Terminal sends beacon, and beacon sends the indoor coordinate that content is beacon child servers, the first micro-control electricity of VLC beacon emissions terminals
The micro controller on road is received issues the data with beacon and time slot from beacon director server, makees pulse position to above-mentioned data
Modulated data are sent into LED drive circuit by modulation, then, in the time groove location that beacon director server gives, are passed through
Modulated data are equipped on visible light and are emitted by LED light source array；
The visible light signal received is converted to voltage signal, voltage signal quilt by the photoelectric switching circuit of VLC beacon reception terminals
It is sent into filter circuit to deal with, treated, and signal is sent into main amplifying circuit and makees enhanced processing, and amplified signal is sent into ratio
Signal processing is done compared with device circuit, and the micro controller of comparator treated signal is sent into the second micro-control circuit makees decoding process, obtains
The indoor coordinate of beacon child servers.
This system not only avoids the conflict that VISIBLE LIGHT EMISSION terminal generates over time and space, and also avoids
The interference of information between different LED light sources, more reliable scheme is provided for indoor positioning.
Compared with prior art, it is the advantages of this system：（1）Low cost, electromagnetic-radiation-free, is not applied easy care
Environmental restrictions；（2）The addition of beacon director server not only avoids information between adjacent LED light source by distributing, coordinating time slot
Interference, receiving terminal accurately receives the coordinate information from different LED indoors, and is easily managed the beacon of beacon child servers
Dynamically.
This system low cost, electromagnetic-radiation-free, is not limited by application environment, is easily managed easy care.
