Intercom system terminal device as well as intercom system and communication method thereof

Abstract

The invention discloses an intercom system terminal device as well as an intercom system and a communication method thereof. The intercom system terminal device comprises an input device for inputting terminal information, an IP acquisition module, a processor and a communication module, wherein the IP acquisition module is used for using a polling list mode to acquire IP address information according to received terminal information; the processor is used for receiving the terminal information input by the input device, sending the terminal information to the IP acquisition module and sending communication command information to the communication module when acquiring the IP address information; and the communication module is used for sending communication data to a terminal device corresponding to the IP address information according to received communication command information or receiving communication data from Internet. In the invention, the IP address information is acquired through using an IP polling mechanism inside a terminal, thus ensuring the normal operation of communication work of cell visual intercom systems in the condition that the work of a server is interrupted.

Description

technical field [0001] The invention relates to the technical field of an intercom system for community communication, in particular to an intercom system terminal device, an intercom system and a communication method thereof. Background technique [0002] With the development of the housing market, especially in our country's housing, the analog video intercom is gradually transitioning to the digital video intercom, and the communication network has also become a standardized TCP / IP network; the entire network structure is simple, and the construction and maintenance costs are low. , Terminal functions are also very rich, bringing great convenience to residential users. [0003] To communicate on the Internet, related protocols are generally required. At present, most network communications use the SIP (Soft Switch) protocol. The communication mechanism is as follows: figure 1 As shown, a plurality of communication devices M, N, Q and S are respectively connected to the S...

AI Technical Summary

Problems solved by technology

Due to the high maintenance cost, in order to reduce the cost, the community property generally chooses ordinary PC as the server, so after the server works for a long time, the server is prone to failure

If the server fails, the intercom communication of the entire community will be paralyzed, and all terminals will not be able to communicate

In particular, because there is no way to communicate, the door (electronic lock) of the unit cannot be opened normally by the intercom system
