文档介绍：基于GSM远程安防系统设计
摘要
随着人们生活水平的提高,人们的安防意识也有了相应的提升。传统的安防系统已经跟不上快速发展的社会步伐,社会需要新的、更为可靠的、适用于大众的安防系统。
本文将目前世界上应用广泛的全球移动通讯系统即GSM(Global System for munications)应用到安防系统中,一改传统的有线方式,使整个安防系统更加完善、更加现代化。
本设计主要由STC89C52RC单片机和GSM MODEM组成,借助最可靠、最成熟的GSM移动网络,以最直观的中文短消息或电话形式,直接把报警地点的情况反映到用户的手机屏幕上,用户可以通过电话或短信息来回发控制信号。
设计中介绍了单片机、GSM、传感器的基础知识,同时设计出了相关的各部分电路原理图以及软件流程,软、硬件相结合,详细介绍了整个系统。

Abstract
As people's living standards improve, people's sense of security has also been a corresponding increase. Traditional security systems have not keep up with the rapid development pace of the society, society needs a new, more reliable and applicable to the public security system.
This article applies GSM (Global System for munications) which is widely used in the world at present to the security system, aiming at changing the traditional wired security system so that the whole security system more perfect, more modern.
This design posed by the STC89C52RC microcontroller and GSM MODEM, with the most reliable and most mature GSM works in the most intuitive form of Chinese short messages or phone directly to the alarm location is reflected to the user's cell phone screen, users can telephone or text messages back and forth hair control signal.
In this design, Single-chip puter, GSM, basic knowledge of the sensor were introduced, and the various parts of the circuit schematic as well as software processes were designed, software and bination described in detail the entire system.
Key words: Single-chip puter; GSM; Sensor
