Abstract

The embodiment of the invention discloses a sensor temperature compensation method, device and equipment and a storage medium. The method comprises steps of firstly, collecting the temperature, a first sine value and a first cosine value of a magnetoresistance effect sensor system; determining a first angle according to the temperature, the first sine value and the first cosine value; determiningcompensation data according to the temperature, the first angle and a preset compensation table, the compensation table comprising a second sine value and a second cosine value corresponding to different preset angles of the magnetoresistance effect sensor system at each preset temperature and each preset temperature; and finally determining a second angle based on the compensation data, the firstsine value and the first cosine value. The problem that the measurement result of the angle sensor is inaccurate in the current technical scheme is solved, and the accuracy of the measurement resultis improved.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a sensor temperature compensation method, device, equipment and storage medium. Background technique [0002] Angle sensor refers to a device that can sense the measured angle and convert it into a usable output signal. It is especially important in today's digital era. [0003] The magnetoresistance effect sensor system detects the direction of the magnetic field by measuring the sine and cosine components, so as to realize the measurement of the angle. However, the magnetoresistance effect sensor system includes a magnet and a mechanical structure that rotates the magnet. After actual measurement, when the temperature changes, because the magnetic field of the magnet also changes with the temperature change, the measured angle will shift. , making the measurement results inaccurate. [0004] Therefore, in the existing technical solutions, there is a problem of inaccurate meas...
