基于网络的熔铸装药生产线控制系统

Control System of Fusion Casting Charge Production Line Based on Network

以PLC可编程控制器和计算机为核心控制设备,采用基于以太网和CC-Link现场总线的技术,在分散控制和单元控制的基础上,全面实现集中管理和监控。其采用2台计算机组成冗余系统;同时还采用人机界面作为参数输入、状态监控的备用手段,操作上按自动、手动两种模式设计;控制程序采用梯形图方式编写,包括初始化程序、主程序、复位程序等。

Make PLC programmable controller and computer as the key control equipment, and use technologies based on ethernet and CC-Link locale bus, realized centralized control and monitor on the basis of decentralized control and unit control. The system is made up of two computers. Meanwhile, adopt man-machine interface as auxiliary method for parameter input and behaviour monitor. According to two model design of self-action and auto-manual on the manipulate, the control program is compiled in ladder drawing, which comprises initial program, main program and reset program, ect.
