Safe and energy-saving control system for fan

Abstract

The invention relates to a fan safety and energy-saving control system. When a human body infrared sensor detects human body infrared rays and inputs a signal to a processing module, the processing module controls the pressure sensor, anemometer and temperature sensor to start operation, and controls the fan according to the signals in the anemometer and temperature sensor The running speed and stop operation of the motor; during the start-up and operation of the fan motor, when the pressure sensor inputs the pressure signal to the processing module, the processing module controls the fan motor to stop running and controls the alarm to alarm; When no signal is input to the processing module, the processing module controls the pressure sensor, the anemometer, the temperature sensor and the fan motor to stop running or remain in a non-starting state. Therefore, the working state of the fan motor is reasonably controlled through the human body infrared sensor, pressure sensor, air flow rate and temperature to ensure the comfort of the user's environment, optimize the user experience, save energy and improve the safety of the fan.

Description

technical field [0001] The invention relates to the technical field of fan control, in particular to a fan safety and energy saving control system. 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 nee...

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

[0005] In addition, during the use of the fan, sometimes human hands and fingers accidentally extend into the blades from the grille of the fan, causing the hands and fingers to be stirred by the blades, causing safety accidents, especially for those with weak safety awareness For children or certain groups of people, the chances of causing safety accidents are greater
