摘要
介绍一种用于RS485通信故障诊断的便携式检测仪。该仪器将485总线信号分解成十个信号指标,利用单片机及其他附属器件实现对通信状况进行分析、诊断、显示,有助于对通信故障进行排查。其基本原理也适用于其他通信方式的查找。
A portable detecting instrument which applied in RS485 communication faults diagnosis is introduced in this paper.It cans transform the RS485 bus signal into ten kinds of signal index.Single-chip processor and other additional parts were used to analyze,diagnose and display the communication process,thus it can be used to remove the communication fault.The fundamentals of the instrument are also applied in other communication form fault-detecting.
