REMOTE CONTROL SYSTEM FOR CONSTRUCTION EQUIPMENT AND REMOTE CONTROL METHOD THEROF

摘要

PURPOSE: A remote control system of construction machinery and a controlling method thereof are provided to safely and easily control construction machinery by enabling an operator in a remote site to drive construction machinery. CONSTITUTION: A remote control method of construction machinery comprises following steps. A rotary angel around a horizontal shaft of an operator's lower arm, an angle between the upper arm(UA) and the lower arm(LA), and a bending angle of an operator hand, and a rotary angel around a vertical shaft are sensed. Whether the sensed rotary angles belong to a standard angle range or not is determined. In case the rotary angle exceeds the standard angle range, information about the rotary angle is transmitted to an equipment controller to drive a boom, an arm, a bucket, and an upper rotating body(20).
