Design Of Intelligent Home Security Monitoring System

After entering the twenty-first Century,with the rapid development of the Internet and mobile networks,all walks of life are in the direction of networking and intelligent development.A variety of intelligent devices appear constantly,and greatly facilitate people's life.However,in these intelligent devices,smart phones are undoubtedly the most popular.The emergence of smart phones has impacted the traditional home security industry,thus promoted the development and application of intelligent monitoring of mobile terminals.While smartphones continue to update and improve chip computing capabilities,the decode library of mobile video also adds a number of new members and began to support standard H.264 video.At present,in the industry of home security monitoring,most monitoring systems are cross platform development,that is to say,monitoring acquisition system and mobile client are developed by different platforms,which involve the platform compatibility issues.And processing is also more cumbersome.At present,many monitoring systems only provide monitoring without early intelligent detection,early warning,remote voice propaganda and other functions.Based on the above,a smart home security monitoring system based on Android is designed,which includes three parts:monitoring acquisition system,SRS server and mobile video monitoring client.Intelligent monitoring system based on ARM A9 burns Android system on embedded devices,and expands USB camera,infrared detection and door magnetic detection to collecte the corresponding video information and sensor signals,which specifically includes:using the mature H.264 standard to encode video,using RTMP protocol to transmit video,designing a double alarm mode combining mail and SMS and writing the device driver of infrared detection and magnetic detection.The SRS server is built on the Ubuntu system to provide a carrier for monitoring video transmission.The video monitoring client transplants h.264 video decoding library,and uses RTMP protocol to obtain the audio and video streams transmitted from the server,and realizes the real-time playback of mobile phone client.When receiving the alarm information,users can check the home security situation by logging on to the mobile video monitoring client and take corresponding measures.The test results of the intelligent home security monitoring system show that the monitoring video with resolution of 640*480 and the frame rate of 30 frames/sec can be obtained on the Android client.The capture and reception of video is clear and real-time.The system can find burglary and make early warning and warning about theft,which meets the basic requirements of the security of the family security and provides a reference for the intellectualization and industrialization of the family security.
