毕业设计说明书公用路灯用电量分配系统的设计专业电子信息工程学生姓名王 乾班级BMZ 电子 082学号0861407225指导教师曹 妍完成日期2012 年 5 月 31 日公用路灯用电量分配系统的设计摘 要：随着住房制度改革的深入，越来越多的居民买了商品房，原来的单位住宅楼的公用路灯费用是由单位出资的，而商品住宅楼内的居民来自不同的单位，要不要安装路灯？安装路灯后费用如何解决？“公用路灯用电量分配系统”是为了解决商品住宅楼内公用路灯的收缴费用问题。系统的设计包括硬件部分和软件部分的设计，硬件部分主要功能模块由单片机芯片 AT89C2051，复位及看门狗电路 MAX813L，继电器接口电路，数码管显示电路等组成。系统以 AT89C2051 单片机为核心，利用其指令来实现对住宅公用路灯用电量的自动分配。介绍了软件编程思想及设计中应考虑和解决的几个主要问题。公用路灯用电量分配系统具有低功耗、可靠性、安全性、低成本等特点。设计解决了楼道路灯电费收缴的难题，有较好的实用价值。关键词：公用路灯；用电量分配；单片机；看门狗；继电器电路Design on public street lamp of power consumption distribution systemAbstract: Along with the developing of the house system, more and more people have bought the commodity apartment, the cost of street lamp was paid by the unit in the past, but the people in the commodity are coming from different places. Do they need the street lamp and how to pay the cost for everyone? " Public street lamp of power consumption distribution system", can solve all of them. The design includes the systematic hardware block diagram structure, some main function module (the AT89C2051 microcomputer and watchdog timer MAX813L, relay interface circuit, etc.) and unit circuit, the software programming thought and the problems in the designing. The system takes AT89C2051 monolithic integrated circuit as a key, using its instruction to get the public street lamp of power consumption of automatic assignment. And with the illuminated examination system in the street light ...
