Abstract

The invention discloses a gyroscope and accelerometer batch calibration device which is in communication connection with a CAN (control area network) bus and a man-machine interaction display panel. The calibration device comprises a base frame, a motor supporting plate vertically arranged on the base frame, and a bracket, wherein a motor is arranged on the motor supporting plate; a rotary frame driven by the motor to rotate is hinged on the bracket; slide grooves are formed in two sides of the rotary frame; calibration flat plates are connected to the slide grooves in an inserted manner; positioning devices for positioning sensor plates are arranged on the calibration flat plates; a limit switch for controlling the rotary angle of the rotary frame is arranged on the bracket. According to the gyroscope and the accelerometer batch calibration device, the sensor plates can be calibrated in batches in one time, so that the calibration efficiency is improved. The invention further discloses a gyroscope and accelerometer batch calibration method.

Description

technical field [0001] The invention relates to a batch calibration device and method for gyroscopes and accelerometers. Background technique [0002] Gyroscopes and accelerometers are commonly used in inertial navigation systems. Gyroscopes are commonly used in inertial navigation systems and are mainly used to measure angular velocity; accelerometers are another important member of inertial navigation systems and are mainly used to measure the direction of gravitational acceleration. In general, the data step sheet is given a fixed coefficient. For different temperatures, this coefficient will appear "temperature drift". In order to ensure that the inertial navigation system is not affected by temperature, it is necessary to make a device to correct the coefficient within the specified temperature range. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a batch calibration device and method for gyr...
