In order to ensure the safety of workers when the underground scraper enters into the mining room,and con-sidering the complicated underground mining environment,a wireless remote control system was designed.This system mainly consists of remote controller and vehicle on board controller.Both of remote controller and vehicle on board controller are based on ARM processor.The remote controller will convert the operator′s operations into control command.In accordance with a cer-tain communication protocol,the control command is wirelessly transferred out.Vehicle mounted controller has two modes of operations,remote control and local control.In the remote control mode,vehicle on board controller receives the control com-mand transferred by the remote controller,and works;In the local control mode,vehicle on board controller receives commands from the on-board control handle and buttons,and works.The remote control mode can make the operator away from the danger-ous environment with the safety improved;The local control mode allows the operator to work in the scraper with great flexibil-ity.This system has the characteristics of low investment and quick response,and it is very suitable for complicated and changeable underground mining operations.%为了保证井下铲运机进入矿房时的作业人员安全,并且考虑到地下采矿环境复杂多变,特此设计了一种无线遥控系统.该遥控系统主要由遥控器、车载控制器构成.遥控器及车载控制器均以ARM处理器为控制核心.遥控器将作业人员的操作转换成控制指令,按照一定的通信协议,以无线的形式将控制指令发送出去.车载控制器具有遥控和本地控制2种工作模式.车载控制器工作在遥控模式时,接收遥控器发出的控制指令,并依此作业;车载控制器工作在本地控制模式时,接收车载控制手柄及按钮的命令进行作业.遥控模式可以使得作业人员远离危险环境,提高了安全性;本地控制模式可使得作业人员在铲运机上作业,兼具了灵活性.该系统具有投资小、见效快的特点,非常适合复杂多变的井下采矿作业.
