Check method for mass data of vehicle OBD (On Board Diagnostics) code reading card

Abstract

The invention provides a check method for mass data of a vehicle OBD (On Board Diagnostics)code reading card, comprising the following steps of, firstly, supplying an OBD-II code reading card which is provided with a communication interface; secondly, writing a data uploading test code in the OBD-II code reading card; thirdly, making a check tool in a computer, wherein the check tool is internally provided with an original text database; fourthly, electrically connecting the OBD-II code reading card with the computer through the communication interface, displaying text data information in theOBD-II code reading card, and simultaneously uploading the text data information to the computer; and fifthly, after receiving the text data information uploaded by the OBD-II code reading card by the computer, searching original data of the text data information in the original text database by the check tool, and comparing the found original data with the received text data information to automatically check the text data information. The invention can efficiently and accurately check mass text data information in the OBD code reading card, without increasing any material cost.

Description

technical field [0001] The invention relates to a method for verifying data on a code-reading card, in particular to a method for verifying a large amount of data in a hand-held device for an automobile OBD code-reading card. Background technique [0002] For better environmental protection performance and better handling performance, automobiles have entered the era of electronic control since the 1980s. With the extensive and in-depth application of microelectronics technology, automotive electronic control systems can not only monitor the real-time operation of various functional components of automobiles , state records, etc., and gradually have the function of interacting with data information such as these states and records through a dedicated interface. In 1994, the Society of Automotive Engineers (SAE) proposed the standard specification for the second-generation on-board self-diagnosis system (OBD-II), which includes software protocols, hardware interfaces, physica...

Problems solved by technology

After going through so many steps, how to ensure that every piece of data is the information we want to see? It is almost impossible to rely on testers to check one by one, time-consuming and labor-intensive and prone to omissions, and testers are unlikely to know more than a dozen languages, so testers usually only check part of the information in the prior art For verification, it is often that a large number of users accidentally find that some information is wrong during random use, and then feed it back to the manufacturer for modification and upgrade. It is difficult to guarantee the correctness of the entire massive data
