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.
