Description

Technical Field

[0001] This invention belongs to the field of communication network technology, specifically relating to a dual-mode intelligent vehicle networking communication control method and system. Background Technology

[0002] In the field of vehicle cluster collaborative operations, which covers many scenarios such as unmanned mining truck transportation, intelligent logistics platooning, military vehicle mobility, and port container transshipment, building a vehicle-mounted communication network with high reliability, low latency, and high bandwidth is a key foundation for achieving intelligent command, control, and status synchronization.

[0003] For example, patent document CN120669579A discloses an on-board control system based on a dual-controller architecture, including a control module, an expansion module, a power supply module, a communication self-test module, and a fault-tolerant decision execution module. The control module includes a main control unit and a slave control unit. The expansion module provides several expandable interfaces. The power supply module can perform power supply protection. The communication self-test module can determine whether communication has timed out based on communication data and perform multi-dimensional fault characteristic joint diagnosis. The fault-tolerant decision execution module can adjust the transmission of the control module. This invention improves the system redundancy of the on-board control system and improves the working stability under harsh conditions through the dual-controller design.

[0004] For example, patent document CN118158639A discloses a time-division duplex-based vehicle-mounted wireless ad hoc network communication system, including a software-defined radio transceiver, an antenna module, a power supply module, a signal amplification module, a data interface, and a voice processing module. The power supply module, signal amplification module, data interface, and voice processing module are respectively connected to the software-defined radio transceiver. The antenna module is connected to the signal amplification module. The software-defined radio transceiver is used for workshop wireless ad hoc network communication. The antenna module is used to receive and transmit fixed-frequency signals. The signal amplification module amplifies the received and transmitted fixed-frequency signals from the antenna module. The data interface is used to connect to external data transmission equipment. The voice processing module is used to process the input voice signal. This invention enables real-time and efficient collaborative operation between vehicles, providing data support for the system.

[0005] However, the main technical solutions for achieving vehicle-to-vehicle communication and their existing problems are as follows: 1. Pure Wireless Solution: This solution utilizes Wi-Fi, Zigbee, or radio components to achieve a self-organizing network (MANET). However, this solution has significant drawbacks. Its signal is highly susceptible to terrain, obstructions, and electromagnetic interference, exhibiting poor stability, limited bandwidth, and high latency jitter. In complex operating environments, there is also a high risk of communication interruption, making it difficult to guarantee stable and reliable communication.

[0006] 2. Wired Solution: This solution uses physical cables to connect vehicles for communication. While it offers advantages such as stability and high speed, it significantly limits vehicle maneuverability and flexibility. Cable installation is not only cumbersome, but the cables are also prone to breakage or wear during vehicle operation. Such incidents can lead to single points of failure, causing communication interruptions and severely impacting vehicle operations.

[0007] 3. Dual-line communication network: In common dual-mode networking schemes, wired and wireless links operate independently, lacking intelligent link management and redundancy backup mechanisms. When a single link fails, seamless switching cannot be achieved, making it difficult to meet the stringent requirements for high reliability and high availability of communication during vehicle movement, thus posing significant limitations in practical applications.

[0008] 4. Simple Master-Slave Network: Existing networking methods suffer from rigid network topologies, typically employing a star topology with one master and multiple slaves. In increasingly complex industrial and production environments, this simple topology can no longer meet the higher demands of communication networking and struggles to satisfy the requirements for communication flexibility and scalability in collaborative vehicle operations.

[0009] Furthermore, existing technologies suffer from systemic shortcomings that urgently need to be addressed. It is difficult to simultaneously achieve reliability, stability, and flexibility. While wireless communication offers flexibility, its stability is relatively poor, while wired communication offers strong stability but restricts mobility. Currently, there is a lack of comprehensive solutions that effectively combine the advantages of both while mitigating their disadvantages. They are weak in anti-interference and environmental adaptability, especially in complex industrial environments or environments with strong electromagnetic interference, where the performance of purely wireless solutions deteriorates sharply, failing to guarantee reliable transmission of critical business data. Network robustness is poor; the lack of effective multipath transmission and fault self-healing mechanisms leads to insufficient system robustness. The topology is rigid, resulting in a thin network structure that cannot be dynamically adjusted during application, making it difficult to cover complex application scenarios. The level of intelligence is low; link selection and maintenance, as well as the formation of the communication network topology, rely on manual intervention or higher-level applications, resulting in slow response times and preventing truly continuous communication.

[0010] Therefore, there is an urgent need in this field for an innovative technical solution that can provide a communication system for vehicle platooning in complex scenarios that combines high reliability and high mobility, and has intelligent redundancy backup and rapid automatic switching capabilities. Summary of the Invention

[0011] To address the shortcomings of existing technologies, the present invention aims to provide a dual-mode intelligent vehicle networking communication control system, comprising: a main control module, a wired communication module, a radio module, and a voice processing module; the main control module performs routing decisions, data exchange, and system control tasks; the wired communication module handles external wired network connections; the radio module transmits wireless link data, sending data from the main control module through a wireless channel and receiving wireless data from other communication controllers, uploading it to the main control module; the voice processing module is responsible for acquiring, digitizing, and compressing analog voice signals; the main control module, wired communication module, radio module, and voice processing module are tightly coupled through an internal network and bus, forming a complete data processing and forwarding system.

[0012] Preferably, the data processing and forwarding system includes: an uplink data stream for receiving data and a downlink data stream for sending data.

[0013] The aforementioned uplink data stream specifically refers to external data entering the controller through a wired communication module or radio module, being aggregated to the main control module via a switching chip, and then forwarded by the main control module to the voice processing module or sent to the vehicle's host computer through the host computer interface, based on the destination IP address of the data packet and the built-in routing table.

[0014] The downlink data stream specifically refers to the delivery of network data from the vehicle's host computer or voice IP packets generated by the voice processing module to the main control module. The main control module's link management logic can prioritize wired links and send data packets to the wired communication module via the switching chip. If the wired link is disconnected or does not exist, the data packets are immediately routed to the radio module for wireless transmission.

[0015] The main control module, as the core module of the communication controller, completes the tasks of routing decision-making, data exchange, and system control. The main control module runs an embedded operating system and executes the core link status monitoring algorithm and intelligent routing switching logic. It uses an Ethernet switching chip to connect to the internal MAC via SMI and MII interfaces. The main control module configures and manages the chip, building an internal data exchange backbone. Its multiple ports are connected to the wired communication module, voice processing module, radio module, and host computer interface, respectively, to realize high-speed, Layer 2 network data exchange between internal functional modules and with the outside world.

[0016] The wired communication module uses a chip of the same model as the main control module as its CPU, ensuring uniformity in hardware and software design and availability of spare parts. The wired communication module handles external wired network connections and has five interfaces, each corresponding to two links, for a total of ten links. This means each communication controller can connect to ten other communication controllers via the wired communication module. The maximum transmission rate of the wired communication module can reach 8MB / s. Furthermore, the wired communication module connects to the main control module's exchange chip via an internal network cable at a designated port. Its main function is to receive and send data from external wired links and then route the data to the main control module.

[0017] The core component of the radio module is an ultra-shortwave tactical communication radio module, which has frequency hopping, anti-interference and long-distance transmission capabilities. The ultra-shortwave radio is connected to another port of the main control module's switching chip through an Ethernet interface. The radio module is responsible for transmitting wireless link data, sending out the data sent by the main control module through the wireless channel, and receiving wireless data from other communication controllers and uploading it to the main control module.

[0018] Preferably, the core processor of the voice processing module has a DSP instruction set and a high-performance floating-point arithmetic unit, which can perform audio encoding and decoding, filtering, echo cancellation, and digital signal processing. The voice processing module is connected to the microphone and speaker, and is responsible for acquiring, digitizing, and compressing analog voice signals, as well as decoding, converting digital to analog, and playing the received digital voice data. The encoded digital voice data packets are transmitted to the main control module through the Ethernet interface. The main control module performs routing decisions on the voice data packets and ordinary network data packets together, and transmits them through wired or wireless links to realize IP-based voice communication. At the same time, the voice processing module uses an independent chip to process voice.

[0019] This invention provides a dual-mode intelligent vehicle networking communication control method. The dual-mode intelligent vehicle networking communication control system includes a main control module that performs routing decisions, data exchange, and system control; a wired communication module that handles external wired network connections; a radio module that transmits wireless link data; and a voice processing module that collects, digitizes, and compresses analog voice signals.

[0020] This invention proposes a communication control device, which includes the aforementioned dual-mode intelligent vehicle networking communication control system.

[0021] Compared with the prior art, the present invention has the following beneficial effects: 1. High performance: Based on the system's functional requirements, a hardware system was designed with STMicroelectronics STM32H743ZI high-performance ARM Cortex-M7 microprocessor and Broadcom BCM53242 Ethernet switching chip as the main components, which can meet the needs of high-speed communication and has a small hardware resource consumption.

[0022] 2. High reliability: It combines the advantages of stable and high speed in wired mode and flexible and mobile wireless mode. The two transmission modes serve as backups for each other, realizing effective multi-path transmission and fault self-healing mechanism, and can complete uninterrupted data transmission in complex industrial or strong electromagnetic environments.

[0023] 3. Intelligent: Each communication controller can be independently configured with an identity type and can autonomously switch between wired and wireless modes according to the connection status. It can also adaptively adjust the network structure according to changes in the number of vehicles on the network and their identity types. The process does not rely on upper-level applications or manual instructions, and the response speed is fast, meeting the requirements of high reliability and high availability of communication for vehicles during movement.

[0024] 4. Wide applicability: The identity type of the communication controller can be modified at any time during use to realize intelligent custom networking, form a multi-level network topology, and adapt to different application scenarios. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0027] This invention proposes a dual-mode intelligent vehicle networking communication control system, comprising: a main control module, a wired communication module, a radio module, and a voice processing module. The main control module performs routing decisions, data exchange, and system control. The wired communication module is specifically responsible for handling external wired network connections. The radio module is responsible for transmitting wireless link data, sending data from the main control module through a wireless channel, and receiving wireless data from other communication controllers and uploading it to the main control module. The voice processing module is responsible for acquiring, digitizing, and compressing analog voice signals. The main control module, wired communication module, radio module, and voice processing module are tightly coupled through an internal network and bus, forming a complete data processing and forwarding system. As attached Figure 4 and 5 As shown, the data processing and forwarding system includes: an uplink data stream responsible for receiving data and a downlink data stream responsible for sending data. The aforementioned uplink data stream specifically refers to external data entering the controller via a wired communication module or radio module, being aggregated to the main control module STM32H743 via the BCM53242 switching chip, and then forwarded by the STM32H743 to the voice processing module or to the vehicle's host computer via the host computer interface, based on the destination IP address of the data packet and the built-in routing table.

[0028] The downlink data stream specifically refers to the delivery of network data from the host computer of this vehicle or voice IP packets generated by the voice processing module to the main control module. The STM32H743 link management logic prioritizes wired links and sends data packets to the wired communication module through the BCM53242 switching chip; if the wired link is disconnected or does not exist, the data packets are immediately routed to the radio module for wireless transmission.

[0029] The main control module, as the core module of the communication controller, completes the tasks of routing decision-making, data exchange, and system control. The main control module uses an STM32H743 as the main control CPU, runs the embedded operating system RT-thread, and executes the core link status monitoring algorithm and intelligent routing switching logic. It uses a Broadcom BCM53242 Ethernet switching chip to connect to the internal MAC of the STM32H743 through the SMI and MII interfaces. The STM32H743 configures and manages the chip, building an internal data exchange backbone. Its multiple ports are connected to the wired communication module, voice processing module, radio module, and host computer interface, respectively, to realize high-speed, Layer 2 network data exchange between internal functional modules and with the outside world.

[0030] The wired communication module uses the same STM32H743 chip as the main control module as its CPU, ensuring unified hardware and software design and spare parts availability. This module is dedicated to handling external wired network connections. It has five interfaces, each corresponding to two links, for a total of ten links. This means each communication controller can connect to ten other communication controllers via the wired communication module. The maximum transmission rate of the wired communication module can reach 8MB / s. Furthermore, the wired communication module connects to the main control module's exchange chip via an internal network cable at a designated port. Its main function is to receive and send data from external wired links and then route the data to the main control module.

[0031] The core component of the radio module is an ultra-shortwave tactical communication radio module, which operates in the frequency band between 30 and 87.975 MHz. It has frequency hopping, anti-interference, and long-distance transmission capabilities. The ultra-shortwave radio is connected to another port of the main control module's switching chip via an Ethernet interface. The radio module is responsible for transmitting wireless link data, sending out the data sent by the main control module through the wireless channel, and receiving wireless data from other communication controllers and uploading it to the main control module.

[0032] As attached Figure 6As shown, the core processor of the voice processing module uses STMicroelectronics' STM32F429IG microprocessor. This chip has a DSP instruction set and a high-performance floating-point unit (FPU) for digital signal processing algorithms such as audio encoding / decoding, filtering, and echo cancellation. The voice processing module has audio encoding / decoding and voice routing functions. It connects to the microphone and speaker, and is responsible for acquiring, digitizing, and compressing analog voice signals, as well as decoding, converting digital-to-analog conversion, and playing back the received digital voice data. The encoded digital voice data packets are transmitted to the STM32H743 chip in the main control module via an Ethernet interface. The main control module performs routing decisions on the voice data packets along with ordinary network data packets, and transmits them through wired or wireless links to achieve IP-based voice communication. Simultaneously, the voice processing module uses an independent chip to process voice, avoiding resource contention with the main control module, ensuring real-time voice processing and low latency, resulting in higher call quality.

[0033] Preferably, the present invention proposes a dual-mode intelligent vehicle networking communication control method, comprising: configuring a convoy of 7 vehicles as follows: Figure 1 The formation shown forms a three-tiered network topology centered on Command Vehicle 1. This structure contains three independent communication networks: Command Vehicle 1-Work Vehicle A-Command Vehicle 2, Command Vehicle 1-Work Vehicle B1-Work Vehicle B2, and Command Vehicle 2-Work Vehicle C1-Work Vehicle C2. Each network independently transmits information and maintains its links, enabling automatic switching between wired and wireless modes and adaptive structural adjustments based on changes in the number and status of vehicles within the network.

[0034] Furthermore, this invention proposes a dual-mode intelligent vehicle networking communication control method, comprising the following steps: Step S1: Set the identity type of the 7 vehicles on the interaction panel of each communication controller, such as... Figure 1 As shown, there are four types, distinguished by numbers within the same type: Command Vehicle 1, Command Vehicle 2, Work Vehicle A, Work Vehicle B1, Work Vehicle B2, Work Vehicle C1, and Work Vehicle C2. Subsequent communication network setup and data transmission / reception will use the vehicle's identification type as its identifier address. This is to construct... Figure 1 The network structure shown indicates that the command vehicle is equipped with two radio modules to access two independent communication networks, and the wired module lines are connected according to... Figure 1 The connection is shown. After correctly configuring the communication controller, wired module, and wireless module of each vehicle, the communication controller will automatically perform addressing and network establishment operations according to the vehicle's identity type.

[0035] Step S2: The command vehicle periodically sends routing information. When the command vehicle's communication controller is working normally, it will simultaneously send routing information to its established physical channels via wired communication module and radio module at regular intervals. This routing information includes the type of the command vehicle, the command vehicle number, the identity of the destination vehicle of this message (the destination vehicle of the routing information is all vehicles), and the identity of the source vehicle of the routing information received by this vehicle, and other relevant information, and connects and synchronizes with the communication controllers on other vehicles.

[0036] Step S3: The work vehicle receives routing information. After receiving routing information, the communication controller on the work vehicle first parses the source vehicle identity from the data: if it is identified as a work vehicle, the routing information is not processed; if it is a command vehicle, it checks whether it has received routing information from a command vehicle with a higher number; if so, the routing information is not processed; if the routing information comes from the highest-numbered command vehicle it has received so far, it records the command vehicle's identity and number, and then periodically sends routing information to the command vehicle's identity address. The information includes the work vehicle's identity type, work vehicle identity number, and the destination vehicle's identity address. Then, it reads the list of vehicles that the command vehicle has received information from. If the work vehicle's identity is in the list, it proves that the command vehicle has received the routing message from this vehicle, and the two vehicles have successfully handshaked. By identifying the physical network port that received the message, the connection method of the link between the two work vehicles can be obtained, and the command vehicle's identity information and connection method are stored in the work vehicle's routing table.

[0037] Step S4: The command vehicle receives routing information. After receiving the routing information, the communication controller on the command vehicle first parses the source vehicle identity from the data: if it is identified as the command vehicle and the vehicle identity number is greater than that of the current vehicle, it is processed according to the logic of the working vehicle receiving the routing information from the command vehicle; otherwise, it checks whether the vehicle information has been received before from the list of vehicles that have received information. If it has been received, it stores the connection method obtained from the physical network port of the link and the vehicle identity type together in the routing table of the current vehicle; if the vehicle routing information has not been received, it adds the vehicle identity type and number to the list of vehicles that have received information, updates the routing information content sent by the command vehicle in step S2, and starts a new round of network construction.

[0038] Step S5: Wired / Wireless Switching Once the link is successfully established, the communication controllers of both the command vehicle and the work vehicle will continuously and periodically send routing information to ensure the link's stability. When a wired link exists between the two workshops, data is transmitted via the wired link. If the wired link is broken, i.e., after this vehicle sends routing information three times consecutively without receiving a response from the other party, the communication controller will determine that the path no longer exists and will delete the wired link record between the two workshops from the routing table. If the two workshops still have data communication needs at this time, the communication controller will search for an existing connection method based on its own routing table, and will automatically switch to wireless transmission via the radio module, completing the route conversion.

[0039] Step S6: Identity switch, Command vehicle 2 offline. Once the link is successfully established, the communication controllers of the command vehicle and the work vehicle will be stably maintained as follows: Figure 1 The illustrated 7-vehicle, three-level, three-network linked structure is shown. When the command vehicle 2 is physically disconnected from the network structure, the upstream command vehicle 1 and the downstream work vehicles C1 and C2 in the original network link of command vehicle 2 will delete their routing records from their respective routing tables after failing to receive routing information from command vehicle 2 for three consecutive times. At this time, work vehicles C1 and C2 will receive and process the routing information from command vehicle 1, and with the functional support of the wired and wireless modules, will integrate into the lower-level network of command vehicle 1, forming a network as shown below. Figure 2 The link architecture shown enables automatic reconfiguration and communication maintenance of the network architecture in the special case of a vehicle suddenly losing network access.

[0040] Step S7: Command Vehicle 2 goes online Waiting Figure 2 After the network structure stabilizes, the wired / wireless modules of the command vehicle are reconnected to the original upstream and downstream links. Upon receiving routing information from command vehicle 2, command vehicle 1, work vehicle C1, and work vehicle C2 will again process the information and update the routing table according to the logic in steps S3 and S4. Work vehicle C1 and work vehicle C2 will then re-establish network connectivity with command vehicle 2, disconnect the master-slave link with command vehicle 1, and restore the network as described above. Figure 1 The three-level network structure is shown.

[0041] Step S8: Processing of transmitted and received data Connect the user terminal to the switching chip of the communication controller via the reserved network port, such as Figure 3 As shown, data transmission between users within the network can be carried out while adhering to the data transmission protocol. Users can select the destination vehicle for data transmission (unicast to vehicles within the network or broadcast to all vehicles in the network). After routing and processing by the communication controller, only vehicles within the destination address range can receive the data, which greatly reduces data redundancy in the communication network.

[0042] Step S9: Voice Processing Users make calls via a handset. When the sender speaks, the voice data is converted into an electrical signal by the microphone, then amplified by an audio amplifier, and finally converted into a digital signal by an analog-to-digital converter. The communication controller then sends the signal according to the routing information, enabling communication between vehicles.

[0043] As can be seen from the above results, by equipping the vehicle with a communication controller to configure the vehicle's identity type and identity number, the vehicle can automatically establish a communication network based on the set number of identities via the wired and wireless modules of the communication control system.

[0044] This invention also proposes a dual-mode intelligent vehicle networking communication control method. The dual-mode intelligent vehicle networking communication control system includes a main control module that performs routing decisions, data exchange, and system control; a wired communication module that handles external wired network connections; a radio module that transmits wireless link data; and a voice processing module that collects, digitizes, and compresses analog voice signals.
