AI Technical Summary

Problems solved by technology

During the training process, calculation, wiring, and manual voltage adjustment are required to change the pressure drop and load value training for many times. Therefore, this method has a low degree of automation and the possibility of human error. The training efficiency is low, which is not conducive to the training / assessment of trainees , it is difficult to achieve a better training effect
