202. The edge routing node monitors massive Internet of things data reported by massive terminal equipment in a wireless coverage range of the edge routing node, wherein each Internet of things data comprises an equipment type of the terminal equipment reporting the Internet of things data, data content collected by the terminal equipment and an equipment identifier where the terminal equipment is located.

203. When multiple pieces of internet of things data exist in the massive amounts of internet of things data, wherein the device identifiers of the terminal devices are not stored in a pre-generated routing information table, the edge routing node judges whether at least one piece of internet of things data, of which the device type of the terminal device is the target device type, exists in the multiple pieces of internet of things data, and when the judgment result in the step 203 is yes, the step 204 is triggered to be executed, and when the judgment result in the step 203 is no, the step 205 is triggered to be executed.
In the embodiment of the present invention, the routing information table stores the device identifier of the terminal device in the wireless coverage area of the edge routing node, and may also store the IP address of the terminal device in the wireless coverage area.
204. And the edge routing node adds the equipment identifier of the terminal equipment included in the at least one piece of data of the internet of things to the routing information table.
205. The edge routing node controls not to update the routing information table.

As shown in fig. 3, the method for controlling the edge routing node to update the routing information table may include the following operations:
301. and the edge routing node receives an indication message which is issued by the filtering gateway and used for indicating that the aggregation unit is interested in the data of the Internet of things reported by the terminal equipment of the target equipment type.
In the embodiment of the present invention, the terminal devices in the architecture of the internet of things may be divided into terminal devices of different device types according to the functions of the terminal devices, or may be divided into terminal devices of different device types according to the device models of the terminal devices, which is not limited in the embodiment of the present invention.
302. The edge routing node monitors massive Internet of things data reported by massive terminal equipment in a wireless coverage range of the edge routing node, wherein each Internet of things data comprises an equipment type of the terminal equipment reporting the Internet of things data, data content collected by the terminal equipment and an equipment identifier where the terminal equipment is located.
303. When multiple pieces of internet of things data exist in the massive amounts of internet of things data, wherein the device identifiers of the terminal devices are not stored in a pre-generated routing information table, the edge routing node judges whether at least one piece of internet of things data, of which the device type of the terminal device is the target device type, exists in the multiple pieces of internet of things data, if the judgment result in the step 303 is yes, the step 304 is triggered to be executed, and if the judgment result in the step 303 is no, the step 307 is triggered to be executed.
304. The edge routing node determines whether there is a terminal device passing through the terminal device reporting the at least one piece of internet of things data, and if the determination result in step 304 is no, triggers execution of step 305, and if the determination result in step 304 is yes, triggers execution of step 306.
In this embodiment of the present invention, the determining, by the edge routing node, whether there is a terminal device that passes through the edge routing node among the terminal devices that report the at least one piece of internet-of-things data may include:

305. And the edge routing node adds the equipment identifier of the terminal equipment included in the at least one piece of data of the internet of things to the routing information table.
306. And the edge routing node adds the device identification of the terminal device except the terminal device passing by in the terminal device reporting the data of the at least one internet of things to the routing information table.
307. The edge routing node controls not to update the routing information table.
In an optional embodiment, the method for controlling the edge routing node to update the routing information table may further include the following operations:
the edge routing node judges whether an equipment identifier of an offline terminal equipment exists in the routing information table or not, and deletes the equipment identifier of the offline terminal equipment from the routing information table when the equipment identifier of the offline terminal equipment exists, wherein the offline terminal equipment is terminal equipment which does not report internet of things data to the edge routing node within a preset time period or terminal equipment which reports the internet of things data to the edge routing node and has a reporting frequency lower than a preset frequency threshold, and the offline terminal equipment can comprise damaged terminal equipment and/or terminal equipment which is in a long-time closed state and/or terminal equipment of which the equipment identifier is added to a routing information table of an adjacent routing node.
The optional embodiment can delete the device identifier of the terminal device which is offline from the routing information table in time, and is beneficial to the instant update of the topology structure of the internet of things in the architecture of the internet of things.
In another optional embodiment, the method for controlling the edge routing node to update the routing information table may further include the following operations:
and the edge routing node counts the reporting frequency of the data of the internet of things reported by the target terminal equipment of which the equipment type is the target equipment type in all the terminal equipment corresponding to the equipment identification stored in the routing information table, and sends a reporting frequency up-regulation instruction to the terminal equipment of which the reporting frequency is lower than a preset reporting frequency threshold value in the target terminal equipment. Therefore, the reliability of the data of the internet of things, which are reported by the terminal equipment of the geographical position in which the convergence unit is interested, received by the convergence unit can be improved.
In this alternative embodiment, further optionally, the method for controlling the edge routing node to update the routing information table may further include the following operations:
and the edge routing node sets a reporting priority for the equipment identifier of the terminal equipment with the reporting frequency lower than the preset reporting frequency threshold value in the target terminal equipment in the routing information table, wherein the smaller the reporting frequency is, the larger the set reporting priority is. Therefore, when the internet of things data reported by the terminal equipment with lower reporting frequency is received, the part of the internet of things data can be reported preferentially according to the set priority or the forwarding path with higher reliability can be selected preferentially for the part of the internet of things data, and the reliability of the convergence unit receiving the internet of things data reported by the terminal equipment with lower reporting frequency and interest in the convergence unit is further improved.
