本发明将在下文中参考附图描述, 附图中:
图 1是具体实施方式中视频监控系统的功能模块图;
图 2是具体实施方式中登录鉴权和获取 PU信息的流程图;
图 3是具体实施方式中录像查询流程图;
图 4是具体实施方式中录像播放流程图; 以及
图 5是具体实施方式中云台控制流程图。 本发明的较佳实施方式
本发明的基于 IPTV系统的视频监控系统包括:
监控前端 PU, 用于釆集现场的图像、 声音, 经压缩编码后在一定的条件 下进行本地存储或向指定的流媒体服务器发送流媒体数据, 内嵌相应软件的 设备, 包含摄像头、 编码器和云台;
业务管理子系统(PMS ) , 由多个服务器组成, 用于生成 URL, 并对监 控前端、 EPG进行管理;
RGM, 对监控前端与系统的交互提供管理, 分为 RGM Manager和 RGM Agent。 RGM Manager全局仅有一个, 负责编码器的注册、 为编码器分配为 其服务的 RGM Agent、 图片上传目标服务器和保活周期; RGM Agent全局可 有多个, 负责其他的与编码器相关的控制活动, 包括: 上线、 下线、 保活、 配置修改 /同步、 云台控制、 图片传输启动 /停止、 报警;

登录鉴权模块, 实现视频监控系统在 PMS中的登录鉴权。 由于视频监控 系统是绑定在 EPG子系统中的, 所以需要先在 EPG系统中进行鉴权, 实施 中, 可在 PMS 门户中事先开好户, 直接把用户名和密码传给 PMS, 进行登 录鉴权, 省去了一次 EPG系统的鉴权。
获取通道模块, 监控终端实现获取通道层次结构。 根据通道层次结构来 构建栏目树形结构, 通过緩存来加快构建的速度。
获取 PU静态信息模块, 用于监控终端获取 PU静态信息。 由于 PU的属 性非常多, 有几十个属性, 而且随着 PU的数量急剧增长将造成数据量庞大, 每次获取数据的时候系统压力很大。 因此把 PU不太会变化的属性作为静态 属性传递, 只有在静态属性发生改动的情况下, 才获取, 如果没有改动则只 获取一次, 以后就不再获取静态属性。 在用户登录鉴权的时候会有返回值告 知静态属性是否发生了改变, 据此来判断是否要去重新获取静态属性。
获取 PU动态信息模块, 用于监控终端获取 PU动态信息。 选取 PU经常 变化的属性提供单独的接口获取, 从而加快数据更新的速度。
视频播放模块, 实现 PU播放。 通过 HTTP消息, 或者 WINTCP消息两 种模式实现 PU的播放, 传送播放需要的参数给 CDN, 由 CDN控制 PU的播 放。
录像查询模块, 用于监控终端获取录像任务和录像文件。 网络视频监控 中观看录像文件是一个很重要的功能, 由于经常会 24小时不间断的监控, 造 成录像文件量很大, 而且监控保存为录像也可能是很小的时间段, 比如 5分 钟一段, 所以把录像文件获取设计为获取录像任务和录像文件两层的结构。 首先获取录像任务, 对于有多个文件的同一录像, 需要再次请求获取文件列 表, 并对文件列表进行分页获取, 减小传输的量, 加快速度。 录像播放模块, 实现在监控终端对录像文件的播放。
云台控制模块, 用于实现对云台的水平和垂直方向的控制。 通过 HTTP 消息实现对摄像头的光圈, 转向的控制, 实时控制 PU, 进行监控。
