Embodiment Construction

[0032] Unless otherwise specified, the materials and equipment used in the present invention can be purchased on the market.

[0033] see figure 1 , the present invention is an on-site road lighting system, which is composed of a plurality of interconnected street lamp units in the application scene. A single street lamp is independently controlled and there is a bidirectional flow of information between two connected. Once a street lamp unit senses the infrared signal of a person or vehicle, the single-chip microcomputer immediately transmits the signal to the adjacent two street lamp units connected to it, that is, as long as the presence of a person or vehicle is sensed, at least three street lamps connected in sequence will light up. . The figure shows the layout on one side of the road. In the actual road lighting, both roads adopt this layout and remain independent of each other. The power partition blocks of all street lamps are controlled by the remote central contro...

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 ...
