Vehicle Fault Diagnosis And Fault Maintenance System Key Technology Research And Design

In order to satisfy the requirement of modern information technology war to thetransport equipment in the military transport, promote the development of digital,scientific and intelligent of the intelligence maintain of the transport equipment oftroops, we study the diagnosis and maintain of the transport equipment trouble of thevehicle of troops and comprehensive use the technology of computer and the diagnosisof troubles to research a system of the diagnosis and maintain of the troubles of vehicleswhich combine the signal diagnosis and the knowledge inferential diagnosis. Thecontents are as follows:1. We established the whole structure of the system of the diagnosis and maintainof the troubles of vehicles. By way of the analyze and limiting the function of system indetail, we structured two units about signal diagnosis and the technology of maintain.The system realized the functions which can diagnose the transport equipment ofvehicle and provide the information of maintain and so on. It also lays a foundation ofensuring information for the logistics maintain.2. On the base of overall analyzing the diagnosis tactics of the troubles of vehiclesand the diagnosis method of Support Vector Machine and Artificial Neural Networksand so on, we handle the technology of Support Vector Machine to tap the signaldiagnosis unit of the troubles of vehicles which is on the grounds of the technology ofSupport Vector Machine. Then, by way of resolving wavelet packet data signal andabstracting and optimizing, we realized the function of analytic diagnosis for the signalsof the troubles of vehicles.3. We studied and developed the maintain technology manual of vehicle which hasthe knowledge inferential function. The main contents include: according to the shapeof the form of the trouble information and maintain information of the vehicleequipment, we use binary file and database access，these two ways, to manage data andthen develop database of trouble information and maintain information; by way ofstudying the trouble information of vehicle, we designed the way about the knowledge inferential diagnosis of trouble. The manual provides a good stage for the concentratedand united charge of the data of the trouble of the vehicle of troops and maintain.4. From the practical angle, we study and develop the system of the diagnosis andmaintain of the troubles of vehicles which is about the common vehicles of militarytransport. The functions which was realized by the system include: the function oftrouble diagnosis; the function of checking the vague troubles; the function ofbrowsing、printing、and keeping the user’s diagnostic data; The function of maintain andenlarge the knowledge store.
