Abstract

The invention discloses an LED visible light communication-based flow density statistics system. The system comprises a host computer, a transmitting terminal and a receiving terminal; the transmitting terminal is mounted on a ceiling, and comprises a transmitting circuit and an LED array; the receiving terminal is mounted on a floor and comprises a photoelectric detector and a receiving circuit; the host computer is connected with the transmitting circuit and the receiving circuit; the LED array and the photoelectric detector adopt a direct-injection type line-of-sight link. According to the system, the LED visible light communication technology is utilized to perform indoor flow and density statistics, so that not only is an indoor lighting requirement met, but also the flow density statistics alarming is realized. The method has the characteristics of being safe, efficient, high in quality, low in cost and convenient to use.

Description

technical field [0001] The invention relates to the technical field of LED visible light communication, in particular to a system and method for counting people flow density based on LED visible light communication. Background technique [0002] The low-power and high-density LED lighting source is a new small-sized LED packaging form derived from the market's demand for projection lighting sources. Because LED visible light lighting equipment has many advantages such as high integration, low price, low energy consumption, long life, high safety, high lighting brightness, and strong adaptability, it has gradually become the best choice for indoor and outdoor lighting sources. The maturity and wide application of LED lighting technology have brought new opportunities for the development of visible light communication. [0003] During holidays and events, in some large squares, shopping malls and other indoor places, there will be a sudden increase in the density of people. ...
