RS-485总线可靠性应用研究

Applied Research on the Reliability of RS- 485 Bus

电力电子装置中常需要在恶劣的电气环境中进行远距离通讯,本文就RS-485在实际系统中的可靠性应用进行了理论分析。分别从线路网络配置、瞬变电压、反射干扰、共模干扰等方面,针对不同的情况研究不同的解决方法来提高RS-485系统的可靠性,具有一定的实际应用价值。

Power electric equipment often requires remote communication in very bad electricity environment. The paper analyses the RS- 485 bus reliability applying to actual system in theory. And basing on the different conditions, it researches practicable ways to improve the reliability of RS- 485 bus system, respectively from different aspects such as network configuration, transient voltage, the reflection interference and common mode interference.
