发节点和过滤网关的双重数据过滤方法。请参阅图2，图2是本发明实施例公开的一种基于转发节点和过滤网关的双重数据过滤方法的流程示意图。如图2所示，该基于转发节点和过滤网关的双重数据过滤方法可以包括以下步骤：
201、过滤网关接收汇聚单元下发的第一过滤表，该第一过滤表包括汇聚单元只感兴趣的位置信息。
本发明实施例中，汇聚单元只感兴趣的位置信息可以是一个区域位置信息，例如某一农场的位置信息；或者，汇聚单元只感兴趣的位置信息也可以是一个具体的地理坐标位置信息，例如某一农场中的某一个湿度计的地理坐标位置信息。
202、转发节点接收海量的终端设备发起的物联网数据，该物联网数据包括终端设备类型、终端设备地址及数据内容。
本发明实施例中，转发节点可以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，终端设备类型用于表示终端设备的类别和型号，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。
203、转发节点在识别出任一终端设备上报的物联网数据包括汇聚单元指定的终端类型时，获取该终端设备的终端设备地址对应的实时天气类型。
作为一种可选的实施方式，上述步骤203中，转发节点在识别出任一终端设备上报的物联网数据包括汇聚单元指定的终端类型时，获取该终端设备的终端设备地址对应的实时天气类型的方式可以为：
转发节点在识别出任一终端设备上报的物联网数据包括汇聚单元指定的终端类型时，可以查询该终端设备上报的物联网数据包括的终端设备地址所在区域的实时天气发布服务器，并向该终端设备地址所在区域的实时天气发布服务器请求该终端设备地址对应的实时天气类型。
本发明实施例中，转发节点可以存储多个终端设备地址，其中，每一个终端设备地址分别与该终端设备地址所在区域的实时天气发布服务器的地址相对应。转发节点存储的多个终端设备地址不仅可以包括其自身无线覆盖范围内终端设备的终端设备地址，还可以包括相邻转发节点无线覆盖范围内终端设备的终端设备地址，本发明实施例不作限定。
作为一种可选的实施方式，上述的转发节点在识别出任一终端设备上报的物联网数据包括汇聚单元指定的终端类型时，查询该终端设备上报的物联
网数据包括的该终端设备地址所在区域的实时天气发布服务器的方式具体可以为：

作为一种可选的实施方式，转发节点在查询出该终端设备上报的物联网数据包括的该终端设备地址所在区域的实时天气发布服务器之后，以及向该终端设备地址所在区域的实时天气发布服务器请求该终端设备地址对应的实时天气类型之前，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服务器是否配置有允许被查询天气类型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服务器配置有允许被查询天气类型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，才执行向该终端设备地址所在区域的实时天气发布服务器请求该终端设备地址对应的实时天气类型的步骤。
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，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发生泄露。
204、转发节点在识别出该终端设备地址对应的实时天气类型与汇聚单元指定的天气类型不匹配时，过滤掉该终端设备发起的物联网数据，并将剩余的终端设备发起的物联网数据封装成数据元之后上报给过滤网关。
举例来说，转发节点在识别出该终端设备地址对应的实时天气类型“雨天”与汇聚单元指定的天气类型“晴天”不匹配时，转发节点可以过滤掉该终端设备发起的物联网数据，这样剩余的终端设备发起的物联网数据包括的终端设备类型均与汇聚单元指定的终端设备类型匹配，而且剩余的终端设备发起的物联网数据包括的终端设备地址对应的实时天气类型均与汇聚单元指定的天气类型匹配，此时转发节点可以将剩余的终端设备发起的物联网数据
封装成数据元之后上报给过滤网关。
205、过滤网关从各个转发节点上报的数据元中，确定出包含与汇聚单元只感兴趣的位置信息相匹配的终端设备地址的数据元，作为待上报数据元。
本发明实施例中，与汇聚单元只感兴趣的位置信息相匹配的终端设备地址的数据元是指：数据元包含的终端设备地址位于汇聚单元只感兴趣的位置信息内，或者，数据元包含的终端设备地址与汇聚单元只感兴趣的位置信息重叠，本发明实施例不作限定。
206、过滤网关将确定出的待上报数据元上报给汇聚单元。
207、汇聚单元对过滤网关上报的待上报数据元进行分析和决策。
本发明实施例中，汇聚单元可以对过滤网关上报的待上报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所描述的基于转发节点和过滤网关的双重数据过滤方法，转发节点可以接收海量的终端设备发起的物联网数据，物联网数据包括终端设备类型、终端设备地址及数据内容；以及，转发节点在识别出任一终端设备上报的物联网数据包括汇聚单元指定的终端类型时，可以获取该终端设备的终端设备地址对应的实时天气类型，并在识别出该终端设备地址对应的实时天气类型与汇聚单元指定的天气类型不匹配时，过滤掉该终端设备发起的物联网数据，并将剩余的终端设备发起的物联网数据封装成数据元之后上报给过滤网关；过滤网关可以从各个转发节点上报的数据元中，确定出包含与汇聚单元只感兴趣的位置信息相匹配的终端设备地址的数据元作为待上报数据元上报给汇聚单元进行分析和决策。举例来说，汇聚单元指定的终端类型为农场部署的湿度感知终端设备(如湿度计)，并且汇聚单元指定的天气类型为晴天(属于一种天气类型)，其中，农场部署的湿度感知终端设备(如湿度计)被允许在晴天上报数据；当转发节点在识别出任一终端设备上报的物联网数据包括的汇聚单元指定的终端类型为湿度感知终端设备(如湿度计)时，转发节点可以获取该终端设备上报的物联网数据包括的终端设备地址对应的实时天气类型，并在识别出该终端设备地址对应的实时天气类型与晴天(晴天为汇聚单元指定的天气类型)不匹配时，过滤掉该终端设备发起的物联网数据，这样剩余的终端设备发起的物联网数据包括的汇聚单元指定的终端类型均为湿度感知终端设备(如湿度计)，且剩余的终端设备发起的物联网数据包括的终端设备地址对应的实时天气类型均与晴天(晴天为汇聚单元指定的天气类型)匹配，此时转发节点可以将剩余的终端设备发起的物联网数据封装成数据元之后上报给过滤网关，过滤网关可以从各个转发节点上报的数据元中，确定出包含与汇聚单元只感兴趣的位置信息相匹配的终端设备地址的
数据元作为待上报数据元上报给汇聚单元进行分析和决策。可见，实施图2所描述的基于转发节点和过滤网关的双重数据过滤方法，本发明实施例可以基于转发节点和过滤网关实现双重数据过滤，从而可以有效的降低汇聚单元的工作负担，而且还可以提高汇聚单元获得感兴趣的终端设备数据的精度。

举例来说，转发节点接收到的汇聚单元通过过滤网关下发的第二过滤表可以如表1所示，即：
表1第二过滤表
如表1所示，当汇聚单元指定的终端设备类型为雨量计时，汇聚单元指定的天气类型可以为雨天，因为汇聚单元在雨天时一般才对雨量计上报的物联网数据(即降雨量)感兴趣；当汇聚单元指定的终端设备类型为湿度感知终端设备(如湿度计)时，汇聚单元指定的天气类型可以为晴天，因为汇聚单元在晴天时一般才对湿度感知终端设备(如湿度计)上报的物联网数据(即
土壤容积含水量)感兴趣；当汇聚单元指定的终端设备类型为PM2.5检测仪时，汇聚单元指定的天气类型可以为雾霾天，因为汇聚单元在雾霾天时一般才对PM2.5检测仪上报的物联网数据(PM2.5值)感兴趣。
303、转发节点接收海量的终端设备发起的物联网数据，该物联网数据包括终端设备类型、终端设备地址及数据内容。
304、转发节点在识别出任一终端设备上报的物联网数据包括第二过滤表中汇聚单元指定的终端类型时，获取该终端设备的终端设备地址对应的实时天气类型。
作为一种可选的实施方式，上述步骤304中，转发节点在识别出任一终端设备上报的物联网数据包括汇聚单元指定的终端类型时，获取该终端设备的终端设备地址对应的实时天气类型的方式可以为：
转发节点在识别出任一终端设备上报的物联网数据包括汇聚单元指定的终端类型时，可以查询该终端设备上报的物联网数据包括的终端设备地址所在区域的实时天气发布服务器，并向该终端设备地址所在区域的实时天气发布服务器请求该终端设备地址对应的实时天气类型。
本发明实施例中，转发节点可以存储多个终端设备地址，其中，每一个终端设备地址分别与该终端设备地址所在区域的实时天气发布服务器的地址相对应。转发节点存储的多个终端设备地址不仅可以包括其自身无线覆盖范围内终端设备的终端设备地址，还可以包括相邻转发节点无线覆盖范围内终端设备的终端设备地址，本发明实施例不作限定。
作为一种可选的实施方式，上述的转发节点在识别出任一终端设备上报的物联网数据包括汇聚单元指定的终端类型时，查询该终端设备上报的物联网数据包括的该终端设备地址所在区域的实时天气发布服务器的方式具体可以为：
转发节点在识别出任一终端设备上报的物联网数据包括汇聚单元指定的终端类型时，可以检测该转发节点是否被配置用于查询实时天气发布服务器的时间段，如果该转发节点被配置用于查询实时天气发布服务器的时间段，判断该转发节点的当前系统时间是否位于该时间段内，如果是，查询该终端设备上报的物联网数据包括的该终端设备地址所在区域的实时天气发布服务器。其中，实施这种实施方式可以避免转发节点频繁地查询终端设备地址所在区域的实时天气发布服务器，从而可以降低转发节点查询终端设备地址所在区域的实时天气发布服务器时导致的功耗。
作为一种可选的实施方式，转发节点在查询出该终端设备上报的物联网数据包括的该终端设备地址所在区域的实时天气发布服务器之后，以及向该终端设备地址所在区域的实时天气发布服务器请求该终端设备地址对应的实时天气类型之前，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服务器是否配置有允许被查询天气类型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服务器配置有允许被查询天气类型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，才执行向该终端设备地址所在区域的实时天气发布服务器请求该终端设备地址对应的实时天气类型的步骤。
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，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发生泄露。
305、转发节点在识别出该终端设备地址对应的实时天气类型与第二过滤表中汇聚单元指定的天气类型不匹配时，过滤掉该终端设备发起的物联网数据，并将剩余的终端设备发起的物联网数据封装成数据元之后上报给过滤网关。
举例来说，转发节点在识别出该终端设备地址对应的实时天气类型“雨天”与汇聚单元指定的天气类型“晴天”不匹配时，转发节点可以过滤掉该终端设备发起的物联网数据，这样剩余的终端设备发起的物联网数据包括的终端设备类型均与汇聚单元指定的终端设备类型匹配，而且剩余的终端设备发起的物联网数据包括的终端设备地址对应的实时天气类型均与汇聚单元指定的天气类型匹配，此时转发节点可以将剩余的终端设备发起的物联网数据封装成数据元之后上报给过滤网关。
306、过滤网关从各个转发节点上报的数据元中，确定出包含与第一过滤表中汇聚单元只感兴趣的位置信息相匹配的终端设备地址的数据元，作为待上报数据元。
本发明实施例中，与汇聚单元只感兴趣的位置信息相匹配的终端设备地址的数据元是指：数据元包含的终端设备地址位于汇聚单元只感兴趣的位置信息内，或者，数据元包含的终端设备地址与汇聚单元只感兴趣的位置信息重叠，本发明实施例不作限定。
307、过滤网关将确定出的待上报数据元上报给汇聚单元。
308、汇聚单元对过滤网关上报的待上报数据元进行分析和决策。
本发明实施例中，汇聚单元可以对过滤网关上报的待上报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。
举例来说，汇聚单元指定的终端类型为农场部署的湿度感知终端设备(如
湿度计)，并且汇聚单元指定的天气类型为晴天(属于一种天气类型)，其中，农场部署的湿度感知终端设备(如湿度计)被允许在晴天上报数据；当转发节点在识别出任一终端设备上报的物联网数据包括的汇聚单元指定的终端类型为湿度感知终端设备(如湿度计)时，转发节点可以获取该终端设备上报的物联网数据包括的终端设备地址对应的实时天气类型，并在识别出该终端设备地址对应的实时天气类型与晴天(晴天为汇聚单元指定的天气类型)不匹配时，过滤掉该终端设备发起的物联网数据，这样剩余的终端设备发起的物联网数据包括的汇聚单元指定的终端类型均为湿度感知终端设备(如湿度计)，且剩余的终端设备发起的物联网数据包括的终端设备地址对应的实时天气类型均与晴天(晴天为汇聚单元指定的天气类型)匹配，此时转发节点可以将剩余的终端设备发起的物联网数据封装成数据元之后上报给过滤网关，过滤网关可以从各个转发节点上报的数据元中，确定出包含与汇聚单元只感兴趣的位置信息相匹配的终端设备地址的数据元作为待上报数据元上报给汇聚单元进行分析和决策。可见，实施图3所描述的基于转发节点和过滤网关的双重数据过滤方法，本发明实施例可以基于转发节点和过滤网关实现双重数据过滤，从而可以有效的降低汇聚单元的工作负担，而且还可以提高汇聚单元获得感兴趣的终端设备数据的精度。
