Abstract
The invention discloses the implementation method that a kind of video file suspension of monitoring device resumes, technical solution is achieved in that, NVR is restarted or network is when abnormality is restored, and checks the whether complete of video file；NVR calculates the initial time for losing video file, is accurate to the second；Whether the IPC equipment that NVR is inquired on corresponding recording channel, which has, is locally stored (SD card etc.)；If there is video file lost in NVR in the storage on IPC, downloading request is initiated, the corresponding data in corresponding video file is downloaded.In the case where IPC is stored without destroying, the video file of most of loss can be given for change and repair.
Description
Technical field
The invention belongs to security industry field of video monitoring, in particular to a kind of monitoring device is in web camera and network
There is abnormal video file under the video file deletion condition for causing video recorder hard disk to be deposited in the communication network between video recorder
Recovery method.
Background technique
In field of video monitoring, most commonly used equipment is IPC(web camera) and NVR (network hard disk video recorder).
For video data, IPC is the collection terminal of data, and the end NVR is the receiving end of data.Usual NVR can connect multichannel simultaneously
IPC generally has 4/8/16/32/64 even more number.NVR will record the video recording of corresponding number simultaneously, and according to certain
Time interval (usual 10 ~ 30 minutes) is packaged into video file, stores in a hard disk, in case examination.
Since the video data transmission between IPC and NVR is the transmission carried out by Ethernet or wide area network, following two
The HD recording file that situation will lead to NVR is lost: the power-off of 1.NVR unit exception.Network interruption between 2.IPC and NVR, IPC
Cause video data that can not transmit extremely with the connection status of NVR.
Although the video file lost on NVR can be obtained by extracting the SD card of IPC, but there is problems in that
1. being not easy to carry out multichannel playback on NVR, check that a situation arises for alarm from different directions, is not easy to the unified pipe of video file
Reason.2. need the client software in addition opening IPC to go to check, it is time-consuming and laborious, or even climbing is needed to go to remove SD storage to IPC
Card, poor user experience.
In order to optimize the above user experience, the invention proposes a kind of method that suspension resumes video file, in NVR and
After the network recovery of IPC, the video file of the automatic correspondence period for downloading the loss on IPC enhances user experience.
Summary of the invention
The present invention is in order to solve current NVR equipment when recording the video recording of IPC, Network status is bad or NVR equipment
When power supply instability, lead to the problem of video file is lost on NVR.Propose a kind of method for restoring the video file on NVR.
Application scenarios of the present invention are as shown in Figure 1.
A kind of implementation method that the video file suspension of monitoring device resumes, the technical solution of realization are as follows:
Firstly, NVR is restarted or network is when abnormality is restored, the whether complete of video file checked.
NVR calculates the initial time for losing video file, is accurate to the second.
Whether the IPC equipment that NVR is inquired on corresponding recording channel, which has, is locally stored (SD card etc.).
If there is video file lost in NVR in the storage on IPC, downloading request is initiated, corresponding video recording is downloaded
Corresponding data in file.
The correspondence I frame of the video file downloaded to, B frame, P frame etc. are corresponded to video recording packetization types, weight by NVR by NVR
The new video file that is packaged is stored back to hard disk.
A kind of implementation method that the video file suspension of monitoring device resumes, technical solution effect are as follows:
In the case where IPC is stored without destroying, the video file of most of loss can be given for change and repair.
Detailed description of the invention
Attached drawing 1 is application scenarios of the invention.
Attached drawing 2 is technical solution of the present invention detailed process.
Specific embodiment
In order to clarify the technical characteristics of the invention, with reference to the accompanying drawing, doing the specific embodiment of the invention into one
Walk explanation.
Application scenarios of the present invention are the video data transmission between IPC and NVR under being coupled by Ethernet or wide area network,
It is specific as shown in Figure 1.
Detailed process is as shown in Figure 2:
Firstly, NVR is restarted or network is when abnormality is restored, the whether complete of the channel video file for having turned on video recording checked
It is whole.
Such as find that video file is imperfect, NVR calculates the initial time for losing video file, and when with the school IPC, is accurate to
Second.
After the completion of when school, whether the IPC equipment that NVR is inquired on corresponding recording channel, which has, is locally stored (SD card etc.).
If there is video file lost in NVR in the storage on IPC, NVR initiates downloading request, downloads corresponding video recording
Corresponding data in file.
The correspondence I frame of the video file downloaded to, B frame, P frame etc. are corresponded to video recording packetization types, weight by NVR by NVR
The new video file that is packaged is stored back to hard disk.
Claims (2)
1. the implementation method that a kind of video file suspension of monitoring device resumes, which is characterized in that real by following technical solution
Existing: (1) NVR is restarted or network is when abnormality is restored, and checks the whether complete of video file；(2) NVR, which is calculated, loses record
As the initial time of file, it is accurate to the second；(3) whether the IPC equipment that NVR is inquired on corresponding recording channel, which has, is locally stored
(SD card etc.)；If there is video file lost in NVR in the storage on IPC, downloading request is initiated, corresponding video recording is downloaded
Corresponding data in file.
2. the implementation method that the video file suspension of monitoring device according to claim 1 resumes, it is characterised in that: NVR
By the correspondence I frame of the video file downloaded to, B frame, P frame etc. repacks video recording by the corresponding video recording packetization types on NVR
File is stored back to hard disk.
