利用串口通讯监听技术快速判断监控系统通讯故障

摘要

The paper introduces the application of serial communication monitoring technology in locating the en‐try points of interference signal fast and accurately and monitoring the interference of variable frequency and power and the communication line losses by narrowing the range of network detection area without detecting ev‐ery equipment and cable ,w hich has shortened the location time and solved the communication faults considera‐bly .%利用串口通讯监听技术能层层缩小网络检测区域范围，避免了每台设备、每段线缆进行检测的麻烦，大大缩短了排查时间，而且准确快速查找出干扰信号侵入点，尤其对变频干扰、电源干扰、通讯线路损伤监测作用明显，是解决困扰监控通讯故障的法宝。
