图 1为本发明实施例中网络结构示意图；
图 2为本发明实施例中视频监控过程中录像中断恢复的方法流程图； 图 3为本发明实施例中视频监控系统的结构图。
本发明的较佳实施方式
下面将结合附图及实施例对本发明的技术方案进行更详细的说明。
图 1显示本发明的网络结构示意图， 摄像头通过前端 （Peripheral Unit, PU )与网络相连， PU可以是移动设备也可以为固定设备，客户端（ Client Unit , CU ) 可以通过移动网络或固定网络连接公网的注册管理子系统 （Register Manager System, RGM ) , 来观看视频或录像。
现有的录像监控系统中均保存有两个表： 录像计划表和录像任务表。 录 像计划表是由用户设定的， 其中保存有用户设定的各条录像计划的计划开始 时间及计划结束时间等； 录像任务表是录像监控系统根据录像计划表中的录 像计划动态更新的， 其中保存有各条录像任务的计划开始时间、 计划结束时 间及当前录像状态等信息， 当一条录像任务结束后， 录像监控系统会在录像 任务表中将该条录像任务删除。
本发明所述方法的基本构思是： 视频监控系统启动后， 对录像任务表中 的每一条录像任务进行扫描， 对于未过期的处于正在录像状态的录像任务， 则新建一条录像任务， 并将该条新建的录像任务下发给流媒体服务器， 其中， 该条新建的录像任务的计划开始时间为当前时间， 计划结束时间为该未过期 的处于正在录像状态的录像任务的计划结束时间； 流媒体服务器收到录像任 务后， 控制相应录像设备开始录像。 其中， 未过期的录像任务为计划结束时 间晚于当前时间的录像任务。
此外， 视频监控系统在对录像任务表进行扫描过程中， 还可以将已过期 的处于待录像状态的录像任务删除。
对于未过期的处于正在录像状态的录像任务， 视频监控系统除新建录像 任务外， 还向流媒体服务器发起异常查询请求流程， 查询该条录像任务的完 成情况； 对于已过期的处于正在录像状态的录像任务， 则直接向流媒体服务 器发起异常查询请求流程。
为了保证不浪费录像资源， 可以在视频监控系统中设置一第一阔值； 则 对于未过期的处于正在录像状态的录像任务， 新建一条录像任务是指： 对于 未过期的、 处于正在录像状态的、 且计划结束时间与当前时间的差值小于所
述第一阔值的录像任务， 新建一条录像任务。
由于视频监控系统中还保存有录像计划表， 因此在完成对所述录像任务 表中的每一条录像任务的扫描后， 开始对录像计划表中的每一条录像计划进 行扫描， 将计划开始时间早于当前时间且未过期的录像计划下发到录像任务 表中。 其中， 未过期的录像计划为计划结束时间晚于当前时间的录像计划。
同样地， 为了保证不浪费录像资源， 视频监控系统中设有一第二阔值； 在对录像计划表中的每一条录像计划进行扫描的过程中， 将计划开始时 间晚于当前时间且计划开始时间与当前时间的差值小于等于第二阔值的录像 计划下发到录像任务表中。
此外， 视频监控系统中设有一第三阔值； 则上述将计划开始时间早于当 前时间且未过期的录像计划下发到所述录像任务表中是指： 将计划开始时间 早于当前时间的、 未过期的、 且计划结束时间与当前时间的差值大于等于第 三阔值的录像计划下发到录像任务表中。
下面用本发明的一个应用实例进一步加以说明。
如图 2所示， 视频监控过程中录像中断恢复的方法包括以下步骤： 步骤一、 监控系统每次启动时， 触发录像状态检测程序， 从录像任务表 中选择一条录像任务进行扫描；
步骤二、 根据该条录像任务的状态信息判断其当前状态， 如为待录像状 态则执行步骤三； 否则执行步骤五；
步骤三、 判断该条录像任务是否已经过期 （即判断该条录像任务的计划 结束时间是否早于当前时间） ， 如果是则删除该条录像任务； 否则， 执行步 骤四；
步骤四、 判断是否已遍历录像任务表， 如果已遍历， 则执行步骤六； 否 则， 扫描下一条录像任务， 执行步骤二， ；
步骤五、 当前录像任务处于正在录像状态， 则表明该条任务是被迫中断 的任务， 此时需要恢复。 恢复的过程包括： 首先判断该条录像任务是否已过 期， 如果没过期且该条录像任务的计划结束时间与当前时间的差值大于等于
一设定的第一阔值（如 1分钟） ， 则在该录像任务表中新建一条录像任务， 该条新的录像任务的计划开始时间为当前时间， 计划结束时间为该条被迫中 断的录像任务的计划结束时间， 然后将该条新建的录像任务下发给流媒体服 务器， 并向流媒体服务器发起异常查询请求流程， 查询该条被迫中断的录像 任务的完成情况， 再执行步骤四； 如果该条录像任务已过期， 或该条录像任 务没有过期但其计划结束时间与当前时间的差值小于一设定的第一阔值， 则 直接向流媒体服务器发起异常查询请求流程， 然后执行步骤四；
步骤六、 从录像计划表中选择一条录像计划进行扫描；
步骤七、 判断该条录像计划的计划开始时间是否晚于当前时间， 如是则 执行步骤八， 否则执行步骤十；
步骤八、 判断该条录像计划的计划开始时间与当前时间的差值是否大于 一设定的第二阔值， 如是则执行步骤九； 否则， 将该条录像计划下发到录像 任务表中；
步骤九、 判断是否已遍历录像计划表， 如果已遍历， 则结束； 否则， 扫 描下一条录像计划， 执行步骤七；
步骤十、 判断该条录像计划是否已过期 （即判断该条录像计划的计划结 束时间是否早于当前时间） ， 如是， 则执行步骤九； 否则， 判断该条录像计 划的计划结束时间与当前时间的差值是否大于等于一设定的第三阔值，如是， 则将该条录像计划下发到录像任务表中， 并执行步骤九； 否则， 执行步骤九。
其中， 上述步骤五中的异常查询请求流程具体包括以下步骤：
RGM 中的录像模块会依据设计方案中的接口向流媒体服务器发起异常 查询请求消息， 流媒体服务器接到该查询请求消息后， 检查该录像任务目前 的录像情况， 并按设定的上报接口， 向 RGM录像模块上报该录像任务目前 录像的信息； RGM收到该上报的消息后， 根据该消息的内容， 做在录像任务 表中删除该录像任务、 写内存数据库、 写文件同步等一系列操作。
此外， 本发明还提供了一种视频监控过程中录像中断恢复的系统， 如图 3所示， 包括： 存储模块 31、 扫描模块 32、 录像任务创建模块 33、 任务下发
模块 34;
