Abstract
The invention relates to an information transmission system using visible light as media. The information transmission system comprises a transmitting end, transmission media and a receiving end. The transmission media are the visible light. The transmitting end is a transmitting mechanism which is provided with an LED lamp or an LED lamp array. Compared with a traditional information transmission means, the information transmission system using the visible light as the media has the advantages of being environmentally friendly, swift, wireless and safe.
Description
Technical field
The present invention relates to the technical fields such as a kind of illumination, power supply, integrated circuit, optics, communication, signal processing, network, location, relate in particular to a kind of information transmission system take visible light as medium.
Background technology
Illuminating lamp is from incandescent lamp, fluorescent lamp, electricity-saving lamp, develop into solid LED illuminating lamp of new generation now, white-light illuminating LED has high strength, high efficiency, small size, low cost, easy care, the remarkable advantage such as pollution-free, along with the green non-pollution energy with energy-conservationly become global hot issue, white-light illuminating LED will replace traditional illumination gradually with incandescent lamp and fluorescent lamp.They can be used for making multi-functional demonstration panel simultaneously, and video screen shows, automobile front lamp, taillight, and traffic lights.But up to the present, the purposes of visible light is not also broken the functional category of illumination and demonstration.
Summary of the invention
The new purposes of a kind of visible light of discovery that the object of the invention is---take the method for visible light as the media implementation communication.The present invention realizes the transmission of information with the information transmission medium of visible light as the information transmitting parts.
Technical scheme of the present invention is: described system comprises transmitting terminal, transmission medium and receiving terminal, and described transmission medium is visible light; Described transmitting terminal is the trigger mechanism that is equipped with LED lamp or LED lamp array.
The High-speed Electric modulating performance of white light LEDs (the fastest can to tens megahertzes) shows that they also can be used as communication light source when being used for illumination, with wireless transmission high-speed data.Utilize the high level communication means to reach as high as per second hundreds of million to the speed of upper GB.The present invention can realize that the place of visible light all can communicate by letter whenever and wherever possible, as the measurement of: the framework of high-speed communication local area network (LAN), LED illumination and the coordination of communicate by letter, LED driving, communication link and modeling, communication performance comprehensive assessment, duplex communication scheme, multi-user embed Protocol Design and with existing cable network (xDSL, fiber, cable, powerline) and wireless network (FSO, WiMAX, LTE, 3G, WiFi) interface.Really from the physical layer of netting interior system to network layer, application layer and internetly do systematization research, design and demonstration.System of the present invention also can be with based on existing commercial illumination LED s, and integrated software and hardware and one are to realize above-mentioned various functions.The present invention's energy commercialization is also pushed the commercial market to, brings considerable economic benefit.Application will be contained such as individual high－speed networking, and family's high definition TV transmits, large scale business place shopping guide, intelligent driving etc.
The communication means that system of the present invention is more traditional have environmental protection, quick, wireless, safe advantage.
Description of drawings
Fig. 1 is work schematic diagram of the present invention.
Embodiment
A kind of information transmission system take visible light as medium, described system comprises transmitting terminal, transmission medium and receiving terminal, described transmission medium is visible light; Described transmitting terminal is the trigger mechanism that is equipped with LED lamp or LED lamp array.
Embodiment 1
Equip new vehicle with white light LEDs.Traffic control and urban construction unit also replace traffic lights and street street lamp with white light LED array.The present invention also can be between vehicle, can realize communicating by letter between vehicle and traffic lights.State and peripheral traffic as traffic lights all can in time be sent to the driver, carry out early brake or road and select to prepare.With traffic department if the cooperation phasing is answered support platform.
Embodiment 2
In large complicated place, building, in the building, avenue, residential quarters, the LED lamp will spread all over the world.Can form the white light guider, embed mobile phone or other palm type electronic device, by building interior passage map or illuminating lamp position, provide detail location and directional information to the user.Thereby realize GPS in the indoor function that can't realize, or strengthen outdoor function.High level communication agreement, location and guidance algorithm can be embedded in hand-held electronic products.
Embodiment 3
The signal that one signal tower is sent by the direct signal transmission of visible light, can be a bit to some transmission, or a bit to multicast communication, can be also multi-multipoint transmission.
Embodiment 4
Personal mobile phone can receive the relevant information that sends tower from signal by visible light.
Embodiment 5
The relevant information that terminal computer or the processing of other terminal, Medical Devices come self-controller to send by visible reception.
Embodiment 6
Automobile or aircraft receive the relevant informations such as navigation of sending from control centre by visible light.
