Intelligent linkage street lamp controller

Abstract

The invention discloses an intelligent linkage street lamp controller, which comprises a single-chip microcomputer U5, linkage signal input / output ports CN2 and a control power supply circuit. The input end of the single-chip microcomputer U5 is connected with an ambient light illuminance detection circuit, a time setting circuit, a moving object / human sensor and a linkage signal input circuit; the output end of the single-chip microcomputer U5 is connected with a linkage signal output circuit, a timing signal output interface, a turning-on / low-light output circuit and a high-light signal output circuit; the plurality of linkage signal input / output ports CN2 of the street lamp controller are connected through a control bus to form a linkage street lamp group; and the control bus is connected with a central controller to enable street lamps in the linkage street lamp group to realize priority remote centralized control. The intelligent linkage street lamp controller can also realize local intelligent turning on / off, low-power low-light lighting or high-power high-light lighting, so that the controller not only can ensure lighting needs of pedestrians and vehicles, but also can greatly reduce energy consumption; and the controller has the advantages of simple and reasonable structure and environmental protection and energy saving and the like.

Description

technical field [0001] The invention relates to a street lamp, in particular to an intelligent street lamp controller. Background technique [0002] The patent document with the publication number "CN105258023A" discloses a self-controlled street lamp including a street lamp. The technical solution adopted is to provide a sensor and a time delay switch on the street lamp, and the street lamp is connected to the controller. When this kind of self-controlled energy-saving street lamp is used, it senses whether there are people around the street lamp according to the sensor, and then provides illumination to pedestrians under the action of the delay switch, and turns off the street lamp after the pedestrian leaves to save energy. [0003] Generally speaking, after 12 o'clock in the evening in big cities and 10 o'clock in the evening in small and medium-sized cities, LED lamps run at low power and low-brightness lighting in an energy-saving mode, and the motion detectors of the ...

AI Technical Summary

Problems solved by technology

Due to the fast movement speed of motor vehicles, when the LED lamps are operated from low power, the energy-saving working mode of low-brightness lighting to high-power operation, high-brightness lighting working mode of high-brightness lighting, the high-speed moving motor vehicles have already passed the Therefore, the technical solutions disclosed in the above patent documents do not achieve the effect of intelligent lighting and safe travel
