Problems solved by technology
[0003] In order to solve the above problems, the present invention proposes an intelligent temperature-controlled fan device based on a single-chip microcomputer to solve the problem that the existing intelligent fan 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 speed of the fan. It is thought that the problem that the motor temperature is too high cannot be protected

The invention discloses an intelligent temperature-controlled fan device based on a single-chip microcomputer, 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 measuring module; wherein: the temperature sensor module, real-time acquisition The air temperature is transmitted 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 , to display 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 that can control the power on and off of the fan according to the distance between the person and the device. The motor speed is controlled to achieve the purpose of protecting the motor.
Description
technical field [0001] The invention relates to the field of fan rotation speed adjustment, in particular to an intelligent temperature-controlled fan device based on a single-chip microcomputer. Background technique [0002] At present, ultrasonic ranging sensors are not widely used in precise environmental detection. The reason is that ultrasonic waves are prone to refraction and reflection, strong mutual interference, and large noise. However, compared with other accurate ranging sensors, ultrasonic ranging sensors also have many advantages, such as low cost, non-planar detection range, and accurate ranging. How to effectively utilize these advantages of the ultrasonic ranging sensor and effectively shield the shortcomings of the ultrasonic ranging sensor is an inevitable problem in the application of the ultrasonic ranging sensor. Contents of the invention [0003] In order to solve the above problems, the present invention proposes an intelligent temperature-controll...
