Applicable to universal Buick oil pressure sensor 12621234

Technical introduction

At present, the development speed of intelligent excavators is getting faster and faster. In order to realize intelligent control of excavators, the corresponding rotation angle sensors are basically installed on the working devices, which require high control accuracy, and the calibration error of the sensors directly has a serious impact on the intelligent control level. Because the working devices belong to multi-mechanism connection, they are affected by design tolerance, manufacturing error, accumulated error and inconsistency of errors. In the prior art, it is difficult to calibrate the relative angle between the sensor and the working mechanism, resulting in low calibration accuracy and large error corresponding to the angle of the sensor and the real working posture of the excavator, which reduces the control accuracy of the working posture.

Technical realization idea

The purpose of this patent technology is to at least solve the problem that it is difficult to calibrate the relative angle between the sensor and the working mechanism by the existing calibration method of the excavator sensor, which leads to low calibration accuracy and large error corresponding to the real working posture of the excavator, and reduces the control accuracy of the working posture. The purpose is achieved through the following technical scheme: the first aspect of the patent technology provides a calibration method for excavator sensors, which comprises the following steps: parking the excavator on a horizontal ground, and making a horizontal line parallel to the horizontal ground from the hinge point between the movable arm of the excavator and the platform; According to the horizontal line, and calibrating the boom angle sensor. In the calibration method of excavator sensor according to the patent technology, the excavator is parked on the horizontal ground, and a horizontal line parallel to the horizontal ground is made from the hinge point of the excavator's boom and platform. According to this horizontal line, the hinge point of the excavator's boom and bucket bar is controlled to be on the horizontal line, and the connecting line between the dumpling point of the boom and platform and the dumpling point of the boom and bucket bar can be recognized as being at a horizontal angle.
