Method and device for vehicle failure real-time group diagnosis

Abstract

The invention provides a method and a device for vehicle failure real-time group diagnosis. A to-be-tested vehicle device, a diagnosis data analyzing device and a control device are electrically connected and matched, the control device which is provided with a transit server is added between a failure diagnosis device and the to-be-tested vehicle device, so that a plurality of computers can diagnose the real-time fault code and the data flow of the same to-be-tested vehicle device at the same time, and real network diagnosis function is achieved. The method and the device for vehicle failure real-time group diagnosis can be combined with an existing multi-media classroom of a school, and the fact that a server and a client side diagnose different signal sources of the to-be-tested vehicle device at the same time is achieved. A plurality of vehicle failure diagnostic units do not need to be bought, teaching cost is lowered, the number of students who can participate in diagnosis at the same time is increased, the real network diagnosis function is achieved, the students can carry out diagnosis operation at the same time and clearly and visually see the results of diagnosis and each data flow parameter, and understanding speed of the students and teaching efficiency can be improved in limited teaching time.

Description

technical field [0001] The invention relates to a method and device for automobile teaching and training, in particular to a method and device for real-time group diagnosis of automobile faults. Background technique [0002] In the teaching of modern automobile maintenance majors and the practical training of automobile troubleshooting, the diagnostic equipment used to determine automobile faults plays a vital role. Especially with the development of automobile electronics, electronic integration technology has been widely used in automobiles. This requires automobile maintenance personnel to have electronic maintenance skills and knowledge, which also has new requirements for teaching and training in the field of automobile maintenance. In order to more fully meet the teaching requirements, teaching institutions have to purchase a large number of automotive electronic equipment, testing equipment Tools and products to meet the needs of students. [0003] Car fault diagnos...

AI Technical Summary

Problems solved by technology

[0007] 1. The cost of automobile fault diagnosis instrument is expensive, especially in today's era of continuous advancement of technology and frequent updating of automobile products and supporting products. If each student is allowed to hold a diagnostic instrument, it will seriously increase the teaching institutions. teaching cost

If increasing the number of automotive fault diagnosis instruments to meet the practical needs of each student, the cost is too high;

[0008] 2. Due to the small area of ​​the display and operation panel of the automobile fault diagnosis instrument, the teacher cannot take care of all the students at one time during the training process. In the limited course time, only a few students can practice the operation by hand, which leads The number of students in each class is limited, which reduces the teaching efficiency;

[0009] 3. There can only be one-to-many demonstrations. In the limited time of the training course, it is impossible for each student to carry out actual operation on the fault diagnosis instrument, and it is impossible to exercise the hands-on ability and reduce the understanding level of the students.
