| 摘要: |
| 智能家居是一个多功能的技术系统，其中智能开关控制家庭内部照明或者其它家电，是智能家居系统的一项重要技术。利用单片机可以实现开关的集中或者分布式控制、网络控制或者电话远程控制。通过AT89S52和AT89C2051将二进制数据送给MT8880变成双音多频信号传输到总线，同时MT8880接收总线上的双音多频信号并解调出二进制数据，实现了智能总线式开关，满足了智能家居系统的要求。 |

| Abstract: |
| Smart home is a multi-functionnal technological system in which the intelligent switch is designed to control the illuminating condition inside home,or some other electronic appliances,and it is an important technology in a smart-home system.Making use of MCU can help to achieve a centralized or distributed control of switches and promote the Internet control or telephone long-distance control.Through AT89S52 and AT89C2051,binary data are sent to MT8880 and then transferred to the bus as dual tone multi-frequency(DTMF) signal,simultaneously,this DTMF signal of the bus is received by MT8880 and demodulated to binary data accordingly.By this means,the intelligent bus switch control can be achieved and the requirement of smart-home system can be met. |
| Key words: smart home,bus,control switch,dual tone multifrequency(DTMF) |
