To make comparison easier. Then, the deliveryman inquiry unit 14 generates comparison information in which the converted visitor image and the converted deliveryman image are arranged side by side, and displays the generated comparison information on a display unit (not shown) of the housing information board 3. . In a present Example, by providing a deliveryman inquiry part in an apartment sharing part, the structure of the house information board of each house can be simplified and the raise in manufacturing cost can be suppressed.

  Next, the operation of the intercom system of this embodiment will be described with reference to the control flowcharts of FIGS. In FIG. 7, the left flow shows the operation of the lobby intercom 9, the central flow shows the operation of the apartment gateway 13 and the house information board 3, and the right flow shows the operation of the delivery status inquiry server 61 of the courier company 6. Show.

  First, in S56, the lobby intercom 9 stands by in a state waiting for the “call” switch to be pressed. When the “call” switch is pressed, the determination in S56 becomes Yes, and the process proceeds to S58. The lobby intercom 9 uses the video control panel 10 as a control signal for the house information panel 3 of the selected room number. A call signal is transmitted, and a call signal is transmitted to the apartment gateway 13.

  Here, in order to distinguish between a normal visitor and a call by a courier delivery person, the lobby intercom 9 displays, for example, “For courier, please press“ * ”and“ Call ”” Do what you want to do. If the “*” switch is pressed immediately before the “call” switch is pressed, or if the “call” switch and the “*” switch are pressed at the same time, it can be specified that the call is made by a delivery person. it can. Thereby, the lobby intercom 9 can distinguish between a call by a normal visitor and a call by a delivery person of a courier (or a visitor posing as a delivery person). The call signal transmitted from the lobby intercom 9 to the condominium gateway 13 is different from the call signal due to a call by a delivery person and the call signal due to a call by a person other than the delivery person.

  When the house information board 3 receives a call signal from the lobby intercom 9 in S60, it generates a ringing sound in S62. Next, in S64, the apartment gateway 13 determines whether or not the delivery person is calling based on the calling signal. If it is not a delivery person's call, the apartment gateway 13 does nothing.

  If it is determined that the delivery person is calling in the determination in S64, the apartment gateway 13 transmits a collation information presentation instruction that prompts the visitor to input collation information to the lobby intercom 9 in S66. In S68, the lobby interphone 9 receives the collation information presentation instruction, and in S70, the lobby interphone 9 converts the audio signal of the collation information presentation instruction into a voice and outputs it from the speaker unit 25 as a voice. For example, “For courier, enter the courier code number from the numeric keypad and press“ # ”, enter the slip number from the numeric keypad and press“ * ”. ”To prompt the user to enter the delivery company code and slip number. This automatic reception function eliminates the need for the user to prompt the delivery person to input verification information, improving convenience.

  Next, in S <b> 72, the lobby intercom 9 accepts the input of the delivery company code number and the slip number from the operation unit 23. In S74, the lobby intercom 9 determines whether or not the input is completed. Specifically, if “#” is input after the delivery company code number and “*” is input after the number of the slip number is input, it is determined that the input is completed. If the input is not complete, the process returns to S72.

  If the input is completed in the determination in S74, the lobby intercom 9 proceeds to S76, and transmits the delivery agent code number and the slip number input from the operation unit 23 to the apartment gateway 13 as collation information.

  In S <b> 78, the apartment gateway 13 receives the delivery agent code number and the slip number from the lobby interphone 9 as matching information from the lobby interphone 9. Next, the internal storage unit of the delivery person inquiry unit 14 is searched by the courier code number to obtain the URL of the courier company, and the courier company is transmitted via the Internet 5 using the URL of the courier company and the slip number. 6 is sent to the delivery status inquiry server 61 of No. 6 for the delivery status of the delivery of the slip number.

  In S80, the delivery status inquiry server 61 of the courier company 6 receives the delivery status inquiry. Next, in S82, the delivery status inquiry server 61 searches the delivery status management database 62 by the slip number and reads the delivery status of the package with the slip number. If the delivery status indicates that delivery from the delivery branch to the delivery destination is in progress, the delivery status management database 62 stores a delivery person identification number responsible for delivering the package of the slip number. Therefore, if the delivery status is being delivered from the delivery branch to the delivery destination, the delivery person identification number is simultaneously read together with the delivery status. Next, in S84, the delivery status inquiry server 61 searches the delivery person database 63 by the delivery person identification number, reads the delivery person image of the delivery person identification number, and sends the delivery person image together with the delivery situation via the Internet 5. Transmit to the condominium gateway 13.

  In S86, the deliveryman inquiry unit 14 of the apartment gateway 13 receives the delivery status and the deliveryman image as reference information. Next, in S88, the deliveryman inquiry unit 14 determines whether the delivery status is being delivered from the delivery branch to the delivery destination. If delivery is not in progress, the deliveryman inquiry unit 14 performs delivery status abnormality processing. In the delivery status abnormality process, for example, the display unit of the house information panel 3 displays that the delivery status is abnormal together with the name of the courier company, or displays the inquiry telephone number for the courier company. This telephone number may be stored in advance in the deliveryman inquiry unit 14 and read as necessary. At the same time, if the system has a manager resident in the condominium sharing unit 8, the integrated panel 11 may be notified of the abnormal delivery status, or may be informed to the condominium management company or condominium security company.

  If it is determined in S88 that the delivery status is under delivery, in S90, the deliveryman inquiry unit 14 generates a comparative image arranged side by side by aligning the feature points of the visitor image and the deliveryman image, and housing information It displays on the display part of the board 3. The details of the processing content of S90 are the same as the processing content described in the first embodiment with reference to FIG.

  Next, if there is an input of the unlocking switch from the house information board 3 in S92, the deliveryman inquiry unit 14 outputs an unlocking signal from the integrated board 11 to the autolock 12 in S94, and the process is terminated. If it is not an input of the unlock switch in the determination of S92, if an instruction for registering a suspicious person image is input in S96, the delivery person inquiry unit 14 in S98, along with the date and time information, the visitor image and the input courier The code number and the slip number are stored in the delivery person inquiry unit 14 and the process is terminated. At this time, the deliveryman image and the comparison image may be further stored. It is preferable that the stored content can be arbitrarily read and displayed by operating the house information panel 3. If it is determined in S96 that there is no suspicious person image registration instruction, other processes are appropriately performed.

  While the preferred embodiments have been described above, they are not intended to limit the invention. It goes without saying that various modifications can be made in accordance with the design and the like as long as the technical ideas according to the present invention are not deviated from those other than these examples.
