中文摘要：

针对家居中电器种类和数目繁多且分散于各室造成控制不便,提出了一种利用nRF905射频模块实现无线通信的智能家居控制系统;系统对射频数据传输协议进行了设计,给出了室内多个微控制器的组网方案;用户通过手机短信或万能遥控器把对家电的控制信号发送至基于ARM平台搭建的主控中心,再由主控中心发送至若干个通信节点或智能插座,万能遥控器通过射频信号实现对家电的近距离遥控,手机通过GSM通信实现对家电的远程遥控;通信节点基于STC89C52RC单片机设计,能够实现对多种红外家电的控制并具备安防报警功能,智能插座则用于控制非遥控家电;实验表明,该系统可使网络中各节点、插座得到有效的控制,数据传输稳定、功能丰富、可扩展性强,具备较高的应用价值.

英文摘要：

The variety and the number of household electrical appliances increase nowadays, meanwhile they disperse in many rooms. It is inconvenience to control them, in view of this, a Smart Home control system using nRF905 RF module for wireless communication is proposed. The system designs the RF data transmission protocol and gives out networking solutions of many micro controllers inside the rooms. The control signals of appliances are sent to the main control center based on ARM platform by SMS or universal remote control, then they are sent to several communication nodes or smart sockets from the main centre. Universal remote control achieves its near distance remote control by radio frequency signals, mobile phone achieves its remote control by GSM. Communication nodes are based on STC89C52RC, they can control a variety of infrared control appliances and have security alarm functions. The intelligent sockets are used to control the non remote control appliances. Experimental results show that the system enables to control the nodes and sockets in the net work effectively. The system is scalable, feature--rich and it has a high value.
