| 摘 要： | 以两柱掩护式液压支架为例,介绍了一种基于S7-300 PLC的液压支架自动控制系统的设计。该系统采用控制系统软件对安装在立柱上的压力、下缩量、倾角等传感器测得的数据进行智能分析,实现对电磁阀组的启停,使液压支架自主运行。实际应用表明,该系统实现了对井下液压支架的远程实时在线监测和控制。

| Abstract: | Taking two-leg shield hydraulic support as example,design of an automatic control system of hydraulic support based on S7-300 PLC was introduced.The system makes intelligent analysis with software of control system for data measured by sensors of pressure, shrinkage and angle which are installed on column,so as to realize start-stop of magnetic valves,which can make autonomous operation of hydraulic support.The actual application showed that the system realizes on-line monitoring and control real-timely for hydraulic support of coal mine underground. |
