实施例一
在图1所描述的物联网架构的基础上，本发明实施例公开了一种基于场景信息的物联网数据智能过滤方法。请参阅图2，图2是本发明实施例公开的一种基于场景信息的物联网数据智能过滤方法的流程示意图。如图2所示，该基于场景信息的物联网数据智能过滤方法可以包括以下步骤：
201、转发节点接收其自身无线覆盖范围内的海量的终端设备发起的物联网数据；其中，每一终端设备发起的物联网数据包括终端设备标识、终端设备类型以及数据负载内容。
本发明实施例中，终端设备标识用于表示终端设备的唯一身份，而终端设备类型用于表示终端设备的类别和型号，数据负载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数据负载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数据负载内容可以是温度值；又例如，雨量计上报的物联网数据包括数据负载内容可以是降雨量。
202、转发节点以每一终端设备发起的物联网数据包括的终端设备标识为依据，获取该终端设备的终端设备标识对应的终端设备地址；以及，获取该终端设备地址对应的天气类型信息作为该终端设备所在地的场景信息。
本发明实施例中，转发节点可以存储其自身无线覆盖范围内的每一终端设备的终端设备标识，其中，转发节点存储的每一终端设备的终端设备标识还可以绑定该终端设备的终端设备地址；其中，终端设备地址可以是终端设备的物理坐标地址，也可以是终端设备的网络IP地址，本发明实施例不作限定。
作为一种可选的实施方式，上述步骤202中，转发节点获取该终端设备地址对应的天气类型信息作为该终端设备所在地的场景信息的方式可以为：
转发节点可以调用该终端设备地址所在区域的实时天气发布端口，并通过该终端设备地址所在区域的实时天气发布端口查询该终端设备地址对应的天气类型信息，作为该终端设备所在地的场景信息。例如来说，转发节点可以调用该终端设备地址所在区域的实时天气发布端口，并通过该终端设备地址所在区域的实时天气发布端口向该实时天气发布端口对应的天气服务器发送包括该终端设备地址的天气类型信息查收请求，以及接收该实时天气发布端口对应的天气服务器返回的该终端设备地址对应的天气类型信息，作为该终端设备所在地的场景信息。
作为一种优选的实施方式，转发节点调用该终端设备地址所在区域的实时天气发布端口之后，以及通过该终端设备地址所在区域的实时天气发布端口查询该终端设备地址对应的天气类型信息，作为该终端设备所在地的场景信息之前，转发节点还可以先执行以下步骤：
转发节点可以检测该终端设备地址所在区域的实时天气发布端口是否绑定有允许被查询天气类型信息的已签约终端设备的标识集合；
如果该终端设备地址所在区域的实时天气发布端口绑定有允许被查询天气类型信息的已签约终端设备的标识集合，查询已签约终端设备的标识集合中是否包括该终端设备地址所属终端设备的终端设备标识；
如果已签约终端设备的标识集合中包括该终端设备地址所属终端设备的终端设备标识，才执行通过该终端设备地址所在区域的实时天气发布端口查询该终端设备地址对应的天气类型信息，作为终端设备所在地的场景信息。
其中，实施上述步骤可以获取已签约终端设备的终端设备地址对应的天气类型信息作为终端设备所在地的场景信息，从而可以防止未签约终端设备的终端设备地址对应的天气类型信息发生泄露。
203、转发节点将每一终端设备发起的物联网数据和该终端设备所在地的场景信息一起封装成数据元上报给过滤网关。
在图1所示的物联网架构中，由于终端设备发起的物联网数据的信号量小，且独立的物联网数据的信号是非致命的，因此上述步骤203中转发节点可以对终端设备发起的物联网数据进行裁剪，并将裁剪得到的数据与该终端设备所在地的场景信息一起封装成数据元后直接或者间接上报给过滤网关。
204、过滤网关从各个转发节点上报的数据元中，确定出包括汇聚单元指定的场景信息的部分数据元。
本发明实施例中，过滤网关可以从各个转发节点上报的数据元中，确定出包括汇聚单元指定的天气类型信息(属于一种场景信息)的部分数据元。
205、过滤网关从确定出的部分数据元中确定出包括汇聚单元不感兴趣的终端设备类型的数据元作为待处理数据元。
本发明实施例中，过滤网关可以从确定出的部分数据元中确定出包括在汇聚单元指定的场景信息下无需上报物联网数据的终端设备类型的数据元，作为待处理数据元；其中，在汇聚单元指定的场景信息下无需上报物联网数据的终端设备类型即为汇聚单元不感兴趣的终端设备类型。
206、过滤网关从各个转发节点上报的数据元中过滤上述待处理数据元，并将剩余的数据元上报给汇聚单元。
207、汇聚单元对过滤网关上报的剩余数据元进行分析和决策进行分析和决策。
本发明实施例中，汇聚单元可以对过滤网关上报的剩余数据元进行分析和决策，从而可以为人们提供预警、异常等相关报告。
在图2所描述的基于场景信息的物联网数据智能过滤方法中，转发节点可以根据每一终端设备发起的物联网数据包括的终端设备标识，获取该终端设备的终端设备标识对应的终端设备地址；进一步地，转发节点还可以获取该终端设备地址对应的天气类型信息作为该终端设备所在地的场景信息；在此基础上，转发节点可以将每一终端设备发起的物联网数据和该终端设备所在地的场景信息一起封装成数据元上报给过滤网关，而过滤网关可以从各个转发节点上报的数据元中确定出包括汇聚单元指定的场景信息的部分数据元，以及从确定出的部分数据元中确定出包括汇聚单元不感兴趣的终端设备类型的数据元作为待处理数据元进行过滤，并将剩余的数据元上报给汇聚单元进行分析和决策。举例来说，汇聚单元指定的场景信息可以为雨天(属于一种天气类型信息)，而在雨天时汇聚单元不关注、不感兴趣的终端设备类型可以是农场部署的湿度感知终端设备(如湿度计)，因为农场部署的湿度感知终端设备上报的物联网数据对于汇聚单元来说，一般是在晴天(属于另一种天气类型信息)时才被汇聚单元关注和感兴趣的。所以，过滤网关可以从各个转发节点上报的数据元中确定出包括的场景信息为雨天(即汇聚单元指定的场景信息)的部分数据元，以及从确定出的部分数据元中确定出包括的终端设备类型为湿度感知终端设备(即汇聚单元不感兴趣的终端设备类型)的数据元作为待处理数据元进行过滤，并将剩余的数据元上报给汇聚单元进行分析和决策。可见，图2所描述的基于场景信息的物联网数据智能过滤方法可以有效的过滤掉汇聚单元不感兴趣的终端设备的数据，从而可以降低汇 聚单元的工作负荷。
实施例二
在图1所描述的物联网架构的基础上，本发明实施例公开了一种基于场景信息的物联网数据智能过滤方法。请参阅图3，图3是本发明实施例公开的另一种基于场景信息的物联网数据智能过滤方法的流程示意图。如图3所示，该基于场景信息的物联网数据智能过滤方法可以包括以下步骤：
301、过滤网关接收汇聚单元下发的过滤表，该过滤表包括汇聚单元指定的场景信息以及在汇聚单元指定的场景信息下无需上报物联网数据的终端设备类型。
举例来说，过滤网关接收到的汇聚单元下发的过滤表可以如表1所示，即：
表1过滤表

如表1所示，汇聚单元指定的场景信息可以包括汇聚单元指定的天气类型信息，当汇聚单元指定的天气类型信息为雨天时，在汇聚单元指定的场景信息下无需上报物联网数据的终端设备类型可以为农场部署的湿度感知终端设备(如湿度计)；当汇聚单元指定的天气类型信息为晴天时，在汇聚单元指定的场景信息下无需上报物联网数据的终端设备类型可以为雨量计；当汇聚单元指定的天气类型信息为台风天时，在汇聚单元指定的场景信息下无需上报物联网数据的终端设备类型可以为PM2.5检测仪。
302、转发节点接收其自身无线覆盖范围内的海量的终端设备发起的物联网数据；其中，每一终端设备发起的物联网数据包括终端设备标识、终端设备类型以及数据负载内容。
303、转发节点以每一终端设备发起的物联网数据包括的终端设备标识为依据，获取该终端设备的终端设备标识对应的终端设备地址；以及，获取该 终端设备地址对应的天气类型信息作为该终端设备所在地的场景信息。
作为一种可选的实施方式，上述步骤303中，转发节点获取该终端设备地址对应的天气类型信息作为该终端设备所在地的场景信息的方式可以为：
转发节点可以调用该终端设备地址所在区域的实时天气发布端口，并通过该终端设备地址所在区域的实时天气发布端口查询该终端设备地址对应的天气类型信息，作为该终端设备所在地的场景信息。例如来说，转发节点可以调用该终端设备地址所在区域的实时天气发布端口，并通过该终端设备地址所在区域的实时天气发布端口向该实时天气发布端口对应的天气服务器发送包括该终端设备地址的天气类型信息查收请求，以及接收该实时天气发布端口对应的天气服务器返回的该终端设备地址对应的天气类型信息，作为该终端设备所在地的场景信息。
作为一种优选的实施方式，转发节点调用该终端设备地址所在区域的实时天气发布端口之后，以及通过该终端设备地址所在区域的实时天气发布端口查询该终端设备地址对应的天气类型信息，作为该终端设备所在地的场景信息之前，转发节点还可以先执行以下步骤：
转发节点可以检测该终端设备地址所在区域的实时天气发布端口是否绑定有允许被查询天气类型信息的已签约终端设备的标识集合；
如果该终端设备地址所在区域的实时天气发布端口绑定有允许被查询天气类型信息的已签约终端设备的标识集合，查询已签约终端设备的标识集合中是否包括该终端设备地址所属终端设备的终端设备标识；
如果已签约终端设备的标识集合中包括该终端设备地址所属终端设备的终端设备标识，才执行通过该终端设备地址所在区域的实时天气发布端口查询该终端设备地址对应的天气类型信息，作为终端设备所在地的场景信息。
其中，实施上述步骤可以获取已签约终端设备的终端设备地址对应的天气类型信息作为终端设备所在地的场景信息，从而可以防止未签约终端设备的终端设备地址对应的天气类型信息发生泄露。
304、转发节点将每一终端设备发起的物联网数据和该终端设备所在地的场景信息一起封装成数据元上报给过滤网关。
305、过滤网关从各个转发节点上报的数据元中，确定出包括汇聚单元指定的场景信息的部分数据元。
本发明实施例中，过滤网关可以从各个转发节点上报的数据元中，确定出包括汇聚单元指定的天气类型信息(属于一种场景信息)的部分数据元。
306、过滤网关从确定出的部分数据元中确定出包括在汇聚单元指定的场景信息下无需上报物联网数据的终端设备类型的数据元，作为待处理数据元； 其中，在汇聚单元指定的场景信息下无需上报物联网数据的终端设备类型即为汇聚单元不感兴趣的终端设备类型。
307、过滤网关从各个转发节点上报的数据元中过滤上述待处理数据元，并将剩余的数据元上报给汇聚单元。
308、汇聚单元对过滤网关上报的剩余数据元进行分析和决策进行分析和决策。
举例来说，汇聚单元指定的场景信息可以为雨天(属于一种天气类型信息)，而在雨天时汇聚单元不关注、不感兴趣的终端设备类型可以是农场部署的湿度感知终端设备(如湿度计)，因为农场部署的湿度感知终端设备上报的物联网数据对于汇聚单元来说，一般是在晴天(属于另一种天气类型信息)时才被汇聚单元关注和感兴趣的。所以，过滤网关可以从各个转发节点上报的数据元中确定出包括的场景信息为雨天(即汇聚单元指定的场景信息)的部分数据元，以及从确定出的部分数据元中确定出包括的终端设备类型为湿度感知终端设备(即汇聚单元不感兴趣的终端设备类型)的数据元作为待处理数据元进行过滤，并将剩余的数据元上报给汇聚单元进行分析和决策。可见，图3所描述的基于场景信息的物联网数据智能过滤方法可以有效的过滤掉汇聚单元不感兴趣的终端设备的数据，从而可以降低汇聚单元的工作负荷。

本发明实施例中，可以获取已签约终端设备的终端设备地址对应的天气类型信息作为终端设备所在地的场景信息，从而可以防止未签约终端设备的终端设备地址对应的天气类型信息发生泄露。
作为一种可选的实施方式，在图4所示的基于场景信息的物联网数据智能过滤系统中：
过滤网关402，还用于在从各个转发节点上报的数据元中，确定出包括汇聚单元指定的场景信息的部分数据元之前，接收汇聚单元下发的过滤表，该过滤表包括汇聚单元403指定的场景信息以及在汇聚单元403指定的场景信息下无需上报物联网数据的终端设备类型；其中，汇聚单元403指定的场景信息包括汇聚单元403指定的天气类型信息，当汇聚单元403指定的天气类型信息包括雨天时，在汇聚单元403指定的场景信息下无需上报物联网数 据的终端设备类型包括农场部署的湿度感知终端设备；当汇聚单元403指定的天气类型信息包括晴天时，在汇聚单元403指定的场景信息下无需上报物联网数据的终端设备类型包括雨量计；当汇聚单元403指定的天气类型信息包括台风天时，在汇聚单元403指定的场景信息下无需上报物联网数据的终端设备类型包括PM2.5检测仪。

本发明实施例中，举例来说，汇聚单元指定的场景信息可以为雨天(属于一种天气类型信息)，而在雨天时汇聚单元不关注、不感兴趣的终端设备类型可以是农场部署的湿度感知终端设备(如湿度计)，因为农场部署的湿度感知终端设备上报的物联网数据对于汇聚单元来说，一般是在晴天(属于另一种天气类型信息)时才被汇聚单元关注和感兴趣的。所以，过滤网关可以从各个转发节点上报的数据元中确定出包括的场景信息为雨天(即汇聚单元指定的场景信息)的部分数据元，以及从确定出的部分数据元中确定出包括的终端设备类型为湿度感知终端设备(即汇聚单元不感兴趣的终端设备类型)的数据元作为待处理数据元进行过滤，并将剩余的数据元上报给汇聚单元进行分析和决策。可见，实施图4所示的系统，本发明实施例可以有效的过滤掉汇聚单元不感兴趣的终端设备的数据，从而可以降低汇聚单元的工作负荷。
