PCM Electricity Liquid Gathering Valve with Embedded Single-chip Microcomputer Control System

本文研究 PCM 电液流量集成阀单片机控制系统,利用单片机输出的二进制编码去控制电磁阀的开关,输出近似连续的流量和压力。整个系统包括接受给定,检测和控制三个环节,通过检测现场信号与给定的偏差,经过数字处理后输出脉码控制电磁阀的开关,从而完成系统流量的控制。

This paper introduces the computer control system of PCM electricity liquid gathering valve.The switching of electromagnetism valve is controlled by a single microcomputer binary code output.The system includes three links:accepting setting,testing,and control.After testing the difference between the spot signal and the giving signal,and then taking it digital handling into output codes,controls the on-off of the electromagnetism,valve,thus implementing the controlling of the flow of the liquid.
