摘要
针对目前矿用电动阀门自动控制系统存在可靠性不足、不能实时显示故障原因和运行参数、无主触点是否吸合判断、维修困难等问题,新型PLC和触摸屏控制的矿用电动阀门智能监控系统的设计,解决了上述问题。实现了对电动阀门的各种智能控制、显示、保护等功能及防爆要求。阐明其总控制原理,给出了监控系统电气原理图、程序设计流程框图和触摸屏界面,分析说明了设计中遇到的各种难题和解决方法。实际应用表明本系统性能先进、效果良好。
Aimed at the mine electric valve automatic control system reliability deficiencies exist, the cause can not be real-time display and operating parameters, without the main contacts are energized judgment, maintenance difficulties and other issues, the new PLC and touch screen control intelligent electric valve mine monitoring system designed to solve the above problems. Achieve a variety of intelligent electric valve control, display, and other functions and explosion protection requirements. Clarify its total control principle, gives the control system electrical schematics, program design and touch screen interface flow diagram and solutions. Practical application analysis illustrates the various problems encountered in the design shows that the system performance advanced to good effect.
