基于单片机的电子音乐门铃的设计

摘要

随着无线电技术微型电子技术的高速发展，电子门铃到现在的音乐门铃，对讲门铃、可视门铃等，其发展速度不断的提高。针对现在世界范围内经济严峻形式和我国经济发展面临新的不确定性因素，能否根据快速变化的外部经济环境来调整企业发展规划和经营方针，已经成为我国音乐门铃企业面前亟待解决的问题。无线电子音乐门铃的发展需要我们不断的进行研究、不断创新，向着产品信息化、数字化、智能化方向发展。随着人们生活水平的大幅度的不断提高，人们对自己居住环境的方便、安全提出了愈来愈高的要求，特别是家居住宅的智能化方面，人们迫切需要一种不只是使用方便、安全可靠等多方面优点于一体的智能电子音乐门铃产品，所以智能化电子音乐门铃系统的设计成为本课题研究的目标。

本文介绍了一种新式的无线电子音乐门铃，此设计采用具有编码功能的无线模块，结合单片机采用中断的方式来产生无线电方波。为电子音乐门铃两个模块之间免去连接导线、安装方便的新式电子高音质门铃。此门铃具有电路体积小，遥控距离远，抗干扰能力强，电路简单可靠，低功耗等优点，接收电路连同主控机扬声器于一体，可以轻松放置在室内有220V交流电源的地方，此设计也能够用电池供电，更加方便灵活！而且还可以播放几首不同的音乐，能够满足不同人对生活的不同需求，而且具有广阔的发展前景。

本设计采用AT89C51单片机作为主控制芯片，外部有三极管驱动播放设备，来实现优美音乐的播放的驱动，无线电模块实现无线的连接，在现实应用中更易安装，是家居首选，功耗低，遥控距离远，性能稳定等特点。

DESIGN OF ELECTRONIC MUSIC DOORBELL

BASED ON CHIP

Abstract

With the development of microelectronic technology, wireless technology, by the button doorbell began to visualdoorbell, nowthe intelligent digitaldoorbell, soaringdevelopment speed. In view of the current worldwide economic severe form andoperation of China's economy is facing new uncertainties, according to the rapidly changing external economic environment, adjust enterprise development planning and management policy, has become an urgent in front of wireless music doorbellenterprises of China's problems. In the situation of the global financial crisis, we continue to research, innovation requires the development of wireless remote control doorbell enterprise, towardthe product intelligent, digital, information-based directiondevelopment.With the rapid development of microelectronic technology, wireless technology and the network technology and the improvement of people's living standard, put forward higher request people to safety, convenient living environment, especially in theintelligent residential, people urgently need a not only safe and reliable, easy to useand other advantages of intelligent doorbell the product, so the design of wireless remote control music doorbell system has become the aim of the project.

This paper introduces a new type of wireless remote control music doorbell, it adoptssuper regeneration wireless module with encoding function, combined with SCMinterrupt generation Fang Bo, become a sound, the doorbell button and the sound source from the new remote connection, convenient installation and high quality door bell. This bell has the advantages of low power consumption, simple and reliable circuit, strong anti-interference ability, long distance remote control, has the advantages of small volume, the circuit, receiving circuit and the main controlmachine horn is equal to one, can be placed on a 220V AC power supply in indoorplaces, this design can also be powered by batteries, more convenient!
