Embodiment Construction

[0017] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.

[0018] A kind of automobile fault diagnosis method based on maintenance data and expert system, it comprises the following steps:

[0019] (1) Build an Internet-based automobile maintenance data database. The storage, operation, modification and upgrade of the database data are all placed on the network server. At the same time, the organization and retrieval of the database are based on the manufacturer, model, year and engine model Four-layer sequential structure to design;

[0020] (2), create an expert system simultaneously on this network server, expert system comprises reasoning machine, knowledge base and explaining mechanism;

[0021] (3) Initialization stage, that is, the data synchronization stage of the vehicle diagnostic instrument and the maintenance data database: connect...

Abstract

The invention discloses a maintenance information and expert system-based automobile failure diagnosis method, which comprises the following steps of: (1) establishing an internet-based automobile maintenance information database; (2) simultaneously establishing an expert system on a network server; (3) performing an initialization stage, i.e., performing a data synchronization stage of an automobile failure diagnostic apparatus and the maintenance information database; (4) performing a data fusion display stage; and (5) performing an intelligent failure judgment stage. The maintenance information and expert system-based automobile failure diagnosis method has the beneficial effects that maintenance information data is synchronously displayed when an automobile is tested by using the automobile failure diagnostic apparatus, so that query of the maintenance information data is facilitated, meanwhile, effects such as a dynamic data list and a dynamic circuit diagram can be realized through data fusion, and the user experience is enhanced; and in addition, judgment of experiment level can be provided during automobile failure diagnosis, so that the working efficiency and the precision of automobile diagnosis are improved.

Description

technical field [0001] The invention relates to an automobile fault diagnosis method based on maintenance data and an expert system, and belongs to the technical field of automobile service. Background technique [0002] At present, a car fault diagnosis instrument is just a computer with car diagnostic software. When the vehicle fault diagnosis instrument is connected with the diagnostic socket on the vehicle, the operation data of the vehicle electronic control system can be read through the vehicle fault diagnosis instrument. The number of electronic control systems on a car varies according to the configuration, generally including engine electronic control system, automatic transmission system, airbag system, brake anti-lock braking system, air conditioning system, etc. No matter how many electronic control systems a car has, they all communicate with external devices through the diagnostic socket on the car. The car fault diagnosis instrument is such a device that can...
