Description
Technical field
Disclosure herein refer to a kind of visible light communication system, in particular to a kind of indoor visible light based on great power LED
Communication system.
Background technique
Visible light communication be using light emitting diode easily modulate with quick switchable feature, signal is passed through into LED component
Modulation, and received after propagating in air by optical receiver module, realize the reception to its optical signal and handle again.Visible light
The communication technology is broadly divided into indoor visible light communication and outdoor visible light communication two major classes, and wherein indoor visible light communication refers to
Communication function is taken into account while realizing illumination using LED.In recent years, domestic Many researchers were research emphasis to being based on
The visible light communication system direction of LED is drawn close, but the requirement of user is much not achieved in its bandwidth, modulation rate etc..Therefore it needs
A kind of indoor visible light communication system based on great power LED is designed, system bandwidth is increased, improves modulation rate.
Summary of the invention
The technical problem to be solved in the invention is to provide a kind of indoor visible light communication system based on great power LED,
Using high-power LED lamp, optimal indoor visible light communication system is designed, so that its system bandwidth be made to increase, gain is mentioned
It rises, modulation rate improves.
The technical scheme adopted by the invention is that: a kind of indoor visible light communication system based on great power LED includes:
MCU_1(1)；LED drives modulation circuit (2)；High-power LED module (3)；Optical receiver module (4)；Signal processing module (5)；
MCU_2(6)；Terminal (7).
The MCU_1(1) and MCU_2(6) it is all made of STM32 single-chip microcontroller, for realizing the function control of input/output terminal
System.
The high-power LED module (3) is made of high-power LED lamp (8), and totally 37 LED light sources, array are uniform
Arrangement is circle, both vertically and horizontally between upper every two LED light source between be divided into 2.5cm.
The optical receiver module (4) is managed using PIN, is believed for receiving the optical signal of LED sending, and by the light received
Number be converted to electric signal.
The signal processing module (5) includes pre-amplification circuit, filter circuit and shaping circuit etc., for connecing light
Electric signal after receiving module conversion is handled and is adjusted.
The terminal (7) is PC machine, printer, the communication equipments such as smart phone.
The beneficial effects of the present invention are: high-power LED light source is applied in indoor visible light communication system, can make be
Regiment commander is wide to increase, and gain is promoted, and modulation rate improves, and enhances its system performance.
Detailed description of the invention
Fig. 1 is a kind of composition block diagram of indoor visible light communication system based on great power LED；
Fig. 2 is a kind of structure chart of high-power LED module in the indoor visible light communication system based on great power LED.
Specific embodiment
The invention will be further described with example with reference to the accompanying drawing.
As shown in Figure 1, a kind of indoor visible light communication system based on great power LED, it is characterised in that: including MCU_1
(1)；LED drives modulation circuit (2)；High-power LED module (3)；Optical receiver module (4)；Signal processing module (5)；MCU_2
(6)；Terminal (7).
As shown in Fig. 2, high-power LED module (3) of the invention is made of white light LEDs (8), totally 37 white light LEDs light
Source, array are uniformly arranged as circle, both vertically and horizontally between upper every two LED light source between be divided into 2.5cm.
A kind of indoor visible light communication system based on great power LED, selects high-power LED as light emitting
Device applies in indoor visible light communication system, increases its system bandwidth, and gain is promoted, and modulation rate improves, and enhances
The performance of visible light communication system.
