Automatic control system for construction machinery |
摘要 |
An automatic control system for a construction machine includes the construction machine provided with a ground leveling implement, a target, and a laser sensor; a survey unit that has a coordinate position measuring element and projects a beam of tracking light indicating a finished-plane height toward the target; a storage unit for storing finished-plane height data in correspondence with a horizontal coordinate position in the coordinate position; a computation unit for computing the finished-plane height data; a modulation unit for modulating the laser beam, based on construction information at the horizontal coordinate position, and for transmitting the construction information to the laser sensor; and a demodulation unit fox demodulating the construction information, based on the laser beam received by the laser sensor. The survey unit is equipped with a finished-height data drive mode in which the laser beam is rotated in a vertical direction by a rotation unit so that the height of the laser beam at the horizontal coordinate position becomes a height from the determined finished plane. The construction machine is provided with a control unit for controlling the ground leveling implement so that it reaches the finished-plane height, based on a position at which the laser beam is received on the laser sensor, and also controlling the ground leveling implement, based on the demodulated construction information.
