【摘要】：现代高档智能小区的快速发展对小区安防的覆盖、便捷、性能等指标都提出了越来越高的要求,对安全可靠的家居生活需求也越来越迫切。构建平安社会,加强技术防范与威慑成为新建小区的刚性需求。DVR监控系统因其成本低,效果好,易拓展等特性,已广泛应用于安防领域。本论文针对小区安防的需求,构建了以人为本,人防技防相结合的人性化小区安防直播系统模型。以DVR技术为核心进行直播系统的应用为主要的研究对象,在深入分析TCP/IP协议与Winsock编程的基础上,对小区安防直播系统流媒体服务器构建、指挥调度算法策略进行了详尽的讨论和研究。本文的主要内容为:1.对当前小区安防监控系统的工作模式进行研究,提出了一种全民参与的新型小区安防监控体系。该方法通过向全体授权居民开放公共区域的视频监控,让居民参与到小区安防中来,进而提升了小区的安防等级与层次,实现了在现有技术储备的前提下完成的一种新型应用。2.研究流媒体服务器的构建,对DVR及客户端的工作过程及工作原理进行分析,并提出了使用SDK进行敏捷开发的思路。3.研究负载分流指挥调度算法,提出了在小区内架设调度服务器进行应用分层,对流媒体进行虚拟化的可行办法。以DVR为核心的小区安防直播系统是在当前技术层面全面提升小区安防水平而进行设计的,这一技术的应用,将会推动整个建筑行业小区安防产业的深入发展。
[Abstract]:The rapid development of modern high-grade intelligent community has put forward higher and higher requirements for the coverage, convenience, performance and other indicators of residential security, and the need for safe and reliable household life is becoming more and more urgent. Strengthening the technology prevention and deterrence has become the rigid demand of the newly built residential area. DVR monitoring system has been widely used in the field of security because of its low cost, good effect, easy to expand, etc. This paper aims at the demand of residential security. This paper constructs a humanized residential security direct broadcast system model based on people-oriented, civil air defense technology and defense. The main research object is the application of direct broadcast system based on DVR technology. Based on the analysis of TCP/IP protocol and Winsock programming, the streaming media server of residential security direct broadcast system is constructed. The strategy of command and scheduling algorithm is discussed and studied in detail. The main content of this paper is: 1. The working mode of the current residential security monitoring system is studied. In this paper, a new type of residential security monitoring system is proposed, which allows residents to participate in community security by opening up video surveillance in public areas to all authorized residents. Furthermore, it improves the security level and level of the community, realizes a new application. 2. Research the construction of streaming media server under the premise of the existing technology reserve. The working process and working principle of DVR and client are analyzed, and the idea of agile development using SDK is put forward. 3. The algorithm of load shunt command and scheduling is studied. In this paper, it is proposed to set up a dispatching server in the residential area for application stratification. DVR as the core of the residential security direct broadcast system is designed in the current technical level to improve the security level of the community, the application of this technology. Will promote the entire construction industry residential security industry in-depth development.
