[0043] Example 1

[0044] like Figure 1 As shown, the present disclosure provides a board, comprising:

[0045] The main board 1 is provided with a gold finger connector 2, and the gold finger connector 2 is used to connect with the roadside computing unit;

[0046] A vehicle wireless communication module 3 is arranged on the main board 1;

[0047] The bus conversion module 4 is disposed on the main board 1 , and the bus conversion module 4 is communicatively connected with the vehicle wireless communication module 3 and the gold finger connector 2 respectively.

[0048] Specifically, as the core of the entire board, the mainboard 1 provides an infrastructure for carrying and connecting other modules. These modules are installed on the mainboard 1 and communicate and work together through preset circuit paths and interfaces.

[0049] The gold finger connector 2 is a physical interface between the main board 1 and the roadside computing unit. It is used to provide a stable and reliable mechanical connection, so that electronic signals can be transmitted from the board to the roadside computing unit, realizing information transmission and system interaction. In addition, the gold finger connector 2 has a high density of contacts or pins, which can achieve a large amount of signal transmission in a very small space compared to the traditional RSU device and the roadside computing unit connected via a network cable. The high-density contact design of the gold finger connector 2 can transmit more data at the same time, so it can effectively reduce the latency of the data link. In addition, since this connection method does not require the laying and management of a large number of network cables, it simplifies the hardware equipment deployment process of the Internet of Vehicles and reduces installation and maintenance costs.

[0050] The vehicle wireless communication module 3 is used to receive data generated by the vehicle's internal systems and sensors, including but not limited to vehicle status information (such as speed, location, fault code, etc.), driver operation data (such as braking, steering, acceleration, etc.), environmental perception data (such as information collected by radar, camera, lidar sensors, etc.) and data generated by other vehicle-mounted devices.

[0051] The vehicle wireless communication module 3 is configured with a USB Type-A (Universal Serial Bus Type-A) or Type-C (Universal Serial Bus Type-C) for electrically connecting to the downstream interface of the bus conversion module 4 for data transmission and control signal exchange.

[0052] Since the vehicle wireless communication module 3 is in communication connection with the bus conversion module 4, the vehicle wireless communication module 3 can transmit the collected data to the bus conversion module 4 for processing and further transmission. The bus conversion module 4 is responsible for converting between different communication interfaces and protocols to ensure that the data can be correctly transmitted and understood.

[0053] The vehicle wireless communication module 3 can select a V2V communication module (Vehicle-to-Vehicle Communication Module), a dedicated short-range communication module, etc., so that the vehicle can exchange information with other vehicles, traffic infrastructure and cloud services in real time, providing the necessary communication capabilities for realizing advanced driver assistance systems, automatic driving, intelligent traffic management and other applications.

[0054] The bus conversion module 4 plays a key role in the conversion of the communication interface. It can adapt to the differences in data transmission protocols and electrical characteristics between different modules, and ensure that data can be exchanged accurately and efficiently between various modules.

[0055] The bus conversion module 4 is configured with a downstream interface and an upstream interface, the downstream interface can be a USB Type-A or Type-C downstream interface, there can be multiple downstream interfaces, one of which is used to electrically connect to the vehicle wireless communication module 3. The upstream interface is a PCIe interface (Peripheral Component Interconnect Express), which is connected to the roadside computing server to upload the received data to the roadside computing server and forward the business data that needs to be sent.

[0056] The bus conversion module 4 receives data from the vehicle wireless communication module 3 and sends the data to the roadside computing unit through the gold finger connector 2. In this process, it plays the role of data bridging and integrates and converts data between different modules. The bus conversion module 4 converts the data received by the vehicle wireless communication module 3 from one protocol format to another protocol format so as to effectively exchange data with the roadside computing unit connected to the gold finger.

[0057] The bus conversion module 4 can be connected to the gold finger connector 2 through a data transmission cable 8 to ensure the stability and reliability of data transmission, so that the board can flexibly adapt to different communication environments and application requirements, thereby improving overall performance and compatibility.

[0058] The board design of the present application realizes the integrated layout of the vehicle wireless communication module 3 and the bus conversion module 4. The vehicle wireless communication module 3 and the bus conversion module 4 are integrated on the main board 1 to form a tightly coordinated system; the bus conversion module 4 can obtain various data received by the vehicle wireless communication module 3, and efficiently transmit the obtained data to the roadside computing unit through the gold finger connector 2, which greatly reduces the intermediate links of data transmission, thereby effectively reducing the delay of the data link. In addition, compared with the traditional decentralized equipment configuration, the board design of the present application reduces the number and complexity of hardware equipment, making equipment installation, maintenance and upgrading more convenient, thereby significantly reducing the overall deployment and operation costs.

[0059] Preferably, the bus conversion module 4 is connected to the vehicle wireless communication module 3 via wired communication or wireless communication.

[0060] Specifically, wired communication has higher data transmission stability, and can provide higher data transmission speed and higher security performance; wireless communication does not require physical wiring, reducing the complexity and workload of wiring. The specific communication method between the bus conversion module 4 and the vehicle wireless communication module 3 can be based on demand and environmental conditions. In this application, wired communication is preferred.

[0061] Preferably, the bus conversion module 4 is provided with a universal serial bus interface.

[0062] Specifically, the universal serial bus interface is a widely used interface standard. By setting the universal serial bus interface, it is possible to achieve communication and data exchange with various different devices and modules.

[0063] like Figure 1 As shown, as a preference, it also includes a first universal serial bus cable 5 arranged on the mainboard 1;

[0064] One end of the first universal serial bus cable 5 is connected to the vehicle wireless communication module 3 for communication, and the other end of the first universal serial bus cable 5 is connected to the vehicle wireless communication module 3 for communication via a universal serial bus interface.

[0065] Specifically, the universal serial bus cable supports high-speed data transmission and can meet the real-time transmission requirements of large amounts of data in vehicle communications. The first universal serial bus cable 5 is used to realize the communication connection between the vehicle wireless communication module 3 and the bus conversion module 4, ensuring that data can be stably and reliably transmitted between the two modules.

[0066] Due to the widespread application and standardized production of USB interfaces and USB cables, the related hardware and software resources are abundant and relatively low in cost, which helps to reduce the cost of the entire system.

[0067] Preferably, there are multiple universal serial bus interfaces.

[0068] Specifically, multiple universal serial bus interfaces can simultaneously transmit data, realize parallel processing and high-speed communication. In applications that process large amounts of data or high bandwidth requirements, multiple universal serial bus interfaces can also disperse data traffic, reduce the data transmission pressure of a single interface, and thus reduce bottlenecks and delays in data transmission. The number of universal serial bus interfaces can be 2, 3, 4, 5, 6 or even more.

[0069] The vehicle wireless communication module 3 can be set on the main board 1 by surface mounting technology, through-hole mounting technology, etc.; the bus conversion module 4 can be set on the main board 1 by surface mounting technology, through-hole mounting technology, etc.; or, as a preference, the vehicle wireless communication module 3 and the bus conversion module 4 are both set on the main board 1 by printing.

[0070] Specifically, by directly setting the vehicle wireless communication module 3 and the bus conversion module 4 on the mainboard 1 through printing technology, hardware integration and compact design can be achieved. This design reduces additional connectors, cables and packaging materials, making the board smaller and more suitable for installation in a limited space. In addition, the printed circuit board manufacturing process is mature and reliable. By integrating the vehicle wireless communication module 3 and the bus conversion module 4 on the mainboard 1 through printing, the risk of failure caused by loose physical connection, poor contact or cable damage can be reduced, the overall reliability of the system can be improved, and the production process can be simplified, the assembly steps and manual intervention can be reduced, and production efficiency and quality control can be improved.

[0074] Specifically, the addition of a wireless network communication module 6 enables the board to support multiple wireless communication technologies at the same time, thereby enhancing the vehicle's ability to interconnect with other devices or networks. Moreover, the wireless network communication module 6 can provide a wider communication coverage, allowing the vehicle to exchange data and transmit information even when it is far away from the roadside computing unit or other infrastructure, which is crucial for realizing remote monitoring, fault diagnosis, software updates and various on-board services (such as navigation, entertainment, safety warnings, etc.) of the vehicle.

[0075] The wireless network communication module is configured with a USB Type-A or Type-C interface for electrically connecting to the downstream interface of the bus conversion module 4 for data transmission and control signal exchange.

[0076] Preferably, the wireless network communication module 6 is connected to the bus conversion module 4 via wired communication or wireless communication.

[0077] Preferably, it also includes a second universal serial bus cable 9 arranged on the mainboard 1;

[0078] One end of the second universal serial bus cable 9 is connected to the wireless network communication module 6 for communication, and the other end of the second universal serial bus cable 9 is connected to the bus conversion module 4 for communication via a universal serial bus interface.

[0079] like Figure 2As shown, preferably, the wireless network communication module 6 and the vehicle wireless communication module 3 are respectively arranged on both sides of the bus conversion module 4 along the first direction A, and the gold finger connector 2 is arranged on one side of the mainboard 1 along the second direction B; the first direction A is the length direction of the mainboard 1, and the second direction B is the width direction of the mainboard 1.

[0080] Specifically, the wireless network communication module 6 and the vehicle wireless communication module 3 are respectively arranged on both sides of the bus conversion module 4, which can make full use of the length direction space of the mainboard 1, avoid line crossing and confusion, simplify the wiring design, and help improve production efficiency and reduce failure rate, reduce mutual interference between modules, and also facilitate heat dissipation and maintenance, and can also reduce interference to a certain extent and improve communication quality.

[0083] The mobile network communication module 7 is communicatively connected with the bus conversion module 4 .

[0084] Specifically, the mobile network communication module 7 can utilize a wide range of mobile communication networks for data transmission, so that the vehicle can still maintain communication connection with the outside world when it is far away from fixed communication facilities. In addition, the mobile network communication module 7 supports high-speed data transmission rate and large data capacity, which is very beneficial for transmitting high-capacity information such as high-definition video, large amounts of sensor data, software updates, etc. And through the mobile network communication module 7, real-time remote monitoring and fault diagnosis of the vehicle can be achieved, problems can be discovered and solved in a timely manner, and driving safety and maintenance efficiency can be improved.

[0085] The mobile network communication module 7 is configured with a USB Type-A or Type-C interface, which is used to be electrically connected to the downstream interface of the bus conversion module 4 for data transmission and control signal exchange.

[0092] Specifically, the wireless network communication module 6 and the mobile network communication module 7 provide multiple communication paths, which increase the reliability and stability of the system.
