Design And Implementation Of The Security And Defense System For Home Based On The Internet Of Things

Home security has always been the focus of people attention, home security monitoring system early used spot alarm, alarm information is limited to the alarm site, however, with the advanced technology, home protection system is gradually upgraded, such as phone line and GSM network alarm can transmits the alarm information to aid department, and achieve remote alarm, this method can't meet the people for the real-time and reliable requirements for monitoring system, it can't make the public satisfied because wiring complication and high cost of maintenance upgrades and many other problem. Howerer, with the advanced technology and the emergence of the high-end products, the high technology called "Internet of Things" is developing gradually.The emerging "Internet of Things"technology seems to meet the public demand for intelligent, real-time, accurate monitoring and warning system.In this dissertation, it makes combination between internet of things technology and home defense system to promote system further intelligence. It products electronic tag for home monitoring zone in this system and assigned to the different electronic product code to distinguish the information for each zone. Home information collected by sensors in label, the system can start alarming device when the abnormal home situation, then ARM9 processor is employed as system master controller receives alarm information by nRF24L01 wireless radiofrequency chip, meanwhile ARM9 master controller transmits the alarm information to the internet by socket, remote monitoring client can only connected to the internet to receive real-time information and accurately grasp of the alarming location. To actual demand, it can create multiple remote monitoring clients to make the combination of such as the public security bureau and fire department; it provides protection for maximizing reduces the rescue time and property damage.The dissertation set up the monitoring system hardware platform and combined with software programming to achieve finally the expected monitoring system.From the platform, the processing of debug and final results can be seen that put"internet of things"technology into the home security and defense system is not only feasible, but also makes further intelligent and provides the new ideas and direction for research and development of future defense system.
