当其上报负荷大于等于第三负荷阈值时，路由节点将上述剩余物联网数据中包括的上述目标物联网数据封装成数据元，并将该数据元上报至汇聚单元。这样能够在路由节点的上报负荷较大时，只上报汇聚单元感兴趣的物联网数据，这样不仅能够缓解路由节点的上报压力，还能够提高成功上报汇聚单元感兴趣的物联网数据的可靠性。When the reported load is greater than or equal to the third load threshold, the routing node encapsulates the target Internet of Things data included in the remaining Internet of Things data into a data element, and reports the data element to the aggregation unit. In this way, when the reporting load of the routing node is large, only the IoT data of interest to the aggregation unit is reported, which not only can alleviate the reporting pressure of the routing node, but also improve the reliability of the IoT data that is successfully reported to the aggregation unit.
需要说明的是，每个物联网数据还可以包括上报该物联网数据的终端设备的地理位置，上述过滤指示消息还可以包括预设地理位置，且上述过滤指示消息可以具体用于指示路由节点针对该预设地理位置内的不同设备类型的终端设备上报的物联网数据中数据内容未处于与该设备类型的终端设备对应的预设数据范围内的物联网数据执行过滤操作。It should be noted that each of the Internet of Things data may further include a geographic location of the terminal device that reports the Internet of Things data, and the filtering indication message may further include a preset geographic location, and the filtering indication message may be specifically used to indicate that the routing node is The data content of the Internet of Things data reported by the terminal device of the different device types in the preset geographic location is not in the IoT data within the preset data range corresponding to the terminal device of the device type.

The IoT data with incorrect data content is filtered out, thereby reducing the reporting load of the routing node and the processing load of the aggregation unit.
