Example one

On the basis of the networking architecture of the internet of things described in fig. 1, the embodiment of the invention discloses a method for controlling the data reporting frequency of the internet of things of a terminal device. Referring to fig. 2, fig. 2 is a schematic flowchart of a method for controlling a data reporting frequency of an 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. and the filtering gateway receives forwarding node indication information sent by the aggregation unit, wherein the forwarding node indication information comprises the weather type and the terminal equipment type which are interested by the aggregation unit.

In the embodiment of the invention, the weather types in which the convergence unit is interested can include various weather types such as rainy days, sunny days, haze days, typhoon days and the like; the type of the terminal device interested by the convergence unit is used for representing the type and model of the terminal device interested by the convergence unit, wherein the type of the terminal device may include various terminal devices such as a rain gauge, a hygrometer and an irrigation valve.

202. And the filtering gateway transmits the indication information of the forwarding node to the forwarding node.

In the embodiment of the invention, the filtering gateway can send the forwarding node indication information to each forwarding node step by step.

203. The forwarding node stores the forwarding node indication information issued by the filtering gateway.

204. The forwarding node detects massive Internet of things data initiated by the terminal equipment within the wireless coverage range of the forwarding node, wherein the Internet of things data comprises the type of the terminal equipment, the address of the terminal equipment and data content.

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 also 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 data load reported by the terminal device, for example, the data content of the internet of things reported by the humidity sensing terminal device deployed in the farm includes that the data content can be soil volume water content; 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 data content of the internet of things reported by the rain gauge may be rainfall.

205. And the forwarding node identifies whether the terminal equipment type contained in the data of the internet of things initiated by the terminal equipment conforms to the terminal equipment type interested by the convergence unit or not aiming at each terminal equipment, and if so, inquires the instant weather type corresponding to the terminal equipment address contained in the data of the internet of things 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 not consistent with the type of the terminal equipment interested by the aggregation unit, the data packet of the internet of things initiated by the terminal equipment can be filtered. For example, when the forwarding node recognizes that the type of the terminal device included in the internet of things data initiated by the terminal device is a rain gauge and the type of the terminal device interested by the sink unit is a hygrometer, the forwarding node may recognize that the type of the terminal device included in the internet of things data initiated by the terminal device is not consistent with the type of the terminal device interested by the sink unit, and the forwarding node may filter out the internet of things data packet initiated by the terminal device.

As another optional implementation manner, in step 205, when the forwarding node recognizes that the type of the terminal device included in the data of the internet of things initiated by the terminal device is not consistent with the type of the terminal device interested by the aggregation unit, the forwarding node may directly execute step 206.

206. And the forwarding node identifies whether the instant weather type corresponding to the terminal equipment address is consistent with the terminal equipment type interested by the convergence unit, and if not, sends a data reporting frequency down-regulation instruction to the terminal equipment.

207. And the terminal equipment adjusts the reporting frequency of the data of the Internet of things downwards according to the reporting frequency downward instruction.

In this embodiment of the present invention, the report frequency adjustment instruction may include a specified report frequency that is lower than a current report frequency of the terminal device and is assigned by the forwarding node, so that the terminal device may update the current report frequency to the specified report frequency.

As an optional implementation manner, in step 205, 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 the terminal devices which initiate the data of the internet of things in 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, and the embodiment of the present invention is not limited;

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 device address contained in the internet of things data 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 can receive the 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 a preset number specified by the forwarding node, the forwarding node may determine whether a target node exists around the forwarding node, where the total number of terminal devices initiating data of the internet of things simultaneously within a wireless coverage range of the target node is the minimum and does not exceed the preset number specified by the target node; if the target node exists, the forwarding node can initiate an instant weather type query request comprising a terminal device address contained in the internet of things data initiated by the terminal device to the target node, so that the target node initiates the instant weather type query request to a cloud service platform corresponding to a weather information query port, and the cloud service platform returns an instant weather type corresponding to the terminal device 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 a target node exists around the forwarding node, the forwarding node may determine whether a distance between the forwarding node and the target node is smaller than a preset threshold, and if so, 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 the target node, so that the forwarding node can query an instant weather type including the terminal device address included in the data of the internet of things initiated by the terminal device as soon as possible.

As an optional implementation manner, after the forwarding 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 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 the 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, whether the current system time of the forwarding node is within the time period is judged;

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 identifier set of the signed terminal equipment or not; and if the terminal equipment identification set comprises the terminal equipment identification of the terminal equipment address contained in the Internet of things data initiated by the terminal equipment, initiating an instant weather type query 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 query port through the weather information query port.

By implementing the implementation mode, the forwarding node can be prevented from frequently inquiring 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 method comprises the steps of receiving a contract signing request sent by a terminal device, and acquiring the instant weather type of the terminal device address of the contract signing terminal device by the terminal device, wherein the instant weather type of the terminal device address of the contract signing terminal device can be acquired by implementing the steps, so that the instant weather type of the terminal device address of the non-contract signing terminal device can be prevented from being leaked.

In the embodiment of the invention, the forwarding 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 addresses of the terminal equipment matched with the position information which is only interested by the aggregation unit from the data elements reported by each forwarding node 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 filter gateway, so that relevant reports such as early warning, abnormity and the like can be provided for people.

In the method for controlling the data reporting frequency of the internet of things of the terminal device described in fig. 1, a forwarding node receives forwarding node indication information including a weather type and a terminal device type that a sink unit is interested in, which is issued by the sink unit through a filter gateway; the forwarding node monitors massive Internet of things data initiated by terminal equipment within a wireless coverage range of the forwarding node, when the fact that the type of the terminal equipment contained in the Internet of things data initiated by a certain terminal equipment is consistent with the type of the interested terminal equipment is identified, an instant weather type corresponding to the address of the terminal equipment contained in the Internet of things data initiated by the terminal equipment is inquired through a weather information inquiry port, when the fact that the instant weather type is consistent with the type of the interested terminal equipment is identified, 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 of the terminal equipment. It can be seen that the control method described in fig. 1 can flexibly adjust the data reporting frequency of the terminal device that is not interested by the aggregation unit, thereby reducing the workload of the aggregation unit and reducing the occurrence probability of network congestion.

Example two

On the basis of the networking architecture of the internet of things described in fig. 1, an embodiment of the present invention discloses another method for controlling the data reporting frequency of the internet of things of a terminal device. Referring to fig. 3, fig. 3 is a schematic flow chart of another method for controlling data reporting frequency of the internet of things of the terminal device according to the embodiment of the present invention. As shown in fig. 3, the method for controlling the data reporting frequency of the internet of things of the terminal device may include the following steps:

301. and the filtering gateway receives forwarding node indication information sent by the aggregation unit, wherein the forwarding node indication information comprises the weather type and the terminal equipment type which are interested by the aggregation unit.

For example, the forwarding node indication information sent by the aggregation unit may be as shown in table 1, that is:

table 1 forwarding node indication information

As shown in table 1, when the type of the weather in which the aggregation unit is interested is rainy, the type of the terminal device in which the aggregation unit is interested may be a rain gauge, because the aggregation unit is generally interested in the internet of things data (i.e., rainfall) reported by the rain gauge in rainy days; when the type of the weather in which the aggregation unit is interested is a clear day, the type of the terminal device in which the aggregation unit is interested can be a humidity sensing terminal device (such as a hygrometer), and the aggregation unit generally is interested in the internet of things data (namely, the soil volume water content) reported by the humidity sensing terminal device (such as the hygrometer) in the clear day; when the weather type that the convergence unit is interested in is a haze day, the terminal device type that the convergence unit is interested in can be a PM2.5 detector, because the convergence unit is generally interested in the internet of things data (PM2.5 value) reported by the PM2.5 detector in the haze day.

302. And the filtering gateway transmits the indication information of the forwarding node to the forwarding node.

303. The forwarding node detects whether the terminal equipment types of partial terminal equipment exist in the massive terminal equipment in the wireless coverage range of the forwarding node and the terminal equipment types interested by the aggregation unit are matched, and if so, the forwarding node indication information sent by the filtering gateway is stored.

In the embodiment of the invention, if the terminal equipment type of partial terminal equipment does not exist in the massive terminal equipment in the wireless coverage range of the forwarding node is detected to be matched with the terminal equipment type interested by the aggregation unit, the forwarding node can delete the forwarding node indication information sent by the filtering gateway.

304. The forwarding node detects massive Internet of things data initiated by the terminal equipment within the wireless coverage range of the forwarding node, wherein the Internet of things data comprises the type of the terminal equipment, the address of the terminal equipment and data content.

305. And the forwarding node identifies whether the terminal equipment type contained in the data of the internet of things initiated by the terminal equipment conforms to the terminal equipment type interested by the convergence unit or not aiming at each terminal equipment, and if so, inquires the instant weather type corresponding to the terminal equipment address contained in the data of the internet of things initiated by the terminal equipment through the weather information inquiry port.

As another optional implementation manner, in step 305, when the forwarding node recognizes that the type of the terminal device included in the data of the internet of things initiated by the terminal device is not consistent with the type of the terminal device interested by the aggregation unit, the forwarding node may directly perform step 306.

306. And the forwarding node identifies whether the instant weather type corresponding to the terminal equipment address is consistent with the terminal equipment type interested by the convergence unit, and if not, sends a data reporting frequency down-regulation instruction to the terminal equipment.

307. And the terminal equipment adjusts the reporting frequency of the data of the Internet of things downwards according to the reporting frequency downward instruction.

As an optional implementation manner, in step 305, the manner in which the forwarding node queries, through the weather information query port, an instant weather type corresponding to a terminal device address included in the internet of things data initiated by the terminal device may be:

In the method for controlling 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 a weather type and a terminal device type that the aggregation unit is interested in, which is issued by the aggregation unit through the filtering gateway; the forwarding node monitors massive Internet of things data initiated by terminal equipment within a wireless coverage range of the forwarding node, when the fact that the type of the terminal equipment contained in the Internet of things data initiated by a certain terminal equipment is consistent with the type of the interested terminal equipment is identified, an instant weather type corresponding to the address of the terminal equipment contained in the Internet of things data initiated by the terminal equipment is inquired through a weather information inquiry port, when the fact that the instant weather type is consistent with the type of the interested terminal equipment is identified, 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 of the terminal equipment.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a system for controlling data reporting frequency of an internet of things of a terminal device according to an embodiment of the present invention. As shown in fig. 4, the system for controlling the data reporting frequency of the internet of things of the terminal device may include:

a convergence unit 401, a filtering gateway 402, and a forwarding node 403, where:

the filtering gateway 402 is configured to receive the forwarding node indication information sent by the aggregation unit 401, and send the forwarding node indication information to the forwarding node; the forwarding node indication information includes a weather type and an interested terminal device type that are interested by the aggregation unit 401;

the forwarding node 403 is configured to store forwarding node indication information issued by the filtering gateway 402, and detect internet of things data initiated by a large number of terminal devices in a wireless coverage area of the forwarding node 403, where the internet of things data includes a terminal device type, a terminal device address, and data content;

the forwarding node 403 is further configured to identify, for each terminal device, whether a terminal device type included in the internet of things data initiated by the terminal device matches a terminal device type interested by the aggregation unit 401, if so, query, through a weather information query port, an instant weather type corresponding to a terminal device address included in the internet of things data initiated by the terminal device, identify whether an instant weather type corresponding to the terminal device address matches a terminal device type interested by the aggregation unit 401, and if not, send a data reporting frequency down-adjustment instruction to the terminal device, so that the terminal device down-adjusts its internet of things data reporting frequency according to the reporting frequency down-adjustment instruction.

As an optional implementation manner, in the control system of the data reporting frequency of the internet of things of the terminal device shown in fig. 4:

the forwarding node 403 is further configured to execute the above-mentioned sending of the data reporting frequency down-regulation instruction to the terminal device when it is identified that the terminal device type included in the internet of things data initiated by the terminal device is not consistent with the terminal device type interested by the aggregation unit 401.

the forwarding node 403 is further configured to detect, before storing the forwarding node indication information issued by the filtering gateway 402, whether a terminal device type of a part of terminal devices exists in the massive terminal devices in the wireless coverage area of the forwarding node 403 and the terminal device type of interest of the aggregation unit 401 are matched, and if so, execute the forwarding node indication information issued by the filtering gateway 402.

the manner in which the forwarding node 403 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 specifically be:

the forwarding node 403 is configured to determine whether the total number of terminal devices initiating data of the internet of things in the wireless coverage area of the forwarding node 403 exceeds a preset number specified by the forwarding node 403; if the total number does not exceed the preset number specified by the forwarding node 403, initiating an instant weather type query request including a terminal device address contained in the internet of things data initiated by the terminal device to a cloud service platform 404 corresponding to a weather information query port through the weather information query port; receiving an instant weather type corresponding to the terminal device address returned by the cloud service platform 404 through the weather information query port;

or, if the total number exceeds the preset number specified by the forwarding node 403, the forwarding node 403 is further configured to determine whether a target node exists around the forwarding node, where the total number of terminal devices initiating data of the internet of things simultaneously within the wireless coverage area of the target node is the minimum and does not exceed the preset number specified by the target node; if the target node exists, initiating an instant weather type query request comprising a terminal device address contained in the internet of things data initiated by the terminal device to the target node, so that the target node initiates the instant weather type query request to a cloud service platform 404 corresponding to a weather information query port, and the cloud service platform 404 returns an instant weather type corresponding to the terminal device address to the target node through the weather information query port; and the forwarding node 403 receives the instant weather type corresponding to the terminal device address sent by the target node.

the forwarding node 403 is further configured to, after determining that the total number of terminal devices initiating internet of things data while within the wireless coverage area of the forwarding node 403 exceeds a preset number specified by the forwarding node 403, identify and detect whether the forwarding node 403 is configured with a time period allowing access to the cloud service platform 404, and if the forwarding node 403 is configured with the time period allowing access to the cloud service platform 404, determine whether the current system time of the forwarding node 403 is within the time period; if the current system time of the forwarding node 403 is within the time period, detecting whether the cloud service platform 404 is configured with an identifier set of a signed terminal device; if the cloud service platform 404 is configured with the identifier set of the signed terminal device, whether the identifier set of the signed terminal device includes the terminal device identifier of the terminal device to which the address of the terminal device included in the internet of things data initiated by the terminal device belongs is inquired, and if the identifier set of the signed terminal device includes the terminal device identifier of the terminal device to which the address of the terminal device included in the internet of things data initiated by the terminal device belongs, the above-mentioned instant weather type inquiry request including the address of the terminal device included in the internet of things data initiated by the terminal device is executed to the cloud service platform 404.

It can be seen that the control system described in fig. 4 can flexibly adjust the data reporting frequency of the terminal device that is not interested by the aggregation unit, thereby reducing the workload of the aggregation unit and reducing the occurrence probability of network congestion.
