本设计针对现有的GSM无线网络，介绍了基于GSM的远程家庭智能报警系统的设计及实现方法。利用各种传感器，如温湿度传感器、加速度传感器等对家中可能出现的各种意外情况进行采集，并通过组建的家中内部无线网络及时向单片机进行中断报警。GSM模块在单片机控制下，利用GSM网络，将各种报警信息通过短信的方式发送到预先设定的手机中，达到了远程无线智能报警的功能。同时,本文在对加速度信号的处理上,采用新的方法,即使用加速度平均值,并设定参考点的思路和方法,有效避免了漏报、误报现象的产生，是系统更加稳定。(Aiming at the existing GSM wireless network, this paper introduces the design and implementation method of GSM based remote home intelligence alarm system. Various kinds of sensors, such as temperature and humidity sensors and accelerometers, are used to collect all kinds of accidents that may occur at home, and the interruption alarm is carried out to the single chip computer in time through the internal wireless network in the home. The GSM module, under the control of single chip microcomputer, uses GSM network to send all kinds of alarm information to the pre set mobile phone by short message, so as to achieve the function of remote wireless intelligent alarm. At the same time, in the process of acceleration signal processing, this paper uses a new method, that is, the use of the average acceleration and the idea and method of setting the reference point, effectively avoiding the phenomenon of misreporting and misreporting, and the system is more stable.)
