AI Technical Summary

Problems solved by technology

In the field of intelligent control teaching, the constant pressure water supply system has increasingly become an important research topic. However, the actual application of the variable frequency constant pressure water supply system has a large structure, wide distribution, high price, and is not visually intuitive. It is not suitable for direct use as a teaching experiment device.
