[0072] To further illustrate the technical solutions provided by the embodiments of the present application, the following will be described in detail with reference to the accompanying drawings and specific implementation manners. Although the embodiments of the present application provide method operation steps as shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or non-creative labor. In steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided by the embodiments of the present application. When the method is actually processed or executed by a control device, it may be executed in the order shown in the embodiments or drawings or executed in parallel.

[0073] Such as Figure 1As shown in the figure, it is a schematic diagram of a recording video recording and playing system in the related art, mainly including a video playing server 100, an NVR device 101, and a large storage device 102. Both the NVR device 101 and the large storage device 102 are connected to the video playing server 100. The large storage device 102 can be a central-level video network storage device (Central VideoRecorder, CVR) device; the NVR device 101 is together with an Internet Protocol Camera (IP Camera, IPC). After the camera records the video, it is stored in the NVR device 101. The large storage device 102 is deployed in the center, connecting cameras in various regions and storing the video files recorded by the cameras. The above NVR device and large storage device, as storage devices, are connected to the video playing server 100, and the video playing server 100 provides video playing services.

[0074] For the NVR device placed near the camera, there are difficulties in management. There are even situations where someone on-site deliberately shuts down, damages, or tampers with it, resulting in serious problems with the integrity and reliability of historical videos; it is impossible to provide centralized viewing, and one needs to go to the NVR device to view.

[0075] For the solution of placing the large storage device in the center, there is theoretically a problem of bandwidth bottleneck, and the camera needs to be exposed to the central network environment, resulting in camera network security problems.

[0076] In view of the data security problems of the NVR device and the bandwidth bottleneck of the central storage in the related art, this application proposes a recording video recording and playing system for providing recording video services for clients, such as Figure 2 As shown in the figure, the system includes:

[0077] At least one edge gateway node 201, which is used to receive the recording request sent by the server. The server is a central cloud storage server or a video playing server; generate a recording task according to the recording request, and determine the recording service for executing the recording task; start a corresponding number of cameras to execute the recording task through the recording service, and upload the obtained recording video file to the central cloud storage server;

[0078] The central cloud storage server 202 is used to receive the video playing request sent by the video playing server; the video playing request is used to request to play the target recording video file; the target recording video file is uploaded after the central cloud storage server requests the edge gateway node to start the recording service to complete the recording task; send the link of the target recording video file to the video playing server, so that the video playing server sends the link to the client, and the client plays the target recording video file according to the link;

[0079] The video playback server 203 receives a video playback request sent by the client based on edge node information and / or recording service information. The edge node information and / or recording service information are obtained by the video playback server from the central cloud storage server and synchronized to the client. The video playback server sends the video playback request to the central cloud storage server, receives the link of the recorded video file sent by the central cloud storage server, and obtains the recorded video file through the link.

[0080] The camera 204 is connected to the edge node 201 and is used for video recording under the control of the recording service started by the edge node 201.

[0081] The recording video recording and playback system provided by the embodiments of the present application proposes a unified and centralized central storage solution that supports cross-regions, stores the recorded video files in the central cloud environment, eliminates the problems of manual deletion, damage, and shutdown of the recorded videos, and at the same time supports the non-peer network structure between the camera and the storage environment, ensuring that the camera is not exposed to the upper-layer network, and provides a delay feedback mechanism to reduce network congestion problems.

[0082] The edge node of the embodiments of the present application is simultaneously connected to the central cloud storage server and the video playback server. The central cloud storage server is used to provide cloud storage services, and the recorded video files are stored in the central cloud environment composed of multiple devices, which can avoid the bandwidth bottleneck problem existing in the centralized storage of data. The video playback server provides a recorded video playback platform. The client can log in to the recorded video playback platform, establish a connection with the video playback server, and when it is necessary to play the recorded video file, send a video playback request to the video playback server. The video playback server obtains the link of the recorded video file from the central cloud storage server and sends it to the client, and the client obtains the recorded video file through the link.

[0083] The central cloud storage server of the embodiments of the present application may include a primary central cloud storage server and a standby central cloud storage server, so that when the primary central cloud storage server fails, the standby central cloud storage server can be started. For example, the IP addresses of the two central cloud storage servers are 10.169.42.113 and 10.169.42.114 respectively. One of them is used as the IP address of the primary central cloud storage server, and the other is used as the IP address of the standby central cloud storage server.

[0084] The above-mentioned edge network node can be flexibly deployed according to requirements. For example, according to the recording requirements, the local area network where the cameras meeting the recording requirements are located can be determined. After connecting the cameras in the same local area network to the edge network node, the edge network node registers with the central cloud storage server, so that communication with the central cloud storage server and the video playback server can be realized. During implementation, the edge network node can be flexibly deployed according to requirements. For example, different edge network nodes can be deployed in different local area networks. In a local area network, if the number of cameras is very large, multiple edge network nodes can be deployed according to requirements. Exemplarily, if the number of cameras that the started edge network node A in the local area network can connect to is less than 600, and the number of cameras in the local area network is greater than 600, another edge network node B can be deployed.

[0085] For each deployed edge network node, it is necessary to pre-create the information of the newly deployed edge network node in the central cloud storage server. In this way, after the subsequent edge network node sends a registration application to the central cloud storage server, it can be verified based on the pre-created information. If the information is consistent, the verification passes; otherwise, the verification fails. After the verification passes, the registration of the edge network node is completed, and the IP address assignment for the edge network node is realized. The same edge network node cannot initiate registration multiple times. If it initiates registration multiple times and fails, a verification failure will be prompted. Different edge network nodes are assigned different IP addresses. For example, the IP addresses assigned to two different edge network nodes are 192.168.1.12 and 192.168.1.19 respectively.

[0086] In the embodiment of the present application, the edge network node is further used to send a registration request to the central cloud storage server, so that after the central cloud storage server authenticates the registration request and passes, it synchronizes the edge network node information to the video playback server; the central cloud storage server is further used to receive the registration request sent by the edge network node and authenticate the identity of the edge network node; after the authentication passes, it synchronizes the edge network node information to the video playback server, so that the video playback server can send the edge network node information to the client in response to the request of the client. The video playback server receives the edge network node information synchronized by the central cloud storage server and establishes a link with the edge network node. In this way, in response to the request of the client, the edge network node information can be sent to the client and the edge network node information can be displayed on the client. In this way, after the client logs in to the recording video playback platform, the edge network node identifier can be viewed on the recording video playback platform. If it is necessary to send a recording request to a certain edge network node or a video playback request to play the recorded video file of a certain edge network node, the recording request or video playback request can be sent to the edge network node through the video playback server by clicking on the edge network node identifier.

[0087] In the embodiments of the present application, the number of recording services that the edge gateway node can start can be pre-configured. The number of cameras connected to one recording service is fixed, and the maximum number of recording services can be configured according to the load condition. For example, if one recording service can be connected to 32 cameras and the configured number of recording services is 10, then the maximum number of cameras that can be connected is 320.

[0088] In the embodiments of the present application, the edge gateway node is further configured to send the configured recording service information to the video playback server, so that the video playback server sends the recording service information to the client in response to a request from the client. The central cloud storage server is further configured to receive the recording service information sent by the edge gateway node and synchronize it to the video playback server, so that the video playback server sends the recording service information to the client in response to a request from the client. The video playback server receives the recording service information of the edge gateway node sent by the central cloud storage server and, in response to a request from the client, sends the recording service information to the client to display the recording service information on the client side. In this way, the video playback server can display the recording service information on the recording video playback platform, and the client can view the recording service information configured under a certain edge gateway node and can select to start a certain recording service for video recording or request to play the recorded video file of a certain recording service according to the requirements.

[0089] In the embodiments of the present application, the recording task includes a first recording task and / or a second recording task. The recording task can be generated according to a recording request in any of the following ways:

[0090] 1) When the recording request is a non-real-time recording request carrying a recording plan, generate the first recording task according to the recording plan; the first recording task is used to complete the required recording data at the required recording time;

[0091] The central cloud storage server can send a non-real-time recording request carrying a recording plan to the edge gateway node. The recording plan can be a recording plan for video recording in the future, including the start time of recording, the end time of recording, and recording data requirement information, such as recording data for a certain area. When the edge gateway node receives the non-real-time recording request, it generates the first recording task according to the recording plan, specifically determining the recording task of which cameras to start for recording during what time period.

[0092] 2) When the recording request is a real-time recording request, generate the second recording task; the second recording task includes the identifier of the target camera; the second recording task is used to start the target camera to record data and end the second recording task when a recording end request is received.

[0093] The client can view the edge gateway node information and recording service information based on the video playback platform, select to start a certain recording service for video recording, send a real-time recording request to the edge gateway node through the video playback server. After receiving the real-time recording request, the edge gateway node determines the started recording service according to the real-time recording request, and determines the target camera to be started according to the demand data, so as to generate a second recording task, start recording by executing the second recording task, and end the second recording task when the recording end time is reached. Specifically, the client can carry the recording duration or recording stop time in the recording request, end the recording when the recording duration or recording stop time is reached, or end the second recording task when receiving an end request.

[0094] In the embodiment of the present application, the edge gateway node determines the recording service for executing the recording task, including:

[0095] Obtain the resource occupancy information of the running recording services, where the resource occupancy information may include, but is not limited to, at least one of CPU usage rate, memory usage rate, or the number of cameras currently starting video recording;

[0096] Determine the remaining resources of the running recording services according to the resource occupancy information;

[0097] Determine the priority of the running recording services according to the remaining resources, and allocate the recording task to at least one recording service according to the priority.

[0098] For different resources, the more resources are occupied, the less remaining resources there are. Specifically, the following method can be used to determine the priority of the running recording services:

[0099] Determine the priority order of the corresponding running recording services from high to low in the order of increasing CPU usage rate;

[0100] If it is determined that there are multiple running recording services at the same priority, determine the priority order of the corresponding running recording services from high to low in the order of increasing memory usage rate;

[0101] If it is determined that there are multiple running recording services at the same priority, determine the priority order of the corresponding running recording services from high to low in the order of increasing the number of cameras currently starting video recording.

[0102] Exemplarily, the statistical information obtained by the edge gateway node is shown in Table 1:

[0103]

[0104] For the recording services encoded as record001-003 during operation, it is determined that the priority of record001-002 with a CPU usage rate of 20% is the highest. Then, since the memory usage rates are the same, record002 with 8 cameras currently starting video recording is selected, and the recording task is assigned to record002.

[0105] It should be noted that when selecting a recording service to assign a recording task, since the number of cameras that the recording task may need to start is very large, and the number of cameras started by the currently selected recording service reaches the maximum but still cannot fully execute the recording, at this time, the recording task assignment can be executed again according to the above mechanism until all recording tasks are assigned to the recording service.

[0106] In the embodiment of the present application, the edge network node determines the recording service that executes the recording task, and is further used for: when all the remaining resources of the recording services during operation are occupied and there are unassigned recording tasks, determining that there is an unstarted recording service according to the pre-configured number of recording services and the number of the recording services during operation, starting a new recording service; and assigning the unassigned recording tasks to the new recording service.

[0107] In the embodiment of the present application, the edge network node uploads the obtained recorded video file to the central cloud storage server, including: cutting the obtained recorded video file into sub-files of a set file size in real time; encrypting the sub-files and uploading them to the central cloud storage server, which can ensure the security of data transmission.

[0108] The overall process of recording and playing the recorded video in the recording video recording and playing system of the present application is given below in conjunction with the accompanying drawings, as Figure 3 shown, including:

[0109] Step 301, the central cloud storage server formulates a recording plan and sends it to the edge network node;

[0110] Step 302, the edge network node receives the recording plan;

[0111] Step 303, if it is determined that the recording plan has been executed before, the recording ends; if it is determined that it has not been executed before, step 304 is executed;

[0112] Step 304, determine the recording task according to the recording plan, and assign the recording task to the currently started recording service according to the above implementation manner;

[0113] Step 305, determine whether all the remaining resources of the recording services during operation are used. If so, step 306 is executed; otherwise, step 307 is executed;

[0114] Step 306: Determine whether there is any unstarted recording service according to the configured number of recording services. If so, execute Step 307; otherwise, execute Step 3011;

[0115] Step 307: Assign the recording task to the currently available recording service;

[0116] Step 308: Determine whether the recording service has completed the recording task. If so, end; otherwise, execute Step 309;

[0117] Step 309: The edge gateway node cuts the video file recorded by the recording service into small files and uploads them back to the central cloud storage server;

[0118] Step 310: End when it is detected that all the recorded videos have been uploaded back;

[0119] Step 311: Report to the central cloud storage server that there are no resources to execute the recording task, and end the entire upload process.

[0120] The recording and playing system for recorded videos provided by the embodiments of the present application supports cross-regional historical video recording of cameras; does not strictly require the network structure to be a peer-to-peer network; supports full-terminal playback on web pages, Android terminals, and iOS; supports functions such as fast forward, slow motion, and jump of historical videos; based on streaming media forwarding, breaks through the limit on the number of concurrent viewers of historical videos; is fully cloud-developed, and all services support cloud deployment; supports horizontal expansion and can access a large number of video devices; supports the failure of the central storage cloud and ensures that historical videos are not lost within 24 hours; strictly follows the requirements of Internet transmission security, has a registration verification mechanism when accessing at the edge node, and the transmitted content is encrypted by a built-in private encryption algorithm during cross-network transmission.
