Technical Field

[0001] This disclosure relates to the field of video surveillance, and in particular to a unified device access method, apparatus, and system. Background Technology

[0002] With the proposal, promotion, and application of the GB / T28181 general standard protocol, the protocol for front-end device access to the platform has been unified and standardized. This has placed higher demands on the unified access and management methods for the massive number of front-end national standard hardware devices in video surveillance platforms. Traditionally, access to front-end national standard hardware devices involves configuring the corresponding national standard platform information address in the front-end national standard hardware device, thereby enabling cascading registration between the front-end national standard hardware device and the national standard platform.

[0003] However, as the standardization of front-end devices accelerates, a large number of devices are being built, configured, and connected to video surveillance platforms using national standard protocols. For national standard protocols and various front-end devices, once the national standard platform is configured on their respective front-end devices, any modifications to the front-end national standard platform or registration information require logging into the front-end device again. Furthermore, the national standard protocol does not support the function of redirecting the registration of front-end national standard devices. Summary of the Invention

[0031] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0032] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0033] Figure 1 This is a flowchart illustrating some embodiments of the unified device access method disclosed herein.

[0034] In step 110, the GB front-end device access cluster unit receives the GB signaling of each front-end device sent by the first LVS (Linux Virtual Server).

[0035] In some embodiments, the front-end device is a national standard front-end device, such as a camera, an NVR (Network Video Recorder), etc.

[0036] In some embodiments, the front-end device sends a national standard request signaling data packet to the first LVS, which includes an access platform request message. After receiving the access platform request message, the first LVS rewrites the MAC address of the request message using VS / DR (a method for implementing virtual servers through direct routing) and sends the front-end device's request signaling to each real server in the national standard front-end device access cluster unit.

[0037] In some embodiments, the first LVS uses any one of eight load balancing algorithms through the IPVS (IP Virtual Server) scheduler to perform load balancing on the signaling data packets sent by the massive number of front-end national standard devices it accesses.

[0038] In the IPVS scheduler, eight load balancing algorithms are listed in Table 1 below:

[0039]

[0040]

[0041] Table 1

[0042] In some embodiments, the first LVS uses the WRR algorithm to forward the national standard signaling request messages sent from the scheduling server to each real server, and increases the weight of the algorithm for real servers with excellent performance configuration.

[0043] In some embodiments, after the national standard front-end device access cluster unit receives the national standard signaling forwarded by the first LVS, it performs preliminary processing on the national standard signaling, adds the corresponding data packet source address information to distinguish the national standard request type, and sends the national standard signaling to the data processing unit.

[0044] In step 120, the data processing unit parses the national standard signaling, obtains the national standard data information of each front-end device, and verifies the national standard data information in the data storage center to obtain the verification result.

[0045] In some embodiments, the data processing unit performs protocol parsing on the national standard signaling, determines the signaling content and function based on the parsed national standard data information, and verifies it against the basic data information stored in the data storage center. For example, by analyzing the request data content, it obtains important information fields in the national standard protocol request and verifies the national standard protocol request information against the data storage center.

[0046] In some embodiments, if the national standard data information is a national standard registration request, the data processing unit performs registration and authentication of the front-end device in the data storage center and determines the authentication information content of the front-end device. If the national standard data information is a front-end device status change notification request, the data processing unit authenticates the front-end device in the data storage center and then generates a front-end device location status change message.

[0047] In some embodiments, after the data processing unit has completed the verification of the national standard data information in the data storage center and confirmed that the content is correct, it sends a national standard response request to the national standard front-end device access cluster unit.

[0048] In step 130, the national standard front-end device access cluster unit constructs a verification result data packet with the unified access address information of the front-end device as the source address based on the IP address and interface of the first LVS, and sends the verification result data packet to the corresponding front-end device so that the corresponding front-end device can access the upper-level national standard platform based on the unified access address information of the front-end device in the verification result data packet.

[0049] In some embodiments, after receiving the national standard response request signaling sent by the data processing unit, the national standard front-end device access cluster unit constructs a national standard protocol response data packet based on the source address information carried in the data packet and the IP address and interface of the first LVS, and sends the response signaling to the front-end device with the IP address and interface of the first LVS as the source address.

[0050] In the above embodiments, multiple front-end devices use the IP address and interface of the first LVS as the source address to access the national standard platform. Even if the registration information of the national standard platform or the front-end devices is modified, there is no need to log in to the front-end devices again to modify the address, thus achieving unified access for a massive number of front-end devices.

[0051] Figure 2 The following are schematic flowcharts illustrating other embodiments of the unified device access method disclosed herein.

[0052] In step 210, the data storage center generates a front-end device redirection task.

[0053] In some embodiments, the data storage center constructs a corresponding front-end device redirection task and generates a corresponding front-end device redirection message.

[0054] In step 220, after the data processing unit extracts and verifies the key data in the front-end device redirection task, it sends the front-end device redirection task to the national standard device redirection cluster unit.

[0055] In some embodiments, the data processing unit receives front-end device redirection tasks established by the data storage center by subscribing to redirection task messages, extracts the corresponding key data in the redirection task and verifies the accuracy of the task, and then sends the information to the national standard device redirection cluster unit.

[0056] In step 230, the national standard device redirection cluster unit constructs a front-end device redirection message with the unified platform interface address information as the source address based on the IP address and interface of the second LVS.

[0057] In some embodiments, the national standard device redirection cluster unit, through the national standard front-end device redirection information task obtained from the data processing unit, constructs a national standard redirection processing request signaling with the IP address and interface of the second LVS as the source address, and sends a front-end device registration redirection request to the superior national standard platform.

[0058] In step 240, the national standard equipment redirection cluster unit sends a front-end equipment redirection message to the upper-level national standard platform so that the upper-level national standard platform can verify the front-end equipment redirection message.

[0059] In some embodiments, the national standard equipment redirection cluster unit generates a national standard registration package and pushes the device location to the upper-level national standard platform based on the IP address and interface of the second LVS.

[0060] In some embodiments, after receiving a national standard registration request, the superior national standard platform sends a verified response to the platform through the unified platform interface address provided by the system.

[0061] In some embodiments, the national standard equipment redirection cluster unit, based on the response from the superior national standard platform to this system, replies the response result to the data processing unit for database processing, authenticates and authorizes successful response messages, saves them as data, and issues alarm prompts for failed response results.

[0062] In other embodiments of this disclosure, the national standard equipment redirection cluster unit receives the response signaling from the upper-level national standard platform sent by the second LVS. The data processing unit parses the response signaling to obtain the national standard data information of the upper-level national standard platform. The data storage center generates an upper-level national standard platform request message based on the national standard data information of the upper-level national standard platform, and the data processing unit processes the upper-level national standard platform request message. For example, the data processing unit subscribes to the national standard commands of the upper-level national standard platform in the consumption data center, parses the corresponding point information of the command, and sends the processing result to the national standard front-end equipment access cluster unit.

[0063] In the above embodiments, when the front-end device is redirected, after the platform parameters are configured, there is no need to modify the parameters again. Instead, the platform side performs adaptive adaptation to realize the secondary redirection function of the front-end device, providing a more flexible mechanism for subsequent business function development and scheduling management.

[0064] Figure 3 The following are schematic flowcharts illustrating other embodiments of the unified device access method disclosed herein.

[0065] In step 310, the second LVS sends the control command issued by the superior national standard platform to the optimal national standard device redirection unit in the national standard device redirection cluster unit.

[0066] In some embodiments, the second LVS receives video requests, directory queries, PTZ control and other related control commands from the superior national standard platform, and schedules and distributes them to the most suitable national standard device redirection unit through the LVS service algorithm.

[0067] In step 320, the national standard equipment redirection unit forwards the control command to the data processing unit so that the data processing unit can parse the control command.

[0068] In step 330, the data processing unit generates a task message according to the control command and sends the task message to the data storage center for task allocation.

[0069] In some embodiments, after parsing the control command, the data processing unit matches and verifies the parsed command in the data storage center, generates a corresponding task message, and pushes the task message to the data storage center for task allocation.

[0070] In step 340, after receiving the task message, the data processing unit sends the task message to the optimal national standard front-end device access unit in the national standard front-end device access cluster unit.

[0071] In some embodiments, when an idle data processing unit receives a task push, it consumes the message and forwards the message content to one of the national standard front-end device access cluster units. The optimal national standard front-end device access unit is, for example, an idle national standard front-end device access unit.

[0072] In step 350, the national standard front-end device access unit constructs a control command request packet using the unified access address information of the front-end device as the source address, and sends the control command request packet to the front-end device so that the front-end device can respond to the national standard front-end device access cluster unit through the first LVS according to the unified access address information of the front-end device.

[0073] The national standard front-end device access unit receives the task information sent by the data processing unit. Based on the corresponding address and task information carried in the task, it constructs a national standard request protocol packet and sends the request protocol to the front-end device using the unified access address information, thus completing the request command issuance. The front-end device then sends a response command packet to the first LVS based on the unified access address information, and the first LVS forwards it back to the national standard front-end device cluster access unit.

[0074] In the above embodiments, the redirection registration function of the front-end device is implemented, thereby enabling it to receive real-time video requests, video playback requests, directory queries, point status subscriptions and other related national standard signaling sent by the superior national standard video surveillance platform.

[0075] Figure 4 This is a schematic diagram of the structure of some embodiments of the unified device access device disclosed herein. The system includes a first LVS 410, a national standard front-end device access cluster unit 420, a data processing unit 430, and a data storage center 440.

[0076] The first LVS 410 is configured to receive national standard signaling from each front-end device.

[0077] The first LVS 410 uses a direct routing method to implement virtual servers, rewriting the MAC address of the national standard signaling of each front-end device, and sending the national standard signaling to each real server that has deployed the national standard front-end device access cluster unit.

[0078] The GB standard front-end device access cluster unit 420 is configured to receive GB standard signaling from each front-end device sent by the first LVS, and to construct a verification result data packet with the unified access address information of the front-end device as the source address according to the IP address and interface of the first LVS, and send the verification result data packet to the corresponding front-end device so that the corresponding front-end device can access the upper-level GB standard platform according to the unified access address information of the front-end device in the verification result data packet.

[0079] In some embodiments, the national standard front-end device access cluster unit 420 is deployed on the Real Server configured on the first LVS 410 to receive signaling data packets forwarded by the Load Balancer.

[0080] The data processing unit 430 is configured to parse the national standard signaling and obtain the national standard data information of each front-end device.

[0081] In some embodiments, the data processing unit 430 determines the corresponding national standard protocol process based on the parsed content. If the national standard data information is a national standard registration request, the data processing unit performs registration and authentication of the front-end device in the data storage center and determines the authentication information content of the front-end device; if the national standard data information is a front-end device status change notification request, the data processing unit authenticates the front-end device in the data storage center and generates a front-end device location status change message.

[0082] Data storage center 440 is configured to verify national standard data information and obtain verification results.

[0083] In some embodiments, the data storage center 306 can be used to store three main types of data: static data, dynamic cached data, and task message data. Static data stores basic information about the front-end device's location, basic information about the upper-level national standard platform, and an authorized location information table from the upper-level national standard platform. This static data is used for verification during the registration and authentication process of the upper-level national standard platform and the front-end national standard device. The authorized location table is used to assign location ownership during front-end device redirection. Dynamic data stores cached authorization information for front-end device registration and authentication, cached status rows for front-end device locations, and cached authorization information for the upper-level national standard platform registration and authentication, including location status information. Task message data is used to push task messages.

[0084] In some embodiments, the data storage center 440 is used to store static basic data to provide basic information data for front-end devices to access the cluster unit, to provide dynamic cache data for the registration and authentication of front-end national standard devices, and to store point status information, etc.

[0085] In the above embodiments, multiple front-end devices use the IP address and interface of the first LVS as the source address to access the national standard platform, thereby enabling unified access for a massive number of front-end devices.

[0086] Figure 5 The diagram shows the structure of some other embodiments of the unified device access apparatus disclosed herein. The apparatus also includes a national standard device redirection cluster unit 510 and a second LVS 520.

[0087] Data storage center 440 is configured to generate front-end device redirection tasks.

[0088] In some embodiments, the data storage center 440 performs message subscription and push data information to redirect national standard signaling, and provides basic information data to the national standard equipment redirection cluster unit.

[0089] The data processing unit 430 is configured to extract and verify the key data in the front-end device redirection task, and then send the front-end device redirection task to the national standard device redirection cluster unit.

[0090] The data processing unit 430 generates a corresponding point status change message and sends the message to the data storage center 440. The data storage center 440 then broadcasts the corresponding message to all national standard equipment redirection cluster units 510.

[0091] The national standard device redirection cluster unit 510 is configured to construct a front-end device redirection message with the unified platform interface address information as the source address based on the IP address and interface of the second LVS, and send the front-end device redirection message to the upper-level national standard platform so that the upper-level national standard platform can verify the front-end device redirection message.

[0092] In some embodiments, the national standard equipment redirection cluster unit 510 receives the response signaling from the upper-level national standard platform sent by the second LVS 520; the data processing unit 430 parses the response signaling to obtain the national standard data information of the upper-level national standard platform; the data storage center 440 generates a request message from the upper-level national standard platform based on the national standard data information of the upper-level national standard platform; and the data processing unit 430 processes the request message from the upper-level national standard platform.

[0093] In other embodiments of this disclosure, the second LVS 520 sends control commands issued by the upper-level national standard platform to the optimal national standard device redirection unit 510 in the national standard device redirection cluster unit; the national standard device redirection unit 510 forwards the control commands to the data processing unit 430 so that the data processing unit 430 can parse the control commands; the data processing unit 430 generates a task message according to the control commands and sends the task message to the data storage center 440 for task allocation, and after receiving the task message, sends the task message to the optimal national standard front-end device access unit in the national standard front-end device access cluster unit 420; the national standard front-end device access unit 420 constructs a control command request packet using the unified access address information of the front-end device as the source address, and sends the control command request packet to the front-end device so that the front-end device can respond to the national standard front-end device access cluster unit through the first LVS according to the unified access address information of the front-end device.

[0094] In the above embodiments, when the front-end device is redirected, after the platform parameters are configured, there is no need to modify the parameters again. Instead, the platform side performs adaptive adaptation to realize the secondary redirection function of the front-end device, providing a more flexible mechanism for subsequent business function development and scheduling management.

[0097] In this embodiment, data instructions are stored in the memory and then processed by the processor, enabling a large number of national standard devices to access the upper-level national standard platform using the same access address. Furthermore, when the front-end device is redirected, after the platform parameters are configured, no secondary modification of the parameters is required. The platform side performs adaptive adaptation, realizing the secondary redirection function of the front-end device. This provides a more flexible mechanism for subsequent business function development and scheduling management, and opens up more possibilities for future business functions.
