载波遥控在矿山设备中经常出现。它是将控制信号经电力电缆由控制室传递到被控设备从而实现遥控的。这种遥控方法既可以避免单独敷设遥控信号线路，又能解决无线电波被吸收问题，因此在矿井下非常优越。即使在地面上，载波遥控也是非常适用的，例如路灯、电铃等的遥控。常用的?
Carrier remote control often appear in mining equipment. It is the control signal through the power cable from the control room to the controlled device in order to achieve remote control. This remote control method can not only separate the remote control signal lines, but also solve the radio wave absorption problem, so it is superior in the mine. Even on the ground, carrier remote control is also very applicable, such as street lights, bells and other remote control. common?
