文档介绍：摘要
随着GSN网络的迅速普及移动通信技术的飞速发展,新技术和新业务的开发和应用已提到十分重要的位置。将GSM技术运用于实现家庭智能报警具有实际应用价值。
该系统以单片机AT89S52为核心作为控制模块,由GSM无线通信模块、传感器数据信息采集模块、液晶显示模块和报警模块组成。通过传感器模块中光电传感器和温度传感器采集相关信号,经A/D转换模块转换成单片机可处理的数字信号,经过语音报警模块发出相关报警信号,将该信号通过GSM短信模块,借助GSM移动网络,以中文短消息,直接把报警地点的情况反映到您的手机屏幕上。
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 the rapid popularization of works and the fast development of munication technology, new technologies and services have been stepped up to an all-important position . GSM technology will be applied to achieve practical application of intelligent alarm home value.
The system is MCU AT89S52 the core as a control module, which is consist of the GSM munication module, sensor data acquisition module, LCD module and alarm module. Photoelectric sensor module through the sensor and temperature sensor acquisition-related signals,through the A / D converter module into digital signals which a single chip can handle, after issuing the relevant alarm voice alarm module signals,the signal is through the GSM SMS module,with GSM work, through Chinese short message, directly to the alarm location is reflected to your mobile phone screen.
The theory is very simple and has high security, and there is no need to set up works and to maintain them, moreover the area of works covering is very wide, so this method has many particular advantages over conventional monitoring system.
