Abstract (en)
[origin: WO9707296A1] In an excavation region setting apparatus for controlling the region limited excavation by a construction machine, which is adapted to calculate a target speed vector Vc for use in controlling a front unit (1A), on the basis of a vehicle body (1B), restrict when the front unit approaches a boundary of a preset excavation region the moving speed thereof in the direction approaching the same boundary, by correcting the target speed vector, and move the front unit along the mentioned boundary, an outer reference 80 is set first in the horizontal direction in a position outside a hydraulic shovel body, and a depth hr between the outer reference and the boundary of the excavation region is then set by using a setter (7), for the purpose of setting the excavation region. The front unit (1A) is then moved, and, when the position of a front reference 70 agrees with that of the outer reference, an outer reference setting switch (71) is pressed. Consequently, a control unit (9) computes a height hf between a vehicle body reference point <u>O</u> and the outer reference, and then a height hs of a boundary surface of the excavation region with respect to the vehicle body reference point <u>O</u> on the basis of this depth hr by using the height hf as a correction value, and set the excavation region based on the vehicle body (1B), on the basis of which the target speed vector Vc is calculated. This enables the setting of an excavation region suitable for an excavation control operation in which computation is carried out on the basis of the vehicle reference to be done, and a highly reliable control operation to be carried out.
