摘 要
该设计是采用STC89C52单片机实现的基于GSM网络SMS短消息功能的家庭防火报警系统。该系统主要由单片机STC89C52、TC35模块、DS18B20温度传感器、蜂鸣器报警器、数码显示管，其它基本外围电路组成。借助最可靠、最成熟的GSM移动网络，以最直观的短消息，直接把报警地点的情况反映到所设定的手机屏幕上。
该系统通过传感器检测家庭安全隐患，把检测结果送入单片机，通过单片机控制GSM Modem向预先设定好的手机号码发送报警信号。同时配备蜂鸣报警器发出警报声，以及数码显示管显示现场当前的温度。
该设计融合了通信技术、计算机技术、测试技术、家庭安防技术等多个学科。是一个涉及电子、通信、计算机软硬件的综合应用系统。设计的系统运行稳定，性能良好，具有一定的应用前景。

Abstract
The design using MCU STC89C52 is a family fire alarm system which is based on the GSM network SMS messaging function. The system mainly consists of MCU STC89C52, module of TC35, DS18B20 temperature sensor, buzzer alarm, digital display tubes and other basic peripheral circuit. With the most reliable, most mature GSM mobile network and the most intuitive message, it reflects the situation of the alarm location to set on the phone screen directly.
The system detects the home security risks through sensor, puts the test results into the MCU and controls the GSM Modem through the MCU to send alarm signals to the predefined phone number. At the same time, it is equipped with a buzzer alarm warning sound, and digital display tube displays current temperature.
The design combines communications technology, computer technology, testing technology, home security technology disciplines involved in electronics, and it is a comprehensive applications system which involve communications, computer hardware and software, the design of the system is running stable, good performance and with a certain application prospects .
