摘 要

校园监控系统是保障校园安全、维持正常稳定教学秩序的关键所在，传统的校园有线监控布线较为复杂且扩展困难，无法满足全面监控的基本需求。随着校园面积、在校师生人数的增加及人们对安全意识的提升，校园安全上升到不可以忽略的地位。本文在从系统设计需求出发，在详细分析了当前主流的通信技术、拓扑结构的基础上，设计了基于Wi-Fi技术的校园监控系统。

本文以Wi-Fi技术为基础，首先要详细介绍了802.11x协议族，全面分析了协议的特点以及不足，同时对常用的几种网络拓扑结构进行了深入的探讨。通过分析和研究，综合了解了WLAN网络标准和拓扑结构，为最终实现监控系统提供充理论支持。

其次介绍了开发工具及开发环境。本课题采用微软公司开发的基于.NET平台的集成开发环境visual studio，数据库的要求较为简单，使用的是SQL server 2008版，编写语言用C#来实现软件功能。同时分析了整个系统的设计目标，确定了系统的设计原则，在此基础上完成了系统软件总体设计。

然后是监控系统的详细设计。根据校园监控系统的需求分析，详细设计了系统的软件架构和交互界面并以此为基础实现系统服务端的功能。监控服务端是整个校园监控系统的重要组成部分，用户通过服务端可以进行学生信息管理和位置管理等操作。

最后运行系统测试系统情况，经过系统测试分析，验证了系统安全可靠、扩展灵活、简单实用、等优点，实现了系统的需求功能和设计目标。

ABSTRACT

The campus monitoring system is the key to guarantee the campus security and maintain the normal and stable teaching order. The traditional wired monitoring system is more complex and difficult to expand, which can not meet the basic needs of the overall monitoring. With the increase of the campus area, the number of teachers and students, and the promotion of safety awareness, the campus security should not be ignored. Based on the requirement of system design, this paper analyzes the current mainstream communication technology and the topology structure, and designs the campus monitoring system based on Wi-Fi technology.

The Wi-Fi technology as the foundation, first of all to 802.11x protocols are introduced in detail in this paper, a comprehensive analysis of the advantages and disadvantages of the agreement, also on several common network topology were in-depth study, through the analysis and research, a comprehensive understanding of the WLAN standards and network topology, filling theory support for the ultimate realization of a wireless system.

Secondly introduces the development tools and development environment. This topic is based on the.NET platform developed by Microsoft Corp, which is based on the integrated development environment studio visual, the database is relatively simple, the use of server SQL 2008 edition, the preparation of language using C# to achieve software functions. At the same time, the design goal of the whole system is analyzed, the design principle of the system is confirmed, and the overall design of the system software is completed.

Then it is the detailed design of the monitoring system. According to the requirement analysis of the campus monitoring system, the system"s software architecture and interface are designed in detail, and the function of the system server is realized. Monitoring server is an important part of the entire campus monitoring system, the user can carry out the management of student information management and location management.

Finally, the system test system is tested and analyzed, which proves that the system is safe, reliable, flexible, simple and practical, and can achieve the requirement and design goal of the system.
