Intelligent fan control method

Abstract

The invention relates to a fan intelligent control method: detecting and judging whether there is human body infrared rays in the current environment, and if there are human body infrared rays, the following steps are performed: 1) obtaining the air flow velocity and temperature of the current environment; 2) according to the current environment air flow velocity and The temperature controls the running state of the fan motor; and, if there is no human infrared ray, controls the fan motor to stop running. The present invention judges whether there are human infrared rays in the current environment, judges whether there are users, and determines whether the fan needs to be turned on, so as to automatically start and stop reasonably, save energy, and further combine the air velocity and temperature after turning on to control the fan reasonably The working state of the motor ensures the comfort of the user's environment to better meet the needs of the user and improve the user's experience, and the fan can automatically stop running when it is not in use, or reduce the speed under certain environmental conditions, Conducive to environmental protection and energy saving.

Description

technical field [0001] The invention relates to the technical field of fan control, in particular to an intelligent control method for a fan. Background technique [0002] A fan is a device that generates airflow through electric drive. The motor configured in it drives the fan blades to rotate after being energized, and converts electric energy into wind energy to achieve the effect of generating wind and cooling. [0003] Existing fans generally have three control gears, which are respectively used to control the rotation speed of the motor to generate different wind speeds, so as to satisfy applications in life or industry. During use, when the user feels the current environment is stuffy, he will start the fan himself, and select the air volume blown by the fan through the control switch on the fan, thereby achieving the purpose of cooling. After using for a period of time, if the user feels that the current ambient temperature is low and causes discomfort, he needs to ...

Problems solved by technology

[0004] In this way, no matter whether the user needs to start the fan or stop the fan, it must be executed by the user himself, which will have a certain impact on the user experience, and the user must feel uncomfortable before changing the running state of the fan. can adversely affect the user experience

At the same time, after the user turns on the fan but does not need to use it, the fan is still in the starting state, which will cause a certain waste of resources, which is not conducive to environmental protection and energy saving
