City road lamp management system based on LiFi (Light Fidelity) technology

Abstract

The invention discloses a city road lamp management system based on a LiFi (Light Fidelity) technology. The system comprises road lamps distributed on city roads. The road lamps are LED road lamps. The system also comprises a LiFi base station, wherein the LiFi base station comprises optical fiber links, and the LiFi base station is used for establishing connection between an access end and an internet end, processing electric signals and receiving and / or sending the electric signals; a centralized control chamber which communicates with the LiFi base station through the internet, wherein a server and a display screen are arranged in the centralized control chamber; and controllers which are mounted on the LED road lamps and are used for controlling the work of the LED road lamps. The monitoring cameras are mounted on the LED road lamps. The monitoring cameras are in communication connection with the controllers. Photoelectric communication devices are arranged on the LED road lamps. The photoelectric communication devices comprise LED drivers, LEDs, PIN photoelectric diodes and trans-impedance amplifiers. The controllers are in communication connection with the photoelectric communication devices of the LED road lamps through receiving ends.

Description

technical field [0001] The invention relates to an urban street lamp management system, in particular to the centralized control of street lamps on urban roads. Background technique [0002] In the prior art, most of the street lamps on urban roads use LED street lamps; LED street lamps are energy-saving, environmentally friendly and have a long service life; the street lamp control of existing urban roads is still decentralized, and each street lamp has a controller; it needs to be debugged on site; the workload is very high Big; [0003] At the same time, visible light communication (Light Fidelity) has gradually matured. It has fully realized the function of connecting a 1W LED lamp bead in the laboratory, and the function of connecting 4 computers to the Internet under the light, and the highest speed reaches 3.25G. Contents of the invention [0004] The technical problem to be solved by the present invention is to address the deficiencies in the above-mentioned prior...
