Problems solved by technology
The current QAR decoding software usually adopts a stand-alone decoding method, which supports a small amount of data. When the amount of data is too large, the decoding speed is too slow; and does not support distributed computing, the decoding efficiency is low, and the use cost is high. Support horizontal expansion, unable to adapt to the growing mass of raw data

Embodiment Construction
[0049] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0050] Considering that the current QAR decoding software usually adopts a stand-alone decoding method, the amount of data supported is small, when the amount of data is too large, the decoding speed is too slow; and it does not support distributed computing, the decoding efficiency is low, and the use cost is high , Does not support horizontal expansion, and cannot adapt to the ever-increasing mass of original data. Therefore, the present invention proposes a solution.
[0051] Specifically, the present invention proposes a QAR data decoding method, system, and storage medium based on distributed computing. The main solution of the present invention is based on big data distributed computing technology, by building a flexible and easy to expand big data platform to store aircraft The massive QAR raw data generated d...

The invention discloses a QAR data decoding method and system based on distributed calculation and a storage medium. The method comprises the steps: building a big data decoding platform based on a plurality of server nodes, and migrating QAR data to the big data decoding platform; reading the QAR data of the big data decoding platform by adopting a distributed calculation engine, and performing data analysis on the QAR data of the big data decoding platform by adopting a distributed calculation method; querying a preset data frame configuration list to obtain a data frame configuration to which each parsed file belongs; dividing the data frame configuration to which each analyzed file belongs into layers according to the frame length formulated by the preset data frame configuration, anddividing a corresponding sub-frame in a preset manner; and traversing the data of each subframe, and calculating a corresponding decoding engineering value according to a preset decoding rule. Compared with the prior art, the decoding speed and efficiency of the QAR data are improved.
Description
Technical field [0001] The present invention relates to the field of big data technology, in particular to a QAR data decoding method, system and storage medium based on distributed computing. Background technique [0002] Data is given the background, which is information; the law is refined, which is knowledge; and after systematic analysis, it becomes the production factor and management tool, and the data is the resource. Exploring solutions based on "big data" is an important means of management upgrade, benefit upgrade, and efficiency upgrade. The influence of the "big data" era on the aviation operation business system is self-evident. It is under this background that how to tap the potential of QAR (Quick Access Recorder) has become a new topic for many airlines. The current QAR decoding software usually adopts a stand-alone decoding method, which supports a small amount of data. When the amount of data is too large, the decoding speed is too slow; and does not support ...
