And the routing node identifies the to-be-filtered Internet of things data in the massive Internet of things data according to the filtering indication message, wherein the data content of any Internet of things data in the to-be-filtered Internet of things data is not in a preset data range corresponding to the terminal equipment reporting the Internet of things data.
In the embodiment of the present invention, specifically, the routing node may group the mass terminal devices according to the device types of the terminal devices to obtain terminal device groups of different device types, wherein the terminal devices belonging to the same terminal device group have the same device type, and the terminal devices belonging to different terminal device groups have different device types, and obtains the preset data range corresponding to the terminal device groups of different device types included in the filtering indication message, and identifying whether the data content in the internet of things data reported by each terminal device in the terminal device group of each device type is within a preset data range corresponding to the terminal device group of the device type, and if the data is not in the corresponding preset data range, the routing node determines that the corresponding Internet of things data is wrong Internet of things data, and determines all the wrong Internet of things data as the Internet of things data to be filtered.

Further optionally, the method for controlling filtering of data of the internet of things may further include the following operations:
when the remaining internet of things data does not include the target internet of things data, the routing node filters the remaining internet of things data, detects whether a reporting load of the routing node is smaller than or equal to a first preset load threshold value, monitors whether an adjacent routing node which needs to report the internet of things data and has the reporting load larger than or equal to a second preset load threshold value exists in a wireless coverage range of the routing node when the reporting load is smaller than or equal to the first preset load threshold value, and sends an idle prompt message to the adjacent routing node when the adjacent routing node exists, wherein the idle prompt message is used for prompting that the routing node is in an idle state, and the second preset load threshold value is larger than the first preset load threshold value.
The optional embodiment can encapsulate and report the rest internet of things data only when the rest networking data after filtering out the error internet of things data comprises the internet of things data interested by the aggregation unit, so that the reporting load of the routing node can be further reduced, and when the rest networking data does not comprise the internet of things data interested by the aggregation unit and the reporting load is small, the adjacent routing node which is in the wireless coverage range of the routing node and has a reporting requirement and a larger reporting load is informed, so that the adjacent routing node shares the reporting load by using the idle reporting resources, the utilization rate of the reporting resources can be improved, and the reporting pressure of the routing node can be balanced.
Further optionally, the reporting, by the routing node, the data element to the aggregation unit may include:
when the remaining internet of things data comprises the target internet of things data, the routing node determines the current time, determines a forwarding path with the highest priority from all forwarding paths corresponding to the time period to which the current time belongs according to pre-stored routing table configuration parameters, and reports the data element to the aggregation unit through the forwarding path with the highest priority, wherein the routing table configuration parameters comprise the priorities of a plurality of forwarding paths corresponding to different time periods, and the higher the priority is, the higher the reliability of the forwarding path is. Therefore, the reporting reliability of the internet of things data interested by the aggregation unit can be improved by selecting the forwarding path with higher priority for the data element of the internet of things data interested by the aggregation unit.
Further optionally, after recognizing that the remaining internet-of-things data includes the target internet-of-things data and before the routing node encapsulates the remaining internet-of-things data into data elements, the method for controlling filtering of internet-of-things data may further include the following operations:
the routing node detects whether the reported load is greater than or equal to a third load threshold, and when the reported load is not greater than or equal to the third load threshold, the operation of packaging the rest Internet of things data into data elements is triggered to be executed, wherein the third load threshold is greater than the first load threshold;
and when the reported load is greater than or equal to a third load threshold value, the routing node encapsulates the target internet of things data included in the residual internet of things data into a data element and reports the data element to the aggregation unit. Therefore, when the reporting load of the routing node is large, only the internet of things data interested by the aggregation unit is reported, so that the reporting pressure of the routing node can be relieved, and the reliability of successfully reporting the internet of things data interested by the aggregation unit can be improved.
It should be noted that each piece of internet-of-things data may further include a geographic location of a terminal device that reports the piece of internet-of-things data, 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 performs a filtering operation on the piece of internet-of-things data, in which data content in the piece of internet-of-things data reported by terminal devices of different device types in the preset geographic location is not in a preset data range corresponding to the terminal device of the device type.
It can be seen that, by implementing the method for controlling filtering of internet of things data described in fig. 2, the internet of things data whose data content is not within the corresponding preset data range can be filtered, that is, the internet of things data with wrong data content can be filtered from the massive internet of things data sensed by the routing node, so that the reporting load of the routing node and the processing load of the aggregation unit are reduced.
