A kind of street lamp network control method and its network structure

Abstract

The invention discloses a streetlight network control method, comprising the steps of: immediately turning on a streetlight when the streetlight acquires a vehicle passing condition and measures a measured vehicle speed signal through a signal acquisition unit; meanwhile, commanding a plurality of streetlights ahead to be turned on for several seconds according to a preset corresponding value between the vehicle speed and the number of the turned-on streetlights ahead as well as a preset corresponding value between the vehicle speed and the light-on time; and turning off the streetlight after the vehicle runs through the streetlight. Meanwhile, by monitoring ambient brightness, vehicle traffic flow and ambient humidity and regulating the illumination brightness of the streetlight, invalid illumination is avoided. The control method disclosed by the invention has the advantages that the proper illumination brightness can be provided by the streetlights according to specific environments in bustling downtown areas and solitude road sections, and the electricity can be saved by 30%; and the method is completely adopted in the solitude road sections, the electricity can be saved by 70% in average and 90% at most. If an LED light source is adopted, the service life of the streetlight can be prolonged by 5 times.

Description

technical field [0001] The invention relates to a road lighting system, in particular to a dynamic and energy-saving control method of a street lamp network and its network structure. Background technique [0002] According to relevant statistics, the current global lighting electricity consumes about one-third of the world's energy, of which road lighting accounts for about 30% of the entire lighting. According to our statistical analysis, about 50% of global lighting is invalid lighting on average, and about 70% of road lighting is invalid lighting on average. The so-called ineffective lighting refers to the unnecessary lighting when people are not working or living and the excessive lighting when people are living and working. For example: in the middle of the night, there are no people (no cars) on the street lighting or there are a small number of people (cars) on the road, but at this time it is still high-standard lighting when there are many people and cars in the f...

Problems solved by technology

Its main features: the lamp has constant power and constant brightness within a certain period of time, which has nothing to do with human activities and the environment; there are also street lamps controlled by voice control, and a street lamp is lit when a vehicle passes by. This lighting method has limited sensitivity. At the same time, it cannot provide an effective safe lighting distance, the light range is too small, and there are potential safety hazards
