Testing system and method for automatically evaluating performance of laser gyroscopes

Abstract

The invention relates to a testing system and method for automatically evaluating performance of laser gyroscopes. The system is technically characterized by comprising the laser gyroscopes, a sensitive amount signal collecting controller, an upper computer and a UPS. The sensitive amount signal collecting controller comprises a machine case and a collecting control circuit in the machine case. The collecting control circuit comprises a collecting control board, an AC/DC module and a DC/DC module. The testing system can automatically judge the starting and ending time of a test, automatically start and end the test, and conduct repeated testing; after each test ends, the performance indexes of the gyroscopes are automatically calculated and saved; the testing method is more standard and easier to operate, test cost is saved, and test operability and reliability are improved.

Description

technical field [0001] The invention belongs to the technical field of laser gyroscope testing, in particular to a testing system and a testing method for automatically evaluating the performance of a laser gyroscope. Background technique [0002] The inertial navigation system using the laser gyroscope needs to go through temperature compensation and calibration before it can be put into the test. Replace the gyroscope. After replacing any gyroscope, the inertial navigation system needs to be warmed up and calibrated again until it meets the requirements of the inertial navigation system. This process seriously affects the smooth progress of scientific research and production. Therefore, it is necessary to conduct a comprehensive accuracy assessment of the gyroscope before installing the inertial navigation system, so that the inertial navigation system can select gyroscopes in a targeted manner and improve work efficiency. The traditional gyroscope performance evaluation...
