Intelligent temperature-control fan based on ultrasonic distance measurement

Abstract

The invention discloses an intelligent temperature-controlled fan based on ultrasonic distance measurement, which includes a temperature sensor module, a button module, a minimum system module of a single chip microcomputer, a motor drive circuit module, a display module and an ultrasonic distance measurement module; wherein: the temperature sensor module, real-time The collected air temperature is sent to the minimum system module of the single-chip microcomputer for processing; the motor drive circuit module is connected to the minimum system module of the single-chip microcomputer, and the minimum system module of the single-chip microcomputer controls the fan motor circuit module, and then controls the motor drive circuit module to drive the motor to work; the display module is connected to the minimum system module of the single-chip microcomputer The module displays the measured temperature and the set temperature range. Aiming at the characteristics of wide angle, easy reflection and strong interference of the ultrasonic distance measuring sensor, the present invention provides a smart fan, which can not only control the on / off of the fan according to the distance between the person and the device, but also control the speed of the fan.

Description

technical field [0001] The invention relates to the field of fan rotation speed adjustment, in particular to an intelligent temperature-controlled fan based on ultrasonic distance measurement. Background technique [0002] The most prominent disadvantage of the traditional electric fan is that it cannot adjust the wind power in a timely manner according to the temperature change. When the temperature cools down in the early morning, the electric fan is still working, but people cannot notice it because they are asleep, which wastes power resources and easily causes colds. And it cannot be guaranteed whether people can feel the wind force of the fan. When the weather is hot, the fan continues to operate and the motor continues to be in a high temperature state, which will reduce the life of the motor. [0003] In response to the above problems, although there are some fans that can automatically control the temperature, most of them discard the traditional manual mode. There ...

Problems solved by technology

[0004] In order to solve the above problems, the present invention proposes a fan adjustment device based on ultrasonic distance measurement to solve the problem that the existing smart fans can only use the distance measured by ultrasonic waves to control the power on and off, but cannot use the distance measured by ultrasonic waves to control the fan speed.
