Embodiment Construction
[0012] The intelligent recording function of the automotive computer diagnostic instrument is to automatically record the key information of the entire system running track, such as communication interaction data, interface information, etc. It is the interactive data of the communication link layer, the click message of the human-computer interaction interface of the application layer and the identification of abnormal conditions. The purpose is to minimize the index information data records, and to reproduce the entire process of historical testing in the system supporting our product software without hardware separation. Generally speaking, this function is like a camera, which can record the whole process of the test, and when the recorded process needs to be played, the diagnostic product itself becomes a player, which can be opened by the display software of the car diagnostic instrument and played. content.

A diagnostic apparatus with an intelligent recording function abstractly comprises three structural layers, namely, a physical layer composed of hardware modules connected with an automotive electronics control unit communication interface, a data link layer composed of data processing modules, and an application layer composed of a display module for displaying a man-machine interaction interface and a protocol analyses module. According to the three structural layers, the physical layer is in data interactive linkage with the data link layer, and the data link layer is in interactive linkage with the application layer, so as to form an information interaction chain between an automobile and an operator; a recording cache is arranged in the diagnostic apparatus and is in information interactive linkage with the data link layer and the application layer. With little recorded data amount, communication during the remote diagnosis process is less affected; hardware test process and result can be played back without the aid of the hardware; a teaching platform through which real cases can be shared and discussed is built; the functions of the diagnostic apparatus can be unceasingly improved and upgraded through unceasingly collecting and enriching real diagnose data resources; the product quality and reliability can be unceasingly improved through updating the software.
Description
【Technical field】 [0001] The invention relates to the field of automotive electronics, in particular to an automotive electronic diagnostic system, in particular to a diagnostic instrument with intelligent records for recording, sharing, and archiving of automotive diagnostic technologies. 【Background technique】 [0002] In 2009, my country's automobile production and sales exceeded 10 million for the first time, ranking third in the world. The vigorous development of the automobile industry has driven the development of a series of related industries.
