基于广电网络城市监控网络系统的设计 摘要 论述利用广电光纤网构建城市监控网络系统的可行性 介绍有线电视HFC网结构、城市监控系统的设计需求、总体构架；控制与交换相分离适合大规模扩展应用。控制、图像、存储等全部采用国际标准技术实现，便于互连互通，整体架构采用分层、开放设计，便于新技术新业务的引入及融和视频编、解码器网络视频存储系统Based on broad electric network city monitoring network systems design ABSTRACT The elaboration uses the broad electricity optical fiber net to construct the city monitoring network system the feasible Introduction cable TV HFC net structure, the city supervisory system design demand, the over all skeleton. The control and the exchange separates, suits the large-scale expansion application. The control, the image, the memory and so on use the international standard technology realization completely, is advantageous for the interconnection intercommunication, the overall construction uses the lamination, the opening design, is advantageous for the new technical new service introduction and the fusion. The IP intelligence monitoring construction, the video frequency arranges the decoder, the network video frequency memory system as well as the network transmission and the key technologies. Introduction supervisory system front end pickup device, image signal transmission network, monitoring control, management, control center and so on each constituent unique feature. The supervisory system carries out practical, advanced, the economy” this principle of design, embarks from the reality, the system by the onstage pickup device, the backstage system handling equipment and the transmission part constitution, the onstage evidence collection is the system foundation, the background processing is the system core, the transmission part realizes the system real-time function bridge. Key words: Supervisory system Video frequency matrix cut Light end machine DVR hard disk vide目 录 摘要 I ABSTRACT II 绪 论 1 一. 概 论 1 （一） 广电网络构建城市监控网络系统的可行性 1 （二） 基于广电网络城市监控网络系统总体设计原理 1 （三） 监控系统的建设目标 4 （四） 系统建设原则 5 二. 智能监控系统总体设计构架 5 （一） 传统监控联网建设模式分析 5 （二） IP智能监控架构 7 （三） 视频监控特征分析： 8 三. 系统特点 10 （一） 统一的监控平台 10 （二） 先进的系统构架 11 四. 系统设计内容简述 11
