[0018] Gateway transparent transmission technology is primarily used to improve data reception efficiency and data stability, and is widely used in fields such as industrial automation and intelligent manufacturing. Its core goal is to enable lossless communication between devices in different network environments. This technology will be further applied in more scenarios with high real-time requirements. The UDP (User Datagram Protocol) in the other text refers to the UDP communication protocol. UDP is a connectionless transport layer network protocol, alongside TCP (Transmission Control Protocol). It is often used in scenarios with high real-time requirements and tolerance for small amounts of data loss. It features connectionless, lightweight, and datagram-oriented features. Gateway transparent transmission is a network communication technology whose core is to achieve "transparent transmission" of data through a gateway. That is, data is not parsed or modified when passing through the gateway, but is only forwarded.

[0019] DBC is a standard file format used in automotive electronics to describe the Controller Area Network (CAN) communication protocol.

[0020] Gateway: A device that connects different networks (such as a home router or industrial gateway), usually used for protocol conversion, routing, and forwarding.

[0021] Pass-Through: When data passes from the sender to the receiver via the gateway, the gateway does not process the data content (such as parsing or modifying it). It is only responsible for establishing the transmission channel and forwarding data, similar to the "pipeline" function. This is also the main function of conventional gateway pass-through, which maintains the forwarding capability and data integrity of the network layer. Complex protocol conversion requirements need to be combined with protocol parsing functions.

[0022] This application provides a DBC gateway transparent transmission method based on UDP communication that can be applied in Figure 1 In the transparent transmission system shown in Figure 1 As shown, the transparent transmission system may include: a data processing center, a host computer that monitors the target electronic unit, a DBC gateway, and a DBC module connected to the target electronic unit. The data processing center establishes a UDP communication connection with the host computer. The data processing center is configured to: receive in real time the current DBC data output by the DBC module and transparently transmitted via the DBC gateway; the current DBC data may include different DBC sub-data corresponding to the target electronic unit; process the current DBC data based on a pre-stored DBC data set and corresponding data processing logic to obtain monitoring data for the target electronic unit; the DBC data set and corresponding data processing logic are pre-transmitted by the host computer via a UDP communication connection; and transmit the stored monitoring data to the host computer via the UDP communication connection. The target electronic unit may be a battery pack (also known as a "power battery") containing multiple battery cells, or an electronic device containing multiple DBC data capable of transmitting and receiving DBC data.

[0023] Correspondingly, the data processing center can also send business data to the DBC module through the DBC gateway based on the instructions of the host computer.

[0024] In the DBC gateway transparent transmission method based on UDP communication provided in this application, when the host computer sends configuration data (including DBC data volume set and corresponding data processing logic) via UDP communication, the data processing center receives the configuration data, parses the data area required to be opened in the configuration data, initializes the data area (initializes the cache queue and calculation logic thread), and caches the data processing logic in the configuration data in the data processing center, allowing the data processing center to dynamically obtain the calculation logic. Through the dynamic logic calculation and data caching, the problem of long-term dependence on the stability of the underlying network in transparent transmission can be effectively solved. Even if the UDP communication is unstable, it can ensure that the data sent by the DBC module can still be sent to the data processing center normally and processed, reducing the dependence on the network. Because it can dynamically expand the calculation logic, it solves the traditional defect of transparent transmission without data processing. At the same time, in order to handle the situation where the DBC data is too large, a cache queue can be added, allowing the data processing center to automatically divert and reduce pressure when overloaded, reducing the pressure on the gateway and improving the resource utilization of the system.

[0025] The preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application can be combined with each other if there is no conflict.

[0026] Figure 2 The present invention provides a flow chart of a DBC gateway transparent transmission method based on UDP communication. Figure 2 As shown, the method may include: Step S210: receiving in real time the current DBC data output by the DBC module and transparently transmitted through the DBC gateway.

[0027] The current DBC data may include sub-DBC data of different data types corresponding to the target electronic unit. The sub-DBC data of different data types include sub-DBC data of different data types related to each component included in the target electronic unit; any sub-DBC data may include the DBC data name, CANID, start bit, and end bit related to the corresponding component.

[0028] For example, the target electronic unit includes 3 components, and the current DBC data can be expressed as: [sub-DBC data of data type 1 of the 1st component, sub-DBC data of data type 2 of the 1st component, sub-DBC data of data type 1 of the 2nd component, sub-DBC data of data type 2 of the 2nd component, sub-DBC data of data type 1 of the 3rd component, sub-DBC data of data type 2 of the 3rd component].

[0029] Since the sub-DBC data includes the DBC data name, CANID, start bit and end bit involved in each component, the current DBC data may include the DBC data name, CANID set, start bit and end bit of each sub-DBC data.

[0030] In one example, when the target electronic unit is a battery pack and the battery pack includes three battery cells, the different sub-DBC data included in the current DBC data are sub-DBC data of different data types collected for the battery pack (such as sub-DBC data of temperature data type and sub-DBC data of voltage data type), wherein the sub-DBC data of different data types include sub-DBC data of different data types for each of the three battery cells.

[0031] In some embodiments, after receiving the current DBC data output by the DBC module and transparently transmitted through the DBC gateway in real time, if the current DBC data is greater than a data threshold, the current DBC data may be cached.

[0032] Step S220: Based on the pre-stored DBC data volume set and corresponding data processing logic, the current DBC data is processed to obtain monitoring data of the target electronic unit.

[0033] The pre-stored DBC data set and the corresponding data processing logic are pre-transmitted by the host computer via a UDP communication connection. The data processing logic can be a calculation logic for extreme values ​​(such as maximum and minimum values) and average values.

[0034] In a specific implementation, based on the pre-stored DBC data volume set and the start bit and end bit of each sub-DBC data in the current DBC data, the sub-DBC data of different data types corresponding to each component in the current DBC data are allocated data volume to obtain multiple allocated data volumes; The data processing logic is used to process the multiple data amounts after allocation according to the data type to obtain the monitoring data of the target electronic unit.

[0035] Step S230: Send the monitoring data to the host computer via the UDP communication connection.

[0036] In specific implementation, the UDP communication connection can be monitored in real time to obtain monitoring results; If the monitoring result is that the UDP communication connection is online, the stored monitoring data will be sent to the host computer in real time through the UDP communication connection.

[0037] If the monitoring result is that the UDP communication connection is offline, the monitoring data of the target electronic unit is stored in the configured cache queue, and the execution step is returned to: real-time monitoring of the UDP communication connection is performed to obtain the monitoring result until the monitoring result is that the UDP communication connection is online, so as to send the monitoring data to the host computer.

[0038] In some embodiments, after obtaining the monitoring data of the target electronic unit in step S220, the monitoring data of the target electronic unit can also be stored in a configured cache queue; and a data acquisition request sent by the host computer through the UDP communication connection is received, and based on the data acquisition request, the monitoring data in the cache queue is read.

[0039] Furthermore, when the monitoring result shows that the UDP communication connection is online and after receiving a data acquisition request sent by the host computer through the UDP communication connection, the read monitoring data is sent to the host computer through the UDP communication connection.

[0040] In some embodiments, a new DBC data volume set and corresponding data processing logic are received from a host computer via a UDP communication connection; If the new DBC data volume set and / or the corresponding data processing logic are different from the pre-stored DBC data volume set and / or the corresponding data processing logic, the pre-stored DBC data volume set and the corresponding data processing logic are deleted, and the new DBC data volume set and the corresponding data processing logic are stored.

[0041] In some embodiments, the present application also provides a dynamic-priority DBC data fragmentation transmission mechanism. This mechanism addresses the issue of insufficient reliability for critical data transmission under the connectionless nature of UDP by dynamically adjusting the transmission strategy based on data importance and network status. Its innovation lies in the deep coupling of data priority and fragmentation strategy, overcoming the limitations of traditional fixed fragmentation models. Specifically, if there are multiple target electronic units, current DBC data from multiple target electronic units can be received in real time. In this case, a dynamic priority determination step is added: transmission priorities are assigned to the different current DBC data received based on the criticality of different target electronic units (e.g., brake system electronic unit data has a higher priority than entertainment system data). For high-priority data, the minimum fragmentation granularity (e.g., 16 bytes / fragment) is used and marked with an "immediate transmission" flag. For low-priority data, an adaptive fragmentation granularity is used (dynamically adjusted to 32-128 bytes / fragment based on network bandwidth). When sending over a UDP communication connection, high-priority fragments are transmitted first. If network congestion is detected, transmission of low-priority fragments is automatically suspended and buffered, and transmission resumes when the network recovers.

[0042] In some embodiments, the UDP communication connection of the present application includes a primary UDP communication connection and a backup UDP communication connection. The real-time monitoring of the UDP communication connection to obtain the monitoring result may include: firstly monitoring the primary UDP communication connection in real time, and if the monitoring result indicates that the primary UDP communication connection is online, transmitting the monitoring data to the host computer through the primary UDP communication connection; If the monitoring result shows that the primary UDP communication connection is offline, the backup UDP communication connection is monitored in real time. If the monitoring result shows that the backup UDP communication connection is online, the monitoring data is transmitted to the host computer through the backup UDP communication connection. If it is detected that the primary UDP communication connection is offline and the backup UDP communication connection is offline, the monitoring data is stored in the configured cache queue.

[0043] The automatic switching and data synchronization mechanism of the primary and backup UDP communication connections in the above implementation can effectively ensure the integrity and real-time performance of data transmission in the event of network instability or failure.

[0044] As can be seen, compared to traditional gateway transparent transmission, which relies heavily on the stability of the communication network, the DBC gateway transparent transmission method based on UDP communication provided in this application optimizes data processing logic, independently processes, calculates, and caches data. This allows for autonomous calculation of control parameters based on different command information, reducing reliance on communication endpoint information and thus maintaining stable system operation even in situations of poor communication quality. Furthermore, this application establishes a transit data processing center to integrate data and user logic, effectively alleviating the drawback of traditional transparent transmission due to its lack of data processing. It also incorporates a cache queue, reducing pressure on communication resources. The addition of user-customized logic allows for dynamic expansion and modification of the content to be transmitted. While traditional transparent transmission technology relies heavily on hardware support, currently, only a transit processing center is required within the traditional transparent transmission module, eliminating the need for hardware support and reducing costs to simply programming the calculation logic. Configuration also requires user configuration within the configuration parameter interface. Furthermore, with limited resources, multiple calculation logics can be distributed from the configuration endpoint. The transit processing center automatically creates calculation logic threads, allowing the data volume of a single packet to be processed simultaneously across multiple asynchronous threads.

[0045] Corresponding to the above method, the embodiment of the present application also provides a DBC gateway transparent transmission device based on UDP communication, such as Figure 3 As shown, the device includes: The receiving unit 310 is configured to receive in real time the current DBC data output by the DBC module and transparently transmitted through the DBC gateway; the current DBC data includes different DBC sub-data corresponding to the target electronic unit; a processing unit 320 configured to process the current DBC data based on a pre-stored DBC data set and corresponding data processing logic to obtain monitoring data of the target electronic unit; the DBC data set and corresponding data processing logic are pre-transmitted by the host computer via the UDP communication connection; The sending unit 330 is used to send the stored monitoring data to the host computer through the UDP communication connection.
