Full-digital building intercom system and authentication method based on session initiation protocol (SIP)

Abstract

The invention discloses a full-digital building intercom system and an authentication method based on a session initiation protocol (SIP). The system comprises a main control server, a unit door machine and an indoor machine, wherein the main control server comprises a main control SIP service module, and a main control data and authority management module, the unit door machine comprises a unit SIP service module, an intercom entrance guard module and a unit data module, and the indoor machine comprises an indoor machine SIP communication module, an intercom unlocking module and a user data module. The full-digital building intercom system achieves area control of divided units and self-checking mechanisms, solves the problems that an intercom system in an existing digital building is poor in independence application, blocked in network, lost in failure self-checking and the like, and improves application, stability and reliability of the system.

Description

technical field [0001] The invention relates to an all-digital building intercom system and an authentication method based on a session initiation protocol SIP (Session Initiation Protocol), belonging to the field of digital control. Background technique [0002] The traditional building intercom system uses an analog or digital-analog hybrid structure. There are many problems in this type of technical architecture: complex networking, poor anti-interference, short transmission distance, many busy lines, and large amount of wiring engineering. Judging from the current use of the community, the difficulty of networking is the biggest problem. In recent years, with the development of the integrated circuit industry and the advancement of communication technology, a digital building intercom system has emerged. Due to the use of standard TCP / IP protocol and Ethernet structure, it has excellent networking integration capabilities and can solve previous problems. . However, the...

AI Technical Summary

Problems solved by technology

[0002] The traditional building intercom system adopts an analog or digital-analog hybrid structure. There are many problems in this type of technical architecture: complex networking, poor anti-interference, short transmission distance, many busy lines, and large amount of wiring engineering, etc.

In this way, if you want to realize the simplest building intercom function in a unit of the general analog intercom mode, it cannot be applied without a management console.

[0005] 2) There is a high risk of network congestion

[0006] The digital building intercom system generally broadcasts and transmits video files from the switchboard to all terminals, which will cause a lot of network pressure and may cause network congestion, which will affect the normal door phone calls

[0007] 3) Fault self-test missing

[0008] Some key resident equipment in the digital building intercom system, such as the door station of the unit, if there is a failure, it cannot be detected in time
