Construction machine control system
First Claim
1. A construction machine control system, comprising a working tool, a working arm for supporting said working tool and for operating said working tool as required, a machine body for supporting said working arm and for being rotatable, a rotating direction acquiring unit provided on said machine body, a control unit having a storage unit and a display unit, wherein said working arm is configured by two or more links with length already known respectively which are connected in a bendable manner, wherein there are further provided a two-axis tilt sensor on said machine body for detecting a horizontal position, a working arm tilt sensor for detecting a tilting of each links of said working arm, and a working tool tilt sensor for detecting a tilting of said working tool, wherein said control unit displays a guidance screen on said display unit based on a working data stored in said storage unit and where a working position and a design gradient are set, based on a direction of said machine body acquired from said rotating direction acquiring unit, and based on detection results of said two-axis tilt sensor, said working arm tilt sensor and said working tool tilt sensor, and said guidance screen displays a guiding information for guiding said working tool to the working position, wherein a working position mark and a bucket mark having predetermined shapes are displayed on said guidance screen as guiding information, a condition of said working tool with respect to the working position is indicated depending on a change of the shape of said bucket mark and on a difference of position with respect to said working position mark, and said working tool is guided to the working position so that the shape and the position of said working position mark and said bucket mark coincide with each other.
