Description

[Technical Field]

[0001] The present invention relates to an intercom system and a control method in an intercom system. [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. (for example, Patent Document 1 and Patent Document 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] The technologies disclosed in Patent Documents 1 and 2 allow the auto-lock door to be unlocked by a visitor alone, without any operation by the resident, so there is room for improvement in terms of security measures.

[0005] Therefore, an object of the present invention is to provide an intercom system and a control method for the intercom system that can improve security while suppressing the complexity of data processing. [Means for solving the problem]

[0006] In order to achieve the above object, the intercom system of the present invention comprises: An intercom system comprising: 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, 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 service information associated with a service provider, and an imaging unit for imaging the visitor; The control unit a first imaging mode in which the imaging unit starts capturing a first captured image based on an input operation by the visitor to the information input unit, and a second imaging mode in which the imaging unit starts capturing a second captured image based on a call operation by the visitor to the call operation unit, When the second imaging mode is executed after the first imaging mode, the second captured image is transmitted to the room master unit instead of the first captured image. It is structured as follows.

[0007] According to the above configuration, when a service provider such as a delivery company visits a residence, the imaging unit starts capturing an image of the visitor (capturing a first captured image) at the timing when the delivery company performs an input operation on the information input unit. This allows imaging of the visitor to begin earlier than before, allowing the first captured image to be viewed later as needed, thereby improving security. On the other hand, if a call operation is performed on the call operation unit after an input operation on the information input unit, the second captured image captured at the timing of the call operation is transmitted to the room master unit instead of the first captured image. This allows only the second captured image to be viewed on the room master unit when the call operation is performed and the resident responds, thereby avoiding cumbersome data processing on the room master unit and an increase in the amount of stored data.

[0008] In order to achieve the above object, a control method for an intercom system according to the present invention comprises: A control method for an intercom system including a handset for a visitor to call a resident and talk to the visitor, a room base unit for the resident to respond to the call from the handset, and a control unit that controls the handset and the room base unit to be able to communicate with each other, receiving an input operation to an information input unit provided in the slave device for inputting service information associated with a service provider; receiving a call operation on a call operation unit provided in the handset to execute a call operation from the handset to the room master unit; executing a first imaging mode in which an imaging unit provided in the slave device starts capturing a first captured image based on the input operation on the information input unit; executing a second imaging mode in which capturing of a second captured image by the imaging unit is started based on the call operation on the call operation unit; When the second imaging mode is executed after the first imaging mode, transmitting the second captured image to the room master unit instead of the first captured image; Includes:

[0009] According to the above configuration, when a service provider such as a delivery company visits a residence, the imaging unit starts imaging the visitor (capturing the first captured image) at the timing when the delivery company performs an input operation on the information input unit, so imaging of the visitor starts earlier than before, and the first captured image can be checked later as needed, thereby improving security. Furthermore, if a call operation is performed on the call operation unit after an input operation on the information input unit, the second captured image captured at the timing of the call operation is sent to the room master unit instead of the first captured image. Therefore, when the call operation is performed and the resident responds, only the second captured image can be checked on the room master unit side, avoiding complication of data processing on the room master unit side and an increase in the amount of stored data. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide an intercom system and a control method for the intercom system that can improve security while suppressing the complexity of data processing. [Brief explanation of the drawings]

[0012] (Intercom system configuration) Hereinafter, an intercom system according to an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a configuration diagram showing an intercom system 1 according to an embodiment. As shown in Fig. 1, the intercom system 1 includes a collective entrance unit 10 (an example of a slave unit), a control unit 20, a room master unit 30, a entrance slave unit 40, a server 50, a mobile terminal 70, and a door control device 80. The intercom system 1 is a system that is applied to, for example, an apartment building or other collective housing complex.

[0013] The collective entrance unit 10 and the room master unit 30 are connected to the control unit 20 via an intercom line L, over which communication is performed 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.

[0014] The collective entrance device 10 is installed at the collective entrance (entrance), which is a common space of the apartment complex. The collective entrance device 10 comprises a display unit 11, a call unit 12, and a camera 13 (an example of an imaging unit). The display unit 11 is capable of displaying various information and accepting operations from visitors, and may be a touch display, for example. The call unit 12 is used by visitors to communicate with the room master unit 30, and includes a microphone and speaker. The camera 13 is capable of capturing images of the visitor, for example.

[0015] The control unit 20 controls the operation of the collective entrance unit 10, the room main unit 30, etc. For example, the control unit 20 controls the call status from the collective entrance unit 10 to the room main unit 30. The control unit 20 is also connected to the server 50, the mobile terminal 70, and the door control device 80 via the network N.

[0016] The controller 20 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 20 may be configured with multiple CPU cores. The controller 20 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 20 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 20 may also be configured with a combination of at least one microcontroller and an integrated circuit.

[0017] The room master unit 30 is installed in each dwelling unit of the apartment building where the intercom system 1 is installed. The room master unit 30 comprises a display unit 31, 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 answering a call from the collective entrance unit 10. The operation unit 32 is composed of operation buttons, for example, 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, and includes a microphone and speaker.

[0018] 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 a visitor uses to call the resident, a communication unit 42 that the visitor uses 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.

[0019] The server 50 is, for example, a server installed at a business establishment of a service provider. An example of a service provider is a delivery company. The server 50 has a function of collecting service information set by the service provider and creating a data table. 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 following description will be given assuming that the service information is a tracking number. Details of the data table will be given later.

[0020] When a delivery company receives a delivery addressed to a resident from a third party (sender), it determines a tracking number as service information. The delivery company notifies the sender of the tracking number it has set and transmits the tracking number and delivery address to server 50. The sender or delivery company also notifies the resident, who is the destination (consignee), of the delivery information, including the tracking number. The resident, who has received the delivery information, sets the desired delivery method (direct delivery, delivery to a designated location, etc.), and notifies the sender or delivery company of the information regarding the desired delivery method. The delivery company, having received the information regarding the delivery method from the resident directly or via the sender, transmits the information regarding the delivery method to server 50.

[0021] The mobile terminal 70 is a terminal carried by the delivery person. Examples of the mobile terminal 70 include a mobile phone, smartphone, tablet, laptop, personal computer, etc. In particular, the mobile terminal 70 is preferably a portable communication terminal device that can be carried around, such as a mobile phone, smartphone, tablet, or laptop. The delivery person can use the mobile terminal 70 to check delivery information for the package that they are responsible for delivering. The delivery information for each package includes the tracking number of the package, the delivery address, the delivery method, the desired delivery time, etc. Delivery methods include, for example, directly handing the package to the recipient, as well as "drop-off delivery," in which the delivery is completed by leaving the package at their front door, and "box delivery," in which the delivery is completed by placing the package in a designated delivery box.

[0022] Door control device 80 is a device for controlling the locking and unlocking of door 90 installed at the entrance of an apartment building. For example, when multiple entrance device 10 or mobile terminal 70 is operated, an unlock request signal requesting unlocking of door 90 is sent from multiple entrance device 10 or mobile terminal 70 to control device 20. Door control device 80 unlocks door 90 based on the unlock instruction signal sent from control device 20.

[0023] FIG. 2 is a functional block diagram of the collective entrance unit 10, the control unit 20, the room master unit 30, and the server 50 of the intercom system 1. As shown in FIG.

[0024] The collective entrance device 10 includes a display unit 11, a communication unit 12, and a camera 13, as well as a collective entrance device CPU (Central Processing Unit) 14 and a communication interface (IF) 15.

[0025] The display unit 11 is configured to be able to display a call operation unit 111 and a service selection unit 112 (an example of an information input unit). That is, the display unit 11 also functions as an input unit for accepting various operations from the user.

[0026] The call operation unit 111 is an operation unit operated by a visitor when calling a resident. The call operation unit 111 is configured, for example, with a numeric keypad, call buttons, etc. displayed on the display unit 11. The service selection unit 112 is an input unit for inputting service information associated with a service provider. The input operations for the service selection unit 112 include a first input operation for starting the execution of a predetermined service, a second input operation for inputting attributes of a provider of the predetermined service after the first input operation, and a third input operation for inputting an identification number related to the predetermined service after the second input operation.

[0027] The first input operation includes, for example, an operation by a service provider, such as a delivery company, to start providing delivery services. The second input operation includes, for example, an input operation by the service provider to select the type of service or attributes of the service provider. Specifically, a list of registered delivery companies is displayed in the service selection unit 112, and if the visitor is a delivery company, the visitor selects which delivery company the visitor belongs to in the service selection unit 112. The third input operation includes, for example, an input operation by the service provider to specify the content of the service. Specifically, the delivery company inputs the tracking number and slip number of the delivery item, the room number of the delivery destination, etc. into the service selection unit 112.

[0028] 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 20 via the communication IF 15.

[0029] The collective entrance device CPU 14 also has a function of transmitting an unlock request signal to the control device 20 based on the reception of an operation of the service selection unit 112 by the delivery company.

[0030] The control unit 20 includes a control unit 21 and a memory unit 22 (an example of a first memory unit). The control unit 21 transmits and receives signals to and from the collective entrance unit 10, the room master unit 30, and each unit of the network N, which are connected to the control unit 20. The memory unit 22 stores communication information, control information, and the like. In this example, the memory unit 22 stores a call table 22a in which the room number of each dwelling unit in the apartment building is associated with a room master unit ID that can identify the room master unit 30 of each dwelling unit. The memory unit 22 also stores images of visitors captured by the camera 13 of the collective entrance unit 10.

[0031] The control unit 21 can execute a first imaging mode in which the camera 13 starts capturing a first captured image based on an input operation by the visitor to the service selection unit 112 of the collective entrance device 10, and a second imaging mode in which the camera 13 starts capturing a second captured image based on a call operation by the visitor to the service selection unit 112. The captured first and second captured images are stored in the storage unit 22. The control unit 21 also erases the first captured image of the stored first and second captured images from the storage unit 22 after a predetermined period of time (for example, two weeks from the date of capture) has elapsed.

[0032] The control unit 21 also receives a signal including information about the room number inputted by the call operation unit 111 of the collective entrance unit 10. The control unit 21 refers to the call table 22a and identifies the room master unit 30 of the dwelling unit that is associated with the room number inputted by the call operation unit 111. The control unit 21 transmits a call signal to the identified room master unit 30.

[0033] Furthermore, the control unit 21 receives an unlock request signal requesting unlocking of the common entrance door 90 from the common entrance device 10 and the mobile terminal 70. The control unit 21 has an authentication unit 21a and an unlock instruction unit 21b.

[0034] The authentication unit 21a authenticates the information included in the unlock request signal transmitted from the collective entrance device 10 and the information in the data table 51a stored in the memory unit 51 of the server 50. The authentication unit 21a also authenticates the information included in the unlock request signal transmitted from the mobile terminal 70 and the information in the data table 51a stored in the memory unit 51 of the server 50.

[0035] Based on the result of authentication by authentication unit 21a, unlocking instruction unit 21b transmits an unlocking instruction signal to door control device 80. For example, when information included in the unlocking request signal from collective entrance device 10 matches information in data table 51a of server 50, or when information included in the unlocking request signal from mobile terminal 70 matches information in data table 51a of server 50, unlocking instruction unit 21b transmits the unlocking instruction signal to door control device 80. In this embodiment, the control unit 21 of the control device 20 includes the authentication unit 21a and the unlock instruction unit 21b, but the server 50 may include functions equivalent to the authentication unit 21a and the unlock instruction unit 21b.

[0036] The room master unit 30 includes a master unit CPU 34, a communication IF 35, and a memory 36 (an example of a second memory) 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 establishes a bidirectional signal transmission path between the master unit CPU 34 and the intercom line L. This establishes a signal transmission path between the master unit CPU 34 and the control unit 20. 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 camera 13 of the collective entrance unit 10 and transmitted from the control unit 20. For example, the memory 36 stores the first and second captured images, or only the second captured image, captured by the camera 13 of the collective entrance unit 10. The memory 36 also stores image data captured by the camera 43 of the entrance slave unit 40.

[0037] The server 50 includes a storage unit 51 and a transmission unit 52. The storage unit 51 stores a data table 51a generated based on information received from the service provider, including the tracking number and delivery destination of the delivery. The transmission unit 52 transmits to the control device 20 the information in the data table 51a used by the authentication unit 21a of the control device 20 when performing authentication.

[0038] FIG. 3 is a diagram showing an example of a data table 51a stored in the server 50. As shown in FIG. 3, the data table 51a stores the tracking number of a delivery item received by the server 50, the delivery address of the delivery item, and the delivery method, all associated with one another. The delivery method is a predetermined delivery method set by the user of the delivery destination. For example, whether or not drop-off is possible is set. In the data table 51a shown in FIG. 3, for example, the tracking number of one delivery item "101-***-***," the delivery address of the delivery item "*********, Meguro-ku, Tokyo," and the delivery method of the delivery item "drop-off possible" are stored in association with one another. In addition, the tracking number of another delivery item "151-***-***," the delivery address of the delivery item "*********, Setagaya-ku, Tokyo," and the delivery method of the delivery item "drop-off not possible" are stored in association with one another.

[0039] (Intercom System 1 Operation) Next, the operation of the intercom system 1 when a visitor, a delivery person, visits the apartment complex to deliver a package addressed to a resident of the apartment complex will be described with reference to FIGS. 4 to 10. FIG. 4 is a flowchart for explaining an example of the operation of the intercom system 1. FIG. 5 is a diagram showing an example of a delivery information screen 700 displayed on the mobile terminal 70. FIG. 6 is a diagram showing an example of an initial screen 200 displayed on the display unit 11 of the collective entrance unit 10. FIG. 7 is a diagram showing an example of a service selection screen 210 displayed on the display unit 11 of the collective entrance unit 10. FIG. 8 is a diagram showing an example of a call operation screen 220 displayed on the display unit 11. FIG. 9 is a diagram showing an example of a service information input screen 230 displayed on the display unit 11 of the collective entrance unit 10. FIG. 10 is a diagram showing an example of a device operation request screen 240 displayed on the display unit 11 of the collective entrance unit 10. FIG. 11 is a diagram showing an example of an unlocking operation screen 710 displayed on the mobile terminal 70.

[0040] In FIG. 4, the delivery company causes the mobile terminal 70 to display delivery information regarding the target delivery item on the display screen (Step S1).

[0041] As shown in FIG. 5, the mobile terminal 70 displays a delivery information screen 700 that displays delivery information related to the delivery item. The delivery information screen 700 includes information transmitted from the server 50 based on the data table 51a stored in the server 50. For example, the delivery information screen 700 displays a number display field 701 that displays the tracking number of the delivery item, an address display field 702 that displays the delivery address, a delivery display field 703 that displays the predetermined delivery method set by the user of the delivery address, and a confirmation button 704. The delivery company checks the display fields 701 to 703 on the delivery information screen 700 to understand the delivery address and delivery method of the delivery item.

[0042] Here, suppose that a delivery person checks delivery information screen 700 on mobile terminal 70 and then arrives with a delivery at the entrance of an apartment building whose delivery address is displayed on delivery information screen 700. At this time, an initial screen 200 such as that shown in FIG. 6 is displayed on display unit 11 of collective entrance device 10 installed at the entrance of the apartment building. 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 management office, a "Resident Service" button 203 for executing various services for residents, and a "Delivery Service" button 204 for starting execution of services for service providers such as delivery people. The delivery person performs a touch operation (an example of a first input operation) on "Delivery Service" button 204 displayed on display unit 11 of collective entrance device 10.

[0043] 4, when a touch operation (first input operation) of the "Delivery Service" button 204 on the initial screen 200 is received (step S2), the collective entrance device CPU 14 of the collective entrance device 10 starts capturing a first captured image (capturing in the first imaging mode) with the camera 13 (step S3). The first captured image captured by the camera 13 is an image of the surroundings of the collective entrance device 10, with the delivery person operating the collective entrance device 10 at the center.

[0044] Next, the collective entrance device CPU 14 displays the service selection screen 210 on the display unit 11 (step S4). As shown in Fig. 7, the service selection screen 210 displays, for example, display fields 211A-211E for the company names or service names of the service providers, and an "End" button 212. The delivery person selects the display field corresponding to the company (service) to which the delivery person 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 delivery person selects, by touch operation, display field 211A from display fields 211A-211E, which are the service selection unit 112.

[0045] 4, when an operation by the delivery company on any one of display fields 211A to 211E on service selection screen 210 is accepted, collective entrance machine CPU 14 displays call operation screen 220 on display unit 11 (step S5). As shown in Fig. 8, call operation screen 220 displays, for example, numeric keypad buttons 221 for inputting the room number of each dwelling unit, a "call" button 222, etc.

[0046] Next, the delivery person inputs the room number of the room to which the delivery item is to be delivered 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 S6), the collective entrance machine CPU 14 transmits an operation acceptance signal including information on the input room number to the control unit 20 (step S7). For example, if the delivery person inputs the room number "201" 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 "201" to the control unit 20.

[0047] Upon receiving the operation acceptance signal from the collective entrance unit 10, the control unit 21 of the control unit 20 determines whether a response action to the call operation is required (step S8). Specifically, the control unit 21 determines whether a response action is required from the room master unit 30 corresponding to the room number included in the operation acceptance signal, based on the call table 22a stored in the memory unit 22. The call table 22a contains, for example, information regarding whether a response action to a call operation is required for each room in an apartment building. The necessity of a response action can be set by the resident of each room using each room master unit 30. For example, if the room associated with the service number entered on the service information input screen 230 is preset so that the room master unit 30 does not respond to a call from the collective entrance unit 10, it is determined that a call is not required.

[0048] If it is determined in step S8 that a response action to the call is required (Yes in step S8), the control unit 21 transmits a signal to the collective entrance unit 10 indicating that a response action to the call operation from the visitor is required. Upon receiving this signal, the collective entrance unit CPU 14 of the collective entrance unit 10 transmits to the room master unit 30 a call signal indicating that a call operation has been performed by the visitor, and an image of the visitor captured by the camera 13 from the time the call operation was accepted in step S6 (second captured image) (step S9). In other words, the second captured image is an image captured in the second imaging mode in which imaging is started by the camera 13 based on the visitor's call operation on the call operation screen 220.

[0049] Next, the room master unit 30 receives the call signal and the second captured image from the collective entrance unit 10, and issues a call sound to indicate that a visitor is calling from the collective entrance, and stores the second captured image in the memory unit 36 ​​(step S10).

[0050] On the other hand, if it is determined in step S8 that a response action to the call is not required (No in step S8), the control unit 21 instructs the collective entrance device 10 to display the service information input screen 230 on the display unit 11. Upon receiving this instruction, the collective entrance device CPU 14 of the collective entrance device 10 displays the service information input screen 230 on the display unit 11 (step S11). As shown in FIG. 9, the service information input screen 230 displays, for example, a "numeric keypad" button 231, a "decide" button 232, an "end" button 233, and the like for inputting service information. The delivery company uses the "numeric keypad" button 231 on the service information input screen 230 to input, for example, the tracking number of the delivery item as service information, and then operates the "decide" button 232. Upon receiving the input of the service information (step S12), the collective entrance device CPU 14 transmits the received service information to the control device 20 (step S13). For example, if a delivery company enters the tracking number "101-***-***" as the service number on the service information input screen 230, the collective entrance unit 10 will send an unlock request signal including "101-***-***" to the control unit 20.

[0051] Next, the collective entrance machine CPU 14 causes the display unit 11 to display a device operation request screen 240 (step S14). As shown in FIG. 10, the device operation request screen 240 displays a message 241 guiding the delivery person to perform an unlocking operation using the mobile terminal 70. For example, the device operation request screen 240 displays a message 241 such as "Please operate your unlocking device." It is also possible to not display the device operation request screen 240 in step S14, but instead display a device operation request message such as "Alternatively, please operate your unlocking device" in addition to "Please enter the service number" on the service information input screen 230 (see FIG. 9) displayed in step S11, thereby notifying the delivery person that an unlocking request operation can also be performed using the mobile terminal 70.

[0052] Next, the delivery person confirms the message 241 displayed on the device operation request screen 240 and touches the confirmation button 704 on the delivery information screen 700 (see FIG. 5) displayed on the mobile terminal 70 in step S1.

[0053] Returning to Fig. 4, the mobile terminal 70 accepts the delivery company's touch operation of the confirmation button 704, and displays an unlocking operation screen 710 on the display screen of the mobile terminal 70 (step S15). As shown in Fig. 11, the unlocking operation screen 710 displays an unlocking request button 711 for requesting the unlocking of the entrance door 90 of the apartment building. It is assumed that the delivery company touches the unlocking request button 711 on the unlocking operation screen 710 displayed on the mobile terminal 70.

[0054] Returning to FIG. 4, when the delivery person operates unlock request button 711, mobile terminal 70 accepts the unlock request operation (step S16) and transmits an unlock request signal to controller 20 (step S17).

[0055] Next, when the control unit 21 of the control device 20 receives an unlocking request signal from the mobile terminal 70, the control unit 21 verifies, via the authentication unit 21a, whether or not the information included in the unlocking request signal (e.g., a tracking number) matches the information in the data table 51a stored in the server 50 (step S18). For example, when an unlocking request signal including the service number "101-***-***" input as the tracking number is received, the control unit 21 communicates with the server 50 and verifies whether or not the service number "101-***-***" is included in the data table 51a stored in the storage unit 51. Furthermore, when the control unit 21 receives service information from the multiple entrance device 10 in step S13, the control unit 21 verifies whether or not the service information (e.g., a tracking number) matches the information in the data table 51a stored in the server 50.

[0056] In step S18, if the information contained in the unlocking request signal received from the mobile terminal 70 and the service information received from the collective entrance device 10 match the information in the data table 51a (YES in step S18), the control unit 21 determines that the authentication is successful, generates an unlocking instruction signal to unlock the door 90 by the unlocking instruction unit 21b (step S19), and transmits the unlocking instruction signal generated by the unlocking instruction unit 21b to the door control device 80 (step S20).

[0057] Upon receiving the unlock instruction signal, door control device 80 unlocks entrance door 90 of the apartment building (step S21), allowing the delivery person to enter the apartment building through door 90 and perform delivery work.

[0058] Furthermore, in step S18, if the information included in the unlock request signal matches the information in the data table 51a (YES in step S18), the control unit 21 transmits an entry notification signal to notify the visitor of their entry into the apartment building (step S22). Furthermore, the control unit 21 instructs the collective entrance unit 10 to transmit the first and second captured images captured by the camera 13 of the collective entrance unit 10 to the room master unit 30 (step S23). Upon receiving this instruction, the collective entrance unit CPU 14 of the collective entrance unit 10 transmits to the room master unit 30 data of the first captured image captured by the camera 13 from the time when the touch operation of the "Delivery Service" button 204 on the initial screen 200 was accepted in step S2, and data of the second captured image captured by the camera 13 from the time when the call operation on the call operation screen 220 was accepted in step S6 (step S24). The first captured image and the second captured image may be a continuous series of image data.

[0059] Upon receiving the entry notification signal from the control unit 21, the room master unit 30 displays the entry notification on the display unit 31 and stores the first captured image and the second captured image received from the collective entrance unit 10 in the memory unit 36 ​​(step S25).

[0060] On the other hand, in step S18, if the information contained in the unlocking request signal does not match the information in the data table 51a (NO in step S18), the control unit 20 determines that the authentication has failed, generates an authentication failure signal, and transmits the generated authentication failure signal to the mobile terminal 70 (step S26).

[0061] Upon receiving the authentication failure signal, the mobile terminal 70 displays an authentication failure notification screen indicating that the unlocking request made by operating the unlocking request button 711 has not been accepted (step S27).

[0062] As described above, the intercom system 1 of the embodiment can execute a first imaging mode in which the camera 13 starts capturing a first captured image based on an input operation by the visitor via the service selection unit 112, and a second imaging mode in which the camera 13 starts capturing a second captured image based on a call operation by the visitor via the call operation unit 111. If the second imaging mode is executed after the first imaging mode, a second captured image captured in the second imaging mode is transmitted to the room master unit 30 instead of the first captured image captured in the first imaging mode. With this configuration, for example, when a service provider such as a delivery company visits an apartment building, the camera 13 starts capturing a first captured image of the visitor at the timing when the delivery company performs an input operation via the service selection unit 112. As a result, imaging of the visitor is started earlier than in the past, in which imaging is started when the visitor presses the call button, for example. Therefore, the captured first captured image can be checked later as needed, improving security. Furthermore, if a call operation is performed on the call operation unit 111 after an input operation on the service selection unit 112, the second captured image captured at the timing of the call operation is transmitted to the room master unit 30 instead of the first captured image. As a result, when a call operation is performed and the resident responds to the call, only the second captured image can be confirmed on the room master unit 30 side, thereby avoiding complication of processing captured image data on the room master unit 30 side and an increase in the amount of stored data.

[0063] Furthermore, in the intercom system 1, even if the second imaging mode is executed after the first imaging mode, if the room master unit 30 is set not to respond to a call operation, the first imaging image captured in the first imaging mode is transmitted to the room master unit 30 in addition to or instead of the second imaging image captured in the second imaging mode. According to this configuration, if the resident has set not to respond to a call operation, the first imaging image captured in the first imaging mode is also transmitted to the room master unit 30, so that the first imaging image captured at an earlier timing than before can be confirmed on the room master unit 30 side, further improving security.

[0064] Furthermore, when control unit 21 of intercom system 1 receives an unlock request signal from mobile terminal 70 requesting unlocking of door 90 and receives service information from collective entrance unit 10, it authenticates whether the service information (e.g., a tracking number, etc.) included in the unlock request signal and the service information received from collective entrance unit 10 match the information in data table 51a stored in server 50, and if it authenticates that this information matches (authentication is successful), it sends an unlock instruction signal to door control device 80 instructing it to unlock door 90, and sends an entry notification signal notifying the entry of a visitor into the apartment building, together with the first and second captured images, to room master unit 30. With this configuration, when authentication of the service information (e.g., a delivery slip number, etc.) is successful and the door is automatically unlocked, the first captured image can be viewed on the room master unit 30 along with the entry notification, thereby improving convenience for residents and visitors while maintaining security.

[0065] Furthermore, the control unit 21 is configured to erase the first captured image stored in the storage unit 22 from the storage unit 22 after a predetermined period has elapsed since the first captured image was stored. According to this configuration, the first captured image is erased from the storage unit 22 of the control device 20 after a predetermined period (for example, two weeks after the image was captured) has elapsed, so that an increase in the amount of data stored in the storage unit 22 can be suppressed.

[0066] Furthermore, when a first input operation (for example, operation of the "Delivery Service" button 204) for starting execution of a predetermined service is received at the collective entrance device 10, a first imaging mode is executed to start capturing a first captured image by the camera 13. With this configuration, capturing of the first captured image starts at the timing when the first input operation, which is the first operation for executing the predetermined service, is executed, which leads to further improvement in security.

[0067] The present invention is not limited to the above-described embodiments, and can 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 invention can be achieved.

[0068] In the above embodiment, the authentication unit 21a collates both the service information included in the unlocking request signal received from the mobile terminal 70 and the service information received from the collective entrance device 10 with the information in the data table 51a stored in the server 50 to determine whether or not the information matches, but this is not limited to this example. For example, the authentication unit 21a may execute authentication by collating only one of the service information included in the unlocking request signal received from the mobile terminal 70 and the service information received from the collective entrance device 10 with the information in the data table 51a.

[0069] In the above embodiment, in step S18 of FIG. 4, if the information included in the unlock request signal matches the information in the data table 51a, a series of consecutive image data, namely, the first captured image and the second captured image, are transmitted to the room master unit 30. However, this is not a limitation. For example, the first captured image and the second captured image may be transmitted to the room master unit 30 as discontinuous image data, each captured for a different time period, rather than as a series of consecutive image data. In this case, an image captured by the camera 13 for a predetermined time period from the time a touch operation of the "Delivery Service" button 204 on the initial screen 200 is accepted is set as the first captured image, and then image capture by the camera 13 is temporarily stopped. Then, in step S6, image capture by the camera 13 may be restarted and the resulting image may be set as the second captured image. [Explanation of symbols]
