1、2011年度学生科研立项结题申报书作品名称：可控温电热壶作者姓名：张建伟、贾明泽学　　院：信息与电气工程学院班　　级：电气工程及其自动化09-2联系电话：13964883149指导教师：张仁彦作品类别：□自然科学类学术论文□哲学社会科学类社会调查报告和学术论文科技发明制作□其它二○一一年十一月41可控温电热壶（作品名称）摘要：本作品为可控温电热壶，所完成的主要功能为：1．温度模块：实时温度检测、采集、传输与显示。2．时间模块：利用实时时钟芯片，编程实现时间计时，并送至数码管进行动态显示。3．闹钟与温度报警模

2、块：通过独立按键实现快速设置当前时间、闹钟时间、报警温度，并通过循环检测实现闹钟与温度报警提醒，温度高于报警值时自动断开电源，低于报警值时接通电源，实现温度的准确控制。4．掉电保存模块：实现数据掉电自动保存，通电自动恢复的功能。41目录第一章概述······················································31.1目的意义及国内外同类研究的动态······························31.2课题主要内容及技术指标···············

8、设计中特别考虑到这一点，通过在STC89C52单片机的支路上设置开关，从而实现单片机与PCF8563的分别供电，从而避免了在不使用电热壶时数码管显示所造成的能源损耗，减少了经济支出。而在PCF8563中纽扣电池的加入保存了设置数值，避免了重新上电后数据的丢失，减少了用户反复设置的苦恼。国内外同类的研究动态：目前，国内已有类似方向的研究（专利号：200820012742），而且实际生产中也有此类产品问世，但是结构多
