Standard diagnosis method based on professional diagnosis

Abstract

The invention provides a standard diagnosis method based on professional diagnosis. The standard diagnosis method comprises the following steps of 1, providing a diagnosis connector, wherein the diagnosis connector comprises a diagnosis interface module, a first microprocessor module, a first storage module and a standard data communication interface module, and the first storage module is used for previously storing a standard data flow general base; 2, providing a vehicle, connecting the diagnosis connector with the vehicle, scanning all electrically controlled systems of the vehicle, obtaining all data flow items, comparing all data flow items with the standard data flow general base, and recording the data flow items simultaneously existing to form a vehicle special database; 3, providing a client end, and establishing the communication connection between the diagnosis connector and the client end; 4, controlling the diagnosis connector to diagnose the data flow and the like in real time through the standard data communication interface in accordance with the standard format according to the requirements of a user, and sending the information to the client end. The standard diagnosis method has the advantages that the development period of the client end can be shortened, the production cost is reduced, and the operation steps of the user are simplified.

Description

technical field [0001] The invention relates to the field of automobile fault diagnosis, in particular to a diagnostic method for diagnosing the electronic system inside the automobile through a special diagnostic joint and outputting data in a standard data format. Background technique [0002] With the rapid development of China's auto industry and the continuous popularization of family cars, the huge market potential of life after cars has attracted widespread attention from all parties. After years of market development and popularization, the automotive fault diagnosis system has been effectively developed. [0003] However, due to traditional market factors, multi-system and multi-functional professional diagnostic equipment is bulky and expensive. The customer group is traditional auto repair shops, while DIY equipment for individual customers is small, low in price, easy to operate and Based on the versatility of OBDII / EOBD system diagnosis and other advantages, it...

Problems solved by technology

[0003] However, due to traditional market factors, multi-system and multi-functional professional diagnostic equipment is bulky and expensive. The customer group is traditional auto repair shops, while DIY equipment for individual customers is small, low in price, easy to operate and Based on the versatility of OBDII / EOBD system diagnosis and other advantages, it has gradually entered the personal user market of family cars

But at the same time, because the traditional DIY equipment is based on OBDII / EOBD, it can only diagnose the power system related to emissions, and its functions are simple, so it cannot make a comprehensive diagnosis of the vehicle, which limits its further development potential

And professional diagnostic equipment has also set up a solid barrier for entering the personal market due to its high price.

At the same time, a large number of technical terms used by these diagnostic equipment have also formed a technical barrier, and ordinary end users do not know how to use the diagnostic equipment

The miniaturized devices of professional diagnostic equipment are also the same as professional equipment, a large number of professional technical terms and differentiated data streams, and complex operations set up great obstacles for individual customers to use
