Abstract

The invention discloses a gyroscope sensor calibrating device which comprises a CAN (Controller Area Network) bus, a fixing table, a calibration circuit board, a rotating bracket capable of fixing a plurality of sensor plates, motors for driving the rotating bracket to rotate and a man-machine interaction display board, wherein the fixing table consists of a bottom plate and side plates which are symmetrically arranged on two sides of the bottom plate; the calibration circuit board is arranged on the bottom plate; two ends of a rotating shaft of the rotating bracket are respectively installed on the side plates on two sides of the bottom plate; sensor slot devices through which the sensor plates are supplied with power and communicate with other components are arranged on the rotating bracket; the sensor slot devices are connected with the CAN bus; the motors are installed on the side surfaces of the side plates and are connected with the rotating shaft of the rotating bracket; photoelectric limiting switches for controlling the motors to operate and detecting the position of the rotating bracket are further arranged on the side plates; and both the calibration circuit board and the man-machine interaction display plate are connected with the CAN bus. The invention also discloses a calibrating method of a gyroscope sensor.

Description

technical field [0001] The invention relates to a gyroscope sensor calibration device and a calibration method. Background technique [0002] The gyro sensors in the prior art all have the problem of temperature drift, which brings great inconvenience to some enterprises that require intelligent instruments and equipment with high dynamic performance. Although some high-priced gyro sensors have reduced temperature drift compared with cheaper gyro sensors, they have increased the economic burden on enterprises. In view of this, calibrating gyroscope sensors has become a way for many enterprises to reduce costs. However, the devices for calibrating gyroscope sensors in the prior art have relatively low calibration efficiency and cannot batch calibrate gyroscope sensors. The angular velocity and acceleration are calibrated, and most of the processes still require manual operation. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present i...
