Problems solved by technology

Therefore, software developers must wait for the completion of the UPS hardware design before software debugging, thus delaying the development and debugging progress of the UPS control software and the entire system
[0005] (2) When debugging in the initial stage of UPS control software development, it is difficult to ensure the correctness of the control software because the software has just been written
The UPS control unit plays a key role in the whole machine. Once the software timing is inaccurate or the logic error occurs, it is easy to cause damage to the whole UPS components or even cause the danger of explosion.
[0006] (3) Since the UPS machine is often working
