause a display such as that shown in FIG. 11 to be displayed on terminal T owned by the resident. In this case, since the service provider can unlock the door 90 by performing an appropriate operation, the display on terminal T does not generate a message asking whether to unlock the door, but simply displays the fact that "Company A has visited." The display shown in FIG. 11 may also display an image or video captured by camera 13 of the collective entrance machine 10.

[0063] With the intercom system 1 configured as described above, the verification of package information is performed before the input of room information. Therefore, if the package information is not input correctly, the input of room information will not be accepted, and the room cannot be identified for calling. This prevents a third party from calling a room by impersonating a service provider. This improves the security of the intercom system 1.

[0064] According to the intercom system 1 configured as described above, when the delivery information input to the information input unit 112 matches the delivery information recorded in the server 20, the control unit 61 generates a display on the room master unit 30 indicating that the package from the service provider has been authenticated. Therefore, the resident can see the display generated on the room master unit 30 and know that a legitimate service provider has come to deliver a legitimate package.

[0065] According to the intercom system 1 configured as described above, the control unit 61 causes the room master unit 30 to execute a call operation based on an input to the call operation unit 111. If there is no response to the call operation within a predetermined time, the control unit 61 causes the display unit 11 to display the "unlock" button 241, which is an unlock operation unit that causes the door control device 80 to unlock the door 90. This allows the service provider to visit a room in the apartment building even if the resident does not respond to the call.

[0066] According to the intercom system 1 configured as described above, the delivery information includes at least one of service information associated with the service provider and provider information that identifies the service provider. This allows verification based on multiple factors to confirm that a legitimate service provider has delivered a legitimate package, thereby improving the security of the intercom system 1.

[0067] According to the intercom system 1 configured as described above, the control unit 61 sends a notification regarding the provider information to the terminal T owned by the resident. This allows the resident to know which service provider has visited them even when they are not in their room.

[0068] According to the intercom system 1 configured as described above, the control unit 61 changes the display content of the notification sent to the terminal T owned by the resident based on at least whether service information has been input. Whether service information has been input determines whether the visitor is a general visitor or a service provider who has come to provide a service. By changing the display content of the notification sent to the terminal T owned by the resident based on at least whether service information has been input, the resident can know whether a general visitor or a service provider who has come to provide a service has visited their room, even when they are not in their room.

[0069] The present disclosure is not limited to the above-described embodiments and may be freely modified, improved, etc. The material, shape, dimensions, numerical values, form, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as the present disclosure can be achieved.

[0070] For example, in the intercom system 1 according to the present embodiment, the delivery information includes all of the service information, business information, and room information. However, the delivery information only needs to include information that proves that the service business has delivered the package, and at least one or all of the service information, business information, and room information do not necessarily have to be input.

[0071] In step S115, upon receiving the operation acceptance signal, control unit 61 may determine whether the input of the room information matches the room information recorded in server 20. If the input of the room information matches the room information recorded in server 20, control unit 61 may proceed to step S116 and generate a call signal. If the input of the room information does not match the room information recorded in server 20, control unit 61 may refuse to generate the call signal. In this case, control unit 61 may send, to collective entrance device 10, a display signal to display initial screen 200, or a display signal to display call operation screen 230.

[0072] The configurations listed below also form part of this disclosure.
