Information processing method and device for optical fiber heading and attitude system, facility and storage medium

Abstract

The invention provides an information processing method and an information processing device for an optical fiber heading and attitude system, a facility and a storage medium. A first time mark is adopted to mark a first memory, a second time mark is adopted to mark a second memory, if the first time mark is set to be greater than the second time mark, the first memory records current system information; if the first memory is saturated, the first time mark is transmitted to the second time mark, and the second memory records the current system information; the system information of the firstmemory is backed up to a third memory; the system information of the first memory is erased; if the second memory is saturated, the second time mark is transmitted to the first time mark, the first memory records the current system information, and the system information of the second memory is backed up to the third memory; and the system information of the second memory is erased. According to the method, the built-in self-inspection of the optical fiber strapdown heading and attitude system is realized, the information is stored in real time, and the testability, maintainability and fault diagnosis capability of the product are improved.

Description

technical field [0001] The present application relates to the field of fiber optic attitude system, and in particular to an information processing method, device, equipment and storage medium of the fiber optic attitude system. Background technique [0002] As the main attitude information source of the aircraft, the fiber-optic attitude system provides information such as the heading, pitch and tilt angle of the aircraft. [0003] In the existing technology, it is required that the product can pass the power-on self-inspection and periodic self-inspection, and comprehensively perform fault detection based on the normal working range and practical significance of physical parameters, and at the same time, the detected fault time and fault code can be stored in a non-volatile manner. The original product has no fault parameter function; [0004] If a fault is reported during the flight of the product, the after-sales personnel will judge and locate the fault based on the pil...

AI Technical Summary

Problems solved by technology

[0004] If a fault is reported during the flight of the product, the after-sales personnel will judge and locate the fault based on the pilot's description. The artificial description of the fault will result in inaccurate information provided, which will affect the accuracy of problem solving.

When the product reports a failure in a specific state, the probability of failure recurrence is small, and it is difficult to accurately and quickly determine the cause of the failure, resulting in poor testability of the product
