摘要
对一个把CAN总线应用到分布式变电所自动化系统的例子进行了分析,对于分布式变电所自动化系统来说,通信网络的效率、安全性和实时性具有重要意义,在实际工作中,通过在现行测量、控制和保护单元外增加一个RS232和CAN总线之间的转换器,构成变电所自动化系统的现场总线网络,试运行情况表明:该方案完全能满足系统的要求。
A case of application of CAN bus on the distributed automatic system of substation is illustrated. To meet the need of automatic control system of substation, a network is necessity because of the distributed control units of the substation. To shorten the developed period of the system, an interface bridge between the RS232 and CAN bus is made. The result of test run shows that the requirements of system can be satisfied by the project.
