Abstract

The embodiment of the invention provides a RapidIO-based flight parameter data storage structure and a storage method, the RapidIO-based flight parameter data storage structure specifically comprisesa data management processor and a data loading recorder, and the data management processor communicates with the data loading recorder through a RapidIO high-speed bus. And a task processing module PPC is arranged in the data management processor, the task processing module PPC is used for acquiring the data of the acquisition board, and the task processing module PPC acquires a task machine instruction through the FC node card. A plurality of different RapidIO windows are created in the task processing module PPC, and the RapidIO windows are used for distinguishing task machine instructions and acquisition board data. And the data loading recorder creates RapidIO mapping windows corresponding to the RapidIO windows according to the mapping addresses of the RapidIO windows. Through the processing scheme disclosed by the invention, the high reliability and real-time performance of flight parameter data recording are greatly improved.

Description

technical field [0001] The present disclosure belongs to the field of electronic technology, relates to data storage technology of avionics, and in particular relates to a storage structure and storage method of flight parameter data based on RapidIO. Background technique [0002] With the rapid development of aviation equipment technology, especially in the context of the adjustment of military strategy and changes in the combat use of aviation equipment, the requirements for aircraft ground support are getting higher and higher, and monitoring the health indicators of flying ginseng is the most fundamental among them. factor. After the flight parameter data is collected, it needs to be stored, and then the field maintenance personnel of the maintenance department can conduct a comprehensive analysis on it. [0003] At present, the recording of flight parameter data is usually carried out through Ethernet. For different data types, it is realized by creating different sock...
