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。

Design on public street lamp of power consumption distribution system
Abstract: Along with the developing of the house system, more and more people have bought modity apartment, the cost of street lamp was paid by the unit in the past, but the people in modity ing 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 puter 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 start button electric circuit, it can act according to the environment brightness to control whether to use the street light. Assign the device to have low consumption in power consumption of public street lamp; dependability; securities; safety, and low cost. Thus the problem of collecting stairway lamp electricity cost will be settled well.
Key words: public street lamp; power consumption distribution; puter; watchdog timer; relay interface circuit
