Abstract
The utility model belongs to local area network (LAN) constructing technology field, particularly a kind of indoor local area network structure based on visible light communication.Should based on the indoor local area network structure of visible light communication, comprise and be arranged at indoor computer and Homeplug, it is characterized in that: described Homeplug is connected with visible ray hub, visible ray hub is connected with photoelectric detector with white LED lamp respectively, computer is connected with station adapter, and station adapter is provided with directed LED.The beneficial effects of the utility model are: signal attenuation is little, the error rate is low, quorum sensing inhibitor consistency strong, local signal can not be caused unstable, electromagnetic spectrum can be applied for, effectively reduce the environmental pollution that electromagnetic radiation causes, due to easily the blocking property of light, effectively can solve when conventional method builds local area network (LAN) and leak the secret leaking problem caused because of internal home network signal electromagnet.
Description
(1) technical field
The utility model belongs to local area network (LAN) constructing technology field, particularly a kind of indoor local area network structure based on visible light communication.
(2) background technology
When each terminal of house interior takes netting twine interconnected, the slightly long then signal attenuation of circuit becomes large, and the error rate increases, and affects attractive in appearance; When indoor each terminal is as taked WIFI interconnected, then electromagnetic radiation can be produced, contaminated environment, and when relying on WIFI to carry out Signal transmissions, also by periphery electromagnetic environment and building scenes (wall thickness, amount of reinforcement etc.) impact, cause quorum sensing inhibitor consistency poor, even local signal is unstable, due to the radiation feature of electromagnetic signal, also there is the hidden danger that user profile is leaked.When adopting WIFI interconnected in room, then electromagnetic radiation can be produced, contaminated environment, and when relying on WIFI to carry out Signal transmissions, also by periphery electromagnetic environment and building scenes (as wall thickness, layout structure, wall steel bar consumption etc.) impact, quorum sensing inhibitor is uneven, respective regions no signal or jitter, due to the radiation feature of electromagnetic signal, also there is the hidden danger that user profile is leaked.
(3) summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides a kind of cost-saving, simple operation, stability and highly, easy to maintenance reduces environmental pollution, avoids the indoor local area network structure based on visible light communication of divulging a secret.
The utility model is achieved by the following technical solution:
A kind of indoor local area network structure based on visible light communication, comprise and be arranged at indoor computer and Homeplug, it is characterized in that: described Homeplug is connected with visible ray hub, visible ray hub is connected with photoelectric detector with white LED lamp respectively, computer is connected with station adapter, and station adapter is provided with directed LED.
The beneficial effects of the utility model are: signal attenuation is little, the error rate is low, quorum sensing inhibitor consistency strong, local signal can not be caused unstable, electromagnetic spectrum can be applied for, effectively reduce the environmental pollution that electromagnetic radiation causes, due to easily the blocking property of light, effectively can solve when conventional method builds local area network (LAN) and leak the secret leaking problem caused because of internal home network signal electromagnet.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
In figure, 1 computer, 2 Homeplugs, 3 visible ray hubs, 4 white LED lamps, 5 photoelectric detectors, 6 station adapters, 7 directed LED.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises the computer 1 and Homeplug 2 that are arranged at indoor, Homeplug 2 is connected with visible ray hub 3, visible ray hub 3 is connected with photoelectric detector 5 with white LED lamp 4 respectively, and computer 1 is connected with station adapter 6, and station adapter 6 is provided with directed LED 7.
Adopt a kind of indoor local area network structure based on visible light communication of the present utility model, in room, communication link mainly comprises: the part such as visible light communication hub (VLC hub), photoelectric detector, station adapter, white LED lamp.For convenience of describing, the communication link in room is divided into forward direction route and reverse route.In forward direction route, in room, Homeplug 2 demodulates network data from formatted data bag, after this network data sends into visible ray hub 3, data to be modulated onto in spectrum via white LED lamp 4 in a broadcast manner to each subscriber computer 1 terminal transmission, for ensureing signal stabilization, indoor can arrange multiple white LED lamp 4(and be called main light source) form LED array, these white LED lamps 4 are except the transmission of undertaking network data, also bear the task of room lighting, indoor each computer 1 terminal completes light signal by the station adapter 6 receiving terminal receiving optical signals arranged respectively and changes to the signal of telecommunication and demodulate network data, judge whether to one's name packet by the station address in packet, if it is receive, otherwise just abandon.In reverse route, the data of computer 1 terminal are modulated in spectrum through station adapter 6 transmitting terminal, user's light source is called by the directed white LED lamp 7(on station adapter 6, emission area is less, and be adjusted to directional illumination state), transfer to the photoelectric detector 5 on roof, light signal is reduced into the signal of telecommunication by photoelectric detector 5, this signal of telecommunication processes further through visible ray hub 3 and restores user data and pack the data to network data according to the universal standard, determine that each computer 1 terminal room transmits or outwards transmits through Homeplug 2 in indoor according to destination address.Visible ray hub 3 is core components of internal home network structure, it had both been responsible for receiving the information from house computers terminal, extranet information is received again by Homeplug 2, then at times by the information received by main light source to indoor each computer 1 terminal broadcast (each computer 1 terminal determines whether extract each packet according to the destination address of packet), it is connected with external network through Homeplug 2 in addition, realizes exchange and the transmission of network data between internal-external network.
