specific Embodiment 1

[0035] The present invention provides a kind of driving method of LED three-dimensional display based on Internet of Things, comprises the following steps:

[0036] Step 1: Collect sound signals through the audio input interface, identify them through the music rhythm recognition module, and filter the sound signals;

[0037] The music rhythm recognition module recognizes the time interval between the forte dong and the sub-forte da at about 0.5-1 second. The sampling time is 4 beats, about 2-4 seconds. The total sampling time T is set to 2 seconds. The number of sampling points N is 128 points, and the calculated sampling interval is t=T / N=2 seconds / 128=15.625 milliseconds, that is, music sound intensity is sampled every 15.625 milliseconds, and a total of 128 samples are taken.

[0038] Step 2: Receive the screened sound signal through the MCU, convert the sound signal into a frequency domain signal, and output the frequency domain signal to the NBIOT IoT module; layer selec...

specific Embodiment 2

[0092] This embodiment is a driving method for displaying, translating, rotating, and other effects of graphics such as points, lines, planes, triangles, circles, bitmaps, cubes, spheres, and columns in an LED three-dimensional display based on the Internet of Things. illustrate.

[0093] 1D vector graphics

[0094] Features of vector graphics:

Abstract

The invention is a driving method of an LED three-dimensional display based on the Internet of Things. The invention relates to the technical field of three-dimensional stereoscopic displays. The audio input interface collects sound signals, recognizes them through a music rhythm recognition module, and screens the sound signals; receives the sound signals after layer selection and row selection through an MCU, and converts the sound signals into frequency domains. Signal, the frequency domain signal is output to the NBIOT Internet of Things module; screened and output to the LED light cube; the invention adopts self-adaptive webpage design, and users can realize on-site viewing and Control live LED light cube display content and animation effects. Use Ajax technology to update the data display part of the webpage in real time without reloading the webpage. At the same time, you can use the intelligent control scheme to realize the display of the specified content and animation effect at the specified time and condition.

Description

technical field [0001] The invention relates to the technical field of indoor three-dimensional displays, and relates to a driving method for LED three-dimensional displays based on the Internet of Things. Background technique [0002] The LED display device has powerful display capabilities, and can display dynamic effects such as Chinese characters, graphics and animations in three dimensions. Combined with the music and the spatial layout of the building, the LED display device can realize all kinds of fantastic and dynamic shapes, and create an art space with various theme scenes on the three-dimensional surface. It has good permeability, strong three-dimensional sense, rich creativity and communication space. The advantages of large size, long viewing distance, and various specifications can meet the needs of various application scenarios. [0003] At the same time, it realizes the function of dynamically displaying clock, date, and weather information, and organically...
