摘要
随着社会的发展和科技的进步,越来越多的家用电器进入了人们的生活,这些家用电器给人们的生活带来了很多的方便和享受,同时随着电话在家庭的普及,电话机的功能将进一步得到开发和利用。利用电话实现家用电器遥控是家电未来的发展方向之一。
本次毕业设计的题目是用AT89C51实现电话远程控制家用电器,该系统主要是由AT89C51单片机、DTMF解码芯片MT8870、语音芯片ISD2560和存储芯片24C02组成。可以用电话机或手机在任何地方、任何时刻通过此系统来远程控制家里的电器。该系统可以直接开关电器、延时开关电器、监听家中声音、密码修改和存储及其状态查询,并且有自动语音提示功能。
系统具有运行可靠、成本低、操作方便、适用性强等特点,可以广泛应用于城市社区,具有较大的推广价值。
关键词:单片机,电话,远程遥控,语音提示
ABSTRACT
With the development of scientific technology,an increasing number of home appliances e into people's daily lives. These home appliances have brought in much convenience and enjoyment to people's life. The function of telephones will be further utilized and developed along with the popularization of telephones. Home appliances will probably be controlled by the telephone using the remote control technique in the future.
The thesis of graduation designer is a remote-control system of home applicances, it is based on AT89C51 MCU with a system is mainly consisted of the AT89C51, DTMF decoder chip MT8870, Voice chip ISD2560 and memory chip 24C02. The telephone or the cell phone can be used at any place, any time through a intelligent telephone remote control system to control home appliances. This system has a function to turn on the home applicances directly,or turn on the home applicances in a defintly time. Wiretapping , changing and storing passwords and inquirying the state of home applicances.
In fact, the system showed its great advantages in the practical application, such as a high reliability and applicability but a low cost and easy operations. Therefore, the device could be applied munite in the city and its well worth doing so.
