煤矿井下机电设备(如采煤机、输送机、局扇、破碎机和提升机等)开停状态需要及时地上传到整个监测系统中,以防有设备损坏及时采取行动避免事故的发生。主要利用电磁感应原理将电气设备的开停状态转换成各种标准信号,通过信号传输线传送给矿井生产监测系统,最终实现井下机电设备开停状态自动监控的功能。 Coal mine mechanical and electrical equipment (such as shearer, conveyor, bureau fan, crusher and hoist, etc.) open and stop the state needs to be timely uploaded to the entire monitoring system to prevent equipment damage in time to take actions to prevent accidents. Mainly using the principle of electromagnetic induction to open and close the electrical equipment state into a variety of standard signals transmitted through the signal transmission line to the mine production monitoring system, and ultimately to achieve mechanical and electrical equipment downtime automatic monitoring function.
