Unfortunately, portability brought another question is stolen goods are very easily. The traditional method is mainly to guard against theft of mechanical anti-theft lock, anti-theft lock this a very heavy, and the equipment is also removed trouble, so affected items of portability. So embedded security system as our main research direction. The system USES the production of GTM900 by huawei-C module, use the wireless send and receive, baseband processing function, to realize the wireless data transmission and text message to send and receive tasks. The system vibration acceleration sensor has easy fabrication, low cost, easy installation, security and stable performance, etc, the external power supply way, it is easy to deal with the signal and SCM system treatment convenient and PC communications. Can realize alarm signal wireless rapid transfer, and at the same time can directly will alarm information sent to customers mobile phone terminal, convenient timely alarm, through the GPRS module can also make the system and PC terminal connected, more convenient to the harmonious and unified management system. GTM900-C use wireless send and receive, baseband processing function, to realize the wireless data transmission and text message to send and receive tasks. Combined with AT89C51 single-chip microcomputer, plus
