Abstract:
The invention provides a control system for a construction machine comprising: a laser surveying instrument, a construction machine and a direction detecting unit, wherein the construction machine has a working mechanical unit, a machine control device, a machine communication unit, two beam detectors and at least one target and a tilt sensor, wherein the laser surveying instrument has a laser rotary projecting device for projecting a laser beam in rotary irradiation, an electronic distance measuring instrument and a surveying communication unit, wherein each of the beam detectors transmits a photodetection result to the laser surveying instrument or the machine control device, wherein the laser surveying instrument or the machine control device calculates a left-right tilting of the construction machine based on the photodetection result and a distance measurement result of the target, and the machine control device controls an operation of the construction machine based on a detection result of the direction detecting unit, a front-rear tilting by the tilt sensor, a distance measurement result of the target and the left-right tilting.
