OOK is modulated and is added on LED light source, realizes the wireless LED visible light communication of low speed.But the research is in ideal letter
It is proposed under road and reception situation, and transmission quality is not high, system communication distance is also closer, concrete application is also unrealistic.
Japanese KEIO university Kitano professor et al. proposed LED highway lighting communication system [21] in 2003, in LED highway
The quality of the letter to credit ratio under different receiving direction angles and field angle is analyzed in illumination communication system, and in certain bit error rate
The relationship of lower letter to credit ratio and receiving data rate, it is believed that LED visible light highway lighting communication system is communicated better than infrared highway communication
System.LED traffic lights is had also been proposed later, the traffic lights that is constituted before and after automobile between LED lamp to automobile and automobile headlamp to vapour
Tail-light these two types line-of-sight propagation.In 2006, the LED of Wook professor and Komine et al. to traffic lights to automobile
After visible light communication system is analyzed [22], it is believed that be better than using snowslide using the receiver performance of two-dimensional image sensor
The receiver of photodiode.In terms of modulation system, on the basis of studying infrared modulated, Zahedi professor Edmond etc.
People, which proposes, to be utilized using the basic digital modulation mode such as OOK and PPM to improve visible light communication system channel capacity and light wave
The theory [23-25] of rate.
The citation of above-mentioned data, the development only exchanged from visible light with wireless technology, provides reference.
The first patent of applicant " one kind is based on separated type circuit design method " (Chinese Patent Application No.
201210353012.3,201210474371.4), it is desirable to provide one kind can be applied to various individuals under the conditions of existing hardware
In the circuit of appliance and electronic, to adapt to the circuit of incompatible replacement each other, it is based on separated type circuit design method.This technology is answered
With wireless communication technique and permission is characterized by using authentication management, general replacement module hardware circuit meets the needs of using.
Split circuit are as follows: by industrial design, allow same circuit having the propulsion of adaptation guide groove intracavitary, separation is alternatively to difference
In product, has and economize on resources, convenient for users to the effect of experience.Circuit is split to like with self-contained system and user
Software setting, or can synchronize user it is another split circuit hobby software setting.
Or the first patent of applicant " one kind is based on separated type circuit design method " (Chinese Patent Application No.
201310257261.7), it is related to a kind of based on separated type circuit design method.It is characterized in that curved-surface display end, aobvious for equipment
Presentation surface；Curved-surface display end bottom is attached integral by being adapted to convex/recessed laminated surface with the circuit split.Or disassembly replacement
Power supply unit；The power supply unit bottom of disassembly replacement is adapted to convex/recessed laminated surface, attaches with the circuit split integral.Point
