LED室内定位发射端研究与设计

LED indoor positioning transmitter drive circuit is designed in this paper, the tests show that the communication rate can reach 1Mbps. This paper set the LED indoor positioning system, through using the method of meshing to test receive plane illuminance values by lux meter, and researching the illuminance distribution in three dimensional space. On this basis, the transmitting terminal and receiving end joint test to study the actual location. The experiments prove that the design of the transmitter can achieve cm level positioning accuracy in the proposed positioning model. This article provides LED indoor location transmitter design which applied strong reference method.
