Wireless Cdma Network-based Intelligent Monitoring System Design

With the rapid development of technology and human safety consciousnessenhancement, surveillance system becomes more and more popular in recentapplication. How to improve the capability of surveillance system is one of the mostimportant problem. After summing up the defects of traditional surveillance system,this thesis analyzes the advantage of new wireless intelligent surveillance system.According to the characteristics of the C/S model and the B/S model respectively,this thesis presents a mixed arthitecture of the embedded wireless and intelligentsurveillance system. This system is based on the combination of CDMA20001×wireless network and embedded Blackfin BF533 system. It integrate the technology ofimages compression, motion detection and human recognition.The system canautomatically detect moving object, send alarm SMS, link system server andtransmit data with CDMA network.The wireless intelligent surveillance system choose codebook algorithm andvoting model for human motion detection. This thesis ameliorates the codebookmodel which coquer the changing environment and enhance the robustnessperformance of the system. This system is designed by double-thread arthitecture.DMA, Cache and optimization techniques enhancethe real time performance of thesystem.The result of experiment demonstrates this systemic designs achive theperformance requirements satisfactorily.
