4. Characteristics of testing system software
The testing system software is developed according to software engineering requirements, striving to achieve powerful functionality, stability, and reliability.

At the same time, the software is expanded to have expert system functionality.

4.1 Human Computer Interaction Interface

The interface is the manifestation of the testing system and the window for users to analyze and judge. Users can set self check and test items, as well as

perform printing and fault diagnosis. Set the project to be tested in the human-computer interaction interface, and the computer sends speed commands to the tested driver.

The data obtained through a dedicated interface and other

testing equipment is analyzed and compared online by the testing software to provide a conclusion on whether it is qualified or not. At the same time, the expert diagnostic

knowledge base is called to diagnose the fault and provide a solution to the fault. The composition of the human-computer interaction interface module is shown in Figure 5.

4.2 Testing System Dynamic Link Library

The dynamic link library of the testing system adopts the standard access method ODBC (Open Database Connectivity), and establishes a set of dynamic link library DLLs,

namely the driver basic information database and the specialized machine diagnostic knowledge database. The main content of the basic information database of the drive is

the technical parameters of the drive, and the expert diagnostic knowledge database mainly analyzes typical faults of the drive. If users need to expand the content of the expert

diagnostic knowledge database, they can add it through the human-machine interface.
