PROBLEM TO BE SOLVED: To provide a construction machine control method and a construction machine control system, which have a simple system configuration and simplify an installation operation.SOLUTION: The construction machine control system comprises: a laser surveying instrument 1 for projecting N-shaped beams 8 in rotary irradiation at a constant speed; a construction machine operated within a light reception range of the N-shaped beams 8; and a beam detector for obtaining an elevation angle with respect to the laser surveying instrument 1 on the basis of the light reception of the N-shaped beams 8. The construction machine comprises: a working mechanical unit for carrying out construction operation; a machine control device 13 for controlling the working mechanical unit; and at least three beam detectors disposed at known positions with respect to a reference position of the construction machine. Elevation angles of the beam detectors with respect to the laser surveying instrument 1 are obtained on the basis of light reception results of the beam detectors. The machine control device 13 is configured to control the tilt of the working mechanical unit on the basis of the obtained elevation angles. |
