[0030] Research has found that data collection and diagnosis are important tasks in harvester operation. Data collection and monitoring are important parts of data debugging during harvester testing. In order to record all data, a data acquisition instrument is usually connected to the OBD diagnostic port of the vehicle. However, the data in the data diagnostic instrument can only be viewed after the test is completed. In some projects that require real-time monitoring and debugging, a single OBD diagnostic interface cannot meet the functions of recording and debugging at the same time.

[0031] Based on the above research, the present disclosure provides a vehicle-mounted terminal data transmission system and method, including: a first vehicle-mounted automatic diagnostic interface, a second vehicle-mounted automatic diagnostic interface and a connecting harness; the first vehicle-mounted automatic diagnostic interface and the second vehicle-mounted automatic diagnostic interface are respectively connected to one end of the connecting harness; the other end of the connecting harness is connected to the vehicle control module. By controlling the first vehicle-mounted automatic diagnostic interface, the connecting harness collects vehicle status data, and transmits the vehicle status data to a data diagnostic computer, so that the data diagnostic computer diagnoses the current vehicle status; controlling the second vehicle-mounted automatic diagnostic interface, the connecting harness collects vehicle status data, and transmits the vehicle status data to a data acquisition instrument, so that the data acquisition instrument ensures that the vehicle status data is fully recorded. Vehicle data collection and vehicle status diagnosis can be achieved simultaneously, which improves the convenience of data collection and diagnosis.

[0032] To facilitate understanding of this embodiment, a vehicle terminal data transmission system disclosed in the embodiment of the present disclosure is first described in detail. Figure 1 , which is a schematic diagram of a vehicle terminal data transmission system provided in an embodiment of the present disclosure.

[0033] like Figure 1 As shown in , the first on-board automatic diagnostic interface and the second on-board automatic diagnostic interface are respectively connected to one end of the connecting harness; the other end of the connecting harness is connected to the vehicle control module.

[0034] In the specific implementation, the first on-board automatic diagnosis interface is connected to the data diagnosis computer. The second on-board automatic diagnosis interface is connected to the data acquisition instrument. Designed for the data diagnosis and acquisition interface of harvesting machinery, the single interface is changed to a dual interface, which improves the convenience and practicality of data processing.

[0035] Here, the first on-board automatic diagnosis interface and the second on-board automatic diagnosis interface may be OBD female sockets. The connecting wire harness may be a complete vehicle wire harness of the vehicle.

[0036] Among them, one end of the vehicle wiring harness is connected to two OBD female sockets, and the other end can be connected to the vehicle's display screen, controller, various solenoid valves and other vehicle-mounted or control modules.

[0037] It should be noted that the number of on-board automatic diagnostic interfaces can be multiple.

[0038] In the actual working process, dual OBD interfaces or multiple OBD interfaces are used to connect to the harvester vehicle controller and display screen through wiring harnesses to solve the problem that a single interface cannot simultaneously meet the data collection and diagnosis of the entire vehicle. In this way, one OBD interface can be connected to the data acquisition instrument to ensure the integrity of the data records, and the other OBD interface can be connected to the computer to ensure that the data can be monitored in real time.

[0039] Here, the first onboard diagnostic interface (OBD interface) is connected to the data diagnostic computer to collect the vehicle's status data. This means that the first interface can monitor the various conditions of the vehicle (such as engine temperature, oil pressure, etc.) in real time, and transmit these data to the diagnostic computer for further analysis and fault diagnosis. The second onboard diagnostic interface (OBD interface) is connected to the data acquisition instrument to ensure the complete recording of the vehicle's status data. This means that the second interface can send the collected data to the data acquisition instrument to ensure that no important information is missed during the monitoring process.

[0040] Among them, the first on-board automatic diagnostic interface is responsible for collecting vehicle status data through the connection harness and passing it to the data diagnostic computer to effectively diagnose the current vehicle status. In this way, technicians can obtain and process vehicle information in a timely manner. The second on-board automatic diagnostic interface is also responsible for collecting vehicle status data through the connection harness and passing it to the data acquisition instrument to ensure complete data recording. This design is helpful for subsequent data analysis and troubleshooting.

[0041] Optionally, the vehicle wiring harness can use standard communication protocols (such as CAN bus, LIN bus) for data exchange to ensure compatibility with equipment from different manufacturers. And it integrates a self-test function to detect its own working status and connection stability.

[0042] As a possible implementation, the vehicle wiring harness is responsible for connecting multiple sensors and control modules, and the first on-board automatic diagnostic interface and the second on-board automatic diagnostic interface serve as interfaces for the vehicle's internal electronic system to collect various real-time data. The vehicle wiring harness contains multiple data channels, which can simultaneously collect information from different modules, such as the engine control unit (ECU), transmission system, ABS, etc.

[0043] Furthermore, the second on-board automatic diagnosis interface is connected to the data acquisition instrument to ensure that the data collected from each module of the vehicle is completely recorded. It is responsible for the long-term storage and playback of data, making it easier to find historical data after a fault.

[0044] The second on-board automatic diagnostic interface supports high-frequency data acquisition to ensure that the rapidly changing vehicle status can be accurately recorded. The data logger adopts a large-capacity storage solution to ensure that data recording will not be interrupted due to insufficient storage.

[0045] As another possible implementation, the first on-board automatic diagnostic interface reads data from each sensor periodically or on demand through the vehicle wiring harness. The monitoring frequency can be adjusted according to actual needs to ensure real-time performance. The data diagnostic computer performs preliminary processing on the collected data, including data format conversion and outlier detection, for example, using a filtering algorithm to remove sensor noise to ensure data accuracy. A vehicle status report is generated based on real-time analysis of the received data. Historical data comparison can also be used to identify potential faults and performance issues.

[0046] As another possible implementation, the vehicle terminal data transmission system can automatically generate a fault report, including fault codes, recommended maintenance solutions, and potentially affected components. The report is stored in a database for subsequent query and analysis. If a major fault is found, the system can alert the driver through an audible alarm or dashboard to ensure timely processing.

[0047] In this way, maintenance technicians can quickly obtain vehicle status through the data diagnostic computer, reduce troubleshooting time, and improve maintenance efficiency.

[0048] The disclosed embodiment provides a vehicle terminal data transmission system and method, including: a first vehicle-mounted automatic diagnostic interface, a second vehicle-mounted automatic diagnostic interface and a connecting harness; the first vehicle-mounted automatic diagnostic interface and the second vehicle-mounted automatic diagnostic interface are respectively connected to one end of the connecting harness; the other end of the connecting harness is connected to the vehicle control module. By controlling the first vehicle-mounted automatic diagnostic interface, the connecting harness collects vehicle status data, and transmits the vehicle status data to a data diagnostic computer, so that the data diagnostic computer diagnoses the current vehicle status; by controlling the second vehicle-mounted automatic diagnostic interface, the connecting harness collects vehicle status data, and transmits the vehicle status data to a data acquisition instrument, so that the data acquisition instrument ensures that the vehicle status data is fully recorded. Vehicle data collection and vehicle status diagnosis can be achieved simultaneously, which improves the convenience of data collection and diagnosis.
