Method for device access and device communication in building intercom system

Abstract

The invention provides a method for device access and device communication in a building intercom system. A newly added device transmits device number and IP (Internet Protocol) address to other devices in the network; an original device stores the number and the IP address of the device, and simultaneously transmits own number and IP address to the newly added device, in this way, under the condition of regular communication, all the devices in the network store the IP addresses of other devices, and the IP address of a target device can be obtained just by native query without querying a management central computer every time in the communication, and thus the load on the management central computer is reduced, the communication efficiency is improved, and even under the condition of failure of the central computer, the interrupt of the integral communication cannot be caused.

Description

technical field [0001] The invention relates to a device access communication method, in particular to a device access and device communication method in a building intercom system. Background technique [0002] In the current building intercom system, in order to achieve communication between multiple devices, each device needs to be connected to the network, and each call must first query the IP of the target device from the management center to establish communication. Or use pure broadcasting to find the required equipment. [0003] The Chinese patent application number 200710165787.7 provides a broadband video service access method, including the following steps: A. When the central office access device receives the video program playback request information, it queries the central office access used to receive the information The port of the device; B. query the video user table to obtain the corresponding authority number of the port; query the access authority table...

AI Technical Summary

Problems solved by technology

With this method, each remote device has a unique device identifier, which is beneficial to the management of the device, but each device must first receive the broadcast frame to obtain the communication address, and cannot establish a direct communication channel for the device

[0005] In building intercom, usually a user calls a limited number of devices. If you have to query these device numbers through the server every time, although the success rate of the query is high, the dependence on the server will be virtually increased, and the average response time will also decrease. long
