With the rapid development of economy and society,human beings have put forward higher requirements for envi-ronment and quality of life.As an important link to improve the sanitation environment and improve the quality of life,smart toilets also keep up with social needs in manufacturing reform and innovation.However,in recent years,research on the development of smart toilets has mostly focused on software programs such as artificial intelligence health detection.The research process has carried out a detailed theoretical analysis for the introduction of artificial intelligence programs into smart toilets,but its specific implementation methods,such as key manufacturing technologies such as control circuit hard-ware integration that affect the development and use of existing smart toilets,have not been mentioned too much.The re-search and development of artificial intelligence system of intelligent toilet is inseparable from the support of the basic con-trol circuit hardware.Through in-depth research and experiment on the hardware manufacturing of the internal circuit of intelligent toilet,the author proposes to optimize the cable connection circuit of the internal module of intelligent toilet,and realize the design and development of integrated circuit board of functional modules.In order to meet the application needs of modern intelligent toilet in the health function expansion of artificial intelligence system.
