Power distribution information collection system and distribution side information collection device

Abstract

The invention discloses a distribution information collection system and its distribution side information collection device, wherein the distribution information collection system comprises at least a distribution collection terminal used for carrying out analog-digital conversion of distribution information collected from a distribution network site plant to a digital electric signal and packaging the converted digital electric signal and a terminal identifier of the distribution collection terminal into data packets and outputting the data packets, a monitoring center and a photo-communication module. The photo-communication module and each distribution collection terminal are connected through a serial bus. The photo-communication module is used for receiving the data packets outputted from each distribution collection terminal and converting the received data packets to optical signals supporting communication protocol of an optical fiber communication network and transmitting the optical signals to the monitoring center through the optical fiber communication network. With the application of the system, communication reliability and communication speed are raised.

Description

technical field [0001] The invention relates to the field of power distribution networks, in particular to a power distribution information collection system and a power distribution side information collection device. Background technique [0002] Distribution information acquisition system plays a very important role in the monitoring of power distribution network. For example, in many distribution network sites, it is necessary to regularly collect and analyze the data of the field equipment in the distribution network through the distribution information collection system, so as to understand the basic situation of the field equipment in time, and then monitor the entire distribution network in real time. [0003] At present, in the power distribution network, the distribution information collection system based on GPRS (General Packet Radio Service) technology is commonly used, mainly including distribution collection terminals supporting GPRS communication, GPRS commun...

Problems solved by technology

[0004] However, in the existing power distribution information collection system based on GPRS technology, when transmitting information through the GPRS communication network, the transmitted information needs to be diffused into the atmosphere in the form of electromagnetic waves. Therefore, the GPRS communication network is vulnerable to electromagnetic interference and weather Influence, there are deficiencies such as poor anti-interference ability, low stability, and slow transmission speed

In this way, the communication reliability of the power distribution information collection system based on GPRS technology will be low and the communication speed will be slow
