摘要
系统以PLC为控制核心,通过总体设计、硬件设计、上位机设计,实现了对矿井局部通风机的变频调速,可实现自动和手动2种控制方式,并通过上位机监控系统的设计,能实时监测瓦斯浓度、压力,当发生危险时能及时报警。实践表明,系统精度较高,有一定的应用价值。
The system takes PLC as the control core,through the overall design,hardware design and host computer design,the frequency conversion speed regulation of the local fan is realized,and automatic and manual control can be achieved in two ways,and through the computer monitoring system design, real-time monitoring of gas concentration and pressure ,when danger occurs, timely alarm, the practice shows that the system has high precision and has certain application value.
