公交车查询系统的设计与实现

　　　　　　　　　　　摘  要

　　随着经济的发展，社会的进步，计算机越来越深入到我们日常的工作学习及生活中，成为我们日常生活中不可缺少的辅助工具。  随着科学技术的不断提高,计算机科学日渐成熟,其强大的功能已为人们深刻认识,它已进入人类社会的各个领域并发挥着越来越重要的作用。它已经深入到日常工作和生活的方方面面，比如文字处理、信息管理、辅助设计、图形图像处理、教育培训以及游戏娱乐等。各行各业的人们无须经过特别的训练就能够使用电脑完成许许多多复杂的工作。然而，虽然现在世界上已经充满了多如牛毛的各种软件，但它们依然不能满足用户的各种特殊需要，人们还不得不开发适合自己特殊需求的软件。以前开发Windows应用软件是专业人员的工作，需要掌握许多专业知识和经过特殊的培训才能胜任。现在不同了，即使你没有接受过严格的程序设计训练，使用Visual Basic也一样能够开发出功能强大、适合自己特殊需求的应用程序了。Visual Basic继承了Basic语言易学易用的特点，特别适合于初学者学习Windows系统编程。
   公交车查询管理系统用计算机管理公交车路线信息的一种计算机应用技术的创新,在计算机还未普及之前公交车查询管理都是由工作人们人工查询的方式来操作的.现在一般的公交车查询都采用计算机智能化管理,采用计算机作为工具的实用的计算机路线自动管理程序来帮助人们进行更有效的公交车路线查询。公交车查询管理系统是典型的信息管理系统(MIS),其开发主要包括后台数据库的建立和维护以及前端应用程序的开发两个方面。对于前者要求建立起数据一致性和完整性强、数据安全性好的库。而对于后者则要求应用程序功能完备,易使用等特点。
    经过分析,我们使用 MICROSOFT公司的 VISUAL BASIC开发工具,利用其提供的各种面向对象的开发工具,尤其是数据窗口这一能方便而简洁操纵数据库的智能化对象,首先在短时间内建立系统应用原型,然后,对初始原型系统进行需求迭代,不断修正和改进,直到形成用户满意的可行系统。
　　因为本人能力有限，加上时间紧迫，所以设计出来的本系统可能功能比较简单，另外本系统是单机版，不能实现网络互联操作,这些都有待于我在以后的工作学习中进一步改进。

Abstract

With economic development, social progress, the computer and went to work learning and our daily lives, we become an indispensable tool in everyday life. As science and technology continue to improve, computer science increasingly mature, and its powerful functions for the people to deeply understand that it has entered human society in various fields and is playing an increasingly important role. It has to go down to the daily work and life, such as word processing, information management, aided design, graphics and video processing, as well as education and training game entertainment. All people without special training will be able to use computers to complete numerous complex. However, although now the world has been filled with an over-abundance of software, but they still can not meet the special needs of the various users, it also had to develop software suited to their particular needs. Professional Windows application software development before the work is needed in many professional knowledge and competence through special training. Different now, even if you have not received strict procedures designed training, the use of Visual Basic also like to develop a powerful, and suited to their special needs applications. Visual Basic inherited Basic language learn user-friendly features, and are particularly suited to new learner learning Windows system programming.
Transportation vehicles using computer management information management system of a computer model cars line information technology application innovation in the computer before the public has not yet universal car enquiries are managed by the working people to operate manual enquiries. Now the general public enquiries have adopted computer intelligent vehicle management using the computer as a tool for automatic computer line management procedures to help people more effectively model cars line enquiries. Public enquiry management system is a typical car information management system (MIS), including its main development background to the establishment and maintenance of the database and front-end application development 2. The request for the establishment of strong data consistency and integrity, good for the security of the data. For the latter request applications functions, such as easy to use features.
After analysis, we use Microsoft visual basic development tool companies, the use of its various object-oriented development tools, especially data that can be easily accessible and concise window manipulation database intelligent objects, the first prototype application system in a short time and then, computation of the initial prototype system needs to constantly revise and improve until the formation of a viable system of user satisfaction.
Because I limited capacity, coupled with time constraints, it designed the system may function relatively simple, and the system is single edition, not Internet operations network, which I have yet to learn that in future work to further improve.

1．1 课题背景

     公交车查询管理系统用计算机管理公交车路线信息的一种计算机应用技术的创新,在计算机还未普及之前公交车查询管理都是由工作人们人工查询的方式来操作的.现在一般的公交车查询都采用计算机智能化管理,采用计算机作为工具的实用的计算机路线自动管理程序来帮助人们进行更有效的公交车路线查询。公交车查询管理系统是典型的信息管理系统(MIS),其开发主要包括后台数据库的建立和维护以及前端应用程序的开发两个方面。对于前者要求建立起数据一致性和完整性强、数据安全性好的库。而对于后者则要求应用程序功能完备,易使用等特点。

1．2 系统简介

本系统主要方便人们查询自己的公交车路线,方便人们乘坐公交.
本系统主要由以下几大功能组成:
一. 按车次查询模块
二. 按起终点站查询
三. 查找经过站点最小的路线
