201. and the edge routing node receives the indication information sent by the aggregation unit through the filter gateway, wherein the indication information comprises the position area which is interested by the aggregation unit.
In the embodiment of the present invention, the location area in which the convergence unit is interested may be an area, such as a location area of a certain farm; alternatively, the location of interest to the convergence unit may be a specific geographical coordinate location, such as the geographical coordinate location of a hygrometer in a farm.
In the embodiment of the invention, the edge routing node can detect whether the load of a communication port between the edge routing node and the convergence unit exceeds the standard or not, if not, the edge routing node can send an indication information acquisition request to the convergence node, wherein the indication information acquisition request comprises the identity of the edge routing node; correspondingly, the sink node can identify whether the identity of the edge routing node belongs to the identity of a legal routing node, and if so, the sink node issues indication information to the edge routing node.
202. The edge routing node monitors massive Internet of things data initiated by the terminal equipment, wherein the Internet of things data comprises terminal equipment identification, terminal equipment position and data content.

203. The edge routing node judges whether the position of the terminal equipment, which is included in the data of the internet of things initiated by the terminal equipment, is matched with the position area interested by the convergence unit or not aiming at each terminal equipment, and if the position of the terminal equipment is matched with the position area interested by the convergence unit, the process is ended; if not, step 204 is performed.
In the embodiment of the present invention, the matching between the location of the terminal device included in the data of the internet of things initiated by the terminal device and the location area interested by the aggregation unit means: the location of the terminal device included in the data of the internet of things initiated by the terminal device is located in the location area interested by the aggregation unit, or the location of the terminal device included in the data of the internet of things initiated by the terminal device is overlapped with the location area interested by the aggregation unit.
204. And the edge routing node sends a reporting frequency down-regulation instruction to the terminal equipment to which the terminal equipment identifier included in the data of the internet of things initiated by the terminal equipment belongs, so that the terminal equipment can down-regulate the current reporting frequency of the terminal equipment according to the reporting frequency down-regulation instruction.

306. The edge routing node judges whether the position of the terminal equipment, which is included in the data of the internet of things initiated by the terminal equipment, is matched with the position area interested by the convergence unit or not aiming at each terminal equipment, and if the position of the terminal equipment is matched with the position area interested by the convergence unit, the process is ended; if not, go to step 307-step 308.

As an optional implementation manner, when determining that a target node exists around the edge routing node, the edge routing node may determine whether a distance between the edge routing node and the target node is smaller than a preset threshold, and if so, the edge routing node initiates an instant weather type query request including a terminal device location included in the internet of things data initiated by the terminal device to the target node, so that the edge routing node may query an instant weather type including the terminal device location included in the internet of things data initiated by the terminal device as soon as possible.
As an optional implementation manner, after the edge routing node determines that the total number of the terminal devices initiating the data of the internet of things in the wireless coverage area of the edge routing node does not exceed the preset number specified by the edge routing node, and before the edge routing node initiates an instant weather type query request including the terminal device position included in the data of the internet of things initiated by the terminal device to the cloud service platform corresponding to the weather information query port through the weather information query port, the edge routing node may further perform the following steps:
the method comprises the steps that an edge routing node identifies and detects whether the edge routing node is configured with a time period allowing access to a cloud service platform, and if the edge routing node is configured with the time period allowing access to the cloud service platform, whether the current system time of the edge routing node is within the time period is judged;
if the current system time of the edge routing node is within the time period, the edge routing node can detect whether the cloud service platform is configured with an identification set of signed terminal equipment or not; and if the terminal equipment identification set comprises the terminal equipment identification of the terminal equipment position contained in the Internet of things data initiated by the terminal equipment, initiating an instant weather type query request comprising the terminal equipment position contained in the Internet of things data initiated by the terminal equipment to the cloud service platform corresponding to the weather information query port through the weather information query port.
By implementing the implementation mode, the edge routing node can be prevented from frequently inquiring the instant weather type of the terminal equipment position, so that the power consumption caused when the edge routing node inquires the instant weather type of the terminal equipment position can be reduced.
The steps can be implemented to obtain the instant weather type of the terminal device position of the signed terminal device, so that the instant weather type of the terminal device position of the terminal device which is not signed can be prevented from being leaked.
308. The edge routing node judges whether the instant weather type corresponding to the position of the terminal equipment is consistent with the weather type which is interested by the convergence unit, if so, the process is ended; if not, go to step 309.
309. And the edge routing node sends a reporting frequency down-regulation instruction comprising the assigned reporting frequency distributed for the terminal equipment to which the terminal equipment identifier included in the data of the internet of things initiated by the terminal equipment belongs, so that the terminal equipment can down-regulate the current reporting frequency of the terminal equipment according to the reporting frequency down-regulation instruction.
In the embodiment of the invention, the edge routing nodes can package the data of the internet of things initiated by the terminal equipment into data elements and report the data elements to the filtering gateway, and the filtering gateway determines the data elements containing the terminal equipment positions matched with the position information only interested by the convergence unit from the data elements reported by each edge routing node and reports the data elements to the convergence unit for analysis and decision.
In the embodiment of the invention, the aggregation unit can analyze and decide the data elements to be reported, which are reported by the filter gateway, so that relevant reports such as early warning, abnormity and the like can be provided for people.
As can be seen, the method described in fig. 3 can reduce the data reporting frequency of the internet of things of the terminal device located outside the location area of interest of the aggregation unit by using the edge routing node, thereby reducing the occurrence probability of network congestion and the workload of the aggregation unit.
