The Design And Implementation Of Monitoring-Center Software In Video Monitoring System

In recent years, with the integration of the computer, network and multimedia technology, the embedded digital video monitoring technique has become a development trend of surveillance field. So, the research on the design of the software in the embedded digital video monitoring system has great social and economic significance.In this thesis, based on a practical embedded digital video monitoring project, we briefly introduce the whole framework and each part of the system, focus on some key technologies used in the server software, and detailedly describe the design and implementation of the server system.This monitoring system is mainly made up of monitoring-center, the client and the video server. This thesis firstly briefly introduces each part of the whole system, puts emphasis on the basic design ideas including using agency and object-oriented, and particularly analyze the subsystem partition of monitoring-center.Then, the thesis detailedly describes some key technologies used during the realization of monitoring-center. These key technologies include communication theory of the server and the client based on TCP/IP protocols, sockets programming, multithreading and ADO. It mainly discusses sockets programming flow and how a top application can access to the database through ADO.Based on agent and object-oriented design, the next focus of this paper analyzes the interdependence between subsystems, followed on the subsystem architecture and implementation. It focuses on the system's data structure and detailed describes the database design and implementation.
