Abstract
The invention provides a method for realizing information transmission by taking visible light as a medium, relating to the technical fields of illumination, power supplies, integrated circuits, optics, communication, signal processing, networks, positioning and the like. According to the invention, the visible light is taken as an information transmission medium of an information emission component so as to realize information transmission. Compared with the traditional information transmission means, the method provided by the invention has the advantages of environment friendliness, rapidness, wireless property and safety.
Description
Technical field
The present invention relates to technical fields such as illumination, power supply, integrated circuit, optics, communication, signal processing, network, location.
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, 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 display floater 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 object of the invention is send out visible light a kind of new purposes---with the visible light is the method for media implementation message transmission.The present invention realizes transmission of Information with the information transmission medium of visible light as the information emission element.
The high speed electrical modulation 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 to throw light on, with wireless transmission high-speed data.Utilize the high level communication means to reach as high as the speed of per second hundreds of million to last 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 design of protocol and with existing cable network (xDSL, fiber, cable, powerline) and wireless network (FSO, WiMAX, LTE, 3G, interface WiFi).Really from the physical layer of system in netting 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 every function.The present invention's energy commercialization is also pushed the commercial market to, brings considerable economic.Application will be contained such as individual high, and family's high definition TV transmits, large scale business place shopping guide, intelligent driving etc.
In addition, recently increasing vehicular manufacturer begins to 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 the 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 brake or road early and select to prepare.If can answer support platform by the cooperation phasing with traffic department.
The present invention also can form the visible light navigation system, can be used as the position transducer that locating information is provided.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,, provide detail location and directional information to the user by building interior passage map or illuminating lamp position.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.
The message transmission means that the present invention is more traditional have environmental protection, quick, wireless, safe advantage.
Embodiment
The signal that one signal tower is sent by the direct transmission signals of visible light, can be a bit to some transmission, or a bit to multicast communication, also can be multi-multipoint transmission.
Can receive the relevant information that sends tower from signal by visible light as personal mobile phone.
The relevant information that terminal computer or the processing of other terminal, Medical Devices receive self-controller to send by visible light.
Automobile or aircraft receive the relevant informations of sending from control centre such as navigation by visible light; Or the like.
Claims (1)
1. be the method for media implementation message transmission with the visible light,, realize transmission of Information with the information transmission medium of visible light as the information emission element.
