Vehicle information remote monitoring and fault diagnosis system

Abstract

The invention discloses a vehicle information remote monitoring and fault diagnosis system. The system comprises an intelligent vehicle-mounted terminal which is installed on a vehicle and is used foracquiring vehicle fault information and real-time state information, a cloud server platform and an intelligent mobile terminal. The system is used for instantly analyzing and processing a vehicle fault, and graphically displaying the various kinds of data of a vehicle on the intelligent mobile terminal. The invention also provides a vehicle remote diagnosis method. When the vehicle has a fault,the vehicle-mounted terminal can automatically transmit a fault code to cloud, a cloud management platform analyzes the fault code and matches a corresponding solution scheme to the user vehicle-mounted terminal, nearby selectable repair manufacturers are pushed to a user via GPS, and the user can check the real-time operation state information of the vehicle through the intelligent mobile terminal APP. Through the intelligent mobile terminal, a driving habit and vehicle fault hidden troubles are checked. A driver can correct a bad driving habit through the mobile terminal and potential safetyhazards of the vehicle are reduced.

Description

technical field [0001] The invention relates to a vehicle information remote monitoring and fault diagnosis system, in particular to the technical fields of remote information collection, fault diagnosis and Internet of Vehicles of automobiles. Background technique [0002] In daily life, cars have become an essential tool for people to travel. However, while passenger cars bring convenience to people, driving safety issues have gradually become prominent. Among them, car failures and hidden safety hazards are one of the major threats to personal safety. Personal safety and property damage accidents due to automobile failures account for a considerable proportion of automobile-related accidents every year. Although the vehicle safety parameters formulated by relevant state departments are becoming more and more rigorous, the safety technology level of automobiles The traffic police and other safety law enforcement departments are increasingly strict in control, but safety li...

Problems solved by technology

The OBD terminal is connected to the internal bus of the car to collect the internal information of the vehicle and send it to the cloud server, and then through the cloud server diagnosis and classification, the diagnosis script is sent to the vehicle terminal. This system has initially achieved the effect of vehicle remote diagnosis, but it can only be used in Effective diagnosis after a fault occurs cannot provide fault warning and prediction functions; and the system lacks a GPS module. When users face a fault that cannot be handled by themselves, they cannot provide the address of the repair manufacturer near the current location, which lacks emergency practicability; The vehicle-mounted terminal can only read limited data, and the space in the vehicle is limited, so it is difficult for users to view vehicle status information in real time; in addition, the invention does not clearly define the frame structure of each important information interaction step, and the frequent information between the vehicle-mounted terminal and the cloud server Interaction is prone to garbled codes and errors, without specificity, effectiveness, and practicability
