Vehicle-mounted DVR (Digital Video Record) raw disk file storage system

Abstract

The invention discloses a vehicle-mounted DVR (Digital Video Record) raw disk file storage system, which is applied to DVR video big data storage. The system comprises a disk, an equipment side and a player, wherein the equipment side and the player are connected with the disk; the equipment side is also used for writing data; and the player is used for reading the data. The disk is divided into two partitions, wherein one partition is a data index partition of the first partition, the other partition is a data storage partition of the second partition, and the ratio of the data index partition to the data storage parathion is about 1:500. Since the data index partition of the second partition does not need to carry out the recording work of any file system, the a writing speed is high, the data index partition of the second partition does not need to be formatted and does not need to carry out system detection work, all file system formatting, system detection and file system repair happen in an ultra-small partition, i.e., the data index partition of the first partition, workload is greatly reduced even if a behavior style is the same, all pieces of work can be finished within 30 seconds, a flying feeling is brought for users during daily startup and routine examination and repair, and the system has the advantages of being high in running speed, smooth in use and convenient in operation.

Description

technical field [0001] The invention relates to the technical field applied to DVR video big data storage, in particular to a vehicle-mounted DVR bare disk storage file system. Background technique [0002] In order to solve the problem of large data storage of DVR videos, most manufacturers currently adopt the strategy of pre-allocating disks, that is, formatting the entire disk into fat32 format, and most of the file systems are pre-allocated using fat32 disks The resulting problems are quite obvious, including the following problems: the disk formatting time is too long, the file system detection and repair time is too long when starting up, and the writing efficiency is also very low , 32G capacity disk, the file system detection and repair time of the fat file system will take 2-10 minutes to complete, and file fragments are likely to occur during the operation. Therefore, in order to solve these problems, the applicant has developed a method to divide the disk into tw...
