文档介绍：基于GSM短消息的远程监控报警系统
摘要:本文是提出了一种基于 GSM 短消息的远程监控报警系统,在给出系统的总体设计的基础上,设计了系统的硬件﹑软件,并对其应用领域作了一些探讨和研究。利用GSM网络作为无线智能控制报警系统的信息传输平台是一种很有效的方法,其原理相对简单,安全保密性高,网络覆盖面广,因此与传统的监控系统相比有着其相对独特的优势。
系统以 GSM 网络作为远程信号的传输平台,通过手机向设备发送特定指令的短信,设备根据短信内容进行外围部件控制。本文对 GSM 网络体系结构作了详细的讲解,并且着重讲述对于本课题相对重要的短消息业务的通信原理。数据的传输方式最主要是短消息方式,短消息的发送和接收是通过 AT 指令来实现的,本文讲述了常见的 AT 指令及其使用方法。
在系统的硬件设计中,对主要硬件 TC35i 和单片机ATMEGA8及其外围电路进行了比较详细的讲述。系统硬件包括 GSM 通信单元 TC35i,经过信息处理单元ATMEGA8 单片机,电源单元,显示单元,报警系统等。系统的软件设计主要包括单片机初始化、模块初始化、短信提取、报警电路、显示。论文的最后的部分以 GSM 短消息的远程控制系统为基础,设计出了一套基于 GSM 短消息的远程控制报警系统,并给出了此系统应用领域的一些探讨和研究。

Abstract:In this paper, a remote control system based on the GSM short message, given the overall system design based on the design of the system hardware and software and its applications made to explore and study. work as the platform of the remote signal transmission. Made on the work architecture in detail, and highlighted the plight of munication Theory of the Short Message Service is very important for this topic. Data transmission, short message, the receiving and sending of short messages through mands, about mon mands and their use.
The system hardware design, detail about the major hardware TC35一 and the ATMEGA8 microcontroller and its peripheral circuits. The system hardware consists of munication unit TC35一, the information processing unit the ATMEGA8 single-chip, power supply unit, display units, isolation control unit. System software design, including chip initialization, module initialization, SMS extraction, relay control, display. The last part of the paper-based remote control system of the GSM Short Message to design a remote control system based on the GSM short message, and gives some applications of this system to explore and study.
