输煤控制系统硬件结构与上位机监控软件设计

摘要

根据工况将不同的设备组合成不同的工作流程，以集散控制技术为基础，应用PLC网络实现了对输煤设备的现场控制、电控室控制和中控室控制。并以FIX软件为工具，通过定义PLC的I/O端口映射表方法，以时间、事件、故障为触发手段，设计了实时监控软件，并实现了输煤量与数据库系统的数据接口。%The different equipment is organized to form the certain workflow according to the work status and the PLC network is used to control the port equipment, which achieves three class control. The real-time inspection-control software of the upper-computer is designed by defining I/O port mapping table and taking the time, event, defect as trigger.
