DEVICE TO CONTROL CONSTRUCTION MACHINE (VERSIONS) Russian patent published in 2010 - IPC B66C13/18 E04G21/04 B25J9/16 

FIELD: transport.

SUBSTANCE: invention relates to construction machinery. Proposed device comprises control board arranged on the machine or made self-contained, transducers of spatial position of boom and/or its sections, and/or machine rotary platform. It comprises also electronic control unit to receive and process signals from transducers and control board, set up and memorise system of coordinates and generate signals for operator and/or those to control machine drives, and display. Display serves to show data coming from electronic unit and/or control board. Electronic control unit decomposes instructions from control board into control signals for boom and/or its sections, and/or machine rotary platform so that control element displacement along one main direction corresponds to boom travel along one axis of set coordinate system. In compliance with 1^st version, display, electronic control unit and/or control board can display coordinate system on display furnished with sensor screen, while electronic control unit and display can set up coordinate system using signals generated by sensor screen by operator actions. In compliance with 2^nd version, proposed device additionally comprises gripper vertical position transducer, while electronic control unit receives and processes signals from said transducer, and generates gripper actuator control signals.

EFFECT: higher efficiency and accuracy of control.
