Description

technical field [0001] The invention relates to an optical fiber gyroscope wireless network acquisition system and an acquisition method thereof, belonging to the field of optical fiber gyroscope testing. Background technique [0002] Optical fiber gyroscope is a kind of angular velocity sensor, which has the characteristics of high precision, fast response speed, and has nothing to do with the acceleration of gravity. It is widely used in aviation, navigation, and national defense industries. Compared with the commonly used mechanical gyroscope, it has the advantages of small size, light weight, and no mechanical transmission part. [0003] Before a fiber optic gyroscope leaves the factory, its performance needs to be collected in various aspects. During the calibration process, it also needs to be combined with the turntable to collect the data of the gyroscope while the turntable is rotating. The traditional acquisition method is to use multiple slip rings on the turntab...

AI Technical Summary

Problems solved by technology

After long-term collection, the turntable is not stable enough and requires manual maintenance, which restricts the collection process

The wireless acquisition method realized by Bluetooth and other technologies has a low rate. Although it can meet the data transmission requirements of some fiber optic gyroscopes, the bit error rate often does not meet the requirements. If further data verification processing and data retransmission in case of errors are performed, The wireless rate must be much higher than the rate requirement of the gyro

Similarly, this acquisition method is not reliable and cannot meet the requirements of reliable data transmission in bad weather or complex electromagnetic environments

Regarding efficiency issues, traditional wireless acquisition methods often only support end-to-end single-point acquisition, which is not conducive to the unified management of multiple devices under test. The acquisition process is time-consuming, resulting in low efficiency, which is not conducive to large-scale production and acquisition of fiber optic gyroscopes
