城市公共交通体系是城市社会经济系统的一个重要子系统,它的发展水平是衡量国家现代化程度的重要标志,同时也体现着国家的综合经济实力、城市经济的发展和城市居民的生活水平。
随着我国城市化的不断扩大,人口不断增多,城市交通的压力也随之增大,近几年智能交通的概念开始为人们所认识和接受。我国的城市公共交通体系的建设还处于初级阶段,管理相对落后,信息化水平不高。建立和优化智能交通系统可以明显的改善城市公共交通体系的管理水平,提高城市公共交通的社会效益。目前,国内多家公司都在进行公交车辆监控调度系统的研究,但因该系统的应用受到一些客观条件的限制,使得该系统的应用还没有得到广泛的普及。本论文就是在此背景下完成的,文中简要介绍了公交监控系统的组成,并重点论述了视频监控的设计与实现。
本文分析了视频监控系统的组成及监控中心的软件平台,其中对相关技术如视频采集、数据压缩的基本原理有特别的说明。

Abstract
The urban public traffic system is an important subsystem of the social economic system of a city, whose development level is not only a significant symbol of the national modernization, but also reflects the general economic strength of the country, the development of urban economy and the citizens’ living standard directly as well.
One that is with of our country urbanization constant to raise, population constant to increase, pressure increase too of city traffic. The concept of the intellectual traffic begins to be known and accepted by people in recent years. The construction of the urban public transportation system of our country is still on the primary stage with lagging behind management and the relatively low. Informationization level. Setting up and optimizing Advanced Public Traffic System can improve the manage mental level of the urban public traffic system obviously, thus create more social benefit of the urban public traffic. At present, many panies are doing research on the attempter and monitoring of buses. As confined with the conditions, the system has not received extensive application. In this thesis, a bus monitoring system is introduced briefly and great emphasis of this article is put on design and implementation of wireless video transmission system, and focuses on the design and implementation of video surveillance.
This thesis analyzes position of video surveillance systems and monitoring center software platform, including the related technologies such as video capture, pression, the basic principles of a particu
