毕 业 设 计 设计题目：智能温度报警系统设计 ——烧水器的温度控制报警设计 系 部： 电子信息工程系 专业名称： 电子信息工程技术 班 级： 08432 学 号： 38 姓 名： 茆 红 芳 指导教师： 郑 莹 完成时间： 2011 年 5 月 12 日 智能温度报警系统的设计 摘要 我的设计是烧水器报警系统的设计，功能是温度超过上限值或低于下限值时发出声光报警信号，来提醒人们采取措施,同时烧水器断开。采用热敏电阻来采集温度，用一块施密特集成电路CD4093来对电路进行控制，反应灵敏且声光同时显示，用三极管作开关控制烧水器，整机元件少、功耗也低。 关键字 温度报警、敏感元件、CD4093、压电陶瓷、三极管 Intelligent temperature alarm system design AbstractBoil water device alarm system design is the upper or lower than temperature exceeds a lower sound-light alarm signal, to remind people take measures, to boil water implement disconnect. Its alarm system is used to collect the NTC thermistor temperature with a schmidt integrated circuit, control circuit CD4093 to, senstive respond and acousto-optic shows at the same time, the machine components, less power consumption is low also. My design is the design of water implement alarm system, function is temperature over the upper or lower than a lower sound-light alarm signal, to remind people take measures, to boil water implement disconnect. Using thermistors to collection temperature, use a schmidt integrated circuit CD4093 to circuit control, senstive reaction and acousto-optic shows at the same time, use triode be switch control is less component, the water, power consumption is low also.My design is the design of water implement alarm system, function is temperature over the upper or lower than a lower sound-light alarm signal, to remind people take measures, to boil water implement disconnect.
