Target tracking subsection power supply street lamp system

Abstract

The invention relates to a street lamp system, in particular to a target tracking subsection power supply street lamp system. The target tracking subsection power supply street lamp system comprises a microwave moving target signal detection circuit, a human body infrared detection circuit, a wireless communication circuit, an MCU (Micro Central Unit), a start control circuit, an auxiliary power supply, a light source and a commercial power input interface and is used for solving the conditions that low illumination utilization rate, low light-emitting efficiency of the light source and short service life of the lamp generally exist in the traditional city street lamp illumination, financial and physical resources consumed by the control flow of the illuminating system are great and the like; and the invention has the advantages that: firstly, target tracking and regional power supply illumination are adopted for effectively saving electric energy; secondly, the control over a lamp lightening zone is intelligently realized so as to effectively save labor force and financial resources; thirdly, an ICP (Inductively Coupled Plasma) or an LED (Light Emitting Diode) with high light-emitting efficiency is used to improve the utilization rate of electric energy; and fourthly, the idea of energy saving and emission reduction is accorded and green illumination is carried out.

Description

technical field [0001] The invention relates to a street lamp system, in particular to a circuit device for intelligently controlling the lighting of a street lamp area. Background technique [0002] At present, the existing street lamp control in our country mostly adopts methods such as semi-light lighting and interval lighting. The half-light lighting scheme is to maintain the original illuminance when the road is busy, and to control the street lamps to maintain a lower brightness when there are few people and vehicles by artificially reducing the voltage of the power grid. This method saves electric energy to a certain extent, but there are some defects. The main manifestations are: (1) Insufficient luminous flux; (2) The step-down technology is not mature enough, and the voltage is unstable, which affects the life of the lamp; (3) It poses a threat to traffic safety. The scheme of lighting at intervals is: turn on a light and turn off a light in the middle of the nig...

AI Technical Summary

Problems solved by technology

The main defect of this control method is: it is easy to cause the zebra effect, so that there are light dead zones in some road sections, shortening the sight and sight distance of pedestrians and drivers, and increasing many safety hazards

It can be seen that the existing street lamp control scheme not only has no obvious energy-saving effect, but also has many disadvantages, and the effect is not good in practical applications.
