The data in real time data and the data storage cell are stated, data analysis are carried out, to obtain diagnostic result.
Further, the diagnosis server further includes diagnosis resolution unit, for carrying out diagnosis parsing to diagnostic result,
Parsing result is diagnosed to obtain；For showing in the client, the diagnosis parsing result saves the diagnosis parsing result
In the data storage cell.
Data analysis unit 1004 carries out the analysis of data, sufficiently carries out data analysis to historical data and real time data,
Including the operation such as logic analysis and/or data calculating, diagnostic result is obtained, the analysis of these data, which can be, utilizes trained mould
Type carries out, and is requested according to different diagnosis, can be analyzed using different models, these models are also possible to adaptively learn
The model of habit.Obtained diagnostic result is sent to client by data transmission unit 1002, can also mention what diagnosis terminated
Show and is sent to client and shows on the client.
In actual application, the diagnostic result exported after analysis can be diagnostic code, that is, the corresponding volume of failure
Code.For the readability to failure analysis result of enhancement-client, diagnosis resolution unit can be set in client, be used for root
Diagnosis parsing is carried out according to diagnostic code, to obtain diagnosis parsing result, client shows diagnosis parsing result, such as diagnosis knot
Fruit is 001,001 to represent relay failure, which is sent to client, and diagnosis resolution unit parses this
Failure is relay failure, then shows " relay failure " in client, in this way, being recognized that this is specific from client
Defect content.Meanwhile client also sends the diagnostic result and corresponding diagnosis parsing result on diagnosis server, with
Data preservation is carried out for diagnosis server, the data of preservation enter in historical data, can also as the data basis of follow-up diagnosis
Using the study and training as analysis model.
In addition, can all be encryption data, Ke Yili for the data transmitted between above-mentioned client and diagnosis server
Solution, for the data of encryption, needs to complete when in use to decrypt accordingly, the mode of encryption includes but is not limited to that DES adds
Close/decryption, MD5 or CRC32 verification etc..
The vehicle diagnosing system of the embodiment of the present invention is described above, within the system, passes through vehicle history number
It is analyzed according to real time data, obtains diagnostic result, maintenance side so only needs to operate client, without relying on various diagnosis
