基于51单片机的智能路灯控制器的设计与实现毕设论文_精品.doc

摘 要 现在，随着微电子技术和集成电路技术的快速发展，单片机技术无处不在。单片机作为计算机科学与技术的重要组成部分，作为嵌入式系统的先头兵，片上系统的先行者，已经被广泛运用到了各行各业，尤其是与控制相关的领域，极大地提高了产品的智能化程度和技术水平，已经成为了当今社会十分重要的技术领域。随着社会需求和单片机应用领域的不断扩展，各类智能产品、控制系统都是以单片机技术为核心来进行开发设计的。 本系统采用MSC-51系列单片机1和设计灯控制器，实现了能根据实际通过801芯片的P1口的功能随着社会文明的不断发展，城市照明已不仅局限于街道的照明，而且发展成了了城市景观等装饰性照明的综合市政工程。 ABSTRACT Nowadays, with the rapid development of micro-electronic technology and integrated circuit technology , Single Chip Micro-computer (MCU) technology is being used everywhere . MCU has been used in all kinds of industries, especially in the areas concerning the controlling as the important ingredient in the computer science and technology , the front-runner in the embedded system. It has improved products’ Intellectualized and technical standards and been a quite important technical area in our recent society. With social needs and the applied areas of MCU expanding , types of mental products and control systems are designed with MCU as the central technology. The system uses MSC MCU -51 and Relevant photo electric equipment to design intelligentized controller of streets lights and realize the function of controlling the switches according to the actual conditions of light through P1 port of 8051 chip. As the ever-accelerated development of social civilization, City light is not only confined to the street lighting but also developed into the urban landscape and decorative engineering project.
