Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, 2, a kind of intelligent electric fan, including the motor with rotating shaft, flabellum, the base with support bar,
Control module, PWM speed adjusting modules, temperature sensor, human body infrared thermometer.
The control module is the embedded microprocessor of STM32 series, such as STM32F429IGT6.The speed governing mould
Block is PWM SG1525 modules, and it is made up of tachometer circuit and PWM alignment circuit two parts.Both are all ripe production on the market
Product.
The motor is arranged horizontally at the upper end of support bar, and the flabellum is arranged in rotating shaft, in order to protect electricity
Machine and flabellum, can equally set a protective cover, protective cover is fixed on support bar, for fixing motor, while front end is set
There is netted grid, for guiding the wind that flabellum is blown out.
The chassis interior is provided with cavity, the control module (STM32F429IGT6) and PWM speed adjusting modules (PWM
SG1525) it is built in cavity, temperature sensor and the human body infrared thermometer is embedded on support bar, and both pass through wire
It is connected to control module (STM32F429IGT6) input.The temperature sensor is arranged on one that support bar deviates from flabellum
Face, thus, the wind of flabellum blowout do not interfere with judgement of the temperature sensor to indoor temperature.Human body infrared thermometer is located at support
On bar, optimal to be located at same direction with flabellum, the PWM speed adjusting modules (PWM SG1525) are located at the output of control module
End, the motor is located at the output end of PWM speed adjusting modules (PWM SG1525).
The indoor temperature of the temperature sensor detection, and electric signal is converted into control module, for example, temperature sensor
The temperature for detecting interior is 21 degree, and numerical signal is converted into after electric signal and is sent to control module by it
(STM32F429IGT6)。
The human body infrared thermometer detects the temperature of human body surface, and is converted into electric signal to control module, for example, warm
The temperature that degree sensor detects interior is 36 degree, and numerical signal is converted into after electric signal and is sent to control module by it
(STM32F429IGT6)。
