摘要
应用可编程控制器(PLC)对JM-5型煤气交换机进行改造,使原来对煤气交换机的手动交换改变为自动交换,交换时间任意可调,取消了结构复杂的继电器,使设备的使用寿命、安全性、可靠性都有较大提高。
The application of programmable logic controller （PLC） on the reconstruction of the JM-5 type gas switch, so that the original manual exchange of gas switch change for automatic switching, switching time can be ad- justed arbitrarily, cancelled the complex structure of the relay, so that the service life of equipment, safety, reliabili- ty is greatly improved
