基于ZigBee和ARM的嵌入式智能家庭安防系统设计

Design of Embedded Intelligent Home Security System Based on ZigBee and ARM

在现代家居安防系统设计中,采用ZigBee和ARM相结合,传感器输出的信号经过处理由支持ZigBee协议的CC2430收发模块传输至主机S3C2410,实现前端信号与后端控制器之间的无线连接;主机根据节点情况判断家中有突发事件后,通过GSM/GPRS模块短消息通知主人或者物管中心,同时发出声光报警,并驱动摄像头抓拍现场图像,从而构成嵌入式的智能家庭安防系统.系统用以太网接入小区的局域网或互联网,实现家庭网络Internet接入,采用ZigBee和ARM9内核的处理器及μc/osII操作系统.与现有的安防系统相比,具有方便灵活及移植性好等特点.

In the design of modern home security system, this paper combines ZigBee with ARM. The pro- cessed sensors＇ output signals are transferred to the host S3C2410 by CC2430 transceiver module which is supported by the ZigBee protocol; and it achieves the wireless connection between the front-end signals and back-end controller. According to the nodes＇ signals, the host determines family emergencies, and informs the owner or property management center through the GSM / GPRS module SMS. At the same time, the host drives the camera to capture images at the scene, and issues a warning by sound and light. This con- stitutes an embedded intelligent home security system. The system connects the Internet using Ethernet LAN, and it uses ZigBee and the processor based ARM9 core and μc/osⅡ operating system, so it has the characteristics of convenience, flexibility and portability compared with the existing home security systems.
