Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
First, terms of art in the embodiments of the present application will be explained:
host computer that can be used for video monitoring: the High-Definition digital hard disk video recorder supports multichannel VGA (Video Graphics Array, video image array) and HDMI (High Definition Multimedia Interface, high-Definition multimedia interface) High-Definition video access, multichannel HD-SDI (High Definition-Serial Digital Interface, high-Definition digital component serial interface) camera access, multichannel High-Definition 1080P or 400W pixel network camera access, and realizes High-Definition video and audio real-time coding, video recording and recording with the highest resolution of 400W. The system can independently realize high-definition audio and video monitoring, and can also be networked to form a powerful security system so as to meet the requirements of video monitoring digitization, networking, high definition and intellectualization. The method can be widely applied to video monitoring in industries such as important meeting records and the like.
GUI (Graphical User Interface ): refers to a computer operated user interface that is displayed in a graphical manner.
In the related host computer for video monitoring, when the hard disk is formatted, a part of hard disk space is reserved as a recording partition for storing a recording buffer file, an I-frame index file, a TAG (TAG) file and a writing file, and specifically, the recording buffer file allocated for each optical drive is 17GB (Gigabyte). When no optical disc exists for a long time, if 1 recording buffer file is full, the 4GB (DVD) optical disc/17 GB (blue-ray optical disc) segment is marked as abnormal until a blank optical disc is detected, a backup recording mode is entered, and the abnormal segment is recorded in the optical disc in a backup way. At present, considering the subsequent expansion, several recording buffer files are allocated to each optical disc drive, for example, 4 optical disc drives are allocated to the number of the recording buffer files, so that each optical disc drive is required to be allocated to the maximum of 17 x 4 = 68GB space, two optical disc drives are 136GB, and the number of the hard disc spaces reserved for the I-frame index, the TAG and the recording file is required to be 136GB more, and considering the subsequent expansion, some optical disc drives can be reserved more, an integer is taken, and 150GB is reserved.
Since there may be multiple hard disks in the host available for video monitoring, and the user may pull out the hard disk that is already full of data during use for archiving, or evidence presentation, etc., and then replace it with a new unformatted hard disk. Because the recording function of the host computer used for video monitoring depends on the recording partition in the hard disk, the recording partition is allocated when the hard disk is formatted, so that any hard disk in the host computer used for video monitoring is taken away, and the normal operation of the recording function of the host computer used for video monitoring is not affected as long as at least one hard disk is reserved in the host computer used for video monitoring. However, this method has a disadvantage that the space of the data partition for storing data such as video is reduced, for example, four hard disks are available in the host for video monitoring, each hard disk has a capacity of 1TB, if the capacity of the recording partition is 150GB, the capacity of each hard disk for data partition is reduced by 150GB, and four hard disks are reduced by 600GB. .
In view of this, an embodiment of the present application provides a hard disk partitioning method, referring to fig. 1, the method includes:
s101, detecting whether each hard disk connected with the current equipment comprises a recording partition.
The hard disk partitioning method can be realized by an electronic device with an optical disk recording function, and specifically, the electronic device can be a host computer for video monitoring. In the following, a host computer usable for video monitoring is taken as an example to specifically describe the embodiment of the present application, it is to be understood that only the host computer usable for video monitoring is taken as an example to describe the embodiment of the present application, and any electronic device having an optical disc recording function may be used as a hardware main body for implementing the hard disc partitioning method of the embodiment of the present application.
When the preset detection conditions are met, a host machine capable of being used for video monitoring detects whether each hard disk connected with the host machine comprises a recording partition or not. The preset detection conditions can be set according to actual conditions, for example, the preset detection conditions are set to be that when a host machine which can be used for video monitoring is started each time, the host machine which can be used for video monitoring detects whether each hard disk connected with the host machine comprises a recording partition or not; or when each time the connected hard disk is detected to be pulled out, the host computer which can be used for video monitoring detects whether each hard disk connected with the host computer comprises a burning partition; or the host computer for video monitoring periodically triggers and detects whether each hard disk connected with the host computer comprises a recording partition or not according to a preset detection period.
S102, when the number of the hard disks comprising the recording partition is N, selecting N-1 hard disks from the hard disks comprising the recording partition to obtain each hard disk to be released, wherein N is an integer greater than 1;
for example, from the N hard disks including the recording partition, N-1 hard disks may be randomly selected as the hard disks to be released; or according to the interface number of the hard disk, selecting N-1 hard disks from N hard disks containing the recording partition according to the sequence of the interface number, and taking the N-1 hard disks as hard disks to be released and the like. Of course, other relevant selection methods may be adopted, and will not be described in detail herein.
S103, dividing the recording partitions in each hard disk to be released into data partitions.
In one possible implementation, the partition header information of the hard disk may be modified first, and the modification method of each item of content may be as shown in table 1.
TABLE 1
Then the index database is required to be rebuilt, and finally the recorded partition of the hard disk is deleted. In the whole process of dynamically recovering the recorded partition, the data such as the log, the video, the index, the event information and the like in the original data partition can not be destroyed, and the recorded partition can still be read and written normally after the dynamic recovery is finished. Specifically, a flow chart of dynamic recovery of the recording partition is shown in fig. 7.
In a possible implementation manner, the hard disk partitioning method of the embodiment of the present application further includes:
and A, when each hard disk does not contain a recording partition, selecting a hard disk with a residual space not smaller than a preset recording space from each hard disk to obtain a target hard disk, wherein the preset recording space is a space required by the recording partition.
The preset recording space is the space size required by the recording partition, and in one possible implementation, the preset recording space size is 150GB. When the host computer for video monitoring detects that the connected hard disks do not contain the recording partition, the residual storage space, namely the residual space, in the hard disks connected by the host computer for video monitoring is detected. And selecting a hard disk with the residual space not smaller than the preset recording space to obtain a target hard disk. For example, a hard disk with the largest remaining space can be selected as a target hard disk from the hard disks with the remaining space not smaller than the preset recording space; or randomly selecting one hard disk from the hard disks with the residual space not smaller than the preset recording space as a target hard disk; or sequentially detecting the size of the residual space of each hard disk according to the interface sequence, stopping continuous detection and taking the currently detected hard disk as a target hard disk when the currently detected residual space of the hard disk is not smaller than the preset recording space, and the like.
Typically, the hard disk connected to the host, which may be used for video monitoring, needs to be formatted for use, and in one possible embodiment, referring to fig. 2, the method further includes:
s201, when a formatting instruction for a specified hard disk is acquired, detecting whether the other hard disks connected with the current device except the specified hard disk contain a recording partition or not.
S202, dividing the appointed hard disk into a data partition and a recording partition when the other hard disks do not comprise the recording partition.
When the recording partition is not included in any other hard disk except the specified hard disk, which is connected to the host computer and can be used for video monitoring, the specified hard disk is divided into a data partition and a recording partition, for example, one possible hard disk partition may be as shown in fig. 3.
And S203, initializing the appointed hard disk as a hard disk of a data partition when the other hard disk comprises a recording partition.
When other hard disks include a recording partition, for example, as shown in fig. 4, the hard disk is designated to include a data partition after initialization, and not include a recording partition.
Specifically, the process of formatting the hard disk may include, as shown in fig. 5:
step one, a formatting instruction for a specified hard disk is acquired.
Step two, judging whether the current equipment is connected with only one hard disk, if the current equipment is connected with only one hard disk, executing step five, and if the current equipment is connected with at least two hard disks, executing step three.
And step three, judging whether other hard disks comprise the recording partition, if the other hard disks comprise the recording partition, executing the step four, and if the other hard disks do not comprise the recording partition, executing the step five.
Initializing the appointed hard disk as the hard disk of the data partition.
And fifthly, dividing the appointed hard disk into a data partition and a recording partition.
After the current device is started, when a certain hard disk is formatted, the hard disk may be a hard disk newly installed in the device, may be a hard disk used for a period of time, may be only the hard disk in the device, and may also be a plurality of hard disks. Firstly, judging whether the current equipment has only one hard disk, if so, directly formatting the hard disk into the hard disk with the recorded partition. If there are other hard disks in the current device, it is necessary to further determine whether at least one of the other hard disks already has a recording partition, if so, the hard disk to be formatted is formatted into a hard disk with only a data partition, and if not, the hard disk to be formatted into a hard disk with a recording partition.
For example, a user connects an unformatted hard disk 1 to a host that can be used for video monitoring, detects the hard disk 1 after the host that can be used for video monitoring is started, formats the hard disk 1, and when detecting that the hard disk 1 is the only hard disk in the device, generates a data partition and a recording partition when formatting the hard disk 1. The user connects an unformatted hard disk 2 to a host computer which can be used for video monitoring, detects the hard disk 2 after the host computer which can be used for video monitoring is started, formats the hard disk 2, and only generates a data partition and does not generate a recording partition when detecting that the host computer which can be used for video monitoring already has the hard disk 1 with the recording partition.
In view of the foregoing formatting manner, in one possible implementation manner, when the foregoing hard disks do not include a recording partition, selecting a hard disk with a remaining space not smaller than a preset recording space from the respective hard disks to obtain a target hard disk, where the method includes:
when the hard disks do not contain the recording partition, selecting a hard disk with the residual space not smaller than the preset recording space from the hard disks which are obtained by formatting and comprise the data partition but not the recording partition, and obtaining the target hard disk.
For example, the hard disk including the data partition but not including the recording partition obtained by formatting is called a pure data hard disk, and the pure data hard disk with the largest remaining space can be selected from the pure data hard disks with the remaining space not smaller than the preset recording space as the target hard disk; or randomly selecting a pure data hard disk from the pure data hard disks with the spare space not smaller than the preset recording space as a target hard disk; or sequentially detecting the residual space of each pure data hard disk according to the interface sequence, stopping continuous detection and taking the currently detected pure data hard disk as a target hard disk when the residual space of the currently detected pure data hard disk is not smaller than the preset recording space, and the like.
Specifically, the process of obtaining the target hard disk may be as shown in fig. 6, and includes:
step one, detecting that the current equipment is not connected with a hard disk containing a recording partition.
And step two, judging whether the current equipment is connected with a pure data hard disk which is obtained by formatting and comprises a data partition but does not comprise a recording partition, executing the step four if the current equipment is connected with the pure data hard disk, and executing the step three if the current equipment is not connected with the pure data hard disk.
And thirdly, prompting that the current equipment does not have a hard disk suitable for distributing the recording partition.
And step four, judging whether the pure data hard disk has a hard disk with the residual space not smaller than the preset recording space, if the pure data hard disk comprises the hard disk with the residual space not smaller than the preset recording space, executing step six, and if the pure data hard disk does not comprise the hard disk with the residual space not smaller than the preset recording space, executing step five.
And fifthly, prompting that the capacity of the hard disk in the current equipment is insufficient to allocate the recording partition, and requesting to replace or format the hard disk.
And step six, selecting a pure data hard disk with the residual space not smaller than the preset recording space to obtain a target hard disk.
If there are two or more hard disks in the present apparatus, according to the method for formatting hard disks, only one hard disk of these hard disks is a hard disk with a recording partition, and the other hard disks are hard disks without formatting or after formatting, do not include a recording partition. At this time, if the hard disk with the recording partition in the current device is pulled out, the hard disk with the recording partition does not exist, and the recording function cannot operate normally. The state of each hard disk needs to be monitored in the background, and when the hard disk with the recording partition is not available in the current equipment, a proper hard disk is selected from the rest hard disks to dynamically allocate the recording partition.
When the fact that the current device is not connected with the hard disk containing the recording partition is detected, whether the current device is connected with the hard disk which is obtained through formatting and comprises the data partition but does not comprise the recording partition (hereinafter referred to as a pure data hard disk) is detected, when the current device does not have the pure data hard disk, interface interaction service or network service is notified, and a client or a GUI is prompted that the hard disk which is suitable for distributing the recording partition is not available at present; if one or more pure data hard disks are detected in the current equipment, checking whether the residual space of the pure data hard disks is not smaller than the preset recording space (the space required by the recording partition) one by one according to the sequence of the hard disk numbers, and taking the first pure data hard disk meeting the condition as a target hard disk; if none of the pure data hard disks satisfies the condition, the interface interaction service or the network service is notified, and the client or the GUI is prompted to indicate that the capacity of the hard disk in the device is insufficient to allocate the recording partition, please format a hard disk, or replace a proper hard disk.
And B, dividing the recording partition in the target hard disk.
Selecting a region with a preset recording space size from the residual space of the target hard disk, dividing the region into recording partitions, and correspondingly modifying the header information of the target hard disk.
In one possible implementation manner, the dividing the recording partition in the target hard disk includes:
step one, according to the size of the recorded partition, updating the size of the data partition in the head information of the target hard disk partition, updating the size of an index database in the head information of the target hard disk partition, updating the initial offset and the length of the related index, and updating the size of the data partition.
The hard disk partition header information may further include a maximum number of video files, and in a possible implementation manner, the method further includes:
and updating the maximum video file number in the target hard disk partition head information according to the size of the recording partition.
First, the partition header information of the target hard disk is modified, and the updating method of each content can be shown in table 2.
TABLE 2
And step two, dividing the recording partition in the target hard disk.
Reconstructing the index database, and formatting the last part of storage space of the target hard disk into a recording partition. In the process of dynamically distributing the recording partition, the data such as the log, the video, the index, the event information and the like in the original data partition can not be destroyed, and the normal reading and writing can still be carried out after the dynamic distribution of the recording partition is finished.
If one hard disk with the recording partition exists in the current equipment, one or more hard disks with the recording partition are inserted at the moment, and a plurality of hard disks with the recording partition exist in the equipment. In order to reduce the waste of storage space, only one hard disk with a recording partition is reserved, and the recording partitions in the other hard disks with the recording partitions are recovered and distributed into the data partitions for recording.
The following illustrates a hard disk partitioning method according to an embodiment of the present application, and the hard disk partitioning process may be as shown in fig. 8.

The user connects an unformatted hard disk to a host interface 2 which can be used for video monitoring, the host which can be used for video monitoring detects the hard disk 2, formats the hard disk 2, and only generates a data partition and does not generate a recording partition when detecting that the host which can be used for video monitoring already has the hard disk 1 with the recording partition.
After a period of use, due to the needs of archiving or evidence displaying, etc., the user pulls out the hard disk 1, detects that the hard disk 2 is the only hard disk in the device, but does not have a recording partition, the recording function cannot be normally operated, at this time, dynamic allocation operation can be started, the space of the last unwritten data in the hard disk 2 is formatted, the recording partition is generated, and the operation cannot influence the recorded data such as video, log, event information, etc. in the data partition in the hard disk 2.
If a hard disk including the recording partition is inserted into the host interface 1 for video monitoring, when the number of the hard disks including the recording partition in the host for video monitoring is detected to be 2, the recording partition in the hard disk 2 is dynamically recovered.
