摘 要随着数字技术和网络技术地发展，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地一项基本要求.公共照明系统广泛采用高压钠灯或金属卤化物灯传统照明系统经常采用电感镇流器，本文将介绍基于PLC 地路灯控制系统.本文设计基于PLC 地路灯监控系统根据时间地变化，控制路灯地明亮程度.同时考虑到不同地季节天气等地变化地实际情况，以亮度检测控制辅助，达到更合理地目地.关键词： PLC，亮度控制，定时控制Streetlight monitoring system in the PLC - based designAbstractAlong with arithmetic figure technique with technical development in network, the public lighting arithmetic figure turn to turn to have become a kind of inevitable trend with the network. Economy energy, guarantee the lamp life span, increase illuminate to manage the level, beautify the city night measures with guarantee nighttime in city out line safety etc., have become to a basic request of the public lighting system. The extensive adoption in system in public lighting high pressure light metals turns the thing light tradition illuminates the system to usually adopt the electricity feels the town flows the machine, illuminating lamp the adoption unify switch control case. This article will introduce the street lamp control system based on PLC. In this paper, the design based on PLC street lamp monitoring system according to the time change, control the street lamp bright degree. Taking into account the different seasonal weather changes in the actual situation, to brightness detection control auxiliary, achieve more reasonable purpose.KEY WORDS: PLC BRIGHTNESS CONTROL TIMING CONTROL目录1 绪论......................................................................................... 11.1 课题背景 .........................................................
