Problems solved by technology

The inertial measurement unit is used to measure many information such as inclination and acceleration in the dynamic state. It has fusion functions such as gyroscope and accelerometer. It is a highly integrated dynamic information measurement device, but its cost is too high and the integration is large. Some functions are not rigid requirements in actual use, and do not reflect the optimal cost performance; installing a rotary angle encoder on the body rotating body requires structural modification of the central rotating body of the excavator, and the installation method is complicated; if the installation positioning is not accurate, The detected encoded signal has a high bit error rate

Abstract

The invention provides a vehicle body rotation angle data processing method and device, a controller and a storage medium, and relates to the technical field of engineering machine. The method comprises the steps: obtaining a first voltage signal and a second voltage signal sent by an angle sensor magnetic induction device, obtaining corresponding first angle data and second angle data according to the linear relation between the voltage signal generated by the magnetic induction device of the angle sensor and the angle; obtaining first rotation angle data and sinusoidal data, and performing data filtering processing on the sinusoidal data to obtain filtered data; and processing the filtering data based on a preset arcsine function to obtain second rotation angle data. According to the method and device, the controller and the storage medium, the rotation angle data of the vehicle body can be rapidly and sensitively measured; the magnetic induction angle sensor is adopted to measure the rotation angle of the vehicle body, installation is convenient, implementation cost investment is small, signal response is sensitive, and mechanical control precision and control comfort can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of engineering machinery, and in particular to a data processing method, device, controller and storage medium for the rotation angle of a car body. Background technique [0002] With the advancement of science and technology, the development of construction machinery has also entered a period of acceleration, especially intelligent excavators with automatic functions and remote control functions play an important role in construction projects. In order to meet the requirements for the use of intelligent excavators, it is necessary to detect the angle of the excavator during the rotation process in real time, and ensure that the whole machine stops according to the predetermined rotation angle to meet the control requirements of the whole machine. In order to complete the precise control of the rotation angle of the excavator, it is necessary to install a rotation angle measuring device on the turnt...
