The Research And Design Of Embedded Wireless Intelligent Security Monitoring System Based On ARM9

With the rapid improvement of technology and life, people take care the security of housing much more than in past, so the products of housing security was in favour of people. Meanwhile, people have much high expectation of housing-security products,and smart-housing monitor will be the trend in development of housing security.This paper demonstrates the design of wireless smart security system based on the ARM 9, and the design was on the basis of modern smart security system and targeted embodied monitoring system and facing to the low smart level and incomplete functionality of developed products. The system posses the advantage of the high level of smart, complete function, convenience and high performance, which consists of the model of imaging, fault detection, emergency, identification and alarm. The imaging and fault detection model play a role of execute control which detect the situation of inbreak or not,and the alarm model would sent an SMS message to the pre-set cellphone number; the identification model was used to identify the owner in house or not. If the owner is in house or not, the smart security sysemt is at work or not.This paper applied the differential algorithm to upgrade the signal-to-noise ratio and efficiency of imaging, and designed the algorithm of self-adaptive division and proximtiy detection for promoting the efficiency.The test results demonstrated that this system has the advantages of brief strcture, smart, convinienct and extensive and can server to the security of housing, so achieve the expected target.
