Description
Technical field
The present invention relates to the method for calibration of data on a kind of code reading card, relate in particular to a kind of automobile OBD code reading card handheld device is carried out verification to mass data method that is used for.
Background technology
Handling for more excellent environmental-protecting performance and Geng Jia; Automobile gets into the automatically controlled epoch from the eighties in last century; Along with microelectric technique application extensively and profoundly; Automobile electric control system not only can carry out real time execution monitoring, state recording etc. to each functional part of automobile, but also progressively possessed the interface of data messages such as these states and record through special use is carried out mutual function.1994 AIAE American institute of automobile engineers (SAE) standard criterion of the second generation with car self-diagnosable system (OBD-II) proposed, it has all made unified regulation at the software protocol of automobile self diagnosis, hardware interface, physical size, DTC, stream data definition etc. aspect many.As time goes on, the standard of OBD-II also development widely, simultaneously with regional EOBD (European Union), JOBD different versions such as (Japan) based on OBD-II appearred also at country variant.
The OBD code reading card is through the vehicle diagnosis interface data in the automobile ECU to be read, and the information of these data representatives carried represents to the user.Continuous development and perfection along with the OBD standard; Its related data content is more and more abundanter, data volume is also more and more huger; With DTC information is example; Among the OBD standard fault codes of defined just have thousands of, if add in the world the self-defined DTC of producer in each series automobiles of main automobile brand then can reach up to ten thousand, if consider country variant and the area multi-lingual problem of using again; Suppose and consider the main language of 10-20 kind, so just only DTC information just can reach ten thousand of 10-20.Correctness in automobile OBD code reading card, how to verify these data be one very important, be again very loaded down with trivial details thing simultaneously.Tens thousand of in the face of among the OBD to hundreds thousand of data messages; At first be the correctness that will guarantee raw data, yet urtext to be passed through text code arrangement, data conversion treatment, data usually and downloaded to a plurality of steps such as code reading card memory, data message inquiry, text data information demonstration and just finally on display screen, seen by the user.Pass through so many step; How to guarantee that each bar data all is that we hope the information seen? If lean on the tester to check it almost is impossible one by one; Take time and effort and very easily appearance careless omission; The tester also unlikely knows tens kinds of language, so the tester just spot-check partial information usually and verifies in the prior art, and in use at random, to chance on certain information wrong for a large number of users often; Feed back to manufacturer's upgrading of making amendment again, the correctness of whole mass data is difficult to be guaranteed.Therefore be necessary very much to provide a kind of efficiently, method is verified the correctness of mass data information accurately.
Summary of the invention
The objective of the invention is to; A kind of method of calibration that is used for automobile OBD code reading card mass data is provided; It increases simple test code in code reading card, cooperate PC work to operate, and can carry out efficiently text data information a large amount of in the OBD code reading card, verification accurately.
For realizing above-mentioned purpose, the present invention provides a kind of method of calibration that is used for automobile OBD code reading card mass data, comprises the steps:
After step 5, computer are received the text data information that the OBD-II code reading card uploads; The verification instrument is searched the raw data of text data message in the urtext database; And raw data that finds and the text data information received compared, automatically text data message is carried out verification.
Communication interface on the said OBD-II code reading card is USB interface or COM serial port.
The test code that writes in the said step 2 does not influence the operation logic of OBD-II code reading card Central Plains code.
In the said step 5; The verification instrument is searched the raw data of text data message in the urtext database; And the text data information that raw data that finds and the OBD-II code reading card received are uploaded compares, and wrong text entry is got off, and generation error is reported.
Beneficial effect of the present invention: the method for calibration that is used for automobile OBD code reading card mass data provided by the present invention; It adds simply and does not influence the test code of operation logic in code reading card; In PC, make a cover instruments of inspection software, be connected with PC through the interface on the code reading card, the operation test code is used for data presented with code reading card and is uploaded to computer verification tool software simultaneously; The verification tool software is searched corresponding information and is compared checking from the urtext database; Thereby realized the verification to the data correctness, it does not increase any Material Cost, and proof procedure need not manual intervention; Finally by PC verification instrument output verification result; Save a large amount of manpower test processs, and avoid testing the factor that the mass data human negligence makes mistakes, solved tens thousand of validation problems in the OBD code reading card effectively to hundreds thousand of data correctness.
In order further to understand characteristic of the present invention and technology contents, see also following about detailed description of the present invention and accompanying drawing, yet accompanying drawing only provide reference and the explanation usefulness, be not to be used for the present invention is limited.
Description of drawings
Below in conjunction with accompanying drawing, describe in detail through specific embodiments of the invention, will make technical scheme of the present invention and other beneficial effects obvious.
In the accompanying drawing,
Fig. 1 is the schematic flow sheet that is used for the method for calibration of automobile OBD code reading card mass data of the present invention;
Fig. 2 is the application principle synoptic diagram of the present invention's one specific embodiment.
Embodiment
Technological means and the effect thereof taked for further setting forth the present invention are described in detail below in conjunction with the preferred embodiments of the present invention and accompanying drawing thereof.
