基于GSM通信的智能家居报警系统
摘要
随着GSM网络的迅速普及移动通信技术的飞速发展，将GSM技术运用于实现家庭智能报警具有实际应用价值。
本系统采用STC89C54RD+单片机为核心控制器，由GSM模块、传感器数据信息采集模块和报警模块组成。根据家居中可能发生的各种情况选择合适的传感器，例如：温度传感器、红外传感器、气体传感器。其中温度传感器用于采集家庭的温度信息，当家庭温度超过指定温度时，单片机将进行温度报警信息的发送；红外传感器可以检测是否有人闯入房屋，如有入侵者经过发光管和接收管中间，电路将处于触发状态；气体传感器用于对煤气、天然气的测量。传感器采集的相关报警信号通过GSM短信模块，借助GSM移动网络，以短消息形式直接把家里情况反映到主人手机屏幕上。
该系统具有安全保密性高，又不需要组建专用网络和维护网络，网络覆盖面广，因此与传统的监控系统相比有着其独特的优势。

Abstract
With GSM network the rapid popularization of mobile communication technology rapid development, will GSM technology applied to realize intelligent alarm have family practical application value.
The system uses the STC89C54RD + monolithic processor controller, the GSM module, sensor data information acquisition module and alarm module. According to the household to happen in all kinds of selecting suitable sensors, for example: the temperature sensor, infrared sensors, gas sensor. Among them, the temperature sensor used in the temperature of the family gathering information, when temperature more than specified temperature family, single chip microcomputer temperature alarm will send the information; Infrared sensor can check whether someone broke into houses, such as invaders light tube and receiving through the middle, circuit will be state trigger; Gas sensor for coal gas, natural gas measurement. Sensors to collect relevant alarm signal through the GSM message module, with the aid of GSM mobile network, with the short message form directly to the home situation reflects on the phone's screen to the master.
The system has the high security secrecy, and don't need a special network and maintenance of the network, the network coverage, so with the traditional monitoring system has its unique advantages compared.
