现行在线监测系统总线的研究与分析

Research and Analysis on the Current on-line Monitoring System Buses

针对电力系统在线监测使用较多的RS-485、CAN和LonWorks进行具体分析。结合在线监测系统的要求和特点,对比RS-485、CAN和LonWorks,得出在经济和可靠的双重考虑下RS-485系统总线仍然是目前在线监测首选的结论。针对应用前景较好的FF现场总线,亦有论述和分析。

In view of the on-line monitoring in power systems,more RS-485,CAN and Lon Works use are analyzed.Combining the requirements and characteristics of the on-line monitoring system,RS-485,CAN and Lon Works are compared.It shows that RS-485 system buses are still the first conclusion under both economy and reliance.For fine FF field buses prospect,both discussion and analysis are put forword in the paper.
