With people’s growing awareness of environmental protection, Motor vehicle exhaustemission has been more and more strict restriction. At the same time, rising gas prices, but alsomakes the motor oil costs more and more. In order to control vehicle exhaust emissions and fuelconsumption, the motorcycle refit, which has an electronic engine control unit (ECU), is thefuture development of a trend. However, ECU initialization, detection, debugging are in need ofhigh professional quality, the vast majority of the owners is does not have such a quality. And therapid development of the network, so that the distance is very far two people, can be real-timecommunication and communication. So, through the Internet, by professionals in the remotevehicle debugging, testing, to help users and repair site search vehicle fault, guide them to repair,is a very good solution.This article, aiming at the characteristics of ECU FAI EFI system, combined with thecurrent popular modular programming technology, studies how to realize various systemparameters from the in-vehicle ECU delivered to a local computer, according to the coding rulesof parameter analysis, find out the problem; when the complex problems, and how to transferfrom the local computer via the Internet to remote technical staff on the computer, constructedthe system framework and implementation scheme. In addition, we also construct a record ofvehicle fault and the user information databaseFAI remote diagnosis system has four main components. The first is the client softwaresystem, responsible for ECU recording parameters, through the serial port to connect line, inputto the local computer, it has simple fault detection and the effects of Socket; second is the centerterminal software, responsible for the acceptance of the client’s request, assignment(ServerSocket) and basic problem; third is the customer service end (end portion receivingcenter, expert) end distribution to customers, communicate with the vehicle, on variousparameters real-time monitoring, debugging, to help users find a fault, guide users to repair; fourth part for the database, in addition to a vehicle data, the database also stores customerinformation, including the customer’s basic information, vehicle purchase time, fault recordingand recent repair station. In order to provide customers with information services at the sametime, help enterprises to previous sales tracking survey, analysis of market changes. The entiresystem through the Internet network connection.Using the system, the customer can be local and remote two ways to solve the fault. For thecommon problem, system of built-in fault, eliminating the customer technical manual time; forsome common, difficult to solve the problem, a system to provide remote expert diagnosis, helpcustomers solve the problem.In the process of system development, borrowed from a number of excellent softwaredevelopment experience, the development platform for the Windowxp Home edition, eclipseintegrated development platform, the Java language, database using MySQL database. Thesystem of packing process, using exe4j technology.FAI remote diagnosis system is greatly convenient for the vehicle fault repair, can not onlymeet the domestic needs of the market in China, but also for sales in foreign vehicle repair guide.To achieve a truly global sales, service all over the world the ideal. On vehicle sales andtechnical extension has significant meaning. |
