H9000系统中LCU之串行通信

Serial communication of LCU in H9000 system

随着对水电厂计算机监控系统数据采集要求的不断提高,数据采集的方式多样、范围日趋扩大,串行通信方式采集数据已被广泛采用。与LCU通信的主要是各种辅机系统、各种智能仪表。根据使用场合、方式及外围设备的不同,可以采用多种通信机等方式,本文主要介绍我所自行开发研制的H9000水电厂计算机监控系统中经常采用的几种通信方式。

Many efficient data are acquired for the computer supervision and control system of hydropower station.The serial communication is widely used for date acquired now. It includes communication with auxiliary systemsand intellectualized meters. H9000 computer supervision and control system uses several serial communicationmodes, i. e. the local computer, intellectualized communication module, local operator station, communicationcontroller, system communication computer.
