摘要
本文探讨了一种分散型传感检测信号载波数据通讯新方法.它特别适合于中距离(100M～2000M)分散检测集中数据采集处理的场合,如水利系统中室内模型试验和原型大坝观测的数据通讯.该方法采用220V交流动力电源线作为传输信道,将被测传感信号分时地以串行码方式,调制后加载到动力线路上,从而免去了传统上大量的电缆线路铺设,达到经济之目的.
In this paper, a new carrier data communication method for distributing measurement signal has been introduced. It is suited to medium distance (about loom-2000m)communication in the distributing measurement system. In this system the measurement signal is converted to data signal and then by modulation the signal is transmitted to ~220V power line: By this method, a large quantity of electric cable is saved, and high precision measurement can be realized:
