东深供水改造工程泵站微机保护网络

Introduction of Pumping Station Microcomputer Protection Network System in Dongshen Water Supply Improvement Project

东深供水改造工程微机保护系统分为工业总线网络和光纤通讯两部分 ;工业总线网络采用了Profibus通讯协议 ,该协议具有反应时间短 ,抗干扰性强的特点 ;光纤通讯则具有反应时间不受电磁场和电磁辐射的影响等特点。

The pumping station microcomputer protection network system of Dongshen water supply improvement project includes industry bus network and fibre communication; the former adapts to Profibus communication agreement whose reaction time is very short and the ability of resisting disturbance is strong. the fibre communication has many properties, for example, reaction time is not affected by electromagnetism field and electromagnetism radialization.
