Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
According to the method, the redundant disk space in the disk is determined through detecting the storage time of the video files, and the target video files corresponding to the target video channels which do not meet the storage requirement are stored into the corresponding target redundant disk space according to the planned video storage chain, so that the storage time of the video files is prolonged.
In order that the above-described aspects may be better understood, exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
Example 1
During video recording, a situation may be encountered in which the disk is damaged, or disconnected. In this case, it is difficult to satisfy the storage requirement of the video file for the storage time of the video file. In order to prolong the storage time of a video file and meet the storage requirement of the video file, an embodiment of the present application provides a method for prolonging the storage time of the video file, and referring to fig. 1, fig. 1 is a schematic flow chart of a first embodiment of the method for prolonging the storage time of the video file.
In this embodiment, the method for prolonging the storage time of the video file includes:
Step S10: acquiring video file time marks corresponding to all video channels in a storage space, and determining a redundant disk space according to the video file time marks and storage requirements corresponding to all the video channels;
In this embodiment, the video detection system may determine, by traversing each video channel, a video file corresponding to each video channel in the storage space. Meanwhile, according to the time mark of the video file, the recording time of the video file can be determined. According to the video file with the earliest recording time in the video files corresponding to the video channels, the storage time of the video files which can be stored in the storage space corresponding to the video channels can be determined.
Under the actual application scene, each video channel may have different storage requirements according to the video schedule. For example, in a financial scenario, it is common for a video file to require a video file retention time of ninety days or more to ensure that the video file can provide effective support. The video detection system judges whether the storage space meets the storage requirement according to the storage time of the video file in the storage space and according to the storage time threshold value in the storage requirement. Meanwhile, when the storage space meets the storage requirement, the video recording detection system can determine the redundant disk space of the storage space according to the storage time threshold.
It should be noted that, the video recording device performs video recording according to a preset video recording plan, and after each video recording file is generated, the generated video recording file is stored in a corresponding storage space in the magnetic disk through the video recording channel. When the residual space of the storage space is insufficient to store the received video files, the received video files are covered with the video files with the earliest storage time, so that the video files can be ensured to be stored normally, and the normal operation of video is maintained.
As an alternative implementation of determining the redundant disk space, the video detection system may traverse each video channel and determine a video file corresponding to the video channel in the storage space, and a video file time stamp of the video file. According to the video file time mark, the video detection system can determine the video file preservation time of the video channel. Meanwhile, according to the storage requirement corresponding to the video channel, the storage time threshold of the video file can be determined. The video detection system calculates the difference between the storage time of the video file and the threshold value of the storage time, and sums the calculation result with the remaining storage space of the storage space to determine the redundant disk space of the storage space.
As another alternative implementation mode for determining redundant disk space, the video detection system can determine the generation time of the video file through the time watermark of the video file when traversing the video channels, and determine the storage time of the video file of each video channel according to the generation time. Meanwhile, according to the storage time threshold corresponding to the storage requirement of the video channel, the video detection system can calculate redundant disk spaces of all storage spaces.
In an exemplary embodiment, after determining the video file in the storage space of the video channel, the video detection system may extract a target frame picture of the video file, and determine a corresponding time string according to a time watermark on the target frame picture. By identifying the time string, the video detection system may determine the recording time of the video file and determine the save time of the video file. The target frame picture may be a first frame picture in the video file, or may be a last frame picture in the video file.
Step S20: when the video file storage time corresponding to the target video channel is detected not to meet the storage requirement, sequencing the redundant disk space according to the redundant storage capacity of the redundant disk space;
Step S30: and determining a video storage chain according to the sorting result, and storing the target video file into a target redundant disk space based on the video storage chain.
In this embodiment, when it is detected that the storage time of the video file corresponding to the target video channel does not meet the storage requirement, that is, when the storage time of the video file of the target video channel is smaller than the storage time threshold in the storage requirement, the video detection system ranks the redundant disk spaces according to the redundant storage amounts of the redundant disk spaces. According to the sorting result and a preset algorithm, the video detection system can generate a video storage chain. The storage sequence of the target video file in the redundant disk space is recorded in the video storage chain. After the video storage chain is generated, the video detection system can disable the target video channel, and store the target video file into the target redundant disk space according to the video storage chain. The preset algorithm may determine the target video file according to the video file of the target video channel and determine the video storage chain, or may determine the target video file according to a time interval between a storage time and a storage time threshold of the video file of the target video channel and determine the video storage chain.
As an alternative implementation manner for determining the video storage chain, the video detection system may plan the video storage chain according to all video files of the target video channel, and store all video files as target video files according to the video storage chain to the target redundant disk space. The video recording detection system can add the redundant disk space with the largest redundant memory space into the redundant space queue according to the sequencing result of the redundant disk space. Meanwhile, according to the sum of the redundant memory amounts of the redundant disk spaces in the redundant space queue and the memory amount threshold corresponding to the memory requirement, whether the redundant disk spaces in the redundant space queue can meet the memory requirement can be judged.
Further, when the sum of the redundant storage amounts is smaller than the storage amount threshold, the video recording detection system can continuously add the redundant disk space into the redundant space queue in sequence according to the sequencing result. When the sum of the redundant memory amounts is larger than the memory threshold value, the video detection system judges that the redundant disk space in the redundant space queue meets the memory requirement, outputs a video memory chain according to the redundant space queue, and empties the redundant space queue. According to the video storage chain, the target redundant disk space can store target video files according to the storage requirement.
In specific implementation, the video detection system also updates the target redundant disk space according to the storage action of the target video file. The video detection system can determine the storage capacity of the target video files stored in each target redundant disk space according to the video storage chain, and update the redundant storage capacity of the target redundant disk space according to the storage capacity. By updating the redundant memory capacity of the target redundant disk space, the video detection system can update the sequencing result of the redundant disk space according to the redundant memory capacity and more reasonably plan the video memory chain.
For example, when there is a redundant disk space whose redundant storage meets the storage requirement, the video recording detection system may also add the redundant disk space with the largest redundant storage to the redundant space queue according to the sorting result of the redundant disk space. And meanwhile, independently generating a video storage chain according to the redundant disk space meeting the storage requirement, and storing the target video file.
As another alternative implementation manner of determining the video storage chain, the video detection system may determine the time difference of the corresponding missing video file only according to the video time of the target video channel missing based on the storage requirement, and plan the video storage chain. The video detection system can determine the target video file and the target storage amount of the target video file according to the time difference between the video file storage time of the target video channel and the storage time threshold of the storage requirement. The video detection system may generate a video storage chain based on the target storage amount.
Further, the video detection system determines a corresponding target redundant disk space and a target storage amount of a target video file of the target redundant disk space according to a video storage chain. According to the target storage amount, the video detection system can allocate a corresponding channel access parameter for the target redundant disk space, and set a target video channel corresponding to the target redundant disk space to be enabled. The channel access parameters include, but are not limited to, the ip of the camera, the user name, the password, and the number of days required for video recording.
For example, the video recording detection system adds the redundant disk space with the largest redundant memory space to the redundant space queue according to the sequencing result, and determines the sum of the redundant memory spaces of the redundant space queue. When the sum of the redundant storage amounts is smaller than the target storage amount, video detection can continue to sequentially add the redundant disk space into the redundant space queue according to the sequencing result, and when the sum of the redundant storage amounts is larger than the target storage amount, a video storage chain is output according to the redundant space queue, and the redundant space queue is emptied. According to the video storage chain, the video detection system can store the target video file into the target redundant disk space, and update the target redundant disk space according to the storage action of the target video file.
According to the embodiment of the application, by traversing each video channel, determining the redundant disk space in the storage space according to the storage time of the video files in the storage space of each video channel, planning the video storage chain according to the redundant disk space, and storing the target video files corresponding to the target video channels which do not meet the storage requirement into the target redundant disk space, the storage time of the video files is prolonged, so that the video files can provide more effective support for the examination and analysis process.
Example two
Based on the same inventive concept, the present application also provides a second embodiment, and referring to fig. 2, fig. 2 is a schematic flow chart of a second embodiment of the method for prolonging the storage time of video files according to the present application.
In this embodiment, after determining a video storage chain according to the sorting result as described in step S30 and storing the target video file into the target redundant disk space based on the video storage chain, the method further includes:
Step S31: after receiving the target video file sent by video equipment, acquiring a corresponding video storage chain according to the video equipment;
Step S32: according to the storage space corresponding to the video storage chain, determining a corresponding target time mark in the storage space;
step S33: and calculating the preservation time corresponding to the target time mark, selecting a target storage space with the longest preservation time, and sending the target video file to the target storage space.
In this embodiment, after determining that the target video channel does not meet the corresponding storage requirement, the video detection system disables the target video channel and associates the generated video storage chain with the video device corresponding to the target video channel. After the video recording device generates the target video recording file, the video recording device determines a target storage space in the redundant disk space according to the associated video recording storage chain, and sends the target video recording file to the target storage space.
As an alternative implementation of determining the target storage space, the video recording device may determine the storage space corresponding to the video storage chain, and determine the target video file stored in the storage space. According to the target time mark of the target video file, the storage time of the target video file can be determined. The video recording device may select a storage space corresponding to the target recording file with the longest storage time as a target storage space, and send the generated target recording file to the target storage space.
As another alternative implementation way for determining the target storage space, the video recording device may also determine a history storage node of the target video file according to the history storage record. According to the history storage node, the video recording device can determine the next storage node in the video recording storage chain, determine a corresponding target storage space according to the storage node, and send the generated target video file to the target storage space.
In the embodiment of the application, after finishing recording the video file, the video recording device can determine the target storage space according to the video recording storage chain so as to finish storing the target video file. The storage requirement of video can be met by storing the target video file and covering the target video file with the longest storage time corresponding to the video storage chain.
Since the system described in the second embodiment of the present application is a system for implementing the method in the first embodiment of the present application, based on the method described in the first embodiment of the present application, a person skilled in the art can understand the specific structure and the modification of the system, and therefore, the description thereof is omitted herein. All systems used in the method according to the first embodiment of the present application are within the scope of the present application.
Example III
Based on the same inventive concept, the present application further provides a third embodiment, and referring to fig. 3, fig. 3 is a schematic flow chart of a third embodiment of the method for prolonging the storage time of video files according to the present application.
In this embodiment, as described in step S10, before obtaining the video file time stamp corresponding to each video channel in the storage space and determining the redundant disk space according to the video file time stamp and the storage requirement corresponding to each video channel, the method further includes:
step S11: acquiring a video detection plan and determining a detection time period;
Step S12: determining video detection time according to the historical video detection time and the detection time period;
Step S13: and when the current system time is the video detection time, executing the step of acquiring video file time marks corresponding to each video channel in the storage space, and determining redundant disk space according to the video file time marks and the storage requirements corresponding to each video channel.
In this embodiment, the video recording detection system may perform periodic video recording detection according to a preset video recording detection plan. The video recording detection plan includes, but is not limited to, a detection time period and a detected video recording channel range. The video recording detection system can determine the next video recording detection time according to the detection time period and the historical video recording detection time. The video detection plan can determine whether to execute video detection action according to the current system time, and execute video detection action to detect all video channels within the video channel range when the current system time is the video detection time.
For example, when the video recording detection is scheduled to be performed in a period of eight hours, the video recording detection system calculates the next video recording detection time according to the historical video recording detection time. For example, in the historical video detection time, the last video detection time is zero, and the video detection system can calculate that the next video detection time is eight points, and execute the video detection action when the current system time is eight points. Or when the historical video detection time is empty, the video detection system immediately executes a video detection action and records the historical video detection time.
According to the embodiment of the application, through the establishment of the video detection plan, the video detection system carries out video detection according to the preset video detection period, the storage time of the video file is judged at regular time, and whether all video channels can meet the storage requirement is judged in time, so that the video file is prevented from being lost.
