Distributed adaptive controlled intelligent road lighting system

Abstract

The invention discloses a distributed adaptive controlled intelligent road lighting system, comprising a plurality of independent adaptive lighting control devices, wherein each device comprises a singlechip, an infrared sensor and a photosensitive sensor. Each independent lighting device corresponds to a road lamp, and the adjacent lighting control devices carry out information communication via general I / O ports of the singlechips. Each independent lighting control system comprises an infrared sensing module, a brightness sampling module, a singlechip core board, a driving module, an information communication module and a lighting module. By analyzing external environmental signals, constant-brightness lighting of road lamps is realized when pedestrians and vehicles approach, and the brightness of the road lamps is controlled to a lower level in the absence of pedestrians and vehicles. The system is simple in control, strong in expandability and power-saving based on low cost.

Description

technical field [0001] The invention relates to an intelligent road lighting system, in particular to a distributed adaptive control intelligent road lighting system. Background technique [0002] With the continuous acceleration of the urbanization process in our country, the scope of the city is expanding, and the demand for urban traffic lighting is increasing day by day. While the city is bright and its image is beautiful, the cost of street lighting has also increased. [0003] Traditional street lamp lighting adopts integral control, that is, a piece of street lamp is controlled by a master switch, and only the operation of turning on and off. Traditional street lighting mostly uses gas discharge lamps such as high-pressure sodium lamps. There is a preheating process when starting up, which wastes resources and is not conducive to intelligent control. The traditional street light source uses the mechanism of mercury vapor to emit light, and the disposal of its waste ...

Problems solved by technology

[0007] The problem to be solved by the present invention is that, in view of the energy consumption and difficulty of recycling of traditional street light sources and the problem that emerging LED road lighting is still not intelligent enough, a distributed adaptive adjustment intelligent road lighting system is formed based on LED light sources and using single-chip microcomputers and sensors. , making the control of road lighting more intelligent while saving energy
