ABSTRACT:
The present invention provides a construction equipment control system, comprising a rotary laser irradiating system for forming a laser beam reference plane by the laser beam and capable to tilt the laser beam reference plane, a level sensor installed on a ground leveling tool of construction equipment and for performing photodetection of the laser beam to give instruction on a height of the ground leveling tool, a GPS receiving system for detecting a position of the construction equipment, and a control device for controlling a gradient of the laser beam reference plane formed by the rotary laser irradiating system based on the detection result of the position of the construction equipment by the GPS receiving system, whereby ground leveling operation for a horizontal surface, an inclined surface and a curved surface can be performed by measuring the position of the construction equipment at real time and by controlling the height of the ground leveling tool based on working data.
