文档介绍：基于GPRS实现远距离家庭监控系统设计
摘要
随着社会经济高速发展和人们生活水平的不断提高,人们的物质生活与精神生活需求也变得多样化,人们更希望在一种安全、舒适的环境下生活,于是家庭的安防需求应运而生,使得智能监控报警系统与居民日常生活越来越紧密,以保障家庭住宅安全为目的的防范系统,也因此得到了一定程度的发展。经查阅相关领域的资料文献,发现目前的家庭安防系统大多数存在着功能简单,易遭破坏,报警准确度太低等问题。随着家庭安防的发展需求,能满足用户需求,性能可靠,经济实用的监控报警系统具有广阔的发展前景。
本文以GPRS通信理论为依托,采用彩信图像传输技术,设计了基于ARM7内核和GPRS实现彩信家庭监控报警的系统。它将采集的入侵图像以彩信的形式发送到用户手机终端,达到了及时准确的传送。系统监视终端采用最新的ARM7内核的低功耗微处理器LPC2210作为核心处理器,用热释电红外传感器和BISS0001信号处理电路设计了入侵检测模块,采用内部集成JPEG图像压缩功能的GXT-M201摄像头模块完成入侵照片的采集功能,用NAND FLASH芯片设计了图像储存模块,采用具有彩信功能且内嵌TCP/IP协议栈的GPRS模块TR800作为数据发送模块,整个监视终端主要实现了入侵人员的检测、现场图像数据的采集和存储以及无线网络传输等功能。接收终端只需要用户具备一部支持彩信功能的手机即可。整个系统除了保证正常的工作外,还可以接收来自用户的短消息命令,系统识别并响应指令,从而完成用户的主动请求,达到远程控制的目的。
与以往的监控报警系统相比,该系统将彩信图像传输技术,红外光电传感器技术,无线信号传输技术相结合,利用GPRS网络技术,提高了报警的准确度,增强了用户的主动性,降低了成本,在家庭安防领域具有很强的竞争优势,能够产生良好的社会效益和经济效益。

Design of Remote Home Monitoring System based on GPRS
Abstract
With the development of social economic and the improvement of living environment,people’s demand on the security of their own home is increasing,which makes home security and the lives of people connect strong support of the rapid development of munication technology,the filed of home security has been the rapid the investigation of information,we found today’s security systems are not suitable for home use because they plex for operating,not convenient for plicated for wiring that affect the indoor have pressing requirements for relatively low price and power consumption and monitoring and alarm system of reliable technical design of practical security product that is used in the home and small office have the realistic meaning and practical value.
This article has designed take the GPRS correspondence theory as a backing,uses the MMS technology and based on my schoolmate of hardware designs of infrared wireless alarm system based on terminal of system use the latest low power microprocessor LPC2210 based on ARM7 core as core process
