Embedded Linux Design Home Security System Based On GPRS

Existing home security system is to provide anti-theft feature, and is not designed to fire alarms and alarm linkage function cannot form, which is a big disadvantage, this paper studied the current number of smart home and remote monitoring technology at home and abroad after the status quo and development, that the existing security surveillance systems generally use cameras to transmit video signals transmitted via the internal bus to the built-in WEB server. Users can watch in monitoring client (PC or mobile) video through a browser, but doing so is too costly, and continuous monitoring is also a waste of resources, and therefore proposed the use of GPRS for remote security monitoring, the system takes full advantage of some of GPRS advantages, such as better transmission performance, coverage is very broad, low power, and so on. Using ARM Linux as a platform, MC35i GPRS module as a communication module, a remote camera, camera, you can take advantage of the GPRS network to send MMS messages, so that photos can be sent to the user’s mobile terminal, so as to achieve the purpose of remote monitoring.The main use of the system hardware manufactured by Samsung S3C2440ARM chip as the system’s processor, temperature and smoke sensors for the home signal for effective collection and monitoring, and for comparison, judgment and analysis and recent data issued picture acquisition command, collected after the image to the user’s mobile phone and other mobile terminal sends captured through the GPRS network site pictures and some of the warnings, the realization of the home situation, real-time monitoring, so that you can effectively reduce the system requirements and system load, but also can save money, but also reduces the network capacity requirements, making the feasibility of using GPRS data transmission network to get better, in terms of software including embedded Linux cutting and transplantation, each module Implementation and through the GPRS network module sends a warning message to the user and pictures. After testing proved that the basic realization of the remote monitoring system functions to achieve the desired results, the feasibility is relatively high, the feasibility of the system has a high, low cost, small size, easy to operate, has a relatively good prospects for development.
