基于SC1128的瓦斯远程监测系统设计

ccording to the frequent dangerous gas accidents underground and the reality that the existing gas monitoring system is wired difficultly as well as high cost,a new network monitoring system based on powerline carrier technology is designed in the paper,the devolopment for the node hardware is according to the PLC chip SC1128 released by Beijing Zhiyuan Corporation.The system includes the controlling unit and the gas gathering unit so that it can be uploaded thegathered data to monitoring center through the low voltage powerline and overcomes the intensed disturbnce and the large weaken scope successfully in the low voltage powerline communication, realizing to the damp gas long-distance monitor.The test shows that the monitoring system can work normally and reliable,having certain application value and the market prospect.
