无线音乐门铃的设计与制作院系:信息工程学院姓名:学号:专业:通信工程年级:0801指导教师:职称:副教授完成日期:2012年5月摘要随着微电子技术、无线技术和网络技术的飞速发展以及人们生活水平的大幅度提高,人们对居住环境的安全、方便也有了越来越多以及越来越高的要求,主要体现在智能化住宅中,人们着眼于一种安全可靠、使用方便等优点于一体的智能化门铃产品,因此无线遥控音乐门铃系统的设计成为本课题研究的目标。本文介绍了一种新型无线遥控音乐门铃,它采用具有编码功能的遥控发射-接收专用集成电路结合高音质机电式音乐门铃做声源,成为一种声音动听
2、、门铃按钮与声源之间免去连线、安装方便的新型遥控高音质门铃.这种门铃具有功耗低,电路简单可靠,抗干扰能力强,遥控距离远,电路体积小等优点,其接收电路连同机电式音乐门铃为一体,可以随意放置在室内的某个地方,还可变换各种门铃音乐,使声音悦耳动听,满足不同人群的生活需要,具有广阔的发展前景。该无线音乐门铃用PT2262/PT2272集成芯片作为发射和接收主电路,本设计选用宏晶公司高性能单片机STC89C52,该芯片为52内核8位单片机,兼容Intel等52内核单片机,支持ISP下载,适用于常用检测控制电路具有性能稳定、功耗低等特点。关键词:无线遥控;PT2262
