The invention discloses an intelligent control system based on a second-order filter circuit for a fan. The intelligent control system is characterized by being mainly composed of a control chip U2, a diode rectifier U1, a field-effect transistor MOS, a polar capacitor C9, a polar capacitor C10, a diode D6, a diode D8, a resistor R6, a temperature measurement control circuit connected with a pin TRIG, a pin THRE and a pin CONT of the control chip U2 respectively, the second-order filter circuit serially connected between a temperature sensor WD and the temperature measurement control circuit, a switch drive circuit serially connected between the diode rectifier U1 and the control chip U2, and the like. The intelligent control system disclosed by the invention is capable of controlling the turn-on and turn-off of the fan through detection information for an environment temperature, and further capable of adjusting a wind power of the fan through the changes of the environment temperature, thus guaranteeing intelligent control of the intelligent control system for the fan.
Description
technical field [0001] The invention relates to the electronic field, in particular to an intelligent control system for a fan based on a second-order filter circuit. Background technique [0002] Fans are favored by people because they can bring cool breeze to people in hot summer. With the continuous development of science and technology, in order to meet the different needs of people, the fan control system is also constantly innovating, that is, the fan control system has developed from the original button shifting wind control system to a remote control wind control system All these control systems require people to adjust the wind power of the fan or turn it on and off, which cannot meet people's requirements for intelligent electronic products. [0003] Therefore, it is urgent to provide a fan control system that can not only automatically adjust the wind power of the fan, but also automatically control the opening and closing of the fan.
