Problems solved by technology

Most of the traditional electric fans use manual selection of fan gears (strong wind, medium wind, low wind) and mechanical timing shutdown within 1 hour. The gear timing is single and old-fashioned. The use is relatively unintelligent and humanized, while the market presents multi-function Electric fans are redundant and expensive

Embodiment Construction

[0034] see figure 1 , figure 2 , The intelligent controller includes a power supply circuit, a temperature detection circuit module, a main controller, an LCD display module, and a PWM drive circuit module. Temperature detection circuit module: connected with the main controller, use the temperature sensor to collect the ambient temperature, and directly output the digital temperature to the single-chip microcomputer JZ401 of the main controller for processing, and display the real-time temperature on the LCD display of the LCD display module, The detected current ambient temperature can be accurate to one decimal place. According to the detected temperature, compare the temperature zone settings of different gears in the single chip microcomputer, and set the speed of the fan motor. The PWM drive circuit module uses PWM pulse width modulation to change the speed of the DC fan motor. The single-chip microcomputer JZ401 drives and modulates the motor through the NMOS transi...

Abstract

An intelligent controller is characterized in that the intelligent controller comprises a power supply circuit which provides stable voltage for a temperature detection circuit module, a main controller, a liquid crystal display (LCD) module and a fan direct-current motor; a traditional fan is improved, the intelligent controller is added and can detect the temperature of indoor air and feed back the temperature of the indoor air for intelligent control, and therefore the rotating speed and other states of the fan can be controlled automatically, and energy conservation and environment friendliness are achieved. In consideration of the heat perception difference between children and adults, two different modes are designed for the intelligent controller to be selected, symptoms such as a cold caused by the wind bearing ability difference between people are reduced effectively, and thus the double purposes of user friendliness and intellectualization are achieved. The intelligent controller is very high in cost performance. The intelligent function of the intelligent controller is achieved through electronic elements such as an LCD and a printed circuit board (PCB). The intelligent controller is simply added to the traditional fan so that the intelligent control function can be achieved, and there is no need for significantly increasing the overall design cost of the fan.

Description

technical field [0001] The invention relates to a controller, in particular to an intelligent controller applied to electric fans. Background technique [0002] In most parts of our country in summer, choose to use traditional electric fans or air conditioners to cool down. Most of the traditional electric fans use manual selection of fan gears (strong wind, medium wind, low wind) and mechanical timing shutdown within 1 hour. The gear timing is single and old-fashioned. The use is relatively unintelligent and humanized, while the market presents multi-function Electric fans have many functions and are expensive. If the user chooses the air conditioner to cool down, the user is more likely to get air-conditioning disease and reduce the body's physique, especially children with weak physique are prone to colds and other conditions. [0003] Smart fan products have come out on the market one after another, with various production methods and gradually improved functions. Gene...
