摘　　要：介绍PLC与触摸屏技术在排气机监控系统中的应用,在该系统中由PLC读取外部信号,发出主控指令,通过触摸屏写入工作参数,显示工作状态,实现人与机器的信息交互,由触摸屏和PLC组成的人机界面大大增强了系统的可视化和可操作性。The application of PLC and touch screen in the monitoring system of the exhauster is presented in this paper. In the system, external signals are read in and main control instructions are sent out by the PLC. Work parameters are input and work states are displayed on the touch screen. Mutual communication between man and machine is implemented. Visualization and operability are enhanced greatly by HMI composed of PLC and touch screen.
