Abstract: In order to ensure the safety of workers when the underground scraper enters into the mining room,and considering 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 certain 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 command 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 dangerous environment with the safety improved;The local control mode allows the operator to work in the scraper with great flexibility.This system has the characteristics of low investment and quick response,and it is very suitable for complicated and changeable underground mining operations.
