PAGE 题 目： 基于GSM模块的单片机红外防盗报警系统 英文题目： Based on GSM module single-chip infrared security alarm system 二 零 一一 年 六 月 摘 要 本系统采用了热释电红外传感器以及GSM模块。热释电红外传感器具有制作简单、成本低、安装方便、防盗性能稳定等特点，它的信号易于处理并经单片机系统处理后方便和PC机通信；TC35型GSM模块自带RS232通信端口，能够方便的与单片机和PC机相连，可实现报警信号的无线快速传递，同时能直接将报警信息传送到客户手机终端上，方便及时报警，通过GSM模块也能使该系统与PC终端相连，方便多系统的协调统一管理。本设计包括硬件和软件两部分。硬件部分包括单片机控制电路、红外检测电路、报警电路、串口模块等部分组成。处理器采用51系列单片机AT89C51，整个系统是在系统软件下控制工作的。 关键词：单片机；红外传感器；GSM模块；报警电路 ABSTRACT The system uses a pyroelectric infrared sensorand GSM module. Pyroelectric infrared sensor has produced a simple, low cost, easy installation, security and stable performance. It is easy to handle and the signal processed by the MCU system and PC, to facilitate communication. Type TC35 GSM module comes with RS232 communication port and can be easily connected with the microcontroller and PC machines, enabling rapid transmission of the wireless alarm signal. At the same time alarm information can be transmitted directly to the client mobile terminal, to facilitate the timely warning. Through the GSM module also allows the system is connected with the PC terminal to facilitate the harmonization of multi-system management. The design includes both hardware and software parts. Hardware includes single chip control circuit, infrared detection circuits, alarm circuits, serial modules and other components. 51 series processor AT89C51, the whole system is under the control of the system software to work.
