【摘要】 随着经济的发展和人民生活水平的提高,人们越来越重视安全,巡更系统则是在这种要求下应运而生。传统的巡更制度是采用人工方式,不利于对保安人员的管理。为了防止各种人为错误的发生以及方便管理,需要建立一套现代化的巡更系统。随着科技的发展,智能化的巡更系统已是现代化管理的重要手段之一。在进入信息化社会的今天,电脑应用系统己渗透到各个角落。因此建立一个全方位、多层次、立体化及高效率的巡更管理系统己成为物业管理的一项重要内容。 本论文正是以此为背景,研究了一种感应式射频(RF)卡技术在巡更系统中的应用,并依托感应卡的强大优势,以Visual Basic为前台开发工具,以SQL Server为后台运行数据库,独立开发了一套完整的巡更系统管理软件。本文所介绍的巡更管理系统还能够实现一卡多用的功能,有较强的系统扩展性。 在本文中,首先介绍了感应卡巡更系统的相关知识及其工作原理。在此基础之上,通过对系统的需求分析,具体阐述了一种巡更系统的设计方案。接着,通过对系统串行通信协议的分析,介绍了上位机的通信流程,并把PC机串口与控制器通讯接口部分之间的协议封装成动态链接库的形式,供上层应用程序调用。最后在软件模块化结构的基础之上,着重介绍了实时监控及报警模块、权限管理模块、控制器参数设置模块、卡片及人事信息管理模块、查询/报表模块和系统维护模块等的具体实现过程。 最后,从硬件和软件的角度,论证了系统的安全性。更多还原

【Abstract】 With development of economy and improving of people’s living level, people have greater importance on safety, patrol systems develop on this circumstances. Traditional patrol systems run in manual way, it’s difficult to manage. In order to prevent various man-made errors and manage easily, it is absolutely necessary to set up a set of modern intelligent patrol systems. With the development of science and technology, intelligent patrol system is a kind of important measure in the modern management. Today, we have come into the information world and computer application systems have already penetrated each corner of our society. Therefore, it is an important task to set up the management information system of stakeout in the management of real estate, which is all-directions, tier and high-efficiency. Furthermore, a patrol system is an important part in it.With the background, the application of Proximity Card in a patrol system is introduced. With Visual Basic as proscenium development tool and SQL Server as the operation database of backstage supporter, the full software about Patrol Management System is developed all alone on the basis of proximity card’s strong advantages. The Patrol System introduced by this paper has preferable expansibility.Firstly, the knowledge and work principles, which are related to the Patrol System of Proximity Card, are introduced in the paper. According to requirements, a project to Patrol System is set forth in detail. Secondly, the communications flow of computer is introduced according to the analysis of serial communication protocols. And the protocols between computer’s serial port and controller’s communication interface is encapsulated as Dynamic Link Libraries in order to be applied to application. Lastly, on the basis of software modularization, the realization of some modules is explained in detail, such as, real-time control and alarm, management of rights, setting of controller’s parameter, management of card and person, query and report, system maintenance.Finally, system security is demonstrated from hardware and software.更多还原
