基于单片机的太阳能热水器控制系统的设计与实现 大学毕设论文.doc

-I- 摘要随着全球人口和经济规模的不断增长,能源使用带来的环境问题及其诱因逐渐为人们所认识,“低碳经济”这一概念开始进入人们的视野。太阳能具有储量的“无限性”、存在的普遍性,并且几乎不产生任何污染。鉴于此,人们在大力的发展太阳能产业。太阳能热水器顺应时代发展的要求,满足人们对环保绿色产品的需求。在人类文明程度日益提高的今天,它是现代文明社会的最佳选择。本文提出了一种新型的太阳能热水器控制系统设计方案。本设计采用 MSC-51 系列单片机 AT89S52 作为中央处理器,采用 DS1302 实时时钟, 12864 点阵式液晶显示屏等模块,完成时间温度水位的显示,以及时间和温度的设定等功能。关键词: 太阳能热水器;单片机;实时时钟;液晶显示屏- II- ABSTRACT As the global population and economic growth, energy use of environmental problems and causes gradually recognized, "low-carbon economy," the concept became part of the people of vision. Solar energy has reserves of the limitless ", the universality of existing, and almost does not produce any pollution. In view of this, people in the development of solar energy industry. Solar water heaters, in conformity with the requirements of the times, are meeting the demand for green products. In human civilization increasingly today, it isa modern civilized society. A new solar water heater control system design. This design incorporates MSC-51 MCU AT89S52 as central processors, a real-time clock using DS1302, 12864, dot-matrix LCD module, completion time display of the temperature level, as well as the time and temperature setting.
