Design Of Laser Gyro Temperature System Based On ARM Cortex-M4

Strapdown inertial navigation system has the advantages of strong concealment,rich navigation information,low power consumption,fast startup time,etc.,and is widely used in navigation,aviation,aerospace and other fields.The laser gyro is the core component of the strapdown inertial navigation system and is used in high-precision angular rate measurement scenarios.Research and application show that the measurement accuracy of laser gyro is easily affected by the temperature and other parameters of its application scene.Therefore,the strapdown inertial navigation system needs to make necessary parameter compensation for the measurement value of laser gyro to improve the accuracy of its sensing output.The thesis mainly discusses the realization of the temperature parameter compensation system of the laser gyroscope based on the ARM Cortex-M4 microprocessor.The corresponding research contents are as follows:(1)Investigated the current research status of laser gyroscope temperature compensation method,and analyzed the source of measurement error and temperature characteristics on the basis of discussing the working principle of laser gyroscope;(2)On the basis of the measured value of the laser gyro,the influence of the ambient temperature on the measured value of the laser gyro is studied;and the corresponding theoretical model is given;(3)Designed a compensation system for the temperature parameters of the laser gyro based on the ARM Cortex-M4 microprocessor,and completed the joint adjustment of the LabVIEW host computer communication and the overall test system in the temperature compensation system,and the joint adjustment test results See,the laser gyro temperature compensation model given in the article is correct,and the temperature compensation system implemented is feasible.The research results in this article have been applied to a certain model of laser gyro products.
