Description

Technical Field

[0001] The present invention relates to a long-distance V2X communication module, system and method capable of self-organizing a network, and belongs to the technical field of vehicle communication. Background Art

[0002] Traditional V2X technologies include V2V communication, V2I communication, V2N communication, and V2P communication. Among them, V2X is the abbreviation of Vehicle-to-Everything, referring to the technology for extensive communication between vehicles and the surrounding environment. V2V is the abbreviation of Vehicle-to-Vehicle, referring to vehicle-to-vehicle communication. V2V communication allows vehicles to directly communicate with each other and share real-time information such as position, speed, and direction. V2I is the abbreviation of Vehicle-to-Infrastructure, referring to vehicle-to-road equipment communication. V2I communication involves communication between vehicles and road infrastructure. V2N is the abbreviation of Vehicle-to-Network, referring to vehicle-to-network node communication. V2N communication extends the V2X communication range and allows vehicles to communicate with network nodes such as cloud servers or traffic management centers. V2P is the abbreviation of Vehicle-to-Pedestrian, referring to vehicle-to-pedestrian equipment communication. V2P communication allows vehicles to communicate with pedestrian equipment (such as smartphones).

[0003] In addition, a special communication form in V2X communication is the PC5 communication technology. PC5 is the abbreviation of Proximity Communication, referring to the technology for direct communication between devices. The PC5 communication technology involves short-distance direct communication between vehicles, people, and roads. Its steps include: sensing and recognition, where vehicles sense surrounding vehicles by carrying a PC5 communication module; spectrum allocation, where vehicles need to negotiate the use of the spectrum in the 5.9 GHz band to ensure communication reliability and interference-free; connection establishment, where once the communication spectrum is determined between vehicles, they can attempt to establish a direct connection; and communication termination, where communication terminates after data exchange between two communication nodes or when they are out of the communication range.

[0004] The PC5 communication technology communicates through a specific spectrum, and the maximum communication distance is 600 m, which has a problem of communication range. In addition, the PC5 communication technology can only communicate through direct connection and broadcast methods, that is, it can only achieve communication between vehicles and between vehicles and roadside, and cannot achieve communication between vehicles and the cloud. Additional technologies such as the cellular network communication interface Uu are required to communicate with the cloud. Summary of the Invention

The 5G module is used for communication between node end-to-end, thereby building a layer of communication network between nodes.

Through the communication network and the virtual network, a two-layer network architecture is realized, and the broadcast and multicast functions of UDP are realized through the two-layer network architecture. The Cyber RT framework is applied to the two-layer network architecture, enabling the Cyber RT framework to realize that each communication node sends broadcast messages and monitors the joining and leaving of nodes through the two-layer network architecture, thereby realizing the self-organizing network ability of V2X communication.

[0015] Figure 1 It is a structural block diagram of a self-organizing long-distance V2X communication system according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0016] The present invention will be further clarified below in conjunction with the drawings and specific embodiments. It should be understood that these examples are only used to illustrate the present invention and not to limit the scope of the present invention. After reading the present invention, various equivalent forms of modification of the present invention by those skilled in the art all fall within the scope defined by the appended claims of this application.

[0017] A self-organizing long-distance V2X communication module, such asFigure 1 As shown, it includes a 5G module. The 5G module integrates 5G communication technology, provides communication capabilities with large bandwidth and low latency, and supports communication between vehicles, between vehicles and infrastructure, and between vehicles and the cloud. A VPN is built on top of the 5G module. VPN is short for Virtual Private Network, which refers to a virtual private network. In this embodiment, the VPN uses open VPN (an open-source VPN technology). The 5G module is used for communication between node end-to-end, thereby building a layer of communication network between nodes. The VPN implements tunneling technology between nodes through the 5G module, establishes communication tunnels for each node, and thus builds a layer of virtual network between nodes. Through the communication network and the virtual network, a two-layer network architecture is realized, and the broadcast and multicast functions of UDP are realized through the two-layer network architecture. The tunneling technology is used to establish communication tunnels between vehicles, build a two-layer network architecture, and realize the multicast function.

[0018] Apply the Cyber RT framework to the two-layer network architecture. The Cyber RT framework is an open-source and high-performance runtime framework, equipped with the Cyber RT message framework, ensuring that all devices under the entire communication network can communicate in real time and realizing message sharing under the entire topology network. The Cyber RT framework enables each communication node to send broadcast messages through the two-layer network architecture, and at the same time monitors the joining and leaving of nodes, thereby realizing the self-organizing network ability of V2X communication.

[0019] The underlying communication of the entire architecture of this embodiment uses a 5G module, and open VPN is built on top of the 5G module. The 5G module is used for communication between node end-to-end. After installing open VPN, a layer of virtual network is built between nodes. Through the combination of the 5G module and open VPN on the network, a two-layer network architecture is realized. On this network architecture, the broadcast and multicast functions of UDP can be realized. UDP is the abbreviation of User Data Protocol, which refers to the user data protocol. Cyber RT is a real-time communication framework, which belongs to the implementation of the application layer. In the Cyber RT communication framework, each communication node sends broadcast messages, and Cyber RT can monitor the joining and leaving of nodes. After applying the Cyber RT framework to the network structure of 5G plus open VPN, borrowing the broadcast mechanism realized by the two-layer network, all communication nodes applying the Cyber RT mechanism can exchange data with any node.

[0020] As a software framework with powerful real-time performance, Cyber RT injects an efficient real-time communication mechanism into V2X communication. Through Cyber RT, the system can achieve timely and reliable data stream transmission, ensuring that the information exchange between vehicles and infrastructure is not affected by time delay.

[0021] By introducing 5G modules, the system can not only address the issue of short V2X communication distance but also enjoy greater data throughput, lower latency, and higher security. With the support of 5G technology, vehicles and infrastructure can maintain a stable communication connection even at high speeds, providing strong support for the realization of intelligent driving and intelligent road condition perception.

[0022] The introduction of tunneling technology further enhances the reliability and stability of V2X communication. By adopting tunneling technology during the transmission of communication data, the problem of weakened or blocked communication signals in complex environments is successfully solved, strengthening the security of communication between nodes.

[0023] By comprehensively applying the three technologies of Cyber RT mechanism, 5G modules, and tunneling technology, the system has successfully achieved the self-organizing network ability of V2X communication. Vehicles and infrastructure can flexibly establish and maintain communication connections without relying on a specific network architecture. The combined solution of these three technologies has successfully overcome the problem of switching between PC5 and UU communication technologies. Vehicles and infrastructure can smoothly switch between different communication modes without being troubled by communication interruptions or delays caused by technology switching.

[0024] Using 5G module communication, communication can be achieved wherever there is a 5G base station, without distance limitations. By adopting tunneling technology, nodes can achieve multicast communication under a two-layer network architecture. Equipped with the cyber RT framework, it has the function of self-organizing network. By using 5G modules plus the cyber RT framework, V2X communication technology with unlimited distance and self-organizing network ability is realized. By adopting tunneling technology, V2X communication technology with multicast function is realized.

[0025] A self-organizing long-distance V2X communication system, such as Figure 1As shown in the figure, it includes three terminals, namely the cloud platform, the AIOT vehicle-side unit, and the AIOT roadside unit. The cloud platform, the AIOT vehicle-side unit, and the AIOT roadside unit are all equipped with a long-distance V2X communication module that can self-organize a network. During communication, the cloud platform, the AIOT vehicle-side unit, and the AIOT roadside unit respectively act as a communication node, and the nodes communicate with each other through 5G modules to realize the construction of a communication network between the nodes. The VPN establishes a virtual network layer between the nodes through 5G modules, and then realizes a two-layer network architecture through the communication network and the virtual network. The Cyber RT framework performs real-time task scheduling and response through the two-layer network architecture, enabling the Cyber RT framework to realize that each communication node sends broadcast messages and monitors the joining and leaving of nodes through the two-layer network architecture, thereby realizing the self-organizing network ability of V2X communication.

[0026] The cloud platform is provided with a cloud application layer. The long-distance V2X communication module on the cloud platform that can self-organize a network is denoted as communication module one. The 5G module, VPN, and Cyber RT framework on communication module one are respectively denoted as 5G module one, VPN one, and Cyber RT framework one. The VPN one and Cyber RT framework one are installed on the cloud application layer.

[0027] The AIOT vehicle-side unit is provided with a vehicle-end application layer. The long-distance V2X communication module on the AIOT vehicle-side unit that can self-organize a network is denoted as communication module two. The 5G module, VPN, and Cyber RT framework on communication module two are respectively denoted as 5G module two, VPN two, and Cyber RT framework two. The VPN two and Cyber RT framework two are installed on the vehicle-end application layer.

[0028] The AIOT roadside unit is provided with a roadside application layer. The long-distance V2X communication module on the AIOT roadside unit that can self-organize a network is denoted as communication module three. The 5G module, VPN, and Cyber RT framework on communication module three are respectively denoted as 5G module three, VPN three, and Cyber RT framework three. The VPN three and Cyber RT framework three are installed on the roadside application layer.

[0029] Each unit in this embodiment includes four layers of structure, namely the corresponding unit application layer, cyber RT framework, VPN (tunneling technology), and 5G module. The three terminals communicate through 5G technology, and the overall forms a self-organizing network structure.

[0030] After deploying the cloud platform, the AIOT vehicle-side unit, and the AIOT roadside unit into the Cyber RT framework, the three parties respectively create different Cyber RT communication nodes according to their own needs. Each node contains two types of objects, a sender and a receiver, and multiple senders and receivers can be created. When each object is created and initialized, it specifies the channel it wants to listen to or send. This channel is the identifier for communication between each node. After the nodes are created, Cyber RT will add them to a topology network for management. When a new node joins the topology network or a node leaves the topology network, Cyber RT will multicast to all nodes in the same domain and update this topology structure; when a node has data to send, Cyber RT will notify other nodes in the same domain to read the data. In this way, multicast communication is achieved between the three parties, and all three parties can send and receive data, realizing ad-hoc network communication between the three parties.

[0031] A long-distance V2X communication method with ad-hoc network capabilities, as Figure 1 shown. The underlying communication uses 5G modules, and a VPN is built on top of the 5G modules. The 5G modules are used for communication between node end-to-end, thereby building a layer of communication network between nodes. The VPN implements tunneling technology between nodes through the 5G modules to establish communication tunnels for each node, thus building a layer of virtual network between nodes. Through the communication network and the virtual network, a two-layer network architecture is achieved, and the broadcast and multicast functions of UDP are realized through the two-layer network architecture; applying the Cyber RT framework to the two-layer network architecture enables the Cyber RT framework to realize that each communication node sends broadcast messages while monitoring the joining and leaving of nodes through the two-layer network architecture, thereby realizing the ad-hoc network capability of V2X communication.

[0032] In this embodiment, 5G modules are integrated into the vehicle communication system and the compatibility with the vehicle system is ensured. The 5G communication protocol parameters are configured to ensure that the vehicle can perform efficient V2X communication. The cyber RT framework is deployed on each communication node to provide real-time task scheduling and response. By implementing tunneling technology such as building a VPN (Virtual Private Network), communication tunnels for each device are established to realize the multicast function. Utilizing the tunneling technology and the ad-hoc network function of cyber RT, the vehicle can automatically establish and manage the communication network according to the surrounding environment.

[0033] By organically combining the Cyber RT mechanism, 5G modules, and tunneling technology, the present invention successfully solves a series of challenges faced by current V2X communication, including short communication distance, lack of support for ad-hoc network communication, and the need not to switch between PC5 and UU communication technologies, etc.

[0034] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
