摘　　要：以山西晋城某煤矿空压机的自动化改造为背景,分析了设备的运行现状及控制要求;设计了以S7-300PLC为核心控制单元的监控系统,采用WinCC组态监控界面,实现了空压机系统工况的实时监测和集中控制;系统采用了智能PID算法获得变频工况下的最佳给定频率,无需人为设定;通过变频恒压调控机制,实现了供气压力的连续、稳定调节,提高了系统的节能性和安全可靠性。Taking the automation retrofit of a certain Coal Mine in Jincheng,Shanxi Province, as the background, this paper analyses the operating status of the air compressors and the monitoring requirements. The monitoring system uses S7-300 PLC as the core control unit and adopts WinCC configuration software to make the real time monitoring and centralized control come true. The usage of intelligent PID in the system makes it easy to achieve the best given frequency under the variable frequency condition, without manual intervention. With the control mechanism of variable frequency and constant pressure, the gas supply pressure can be regulated constantly and stably. The monitoring system also improves the energy-saving effect and reliability of the air compressor system.
