摘要：本设计主要是要研究恒压供气控制系统的硬件电路、恒压变频供气的控制方法、开发基于MCGS 组态软件的监控界面。整个系统是用PLC进行控制， MCGS 组态软件进行监控。 PLC 主要控制空压机的启动和停止，MCGS 用于读取压力，以便我们随时了解系统信息，进行调整。整个系统自动化水平比较高，大大减少了人力物力，而且对于压力的变化能很快的做出反应，调节压力。该系统结构简单、成本、性能稳定，而且功能齐全，非常适合应用和推广。关键词： MCGS 组态软件； PLC；空气压缩机Designs based on the PLC air compressor's supervisory systemAbstract: This design is mainly needs to study the constant pressure air feed control system's hardware circuit, the constant pressure frequency conversion air feed control method, the development based on the MCGS configuration software's monitoring contact surface. The overall system is carries on the control with PLC, the MCGS configuration software carries on the monitoring. The PLC primary control air compressor's start and the stop, MCGS uses in reading the pressure, so that we momentarily can understand the system message, makes the adjustment. The overall system automation level is quite high, reduced the manpower and resources greatly, moreover can very quick make the response regarding the pressure change, the adjustment pressure. This system structure is simple, cost, stable property, moreover the function is complete, very suitable to apply and the promotion. Key word: MCGS configuration software。 PLC 。 Air compressor第 1 章 绪论1.1 空气压缩机的发展与现状随着微型计算机技术和自动控制技术的不断进步与发展，许多领域中都引入了计算机自动检测与控制技术。在煤矿中甚至许多有风动机械的企业，因工作性质的需要，都离不开空气压缩机。目前空气压缩机的种类很多，按工作原理可分为容积式压缩机,往复式压缩机 ,离心式压缩机 ,容积式压缩机的工作原理是压缩气体的体积，使单位体积内气体分子的密度增加以提高压缩空气的压力；离心式...
