Description

Anti-interference wiring structure of dispatch telephone

Technical Field

The present invention relates to dispatch telephones, and more particularly to an anti-interference wiring structure for dispatch telephones.

Background

The power dispatching telephone is a special power dispatching telephone command network, is an important communication means for ensuring safe production and operation of a power grid, and has high reliability and high connection speed. The existing running analog relay communication mode cannot carry out dispatching telephone networking and can not meet the requirement of power dispatching telephone development. The communication lines built in sequence in the power communication network enable the power communication network to gradually build a digital communication ring network, which provides necessary conditions for realizing full digital exchange of dispatching telephones.

The dispatching telephone is an important way for the communication between the power plant and the power grid and the instruction receiving, and the data receiving and signal stability of the dispatching telephone are very important. Pcm (pulse Code modulation) is one of the encoding methods for digital communication. The main process is to sample the analog signals of voice, image, etc. at regular intervals to make them discretize, at the same time, to round the sampled values by hierarchical unit to make them be rounded and quantized, and at the same time, to express the amplitude of sampled pulse by a group of binary codes. As shown in figure 1, a pair of digital signal telephone lines are led out from PCM for a power plant end signal to a dispatching telephone distribution frame of a booster station, then the power plant end signal passes through the telephone lines with the length of more than 200 meters to a comprehensive distribution frame in an electronic room of a centralized control building, and then the power plant end signal is transferred to a length station.

Although the dispatching telephone provides a basic communication means for the production and operation of the power grid and can meet the daily communication contact of a dispatcher, the existing dispatching telephone still has many defects. Firstly, the distance from the booster station to the centralized control building is 200 meters, and the data signal transmission is attenuated. Secondly, there are cables of different voltage classes, such as 400V or 6KV, on the cable tray path from the booster station to the central control building, which can interfere with the telephone signals, which are inherently fragile. Finally, the telephone transfers from PCM presence to value long 3 patch panels, each transfer also contributing to data corruption to varying degrees. The end result is poor call quality, signal instability, call noise, etc.
