Wireless data acquisition method of optical fiber gyroscope

Abstract

The invention relates to a collecting method for the wireless data of an optic fiber gyroscope. The collecting method includes as follows: firstly a source data processing module collects and clears up the data outputted by the optic fiber gyroscope and then transmits to a RF transmitting module; the RF transmitting module transmits the data which plus the corresponding address and is checked; then a RF receiving module receives a RF signal and intercompares check codes; if correct, the signal is then transmitted to a target data processing module; if wrong, a marking signal is returned back to lead the RF transmitting module to transmit the original data again; finally the target data processing module clears up the data and then transmits the data to a computer; the method realizes the data communication by a non-contact RF method and can directly output the data by a RF mode without the slide ring of a turntable, thus leading the whole data collecting system to be more flexible and solving the problem of frequent errors caused by using the slide ring of the turntable to transmit signals.

Description

technical field [0001] The invention relates to the field of fiber optic gyroscope testing, in particular to a wireless data acquisition method for fiber optic gyroscopes, which is suitable for use in fiber optic gyroscope testing. Background technique [0002] Fiber optic gyroscope is a kind of angular rate sensor, which is widely used in the field of inertial navigation. It is currently the main sensor used to determine the spatial motion attitude of moving bodies, and the turntable is an important device for measuring it. The working environment of the fiber optic gyroscope is very harsh and harsh. In order to simulate the working environment of the gyroscope, each gyroscope prototype must be tested in a harsh test environment. Experiment as a whole. In the general test method, due to the reason of the turntable, the data cannot be transmitted directly through the wire, but the slip ring needs to be used as the carrier connecting the gyro on the turntable and the data ac...

AI Technical Summary

Problems solved by technology

Since the turntable that meets the testing requirements of the fiber optic gyroscope is an expensive test instrument, the purchase of a new turntable will be a relatively large expenditure, so many test units adopt the method of frequent maintenance to improve the reliability of the slip ring, but the slip ring The maintenance of the ring is another difficult and troublesome thing
