【摘要】 Internet的飞速发展正在改变着我们的世界和生活。随着网络化和信息化时代的临近，各行各业都在寻找着自己的新的增长点。作为建筑群体中的一员，智能建筑凭借世界的网络化格局进入了高速发展时期，智能建筑中的防盗报警系统作为智能化系统中的子系统之一，同样面临着前所未有的挑战与机遇。传统的防盗报警系统是基于电话线的联网报警模式，其响应时间慢，使用和维护成本高，安全性和稳定性依赖于电话线路的使用状况，因此，系统的独立性差。反观基于总线式智能防盗报警系统通过建筑群内的局域网总线作为底层物理网络，彻底摆脱电话线模式的束缚，具有良好的开放性、独立性、可扩展性、高效性和经济性等特点。针对智能建筑群中业主的需求不同，对于防盗报警系统的功能要求也不尽相同。这就要求智能防盗报警系统既要易于使用、安装和维护，又要有利于扩展和升级，还要考虑到与该建筑群内的其他子系统进行有机的集成和信息共享，而计算机与通讯技术的发展将会对拟设计系统带来的影响也势必引起我们的关注。本论文设计实现一个构建于智能建筑局域网物理平台之上，采用Lonworks总线模式的智能防盗报警系统。并侧重介绍了建立系统的组成、系统结构。通过几种方案的对比，分析了所采用Lonworks现场总线模式的技术特点，进而明确了上位机的功能，并讨论了系统与智能建筑群中局域网的连接模式。运用软件工程思想详述了上位机软件的模块功能以及所涉及到的数据结构，描述了主程序工作流程以及下位机通信中的流程。最后，介绍了软件的编程实现技术，并简要介绍了提高系统可靠性的一些简便措施。更多还原

【Abstract】 The Internet burn the wind is changing our world and life. With the informationera coming near, every walk of life is looking for an own new growth to order. Be amember of building complex, the Intellectual Buildings enter a high-speeddevelopment period by right of the worlds turning to the network. As a sub-systemof the intellectual system in the Intellectual Buildings, the Intelligent Guard AgainstTheft and Alarm System is faced with the same challenges and opportunities as theIntellectual Buildings do.Traditional Intelligent Residence Guard Against Theft and Alarm System is analarm system on the basis of telephone lines, which has a long response time, highapplication and maintenance cost and low independence with the security andstability level depending on that of telephone networks. Contrarily, theMaster-slavery Guard Against Theft And Alarm System depends on local areanetwork in the building cluster as a physical network, thereby, getting away from thetie of the telephone line mode thoroughly, and takes on open capability,independencecapability, expand capability,efficiently capability and economic capability etc.Aiming at the need of the owner in the intelligence buildings, the function ofthe Guard Against Theft and Alarm System is not same. It must be easy to use andsetting and maintenance as well as spread and upgrade, and still have the ability tobe integrated and share information with other systems. The development from thecommunication technology and computer technology brought us.This paper designs and implements an Intelligent Residence Guard AgainstTheft and Alarm System, a master-slavery Lonworks network connected with localarea network. The structure and the constitution of the system and the structure ofcomputer networks are introduced. By comparing with the several diversifiedsolutions, the technical characteristics of the locale fieldbus are analyzed. Lonworkslocale connection solution is adopted to assign the functions of Upper LayerComputer and microcomputer-based lower control and to determine the communication protocols between Upper Layer Computer and microcomputer-basedlower control. According to the thinking of software engineering, the paper explaine thefunction of module and the data configuration to the committee and describe thework flow of main program. In the end, the paper introduce the technology of programmingand several measures of enhance reliability in the system.更多还原
