摘要: 针对热连轧生产线特点自行设计了符合现场实际要求的基于Windows的热连轧过程控制系统应用平台.平台采用多进程结构,进程内部采用一任务一线程的新型模式,大大提高了系统的稳定性,降低了各功能模块间的耦合性.平台的功能包括进程管理、网络通信、数据采集和数据管理、过程跟踪.数据通信、数据库操作和过程数据记录、带钢跟踪和线程调度分别由以上几个功能负责.平台采用高速的事件信号触发方式来调度模型计算.该平台已经成功应用于国内多家热连轧带钢生产现场,运行稳定可靠.

Abstract: Taking the characteristics of a hot strip rolling line into account, a Windowsbased platform of the process control system was designed and developed to meet the actual requirement on the spot. The platform adopted multiprocess structure and each process adopted a new mode of “one task one thread”, which improved the system stability and reduced the coupling of functional modules. The key functions of the platform included process managing, network communicating, data collecting/managing and process tracking. Data communicating, database operating and process data recording, and strip tracking together with thread dispatching were implemented separately by these modules mentioned above. Each module was scheduled by an event signal trigger method which had shorter response time. This platform successfully ran on some hot strip rolling lines with good stability and reliability.

Key words: multiprocess, multithread, multitask, process control, hot strip rolling
