Problems solved by technology

MEMS gyroscope is the core component of the laser seeker position marker. However, due to the constraints of the processing materials and processing technology level of the MEMS gyroscope itself, it is easily affected by external temperature and torque interference, resulting in a large zero drift error of the gyroscope. Therefore, it is necessary

Abstract

The invention discloses a screening testing system of a laser seeker MEMS gyro. The testing system comprises a testing data acquisition unit, a dynamic screening testing unit and a temperature compensating screening testing unit. The system can perform individual performance screening on the purchased MEMS gyros, thereby preventing discarding processing in a unqualified condition caused by performance screening testing after gyro loading. According to a method of the invention, screening testing can be performed on individual gyros. Through three designed screening testing systems, the MEMS gyro with low zero-bit drift error, stable dynamic performance in different rotating speed environments and stable angular speed output value in different temperature environments can be effectively screened. Through a calibration compensating mode, the precision of the effective MEMS gyros which are screened in different environments can be further improved, thereby improving index precision of a product.

Description

technical field [0001] The present invention relates to the technical field of testing, in particular to a laser seeker MEMS gyroscope (Micro-Electro-Mechanical System, Micro-Electro-Mechanical System, Micro-Electro-Mechanical System, micro-electro-mechanical gyroscope) screening and testing system and method. Background technique [0002] In the seeker of the missile, in order to obtain a stable target image for the photoelectric detector, the platform stabilization system is required to isolate the disturbance of the angular displacement of the missile body to the firing line of the missile, so that the seeker can accurately follow the target line of sight, thus providing a large field of view Target acquisition and tracking and small field of view target recognition provide measurement and calculation benchmarks to improve the hit rate of missiles during travel; the platform stabilization system uses gyroscopes as the core sensitive components, and the measurement accuracy...
