[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] The following is combined with Figures 1-4 The present invention describes a data processing method, apparatus, and electronic device for vehicle-mounted equipment.

[0022] Figure 1 This is one of the flowcharts illustrating the data processing method for in-vehicle equipment provided by the present invention, such as... Figure 1 As shown, the data processing method for vehicle-mounted equipment is applied to the main data processing subsystem and includes steps S100 to S400, each of which is detailed below.

[0023] S100: Within the current time period, acquire the first external network data and the first internal network data of the vehicle-mounted device.

[0024] The subject of this invention is a data processing system for in-vehicle equipment. This system includes two independent main data processing subsystems and a backup data processing subsystem, enabling data synchronization and backup for the in-vehicle equipment. When the main data processing subsystem malfunctions or encounters a problem, the backup data processing subsystem can take over the task, ensuring the continuous operation of the in-vehicle equipment's data processing system and the security and integrity of the data.

[0025] The data processing method for vehicle-mounted equipment of the present invention adopts a dual-system synchronization scheme to improve the reliability and stability of the data processing system of vehicle-mounted equipment.

[0026] Within the current time period, the main data processing subsystem receives data from the external network (e.g., vehicle-to-ground network) corresponding to the onboard equipment, obtaining first external network data. Simultaneously, the backup data processing subsystem also receives data from the external network corresponding to the onboard equipment, obtaining second external network data. The first and second external network data are essentially identical.

[0027] During the current time period, the primary data processing subsystem receives internal communication data from the vehicle-mounted equipment, obtaining the first internal network data. Simultaneously, the backup data processing subsystem also receives internal communication data from the vehicle-mounted equipment, obtaining the second internal network data. The first and second internal network data are essentially identical.

[0028] S200: Within the current time period, acquire the vehicle hardwire data of the on-board equipment and send the vehicle hardwire data to the backup data processing subsystem, so that the backup data processing subsystem can execute the backup logic task of the current time period based on the vehicle hardwire data, the second external network data and the second internal network data, and obtain the backup processing result.

[0029] In one embodiment, the first external network data or the second external network data includes ground area controller data, integrated monitoring data, and computer interlocking data; the first internal network data or the second internal network data includes train automatic driving data, transponder transmission system data, and human-machine interaction unit data; and the vehicle hardwired data includes vehicle feedback data, driver button operation data, and speed and distance measurement data.

[0030] The first or second external network data includes data from the vehicle-to-ground network, such as Zone Controller (ZC) data, Train Integrated Supervisory and Control System (TIAS) data, and Computer Interlocking (CI) data.

[0031] The first or second internal network data includes Automatic Train Operation (ATO) data, Balise Transmission Module (BTM) data, and Man-Machine Interface (MMI) data.

[0032] Vehicle hardline data includes vehicle feedback data, driver button operation data, and speed and distance measurement data.

[0033] Within the current time period, the primary data processing subsystem acquires vehicle hardwire data, then packages this data and sends it to the backup data processing subsystem via the synchronization channel between the primary and backup data processing subsystems. This ensures complete consistency between the vehicle hardwire data used by the primary and backup data processing subsystems. Upon receiving the vehicle hardwire data, the backup data processing subsystem executes the backup logic task for the current time period based on the vehicle hardwire data, the second external network data, and the second internal network data, obtaining the backup processing result.

[0034] S300: Based on the first external network data, the first internal network data, and the vehicle hardwire data, execute the main logic task for the current time period and obtain the main processing result.

[0035] The chip of the main data processing subsystem performs calculations based on the first external network data, the first internal network data, and the vehicle hardwire data, executes the main logic task of the current time period, and obtains the main processing result.

[0036] S400: Based on the security protocol synchronization data parsing master processing result, obtain the master data parsing result of the vehicle device for the current time period, and send the security protocol synchronization data to the backup data processing subsystem, so that the backup data processing subsystem can parse the backup processing result based on the security protocol synchronization data to obtain the backup data parsing result for the current time period. The backup data parsing result is used to verify whether the master data parsing result is accurate.

[0037] After the main data processing subsystem completes the main logic task for the current time period, it acquires security protocol synchronization data (Railway Safety Signaling Protocol Interface, or RSSP), such as RSSPI or RSSPII. Security protocol synchronization data includes static variables, such as whether the time series of the first external network data is active.

[0038] The main data processing subsystem synchronizes the data and parses the main processing results according to the security protocol to obtain the main data parsing result for the current time period of the on-board device. Simultaneously, the main data processing subsystem sends the security protocol synchronization data to the backup data processing subsystem through the synchronization channel. The backup data processing subsystem receives the security protocol synchronization data and assigns it to its own security protocol, thus ensuring that within the same time period, the main data processing subsystem and the backup data processing subsystem use the same security protocol synchronization data and perform the same network data parsing.

[0039] During the normal operation of the vehicle-mounted equipment's data processing system, after the data processing for the current time period is completed, the master data parsing result and the backup data parsing result are compared. If the master data parsing result and the backup data parsing result are consistent, it indicates that the master data parsing result is accurate, and only the master data parsing result is output externally.

[0040] The data processing method for in-vehicle equipment provided in this invention ensures that the same vehicle hardwired data is input between the main data processing subsystem and the backup data processing subsystem by synchronizing vehicle hardwired data, which is beneficial to improving the data processing efficiency of the in-vehicle equipment. By synchronizing data using a security protocol, it ensures that the main data processing subsystem and the backup data processing subsystem execute the same logical tasks based on the same security protocol, which is also beneficial to improving the data processing efficiency of the in-vehicle equipment. Furthermore, this invention verifies the main data parsing results based on the backup data parsing results, thereby improving the reliability and stability of the in-vehicle equipment's data processing system.

[0041] Based on the above embodiments, acquiring the first external network data and the first internal network data of the vehicle-mounted device within the current time period includes the following steps: Within the current time period, the first external network data is acquired based on the preset first timestamp and the preset board; wherein, the backup data processing subsystem acquires the second external network data based on the preset first timestamp and the preset board to ensure that the first external network data is consistent with the second external network data; Within the current time period, first internal network data is acquired based on a preset second timestamp; wherein, the backup data processing subsystem acquires second internal network data based on the preset second timestamp to ensure that the first internal network data and the second internal network data are consistent.

[0042] The first timestamp is preset to be the start time for collecting the first external network data and the second external network data. The preset board is the board for acquiring the first internal network data and the second internal network data.

[0043] Within the current time period, the main data processing subsystem and the backup data processing subsystem simultaneously obtain essentially consistent external network data based on the first timestamp and the preset board, thus obtaining the first external network data and the second external network data.

[0044] Within the current time period, the main data processing subsystem and the backup data processing subsystem simultaneously obtain essentially consistent internal network data based on the second timestamp, thus obtaining the first internal network data and the second internal network data.

[0045] This invention ensures consistency of external network data collected by the main data processing subsystem and the backup data processing subsystem based on a preset first timestamp and a preset board. This invention also ensures consistency of internal network data collected by the main data processing subsystem and the backup data processing subsystem based on a preset second timestamp.

[0046] Based on the above embodiments, the system obtains the master data parsing result of the vehicle device for the current time period based on the master processing result of the security protocol synchronization data parsing, and sends the security protocol synchronization data to the backup data processing subsystem so that the backup data processing subsystem can parse the backup processing result based on the security protocol synchronization data to obtain the backup data parsing result for the current time period. The system further includes: in the next time period, obtaining the master data parsing result of the vehicle device for the next time period based on the master data parsing result of the current time period.

[0047] After obtaining the master data parsing result for the current time period, the master data processing subsystem performs data processing on the vehicle-mounted equipment for the next time period based on the master data parsing result for the current time period, and obtains the master data parsing result for the next time period.

[0048] Meanwhile, after the backup data processing subsystem obtains the backup data parsing result for the current time period, it performs data processing on the vehicle-mounted equipment for the next time period based on the backup data parsing result for the current time period, thereby obtaining the backup data parsing result for the next time period. This ensures that in the next time period, the main data processing subsystem and the backup data processing subsystem can perform the same logical tasks and obtain the same data parsing results when the input internal network data and external network data are completely consistent.

[0049] For example, the master data processing subsystem acquires the first external network data and the first internal network data of the in-vehicle device for the next time period. It then acquires the vehicle hardwire data of the in-vehicle device for the next time period and, based on the first external network data, the first internal network data, the vehicle hardwire data, and the master data parsing result of the current time period, executes the main logic task for the next time period to obtain the master processing result for the next time period. Finally, the master data processing subsystem synchronizes the data parsing of the master processing result for the next time period according to the security protocol to obtain the master data parsing result of the in-vehicle device for the next time period.

[0050] This invention obtains the master data parsing result for the next time period based on the master data parsing result of the current time period, ensuring the integrity and consistency of data processing for the vehicle-mounted equipment.

[0051] Based on the above embodiments, the main data processing subsystem includes a first chip and a second chip. Based on first external network data, first internal network data, and vehicle hardwire data, it executes the main logic task for the current time period to obtain the main processing result, including the following steps: The first chip performs calculations on the first external network data, the first internal network data, and the vehicle hardwire data to execute the main logic task of the current time period and obtain the first processing result. The second chip performs calculations on the first external network data, the first internal network data, and the vehicle hardwire data to execute the main logic task of the current time period and obtain the second processing result. When the first processing result and the second processing result are consistent, the main processing result is obtained based on the first processing result or the second processing result.

[0052] The main data processing subsystem employs a two-out-of-two design, comprising a first chip and a second chip. Within the same time period, both chips execute the same main logic task. The first chip processes the first external network data, the first internal network data, and the vehicle hardwire data, executing the main logic task for the current time period to obtain a first processing result. The second chip processes the first external network data, the first internal network data, and the vehicle hardwire data, executing the main logic task for the current time period to obtain a second processing result. When the first and second processing results are identical, either the first or second processing result is output, yielding the main processing result.

[0053] This invention improves the accuracy of obtaining the main processing result by having the first chip and the second chip perform the same main logic task and obtain the first processing result and the second processing result.

[0054] This invention provides a data processing method for an in-vehicle device, applied to a backup data processing subsystem, including steps S500 to S900, each step of which is detailed below.

[0055] S500: Within the current time period, acquire the second external network data and the second internal network data of the vehicle-mounted equipment.

[0056] During the current time period, the backup data processing subsystem receives data from the external network (e.g., vehicle-to-ground network) corresponding to the onboard equipment, obtaining second external network data. Simultaneously, the main data processing subsystem receives data from the external network corresponding to the onboard equipment, obtaining first external network data. The first and second external network data are essentially identical.

[0057] During the current time period, the backup data processing subsystem receives internal communication data from the vehicle-mounted equipment and obtains second internal network data. Simultaneously, the main data processing subsystem receives internal communication data from the vehicle-mounted equipment and obtains first internal network data. The first and second internal network data are essentially identical.

[0058] S600: During the current time period, receive vehicle hardwire data from the on-board equipment sent by the main data processing subsystem.

[0059] Within the current time period, the primary data processing subsystem acquires vehicle hardwire data, then packages the vehicle hardwire data and sends it to the backup data processing subsystem through the synchronization channel between the primary data processing subsystem and the backup data processing subsystem, thereby ensuring that the vehicle hardwire data used by the primary data processing subsystem and the backup data processing subsystem are completely consistent.

[0060] S700: Based on vehicle hardwire data, second external network data, and second internal network data, execute the backup logic task for the current time period and obtain the backup processing result.

[0061] The main data processing subsystem executes the main logic task for the current time period based on the first external network data of the vehicle equipment, the first internal network data of the vehicle equipment, and the vehicle hardwire data, and obtains the main processing result.

[0062] After receiving the vehicle hardwire data, the backup data processing subsystem executes the backup logic task for the current time period based on the vehicle hardwire data, the second external network data, and the second internal network data, and obtains the backup processing result.

[0063] The chip of the main data processing subsystem performs calculations based on the first external network data, the first internal network data, and the vehicle hardwire data, executes the main logic task of the current time period, and obtains the main processing result.

[0064] S800: Receives security protocol synchronization data sent by the main data processing subsystem.

[0065] After completing the main logic tasks for the current time period, the primary data processing subsystem acquires security protocol synchronization data. It then sends this data to the backup data processing subsystem via a synchronization channel. The backup subsystem receives the synchronization data and assigns it to its own security protocol, ensuring that both systems use the same synchronization data and perform the same network data parsing within the same time period.

[0066] S900: Based on the security protocol, synchronize the data parsing backup processing results to obtain the backup data parsing results for the current time period.

[0067] The master data processing subsystem synchronizes the data parsing master processing results based on the security protocol to obtain the master data parsing results of the vehicle-mounted device for the current time period. The backup data parsing results are used to verify whether the master data parsing results are accurate.

[0068] The backup data processing subsystem synchronizes the data parsing backup processing results according to the security protocol to obtain the backup data parsing results for the current time period.

[0069] The master data processing subsystem synchronizes the data parsing master processing results according to the security protocol and obtains the master data parsing results of the vehicle-mounted device for the current time period.

[0070] Compare the master data parsing result with the backup data parsing result. If the master data parsing result and the backup data parsing result are consistent, it means that the master data parsing result is accurate, and only the master data parsing result is output.

[0071] The data processing method for in-vehicle equipment provided in this invention ensures that the same vehicle hardwired data is input between the main data processing subsystem and the backup data processing subsystem by synchronizing vehicle hardwired data, which is beneficial to improving the data processing efficiency of the in-vehicle equipment. By synchronizing data using a security protocol, it ensures that the main data processing subsystem and the backup data processing subsystem execute the same logical tasks based on the same security protocol, which is also beneficial to improving the data processing efficiency of the in-vehicle equipment. Furthermore, this invention verifies the main data parsing results based on the backup data parsing results, thereby improving the reliability and stability of the in-vehicle equipment's data processing system.

[0072] Based on the above embodiments, after obtaining the backup data parsing result of the vehicle device for the current time period based on the backup data parsing processing result of the security protocol synchronization data, the method further includes: in the next time period, obtaining the backup data parsing result of the vehicle device for the next time period based on the backup data parsing result of the current time period.

[0073] After obtaining the backup data parsing result for the current time period, the backup data processing subsystem performs data processing on the vehicle-mounted equipment for the next time period based on the backup data parsing result for the current time period, and obtains the backup data parsing result for the next time period.

[0074] For example, the backup data processing subsystem acquires the second external network data and the second internal network data of the on-board equipment for the next time period. The backup data processing subsystem receives the vehicle hardwire data of the on-board equipment for the next time period sent by the main data processing subsystem, and executes the backup logic task for the next time period based on the second external network data, the second internal network data, the vehicle hardwire data, and the backup data parsing result of the current time period, obtaining the backup processing result for the next time period. The backup data processing subsystem synchronously parses the backup processing result for the next time period according to the security protocol, and obtains the backup data parsing result for the on-board equipment for the next time period.

[0075] This invention obtains the backup data analysis results for the next time period based on the backup data analysis results for the current time period, ensuring the integrity and consistency of data processing for the vehicle-mounted equipment.

[0076] The data processing system for the vehicle-mounted device provided by the present invention is described below. The data processing system for the vehicle-mounted device described below can be referred to in correspondence with the data processing method for the vehicle-mounted device described above.
