专利汇可以提供Method and apparatus for controlling performance of bulldozer专利检索,专利查询,专利分析的服务。并且PURPOSE: To raise the accuracy of finishing by a method in which three- dimensional positions of a tructor in relation to an optical reference face formed by two projectors on the ground station side are detected on the tructor to obtain performance in the present working section on the basis of the detected value.
CONSTITUTION: When projectors 1 and 2 are turned, laser beams from the projectors 1 and 2 are received by a reference light receiver 3, and the turning period is measured by the ground monitor 16 and stored in a position measuring controller 9. After the laser beams from the projectors 1 and 2 are received by the receiver 3, the time until received by the light receiver 5 of the bulldozer B is stored in the controller 9. The angle and coordinate of the receiver 5 are calculated by the controller 9 from the distance L between the projectors 1 and 2, the angle between the projectors 1 and 2 and the receiver 3, and the said time. Data on the planar position of the bulldozer B in relation to the projectors 1 and 2 and optical reference face are calculated and performance data at each point in the grading section are obtained by conversional calculation.
