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] In some apartment buildings, it is necessary to pass through multiple gates (for example, a first gate and a second gate) to visit a resident's room. For such apartment buildings, it would be ideal to achieve both convenience and security by allowing visitors to unlock auto-lock doors without any operation by the resident.

[0005] The object of the present disclosure is to achieve both security and convenience in an intercom system for an apartment building in which a first gate and a second gate are provided on the way to a room. [Means for solving the problem]

[0006] In order to achieve the above object, the intercom system of the present disclosure comprises: a first handset that is installed near a first gate installed at the entrance of the housing complex and that allows visitors to call and talk to residents; a second handset provided near a second gate disposed between the first gate and the resident's room, for a visitor to call the resident and talk to them; a room base unit for a resident to respond to calls from the first handset and the second handset; a control unit that controls operations of the first handset, the second handset, and the room master unit; An intercom system comprising: The first slave unit and the second slave unit each have 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 control unit is capable of communicating with a first gate control device that controls locking and unlocking of the first gate and a second gate control device that controls locking and unlocking of the second gate, The control unit When at least the delivery information is input to the call operation unit of the first slave unit, a call operation is initiated to the resident's room master unit, and when an unlocking condition is satisfied for the call operation, an unlocking instruction signal is transmitted to the first gate control device; When at least the delivery information is input to the call operation unit of the second handset, an unlock instruction signal is automatically transmitted to the second gate control device.

[0007] According to the above configuration, the service provider is required to input delivery information at the first and second gates, thereby restricting the free movement of visitors and ensuring security by providing the first and second gates. Furthermore, after the service provider unlocks the first gate, the second gate is automatically unlocked by inputting the same information as entered in the information input unit of the first sub-unit into the information input unit of the second sub-unit. This reduces the time it takes for the service provider to unlock the second gate, and improves convenience for residents, as they do not have to answer the call twice. In this way, the intercom system achieves both security and convenience. [Effects of the Invention]

[0008] According to the present disclosure, it is possible to achieve both security and convenience in an intercom system for an apartment building in which a first gate and a second gate are provided on the way to a room. [Brief explanation of the drawings]

[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 first handset 10A, a second handset 10B, a server 20, a room master unit 30, a front door 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 multi-family dwelling.

[0011] The first slave unit 10A, the second slave unit 10B, the server 20, the room master unit 30, and the management room master unit 50 are connected to the control unit 60 via an intercom line L over which communication is performed according to a general-purpose protocol. The front door 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] First handset 10A is installed near first gate 91 at the entrance of the apartment building and is used by visitors to call residents. First handset 10A includes display unit 11, call unit 12, and camera 13 (an example of an imaging means).

[0013] Second handset 10B is installed near second gate 92, which is installed between first gate 91 of the apartment building and the resident's apartment, and is used by visitors to call and talk to the resident. Like first handset 10A, second handset 10B also includes display unit 11, call unit 12, and camera 13 (an example of an imaging means).

[0014] The server 20 has a function of creating a data table based on the received data. For example, the server 20 is configured to be able to receive data such as delivery information, which is information set by a service provider and is information that proves that the service provider has come to deliver a package, from an external server 70 (described later). The server 20 creates a data table based on the delivery information. Details of the delivery information will be described later.

[0015] The room master unit 30 is installed in each dwelling unit in the apartment building where the intercom system 1 is installed. The room master unit 30 includes a display unit 31, an operation unit 32, and a call unit 33. The display unit 31 can display various information and can accept user operations, and is, for example, a touch display. The display unit 31 displays images of visitors captured by the cameras 13 of the first and second sub-units 10A and 10B. The operation unit 32 is operated when answering a call from the first and second sub-units 10A and 10B 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 first and second sub-units 10A and 10B or the management room master unit 50, and includes a microphone and a speaker.

[0016] 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.

[0017] 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 cameras 13 of the first and second sub-units 10A and 10B, an operation unit 52 that is operated to call a specific room, and a call unit 53 that allows the manager to talk to residents or visitors.

[0018] The controller 60 controls the operations of the first handset 10A and the second handset 10B, the server 20, the room master unit 30, the management room master unit 50, etc. For example, the controller 60 controls the call status from the first handset 10A and the second handset 10B to the room master unit 30. The controller 60 is connected to an external server 70, a first gate control device 81, and a second gate control device 82 via a network N.

[0019] 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.

[0020] The external server 70 is, for example, a server installed at a business premises of a service provider. An example of a service provider is a delivery company. The external server 70 has a function of collecting service information set by the service provider. The service information is, for example, information for identifying a delivery item. Examples of the service information include a tracking number, a control number, and a waybill (slip) number of the delivery item. In this example, the service information is described as being a tracking number.

[0021] 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.

[0022] The first gate control device 81 is a device for controlling the locking and unlocking of a first gate 91 installed at the entrance of an apartment building to which the intercom system 1 is applied. The second gate control device 82 is a device for controlling the locking and unlocking of a second gate 92 located between the first gate 91 and the resident's apartment. The first gate control device 81 and the second gate control device 82 unlock the first gate 91 and the second gate 92, respectively, based on an unlock instruction signal transmitted from the controller 60. The unlock instruction signal transmitted to the first gate control device 81 is transmitted when an unlocking condition is satisfied in response to a call operation.

[0023] 2 is a functional block diagram of the first handset 10A, server 20, room master unit 30, and controller 60 of intercom system 1. Note that, since second handset 10B has the same configuration as first handset 10A, a description of second handset 10B will be omitted. As shown in FIG. 2, the first handset 10A includes a display unit 11, a communication unit 12, a camera 13, a central processing unit (CPU) 14 for a central entrance unit, 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 input of delivery information that proves that the service provider has come to deliver the package.

[0027] The delivery information may include at least one of service information associated with the service provider, provider information identifying the service provider, and room information for identifying the room.

[0028] The service information may be information specifying whether or not the delivery is made using a delivery service that the intercom system 1 supports.

[0029] The business information may be the name of the service business that delivers the package using the delivery service or a code that identifies the service business.

[0030] The room information may include the address of the resident who will be using the delivery service to receive delivery services.

[0031] The delivery information may further include package information associated with the package delivered by the service provider, such as a slip number assigned to the package delivered by the service provider or product tracking information assigned by an online e-commerce service.

[0032] 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.

[0033] The collective entrance unit CPU 14 performs processing to control each section of the first handset 10A and the second handset 10B. The communication IF 15 forms a bidirectional signal transmission path between the collective entrance unit CPU 14 and the intercom line L. This forms a signal transmission path between the collective entrance unit CPU 14 and the control unit 60 via the communication IF 15.

[0034] The room master unit 30 includes a master unit CPU 34, a communication IF 35, and a memory 36 in addition to a display unit 31, an operation unit 32, and a call unit 33. 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 controller 60. The memory 36 stores control information and the like for the room master unit 30. The memory 36 also stores image data captured by the cameras 13 of the first slave unit 10A and the second slave unit 10B and the camera 43 of the front door slave unit 40 and transmitted from the first slave unit 10A, the second slave unit 10B, and the front door slave unit 40.

[0035] The controller 60 includes a control unit 61 and a memory unit 62. The control unit 61 is capable of communicating with the first handset 10A and second handset 10B, the server 20, the room master unit 30, and the like, which are connected to the controller 60, and controls the transmission of signals between each unit and the connection to the network N. The memory unit 62 stores communication information, control information, and the like. 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.

[0036] The control unit 61 receives a signal including information about the room number input via the call operation unit 111 of the first handset 10A and the second handset 10B. 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 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.

[0037] Furthermore, the control unit 61 receives delivery information provided from the external server 70, stores the delivery information in the memory unit 62, and transmits the delivery information to the server 20. Note that the control unit 61 may transfer the delivery information received from the external server 70 to the server 20 without storing it in the memory unit 62.

[0038] When at least delivery information is input to the call operation unit 111 of the first sub-unit 10A, the control unit 61 starts a call operation to the resident's room master unit 30, and when the unlocking conditions for the call operation are met, it sends an unlock instruction signal to the first gate control device 81. In addition, when at least delivery information is input to the call operation unit 111 of the second sub-unit 10B, the control unit 61 automatically sends an unlock instruction signal to the second gate control device 82.

[0039] The server 20 includes a generating unit 21 and a storage unit 22. The generation unit 21 can generate a predetermined data table 22a based on delivery information 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.

[0040] 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.

[0041] 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.

[0042] (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 for explaining an example of the operation of the first handset 10A, the controller 60, the room master unit 30, and the first gate control device 81 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 first handset 10A. 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 call operation screen 220 displayed on the display unit 11. FIG. 8 is a diagram showing an example of a package information input screen 230 displayed on the display unit 11.

[0043] 5, when a service provider arrives at the entrance of the apartment complex with a delivery, an initial screen 200 is displayed on the display unit 11 of the first handset 10A. The initial screen 200 displays a "Room Call" button 201 for calling each dwelling unit in the apartment complex, 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 delivery companies. 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.

[0044] 4, it is assumed that the service provider operates the "Delivery Service" button 204 displayed on the display unit 11 of the first slave unit 10A. When the operation of the "Delivery Service" button 204 is accepted (step S101), the collective entrance unit CPU 14 transmits an operation acceptance signal to the control unit 60 (step S102). Upon receiving the operation acceptance signal, the control unit 61 of the control unit 60 transmits a display signal relating to the service selection screen 210 to the first slave unit 10A (step S103).

[0045] Having received the display signal for the service selection screen 210, the collective entrance device CPU 14 of the first slave device 10A 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 of 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.

[0046] Next, the service provider selects a predetermined display field corresponding to the company (service) to which the service provider belongs from among the plurality of 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 call operation screen 220 to the first handset 10A (step S107).

[0047] Upon receiving the display signal related to the call operation screen 220, the collective entrance device CPU 14 displays the call operation screen 220 on the display unit 11 (step S108). As shown in Fig. 7, the call operation screen 220 displays, for example, a numeric keypad button 221 for inputting the room number of each dwelling unit, a "Call" button 222, and the like. These buttons 221 and 222 included in the call operation screen 220 function as the call operation unit 111. The numeric keypad button 221 is configured to allow input of room information, and therefore also functions as the information input unit 112.

[0048] Next, the service provider inputs the room number of the room to which the delivery is to be made using the numeric keypad buttons 221 displayed on the call operation screen 220, and then operates the "Call" button 222. Upon receiving the input of the room number using the numeric keypad buttons 221 and the operation of the "Call" button 222 (step S109), the collective entrance machine CPU 14 transmits an operation acceptance signal including information about the input room number to the control unit 60 (step S110). For example, if the service provider inputs the room number "101" on the call operation screen 220 and then operates the "Call" button 222, the collective entrance machine CPU 14 transmits an operation acceptance signal including information corresponding to the room number "101" to the control unit 60.

[0049] 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 S111). The control unit 61 then transmits the call signal to the identified room master unit 30 (step S112). For example, the control unit 61 identifies the room master unit 30 in room 101 based on the information about the room number "101" included in the received operation acceptance signal, and generates a call signal for calling the room master unit 30. The control unit 61 then transmits the call signal to the identified room master unit 30 in room 101.

[0050] 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 that a visitor is calling from the common entrance (step S113). 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.

[0051] The unlocking conditions, which are the conditions for unlocking the first gate 91, include a first unlocking condition and a second unlocking condition. When either the first unlocking condition or the second unlocking condition is satisfied, the control unit 61 determines that the unlocking conditions are satisfied.

[0052] The first unlocking condition is that the resident responds to the call and agrees to allow the visitor to pass 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 first gate 91 and second gate 92 and performs delivery to a door because the resident is absent or does not answer, so a description of the operation of first handset 10A and control unit 60 under the first unlocking condition will be omitted.

[0053] The second unlocking condition is that the resident does not respond to the call operation, and the controller 60 determines that the delivery information recorded in the server 20 matches the delivery information entered by the visitor. In this embodiment, the operation of the first slave unit 10A and the controller 60 when the second unlocking condition is met will be described.

[0054] The control unit 61 determines whether a certain time has elapsed since the room master unit 30 started to output a ring tone (step S114). 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 set individually 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 certain time is not limited to the start of the output of a ring tone 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 S114 that a certain time has not elapsed since the room master unit 30 started to output a ring tone (NO in step S114), the control unit 61 repeats the operation of step S114 until the certain time has elapsed. If it is determined in step S114 that a certain time has elapsed since the room master unit 30 started to output a ring tone (YES in step S114), the control unit 61 transmits a display signal for the package information input screen 230 to the first slave unit 10A (step S115).

[0056] Upon receiving the display signal related to the package information input screen 230, the collective entrance device CPU 14 displays the package information input screen 230 on the display unit 11 (step S116). As shown in Fig. 8, the package information input screen 230 displays, for example, a numeric keypad button 231 for inputting a slip number, a "Decide" button 232, an "End" button 233, and the like. These buttons 231 to 233 included in the package information input screen 230 function as the information input unit 112.

[0057] Next, the service provider uses the numeric keypad buttons 231 on the package information input screen 230 to input the slip number and the like as package information, and then operates the "OK" button 232. Upon receiving the input of package information and the operation of the "OK" button 232 (step S117), 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 S118). For example, if the service provider inputs the slip number "101-***-***" in step S117, the collective entrance machine CPU 14 transmits an operation acceptance signal including "101-***-***" to the control unit 60.

[0058] Next, upon receiving the operation acceptance signal, control unit 61 verifies whether the delivery information entered by the visitor on first sub-unit 10A matches the delivery information contained in data table 22a stored in memory unit 22 of server 20 (step S119). For example, if the visitor enters "Company: A" (step S104), "Room number: 101" (step S109), and "Invoice number: 101-***-***" (step S117), data corresponding to "Company: A," "Room number: 101," and "Invoice number: 101-***-***" are stored in data table 22a in the example of FIG. 3, and therefore control unit 61 determines that the respective delivery information matches.

[0059] Next, if the delivery information included in the operation acceptance signal matches the delivery information included in the data table 22a (YES in step S119), the control unit 61 determines that the authentication has been successful and that the second unlocking condition has been met, and transmits an unlock instruction signal to the first gate control device 81 (step S120). Then, the first gate control device 81, which has received the unlock instruction signal, unlocks the first gate 91 (step S121). This allows the service provider to enter the first gate 91. Note that if the service numbers match, the control unit 61 may transmit an authentication success signal to the first handset 10A. At this time, the first handset 10A, which has received the authentication success signal, may display a notification screen on the display unit 11, for example, stating "The gate will be unlocked," as notification information that the authentication has been successful.

[0060] On the other hand, if the delivery information included in the operation acceptance signal does not match the service number included in the data table 22a (NO in step S119), the control unit 61 determines that the authentication has failed and terminates the process without sending an unlock instruction signal to the first gate control device 81 (step S122). Therefore, the first gate 91 is not unlocked and remains locked. Note that if the delivery information does not match, the control unit 61 may send an authentication failure signal to the first sub-unit 10A. In this case, the first sub-unit 10A that has received the authentication failure signal may display a notification screen on the display unit 11 notifying the fact that the authentication has failed, such as "Unlocking not possible. Please try again by clicking the 'Delivery Service' button."

[0061] When the second unlocking condition is satisfied, the control unit 61 may send a notification to the resident. The control unit 61 may send the notification to the room master unit 30, or may send the notification to a mobile terminal or the like owned by the resident. When sending the notification to 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. When sending the notification to a mobile terminal or the like owned by the resident, the control unit 61 may cause a screen indicating that the service provider has visited to be displayed on the screen of the mobile terminal.

[0062] Next, the operations of the second handset 10B, the controller 60, and the second gate control device 82 will be described with reference to Fig. 9. Fig. 9 is a flowchart for explaining an example of the operations of the second handset 10B, the controller 60, and the second gate control device 82 in the intercom system 1. Note that detailed explanations of the operations common to the first handset 10A and the second handset 10B will be omitted.

[0063] The display unit 11 of the second handset 10B also displays an initial screen 200, similar to the first handset 10A illustrated in Fig. 5. The initial screen 200 displays a "Room Call" button 201, a "Management Office Call" button 202, a "Resident Service" button 203, and a "Delivery Service" button 204.

[0064] Steps S123 to S129 correspond to steps S101 to S107. As illustrated in Fig. 9, it is assumed that the service provider operates the "Delivery Service" button 204 displayed on the display unit 11 of the second handset 10B. When the operation of the "Delivery Service" button 204 is accepted (step S123), the collective entrance unit CPU 14 transmits an operation acceptance signal to the control unit 60 (step S124). Upon receiving the operation acceptance signal, the control unit 61 of the control unit 60 transmits a display signal relating to the service selection screen 210 to the second handset 10B (step S125).

[0065] Upon receiving the display signal for the service selection screen 210, the collective entrance device CPU 14 of the second handset 10B displays the service selection screen 210 on the display unit 11 (step S126). The service selection screen 210 displayed on the display unit 11 of the second handset 10B is the same as the service selection screen 210 displayed on the display unit 11 of the first handset 10A, as shown in FIG.

[0066] Next, the service provider selects a predetermined display field corresponding to the company (service) to which the service provider belongs from among the plurality of display fields 211A-211E displayed on the service selection screen 210, and then operates the "End" button 212. When each of the display fields 211A-211E receives an operation by the service provider on one of the display fields 211A-211E (step S127), the central entrance device CPU 14 transmits an operation reception signal including information on the selected display field to the control device 60 (step S128). Upon receiving the operation reception signal, the control unit 61 transmits a display signal related to the room number input screen 240 to the second handset 10B (step S129).

[0067] 10 is a diagram showing an example of a room number input screen 240 displayed on the display unit 11. Upon receiving a display signal related to the room number input screen 240, the collective entrance device CPU 14 causes the display unit 11 to display the room number input screen 240 (step S130). Unlike the call operation screen 220 displayed on the display unit 11 of the first handset 10A, the room number input screen 240 does not display the "Call" button 222, but instead displays a "Confirm" button 242. Accordingly, the displayed text has also been changed from "Please enter the room number and press call" to "Please enter the room number."

[0068] Next, the service provider inputs the room number of the room to which the delivery is to be made using numeric keypad buttons 221 displayed on room number input screen 240, and then operates "OK" button 242. Upon receiving the input of the room number using numeric keypad buttons 221 and the operation of "OK" button 242 (step S131), collective entrance device CPU 14 transmits an operation acceptance signal including information about the input room number to control device 60 (step S132). Upon receiving the operation acceptance signal, control unit 61 transmits a display signal related to package information input screen 230 to second sub-device 10B (step S133).

[0069] Next, upon receiving the display signal for the room number input screen 240, the collective entrance device CPU 14 displays the package information input screen 230 on the display unit 11 (step S134). The package information input screen 230 displayed on the display unit 11 of the second sub-device 10B is the same as the package information input screen 230 displayed on the display unit 11 of the first sub-device 10A, as shown in FIG. 7. The service provider inputs package information using the numeric keypad buttons 231 on the package information input screen 230, and then operates the "OK" button 232. Upon accepting the input of package information and the operation of the "OK" button 232 (step S135), the collective entrance device CPU 14 transmits an operation acceptance signal including the input package information to the control device 60 as an unlock request (step S136).

[0070] Next, the control unit 61, having received the operation acceptance signal, checks whether the delivery information entered by the visitor on the second sub-unit 10B matches the delivery information contained in the data table 22a stored in the memory unit 22 of the server 20, as in step S119 (step S137).

[0071] Next, if the delivery information included in the operation acceptance signal matches the delivery information included in the data table 22a (YES in step S137), the control unit 61 determines that the authentication is successful and transmits an unlock instruction signal to the second gate control device 82 (step S138). Then, the second gate control device 82, which has received the unlock instruction signal, unlocks the second gate 92 (step S139). This allows the service provider to enter the second gate 92. Note that if the service numbers match, the control unit 61 may transmit an authentication success signal to the second handset 10B. At this time, the second handset 10B, which has received the authentication success signal, may display a notification screen on the display unit 11, for example, stating "The gate will be unlocked," as notification information that the authentication has been successful.

[0072] On the other hand, if the delivery information included in the operation acceptance signal does not match the service number included in the data table 22a (NO in step S137), the control unit 61 determines that the authentication has failed and terminates the process without sending an unlock instruction signal to the second gate control device 82 (step S140). Therefore, the second gate 92 is not unlocked and remains locked. Note that if the delivery information does not match, the control unit 61 may send an authentication failure signal to the second sub-unit 10B. In this case, the second sub-unit 10B that has received the authentication failure signal may display a notification screen on the display unit 11, such as "Unlocked. Please try again by clicking the 'Delivery Service' button.", as notification information that the authentication has failed.

[0073] Note that the control unit 61 sends a notification to the resident when the unlocking conditions are met at the first gate 91, but does not send a notification when sending an unlocking instruction signal to the second gate control device 82. This prevents the resident from receiving duplicate notifications for a single delivery.

[0074] According to the intercom system 1 configured as described above, the service provider is required to input delivery information at the first gate 91 and the second gate 92, thereby restricting the free movement of visitors and ensuring the security provided by the provision of the first gate 91 and the second gate 92. Furthermore, after the service provider unlocks the first gate 91, the second gate 92 is automatically unlocked by inputting the same information as that input in the information input unit 112 of the first handset 10A into the information input unit 112 of the second handset 10B. This reduces the time required for the service provider to unlock the second gate 92, and improves convenience for residents, as they do not have to answer the call twice. In this way, the intercom system 1 can achieve both security and convenience.

[0075] According to the intercom system 1 configured as described above, the delivery information includes at least one of service information, business information, room information, and package information, making it possible to perform verification based on multiple pieces of information, thereby improving the security of the intercom system 1.

[0076] According to the intercom system 1 configured as described above, the unlocking conditions include a first unlocking condition and a second unlocking condition. As with the first unlocking condition, the resident directly allows the visitor to pass through. As with the second unlocking condition, the service provider can allow the visitor to pass through the first gate 91 and the second gate 92 without the resident having to respond to the visitor by comparing delivery information recorded in advance on the server with delivery information entered by the visitor. This allows the resident to enjoy the service while ensuring security, even if the resident is not present when the service provider visits.

[0077] According to the intercom system 1 configured as described above, the delivery information further includes package information, and under the second unlocking condition, the delivery information recorded on the server is compared to the delivery information entered by the visitor to see if they match. By also comparing the package information under the second unlocking condition, the security of the intercom system 1 is improved.

[0078] When the unlocking conditions are met, the control unit 61 sends a notification to the resident, but does not send a notification when sending an unlocking instruction signal to the second gate control device 82. The resident receives a notification when the service provider passes through the first gate 91, but does not receive a notification when the service provider passes through the second gate 92, thereby preventing the resident from receiving two notifications for one delivery. This reduces the inconvenience of the intercom system 1 for the resident.
