摘要
论述了某发电厂输煤系统的设计流程、总体结构和软件结构。该系统采用具有国际先进水平的三级分布式计算机控制网络、综合实时管理系统和图形监控等先进技术，实现了电厂输煤系统的自动控制和监测。在下位机控制软件编程中，采用级式语言编程，有效地缩短了系统扫描时间和响应时间。
The design flow,system architecture and its software structure of the coal feeding
system in power plant is introduced in this paper.The systsm,by adopting the international
advanced techniques such as three-stage DCS,timely managemen system and the graphic
monitoring,can realize the automatic control and monitoring of coal-feeding in power plant.And by
using stage programming,it also can decrease the system scanning time and responsing time.
