Description

Technical Field

[0001] This disclosure relates to the field of vehicle control technology, and in particular to a vehicle-road-cloud integrated networking system, method, device and computer medium. Background Technology

[0002] With the rapid development of intelligent connected vehicles and smart transportation systems, traditional single-vehicle intelligence models face significant bottlenecks in terms of safety, collaborative efficiency, and large-scale deployment. Vehicle-road-cloud integration, as a new type of intelligent transportation system, achieves global perception and collaborative decision-making through deep collaboration between vehicles, road infrastructure, and cloud platforms, becoming a key path to overcome the limitations of single-vehicle intelligence. However, existing technological solutions still have many core issues hindering large-scale commercialization.

[0003] While existing centralized architectures (such as Baidu Apollo Cloud 2.0) handle over 80% of computing tasks in the cloud, they suffer from high system complexity, difficulties in three-level clock synchronization, insufficient interoperability between cross-vendor devices (industry interface standardization rate is only 65%), and long engineering implementation cycles (6-12 months). Layered collaborative architectures, while emphasizing modularity, suffer from high latency in cross-layer collaboration and drastic performance drops in weak network environments. Furthermore, existing solutions fail to effectively integrate the advantages of 5G and C-V2X technologies, lack compatibility with domestically produced chips, roadside equipment, and cloud control platforms, and have weak data security and link redundancy mechanisms, making it difficult to support large-scale commercial use.

[0004] Therefore, there is an urgent need to build an efficient, stable, secure and scalable communication network to meet the stringent requirements of real-time data interaction and collaborative decision-making for intelligent connected vehicles. Summary of the Invention

[0005] This disclosure aims to solve at least one of the technical problems existing in the prior art, and proposes a vehicle-road-cloud integrated networking system, method, device and computer medium.

[0006] In a first aspect, the present disclosure provides a vehicle-road-cloud integrated converged networking system, including a communication convergence module, a hierarchical networking module, a cloud collaboration module, and a redundant link module;

[0007] The communication fusion module is configured to perform data transmission based on the fusion of fifth-generation mobile communication network and cellular vehicle-to-everything (V2X) direct communication technology.

[0008] The hierarchical networking module includes access layer switching devices, aggregation layer switching devices, and core layer switching devices. The access layer switching devices are deployed at road junctions, the aggregation layer switching devices are used for ring networking, and the core layer switching devices are connected to edge cloud servers.

[0009] The cloud collaboration module connects to the remote cloud server through the firewall device at the exit of the core layer switching device, enabling collaborative interaction between the edge cloud server and the remote cloud server.

[0010] The redundant link module is configured as a wired backhaul link and a wireless backhaul link, with the wireless backhaul link serving as a backup channel for the wired backhaul link.

[0011] In some embodiments, the aggregation layer switching equipment and the access layer switching equipment form an optical fiber ring network, and the optical fiber ring network constructs multiple road junctions into a ring topology according to the principle of geographical proximity.

[0012] The aggregation layer switching equipment is connected to the core layer switching equipment via dual physical links;

[0013] The edge cloud server is deployed on the local network side of the core layer switching equipment.

[0014] In some embodiments, when the road intersection is a four-way intersection, the hierarchical networking module includes four access layer switching devices and one aggregation layer switching device. The access layer switching devices and the aggregation layer switching device are connected through a first deployment method, which is:

[0015] Four access layer switching devices are deployed in the four directions of traffic at the road junction, and the input of each access layer switching device is connected to the aggregation layer switching device in the corresponding direction.

[0019] In some embodiments, when the road junction is a crossroads, the hierarchical networking module includes four intelligent sensing devices, one access layer switching device, and one aggregation layer switching device. The access layer switching device and the aggregation layer switching device are connected through a second deployment method, which is as follows:

[0020] The access layer switching equipment and the aggregation layer switching equipment are respectively deployed in two diagonal directions of the intersection;

[0021] The output of each intelligent sensing device can be connected to the input of either the access layer switching device or the aggregation layer switching device.

[0022] The intelligent sensing device is equipped with photoelectric converters at its outlet and at the inlet of the corresponding switching device.

[0023] The core layer switching equipment is deployed in the computer room, and the output terminals of the core layer switching equipment are connected to the edge cloud server and the remote cloud server, respectively.

[0024] In some embodiments, the wireless backhaul link includes fifth-generation mobile communication client terminal equipment deployed at at least two road intersections. The fifth-generation mobile communication client terminal equipment accesses a remote cloud server through the fifth-generation mobile communication public network and automatically carries the data stream when the wired backhaul link fails.

[0025] In some embodiments, the redundant link module employs a multi-level heterogeneous redundancy mechanism:

[0026] Link-level redundancy is achieved through wired and wireless backhaul links; device-level redundancy is achieved through dual-link physical channels from aggregation layer switching equipment to core layer switching equipment; and network-level redundancy is achieved through at least two mutually backup dedicated data lines connecting firewall equipment to remote cloud servers.

[0027] In some embodiments, the edge cloud server includes a computing unit and a storage unit for processing real-time business within a preset geographical range and caching data;

[0028] The remote cloud server is used for non-real-time in-depth analysis;

[0029] The system distributes data to edge cloud servers or remote cloud servers based on the time-sensitive identifier of the task, thereby enabling edge-cloud collaborative computing.

[0030] Secondly, embodiments of this disclosure provide a vehicle-road-cloud integrated networking method, applied to the vehicle-road-cloud integrated networking system described in the first aspect, comprising:

[0031] The communication fusion module establishes a converged data transmission channel between the fifth-generation mobile communication network and the cellular vehicle-to-everything (V2X) direct communication technology.

[0032] The layered networking module is used to deploy access layer, aggregation layer and core layer switching equipment to build a ring network topology covering road intersections and connect to edge cloud servers;

[0033] Configure the firewall device through the cloud collaboration module to establish a collaborative interaction link between the edge cloud server and the remote cloud server;

[0034] Based on the redundant link module, deploy wired and wireless backhaul links, and set the wireless backhaul link as a backup channel for the wired backhaul link to complete the network construction.

[0035] In some embodiments, the deployment of access layer, aggregation layer, and core layer switching devices using the hierarchical networking module to construct a ring network topology covering road junctions includes:

[0036] The access layer switching equipment at multiple road junctions is divided into logical groups based on the principle of geographical proximity;

[0037] The access layer switching equipment in each group is interconnected with the corresponding aggregation layer switching equipment through optical fiber media to form an optical fiber ring network;

[0038] Configure dual physical links for the aggregation layer switching device to connect it to the core layer switching device, and establish a communication connection between the core layer switching device and the edge cloud server.

[0039] In some embodiments, the deployment of wired backhaul links and wireless backhaul links based on the redundant link module includes:

[0040] In each road junction corresponding to a ring network topology, select at least two junctions to deploy fifth-generation mobile communication client terminal equipment;

[0041] Configure fifth-generation mobile communication client terminal equipment to access the fifth-generation mobile communication public network to form a wireless backhaul link;

[0042] Configure link monitoring rules to trigger a data stream switch from the wired backhaul link to the wireless backhaul link when the transmission parameters of the wired backhaul link exceed the preset normal range.

[0043] Thirdly, embodiments of this disclosure provide an electronic device, including:

[0044] One or more processors;

[0045] Memory, used to store one or more programs;

[0046] When one or more programs are executed by one or more processors, the one or more processors implement the vehicle-road-cloud integrated networking method provided in the second aspect.

[0047] Fourthly, embodiments of this disclosure provide a computer-readable medium storing a computer program, which, when executed by a processor, implements the vehicle-road-cloud integrated networking method provided in the second aspect.

[0048] The vehicle-road-cloud integrated networking system disclosed herein includes a communication fusion module, a hierarchical networking module, a cloud collaboration module, and a redundant link module. These modules work collaboratively, and are equipped with link switching methods, electronic devices, and computer-readable media to form a complete technical solution. Specifically, since 5G provides wide-area coverage, high bandwidth, and ultra-low latency cellular access capabilities, while C-V2X direct communication mode enables rapid vehicle-to-vehicle and vehicle-to-road information broadcasting in scenarios without base station coverage, the communication fusion module uses the integration of 5G and C-V2X technologies for data transmission. The two technologies complement each other and can adapt to diverse communication needs in complex traffic environments. The hierarchical networking module includes access layer, aggregation layer, and core layer switching equipment. The access layer is deployed at road junctions, the aggregation layer is used for ring networking, and the core layer connects to edge cloud servers. This three-layer architecture reduces network management complexity through layered decoupling, avoids the clock synchronization problems of centralized architectures, and allows for focused functionality at each layer, facilitating the definition and implementation of standardized interfaces. The cloud collaboration module connects to remote cloud servers through the core layer egress firewall, enabling collaborative interaction between the edge and remote clouds. This allows high-real-time-requirement localized services to be offloaded to the edge cloud for processing, while non-real-time in-depth analysis is handled by the remote cloud, thus balancing response speed and computing resource consumption. The redundant link module configures both wired and wireless backhaul links, with the wireless link serving as a backup for the wired link. This addresses the risk of service interruption due to a single link failure by improving network availability through heterogeneous link backup. Attached Figure Description

These should be considered merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0055] Where there is no conflict, the various embodiments of this disclosure and the features thereof in the embodiments may be combined with each other.

[0056] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.

[0057] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure.

[0058] Unless otherwise specified, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted as having an idealized or overly formal meaning, unless expressly so defined herein.

[0059] The collection, storage, use, processing, transmission, provision, and disclosure of user personal information in this technical solution comply with relevant laws and regulations and do not violate public order and good morals. The use of user data in this technical solution follows relevant national laws and regulations (e.g., the "Information Security Technology - Personal Information Security Specification"). For example, appropriate measures are taken for personal information access control; restrictions are imposed on the display of personal information; the purpose of using personal information does not exceed the scope of direct or reasonable association; and explicit identity targeting is eliminated when using personal information to avoid precisely identifying specific individuals.

[0060] With the rapid development of intelligent connected vehicles and smart transportation systems, traditional single-vehicle intelligence models face significant challenges in terms of safety, collaborative efficiency, and large-scale deployment. Vehicle-road-cloud integration, as a new type of intelligent transportation system, achieves more efficient and safer autonomous driving and intelligent traffic management through deep collaboration between vehicles, road infrastructure, and cloud platforms. Its core value lies in breaking through the bottleneck of single-vehicle intelligence and optimizing transportation system performance through "global perception + collaborative decision-making."

[0061] Current solutions for integrated vehicle-road-cloud (V2X) systems have several shortcomings. Centralized architectures, exemplified by Baidu Apollo Cloud 2.0, employ a centralized cloud processing model, with roadside devices acting only as data collection nodes, and vehicles interacting with the cloud via 4G / 5G networks. This architecture requires resolving three-level clock synchronization issues, exhibits significant bottlenecks in cross-vendor device interoperability (industry interface standardization rate is only 65%), and suffers from long implementation cycles. Typical demonstration areas require 6-12 months from solution design to formal operation, with joint debugging and testing alone taking 3-4 months, severely hindering large-scale deployment.

[0062] Another type of existing layered collaborative architecture, while emphasizing standardization and modular expansion, is divided into a perception layer, a network layer, a platform layer, and an application layer. However, it is prone to cross-layer collaboration delays, such as slow cloud decision feedback, and is highly dependent on network reliability. Its performance will drop significantly in weak network environments.

[0063] Furthermore, integrated vehicle-road-cloud networking needs to simultaneously meet the hybrid requirements of cellular and direct communication. Existing solutions fail to effectively integrate the advantages of 5G and C-V2X technologies, resulting in insufficient communication timeliness, reliability, flexibility, and scalability. The network architecture design lacks ecosystem adaptation for domestically produced chips, roadside equipment, and cloud control platforms, and data security and link redundancy mechanisms are also inadequate, making it unable to support large-scale commercial applications in high-value scenarios such as commercial vehicle logistics and urban intelligent traffic control.

[0064] To address the shortcomings of existing technologies and meet the requirements of vehicle-road-cloud integrated networking for timeliness, reliability, integrity, advanced technology, high performance, open standards, flexibility, and scalability, this disclosure proposes a vehicle-road-cloud integrated converged networking system. This system deeply integrates 5G and C-V2X technologies, adopts a hierarchical ring network topology and a multi-level heterogeneous redundancy mechanism, and solves key problems such as synchronization complexity, interoperability bottlenecks, and long deployment cycles of traditional architectures. At the same time, it realizes intelligent switching between wired and wireless links to ensure service continuity.

[0065] The vehicle-road-cloud integrated networking system provided in this disclosure includes a communication fusion module, a hierarchical networking module, a cloud collaboration module, and a redundant link module, wherein:

[0066] The communication convergence module is configured to perform data transmission based on the convergence of fifth-generation mobile communication network (5G) and cellular vehicle-to-everything (C-V2X) direct communication technology.

[0067] Figure 1 This is a schematic diagram of the hierarchical networking module provided in an embodiment of this disclosure. The diagram clearly shows the three-layer progressive relationship of the access layer switching equipment, the aggregation layer switching equipment, and the core layer switching equipment, as well as the parallel architecture of the wired ring network and the 5G wireless backup link. Figure 1 As shown, the hierarchical networking module includes access layer switching equipment, aggregation layer switching equipment and core layer switching equipment. The access layer switching equipment is deployed at road junctions, the aggregation layer switching equipment is used for ring networking, and the core layer switching equipment is connected to the edge cloud server.

[0068] The cloud collaboration module connects to the remote cloud server through the firewall device at the exit of the core layer switching device, enabling collaborative interaction between the edge cloud server and the remote cloud server.

[0069] The redundant link module is configured as a wired backhaul link and a wireless backhaul link, with the wireless backhaul link serving as a backup channel for the wired backhaul link.

[0070] The vehicle-road-cloud integrated networking system provided in this disclosure includes a communication fusion module, a hierarchical networking module, a cloud collaboration module, and a redundant link module. These modules work collaboratively, and are equipped with link switching methods, electronic devices, and computer-readable media to form a complete technical solution. Specifically, since 5G provides wide-area coverage, high bandwidth, and ultra-low latency cellular access capabilities, while C-V2X direct communication mode enables rapid vehicle-to-vehicle and vehicle-to-road information broadcasting in scenarios without base station coverage, the communication fusion module performs data transmission based on the integration of 5G and C-V2X technologies. The two complement each other and can adapt to diverse communication needs in complex traffic environments. The hierarchical networking module includes access layer, aggregation layer, and core layer switching equipment. The access layer is deployed at road junctions, the aggregation layer is used for ring networking, and the core layer connects to edge cloud servers. This three-layer architecture reduces network management complexity through layered decoupling, avoids the clock synchronization problems of centralized architectures, and allows for focused functionality at each layer, facilitating the definition and implementation of standardized interfaces. The cloud collaboration module connects to remote cloud servers through the core layer egress firewall, enabling collaborative interaction between the edge and remote clouds. This allows high-real-time-requirement localized services to be offloaded to the edge cloud for processing, while non-real-time in-depth analysis is handled by the remote cloud, thus balancing response speed and computing resource consumption. The redundant link module configures both wired and wireless backhaul links, with the wireless link serving as a backup for the wired link. This addresses the risk of service interruption due to a single link failure by improving network availability through heterogeneous link backup.

[0071] In some embodiments, the aggregation layer switching equipment and the access layer switching equipment form a fiber optic ring network, and the fiber optic ring network constructs multiple road junctions into a ring topology according to the principle of geographical proximity; the aggregation layer switching equipment is connected to the core layer switching equipment through dual physical links; the edge cloud server is deployed on the local network side of the core layer switching equipment.

[0072] Furthermore, this embodiment defines an optical fiber ring network as the aggregation layer and access layer, and constructs multiple road intersections into a ring topology based on geographical proximity. The use of an optical fiber ring network instead of traditional star or chain topologies is advantageous because the ring network structure can automatically switch to a different route in case of a single-point link failure, improving link-level reliability. Simultaneously, optical fiber offers advantages such as high bandwidth, resistance to electromagnetic interference, and long transmission distance, meeting the long-term stable transmission requirements of high-volume data such as high-definition video and LiDAR point clouds. The aggregation layer is connected to the core layer via dual physical links, achieving device-level redundancy. Even if one uplink link fails, services can still be forwarded via the backup link, avoiding single-point failure. Edge cloud servers are deployed on the local network side of the core layer switching equipment, minimizing data transmission paths, reducing end-to-end latency, and ensuring real-time collaborative decision-making at intersections.

[0073] In some embodiments, when the road intersection is a four-way intersection, the hierarchical networking module includes four access layer switching devices and one aggregation layer switching device. The access layer switching devices and the aggregation layer switching device are connected through a first deployment method, which is:

[0074] Four access layer switching devices are deployed in the four directions of traffic at the road junction, with the input of each access layer switching device connected to the aggregation layer switching device in the corresponding direction; the output of the four access layer switching devices is connected to the input of one aggregation layer switching device, forming the optical fiber ring network; the output of the aggregation layer switching device is connected to the core layer switching device through dual links; the optical fiber ring network is a GE ring or a dual GE ring.

[0075] For a four-way intersection scenario, this disclosure proposes a first deployment method for the access layer and aggregation layer. Specifically, one access switch is deployed in each direction of traffic, forming an access fiber optic ring network with the aggregation layer switch. Roadside computing units are connected to the aggregation layer switch. This first deployment method corresponds to a "4+1" intersection networking scheme. "4" represents the four directions of the four-way intersection, with one access switch deployed in each direction to handle access to roadside devices within a single point (pole) location. These access switches connect to cameras, millimeter-wave radar, lidar, etc. "1" represents the intersection aggregation switch. Multiple access switches and one aggregation switch at the four-way intersection form an access fiber optic ring network, and roadside edge computing devices are connected to the aggregation switch on the ring network.

[0076] Figure 2This is a structural diagram illustrating a deployment method for access layer switching equipment and aggregation layer switching equipment provided in an embodiment of this disclosure, as shown below. Figure 2 As shown, the access switch deploys two optical fibers towards the adjacent access switching equipment at this intersection for interconnection between access devices. If the distance between intersections is short, Category 6 or higher network cables can also be used for interconnection, but optical fiber is recommended to meet the needs of long distance, adjustable bandwidth capacity, and long service life. A GE ring network is recommended. If traffic demand is high, it can be expanded to a dual GE ring network. When it is not possible to form a fiber optic ring network, a chain or star topology should be considered. The aggregation switch connects to the core switch via dual links (self-built).

[0077] from Figure 2 As can be seen, the access switches in the four directions are connected end-to-end via optical fibers to form a ring network, with the aggregation switch serving as a key node in the ring network, mounting roadside edge computing devices. Each direction has an independent access switch, preventing a single device failure from paralyzing the entire intersection's services. The access switches are interconnected via optical fibers to form a ring, allowing data from any direction to travel bidirectionally to the aggregation layer, improving topology robustness. Roadside computing units (such as edge computing servers) are mounted on the aggregation switches rather than the access layer. This is because the aggregation layer is located at the ring network hub, facilitating the unified processing and distribution of data from multiple directions, reducing redundant deployment of computing resources, and allowing for future expansion to a dual GE ring to meet greater traffic demands.

[0078] In some embodiments, when the road junction is a crossroads, the hierarchical networking module includes four intelligent sensing devices, one access layer switching device, and one aggregation layer switching device. The access layer switching device and the aggregation layer switching device are connected through a second deployment method, which is as follows:

[0079] The access layer switching equipment and the aggregation layer switching equipment are respectively deployed in two diagonal directions of the intersection; the output of each intelligent sensing device is selectively connected to the input of the access layer switching equipment or the aggregation layer switching equipment; the output of the intelligent sensing device and the entrance of the corresponding switching equipment are respectively equipped with photoelectric converters; the core layer switching equipment is deployed in the computer room, and the output of the core layer switching equipment is respectively connected to the edge cloud server and the remote cloud server.

[0080] For crossroads, this disclosure proposes a second deployment method for the access layer and aggregation layer. Specifically, the access layer switching equipment and the aggregation layer switching equipment are deployed diagonally in opposite traffic directions. Intelligent sensing devices are connected nearby via photoelectric signal conversion devices, and at some intersections, sensor data is centrally processed by an edge cloud server. This deployment method corresponds to a "1+1" intersection networking scheme, where the access layer switching equipment and the aggregation layer switching equipment are deployed only diagonally in opposite traffic directions, and intelligent sensing devices are connected nearby via photoelectric signal conversion devices.

[0081] Figure 3 This is a schematic diagram illustrating another deployment method for access layer switching equipment and aggregation layer switching equipment provided in an embodiment of this disclosure, as shown below. Figure 3 As shown, for intersections using this scheme, in a crossroads scenario, each intersection has four directions, with one AI camera (intelligent sensing device) deployed in each direction to transmit structured data from the intersection. Two diagonally opposite directions from the four intersections are each equipped with one access switch (access layer switching device) and one aggregation switch (aggregation layer switching device). The AI ​​camera in each direction is placed on either the nearest access switch or the aggregation switch, based on the actual wiring layout. Each AI camera's output and the switch's input are connected to an external photoelectric converter for data transmission. If the number of optical ports on the switch allows, the photoelectric converter can be connected at the AI ​​camera's output and then connected to the switch via fiber optic cable. A ring can be selected as a pilot intersection for local edge computing. No edge computing unit is deployed on the roadside; sensor data is uploaded to a local edge server via the network for processing, and the results are then transmitted back to the vehicle terminal via the RSU. The core switch is deployed in the server room, connecting to the local edge computing server and also to the cloud server via a local dedicated data line. This design considers that in some scenarios, no computing unit needs to be deployed on the roadside, simplifying roadside equipment deployment and reducing costs. The photoelectric signal conversion device ensures effective data transmission between different media. The second deployment method can optimize equipment deployment density, reduce the number of roadside devices and deployment costs, and achieve resource sharing through centralized processing by edge cloud servers. It provides options for flexible deployment of edge computing resources, making it easier to concentrate computing power, reduce the complexity of front-end devices, and improve data processing efficiency during the pilot phase.

[0082] In some embodiments, the wireless backhaul link includes a fifth-generation mobile communication client terminal equipment (5G CPE) deployed at at least two road junctions. The fifth-generation mobile communication client terminal equipment accesses a remote cloud server through the fifth-generation mobile communication public network and automatically carries the data stream when the wired backhaul link fails.

[0083] It should be understood that in vehicle-road-cloud integrated scenarios, roadside equipment typically relies on wired fiber optic backhaul. However, underground utility tunnel resources are limited, construction costs are high, and the risk of physical fiber optic cable breakage objectively exists. Because wireless links are flexible to deploy and quick to activate, they can serve as an emergency channel in case of wired link interruptions. Therefore, two intersections in each ring network are selected to deploy 5G CPEs as wireless backup nodes. For example... Figure 1 As shown, the 5G wireless link serves as a backup path for the wired leased line and is directly connected to the core switch. The requirement of deploying at least two intersections is to prevent the loss of wireless backup capability due to the failure of a single CPE node, thus creating simple device-level redundancy. The high bandwidth and low latency characteristics of the 5G public network enable it to carry roadside monitoring data and signaling backhaul. Although the cost is higher as the primary link, it has economic advantages as a backup. The automatic data flow carrying function is achieved through link monitoring and routing switching protocols, requiring no manual intervention and controlling service interruption time to the second or even millisecond level.

[0084] In some embodiments, the redundant link module employs a multi-level heterogeneous redundancy mechanism:

[0085] Link-level redundancy is achieved through wired and wireless backhaul links; device-level redundancy is achieved through dual-link physical channels from aggregation layer switching equipment to core layer switching equipment; and network-level redundancy is achieved through at least two mutually backup dedicated data lines connecting firewall equipment to remote cloud servers.

[0086] Furthermore, since single-level redundancy cannot fully cover the failure risks at different levels such as links, devices, and networks, while multi-level redundancy can form all-round protection, this disclosure proposes a multi-level heterogeneous redundancy mechanism, including link-level redundancy (wired + wireless), device-level redundancy (dual links converged to the core), and network-level redundancy (at least two mutually backup data dedicated lines from the firewall to the remote cloud), to build redundancy protection from the three levels of links, devices, and networks, significantly improving the system's fault resistance and overall reliability, and reducing the risk of system paralysis caused by a single link failure.

[0087] Specifically, the core value of the aforementioned heterogeneous redundancy mechanism lies in avoiding common-source failures. That is, different redundancy levels employ different types of technologies and paths to ensure that a common-cause failure at one level does not affect the entire system. At the link level, wired and wireless heterogeneity prevents the simultaneous occurrence of fiber optic cable breakage during construction and wireless signal interference. At the device level, if dual-link physical channels use different routes, simultaneous interruptions of cables in the same trench can be avoided. At the network level, if two dedicated data lines belong to different operators, failures in a single operator's backbone network can be mitigated. Deploying two dedicated data lines at the firewall egress point connects to the remote cloud, supporting public or private cloud deployment methods. Enterprises can flexibly choose according to their data security policies, and the dual dedicated lines serve as backups for each other, ensuring the continuity of cloud services.

[0088] In some embodiments, the edge cloud server includes a computing unit and a storage unit for processing real-time business within a preset geographical range and caching data; the remote cloud server is used for non-real-time in-depth analysis; the system distributes data to the edge cloud server or the remote cloud server according to the time sensitivity identifier of the task, thereby realizing edge-cloud collaborative computing.

[0089] This disclosure also defines a task division and collaboration mechanism between edge cloud servers and remote cloud servers. The edge cloud is deployed in a local data center, directly connected to the core switch, and its geographical scope typically covers one or more traffic areas. The remote cloud possesses massive storage and powerful computing capabilities, suitable for applications that are not sensitive to real-time performance, such as traffic flow prediction and driving behavior big data analysis. Task routing is achieved through time-sensitive identifiers in data packets. The edge cloud platform can be configured with policy-based routing to process data streams marked as "real-time" locally, while "non-real-time" data streams are forwarded to the remote cloud via firewalls and dedicated lines. This edge-cloud collaborative computing model ensures deterministic low latency for real-time services while fully utilizing cloud resources for deep optimization, avoiding the cost waste caused by over-configuration of edge computing power.

[0090] Based on the same inventive concept, this disclosure also provides a vehicle-road-cloud integrated networking method applicable to the above-mentioned vehicle-road-cloud integrated networking system.

[0091] Figure 4 This is a flowchart illustrating a vehicle-road-cloud integrated networking method provided in an embodiment of the present disclosure, as shown below. Figure 4 As shown, the method may specifically include steps S1-S4:

[0092] Step S1: Establish a converged data transmission channel between the fifth-generation mobile communication network and the cellular vehicle-to-everything (V2X) direct communication technology through the communication convergence module.

[0093] Step S2: Deploy access layer, aggregation layer and core layer switching equipment using the hierarchical networking module to build a ring network topology covering road intersections and connect to the edge cloud server.

[0094] Step S3: Configure the firewall device through the cloud collaboration module to establish a collaborative interaction link between the edge cloud server and the remote cloud server.

[0095] Step S4: Deploy wired and wireless backhaul links based on the redundant link module, and set the wireless backhaul link as a backup channel for the wired backhaul link to complete the network construction.

[0096] The vehicle-road-cloud integrated networking method provided in this disclosure follows the logic of communication first, topology support, collaborative interconnection, and redundancy guarantee. The communication channel is the foundation for data transmission and must prioritize the integration of 5G and C-V2X to meet the communication needs of multiple scenarios. The ring network topology optimizes link resources and improves transmission stability, serving as the core support of the network architecture. Collaborative interaction between the edge cloud and remote cloud relies on firewalls for security, preventing data leakage or external attacks. Redundant links are crucial for handling link failures and ensuring network continuity. This results in a clearly defined and functionally complementary networking scheme, ensuring that the final integrated vehicle-road-cloud network possesses both efficient communication capabilities and a stable topology with secure redundancy guarantees, avoiding networking defects caused by missing or disordered steps.

[0097] In some embodiments, step S2 above may specifically include:

[0098] Based on the principle of geographical proximity, the access layer switching equipment at multiple road intersections is divided into logical groups; the access layer switching equipment in each group is interconnected with the corresponding aggregation layer switching equipment through optical fiber media to form an optical fiber ring network; dual physical links are configured for the aggregation layer switching equipment to connect to the core layer switching equipment, and communication connections are established between the core layer switching equipment and the edge cloud server.

[0099] In some embodiments, step S4 above may specifically include:

[0100] In each road junction corresponding to the ring network topology, select at least two junctions to deploy fifth-generation mobile communication client terminal equipment; configure the fifth-generation mobile communication client terminal equipment to access the fifth-generation mobile communication public network to form a wireless backhaul link; set link monitoring rules, and when the transmission parameters of the wired backhaul link exceed the preset normal range, trigger the data flow to switch from the wired backhaul link to the wireless backhaul link.

[0101] Furthermore, in actual network deployment, this method can also be combined with the wired networking details of the hierarchical networking module: for example, when dividing the logical groups of access layer switching devices, the "4+1" or "1+1" intersection deployment scheme can be referenced simultaneously (e.g., Figure 2 , Figure 3As shown in the diagram, if the logical group contains a four-way intersection and the intersection requires local processing of real-time data, then the access layer and aggregation layer devices are deployed according to the "4+1" scheme, with the roadside computing unit mounted on the aggregation layer switching device. If the intersection does not require local computing and only needs to transmit structured data, then the diagonal devices are deployed according to the "1+1" scheme, with the AI ​​camera connected to the switch via a photoelectric converter. Simultaneously, when configuring firewall devices to establish edge cloud and remote cloud collaborative links, users can choose to connect to a public cloud or a private cloud according to their needs, and deploy at least two mutually backup dedicated data lines to form a "network-level + link-level" dual redundancy with the wireless backhaul link, further improving network reliability.

[0102] This networking method also has compatibility with system iteration and upgrade paths: in subsequent technology upgrades, if 5G evolves to 6G or C-V2X technology is updated, the convergence channel between 6G and the upgraded V2X technology can be re-established by adjusting the channel parameters of the communication convergence module; when expanding functions, if new services such as fleet management and intelligent traffic signal control are added, the network solution can be adapted to the new service requirements by optimizing the equipment configuration of the layered networking module (such as increasing the bandwidth of the core layer switching equipment) and adjusting the link monitoring rules (such as increasing the preset normal range of bandwidth utilization), without having to reconstruct the overall networking process, thus reducing upgrade costs.

[0103] In summary, the vehicle-road-cloud integrated networking system / method provided in this disclosure forms a complete system from system architecture, deployment method, link guarantee, data processing to equipment support, and has multiple technical effects. Specifically: In terms of communication performance, the integration of 5G and C-V2X achieves low latency, high bandwidth, and large-scale connectivity, meeting the data transmission needs of vehicle-road-cloud integrated multi-scenario applications; in terms of network reliability, through fiber optic ring networks, dual physical links, and multi-level heterogeneous redundancy mechanisms, connection stability is comprehensively guaranteed from the link, device, and network levels. Automatic and rapid failover is possible in case of link failure, ensuring uninterrupted service. Two intersection deployment schemes, "4+1" and "1+1," are provided to adapt to different scenarios; in terms of resource utilization, edge cloud and remote cloud collaborative computing enable real-time local processing of services and cloud-based analysis of non-real-time services, optimizing resource allocation and improving processing efficiency. Meanwhile, the cloud servers connected to the core switch can flexibly choose between public and private clouds; in terms of deployment flexibility, a wired + wireless networking mode is provided to adapt to different road intersection scenarios and deployment conditions, while also supporting subsequent technology upgrades and functional expansions, aligning with industry development trends; in terms of security, firewall devices isolate internal and external networks, and subsequent optimization strategies such as data encryption and intrusion detection ensure data transmission and system operation security. The overall solution effectively solves the problems of collaborative delay, low reliability, and difficulty in large-scale deployment in existing technologies, providing strong support for the large-scale commercial use of vehicle-road-cloud integration.
