由于地下矿山存在着危险,有必要对无轨车辆进行遥控。遥控车辆可用高软性电缆,也可用无线电信号。在无线电遥控中,司机和车辆之间没有机械连接,司机用一个便携式控制器进行操纵。给定的指令首先被转换为电信号,并用多路调制转换器处理成具有不同脉宽脉冲信号的编码脉冲。这些相应于各给定指令的编码脉冲,经调制器转换成适于无线电控制的信号,然后由高频组件以电磁波的形式发射出去。装在车上的接收机通过天线接收这些电 Because of the dangers of underground mines, it is necessary to remotely control trolley-less vehicles. Remote control vehicles available high-soft cable can also be used radio signals. In radio remote control, there is no mechanical connection between the driver and the vehicle, and the driver operates with a portable controller. The given instruction is first converted to an electrical signal and processed by the multiplexer into encoded pulses with different pulse width pulse signals. These coded pulses, corresponding to each given command, are converted by the modulator into signals suitable for radio control and then emitted by the high frequency components in the form of electromagnetic waves. The receiver mounted on the car receives these electricity through the antenna
