The invention discloses a rotation angle detection device of a turntable of an engineering vehicle, comprising an angle measurement unit, a control unit, and a zero point detector unit; the angle measurement unit is used to detect the rotation angle of the turntable and send it to the control unit ; The zero point detector unit determines the zero point induction signal to the zero point of the turntable rotation angle, and sends it to the control unit; signal and the reading value of the angle measuring unit obtained at this time to obtain the zero point offset; according to the zero point offset, the control unit converts the measured value output by the angle measuring unit into a specific position on the turntable as the zero point The angle measurement value relative to the coordinate system, and the control process is performed based on the angle measurement value. The angle signal obtained by the rotation angle detection device provided by the invention is very intuitive, and can be conveniently used in occasions such as anti-rollover control and the like.
Description
technical field [0001] The invention relates to a position detection technology of a turntable of an engineering vehicle, in particular to a detection device for a rotation angle of a turntable of an engineering vehicle. The present invention also provides an engineering vehicle using the above device. Background technique [0002] Various turntables are designed in many construction vehicles to provide slewing functions for actuators that require multi-directional operations. The most common actuator that requires slewing is the working arm. For example, construction vehicles such as construction cranes, concrete pump trucks, and fire trucks all have working arms that can be retracted or folded, and these working arms need to be rotated to realize the basic operation actions of these construction vehicles. For example, hoisting objects or people from one location to another, as well as concrete pouring operations, all-round lifting operations of cranes, etc. The way to r...
