西门子LOGO!在煤矿断电控制器中的应用

Application of Siemens LOGO! in Coal Mine Switching-out Controller

煤矿断电控制器是井下安全生产监控环节中的重要设备,可用于瓦斯超限时的自动断电、通风局扇故障时风电闭锁及自动启动备用局扇等。为进一步提高断电控制器的安全、可靠性,引入了西门子可编程逻辑控制器LOGO!,实现了井下相关监测设备及工作设备间的复杂逻辑关系控制,产品经实际使用,效果良好。

The coal mine switching-out controller is the important equipment in coal mine＇s safe production monitoring link, which can be used for power switching-out automatically when gas exceeds the specified limit value, latching automatically when ventilator local fan occurs fault, and starting the stand-by local fan automatically etc.. To upgrade safety and reliability of the coal mine switching-out controller,the Siemens programmable logic controller LOGO! was introduced, then the complicated logic relation control between monitoring equipment and working equipment of coal mine was realized. The actual applications get better results.
