Data storage method of data recorder, data storage module and data recorder

Abstract

The invention relates to a data storage method of a data recorder, a data storage module and the data recorder, and the data storage method of the data recorder comprises the following steps: S1, dividing a Flash area into a first area and a second area; s2, searching a last end mark in the first area and continuing writing by taking the last end mark as a starting point; s3, receiving a start record instruction, and judging whether the start record instruction is valid or not; if the record starting instruction is valid, sequentially executing the following steps: S31, recording in a second area, and starting to store data from an initial position of the second area; and S41, judging whether the data in the second area is fully stored or not, stopping recording in the second area when the data in the second area is fully stored, and otherwise, returning to the step S31. According to the data storage method of the data recorder, data are continuously written into the first area when the instruction is invalid, and effective data in the second area can be prevented from being lost.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a data storage method of a data recorder, a data storage module and a data recorder. Background technique [0002] The modern environment is complex, and it is particularly important to have a large amount of data on real target characteristics, interference and environmental characteristics. With the advantages of large storage capacity, fast storage speed, strong anti-interference ability, no limitation of flight range, and high reliability of data recovery, the data recorder makes up for the shortcomings of the traditional radio telemetry system and becomes the best choice for flight parameter storage in the flight test process. key equipment. [0003] The data recorder is generally composed of a power management module, a signal conditioning module, an acquisition control module, and a data storage module. The data storage module is used as the final storage location fo...
