摘要
介绍了RS-485通信网络和浪涌产生的形式、原因,针对不同形式的系统浪涌对RS-485总线通信网络正常工作的影响,提出了隔离、规避以及两者相结合的防护措施,并结合整个通信系统给出了正确选择保护方式的方法,为防浪涌技术的发展,提供了借鉴。
The causes and forms of surge, the RS-485 communication network were intorduced. Aiming at different forms of system surge that affect the RS-485 bus communication network normal operation, the protective measures of isolation, avoidance and combination of both were presented. The way how to correctly choose protection method was given by combining the entire communications system. It provides reference for the anti-surge technology.
