Single lamp energy saving controller for road lamp and control method

Abstract

The invention discloses a single-lamp energy-saving controller for street lamps and a method thereof. The single-lamp energy-saving controller comprises a central processor, as well as a street lamp working-status collection interface, a street lamp current/voltage acquisition interface, a multi-lamp control expansion interface, a power carrier communication interface and a power-cutback ballast control interface which are respectively connected with the central processor. The power line carrier communication interface is connected with a spread spectrum power carrier communication module; the power-cutback ballast control interface adopts strong/week current isolation and two-stage drive and receives switching value signals output from the central processor. The method includes the following steps of: device parameter initializing, state detection, new data detection, received new data processing, timing control processing detection, timing control processing and watchdog removing. The single-lamp energy-saving controller does not cause the pollution of the power grid environment or other adverse effects; simultaneously, based on the strong capacity of resisting power grid disturbance, the single-lamp energy-saving controller can carry out power cutback operation according to the preset time sequence, when in use separately, thereby achieving the energy-saving effect.

Description

technical field [0001] The invention relates to a street lamp controller and a control method, in particular to a street lamp single-lamp energy-saving controller and a control method. technical background [0002] In the existing technology, street lamp controllers usually pollute the grid environment or cause other impacts. At the same time, the ability to resist the grid is not strong. Traditional voltage regulation, phase shifting, including frequency conversion control, etc. may have unpredictable effects on the life of the street lamp light source. influences. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide a street lamp single-lamp energy-saving controller and control method, which is a street lamp single-lamp controller with the function of network power reduction control, and has no pollution and other adverse effects on the grid environment , At the same time, it has a strong abilit...
