Description

Technical Field

[0001] The invention relates to the technical field of motor vehicles, in particular to a vehicle fault monitoring and maintenance system. Background Art

[0002] With the rapid development of the automobile industry, the performance and functions of vehicles are becoming increasingly complex, and the role of on-board electronic systems in vehicle operation is becoming increasingly important. In order to monitor the operating status of the vehicle in real time, the on-board diagnostic system (OBD) is widely used in various models. The OBD system collects various operating parameters and fault information of the vehicle to help maintenance personnel perform fault diagnosis and maintenance guidance, thereby improving maintenance efficiency and vehicle operation reliability.

[0003] At present, data acquisition technology based on OBD ports has been applied in the field of vehicle fault monitoring and maintenance guidance. This type of technology usually collects vehicle operation data in real time through a data acquisition module installed on the vehicle's OBD port, and uploads this data to the intelligent maintenance guidance cloud platform. The cloud platform analyzes and processes this data to provide maintenance personnel with targeted maintenance guidance, thereby achieving rapid diagnosis and maintenance of vehicle faults. This technology has improved maintenance efficiency to a certain extent and reduced the time and labor costs of troubleshooting.

[0004] However, the existing technology still has many shortcomings: 1: Lack of maintenance guidance for vehicle users: The existing data collection system based on the OBD port is mainly for maintenance personnel, providing fault diagnosis and repair guidance, and lacks maintenance guidance for vehicle users. Vehicle users cannot obtain timely maintenance suggestions through the existing system, resulting in untimely vehicle maintenance, affecting the service life and performance of the vehicle.

[0005] 2: Lack of timely emergency response mechanism when a failure occurs: When a vehicle fails, existing technologies cannot guide drivers to quickly contact the corresponding vehicle repair station and rescue station in time. When facing vehicle failures, drivers lack effective guidance and support and cannot quickly find nearby repair or rescue service points, resulting in inefficient fault handling, increased vehicle downtime and driver distress.

[0006] 3. Lack of comprehensive vehicle maintenance management: The existing OBD data collection system mainly focuses on the collection and transmission of fault information, and lacks support for overall vehicle maintenance management. For example, it is impossible to automatically calculate and remind the vehicle's next maintenance time and mileage based on the vehicle's usage and historical data, resulting in unscientific and systematic vehicle maintenance management.

[0007] 4: Insufficient integration of maintenance and rescue resources: In the existing technology, the information integration between vehicle maintenance stations and rescue stations is not comprehensive enough, and there is a lack of effective classification and labeling systems. When drivers need maintenance or rescue, it is difficult to quickly and accurately find a suitable service point. This not only affects the efficiency of fault handling, but also reduces the satisfaction of vehicle users.

[0008] In summary, the existing OBD port-based data collection and maintenance guidance system has obvious deficiencies in guiding vehicle users to implement maintenance, emergency response when failures occur, and the integration of maintenance and rescue resources. These problems limit the comprehensiveness and efficiency of the system in practical applications, so it is necessary to make further improvements to it. Summary of the invention

[0009] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a vehicle fault monitoring and maintenance system with a simple structure and easy use, which comprehensively improves the capabilities of vehicle fault monitoring, maintenance guidance and fault emergency response by integrating data acquisition modules, data cloud platforms and offline repair and rescue networks.

[0010] The object of the present invention is achieved by the following method: A vehicle fault monitoring and maintenance system, comprising: a) a data acquisition module, installed at an on-board diagnostic system (OBD) port of a vehicle, the data acquisition module comprising a real-time data acquisition unit and a wireless transmission unit; b) a data cloud platform, connected to the data acquisition module via a wireless network, and used to receive the vehicle system data uploaded by the data acquisition module. The data cloud platform has a database that records the normal value range of various types of vehicles. When the data uploaded by the vehicle exceeds the normal value range, the data cloud platform sends a fault prompt to the owner and driver through a phone and a mobile application (APP), and guides them to log in to the data cloud platform to seek the best solution; c) An offline maintenance and rescue network integrates vehicle repair sites and rescue units across the country, and establishes characteristic tags of major maintenance parts for the repair sites and rescue units. The data cloud platform guides vehicle owners and drivers to quickly and accurately find nearby maintenance and rescue sites through the characteristic tags based on fault prompts, and provides accurate location navigation information.

[0011] Furthermore: the real-time data acquisition unit collects the vehicle's engine status, speed, fuel consumption, temperature, instrumentation, fault codes and other operating parameters, and uploads the multiple operating parameters to the data cloud platform in real time through the wireless transmission unit.

[0012] Furthermore: the data cloud platform can monitor and analyze the vehicle operation data of various types of vehicles in real time through the data analysis module, and automatically generate corresponding fault prompts when data anomalies are detected.

[0013] Furthermore: the data cloud platform integrates vehicle maintenance points, rescue stations and fault solutions in various places, and can recommend the best maintenance point, maintenance plan and rescue plan according to the fault type and geographical location.

[0014] Furthermore: the maintenance points and rescue units in the offline maintenance and rescue network identify the vehicle types and system components they mainly repair or rescue through preset special tags. The special tags include but are not limited to mainly repairing large trucks, fuel private cars, electric private cars, mainly replacing tires or repairing air-conditioning systems, etc. The data cloud platform matches the special tags with the fault prompts and recommends the most suitable maintenance and rescue sites.

[0015] Furthermore: the data cloud platform has the function of recording vehicle repair and maintenance data, and can calculate the next maintenance time and mileage of the vehicle based on historical data, and send maintenance reminders to vehicle owners and drivers.

[0016] Furthermore: the data cloud platform sends fault prompts and maintenance suggestions to car owners and drivers through mobile phone applications and telephone calls.

[0017] Furthermore: the wireless transmission unit is selected from 3G signal, 4G signal, 5G signal or WIFI signal communication technology.

[0018] Furthermore: the communication between the data acquisition module and the data cloud platform adopts encrypted transmission technology.

[0019] Furthermore: the data cloud platform includes a user interface module, which provides a graphical interface to display the vehicle operating status, fault information and recommended repair and rescue solutions.

[0020] The beneficial effects of the present invention are: 1. Simple structure, low production cost and improved market competitiveness.

[0021] 2. The data acquisition module in this system is permanently installed on the OBD port of the vehicle, and can collect multiple data including engine status, vehicle speed, fuel consumption, temperature, instrument information, fault codes and other operating parameters in real time. Through the wireless transmission unit (supporting 3G, 4G, 5G and WIFI communication technology), these real-time data are quickly uploaded to the data cloud platform to ensure the timeliness and accuracy of the data.

[0022] 3. The data cloud platform has a database that records and analyzes the normal operating range of various types of vehicles, and can accurately identify data anomalies. When vehicle data exceeds the normal range, the system automatically generates a fault prompt and sends reminders to the owner and driver via phone and mobile application (APP). In addition, based on the vehicle's historical operation and maintenance data, the system intelligently calculates and prompts the time and mileage of the next maintenance, provides a scientific and systematic maintenance plan, and helps car owners arrange vehicle maintenance reasonably and extend the service life of the vehicle.

[0023] 4. The system integrates vehicle repair sites and rescue units across the country, and establishes characteristic labels for them, identifying the types of vehicles and system components they mainly repair or rescue (such as mainly repairing large trucks, fuel-powered private cars, electric private cars, mainly replacing tires or repairing air-conditioning systems, etc.). When a vehicle breaks down, the data cloud platform guides the owner and driver to quickly and accurately find nearby repair and rescue sites through the data cloud platform based on the fault prompts and characteristic labels, and provides accurate location navigation information to ensure that the faulty vehicle can be handled in a timely and efficient manner.

[0024] 5. This system not only provides targeted maintenance guidance for maintenance personnel, but also provides timely maintenance suggestions for vehicle users, solving many problems of users in vehicle maintenance and troubleshooting. Through encryption transmission technology, the security and privacy of data during transmission are ensured, which improves the reliability of the system and the trust of users.
