真空熔药机自动化控制技术

Automatic-Control Technology of the Vacuum Explosive Melting Machine

系统采用计算机与PLC相结合的控制方式,通过工业控制网络将计算机、可编程控制器、现场检测仪表和执行器集成为一体,实现了集中管理、监控,分散控制和单元控制的目标。采用绝对编码器实现了熔药机转速和位置的实时测量,通过程序实现了熔药机停止定位。系统具有手动、自动功能;良好的人机对话功能,实现了熔药自动化。

The combination of computer and PLC was adopted in the explosive melting machine measuring and controlling system. The system was composed of computer monitor system, PLC control system, apparatus and meter system, power and vacuum assistant system. The computer, PLC and spot instrument were combined by industrial control net. Thus centralized management, monitor, dispersive management and units management were realized. The absolute encoder was adopted, so the rotate speed and position of the machine could be measured in real time. The machine could be operated manually or automatically, Human-machine intercommunion was all right and all the operation of the machine could be performed on the computer.
