Problems solved by technology

[0003] The function of the existing electric fan is relatively simple, and the control of the working state of the electric fan needs to be done manually by the user, manually adjusting the gear of the mechanical fan or manually operating the remote control of the electric fan to adjust the speed of the electric fan, etc.
[0004] After people enter the indoor fan area from the hot outdoors, the skin temperature of the human body is relatively high, and there is sweat. If the wind speed is too small, the temperature of the human skin will drop too slowly, which will cause the human body to be in a high heat state for a long time, and will also make the human body feel uncomfortable.

Embodiment 1

[0043] In the structural setting of the present invention: the outer circle of the fan head is provided with a fan head frame, and two groups of infrared temperature sensors are symmetrically distributed on the fan head frame. An infrared distance sensor is installed between adjacent infrared sensors on the same side of the fan head frame, and an air speed sensor for sensing and monitoring the real-time wind speed of the fan is installed on the inner periphery of the fan head frame. There is an angular velocity sensor. Inside and outside, the fan comfort wind speed control system is equipped with an atmospheric pressure sensor for sensing and monitoring the external atmospheric pressure.

[0044] The rotation mechanism of the fan head is equipped with a steering sensor. The steering sensor detects the steering trend of the current fan head. After the main processing controller analyzes and judges the current shaking direction of the fan head, it drives the sensors on the steer...

Embodiment 2

[0046] In the sensor sensing detection of the present invention: the comfort wind speed control system includes a main processing controller, the main processing controller obtains the human body temperature information detected by the infrared sensor in real time, and the main processing controller according to the currently detected human body temperature information The temperature information is analyzed to match the comfortable wind speed on the surface of human skin. The main processing controller obtains the distance parameter between the human body and the fan head detected by the infrared distance sensor; the main processing controller obtains the wind speed of the fan head monitored by the wind speed sensor; the main processing controller obtains the current rotation of the fan head direction and angular velocity of the fan head. The main processing controller drives the acquired real-time information detected by the infrared temperature sensor, the infrared distance s...

Embodiment 3

[0048] The main processing controller linearly analyzes the weakened wind speed at the position of the human body according to the obtained distance parameters between the human body and the fan head and the current wind speed at the side of the fan head.

[0049] A database of wind speed attenuation characteristics of wind speed along with flow distance is preset in the main processing controller. Let the real-time wind speed detected by the wind speed sensor from the fan head be V, and let the distance between the human body and the fan head detected by the infrared distance sensor be L. The main processing controller analyzes the weakened wind speed reaching the position of the human body according to the relationship between the wind speed V and the distance L between the human fans, and sets it as Vs.

[0050] Process the fan head wind speed V and human fan distance L obtained in the controller, analyze and calculate the weakened wind speed Vs under the current state cond...

Abstract

The invention discloses a fan comfortable air speed regulation and control system based on multi-dimensional monitoring analysis, and relates to the technical field of fan driving control. According to the fan comfortable air speed regulation and control system based on multi-dimensional monitoring analysis, a main processing controller linearly analyzes current weakened air speed which arrives atthe position of a human body location; the main processing controller analyzes a current time interval of turning and direct blowing of a fan head according to acquired angular speed of the fan headand angle difference between a main air area of the fan head and the monitored position of the human body location; and the main processing controller outputs an air speed regulation state or a motorpower regulation state required by the fan head currently according to a relation value between the weakened air speed and comfortable air speed on the surface of human skin and the current time interval of turning and direct blowing of the fan head. According to the fan comfortable air speed regulation and control system based on multi-dimensional monitoring analysis, air outlet speed of the fanhead is rapidly and effectively regulated and controlled in an adaptive mode, so that the air speed right facing the position of the human body location is in a comfortable state, and the air blowingcomfortable experience effect of people in various physical states is improved.

Description

technical field [0001] The invention belongs to the technical field of fan drive control, in particular to a fan comfort wind speed control system based on multi-dimensional monitoring and analysis. Background technique [0002] As a common electrical equipment in summer, electric fan is used to blow and dissipate heat for people. Because it has advantages such as small size, low price and easy use, it has become more and more popular among people. [0003] The function of the existing electric fan is relatively simple, and the user needs to manually control the working state of the electric fan, such as manually adjusting the gear of the mechanical fan or manually operating the remote control of the electric fan to adjust the speed of the electric fan. [0004] After people enter the indoor fan area from the hot outdoors, the skin temperature of the human body is relatively high, and there is sweat. If the wind speed is too small, the temperature of the human skin will dro...
