基于网络控制的水泥转窑监控系统

Distributed Control System Based on Control Net for Cement Rotary Kiln

基于网络控制的水泥转窑监控系统由多个分布式现场控制网络和连接各中心工作站的系统网络组成。控制网络现场总线采用物理层、链路层和应用层结构。链路层以主从循环查询获取数据。应用层以DLL收发数据和超时处理等服务。中心工作站检测和控制现场设备,动态显示工艺流程和现场数据并报警,统计查询生产信息等。

Distributed control system based on control net for cement rotary kiln consists of multi distributed control networks and system network connected center workstation. The structure of physical layer, link layer and application layer was applied in field-bus of network control, data was gained through cyclic query of principal and subordinate PC in link layer. DLL receives and sends data, and processes overtime service. Center workstation tests and controls field equipments, dynamically display technical process, field data and alarm, production information for statistical query.
