[0016] Further, when the status monitoring unit detects that the main server resumes operation, it sends a normal operation signal to the control unit;

[0017] After receiving the normal operation signal, the control unit controls the main server to resume video storage and suspends the operation of the corresponding standby server.

[0038] An embodiment of the present invention provides a method for storing video recordings with high availability. Figure 1 , Figure 1 The flowchart of the method for storing video recordings in a primary-backup manner with high availability in one embodiment of the present invention includes steps S11 to S14:

[0039] Step S11, in response to the recording signal sent by the control unit, the recording unit obtains real-time image data and sends the real-time image data to the main server; the main server processes the received real-time image data and stores the real-time image data in the image database.

[0040] With the increasing demand for monitoring storage functions, the traditional single-server video storage system has gradually been unable to meet the video storage needs due to the limitations of single point failure risk, data security risk, maintenance cost, etc. Therefore, the embodiment of the present invention adopts an M+N master-slave server mode to perform video recording and storage operations of monitoring data. Specifically, the solution of this embodiment adopts a combination of multiple master servers and multiple backup servers to realize the video recording and storage functions.

[0041] The system of this embodiment is controlled by a control unit, and the video recording unit is composed of multiple video cameras for obtaining monitoring screen data in real time.

[0042] During the specific recording process, the control unit is responsible for the overall control and scheduling of the monitoring system. When recording is required, it will send a recording signal as the starting point of the entire recording process.

[0043] After receiving the recording signal, the recording unit captures real-time image data and needs to send this data to the main server for processing and storage. This step is the key to data transmission, which ensures that the real-time image data can be transmitted to the main server in a timely and accurate manner.

[0044] As the core part of the monitoring system, the main server is responsible for processing the received real-time image data, including data decoding, compression, format conversion and other operations to ensure that the data can be stored in the image database in an efficient and accessible manner. After completing the data processing steps, the processed real-time image data and timestamp are stored in the image database together.

[0045] Step S12, in response to the video recording signal sent by the control unit, the operation status monitoring unit monitors the operation status of the main server in real time, and sends an abnormal signal to the control unit after detecting abnormal data of the main server.

[0046] During the operation of the monitoring system, the status monitoring unit continuously monitors the operating status of each main server and backup server in real time, including key indicators such as CPU utilization, memory utilization, network bandwidth, etc., to ensure that the main server can process real-time image data normally.

[0047] When abnormal data is detected on the main server, such as performance degradation, insufficient resources, etc., the operation status monitoring unit will immediately send an abnormal signal to the control unit so that the system can take timely measures.

[0048] Step S13: After receiving the abnormal signal, the control unit starts the alternative server and controls the video recording unit to send the real-time image data to the alternative server.

[0049] The control unit is the command center of the system and is responsible for receiving signals from various monitoring units. When receiving an abnormal signal from the operation status monitoring unit, the control unit will immediately identify possible problems with the main server.

[0050] After confirming that the main server is abnormal, the control unit will start the backup server. Preferably, the backup server is pre-configured and can take over the tasks of the main server when it cannot work normally. Specifically, the method of pre-configuring the backup server in this embodiment is: the available backup servers are selected through a campaign to replace the failed server with the highest priority as the backup server to replace the main server during the failure.

[0051] Since there are multiple main servers in the monitoring system, in order to improve resource utilization efficiency and achieve high availability of the system, multiple available backup servers can serve as backup options for multiple main servers at the same time. When a main server fails, the optimal backup server replaces the main server to perform the video storage function, and the backup server is temporarily deleted from the backup queue of other main servers.

[0052] When a main server fails, the best one can be quickly selected from the backup servers to take over the work, without having to configure a backup server for each main server, thus saving a lot of hardware resources. When a backup server is selected to take over the work of a main server, it will be temporarily deleted from the backup queue of other main servers. This method of dynamically adjusting the backup queue ensures that each backup server can take over the work in the best state when needed, avoiding waste of resources and conflicts.

[0053] Step S14: the candidate server receives and processes the real-time image data, and stores the real-time image data in the image database.

[0054] After taking over the work of the main server, the backup server seamlessly receives real-time image data from the surveillance camera and performs necessary processing, such as decoding and compression, to ensure data readability and storage efficiency.

[0055] In order to effectively splice the video data stored in the main server and the standby server later, the standby server also needs to record and store the timestamp information when storing the real-time image data.

[0056] When the standby server takes over the main service, the standby server acts as a temporary main server, and the status monitoring unit also monitors the working status of the temporary main server. The specific monitoring process is the same as the process of detecting the main server.

[0057] When the status monitoring unit detects that the operation status of the temporary main server fails, a new optimal standby server selected in advance is selected from the remaining standby servers to take over the work.

[0058] At the same time, the status monitoring unit also keeps monitoring the main server at all times. Once it detects that the main server has resumed normal operation, it sends a normal operation signal to the control unit. After receiving the normal operation signal, the control unit controls the main server to resume video storage and suspends the operation of the corresponding standby server.

[0059] By continuously monitoring the status of the primary server and switching back to the primary server in time when it returns to normal, the system can maintain higher stability and reduce the potential risk of failure caused by the long-term operation of the backup server. In addition, the backup server can be released and re-enter the election queue of each primary server, thus avoiding the waste of resources. This dynamic resource allocation method enables the system to use hardware resources more efficiently.

[0060] After the switch between the primary and backup servers occurs, the monitoring video is temporarily interrupted. Therefore, it is necessary to synthesize the real-time image data of each continuous time. Specifically, the method adopted in this embodiment is: select the real-time image data with corresponding timestamps in the image database, and splice and synthesize them by video frame splicing to form a complete video.

[0061] During the video stitching process, you need to pay attention to the transition effect between the previous and next videos to avoid obvious jumps or flickers. In addition, if there is jitter between the two videos, you need to perform de-jitter processing after stitching to improve the stability of the video.

[0062] After stitching is completed, the quality of the stitched video is evaluated. The specific evaluation content includes visual quality, stitching traces, peak signal-to-noise ratio, structural similarity and other aspects.

[0063] Preferably, during the operation of the monitoring system, all fault operation data and server switching data are saved and recorded, and a video storage fault log file is generated based on the recorded historical data. By recording and analyzing fault data, the system design and configuration can be continuously improved, the system's fault tolerance and self-healing capabilities can be improved, which helps to enhance the system's reliability and ensure the smooth progress of monitoring tasks.

[0064] When the main server fails, the backup server can immediately take over the storage task to ensure the continuity and integrity of the surveillance video; the backup server can copy data from the main server in real time or periodically to achieve real-time backup and disaster recovery backup of data. Even if the main server fails, the backup data can still be restored and used.

[0065] The embodiment of the present invention further provides a primary and secondary high-availability video storage device, which is used to execute the primary and secondary high-availability video storage method as described above.
