具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例公开了一种基于传输时长的物联网数据上报控制方法及转发节点，能够优先上报传输时长较大的物联网数据，降低了传输时长较大的物联网数据的传输时延，进而能够使汇聚单元尽可能及时的接收到物联网数据。以下分别进行详细说明。
为了更好地理解本发明实施例，下面先对本发明实施例公开的一种物联网架构进行介绍。请参阅图1，图1是本发明实施例公开的一种物联网架构的示意图。如图1所示，该物联网架构按照功能划分可以包括终端设备层、转发节点层以及汇聚层三个层。其中，终端设备层可以包括海量规模的终端设备，例如湿度计、烟感器、通风设备、雨量传感器、灌溉阀等等；转发节点层可以包括网络连接的大量的转发节点，转发节点可以包括路由器、中继器、接入点等设备，本发明实施例不作限定；转发节点可以使用任何标准的组网协议，而且转发节点可以在不同的网络制式之间实现数据解析；汇聚层可以包括过滤网关和汇聚单元，其中，过滤网关可以通过互联网与转发节点层的各个转发节点直接或简介通讯连接；汇聚单元可以通过过滤网关对转发节点层的各个转发节点进行高层管理，从而实现数据传输频率、网络拓扑以及其他组网功能的控制；汇聚单元不仅可以对海量终端设备产生的物联网数据进行分析和决策，还可以通过发指令去获取信息或者配置终端设备参数(此时数据的传输指向终端设备)；汇聚单元还可以引入各种业务，从大数据到社交网络、甚至从社交工具“点赞”到天气分享等。在图1所示的物联网架构中，每一个转发节点可以为其自身无线覆盖范围内的海量终端设备提供物联网数据收发服务，其中，每一转发节点自身无线覆盖范围内的每一个终端设备可以内置有无线通讯模块，这使得每一转发节点可以通过无线网络通讯方式与自身无线覆盖范围内的每一个终端设备进行无线通讯。在图1所示的物联网架构中，终端设备内置的无线通讯模块在生产时，可以输入上频点470MHz，下频点510MHz，这样无线通讯模块可以自动将通讯频段定义为470MHz～510MHz，以符合中国SRRC标准的规定；或者，也可以输入上频点868MHz，下频点908MHz，这样无线通讯模块可以自动将通讯频段定义 为868MHz～908MHz，以符合欧洲ETSI标准的规定；或者，可以输入上频点918MHz，下频点928MHz，这样无线通讯模块可以自动将通讯频段定义为918MHz～928MHz，以符合美国FCC标准的规定；或者，无线通讯模块的通讯频段也可以定义为符合日本ARIB标准或加拿大IC标准的规定，本发明实施例不作限定。在图1所示的物联网架构中，终端设备可以采用频分复用(Frequency Division Multiple Access，FDMA)、跳频(Frequency-Hopping Spread Spectrum，FHSS)、动态时分复用(Dynamic Time Division Multiple Access，DTDMA)、退避复用(CSMA)相结合的方法来解决干扰问题。
实施例一
请参阅图2，图2是本发明实施例公开的一种基于传输时长的物联网数据上报控制方法的流程示意图。如图2所示，该基于传输时长的物联网数据上报控制方法可以包括以下操作：
201、转发节点侦听其无线覆盖范围内的多个终端设备上报的物联网数据，每个物联网数据包括数据内容以及该物联网数据的上报时刻。
本发明实施例中，终端设备向转发节点上报的物联网数据可以包括数据内容，其中，物联网数据包括的数据内容用于表示终端设备上报的数据负载，例如农场部署的湿度感知终端设备上报的物联网数据包括的数据内容可以是土壤容积含水量；又例如，温度传感器上报的物联网数据包括的数据内容可以是温度值；又例如，雨量计上报的物联网数据包括数据内容可以是降雨量。
其中，终端设备向转发节点上报物联网数据可以包括：
由终端设备监测终端设备与转发节点之间的无线端口的负荷值，并判断该负荷值是否低于指定负荷阈值，如果该负荷值低于指定负荷阈值，则由终端设备识别终端设备的当前系统时间是否处于转发节点指定的允许上报物联网数据的时间段内，如果该当前系统时间处于转发节点指定的允许上报物联网数据的时间段内，则由终端设备向转发节点上报物联网数据。这样能够使终端设备在转发节点允许的时间段内以及在无线端口的负荷值较小的情况下进行上报，能够缓解上报压力并提高终端设备成功上报物联网数据的可靠性。
202、转发节点确定其侦听到每个物联网数据的侦听时刻，以及根据每个物联网数据的上报时刻以及侦听时刻确定每个物联网数据的传输时长。
本发明实施例中，每个物联网数据的传输时长等于转发节点侦听到该物联网数据的侦听时刻减去每个物联网数据包括的该物联网数据的上报时刻。
203、转发节点根据每个物联网数据的传输时长确定每个物联网数据的上报优先级，并将上报优先级相同的物联网数据封装成数据元，得到不同上报优先级的数据元。
本发明实施例中，不同传输时长的物联网数据的上报优先级可能相同，也可能不同，当不同传输时长的物联网数据的上报优先级不同时，物联网数据的传输时长越长，该物联网数据对应的上报优先级就越高。具体的，转发节点根据每个物联网数据的传输时长确定每个物联网数据的上报优先级可以包括：
转发节点根据每个物联网数据的传输时长确定该传输时长所属的时长范围，并根据其所属的时长范围确定该物联网数据的上报优先级。
204、转发节点按照上报优先级由高到底的顺序依次向汇聚单元上报对应的数据元。
在一个可选的实施例中，该基于传输时长的物联网数据上报控制方法还可以包括以下操作：
转发节点接收过滤网关下发的兴趣指示消息并存储，其中，该兴趣指示消息用于指示汇聚单元感兴趣的物联网数据，例如，汇聚单元感兴趣的物联网数据可以为包含的数据内容为预设数据内容的物联网数据等。
其中，转发节点按照上报优先级由高到底的顺序依次向汇聚单元上报对应的数据元可以包括：
转发节点按照上报优先级由高到底的顺序确定待上报的数据元，并判断该待上报的数据元中是否包含上述兴趣指示消息所指示的汇聚单元感兴趣的物联网数据，当包含上述兴趣指示消息所指示的汇聚单元感兴趣的物联网数据时，向上述汇聚单元上报该待上报的数据元；
当不包含上述兴趣指示消息所指示的汇聚单元感兴趣的物联网数据时，转发节点过滤掉该待上报的数据元，并按照上报优先级由高到底的顺序确定下一个数据元作为新的待上报的数据元，以及触发执行上述判断待上报的数据元中是否包含上述兴趣指示消息所指示的汇聚单元感兴趣的物联网数据的操作。
该可选的实施例能够只上报汇聚单元感兴趣的物联网数据，并过滤掉汇聚单元不感兴趣的物联网数据，这样能够减轻转发节点的上报负担以及汇聚单元的处理负担。
可见，实施图2所描述的基于传输时长的物联网数据上报控制方法能够优先上报传输时长较大的物联网数据，降低了传输时长较大的物联网数据的传输时延，进而能够使汇聚单元尽可能及时的接收到物联网数据。
实施例二
请参阅图3，图3是本发明实施例公开的另一种基于传输时长的物联网数据上报控制方法的流程示意图。如图3所示，该基于传输时长的物联网数 据上报控制方法可以包括以下操作：
301、转发节点侦听其无线覆盖范围内的多个终端设备上报的物联网数据，每个物联网数据包括数据内容以及该物联网数据的上报时刻。
302、转发节点确定其侦听到每个物联网数据的侦听时刻，以及根据每个物联网数据的上报时刻以及侦听时刻确定每个物联网数据的传输时长。
303、转发节点根据每个物联网数据的传输时长确定每个物联网数据的上报优先级，并将上报优先级相同的物联网数据封装成数据元，得到不同上报优先级的数据元。
304、转发节点判断得到的数据元的总数量是否大于等于预设数量阈值。
本发明实施例中，当步骤304的判断结果为是时，触发执行步骤305-步骤306；当步骤304的判断结果为否时，触发执行步骤307。
305、转发节点按照上报优先级由高到底的顺序确定出预设数量阈值的数据元，并按照上报优先级由高到底的顺序依次向汇聚单元上报该预设数量阈值的数据元。
306、转发节点将除上述预设数量阈值的数据元之外的剩余数据元发送至转发节点无线覆盖范围内的上报负荷最小的相邻转发节点，以触发该相邻转发节点按照上报优先级由高到底的顺序依次上报剩余数据元。
本发明实施例能够在转发节点需要上报的数据元数量较多时，由该转发节点无线覆盖范围内上报负荷最小的相邻转发节点分担转发节点的上报压力，这样不仅可以均衡转发节点的上报压力，还能够提高其他转发节点的上报资源的利用率。
307、转发节点按照上报优先级由高到底的顺序依次向汇聚单元上报对应的数据元。
在一个可选的实施例中，该基于传输时长的物联网数据上报控制方法还可以包括以下操作：
转发节点接收过滤网关下发的兴趣指示消息并存储，其中，该兴趣指示消息用于指示汇聚单元感兴趣的物联网数据，例如，汇聚单元感兴趣的物联网数据可以为包含的数据内容为预设数据内容的物联网数据等。
其中，转发节点按照上报优先级由高到底的顺序依次向汇聚单元上报对应的数据元可以包括：
转发节点按照上报优先级由高到底的顺序确定待上报的数据元，并判断该待上报的数据元中是否包含上述兴趣指示消息所指示的汇聚单元感兴趣的物联网数据，当包含上述兴趣指示消息所指示的汇聚单元感兴趣的物联网数据时，向上述汇聚单元上报该待上报的数据元；
当不包含上述兴趣指示消息所指示的汇聚单元感兴趣的物联网数据时，转发节点过滤掉该待上报的数据元，并按照上报优先级由高到底的顺序确定下一个数据元作为新的待上报的数据元，以及触发执行上述判断待上报的数据元中是否包含上述兴趣指示消息所指示的汇聚单元感兴趣的物联网数据的操作。
该可选的实施例能够只上报汇聚单元感兴趣的物联网数据，并过滤掉汇聚单元不感兴趣的物联网数据，这样能够减轻转发节点的上报负担以及汇聚单元的处理负担。
在另一个可选的实施例中，该基于传输时长的物联网数据上报控制方法还可以包括以下操作：
转发节点根据上述兴趣指示消息确定其无线覆盖范围内上报汇聚单元感兴趣的物联网数据的所有终端设备，并判断该所有终端设备中是否存在针对汇聚单元感兴趣的物联网数据的上报频率小于等于预设上报频率的至少一个终端设备，当存在该至少一个终端设备时，向该至少一个终端设备中的每个终端设备发送上报频率上调指令，以触发该至少一个终端设备中的每个终端设备上调针对汇聚单元感兴趣的物联网数据的上报频率。这样能够提高汇聚单元接收到其感兴趣的物联网数据的可靠性。
在另一个可选的实施例中，在转发节点根据每个物联网数据的传输时长确定每个物联网数据的上报优先级之前，该基于传输时长的物联网数据上报控制方法还可以包括以下操作：
转发节点判断上述多个终端设备上报的物联网数据中是否存在传输时长大于等于预设时长阈值的物联网数据，当不存在传输时长大于等于预设时长阈值的物联网数据时，触发执行上述根据每个物联网数据的传输时长确定每个物联网数据的上报优先级的操作；
当上述多个终端设备上报的物联网数据中存在传输时长大于等于预设时长阈值的物联网数据时，转发节点过滤掉上述多个终端设备上报的物联网数据中传输时长大于等于预设时长阈值的物联网数据，得到更新后的海量物联网数据，并触发执行步骤303-步骤307。这样可以过滤掉时效性较低的物联网数据，进而降低转发节点的上报负担以及汇聚单元的处理负担。
可见，实施图3所描述的基于传输时长的物联网数据上报控制方法能够优先上报传输时长较大的物联网数据，降低了传输时长较大的物联网数据的传输时延，进而能够使汇聚单元尽可能及时的接收到物联网数据。

进一步可选的，确定单元402还可以用于根据上述兴趣指示消息确定其无线覆盖范围内上报汇聚单元感兴趣的物联网数据的所有终端设备。
第一判断单元405还可以用于判断确定单元402确定出的所有终端设备中是否存在针对汇聚单元感兴趣的物联网数据的上报频率小于等于预设上报频率的至少一个终端设备。
通信单元406还可以用于当第一判断单元405判断出存在针对汇聚单元感兴趣的物联网数据的上报频率小于等于预设上报频率的至少一个终端设备时，向该至少一个终端设备中的每个终端设备发送上报频率上调指令，以触发该至少一个终端设备中的每个终端设备上调针对汇聚单元感兴趣的物联网数据的上报频率。
在另一个可选的实施例中，该转发节点400还可以包括第二判断单元408以及过滤单元408，此时，该转发节点400的结构可以如图6所示，图6是本发明实施例公开的又一种转发节点的结构示意图。其中：
第二判断单元408用于在确定单元402根据每个物联网数据的传输时长确定每个物联网数据的上报优先级之前，判断上述多个终端设备上报的物联网数据中是否存在传输时长大于等于预设时长阈值的物联网数据，当不存在传输时长大于等于预设时长阈值的物联网数据时，触发确定单元402执行上述根据每个物联网数据的传输时长确定每个物联网数据的上报优先级的操 作。
过滤单元409用于当第二判断单元408判断出上述多个终端设备上报的物联网数据中存在传输时长大于等于上述预设时长阈值的物联网数据时，过滤掉上述多个终端设备上报的物联网数据中传输时长大于等于上述预设时长阈值的物联网数据，得到剩余物联网数据。
确定单元402还可以用于确定过滤单元409过滤得到的剩余物联网数据中每个物联网数据的上报优先级。
封装单元403还可以用于将上述剩余物联网数据中上报优先级相同的物联网数据封装成数据元，得到不同上报优先级的数据元，并触发上报单元404执行按照上报优先级由高到低的顺序依次向汇聚单元上报对应的数据元的操作。
可见，实施图4-图6任一项所描述的转发节点400能够优先上报传输时长较大的物联网数据，降低了传输时长较大的物联网数据的传输时延，进而能够使汇聚单元尽可能及时的接收到物联网数据。
