摘 要
近年来,视频监控因其直观、方便、快速的特点,在各行各业都得到了广泛的应用,特别是在小区安保、金融现场、交通控制以及国防安全等方面,已经成为视频监控渗透的主要领域。变电站作为电网系统中重要枢纽之一,利用视频监控能够强化变电站场所和重要设备的安全。但是,当前对于变电站场所内的监控以及大型设备的监控大多数还是基于传统有线局域网络的基础上实现的,这种方式需要通过复杂的布线、周密的布防才能完成,有线局域网的自身的局限性限制了变电站视频监控的发展,显现出监控范围小、传输性能低、可移动性差等缺点,无法满足越来越严峻的电力安全形势。因此,在变电站场所的视频监控方面,迫切需要进行完善,实现及时、灵活、方便的监控特点,保障监控任务的顺利完成。
本文主要工作在于研究、设计并实现了基于无线网状网的视频监控系统,主要内容包括:
1)无线网状网的基本理论进行了研究,包括无线网状网的概念、组成和基本结构,以及无线网状网的关键技术与优越性。
2)对实现基于无线网状网的变电站视频监控系统进行了可行性分析与需求分析,分别从技术、操作、经济及安全可行性方面进行分析,同时从功能需求、性能需求及安全需求方面进行了深入探讨
3)对无线网状网的变电站视频监控系统的总体架构进行了明确,设计了系统的功能模块,并就系统实现所需要的业务流程、数据库、安全性等方面展开全面设计
4)在全面设计的基础上,对系统进行实现,主要包括对系统无线网状网的配置、视频采集与控制模块的实现以及监控部署模块的实现,并针对完成的系统展开测试,测试结果能够满足变电站视频监控的需求。

ABSTRACT
Recent years, video surveillance because of its intuitive, convenient, fast, in all walks of life are widely used, especially in residential security, financial scene, traffic control and national defense security, has become the main areas of infiltration by video surveillance . Substation as one of the important hub in the grid system, the use of video surveillance to strengthen the security of the substation premises and equipment. Moreover, with the continuous development of Internet technology, computer network-based video surveillance to become one of monitoring the most common and most advanced application monitoring in most of the substation operation is automated. However, monitoring of the current monitoring of the substation premises and large equipment is lacking, this video monitor or traditional wired local area network based on the basis of, this approach requires complex wiring, and careful deployment to complete the wired LAN limitations restrict the development of the substation video surveillance, showing the scope of monitoring, low transmission performance, poor mobility shortcomings, simply can not meet the increasingly severe power security situation. Substation video surveillance of the premises, there is an urgent need to be refined to achieve a timely, flexible and convenient monitoring of the characteristics of successful completion of the protection of the monitoring task.
The main work of this paper is to study, design and implement a video surveillance system based on wireless mesh networks, the main contents include:
1) The basic theory of wireless mesh networks have been studied, including concept, composition and basic structure of the wireless mesh network, as well as wireless mesh network technology and superiority.
2) the realization of the feasibility analysis and demand analysis based on wireless mesh substation video surveillance system, respectively, from the technical, operational, economic and security terms of feasibility analysis, from both the functional requirements, performance requirements and security needs in-depth discussions
3) the overall architecture of the wireless mesh substation video surveillance system were clear, the design of the system functional modules, and systems to achieve the required business processes, database, security and other aspects of comprehensive design
4) on the basis of a comprehensive design, system implementation, including configuration of the wireless mesh network, video capture and control modules and monitor deployment of the module to achieve, and to complete the system to expand the test, the test results can meet the needs of the substation video surveillance.
