Remote intercommunication structure for interphone

Abstract

The invention provides a walkie-talkie remote communication framework which comprises at least a pair of talking device, an address analysis service device. The communication between the talking device and the address analysis is transmitted by the INTERNET (WAN), and after the boot, the talking device regularly reports to the address analysis service device. When an active calling talking device needs the call, first, the active calling talking device refers to the address analysis service device for the address of a passive calling talking device and then uses the address to call the passive calling talking device which receives the call of the active calling talking device, and then both of the active calling talking device and the passive calling talking device enter a two-way audio and video talking. The walkie-talkie remote communication framework of the invention transmits voice and image on the basis of the existing ETHERNET, solves the problem that the traditional talking equipment is restricted by transmission distance, and realizes the function of audio and video talking in the LAN and that in the WAN.

Description

【Technical field】 [0001] The invention relates to walkie-talkie technology, in particular to a framework for intercommunication between two-way audio and video intercoms in different places. 【Background technique】 [0002] At present, most of the wiring in building intercom adopts bus mode, so data transmission, audio transmission, and video transmission adopt analog bus, which leads to almost no compatibility and interoperability among various manufacturers. In addition, the following problems need to be solved by adopting the bus mode for transmission: 1) The problem of limited transmission distance. As we all know, the signal strength attenuates as the transmission distance increases, so it is necessary to amplify and adjust the signal strength by adding additional equipment, but the transmission distance still cannot be completely solved. 2) Anti-jamming issues, including data, audio and video anti-jamming. Interference includes noise interference, environmental interf...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the wiring in building intercom adopts bus mode, so data transmission, audio transmission, and video transmission use analog bus, which leads to almost no compatibility and interoperability among various manufacturers.

In addition, the use of bus mode for transmission also needs to solve the following problems: 1) the problem of limited transmission distance

As we all know, the signal strength attenuates as the transmission distance increases, so it is necessary to amplify and adjust the signal strength by adding additional equipment, but it still cannot completely solve the transmission distance

2) Anti-jamming issues, including data, audio and video anti-jamming

Interference includes noise interference, environmental interference, etc., which can be transmitted through differential transmission, increased shielding, increased line width, and two-wire / three-wire transmission, but it still cannot completely solve the anti-interference problem

3) Audio and video busy problem

As mentioned above, the traditional intercom has the disadvantages of troublesome wiring, short transmission distance, poor anti-interference ability, poor compatibility and interoperability
