摘　　要：研发出了一种气道试验台的自动测控系统,通过传感器、PLC及上位机完成数据的采集、自动记录数据并打印且能实现气门升程的自动调节,PLC通过PID计算自动调节流量控制阀,能够实现定压差测量。The automatic system of measurement and control of air port blowing test bench for inter- nal combustion engines was developed in this paper. It can complete data-acquisition, complete data acquisition, automatic recording data and print, and can adjust the lift-distance of the intake valve automatically via computer, PLC and sensors. The PLC can adjust the flowing control valve automati- cally, which can realize the measurement of constant pressure.
