Abstract
The invention provides a digital video data hard disk storage method. A hard disk does not need to be formatted, video data are directly stored in logic access modes of magnetic heads, cylindrical surfaces, magnetic tracks and sectors, and the monitoring data are stored in two parts which are a data index table and the video data respectively. The method specifically includes the following steps that the data index table is established, the 100 sectors starting from the first cylindrical surface, the first magnetic head and the first sector serve as indexes of the monitoring data, each sector is stipulated to be provided with 1024 bytes, an index data format is fixed, each index represents a video record starting from the position, where the video record at the moment is stored, in a magnetic disk and the total number of the bytes of the record starting from the position, the indexes are not file indexes, and the data format of the starting position where the data are stored is shown as a camera serial number + year + month + day + hour + minute + second + cylindrical surface number + magnetic head number + sector number + byte + total data length.
Description
Technical field
The present invention relates to technical field of video monitoring, specifically a kind of hard-disc storage method of digital of digital video data.
Background technology
In video monitoring system, the storage of data is very important technical problems.The storage of video monitoring data, generally adopts digital compression technology, and data are stored in hard disk with document form.As time goes on, disk needs ceaselessly to delete ancient deed, records new file.Disk fragments gets more and more, and causes the speed of accessing disk to slow down.This patent adopts a kind of method of science, improves the efficiency of video monitoring data disk storage, reduces the failure rate of disk.
Video data compression adopts certain algorithm, video image data compression become one group of group data, Coutinuous store.Monitor data generally needs to preserve the regular hour, when disk reach residual capacity less time, need to delete data the earliest, for new data vacates memory space.
Storage medium is generally hard disk.Hard disk needs to format according to certain rule.
Monitoring image playback needs to retrieve according to the time.The faster the better for retrieval rate.
Summary of the invention
The object of this invention is to provide a kind of hard-disc storage method of digital of digital video data.
The object of the invention is to realize in the following manner, do not need disk format, the storage of video data directly stores with magnetic head, cylinder, magnetic track, sector logical access mode, supervising data storage is divided into two parts, a part is data directory, another part is video data, and concrete steps are as follows:
1) data directory: 100 sectors that the first cylinder, the first magnetic head, the first sector start are as the index of monitor data, every sector is defined as 1024 bytes, index data form is fixed, represent that the videograph in this moment leaves that the position of disk starts in, and the total bytes of record from this position, this index is not file index, and the starting position data format of representation of knowledge deposit data is as follows:
Camera number+year+moon+day+time+point+second+cylinder number+head number+sector number+byte position+data total length;
2) video data recording:
Video monitoring data leaves the later sector of concordance list in order in;
Data format: packet numbers+data content;
Data number is started from scratch, and represents the storage order of packet, produces a data directory at interval of the time of one, and concurrent video data record Bale No. makes zero, and increases Bale No. successively and stores data;
3) data cover mode:
When disk size reaches capacity, data need to restart cover data;
Data cover needs to cover two parts, and first, the Article 1 index of data directory covers, and then record data also cover, without the need to deleting legacy data from starting position, video data recording district.
The invention has the beneficial effects as follows: do not need disk format, the storage of video data directly stores with magnetic head, cylinder, magnetic track, sector logical access mode, and supervising data storage is divided into two parts, and a part is data directory, another part is video data, and retrieval rate is fast.
Embodiment
Hard disk does not need format, and the storage of video data directly stores with magnetic head, cylinder, magnetic track, sector logical access mode.Supervising data storage is divided into two parts, and a part is data directory, and another part is video data.
1) data directory: 100 sectors that the first cylinder, the first magnetic head, the first sector start are as the index of monitor data, and every sector is defined as 1024 bytes, and index data form is fixed.Represent that the videograph in this moment leaves that the position of disk starts in, and the total bytes of record from this position.This index is not file index, and the starting position data format of representation of knowledge deposit data is as follows:
Camera number+year+moon+day+time+point+second+cylinder number+head number+sector number+byte position+data total length.
2) video data recording:
Video monitoring data leaves the later sector of concordance list in order in.
Data format: packet numbers+data content.
Data number is started from scratch, and represents the storage order of packet.Produce a data directory at interval of the regular hour (15 minutes or 30 minutes or 60 minutes), concurrent video data record Bale No. makes zero, and increases Bale No. successively and stores data.
3) data cover mode:
When disk size reaches capacity, data need to restart to cover number, according to.
Data cover needs to cover two parts, and first, the Article 1 index of data directory covers, and then record data also cover, without the need to deleting legacy data from starting position, video data recording district.
Except the technical characteristic described in specification, be the known technology of those skilled in the art.
