摘要
针对大中型工业控制系统直接通过人工检测难以及时准确检测出故障点的情况,设计一种在线故障检测系统,采用西门子系列PLC和触摸屏,结合现场传感器实现自动在线故障检测。系统的主要运动元件为气缸,气缸在两个位置间作往复运动,PLC通过电磁阀控制气缸运动,对气缸位置的检测则通过气缸上面的行程开关实现。
In some large and middle industry control system, due to more control points and complex construction, it＇s difficult to detect malfunction position by man when it occurs. Design an online error detecting system by adopting Siemens PLC and touch panel. The system cooperates with local sensor to realize the automatic online fault detection. The main drive element of system is cylinder. Cylinder reciprocates between positions; PLC uses electromagnetic valve to control cylinder moving, and the limit switch on cylinder detects the cylinder position.
