AI Technical Summary

Problems solved by technology

Designers used to design hardware according to their own projects, and the designed hardware lacked versatility, resulting in a lot of waste of manpower, financial resources and energy

The modification of relevant parameters and settings must also be carried out in the program, so it is extremely inconvenient

There are disadvantages such as unfriendly man-machine interface, complicated and difficult control program writing
