Problems solved by technology

The control method of this device belongs to dynamic air supply, but the dynamic air generated is quite different from the dynamic air flow in the natural environment, and cannot achieve the comfort of real natural wind; the speed control of the motor adopts open-loop control, and the control The accuracy is difficult to guarantee, resulting in obvious distortion between the control signal and the output wind speed

Embodiment Construction

[0019] Such as figure 1 , image 3 As shown, natural wind samples such as forest wind, ocean wind, and grassland wind are stored in the internal memory of the single-chip microcomputer. First, the corresponding relationship between the wind speed and the motor speed is established through experiments. The relationship obtains a motor speed, which is used as the given speed of the motor, and at the same time detects the actual speed of the motor through the Hall sensor, adjusts the PWM duty cycle of the microcontroller according to the deviation between the two, and corrects the actual speed of the motor in real time. Output wind speed.

[0020] In the natural environment, natural wind is a continuous random process. However, the control signal sample used for natural wind simulation is a discrete data sample within a limited time. To realize the simulation of natural wind, the periodic problem of limited data samples must be solved first. Under the premise of ensuring that ...

Abstract

The present invention discloses a natural wind simulating device. The device comprises a motor, a control device and a sensor, wherein the control device is connected to the motor, and used for outputing motor control signals so as to control the rotating speed of the motor; the sensor is connected to the control device, and used for detecting the status information of the motor and feeding the status information back to the control device; the rotating speed of the motor is controlled by the control device according to the status information.

Description

technical field [0001] The present invention relates to an air supply device and method, more particularly, to a device and method for simulating natural wind. Background technique [0002] At present, most of the air conditioners used in the indoor environment are mechanical air supply modes that only have directional, oscillating air supply, and direction selection changes. The air supply mode is monotonous, and the blowing experience is poor. Because the air flow velocity in the indoor environment is too low, the frequency change is small, and it is quite different from the natural environment. Being in such a thermoneutral environment for a long time will make the human body lack appropriate stimulation, which will cause people to reduce their ability to adapt to changes in the natural environment, resulting in Human body temperature regulation and resistance decline, which makes people susceptible to diseases such as colds and heatstroke. [0003] The dynamic air suppl...
