基于三维可视化的变电站智能辅助系统应用研究

摘要

针对三维可视化变电站,文中设计了一种基于ARM+ Linux嵌入式平台的视频监控智能辅助系统,以ARM9为内核的S3C2440作为主处理器,设计音频、视频、以太网等外围接口电路.将JPEG格式图像通过TCP/IP网络协议传输到上位机,实现了远程监控功能.针对S3 C2440嵌入式系统平台特点,为实现智能监控,提出了一种背景减除法和三帧差分法的融合算法,提高了运动目标检测的准确性和智能性.最后,经Visual C++软件仿真和现场测试,可较准确、完整地提取变电站目标场景,验证了其算法的可行性,完成了对三维可视化变电站设备以及现场工作环境的实时远程监控.%In order to build a 3D visualization of substation,as S3C2240 core controller,this paper designs an intelligent assisted system based on ARM + Linux embedded platform,designs related interface circuits for audio,video,Ethernet,etc.It transferred JPEG image to host by TCP/IP protocol,realized remote monitoring.For the intelligent monitor,according to S3C2440,it purposes a target algorithm combined with three frames subtraction and background subtraction,the veracity and intellectuality have been improved.Finally,after the simulation with Visual C + + and field testing,system can get substation scene exactly and perfectly,verify the feasibility of its algorithm,and completed 3D visualization and real-time remote monitor for substation field.
