文档介绍：ADissertation Submitted to Shanghai Jiao Tong University for Master Degree of Engineering mand System Design and analysis based on IP Author :Huang Yeliang Specialty: Electronics munication Engineering Advisor Ⅰ: Yang Hua Associate professor Advisor Ⅱ:Dr. Peng Xiang School of Electronics and Electric Engineering Shanghai Jiao Tong University Shanghai, December 2, 2013 万方数据上海交通大学工程硕士学位论文摘要第 I 页上海交通大学工程硕士学位论文基于IP 的现代警务指挥指挥系统摘要当今公安机关原有的警务指挥系统功能仅限于视频会议,可以完成指令的上传下达,但是因为与图像监控系统相互独立,不能相互共享图像资源,在实时处置各类案件的警务指挥过程中,难以将视频会议的直观与监控图像的实时临场的特点充分结合起来,由于是两套独立的系统, 在操作上也较为复杂,而且仅限于本地大屏的图像切换,不能控制下一级警务指挥机构的显示系统。现有系统已难以适应当前日趋复杂社会治安形势以及特大型国际大都市城市治安管理工作又对公安警务指挥工作提出的新的挑战。本文对公安机关现有的传统警务指挥系统进行分析,阐明了其优势和缺点。针对原有系统功能单一, 与其他系统不能产生联动的不足之处, 结合公安机关信息化应用和建设水平现状,研究探索了基于IP 网络的现代警务指挥系统。例举并对已成功应用的案例进行分析,对系统方案的可行性进行了测试和论证。通过本文的阐述论证,设计了以网络技术和视音频技术为基础设计万方数据上海交通大学工程硕士学位论文摘要第 II 页的现代警务指挥系统。系统以视频语音技术、图像处理技术、网络通信等技术为基础,可实现分散在各地的警务人员(或警务机构)之间的互联互通、即实沟通与资料共享,从而实现视频会议、数据交互、应急指挥等应用功能。该系统能够实现公安警务指挥实战中警务指令的研判与下达与事件现场实时情况的高度融合和互动。论证了技术不仅是对公安工作的有力支撑,更能够有效引导警务指挥工作机制向高效率转变和提升。关键词: 视频会议,治安监控联动,数据共享,以太网技术、音视频编解码万方数据上海交通大学工程硕士学位论文 ABSTRACT 第 III 页 mand SystemDesign and Analysis based on ABSTRACT Nowadays, the traditional mand system of Public Security only focus the function of a udio-visual conference, and some mand like data upload and download. Because of the isolation between traditional mand system and the monitor system, these two systems can’t exchange the video resource. For ex ample, when accident happened, it is difficult bine the function of aud io-visual conference and real-time monitor directly, which is critical important for the police to make upon the decision. Additionally, the operation o f the traditional mand system is plicated. The system could only realize the function of monitor cut, still missing the function of controlling sub-level monitor-cutting system. Besides, the plexity of the society security and the management pressure of metropolis security take the new challenge to the public man
