A kind of vehicle fault diagnosis system containing In-vehicle networking system

Technical field

The utility model relates to automobile failure diagnosis field, is specifically related to a kind of vehicle fault diagnosis system containing In-vehicle networking system.

Background technology

Current domestic development of vocational education, particularly vocational education are big after the meeting, and professional colleges is increased input by country, professional colleges student can rise this, even pursue the master degree and pursue the Ph.D after, vocational education has welcome good growth momentum. But traditional vocational education pattern can not meet the development of modern job education, particularly automobile failure diagnosis this respect, conventional education is inculcated based on theory, is operating as auxiliary, because not adapting to the development need in epoch a bit, being badly in need of will real training teaching platform based on internet.

Summary of the invention

In view of above content, a kind of vehicle fault diagnosis system containing In-vehicle networking system that the utility model provides, is calculated as basis with internet cloud, the interactive model of exploitation automobile failure diagnosis. The utility model discloses a kind of vehicle fault diagnosis system containing In-vehicle networking system, comprise main frame, subsidiary engine, trouble diagnosis car. Main frame is provided with the real training software of vehicle fault diagnosis system, according to automobile failure diagnosis flow process, it is possible to simulation arranges fault, reads and appraises student performance; Main frame can be demonstrated the munipulation, and comprises ignition switch operations, connection diagnostic instrments, reading fault code, reading data flow, the online signal of detection (voltage, waveform), components and parts inspection, circuit measuring, trouble spot confirmation and failture evacuation. Student carries out failed operation on subsidiary engine, according to the fault of design, operates according to diagnostor. This automobile failure diagnosis model can to the real car trouble diagnosis of automobile, and experience system can simply, directly with real car and existing automotive practical-training stand be connected, and system can realize the fault real trainings such as the accurate remote control of real car and stand.

The utility model achieves the above object by the following technical programs: a kind of vehicle fault diagnosis system containing In-vehicle networking system, is made up of main frame, trouble diagnosis car, subsidiary engine, malfunction coefficient device, printer and simulating signal setter.

Described trouble diagnosis car first coupling end is connected with main frame by wire, and trouble diagnosis car the 2nd coupling end is connected with simulating signal setter one end by wire, and the simulating signal setter the other end is connected with subsidiary engine by wire; Malfunction coefficient device is connected with main frame, trouble diagnosis car, simulating signal setter respectively by wire simultaneously, and printer is connected with main frame, trouble diagnosis car, simulating signal setter respectively by wire simultaneously.

Described main frame can pass through the real training software of system, according to automobile failure diagnosis flow process, it is possible to simulation arranges fault, reads and appraises student performance; Described main frame can comprise ignition switch operations, connection diagnostic instrments, reading fault code, reading data flow, detection on-Line Voltage and waveform signal, components and parts inspection, circuit measuring, trouble spot by real training software simulating and confirm and failture evacuation.

Described subsidiary engine according to the fault of teacher's design, can operate according to diagnostor, and student only need to log in client terminal software, just can carry out trouble diagnosis real training simultaneously, and real training record can preserve, and assesses foundation as teacher. Teacher can follow the tracks of the whole process of student's real training.

Described malfunction coefficient device can show the vehicle failure that main frame is arranged, and feeds back to trouble diagnosis car simultaneously, it is achieved the signal detected on software interface in real time is synchronous in real time with real car.

Outstanding advantage of the present utility model is:

1, the utility model platform character is practical, and structure is simple, rational in infrastructure, low cost of manufacture;

2, operating light flexibly, ornamental and workable, has to understand in student;

3, the trouble signal that main frame is arranged is synchronous with real car.

Accompanying drawing explanation

Fig. 1 is a kind of vehicle fault diagnosis system structural representation containing In-vehicle networking system of the present utility model.

Embodiment

Below in conjunction with drawings and Examples, the technical solution of the utility model is described further.

Comparison Fig. 1, in a better embodiment of the present utility model, a kind of vehicle fault diagnosis system containing In-vehicle networking system, is made up of main frame 1, trouble diagnosis car 2, subsidiary engine 3, malfunction coefficient device 4, printer 5 and simulating signal setter 6.

Described trouble diagnosis car 2 first coupling ends are connected with main frame 1 by wire, and trouble diagnosis car 2 the 2nd coupling end is connected with simulating signal setter 6 one end by wire, and simulating signal setter 6 the other end is connected with subsidiary engine 3 by wire; Malfunction coefficient device 4 is connected with main frame 1, trouble diagnosis car 4, simulating signal setter 6 respectively by wire simultaneously, and printer is connected with main frame 1, trouble diagnosis car 4, simulating signal setter 6 respectively by wire simultaneously.

Described main frame 1 can pass through the real training software of system, according to automobile failure diagnosis flow process, it is possible to simulation arranges fault, reads and appraises student performance; Described main frame can comprise ignition switch operations, connection diagnostic instrments, reading fault code, reading data flow, detection on-Line Voltage and waveform signal, components and parts inspection, circuit measuring, trouble spot by real training software simulating and confirm and failture evacuation.

Described subsidiary engine 3 according to the fault of teacher's design, can operate according to diagnostor, and student only need to log in client terminal software, just can carry out trouble diagnosis real training simultaneously, and real training record can preserve, and assesses foundation as teacher. Teacher can follow the tracks of the whole process of student's real training.

Described malfunction coefficient device 4 can show the vehicle failure that main frame is arranged, and feeds back to trouble diagnosis car simultaneously, it is achieved the signal detected on software interface in real time is synchronous in real time with real car.

Described printer 5 can receive the printing signal of main frame 1, subsidiary engine 3 and malfunction coefficient device 4.

Above-mentioned explanation is the detailed explanation for the better possible embodiments of the utility model, but embodiment also is not used to limit patent application scope of the present utility model, the equal change or the modification that complete under technical spirit suggested by all the utility model are changed, and all should belong to the utility model and be contained patent scope.
