摘 要
本文针对空压机能耗大、噪音大、自动化程度低等缺点，介绍了基于可编程序控制器技术和变频调节技术的矿井空压机控制系统设计。该控制系统设计以变频器、可编程序控制器作为系统控制的核心部件，由压力变送器检测管网压力值，输入给变频器与给定压力比较,经变频器内部PID运算,控制电机转速的升降,调节管网压力；并通过可编程序控制器控制变频与工频的切换,实现闭环自动调节恒压变量供应压缩空气的目的。通过对空压机控制系统的改造，大大提高了空压机运行的安全性能、节能效果和自动化水平，适应了现代矿山建设的发展要求。

The Design of Mine Pit Air Compressor Control System Based on PLC
Abstract
Concerning the disadvantages of air compressor, such as the tremendous energy consumed, the loud noise and a low degree of automation, etc, the paper introduces the design of min pit air compressor control system based on the PLC and the frequency conversion adjustment technology. This control system is mainly composed of the frequency changer, the programmable logical controller. Through the network pressure value examined by the pressure transmitter and the comparisons between the input-pressure and the assign-pressure, the system, after the frequency conversion interior PID operation, controls frequency conversion or labor frequency through programmable foreword controller to realize the goal of the closed loop automatic control constant pressure variable supply compressed air. With the improvement of air compressor control system, the safety of air compressor performance, Energy-saving and automation level are enhanced to adapted to the modern mine development.
Key words： PLC， Air Compressor，Inverter
