【摘要】 随着社会的进步和高速公路的迅速发展，智能交通系统(ITS)的逐步实施，高速公路监控系统已经成为高速公路建设中的投资热点。交通领域应用软件的研究与开发成果，将有着广阔的应用前景和巨大的社会效益及经济效益。 该监控系统的研究开发，在吸收和借鉴国内外研究成果的基础上，充分采用了多种成熟的软、硬件技术，结合软件工程和面向对象的思想，完成对整个高速公路的监控。 本文先从高速公路监控系统的体系结构入手，提出了系统的网络结构；其次，分析了监控软件的组成和功能。由于该段高速公路路况复杂，沿线有多个隧道，部分路段还为雾区天气。所以该系统从功能上划分为三个子系统：路段监控、雾区监控和隧道监控；然后，对高速公路监控系统的部分软件进行的分析和设计；最后，实现了高速公路监控系统的部分软件，给出了主要的程序结构和用户界面。 在软件的开发过程中，遵循软件工程设计思想，按照工程的方法进行软件设计。对软件功能进行模块化功能细分，尽量做到各模块之间功能相互独立，模块接口尽量简单。并且在编码过程中，对一些可重复利用的代码进行封装，从而使程序结构简洁易读，修改灵活方便。并应用面向对象编程方法，来改善程序的复用性，减少软件维护的复杂性和开销。更多还原

【Abstract】 With the the society’s advancement, rapid development of freeway ,and the gradual implementation of the intelligent traffic system(ITS),The monitoring system of the freeway has already become the focus of investment in building freeway. Achievements of application research and development in field of traffic have very good social benefit and economic benefits.On the basis of using the results of domestic and international research for reference ,many kinds of ripe software and hardware technology,combined with the thought of software project and OOP, have fully adopted in this monitoring system to monitor the whole freeway..At first ,on the basis of analyzing the structure of the freeway monitoring system,the paper puts forward systematic network structure; Secondly,it has analysed the composition and function of the montoring software.Because this section of road conditions of freeway is very complicated ,and there are a lot of tunnels along the freeway,in addition,the weather of some freeway sections is fogy.The system is divided into three subsystems in the function: The freeway section controlling, the fogy district controlling and the tunnel controlling; Thirdly,the main software of the freeway monitoring system is analysed and designed in the dissertation;At last, the structure of procedure and user’s interface are given,and the monitoring software of the freeway is implemented.Following the software-engineering rule to develop the project,we divided the task into many simple and independent function units.The interface of all the units is as better as simple and independent.During the course of coding,we encapsulate some code,which can be used repeat,into some functions so we can reduce the complexity and the cost of the maintenance of our software.更多还原
