Description

Technical Field

[0001] The present invention relates to the technical field of urban information model industry, digital twin industry, and cloud rendering message collaboration, and in particular to a method and system for distributed cloud rendering information flow collaboration based on CIM management. Background Art

[0002] In the wave of full-domain digitalization of smart cities, cloud rendering engines, as one of the key technologies, are playing an increasingly important role. However, with the acceleration of the process of urban digitalization, the message communication between cloud rendering engine flow paths faces unprecedented challenges. There are many difficulties in message communication between different flow paths (such as user terminals, data processing centers, cloud service providers, etc.), complex and changeable network environments, high synchronization delays, etc. These problems seriously restrict the effectiveness of cloud rendering engines in the full-domain digitalization of cities. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a method for distributed cloud rendering information flow collaboration based on CIM management, aiming to solve the problem that messages of different flow paths cannot be synchronized in the same three-dimensional scene.

[0004] The technical solution of the present invention is:

[0005] A method for distributed cloud rendering information flow coordination based on CIM management. This method uses the CIM platform that has been built, pushes the flow through the cloud rendering engine built on the platform, and adds a central message forwarding platform to cooperate with the front-end interface call, and adds a message synchronization mark on the interface that requires message forwarding. When the front-end interface drives the cloud rendering function, the central message forwarding platform uniformly intercepts requests with message synchronization marks, determines the three-dimensional cloud rendering scene according to the flow path, and synchronizes this message to other flow path scenes and front-end code logic callbacks in the same three-dimensional scene in the form of broadcast, so that different flow paths in the same scene can achieve the same function, and realize the efficient, real-time and accurate message synchronization capability of the three-dimensional cloud rendering scene.

[0006] Furthermore,

[0007] After several clients connect to different channels of the same 3D cloud rendering scene, the client calls the cloud rendering interface command through the front end and passes in the message synchronization identifier. The back-end central message forwarding platform intercepts the command uniformly according to the identifier and broadcasts the command to different channels of the same cloud rendering scene through the cloud rendering engine, thus achieving efficient message synchronization of the same scene under different channels.

[0008] Going further,

[0009] Client Connection

[0010] When several clients connect to the cloud rendering stream service, it is necessary to enable the message synchronization function at the initialization position of the front-end interface. One of the clients uses the front-end cloud rendering interface to initiate a function instruction, and the instruction carries a message synchronization identifier. The CIM platform will receive the connection instruction information and then store the instruction in the resource queue for caching. The resource queue follows the principle of first in, first out, and gives priority to processing the instruction that enters the queue first, waiting for the platform to perform resource comparison and resource scheduling.

[0011] Message interception

[0012] The CIM master server intercepts uniformly at the back-end central message forwarding platform according to the message identifier, filters in the resource cache according to the instruction information, and at the same time, with the help of the capabilities of the cloud rendering engine, screens out the three-dimensional cloud rendering scene service corresponding to this stream path, and at the same time performs resource comparison in the resource pool to obtain all the stream paths of the three-dimensional cloud rendering scene service in the resource pool except this instruction, and updates the message cache of this three-dimensional cloud rendering scene.

[0013] Message distribution

[0014] The central message forwarding platform sends the message to each client. The client receives the instruction and makes a callback display on the front end to provide a message prompt for development to achieve the front-end response of the corresponding function.

[0015] Message coordination

[0016] The cloud rendering engine sends the message to each stream path. The stream path receives the instruction and performs behavior disposal on the UE side to implement the instruction function, realize the function synchronization of different stream paths, and achieve the scene coordination display ability.

[0017] Client disconnection

[0018] When the client disconnects from the cloud rendering stream service, the client sends a disconnection request to the CIM master server. The central message forwarding platform intercepts, compares messages, and updates the message cache, modifies the usage status of the current stream path, and releases the occupancy and broadcast status monitoring of this stream path.

[0019] In addition, the present invention also provides a cross-stream path message synchronization system for a cloud rendering engine, including a front-end interface module, a back-end central message forwarding platform, and a UE-side cloud rendering engine, wherein:

[0020] The front-end interface module is used to receive rendering requests and information flows from different user terminals or application systems to achieve standardized message input;

[0021] The back-end central message forwarding platform is connected to the front-end interface module and the UE-side cloud rendering engine, and is responsible for receiving the messages sent by the front end, performing unified management and forwarding to ensure the accurate and real-time transmission of messages between different stream paths;

[0022] The UE-side cloud rendering engine uses the received instructions and information flow data for rendering processing and returns the rendering results to the corresponding user terminals or application systems.

[0023] Furthermore,

[0024] The backend central message forwarding platform also has the functions of network quality monitoring and adaptive adjustment, which can monitor the network conditions between different flow paths in real time and dynamically adjust the message transmission strategy accordingly.

[0025] The front-end interface module supports several communication protocols and data formats to meet the access requirements of different user terminals or application systems.

[0026] The beneficial effects of the present invention are

[0027] Currently, more and more scenarios are supported by cloud rendering. For some scenarios, the functions of different flow paths of the same scene need to be coordinated to ensure that the scene has coordination capabilities and improve the level of urban governance and urban-wide digitalization. Through this method, message coordination for different flow paths of the same scene can be achieved, enhancing the control and co-management capabilities of the CIM platform in cloud rendering, solving the problem that multi-scenario service messages in cloud rendering push services cannot be coordinated, and having application advantages in scenarios where multiple clients access the same resources.

[0035] 3) Message distribution

[0036] The message is sent to each client through the central message forwarding platform. The client receives the instruction and makes a callback display at the front end to provide a message prompt for development to achieve the front-end response of the corresponding function;

[0037] 4) Message coordination

[0038] The message is sent to each stream path through the cloud rendering engine. The stream path receives the instruction and performs behavior disposal at the UE side to implement the instruction function, realize the function synchronization of different stream paths, and achieve the ability of scene coordinated display;

[0039] 5) Client disconnection
