无线监控服务资源提取算法

针对目前无线监控系统可控性、扩展性不足的问题,设计了一种能够进行大规模接入的分布式视频监控系统架构,提出了服务资源按类别先请求后提取、集中控制,监控终端集中管理的策略,并给出了数据资源、媒体资源的提取过程,最后通过服务器负载均衡算法和级联方案实现了接入容量扩展。实验结果表明,采用该算法的系统响应时间可以有效降低58%左右,最高能同时处理上万个监控前端服务请求。

Algorithm of Service Resources Acquisition Strategy inWireless Surveillance System

Service resource extraction is important to the efficiency of the system. In view of the controllability and scalability problem of present wireless monitoring system, this paper presents a distributed architecture of scalable surveillance system which can be implemented in city surveillance. Service resource can be obtained only after quarantine and then centralized to be controlled just like monitoring terminal. The extraction process of data resources, media resources and business resources and access capacity expansion scheme are introduced particularly. The results show that, the algorithm in this paper can effectively reduce the response time about 58%, and process tens of thousands of front-end monitoring request at the same time.
