Patent Searching and Data


Title:
建設作業機械の自動コントロールシステム
Document Type and Number:
Japanese Patent JP4087515
Kind Code:
B2
Abstract:
An automatic control system comprises a construction machine provided on a construction site and equipped with a ground leveling implement and a target; a survey unit for projecting a beam of tracking light toward the target and receiving reflected tracking light from the target to determine a coordinate position of the target; a storage unit for storing finished-plane height data corresponding to coordinate positions; a computation unit for determining a finished target height at the coordinate position of the target and for computing a deviation between the finished target height and a measured target height; and a transmitter for transmitting the deviation toward the construction site. The survey unit operates in a finished-height data drive mode in which the tracking light is moved vertically so that the height of the tracking light at the horizontal coordinate position is at the finished target height. The construction machine has a receiver for receiving the deviation and a height control unit for controlling a height of the ground leveling implement according to the received deviation data.
