Vehicle diagnosis system and method based on internet C/S mode

Abstract

The invention relates to vehicle diagnosis system and method based on an internet C / S mode. The method comprises the steps of: 1, establishing a connection between a terminal user and a server; 2, carrying out authentication on the terminal user and the server; 3, determining a vehicle type by the terminal user, sending the vehicle type information to the server to obtain a corresponding vehicle diagnosis program; 4, operating the diagnosis program, carrying out function diagnosis on the vehicle; 5, sending information to the server to obtain core library data required by the corresponding function; 6, computing the obtained core library data and displaying a result; and 7, judging whether ending the operation or not, if not, executing the next function diagnosis. The system is a C / S forming mode based on a certain central center on internet as a core, and has simple construction and convenient use. The method is convenient for uniform maintenance for the diagnosis core data, so that the fault of the vehicle can be accurately judged by using newest diagnosis data at any time as long as the server is linked.

Description

technical field [0001] The invention relates to a vehicle diagnosis system and method, in particular to a vehicle diagnosis system and method based on the Internet C / S mode. Background technique [0002] Automobile is the most familiar and common means of transportation for people, and it plays a very important role in people's life. Although automobiles have different qualities and various forms, various faults will inevitably occur during their use, which need to be eliminated or repaired in time. With the development of society and the progress of science and technology, more and more electronic technology, automation technology and computer technology are used in the design and production of automobiles. On the one hand, the degree of automation of automobiles is getting higher and higher, and the performance is better Superior, more convenient and flexible operation, on the other hand, it also puts forward higher requirements for vehicle maintenance and testing. The tr...

Problems solved by technology

[0004] Due to the continuous emergence of new types of automotive electronic controls, all kinds of automotive diagnostic equipment have a common shortcoming: they need to continuously upgrade the software in their own equipment, and the upgrading methods are different. Some of them are downloaded from the website. Upgrades, some through CD upgrades, etc., bring a lot of inconvenience and timelessness

In addition, since the current devices are independent, all data is stored in the device, so data is often cracked and copied, causing many unsafe hidden dangers
