Referring to fig. 2, fig. 2 is a flow chart of a method for controlling the data reporting frequency of the internet of things of a terminal device according to an embodiment of the present invention. As shown in fig. 2, the method for controlling the data reporting frequency of the internet of things of the terminal device may include the following steps:
201. the filtering gateway receives forwarding node indication information sent by the aggregation unit, wherein the forwarding node indication information comprises weather types and terminal equipment types which are interested in the aggregation unit.
In the embodiment of the invention, the weather types of interest of the convergence unit can comprise various weather types such as rainy days, sunny days, haze days, typhoon days and the like; the terminal equipment type of interest of the convergence unit is used for indicating the type and model of the terminal equipment of interest of the convergence unit, wherein the type of the terminal equipment can comprise various terminal equipment such as a rain gauge, a hygrometer, an irrigation valve and the like, and the embodiment of the invention is not limited.
202. The filtering gateway transmits the forwarding node indication information to the forwarding node.
In the embodiment of the invention, the filtering gateway can step by step transmit the forwarding node indication information to each forwarding node.
203. The forwarding node stores forwarding node indication information issued by the filtering gateway.
204. The forwarding node detects massive Internet of things data initiated by terminal equipment in a wireless coverage range, wherein the Internet of things data comprises terminal equipment types, terminal equipment addresses and data contents.
In the embodiment of the present invention, the address of the terminal device may be a geographic coordinate address of the terminal device, or may be a network address (such as an IP address) of the terminal device, which is not limited in the embodiment of the present invention; the data content is used for representing a data load reported by the terminal equipment, for example, the data of the internet of things reported by the humidity sensing terminal equipment deployed on the farm comprises the water content of the soil volume; for another example, the data content of the internet of things reported by the temperature sensor may be a temperature value; for another example, the internet of things data reported by the rain gauge may include a rainfall.
205. The forwarding node identifies whether the terminal equipment type contained in the internet of things data initiated by the terminal equipment accords with the terminal equipment type interested by the convergence unit according to each terminal equipment, and if so, inquires the instant weather type corresponding to the terminal equipment address contained in the internet of things data initiated by the terminal equipment through the weather information inquiry port.
In the embodiment of the invention, when the forwarding node identifies that the type of the terminal equipment contained in the data of the internet of things initiated by the terminal equipment is inconsistent with the type of the terminal equipment interested by the convergence unit, the data packet of the internet of things initiated by the terminal equipment can be filtered. For example, when the forwarding node identifies that the type of the terminal device included in the data of the internet of things initiated by the terminal device is a "rain gauge" and the type of the terminal device interested by the aggregation unit is a "hygrometer", the forwarding node may identify that the type of the terminal device included in the data of the internet of things initiated by the terminal device does not coincide with the type of the terminal device interested by the aggregation unit, and the forwarding node may filter the data packet of the internet of things initiated by the terminal device.
As another optional implementation manner, in step 205, when the forwarding node recognizes that the terminal device type included in the data of the internet of things initiated by the terminal device does not match the terminal device type interested in the convergence unit, the forwarding node may directly perform step 206.
206. The forwarding node identifies whether the instant weather type corresponding to the terminal equipment address accords with the terminal equipment type interested by the convergence unit, and if not, the forwarding node sends a data reporting frequency down-regulating instruction to the terminal equipment.
207. And the terminal equipment downwards regulates the data reporting frequency of the Internet of things according to the reporting frequency downwards regulating instruction.

As an optional implementation manner, in step 205, a manner in which the forwarding node queries, through the weather information query port, the instant weather type corresponding to the terminal device address included in the internet of things data initiated by the terminal device may be:
the forwarding node judges whether the total number of terminal devices initiating the data of the internet of things at the same time within the wireless coverage range of the forwarding node exceeds the preset number appointed by the forwarding node; the preset number designated by each forwarding node may be different, which is not limited in the embodiment of the present invention;
if the total number does not exceed the preset number designated by the forwarding node, the forwarding node can initiate an instant weather type query request comprising a terminal equipment address contained in the internet of things data initiated by the terminal equipment to a cloud service platform corresponding to the weather information query port through the weather information query port; the forwarding node can receive an instant weather type corresponding to the terminal equipment address returned by the cloud service platform through the weather information query port;
Or if the total number exceeds the preset number designated by the forwarding node, the forwarding node can determine whether a target node exists around the forwarding node, wherein the total number of terminal devices which initiate the data of the internet of things in the wireless coverage area of the target node is minimum and does not exceed the preset number designated by the target node; if the target node exists, the forwarding node can initiate an instant weather type query request comprising a terminal equipment address contained in the internet of things data initiated by the terminal equipment to the target node, so that the target node initiates the instant weather type query request to a cloud service platform corresponding to the weather information query port, and the cloud service platform returns the instant weather type corresponding to the terminal equipment address to the target node through the weather information query port; and the forwarding node receives the instant weather type corresponding to the terminal equipment address sent by the target node.
As an optional implementation manner, when the forwarding node determines that the target node exists around the forwarding node, the forwarding node may determine whether the distance between the forwarding node and the target node is smaller than a preset threshold, if so, the forwarding node initiates an instant weather type query request including a terminal device address included in the internet of things data initiated by the terminal device to the target node, so that the forwarding node can query an instant weather type of the terminal device address included in the internet of things data initiated by the terminal device as soon as possible.
As an optional implementation manner, after the forwarding node determines that the total number of terminal devices initiating the data of the internet of things at the same time within the wireless coverage area of the forwarding node exceeds the preset number specified by the forwarding node, and before the forwarding node initiates an instant weather type query request including a terminal device address included in the data of the internet of things initiated by the terminal device to a cloud service platform corresponding to the weather information query port through the weather information query port, the forwarding node may further perform the following steps:
the forwarding node identifies and detects whether the forwarding node is configured with a time period allowing access to the cloud service platform, and if the forwarding node is configured with the time period allowing access to the cloud service platform, the forwarding node judges whether the current system time of the forwarding node is within the time period;
if the current system time of the forwarding node is within the time period, the forwarding node can detect whether the cloud service platform is configured with an identification set of the signed terminal equipment or not; if the cloud service platform is configured with the identification set of the signed terminal equipment, inquiring whether the identification set of the signed terminal equipment comprises the terminal equipment identification of the terminal equipment to which the terminal equipment address contained in the internet of things data initiated by the terminal equipment belongs, and if so, initiating an instant weather type inquiry request comprising the terminal equipment address contained in the internet of things data initiated by the terminal equipment to the cloud service platform corresponding to the weather information inquiry port through the weather information inquiry port.
The implementation of the embodiment can avoid that the forwarding node frequently inquires the instant weather type of the terminal equipment address, so that the power consumption caused when the forwarding node inquires the instant weather type of the terminal equipment address can be reduced.
The implementation of the steps can acquire the instant weather type of the terminal equipment address of the signed terminal equipment, so that the instant weather type of the terminal equipment address of the unsigned terminal equipment can be prevented from being leaked.
In the embodiment of the invention, the forwarding node can encapsulate the data of the internet of things initiated by the terminal equipment into the data elements and report the data elements to the filtering gateway, and the filtering gateway determines the data elements containing the terminal equipment addresses matched with the position information only interested by the aggregation unit from the data elements reported by the forwarding nodes and reports the data elements to the aggregation 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 filtering gateway, so that related reports such as early warning, abnormality and the like can be provided for people.
In the control method of the data reporting frequency of the internet of things of the terminal equipment described in fig. 1, a forwarding node receives forwarding node indication information including weather types interested by the aggregation unit and terminal equipment types issued by the aggregation unit through a filtering gateway; and the forwarding node monitors massive Internet of things data initiated by terminal equipment in a wireless coverage range, when the terminal equipment type contained in the Internet of things data initiated by a certain terminal equipment is identified to be consistent with the interesting terminal equipment type, the instant weather type corresponding to the terminal equipment address contained in the Internet of things data initiated by the terminal equipment is queried through the weather information query port, when the instant weather type is identified to be consistent with the interesting terminal equipment type, a data reporting frequency down regulation instruction is sent to the terminal equipment, and the terminal equipment down regulates the Internet of things data reporting frequency. Therefore, the control method described in fig. 1 can flexibly adjust the data reporting frequency of the terminal device that is not interested in the aggregation unit, so as to reduce the workload of the aggregation unit and reduce the occurrence probability of network congestion.

table 1 forwarding node indication information
As shown in table 1, when the weather type of interest of the convergence unit is rainy days, the terminal device type of interest of the convergence unit may be a rain gauge, because the convergence unit is generally interested in internet of things data (i.e., rainfall) reported by the rain gauge in rainy days; when the weather type of interest of the aggregation unit is sunny, the terminal equipment type of interest of the aggregation unit can be humidity sensing terminal equipment (such as a hygrometer), because the aggregation unit is generally interested in the internet of things data (namely the water content of the soil volume) reported by the humidity sensing terminal equipment (such as the hygrometer) on sunny days; when the weather type of interest of the convergence unit is a haze day, the terminal equipment type of interest of the convergence unit may be a PM2.5 detector, because the convergence unit is generally interested in internet of things data (PM 2.5 values) reported by the PM2.5 detector only when the convergence unit is in the haze day.
302. The filtering gateway transmits the forwarding node indication information to the forwarding node.
In the embodiment of the invention, the filtering gateway can step by step transmit the forwarding node indication information to each forwarding node.
303. The forwarding node detects whether the terminal equipment types of part of terminal equipment in mass terminal equipment in the wireless coverage range of the forwarding node are matched with the terminal equipment types interested by the convergence unit, and if so, the forwarding node indication information issued by the filtering gateway is stored.
In the embodiment of the invention, if the terminal equipment types of the mass terminal equipment which does not exist part of the terminal equipment in the wireless coverage range of the forwarding node are detected to be matched with the terminal equipment types which are interested by the aggregation unit, the forwarding node can delete the forwarding node indication information which is issued by the filtering gateway.
304. The forwarding node detects massive Internet of things data initiated by terminal equipment in a wireless coverage range, wherein the Internet of things data comprises terminal equipment types, terminal equipment addresses and data contents.

305. The forwarding node identifies whether the terminal equipment type contained in the internet of things data initiated by the terminal equipment accords with the terminal equipment type interested by the convergence unit according to each terminal equipment, and if so, inquires the instant weather type corresponding to the terminal equipment address contained in the internet of things data initiated by the terminal equipment through the weather information inquiry port.
In the embodiment of the invention, when the forwarding node identifies that the type of the terminal equipment contained in the data of the internet of things initiated by the terminal equipment is inconsistent with the type of the terminal equipment interested by the convergence unit, the data packet of the internet of things initiated by the terminal equipment can be filtered. For example, when the forwarding node identifies that the type of the terminal device included in the data of the internet of things initiated by the terminal device is a "rain gauge" and the type of the terminal device interested by the aggregation unit is a "hygrometer", the forwarding node may identify that the type of the terminal device included in the data of the internet of things initiated by the terminal device does not coincide with the type of the terminal device interested by the aggregation unit, and the forwarding node may filter the data packet of the internet of things initiated by the terminal device.
As another optional implementation manner, in step 305, when the forwarding node recognizes that the terminal device type included in the data of the internet of things initiated by the terminal device does not match the terminal device type interested in the convergence unit, the forwarding node may directly perform step 306.
306. The forwarding node identifies whether the instant weather type corresponding to the terminal equipment address accords with the terminal equipment type interested by the convergence unit, and if not, the forwarding node sends a data reporting frequency down-regulating instruction to the terminal equipment.
307. And the terminal equipment downwards regulates the data reporting frequency of the Internet of things according to the reporting frequency downwards regulating instruction.
In the embodiment of the present invention, the report frequency down-regulating instruction may include a designated report frequency assigned by the forwarding node and lower than the current report frequency of the terminal device, so that the terminal device may update the current report frequency to the designated report frequency.
As an optional implementation manner, in the step 305, the manner in which the forwarding node queries, through the weather information query port, the instant weather type corresponding to the terminal device address included in the internet of things data initiated by the terminal device may be:
the forwarding node judges whether the total number of terminal devices initiating the data of the internet of things at the same time within the wireless coverage range of the forwarding node exceeds the preset number appointed by the forwarding node; the preset number designated by each forwarding node may be different, which is not limited in the embodiment of the present invention;
if the total number does not exceed the preset number designated by the forwarding node, the forwarding node can initiate an instant weather type query request comprising a terminal equipment address contained in the internet of things data initiated by the terminal equipment to a cloud service platform corresponding to the weather information query port through the weather information query port; the forwarding node can receive an instant weather type corresponding to the terminal equipment address returned by the cloud service platform through the weather information query port;
Or if the total number exceeds the preset number designated by the forwarding node, the forwarding node can determine whether a target node exists around the forwarding node, wherein the total number of terminal devices which initiate the data of the internet of things in the wireless coverage area of the target node is minimum and does not exceed the preset number designated by the target node; if the target node exists, the forwarding node can initiate an instant weather type query request comprising a terminal equipment address contained in the internet of things data initiated by the terminal equipment to the target node, so that the target node initiates the instant weather type query request to a cloud service platform corresponding to the weather information query port, and the cloud service platform returns the instant weather type corresponding to the terminal equipment address to the target node through the weather information query port; and the forwarding node receives the instant weather type corresponding to the terminal equipment address sent by the target node.
As an optional implementation manner, when the forwarding node determines that the target node exists around the forwarding node, the forwarding node may determine whether the distance between the forwarding node and the target node is smaller than a preset threshold, if so, the forwarding node initiates an instant weather type query request including a terminal device address included in the internet of things data initiated by the terminal device to the target node, so that the forwarding node can query an instant weather type of the terminal device address included in the internet of things data initiated by the terminal device as soon as possible.
As an optional implementation manner, after the forwarding node determines that the total number of terminal devices initiating the data of the internet of things at the same time within the wireless coverage area of the forwarding node exceeds the preset number specified by the forwarding node, and before the forwarding node initiates an instant weather type query request including a terminal device address included in the data of the internet of things initiated by the terminal device to a cloud service platform corresponding to the weather information query port through the weather information query port, the forwarding node may further perform the following steps:
the forwarding node identifies and detects whether the forwarding node is configured with a time period allowing access to the cloud service platform, and if the forwarding node is configured with the time period allowing access to the cloud service platform, the forwarding node judges whether the current system time of the forwarding node is within the time period;
if the current system time of the forwarding node is within the time period, the forwarding node can detect whether the cloud service platform is configured with an identification set of the signed terminal equipment or not; if the cloud service platform is configured with the identification set of the signed terminal equipment, inquiring whether the identification set of the signed terminal equipment comprises the terminal equipment identification of the terminal equipment to which the terminal equipment address contained in the internet of things data initiated by the terminal equipment belongs, and if so, initiating an instant weather type inquiry request comprising the terminal equipment address contained in the internet of things data initiated by the terminal equipment to the cloud service platform corresponding to the weather information inquiry port through the weather information inquiry port.
The implementation of the embodiment can avoid that the forwarding node frequently inquires the instant weather type of the terminal equipment address, so that the power consumption caused when the forwarding node inquires the instant weather type of the terminal equipment address can be reduced.
The implementation of the steps can acquire the instant weather type of the terminal equipment address of the signed terminal equipment, so that the instant weather type of the terminal equipment address of the unsigned terminal equipment can be prevented from being leaked.
In the embodiment of the invention, the forwarding node can encapsulate the data of the internet of things initiated by the terminal equipment into the data elements and report the data elements to the filtering gateway, and the filtering gateway determines the data elements containing the terminal equipment addresses matched with the position information only interested by the aggregation unit from the data elements reported by the forwarding nodes and reports the data elements to the aggregation 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 filtering gateway, so that related reports such as early warning, abnormality and the like can be provided for people.
In the control method of the data reporting frequency of the internet of things of the terminal device described in fig. 3, the forwarding node receives forwarding node indication information including weather types interested by the aggregation unit and terminal device types issued by the aggregation unit through the filtering gateway; and the forwarding node monitors massive Internet of things data initiated by terminal equipment in a wireless coverage range, when the terminal equipment type contained in the Internet of things data initiated by a certain terminal equipment is identified to be consistent with the interesting terminal equipment type, the instant weather type corresponding to the terminal equipment address contained in the Internet of things data initiated by the terminal equipment is queried through the weather information query port, when the instant weather type is identified to be consistent with the interesting terminal equipment type, a data reporting frequency down regulation instruction is sent to the terminal equipment, and the terminal equipment down regulates the Internet of things data reporting frequency. Therefore, the control method described in fig. 3 can flexibly adjust the data reporting frequency of the terminal device that is not interested in the aggregation unit, so as to reduce the workload of the aggregation unit and reduce the occurrence probability of network congestion.
