随着数字技术和网络技术的发展，公共照明数字化和网络化已经成为一种必然趋势。节约能源、保证灯具寿命、提高照明管理水平、美化城市夜量和保证城市夜间出行安全等，已经成为对公共照明系统的一项基本要求。本文将介绍基于镇流器的全数字公共照明系统。该系统实现了远程单个路灯节点的任意监控，并重点介绍了系统的核心设备——组群控制器的作用、组成、工作原理是以及主要软件结构框图。
Abstract
The public lighting system widely uses the high-pressured sodium lamp or the metal halogenide lamp, the tradition lighting system uses the inductance ballast frequently, illuminates the lamps and lanterns to use the unification switch control plan.
Along with the digital technology and the networking development, the public lighting digitization and the network already became one inevitable trend.Saves the energy, the guarantee lamps and lanterns life, the enhancement illumination management level, beautifies a city night of quantity and guaranteed the city goes on a journey at night the security and so on, already became to a public lighting system basic request. This article will introduce based on the ballast entire digital public lighting system.This system in domestic has for the first time realized the long-distance single street light node willfully monitoring, and introduced with emphasis the system core equipment - - group group control regulator function, the composition, the principle of work are as well as the main software architecture diagram.1002
