Description
Technical field
The present invention relates to a kind of methods for promoting DVR file writing speed, belong to DVR field of data storage.
Background technique
Against the background of the prior art, when executing standard FAT file system operation, when recording two videos and there are it simultaneously
When his file write-in work, a large amount of fragmentation files are easy to produce, so that system is slack-off.What is now used in the market includes following solution
Certainly scheme is written in different storage equipment one is being identified using multiple storage devices to different types of file, this
Kind solution is made that certain improvement to file fragmentation, but causes file writing speed slack-off；The second is first by DVR video
File is first stored in internal storage as transition, is periodically classified again and is transferred to External memory equipment, such solution one
Determine the alleviation that can guarantee file fragmentation in degree, but not can guarantee the continuity of file storage.
Summary of the invention
In view of the deficiencies of the prior art, used the present invention provides a kind of method for promoting DVR file writing speed
The technical scheme comprises the following steps:
Simultaneously identification information is written in designated position in S100, formatted storage equipment；
S200, it is creatied directory area in data start with DVR bibliographic structure；
S300, setting directory area, video area and reserved area memory space；
S400, file configuration table is written into system；
S500, the identification information built in based on storage equipment, determine the property of storage equipment, according to judgement result
Execute corresponding operating；
S600, whether it is that video file determines to storage file, corresponding operating is executed according to judgement result；
S700, the write state of proactive and/or rear camera file is determined, is accordingly grasped according to determining that result executes
Make；
S800, whether lock operation is needed to determine file, corresponding operating is executed according to judgement result.
Further, identification information described in step S100 and step S500 includes original equipment manufacturer and device type
Information.
Further, DVR bibliographic structure described in step S200 refers specifically under file configuration table system protocol rule, will
The data separation for storing equipment is directory area, video area and reserved area；Wherein video area includes proactive video file
Region and rear camera file area；Further, proactive and rear camera file area respectively includes ordinary video region and lock
Determine video area.
Further, the memory space distributed in step S300 is as unit of sector.
Further, it is DVR storage card to the judgement result of storage device properties in step S500, then enters S600 step and hold
Row next step；If it is determined that result is common memory card, then illustrates that write storage device is conventional equipment, execute normal file and match
Set table write operation.
Further, it is video file to the storage file property determination of write-in DVR storage card in step S600, then enters
S700 step performs the next step suddenly；If not video file, then execute normal write operation, and it is stored in the reserved of storage equipment
In region.
Further, the write state of proactive and/or rear camera file is determined in step S700, if it is determined that result
In write state, then to be further determined to the path that file is written into, if it is determined that result is at the path being written into
In locking path, then be directed toward the sector of next file, if it is determined that result be it is no, then be directed toward next sector；If to file
It is not write state that write state, which determines that result is, then enters S800 step and perform the next step suddenly.
Further, the judgement result for whether needing lock operation to proactive and/or rear camera file in step S800 is
Be, then by proactive and/or rear camera file write-in it is proactive and/or after take the photograph locking video area；If it is determined that result be it is no, then write
Enter it is proactive and/or after take the photograph ordinary video region.
The invention has the benefit that the technical program effectively reduce video file content can with Coutinuous store hard
The fragmentation of disk is obviously improved the writing speed of file, in addition, also having scalability strong, superstructure is without making volume
Outer modification can compatible files configuration list file system advantage.
