基于GPRS的智能家居安全监控

摘要

In order to monitor living-room for safety, the living-room images are necessary to be obtained. The living-room images are collected through the embedded network instrument based on uClinux operation system. The remote image communication system through General Packet Radio Service (GPRS) and Internet was completed. The network instrument is composed of MCF5272 and the uClinux operation system, which is linked to Internet through GPRS. The image was stored and transmitted in files after decode and encode.The structure of network instrument for collection image, the system of remote image communication, the design of automatic transmitting for image files in embedded system and receiver were introduced in the paper. The experiment of remote image communication with the embedded network instrument was realized and tested. The result is that the network instrument can be used for living-room intelligent monitoring to prevent from theft.%为了掌握智能家居的安全性,需要监测家居的图像信息;采用嵌入式系统获取家居的监测图像,通过GPRS无线远程通信和Intemet传输,实现了基于uClinux嵌入式操作系统的图像采集网络仪器和通过GPRS传输的家居远程图像通信系统;网络仪器以MCF5272为硬件核心,以uClinux为操作系统,采用GPRS方式实现远程接入Internet;图像经过解码和编码后,以文件方式保存和传输;介绍了图像采集网络仪器的构成、GPRS远程家居图像通信系统的组成、接人Internet的uClinux方式、嵌入式中图像文件自动传输与接收设计,并通过实验检验了网络仪器和家居远程通信的实现方案;结果表明,通过GPRS和网络仪器,可以实现家居的安全监控,从而保护家居的财产安全.
