| With the improvement of the living standards and conditions,people are more concerned about the comfort of the living environment and the security of home. Meanwhile,the rapid development of the information technology and the popularization of the network make intelligent home technology easier and more popular.Because of its broad application value and market demand,home monitoring has become a hot technology.Based on the analysis the development of intelligent home system,we design an simple embedded intelligent home remote monitoring system through embedded system development technology.The main work contents:1.Based on studying the current situation and development trend of intelligent home system in depth,we designe the system framework of embedded intelligent home remote monitoring system.S3C2440 ARM processor and Linux operating systems as the core,combined with a sound external circuit,the system have the features of low-power,simple-controlling,cost-effective and intelligent.2.Building Embedded System Platform and Development Environment,including embedded Linux reduction and transplant,rewriting the drivers of the devices,making Linux YAFFS file system.3.USB camera is used to capture video,open source software FFmpeg is used to encode video images captured by the camera,JRTPLIB library is used in Linux development environment to transmit video through real-time streaming media programming.Meanwhile,the infrared detector is added to strengthen prewarning function.4.To achieve the objectives of the remote control,we transplant a tiny Web server to the processor,design CGI program for remote monitor and management.For more convenient function,we add Digital Temperature Gauge and lamp in the system. All the devices in the system can be remote controlled through internet.The system has the basic functions of the intelligent home,has the features of lower energy consumption,easy operation,cost-effective and good scalability,which has a wide application prospect. |
