Method for realizing large-capacity data recording in pod

Abstract

The invention relates to a method for realizing large-capacity data recording in a pod, which is suitable for realizing the large-capacity data recording under a real-time embedded environment of the pod. The method comprises the steps of setting an annular buffer region supported by an operation system; calling a library function to establish an annular buffer region for high-speed data in each route during initializing; inquiring a register state of a high-speed RS422 interface by inquiring and moving each period of a data function in a main working thread, and inputting data into the annular buffer region when a storage register is in a half-full state; periodically inquiring the data situation of the annular buffer region, calling an electronic hard disc writing function in the main working thread when the data meet a 2K state, and writing the data in an electronic hard disc.

Description

technical field [0001] The invention relates to a method for realizing large-capacity data recording in a pod, which is suitable for realizing large-capacity data recording in the real-time embedded environment of the pod. Background technique [0002] Embedded systems are developed with the development of computer technology, microprocessor technology, electronic technology, communication technology, and integrated circuit technology, and are more and more widely used in various occasions, including automobiles, aerospace, aviation, and military equipment. and other fields. At the same time, with the development of technology, the use of flash electronic disks is also relatively extensive. It was only used in general environments before, and it is also used in real-time embedded environments slowly. At present, the aircraft generally uses electronic disks for data recording in special airborne equipment. On the airborne pod, due to the high real-time requirements of the p...

AI Technical Summary

Problems solved by technology

On the airborne pod, due to the high real-time requirements of the pod, if it is necessary to complete its own flight missions and record communication data in real time, when the amount of data is large, it is especially necessary to record both communication data and When recording image data, the original method cannot meet the real-time requirements

Therefore, at present, no large-capacity data recording is performed on other pods
