Vehicle Data Transmission via Background Server for Remote Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Car owners cannot obtain real-time vehicle traveling data to ensure safety during vehicle operation using existing vehicle-mounted systems, as the data provided by OBD interfaces is primarily for professional use and not accessible to common users.
Innovation Solution
A method and device that transmit real-time vehicle traveling data from the electronic control unit via a vehicle bus to a background server, enabling remote diagnostic services by reading and processing data through a golo3 connector with DPU and MTK processors, which includes initialization of devices like GPS and Bluetooth, and distinguishes between data that requires a response and data that does not.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If real-time vehicle data is transmitted to background server, then remote diagnostic service is enabled, but data transmission complexity increases
Solution Approach 1:
The patent introduces a background server as an intermediary between the vehicle-mounted device and the user. The background server receives real-time vehicle data from the vehicle-mounted device via wireless communication, processes the data, and provides diagnostic services to users through a terminal device. This intermediary approach enables remote diagnostics without requiring complex direct communication between the vehicle and user terminal.
2Measurement precision
If OBD interface data is provided for professional use only, then data accuracy is maintained, but user accessibility is reduced
Solution Approach 1:
The patent segments the data processing function between the vehicle-mounted device and the background server. The vehicle-mounted device collects raw vehicle data through the OBD interface and transmits it to the background server. The background server then processes, analyzes, and presents the data in a user-friendly format. This segmentation allows professional-grade data collection while providing simplified access to common users.
3Reliability
If vehicle-mounted system provides limited safety conditions, then device simplicity is maintained, but safety monitoring capability is insufficient
Solution Approach 1:
The patent implements a feedback mechanism where the background server continuously receives real-time vehicle data, analyzes safety-related parameters, and provides diagnostic messages back to the user terminal. This feedback loop enables continuous safety monitoring without requiring complex local processing in the vehicle-mounted device, as the analysis is performed remotely on the server.

AI summary
The objective of the present application is to provide a method and device for processing real-time vehicle traveling data, aiming at solving the technical problem that car owners couldn't obtain real-time vehicle traveling data to ensure safety via an existing vehicle-mounted system. The method comprises: obtaining real-time vehicle traveling data from an electronic control unit of the vehicle via a vehicle bus; reading the real-time vehicle traveling data from a serial port; determining whether there is data that needs to be answered in the real-time vehicle traveling data and storing the real-time vehicle traveling data into a data queue whose data need to be answered and a data queue whose data doesn't need to be answered respectively after the determination; transmitting the real-time vehicle traveling data to a background server, so that the background server can provide current vehicle with diagnostic message or service information. Compared with the prior art, the method provided in the embodiment of the present application can provide car owners with remote diagnosis or remote service conveniently, thereby reducing various costs of using cars.
