Abstract

A construction machine control system controls a construction machine including a traveling device, a work machine having a working tool, and a swing structure to which the work machine is attached and which is attached to the traveling device to swing with respect to the traveling device. The construction machine control system includes a position detection device that detects a first position which is a position of a partial portion of the construction machine and outputs the first position as first position information; a state detection device that detects and outputs operation information indicating an operation of the construction machine; and a processing device that calculates a second position corresponding to the position of the partial portion using the first position information and the operation information and calculates a position of at least a partial portion of the work machine using second position information.

First claim

The invention claimed is:

1. A construction machine control system that controls a construction machine including a traveling device, a work machine having a working tool, and a swing structure to which the work machine is attached, the swing structure being attached to the traveling device to swing, the system comprising:
a position detection device that detects a first position which is a position of a partial portion of the construction machine and outputs the first position as first position information;
a state detection device that detects and outputs operation information indicating an operation of the construction machine; and
a processing device that calculates a second position corresponding to the position of the partial portion using the first position information and the operation information and calculates a position of at least a partial portion of the work machine using information of the second position.

2. The construction machine control system according to claim 1 , wherein
the processing device calculates the second position using a position of a specific point which is an intersection between an axis of a center of swing of the swing structure and a plane corresponding to a ground surface with which the traveling device makes contact, which is information obtained from the first position and the operation information.

3. The construction machine control system according to claim 2 , wherein
the processing device applies a smoothing process to the position of the specific point and calculates the information of the second position using the position of the specific point obtained after the smoothing process.

4. The construction machine control system according to claim 1 , wherein
the processing device applies a smoothing process to the first position using the operation information to calculate the information of the second position.

5. The construction machine control system according to claim 2 , wherein
the processing device calculates the position of at least a partial portion of the work machine using the information of the second position when the position of the construction machine detected by the position detection device is normal, the travel of the construction machine is stopped, and the swing structure is not swinging.

6. A construction machine control method of controlling a construction machine including a traveling device, a work machine having a working tool, and a swing structure to which the work machine is attached, the swing structure being attached to the traveling device to swing, the method comprising:
calculating a second position of the construction machine corresponding to a position of a partial portion of the construction machine using a first position which is the position of the partial portion of the construction machine detected by a position detection device included in the construction machine and operation information of the construction machine detected by a state detection device included in the construction machine; and
calculating a position of at least a partial portion of the work machine using the second position.
