specific Embodiment approach 1

[0024] Embodiment 1. Persistence of vision fan based on the Internet of Things, which includes a motor 3, a fan blade 4 and a power supply 7, the center of the fan blade 4 is fixed on the output shaft of the motor 3; the power supply terminal of the motor 3 is connected Input power supply 7; the motor 3 is used to drive the fan blade 4 to rotate; it includes the Arduino core board 1 and N running lights 6, N is a positive integer; the N running lights 6 are distributed and fixed on the fan blade 4, and N running lights 6 are connected in parallel and then connected to the power supply 7;

[0025] The control signal input end of described water lamp 6 is connected with the control outlet of the water lamp control switch of Arduino core board 1;

[0026] The control signal sent by the Arduino core board forms a virtual persistent visual screen 5 on the fan blade 4;

[0027] The invention is a small fan based on Arduino and persistence of vision technology. The fan has strong us...

specific Embodiment approach 2

[0030] Embodiment 2. The difference between this embodiment and the persistent vision fan based on the Internet of Things described in Embodiment 1 is that it also includes a transmission 2, and the transmission 2 is arranged between the motor 3 and the power supply 7; The transmission 2 is used to control the rotation speed and steering of the motor 3; it is also used to adjust the clarity or stability of the virtual persistent visual screen.

[0031] The speed changer 2 in this embodiment can adopt the model produced by Shenzhen SEG Electronics as: a general-purpose PWM pulse width DC motor governor, its operating voltage: DC12v-DC36v, rated 5a, instantaneous maximum current 10A, with speed zero adjustment and Adjust the maximum function.

specific Embodiment approach 3

[0032] Specific embodiment three. The difference between this specific embodiment and the Internet of Things-based visual persistence fan described in specific embodiment one is that it also includes a temperature and humidity sensor 10, and the temperature and humidity sensor 10 is used to detect on-site temperature and humidity, so The temperature and humidity signal output end of the temperature and humidity sensor 10 is connected with the temperature and humidity signal input end of the Arduino core board 1; the Arduino core board 1 is controlled to form a virtual visual on the fan blade 4 according to the infrared control signal sent by the infrared receiving device 8 Persist the image on the screen.

[0033] According to the temperature and humidity signal detected by the temperature and humidity sensor 10, the Arduino core board controls the fan blade 4 to form a virtual persistence of vision screen to display the temperature and humidity value.

Abstract

The invention discloses a vision persistence fan under the Internet of Things and an application method of vision persistence images on the fan, and relates to the vision persistence field, and aims at solving the problems that an existing fan based on vision persistence is poor in user experience and limited in application crowd. The invention discloses a small fan based on Arduino and a vision persistence technology, and the fan is high in user experience, very wide in application crowd and suitable for people of all ages.

Description

technical field [0001] The invention relates to the field of persistence of vision. Background technique [0002] The earliest use of the persistence of vision effect in history was in the production of movies. The speed of pictures broadcast on the movie screen is 25 pictures per second. Under the effect of the phenomenon of persistence of vision, the human eye will feel that these intermittent broadcast Pictures are in motion. [0003] At present, persistence of vision already has a relatively mature supporting technology. There is a holographic 3D smart screen that uses persistence of vision to achieve 3D effects. From a market perspective, in the south every July and August, the temperature is usually above 35 degrees Celsius, while schools Air conditioners are rarely installed, so portable electric fans have a large market among primary and middle school students. Compared with ordinary electric fans, a portable electric fan that can form rolling patterns on the fan su...
