Embodiment

[0032] Taking a certain room as the experimental site, the temperature range of the MCU program is set at 20°C to 30°C, the temperature sensor monitors the room temperature in real time, compares it with the temperature setting range of the MCU, the main program calculates the required duty cycle and transmits the data to Input the square wave generator to get a waveform with a duty cycle of 65% ( Figure 5 As shown), the duty cycle PWM wave drives the fan motor to realize the function of intelligent temperature control and speed adjustment. When the ambient temperature is high, the fan speed automatically increases; on the contrary, when the ambient temperature decreases, the fan speed automatically decreases. Driving the fan motor in this way can bring comfort to people and make people less likely to catch a cold. In addition, the fan motor is controlled by the output signal of the infrared pyroelectric sensor module to switch the bidirectional thyristor. Only when people a...

Abstract

The invention discloses a multi-mode induction intelligent energy-saving fan. According to the fan, a temperature control fan capable of automatically adjusting the rotating speed of a motor along with environment temperature changes is realized by designing a hardware system and a program, meanwhile, automatic starting and stopping can be achieved through infrared induction, and therefore energyis saved. The multi-mode induction intelligent energy-saving fan comprises a power module, a 51 single-chip microcomputer, a temperature sensor, a temperature display nixie tube, a square wave generator, a liquid crystal display, a bidirectional silicon controlled rectifier, an infrared pyroelectric sensor and a fan motor. The temperature sensor collects environment temperature and transmits the environment temperature to the 51 single-chip microcomputer, a PWM duty ratio wave is calculated and output through a temperature control module program to intelligently adjust the rotating speed of the fan motor, and the intelligent temperature control stepless speed regulation function is realized. In addition, an infrared pyroelectric sensor module is designed to automatically control the fan tostart and stop. The intelligent energy-saving fan saves electric energy and improves the comfort degree, and has important reference significance on the aspect of research on intelligent energy conservation and the like of other electric appliances.

Description

technical field [0001] The invention belongs to the technical field of fans, and in particular relates to a multi-mode induction intelligent energy-saving fan. Background technique [0002] Fan is one of the most common household appliances, and it is widely used in daily life due to its advantages of low cost, low energy consumption, and wide range of air supply. At present, the common fan speed in the market is divided into several gears, and the speed cannot be automatically adjusted according to the ambient temperature. If the temperature drops at night, it is easy to be caught by the fan. In addition, the fans are mostly controlled by key switches and remote control switches. The timing of the fans is generally limited to one hour. If people leave, there will be a waste of "people walking and fan turning". [0003] With people's pursuit of quality of life, the requirements for the intelligence of electric fans are constantly increasing. According to the literature sea...
