| As long as the development of technology and the growth of living standard,the security consciousness of people became higher and higher and the claim ofhome security has been heightening continuously. In recent years, wirelesscommunication, embedded technology and network technology are changing theworld and our life, so intelligent life and intelligent society have been acceptedgradually by the public.“Intelligent home†will become the popular trend infuture. However, there are a lot of shortcomings on traditional intelligent home,such as the complex wiring, not easy to change and e xpend; no fixedcommunication interface standards; rely on PC, poor immediacy, not easy toupgrade and maintenance.This paper designs the system takes Android mobile phone as client end,adopts the latest ARM11microprocessor, integrated Linux operation s ystem,USB camera, temperature test module, smoke detection module as well asinfrared sensor module to collect inside information, and execute the alarm touser’s mobile phone by E17503G module. The system will send alarminformation messages to user automatically when the temperature and smokeconcentration exceeds the set threshold or a thief invasion. The system alsoapplies dynamic WEB technology, the network communication technology basedon RTP/RTCP real-time communication protocol and3G wireless communicationand transmission technology, so that the users can obtain current temperature andsmoke concentration at home, also can transfer the information of video andmake remote control with Android mobile phone or computer.The software design the Android mobile phone application， from twoaspects of the server and client design train of thought and communicationmechanis m are introduced. There are various modules of the application, such as temperature acquisition program, smoke collection procedures, intrusiondetection program,3G information sending and receiving procedures, videocollection procedures, video encoding program, video transmission program. Aswell as to make WEB server, the supervision system log-in page and develop therespective CGI interface.This paper designs an intelligent home security system characterized withpracticality, convenience and expandability, it has very important significanceand application value to the alarm function on fire detection and outsiderinvasion, and maintain the security of family life, whose module designfacilitates the system maintenance and make the excellent foundation for thefuture system improvement. |
