Problems solved by technology
In particular, depending on the orientation of the boom, arm, bucket, and upper body, the working equipment may interfere with the upper or lower body of the excavator, and there is a possibility of damage to the working equipment or the excavator if they interfere.
[0003] On the other hand, it takes quite a long time for operators to adapt to the newly installed working equipment
In addition, even if the operator is newly familiar with the working device, if he relaxes a little, the collision of the working device may occur, so it is necessary to adjust the construction machine very carefully.

The invention relates to an apparatus and a method for collision prevention control of a front device of construction machinery. The control apparatus comprises a storage part (20), a comparison part (10) and an output part (40). The storage part stores shape and size information of a construction machinery main body. The comparison part receives the shape and size information stored in the storage part and position information of the front device moved according to operation by an operating device, and determines whether the position information is close to the shape and size information. When the comparison part determines that the front device moves into a collision distance with the construction machinery main body, the output part generates a control signal restricting actions of the front device so that the front device does not collide with the main body.
Description
technical field [0001] The present invention relates to an anti-collision control device and a control method for a front device of a construction machine. The attitude of the excavator is an anti-collision control device and control method for the front device of the construction machine to prevent the operation device from colliding with other structures of the excavator. Background technique [0002] Generally speaking, working devices of construction machines have different external sizes and shapes, and such working devices may exist at positions beyond the driver's field of vision during excavator work. In particular, depending on the orientation of the boom, arm, bucket, and upper body, the working equipment may interfere with the upper or lower body of the excavator, and there is a possibility of damage to the working equipment or the excavator if they interfere. . [0003] On the other hand, it takes quite a long time for the operator to adapt to the newly install...
