Description

Technical Field

[0001] This application relates to the field of data processing, and in particular to an in-vehicle Ethernet data conversion device and an in-vehicle Ethernet data conversion method. Background Technology

[0002] With the development of intelligent and connected vehicles, the amount of data to be transmitted inside vehicles is increasing, and the required transmission bandwidth is also increasing. The transmission bandwidth provided by traditional in-vehicle transmission protocols is difficult to meet the bandwidth requirements for transmitting large amounts of data. Therefore, in-vehicle Ethernet, which is dedicated to in-vehicle data transmission, has emerged.

[0003] Traditional vehicle-mounted data exchange equipment, when multiple vehicle-mounted Ethernet channels need to transmit data simultaneously, can connect to the test terminal through multiple single-channel vehicle-mounted Ethernet to industrial Ethernet adapter boards to perform Ethernet data transmission and data testing.

[0004] However, when converting between multi-channel automotive Ethernet and industrial Ethernet, the independent nature of each hardware device leads to complex wiring operations, multiple wiring operations, and large space requirements. Furthermore, the voltage difference between the automotive Ethernet to industrial Ethernet adapter board and the ground plane of the test terminal causes Ethernet connection interruptions, resulting in unstable multi-channel data testing of automotive Ethernet. Summary of the Invention

[0005] Therefore, it is necessary to provide an in-vehicle Ethernet data conversion device, method, computer equipment, computer-readable storage medium, and computer program product that can reduce the operational difficulty and device footprint when converting between multiple in-vehicle Ethernet and industrial Ethernet.

In one embodiment, after receiving the test results from the data processing module for each of the Ethernet data conversion modules, the method further includes:

[0022] If the test results of any of the Ethernet data conversion modules indicate that the Ethernet data conversion module is unavailable, a backup Ethernet data conversion module corresponding to the Ethernet data conversion module shall be determined from the remaining Ethernet data conversion modules.

[0023] Upon receiving vehicle Ethernet data to be transmitted to any of the Ethernet data conversion modules, if there is a corresponding backup Ethernet data conversion module, the vehicle Ethernet data to be transmitted to the Ethernet data conversion module will be transmitted to the backup Ethernet data conversion module.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0046] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0049] like Figure 1 As shown in the figure, this application provides an in-vehicle Ethernet data conversion device. The in-vehicle Ethernet data conversion device includes multiple in-vehicle Ethernet interfaces, a data switching module, multiple Ethernet data conversion modules, and a data processing module.

[0050] The system includes multiple vehicle-mounted Ethernet interfaces, each used to receive vehicle-mounted Ethernet data. This data can be any data to be transmitted within the vehicle, such as vehicle logs; this application does not limit the type of vehicle-mounted Ethernet data. A data switching module is used to input the vehicle-mounted Ethernet data received through each interface to its corresponding Ethernet data conversion module. Multiple Ethernet data conversion modules are used to convert the received vehicle-mounted Ethernet data into industrial Ethernet data and transmit the industrial Ethernet data to a data processing module. The data processing module performs testing on each Ethernet data conversion module based on the received industrial Ethernet data, obtaining test results for each module.

[0051] There is no specific limit to the number of vehicle Ethernet interfaces and Ethernet data conversion modules in the vehicle Ethernet data conversion device, and the vehicle Ethernet data conversion device can be a portable and detachable device.

[0052] In this embodiment, the data processing module has multiple industrial Ethernet interfaces. An Ethernet data conversion module is used to convert the vehicle-mounted Ethernet protocol (100base-T1) to the industrial Ethernet protocol (100base-TX), or vice versa, to ensure that data from two different protocols inside and outside the device can be quickly converted and correctly identified. The Ethernet data conversion module may include an Ethernet conversion chip for converting vehicle-mounted Ethernet to industrial Ethernet. For example, the Ethernet data conversion module may include a vehicle-mounted Ethernet port physical layer PHY chip and an industrial Ethernet PHY chip. The first end of each Ethernet data conversion module is electrically connected to the corresponding industrial Ethernet interface of the data processing module, and the second end of each Ethernet data conversion module is electrically connected to the data switching module. After receiving the industrial Ethernet data, the data processing module can, according to actual usage requirements, use pre-installed software tools or programs to perform functions such as network connectivity testing, network data transmission rate testing, and network load testing, and obtain the test results.

[0053] Any software tool or program that can perform test processing on Ethernet data can be used in this application, and the embodiments of this application do not limit this.

[0054] For the specific structure of the data processing module, please refer to Figure 2As shown, the data processing module includes a central processing unit (CPU), memory chips, an industrial Ethernet PHY chip, and a data storage unit. For example, the CPU in the data processing module can be a chip such as BCM2711 or STM32MP157, used to run software tools or programs to process data; the memory chips can be DDR3 or DDR4 memory chips, and to consider that the data processing module may simultaneously receive a large amount of industrial Ethernet data during testing, memory chips with a storage capacity greater than or equal to the preset memory size can be selected, such as 2GB memory chips; the data storage unit can be a TF (TransFlash) card, and to consider that after the data processing module performs testing, it may store and process a large amount of industrial Ethernet data through pre-installed software tools or programs, a TF card with a storage capacity greater than or equal to the preset memory size can be selected, such as a 32GB TF card.

[0055] The data processing module also includes an industrial Ethernet circuit and an industrial Ethernet interface. The industrial Ethernet circuit can be an industrial Ethernet circuit composed of an industrial Ethernet PHY chip and peripheral circuitry, used to transmit industrial Ethernet data to the central processing unit. The industrial Ethernet interface can be composed of the interface for the data processing module to connect to the network cable and protection circuitry. It is understood that any structure and module with data processing capabilities can be applied to the data processing module in this application embodiment. This application embodiment does not limit the specific structure of the data processing module. Figure 2 This is only one exemplary embodiment.

[0056] When two vehicle Ethernet interfaces transmit data directly, one device with a vehicle Ethernet interface needs to be set to master mode and the other device with a vehicle Ethernet interface needs to be set to slave mode for data transmission. The DIP switch is used to switch between master and slave modes. Therefore, the Ethernet data conversion module can also be equipped with a DIP switch to receive vehicle Ethernet data from each vehicle Ethernet interface when the vehicle Ethernet data conversion device is connected to the vehicle's vehicle Ethernet interface.

[0057] The vehicle-mounted Ethernet data conversion device is also equipped with a power supply module, which obtains power through a power interface to provide power to the data switching module, the Ethernet data conversion module, and the data processing module.

[0058] The aforementioned vehicle-mounted Ethernet data conversion device uses multiple vehicle-mounted Ethernet interfaces to receive various vehicle-mounted Ethernet data. A data switching module inputs the received vehicle-mounted Ethernet data from each interface to its corresponding Ethernet data conversion module. Multiple Ethernet data conversion modules convert the received vehicle-mounted Ethernet data into industrial Ethernet data and transmit the industrial Ethernet data to a data processing module. The data processing module performs testing on each Ethernet data conversion module based on the received industrial Ethernet data, obtaining test results for each module. Because the vehicle-mounted Ethernet data conversion device integrates the multi-route data processing module, Ethernet data conversion module, data switching module, and routing module into a single circuit, it eliminates the need for extensive external wiring. This reduces the operational difficulty and device footprint when converting between multiple vehicle-mounted Ethernet and industrial Ethernet signals. Furthermore, since it eliminates the need for a vehicle-mounted Ethernet to industrial Ethernet adapter board, it overcomes the problem of unstable multi-channel vehicle Ethernet data testing caused by voltage differences between the vehicle-mounted Ethernet adapter board and the ground plane of the test terminal, which can lead to Ethernet connection interruptions.

[0059] In one embodiment, such as Figure 3 As shown, the above-mentioned device also includes a routing module and an Ethernet data conversion module, which are further used to transmit industrial Ethernet data to the routing module. The routing module is used to transmit the industrial Ethernet data transmitted by each Ethernet data conversion module to the data processing module through the corresponding ports of each Ethernet data conversion module.

[0060] In this embodiment, the routing module may have multiple ports. The routing module can be connected to the first end of each Ethernet data conversion module and the data processing module through the multiple ports via network cables, and is used to transmit the industrial Ethernet data transmitted through each Ethernet data conversion module to the data processing module.

[0061] The routing module can also, based on the industrial Ethernet data transmitted on each port, find the destination IP address corresponding to the source Internet Protocol address (IP address) of each industrial Ethernet data transmission, and then find the corresponding port of the routing module connected to the data processing module based on the destination IP address. The industrial Ethernet data is then forwarded to the corresponding port of the data processing module. The data processing module then distinguishes the data sent by different Ethernet data conversion modules based on the IP address.

[0062] The data processing module is also used to obtain the Ethernet data conversion module to which each industrial Ethernet belongs based on the Internet Protocol address of the industrial Ethernet data sent by the routing module. The first end of each Ethernet data conversion module is connected to the port corresponding to the routing module via a network cable, and the second end of each Ethernet data conversion module is electrically connected to the data switching module.

[0063] The power supply module provides power to the routing module and the data processing module through a first power supply module equipped with a low-dropout linear voltage regulator circuit.

[0064] In this embodiment, the industrial Ethernet data transmitted by each Ethernet data conversion module is transmitted to the data processing module through the routing module. The data processing module can distinguish the data sent by different Ethernet data conversion modules by IP address, which facilitates the subsequent testing and processing of each Ethernet data conversion module and the determination of the corresponding backup Ethernet data conversion module based on the IP address of each Ethernet data conversion module.

[0065] In one embodiment, the data processing module is further configured to send test results for each Ethernet data conversion module to the data switching module; the data switching module is further configured to determine the Ethernet data conversion module corresponding to each vehicle Ethernet interface based on the test results for each Ethernet data conversion module.

[0066] In this embodiment of the application, the data processing module can also send the test results for each Ethernet data conversion module to the data switching module. After receiving the test results, the data switching module can redetermine the Ethernet data conversion module corresponding to each vehicle Ethernet interface based on the availability status of each Ethernet data conversion module in the test results.

[0067] The test results may include high availability, medium availability, low availability, and unavailable states, which respectively represent the available status of the corresponding Ethernet data conversion module. The above test results are merely an example of test results in this embodiment and should not be construed as limiting the test results. In fact, the test results can be further categorized by those skilled in the art as needed, with more coarse or fine granularity. This embodiment does not specifically limit the method of categorizing the test results.

[0068] In this embodiment, after receiving the test results, the data switching module can process each Ethernet data conversion module based on the availability status of each module in the test results. Even when the availability of a particular Ethernet data conversion module is poor, the module can re-determine the corresponding Ethernet data conversion module for each vehicle Ethernet interface. This improves the reliability of the vehicle Ethernet data conversion device during user operation.

[0069] In one embodiment, the data switching module is further configured to, when the test results of any Ethernet data conversion module indicate that the Ethernet data conversion module is unavailable, determine the backup Ethernet data conversion module corresponding to the Ethernet data conversion module from the remaining Ethernet data conversion modules, and transmit the vehicle Ethernet data to be transmitted to the Ethernet data conversion module to the backup Ethernet data conversion module.

[0070] The power supply module provides power to the data switching module and the Ethernet data conversion module through a second power supply module equipped with a step-down conversion circuit.

[0071] In this embodiment of the application, if the test result of any Ethernet data conversion module indicates that the Ethernet data conversion module is in an unavailable state, the data processing module can compare the test results of all Ethernet data conversion modules and determine the backup Ethernet data conversion module corresponding to the remaining Ethernet data conversion modules.

[0072] For example, in a vehicle-mounted Ethernet data conversion device comprising three Ethernet data conversion modules, namely Ethernet data conversion module B1, Ethernet data conversion module B2, and Ethernet data conversion module B3, the data processing module can compare the test results of all Ethernet data conversion modules to determine that Ethernet data conversion module B1 is unavailable, Ethernet data conversion module B2 is highly available, and Ethernet data conversion module B3 is low available. The data processing module compares the availability status of each Ethernet data conversion module and uses Ethernet data conversion module B2, which has a higher availability status, as a backup Ethernet data conversion module for B1. Then, the data switching module, based on the backup Ethernet data conversion module corresponding to the selected module, transmits the vehicle-mounted Ethernet data to be transmitted to the backup Ethernet data conversion module.

[0073] Optionally, if the test results of any Ethernet data conversion module indicate that the Ethernet data conversion module is in a low availability state, the data processing module can also determine the backup Ethernet data conversion module corresponding to that Ethernet data conversion module from the remaining Ethernet data conversion modules.

[0074] In this embodiment, when the availability of a certain Ethernet data conversion module is poor, a backup Ethernet data conversion module can be determined from the Ethernet data conversion modules with better availability, thereby improving the reliability and traceability of the vehicle-mounted Ethernet data conversion device during user operation.

[0075] In one embodiment, the data switching module is further configured to determine the backup Ethernet data conversion module corresponding to the Ethernet data conversion module from the remaining Ethernet data conversion modules based on the test results of each remaining Ethernet data conversion module and the data switching conditions.

[0076] The data switching condition is that the test results of each remaining Ethernet data conversion module are better than the current Ethernet data conversion module; the current Ethernet data conversion module is an Ethernet data conversion module that is in an unavailable state.

[0077] In this embodiment of the application, if the test results of a remaining Ethernet data conversion module are better than the test results of the current Ethernet data conversion module, the data switching module determines the backup Ethernet data conversion module corresponding to the current Ethernet data conversion module from the remaining Ethernet data conversion modules.

[0078] In this embodiment, a backup Ethernet data conversion module that is better than the test results of the current Ethernet data conversion module can be determined from the remaining Ethernet data conversion modules according to the data switching conditions. When the current Ethernet data conversion module is unavailable, a backup Ethernet data conversion module can be selected, which improves the reliability of the vehicle-mounted Ethernet data conversion device during user operation.

[0079] In one embodiment, the data processing module is further configured to send test results for each Ethernet data conversion module to the vehicle terminal, so that the vehicle terminal can display the test results on the display interface.

[0080] The vehicle-mounted terminal is a device with a display function, which can display the processing process in the data processing module. The data processing module is electrically connected to the vehicle-mounted terminal.

[0081] In this embodiment, the data processing module sends test results for each Ethernet data conversion module to the vehicle terminal. The vehicle terminal displays the test results on a display interface so that the user can know the test results of each Ethernet data conversion module. The vehicle terminal can display detailed information based on the test results. For example, the vehicle terminal can display detailed parameters of the test results for each Ethernet data conversion module, such as network connectivity status, network data transmission rate, and the load status of the Ethernet data conversion module. This embodiment does not limit the detailed information provided in the test results.

[0082] Then, users can customize the backup Ethernet data conversion modules of each Ethernet data conversion module based on the vehicle terminal. Optionally, the data processing module is electrically connected to the vehicle terminal, and users can perform routine data processing on each vehicle Ethernet data based on the vehicle terminal and the data processing module. This application does not limit the method of data processing.

[0083] In this embodiment, the vehicle-mounted terminal displays the test results of each Ethernet data conversion module in a personalized manner on the interface, allowing users to understand the test results of each Ethernet data conversion module. Furthermore, users can personalize the backup Ethernet data conversion modules for each Ethernet data conversion module based on the vehicle-mounted terminal.

[0084] In one embodiment, the device further includes a circuit board on which the vehicle Ethernet interface, data switching module, Ethernet data conversion module, routing module and data processing module are integrated.

[0085] In this embodiment, the vehicle-mounted Ethernet interface, data switching module, Ethernet data conversion module, routing module, and data processing module can be directly electrically connected via internal wires on the circuit board. Optionally, the vehicle-mounted Ethernet interface, data switching module, Ethernet data conversion module, routing module, and data processing module can also be independently mounted on different circuit boards, with their respective grounding terminals electrically connected.

[0086] In this embodiment, since the vehicle Ethernet interface, data switching module, Ethernet data conversion module, routing module and data processing module are integrated on the circuit board, a large number of external wirings are not required, which reduces the operational difficulty and the area occupied by the device when converting between multiple vehicle Ethernet and industrial Ethernet.

[0087] Based on the same inventive concept, this application also provides an in-vehicle Ethernet data conversion device applied to the aforementioned in-vehicle Ethernet data conversion device. The solution provided by this method is similar to the solution described in the above-described device; therefore, the specific limitations in one or more in-vehicle Ethernet data conversion method embodiments provided below can be found in the limitations of the in-vehicle Ethernet data conversion device described above, and will not be repeated here.

[0088] In one embodiment, an in-vehicle Ethernet data conversion method is provided, which is applied to a data switching module in an in-vehicle Ethernet data conversion device, such as... Figure 4 As shown, the in-vehicle Ethernet data conversion method includes:

[0089] Step 402: Receive vehicle Ethernet data transmitted from each vehicle Ethernet interface.

[0090] In this embodiment of the application, the data switching module receives vehicle Ethernet data transmitted by each vehicle Ethernet interface in the vehicle Ethernet data conversion device connected to each vehicle Ethernet interface in the vehicle.

[0091] Step 404: Based on the mapping relationship between each vehicle Ethernet interface and each Ethernet data conversion module, input the vehicle Ethernet data transmitted by each vehicle Ethernet interface into the corresponding Ethernet data conversion module for testing.

[0092] The mapping relationship between each vehicle Ethernet interface and each Ethernet data conversion module can be determined according to the actual application. This application embodiment does not limit the mapping relationship between each vehicle Ethernet interface and each Ethernet data conversion module. For example, the vehicle Ethernet interfaces include vehicle Ethernet interfaces A1, A2, and A3, and the Ethernet data conversion modules include B1, B2, and B3. The mapping relationship between each vehicle Ethernet interface and each Ethernet data conversion module is A1 to B1, A2 to B2, and A3 to B3.

[0093] In this embodiment, the data switching module, through a pre-set mapping relationship between each vehicle Ethernet interface and each Ethernet data conversion module, inputs the vehicle Ethernet data transmitted by each vehicle Ethernet interface into the corresponding Ethernet data conversion module. Each Ethernet data conversion module converts the vehicle Ethernet data sent by the data switching module into industrial Ethernet data. Then, the data processing module performs test processing on the Ethernet data conversion modules based on the industrial Ethernet data.

[0094] Step 406: Receive the test results from the data processing module for each Ethernet data conversion module.

[0095] The test results are used to characterize the availability of each Ethernet data conversion module.

[0096] In this embodiment, the data switching module receives the test results from the data processing module for each Ethernet data conversion module.

[0097] The vehicle Ethernet data conversion method provided in this application embodiment allows for the reception of various vehicle Ethernet data through multiple vehicle Ethernet interfaces. A data switching module inputs the received vehicle Ethernet data from each interface to a corresponding Ethernet data conversion module. Multiple Ethernet data conversion modules convert the received vehicle Ethernet data into industrial Ethernet data and transmit the industrial Ethernet data to a data processing module. The data processing module performs testing on each Ethernet data conversion module based on the received industrial Ethernet data, obtaining test results for each module. Since the vehicle Ethernet data conversion device integrates the multi-route data processing module, Ethernet data conversion module, data switching module, and routing module into a single circuit, it eliminates the need for extensive external wiring. This reduces the operational difficulty and device footprint when converting between multiple vehicle Ethernet and industrial Ethernet streams. Furthermore, because it eliminates the need for a vehicle Ethernet to industrial Ethernet adapter board, it overcomes the problem of unstable multi-channel vehicle Ethernet data testing caused by voltage differences between the vehicle Ethernet adapter board and the ground plane of the test terminal, which can lead to Ethernet connection interruptions.

[0098] In one embodiment, such as Figure 5 As shown, after step 406, the following steps are also included:

[0099] Step 502: If the test result of any Ethernet data conversion module indicates that the Ethernet data conversion module is unavailable, determine the backup Ethernet data conversion module corresponding to the remaining Ethernet data conversion modules.

[0100] In this embodiment of the application, if the test result of any Ethernet data conversion module indicates that the Ethernet data conversion module is in an unavailable state, the data processing module can compare the test results of all Ethernet data conversion modules and determine the backup Ethernet data conversion module corresponding to the remaining Ethernet data conversion modules.

[0101] Optionally, if the test results of any Ethernet data conversion module indicate that the Ethernet data conversion module is in a low availability state, the data processing module can also determine the backup Ethernet data conversion module corresponding to that Ethernet data conversion module from the remaining Ethernet data conversion modules.

[0102] Step 504: Upon receiving the vehicle Ethernet data to be transmitted to the Ethernet data conversion module, if there is a corresponding backup Ethernet data conversion module, the vehicle Ethernet data to be transmitted to the Ethernet data conversion module will be transmitted to the backup Ethernet data conversion module.

[0103] In this embodiment, the data switching module changes the mapping relationship between each vehicle Ethernet interface and each Ethernet data conversion module according to the backup Ethernet data conversion module corresponding to the Ethernet data conversion module, and transmits the vehicle Ethernet data to be transmitted to the Ethernet data conversion module to the backup Ethernet data conversion module.

[0104] In one embodiment, step 502 includes:

[0105] Based on the test results and data switching conditions of each remaining Ethernet data conversion module, the backup Ethernet data conversion module corresponding to the remaining Ethernet data conversion module is determined.

[0106] The data switching condition is that the test results of each remaining Ethernet data conversion module are better than the current Ethernet data conversion module.

[0107] In this embodiment of the application, if the test results of a remaining Ethernet data conversion module are better than the test results of the current Ethernet data conversion module, the data switching module determines the backup Ethernet data conversion module corresponding to the current Ethernet data conversion module from the remaining Ethernet data conversion modules.

[0108] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages.
