[0118] Next, through Figure 4 The data transmission diagram of FIG. 1 illustrates the data transmission of the application (or software) corresponding to each system. Figure 4 The solid arrows represent data transmission, and the dotted arrows represent instruction transmission.

[0119] In addition, Figure 4 The video recording software does not interact with the data bus, the test data analysis software does not interact with the data bus, and the trailer control application does not interact with the data bus. This is another implementation method of the present application and is only used as an example, but will not affect the implementation of the present application.

This saves labor costs, improves user experience, achieves the goal of reducing costs and increasing efficiency, and improves test efficiency overall.

[0121] Finally, it should be noted that the above is only the preferred implementation of the present application, and the present application is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present application should be considered to be included in the scope of protection of the present application.
