Stepless adjustment system and method of intelligent closestool rotary knob

The invention discloses a stepless adjustment system and method of an intelligent closestool rotary knob. The stepless adjustment system comprises a rotary knob assembly and a main control module; therotary knob assembly generates a voltage signal in the rotating operation, the main control module judges the rotation angle of the rotary knob assembly according to the voltage signal, the adjustingvariable is calculated according to the rotation angle, and finally the controlled plant is adjusted to the corresponding amplitude or position according to the adjustment variable. The stepless adjustment system is not only more convenient to operate and more accurate to control, but also can achieve stepless adjustment, is particularly applicable to refine adjustment of the water temperature, wind temperature, seat temperature, water pressure and spraying rod position of the intelligent closestool, and provides a user with better experience. 本发明公开了一种智能马桶旋钮的无级调节系统及方法，其包括旋钮组件和主控模块；所述旋钮组件在旋转操作时产生电压信号，所述主控模块根据所述电压信号判断所述
