【摘要】 安全防范系统在政治、军事、文化、生产和生活设施的安全保卫中一直起着举足轻重的作用。随着计算机网络与通信技术、多媒体技术的快速发展,数字化、网络化和智能化已经成为安全防范系统的重要研究内容。将军集团济南卷烟厂为了扩大生产规模、提高技术水平,于2006年9月开始实施易地技术改造项目。新厂区总占地面积1000多亩,包括生产区、办公区和生活区二十多个建筑物。如何对建设中和将来运行中的新厂区开展有效的安全防护工作,是一个急需解决的问题。本文通过对新厂区的实地考察,设计了一套基于数字网络技术的功能强大、技术先进的安全防范系统。该系统用于对新厂区进行实时防护和管理,对于保证厂区财产安全和生产的正常进行具有重要的意义。同时该系统还可以用于重要房间和通道的进出管理,防止无关人员进入,记录出入人员身份和时间信息,有利于提高企业的管理水平。本文首先对系统进行了总体设计,包括数字视频监控系统、门禁管理系统和防盗报警系统共三个子系统。三个子系统各自独立,又相互联动,组成厂区安全防范的一个整体系统。然后在对各子系统进行需求分析的基础上,对现场设备进行了深化设计与选型;对Honeywell EBI软件和DVM软件在本系统中的应用进行了详细介绍,并对子系统联动功能的实现进行了深入研究;另外设计建立采用第三层交换和VLAN技术的安防系统专用网络,对于系统网络视频传输流量较大的特点,提出了以卡尔曼滤波器理论为基础,基于RTCP反馈的网络拥塞控制,保证了传输的稳定畅通。本文对网络通信、流媒体传输、EBI软件和DVM软件应用、信号处理、和网络拥塞控制等问题进行了深入的研究,对工程实际中所遇到的问题进行了深入分析并给出了解决方案。该系统是济南卷烟厂易地技术改造项目中的一个重要系统,它的成功建设将解决济南卷烟厂安全保卫问题,而且其设计思想对于范围广阔的地区进行多点综合安全防范也具有一定的实用价值。更多还原

【Abstract】 Security systems has been playing an important role in the protection of political, military, cultural, and living facilities. With the rapid development of networks, communications and multimedia technology, digital networking and intelligent security system has become an important research topic.In order to expand the scale of production, raising the technological level, General Group, JiNan cigarette factory started the technological transformation projects in September 2006. The new plant covers an area of 1000 mu, including production, office and living areas more than 20 buildings. How the construction and future operation of the new plant to carry out effective security protection is an urgent problem.Based on the inspection of the new factory, we designed a powerful and advanced security system which is based on digital network technology. The system is used for real-time protection of the new plant and management. To guarantee the safety of property and normal production is of great significance. At the same time the system can be used to access the important rooms and channels, prevent the entry of unauthorized person, and record the personal identity and time information. It is conducive to improving the whole security management level.In this paper, we designed the whole system, including digital video systems, access control systems and anti-theft alarm system. The 3 separate subsystems are also interactive. Based on the analysis of the subsystem needs, we designed and selected the equipment.Then it introduced the application of Honeywell EBI and DVM software in details, and the researching of linkage between the 3 subsystems.We also designed the security network system which is established based on the third layer interaction and VLAN technology. For the high traffic of video transmission in the network, we put forward a network congestion control theory based on Kalman filter and RTCP feedback theory to ensure the stable transmission.We showed the deeply reseach of network communications, streaming media transmission, the applications of DVM and EBI software, signal processing, and network congestion control theory in this paper. We gave the solutions of the practical engineering problems by the in-depth analysis. This system plays an important role in the transformation projects of JiNan cigarette factory, and its success will solve the security problems.And its design ideas for a broad range of areas and more comprehensive security system also has some practical value.更多还原
