矿区分布式网络视频录像系统设计

Design of distributed network video recording system for coal mine

针对传统集中式网络视频录像系统在多通道、大容量存储与多终端并发访问时,存在存储设备硬件处理能力不足和网络带宽局部拥塞现象,设计了一种分布式网络视频录像系统。该系统采用分布式IP架构,可实现视频数据的分布式物理存储和集中式逻辑管理;应用基于Socket的设备通信控制技术及基于应用层组播的回放控制技术,实现了设备管理和权限管理控制数据的交互及视频流的高效网络传输控制。测试结果表明,该系统较好地解决了矿区多通道、大容量的视频数据实时存储和远程回放问题。

In view of phenomenon that traditional centralized network video recording system hasinsufficient video processing capacity of storage device and network congestion when videos involve multichannel,large capacity and data concurrency,a distributed network video recording system was designed.The system adopts distributed IP architecture,and can realize distributed storage and centralized logic management of video data.The system also can realize control data interaction between device management and authority management and network transmission control of video streaming with application of Socket device management and playback control technology based on application layer multicast.The test results show that the system can solve problems of real-time storing and remote playback of multi-channel and large capacity video data in coal mine.
