A first relay driver 10 for driving a first relay 16 by inputting a home video transmission enable signal from the controller when an object is detected from a common entrance interphone of a jurisdiction; 14) and a second relay driver 12 for driving the second relay 18 by inputting an entrance video reception enable signal from the controller, and an image signal input through the first relay 16. A video divider 22 for distributing and outputting to a self-governing generation device or to another common entrance intercom, and presenting from the controller Is composed of a third relay driving unit 20 to drive the third relay 14 to the input video transmission enable sinhoeul to transmit the video signal output from the video divider 22 in the other joint video intercom.

5 is a flow chart illustrating a control signal generation for transmitting an image when a visitor is detected in the common hall according to the present invention.

In order to implement the present invention, by receiving the image of the camera embedded in the intercom installed in the common entrance control the first to third relays (16, 18, 20) according to the detection of the visitors to the desired image to monitor each generation device You should be able to. In addition, it is well known that data exchange between interphones installed in a plurality of common entrances exchanges information with another data dedicated line, and the present invention will be described based on this.

First, in step 51, the control unit of the plurality of common entrance intercoms 201, 202, and 203 checks whether there is a visitor detection in the self-governing common entrance, and proceeds to step 52 when there is no visitor detection in the self-governing common entrance and there is a visitor detection from the intercom of another common port. . In step 52, the controller generates an entrance video reception enable signal. The generated porch video reception enable signal is applied to the base of the transistor Q10 through the resistor R30 to drive the transistor Q10. When the transistor Q10 is driven, current flows in the coil of the second relay 18 to connect the switch to the image divider 22 through the visitor image signal input through the cavity image connection terminal 24. The visitor video signal input through the video connection terminal 24 is distributed through the video distributor 22 and transmitted to the corresponding generation device. Therefore, each household device can monitor the visitor's video when there is a visitor to the common entrance rather than to his or her jurisdiction.

However, when the visitor is detected in the self-governing common entrance in step 51, the controller proceeds to step 53 and the control unit generates a home video transmission enable signal. The generated home video transmission enable signal is applied to the base of the transistor Q9 through the resistor R29 to drive the transistor Q9. When the transistor Q9 is driven, a current flows in the coil of the first relay 16 so that the first relay 16 connects the visitor image signal output from the camera to the image distributor 22. At this time, the video divider 22 distributes the visitor video signal and transmits them to the self-managing generation device. In step 54, the controller generates an entrance video transmission enable signal. The generated porch video transmission enable signal is applied to the base of the transistor Q15 through the resistor R119 to drive the transistor Q15. When the transistor Q15 is driven, current flows in the coil of the third relay 20 so that the first relay 20 receives the visitor image signal output from the image divider 22. Connect with The visitor video signal output through the common entrance video connection terminal 24 is applied to another cavity door interphone to perform the same operation as described above to transmit the visitor video signal to the self-managing household device. For example, when a visitor image is detected from the camera of the cavity door interphone 201, the controller of the cavity door interphone 201 generates a home video transmission enable signal and applies it to the first relay driver 10. At this time, the first relay driver 10 drives the first relay 16 to apply the visitor image signal captured by the camera installed in the cavity door intercom 201 to the image distributor 22. Then, the video divider 22 distributes the visitor video signal and outputs the visitor video signal to the corresponding generation device 101 to display the visitor image on all monitors of the generation device 101. Thereafter, the controller of the common entrance intercom 201 generates the entrance video transmission enable signal and applies it to the third relay driver 14. At this time, the third relay driver 14 drives the third relay 20 to output the visitor video signal output from the video distributor 22 to the common entrance video connection terminal 24. The visitor video signal output to the video connection terminal 24 is applied to the cavity door interphone 202 and the cavity door interphone 203. In this case, the control unit of the cavity entrance interphone 202 and the cavity entrance interphone 203 generates the entrance video reception enable signal and applies it to the second relay driver 12. In this case, the second relay driver 12 drives the third relay 18 to apply the visitor image signal input through the image distributor 22 to the image distributor 22. Then, the video divider 22 distributes the visitor video signal photographed from the camera of the common entrance intercom 201 and outputs it to the corresponding generation devices 102 and 103 so as to display all of the generation devices 101 and 103. Display visitor video on the monitor. For convenience of description, three common entrance intercoms have been described as an example, but three or more common entrance intercoms can be installed to monitor visitor images with more household devices.

As described above, the present invention has the advantage of accurately monitoring the visitors of all the common entrances by distributing the image of the common entrance to each household regardless of the staircase or corridor architecture. .
