ABSTRACT:
An apparatus for and a method of remote controlling an operation of a vibration roller, capable of achieving the operation of vibration roller under a condition that no operator have a ride in the vibration roller. The apparatus includes a wireless transmitting unit, a wireless receiving unit, a control unit for controlling functional parts required for the operation of vibration roller, an operation switch unit, a forward/rearward running manipulating unit, a steering unit and an acceleration and stop manipulating unit. The method includes the steps of analyzing operation command data, when the analyzed data is command data for ON/OFF of a particular switch of the operation switching unit, switching on or off the switch, when the analyzed data is data about an operation of the forward/rearward running manipulating unit, applying a drive voltage to the forward/rearward running manipulating unit for rotating a motor for a forward/rearward running lever, when the analyzed data is data about an operation of the steering unit, applying a drive voltage to the steering unit for rotating a motor for a steering handle shaft, and when the analyzed data is data about an operation of the acceleration and stop manipulating unit, applying a drive voltage to the acceleration and stop manipulating unit for rotating a motor for an acceleration knob and a stop knob.
