摘　　要：根据煤矿主要通风机不允许停车的特点,通过研究电动机并网和PLC控制方法,形成主要通风机工变频自动切换技术,给出了相应的软硬件设计思路和方案;最终实现了不停车情况下备用通风机设备自动投入和工变频供电回路自动切换的功能,提高了整个系统的安全可靠性和自动化程度。According to the no parking characteristic of mine main ventilation,through the research of motor contemporaneous grid and PLC control method,the work- frequency automatic switching technology was put forward,and the design idea and scheme of hardware and software was obtained. The function achieved that the standby ventilator equipment ran automatically and work- frequency switched automatically in the case of no parking,which improved the safety reliability and automation degree of the whole system.
