A kind of audio and video storage method for embedded device mechanical hard disk

Abstract

The invention discloses an audio and video storage method for a mechanical hard disk of an embedded device. The audio and video storage method for a mechanical hard disk of an embedded device includes a hard disk data writing process, and the hard disk data writing process includes the following steps: a processing module checks a local Whether there is audio and video cache data; if there is audio and video cache data, read the frame data, if you need to switch partitions, switch partitions; if you do not need to switch partitions, continue to store audio and video files in the current partition; if writing audio and video files If there is an error in the file, the bad partition will be marked, the partition will be switched, and the hard disk will give an alarm; if the audio and video files are correct, step S1 will be performed to write the next file. To sum up, the beneficial effects of the present invention are as follows: the present invention uses multi-channel data to be written into one file in a centralized manner, and can be continuously written in the hard disk without causing the head to jump back and forth, which can ensure high data speed. Write to extend disk life.

Description

technical field [0001] The invention relates to an audio and video storage method for a mechanical hard disk of an embedded device. Background technique [0002] The traditional technology of storing audio and video to a mechanical hard disk is to simply create files, read and write files, and delete files. When the amount of audio and video data is relatively small, it can meet the general file storage and reading requirements; The clearer it is, the larger the hard disk space occupied for storing data, the longer the data continues to be written, and the more the number of files. Therefore, the creation and deletion of disk files are more and more frequent. Increase the hard disk startup and hibernation operations, increase the number of head calls and resets, and increase a large number of disk fragments. The increase in power consumption will also generate a lot of heat, which will adversely affect the life of the hard disk. At present, most real-time storage devices for...

[0002] The traditional audio and video storage to mechanical hard disk technology is simply to create files, read and write files, and delete files. When the amount of audio and video data is relatively small, it can meet the general file storage and reading requirements; The clearer it is, the larger the hard disk space occupied by stored data, the longer and longer the continuous writing time of data, and the increasing number of files. Therefore, operations such as creation and deletion of disk files are becoming more and more frequent. Increase hard disk start-up and sleep operations, increase the number of head calls and resets, increase a large number of disk fragments, and increase power consumption will also generate a lot of heat, which will adversely affect the life of the hard disk. At present, most real-time storage devices for audio and video data are Using a mechanical hard disk, it is imperative to manage the hard disk storage and improve the life of the hard disk
