摘要：随着中国经济的快速发展，人类对电力能源的需求日益增大，电力资源日益缺乏。因此如何节能降耗已成为近几年来人们关注讨论和研究的话题。

本文研究的路灯控制系统是针对我国城市在路灯照明的控制方面产生的巨大能源消耗和浪费而开发出的新的智能型的路灯控制系统。本文详细介绍了该系统的设计与实现。本文详细介绍并分析了以GPRS技术、电力载波技术、单片机芯片AT89S52、光敏传感器为主要部件的硬件电路。通过时间控制和环境参数控制相结合的方法去控制路灯。实现随着光照强度的大小和在一定时间段内路灯都有着的不同表现，午夜路灯间隔开以节省电源，光照很足时路灯全部自动断开不工作等功能。

该路灯控制系统是一种智能型控制系统，电力资源既能够得到合理利用。随着社会的发展，路灯控制系统会得到更广泛的应用，具有非常光明的前景。 关键词:GPRS、PLC、单片机、光敏传感器

Abstract: With China's rapid economic development, human power energy demand increases day by day, the power increasing scarcity of resources. So how to saving energy and reducing consumption has become in recent years people pay more attention to the discussion and the research topic.

This paper studies the street lamp control system is in view of our country city in street lighting control enormous energy consumption and waste and to develop a new type of intelligent lighting control system. This paper introduces the system design and implementation. This paper introduced and analyzed with GPRS technology, PLCtechnology, the single chip AT89S52, photosensitive sensor for the main components of the hardware circuit. By the time control and environmental parameters control combination method to control the street lamp. Achieve with the light intensity of the size and within a certain period of time lights have different manifestations, midnight lamps spaced to save power, illumination is enough when the street lights automatically disconnect function does not work.

The street lamp control system is a kind of intelligent control system, electric power resources to rational use. With the development of society, street lamp control system will be more widely used, has a very bright future.

Key words: GPRS、PLC、single chip、Photosensitive sensor
