The Research Of Intelligent Household Security System Based On LINUX

The intelligent household security system is a system that can detect automatically thesituation of household,when intelligent household is dangerous it alarms, so it provides muchguardance of security. The context introduces a security system of intelligent household withhigh performance and low power, which has good man-machine interactive interface and wellscalability.it works as follows：Firstly,according to the requirement of the security system, implementation plan ofintelligent household security system is designed. It constructed hardware platform based onarm,designed detection circuit of implement gas、character、entrance guard and temperature，video monitoring circuit，and GSM alarm circuit, bult software platform of Linux thehardware needed while working.Secondly, carring on the software design of intelligent household security system, itdesigned security test driver program,which fulfilled temperature acquisition and the detectionof smoke、people and state of door and window, drived GSM module to send message toalarm.After putting in use, the program is verified correct; Completed usb cameras’s videoacquisition and transmission by net; Set up a monitoring platform security system.Thirdly, for transmission quality issues of video captured by camera, it designed a videoimage processing algorithm, the algorithm applicated both the algorithm of discrete cosinetransform and the Huffman encoding to complete JPEG image compression.finally,it realizedhigh-quality compression and transmission of video images.After putting the intelligent household security system’s software and hardware togetherto debug,it finally verified the system’s reliability and stability, enabled the system to makesreal-time security detecting of intelligent household’s and remote detecting,reached thedesired effect.
