视频监控系统由实时控制系统、监视系统及管理信息系统组成。实时控制系统完成实时数据采集处理、存储、反馈的功能；监视系统完成对各个监控点的全天候的监视，能在多操作控制点上切换多路图像；管理信息系统完成各类所需信息的采集、接收、传输、加工、处理，是整个系统的控制核心。论文分析了一种基于VB技术的网络视频监控系统。将usb摄像头采集来的图像数据压缩后，经过网络传输，完成对监控现场的网络视频监控任务。论文首先阐述了网络视频的监控系统的发展状况，分析了主要外围电路的设计，以及如何在VB平台上进行程序的编译与移植，并对在windows操作系统下的USB驱动程序进行了研究。最后以提供的例子进行了系统整体测试并提出了进一步开发设想。

The Railway Compartment of Video Surveillance System
Abstract:The video frequency supervision system ability at the situation that person can't observe directly, well timed, portrait, really reflect to be keep watch on appearance of control the object.The video frequency supervision system has become the most valid observation tool supervise and control in modern management.The video frequency supervision system is a kind of total amount word turn, the whole network turn of system, can the together existing multi-media system, the control system and the information systems gather, carrying out the share of the data and information in the control centre expediently, the operation of only a staff member, can observe manies to is control district, and long-distance leave the supervision function of the district.
Video frequency supervision system from solid the hour controls the system, surveillance system and management the information system constitute. The solid hour controls the data for system to complete solid to collect the processing, saving, the function of the feedback,keep watch on the system completes the all-weather surveillance that orders to the each supervision, the ability is operating control point more up cut over many road pictures,Manage the information system completes each kind of to need the information to collect, receive, transmit, process, handle, is the whole control core of system.The construction of video surveillance system is put forward and discussed . The driver of USB device is researched ,under Windows operating system is studied , and then the transplantation of data on the VB platform is accomplished ,Further this thesis focused on discussing how to design image collecting ,image coding ,and net work communication program .Finally ,the system is tested and the plan of further development is proposed.
