As shown in fig. 2, the method for controlling data filtering of the internet of things based on the transmission duration may include the following operations:
201. the forwarding node monitors massive Internet of things data reported by massive terminal equipment in a wireless coverage range of the forwarding node, wherein each Internet of things data comprises data content and the reporting time of the Internet of things data.
The reporting of the internet of things data to the forwarding node by the terminal device may include:
the method comprises the steps that a load value of a wireless port between a terminal device and a forwarding node is judged, whether the load value is lower than a specified load threshold value is judged, if the load value is lower than the specified load threshold value, whether the current system time of the terminal device is in a time period which is specified by the forwarding node and allows the internet of things data to be reported is identified by the terminal device, if the current system time is in the time period which is specified by the forwarding node and allows the internet of things data to be reported, whether the data content monitored by the terminal device is in a preset data range is identified by the terminal device, and if the data content monitored by the terminal device is in the preset data range, the internet of things data including the data content in the preset data range is reported to the forwarding node by the terminal device. Therefore, the terminal equipment can report the data of the internet of things in the preset data range within the allowed time period of the forwarding node and under the condition that the load value of the wireless port is small, the reporting pressure can be relieved, and the reliability of the terminal equipment for successfully reporting the data of the internet of things can be improved.
202. And the forwarding node determines the interception time of each piece of Internet of things data and determines the transmission time of each piece of Internet of things data according to the reporting time and the interception time of each piece of Internet of things data.
In the embodiment of the invention, the transmission time length of each piece of internet of things data is equal to the difference value between the interception time of intercepting the internet of things data and the reporting time of the internet of things data.
203. And the forwarding node identifies a plurality of internet of things data of which the transmission duration exceeds a maximum time delay threshold corresponding to the forwarding node in the massive internet of things data.
In the embodiment of the invention, different forwarding nodes correspond to different maximum delay thresholds, the maximum delay thresholds corresponding to the forwarding nodes are determined by the current reporting load of the forwarding nodes, the physical positions of the forwarding nodes, the current time and the like, and the maximum delay thresholds are used for ensuring the maximum time of the aggregation unit for receiving the time-efficient internet of things data reported by the forwarding nodes.
204. And the forwarding node filters the plurality of Internet of things data from the massive Internet of things data to obtain residual networking data.

205. And the forwarding node encapsulates the residual networking data into a first data element and reports the first data element to the aggregation unit.

Therefore, the reliability of successfully reporting the data elements can be improved by the mode of reporting the data elements when the reporting load of the forwarding node is small.
In this optional embodiment, the method for controlling data filtering of the internet of things based on the transmission duration may further include the following operations:
when the report load of the forwarding node is greater than or equal to the preset load threshold value, the forwarding node judges whether the residual networking data comprises the internet of things data which is interested by the aggregation unit, and when the residual networking data comprises the internet of things data which is interested by the aggregation unit, the internet of things data which is interested by the aggregation unit and is included in the residual networking data is packaged into a second data element, and the second data element is reported to the aggregation unit. Therefore, the data of the internet of things interested by the aggregation unit can be reported preferentially when the reporting load of the forwarding node is large, the reporting pressure of the forwarding node can be relieved, and the reliability of successfully reporting the data of the internet of things interested by the aggregation unit can be improved.
Further optionally, after determining that the reported load of the forwarding node is not greater than or equal to the preset load threshold, and before the forwarding node encapsulates the remaining networking data into the first data element, the method for controlling the filtering of the data of the internet of things based on the transmission duration may further include the following operations:
and the forwarding node judges whether the identified data of the plurality of internet of things contains the data of the internet of things reported by the terminal equipment interested in the aggregation unit, and when the identified data of the plurality of internet of things does not contain the data of the internet of things reported by the terminal equipment interested in the aggregation unit, the forwarding node triggers and executes the operation of packaging the residual networking data into the first data element.
When the identified internet of things data contains the internet of things data reported by the terminal equipment interested by the aggregation unit, monitoring the target internet of things data which is reported by the terminal equipment interested by the aggregation unit and has transmission time less than or equal to the maximum time delay threshold value and is monitored by the adjacent forwarding nodes in the wireless coverage range, packaging the target internet of things data and the rest internet of things data into a third data element, and reporting the third data element to the aggregation unit. Therefore, when the internet of things data reported by the terminal equipment interested in the convergence unit has longer transmission time, the forwarding node can monitor the internet of things data reported by the terminal equipment interested in the convergence unit and having shorter transmission time, and the integrity of the internet of things data received by the convergence unit is further ensured.
Optionally, the reporting, by the forwarding node, the data element to the aggregation unit may include:
the forwarding node selects two forwarding paths according to a preset leader routing table, and reports a data element to the aggregation unit through the two forwarding paths, wherein the data element can be a first data element, a second data element or a third data element. Therefore, the reliability of successful reporting of the data elements can be improved.
Further optionally, each piece of internet-of-things data may further include a device type and a geographic location of a terminal device that reports the piece of internet-of-things data, where encapsulating, by the forwarding node, the to-be-reported data into a data element may include:
the forwarding node performs duplicate removal on the internet of things data reported by the terminal devices with the same geographic positions and the same device types in the internet of things data to be reported to obtain the duplicate-removed internet of things data, and encapsulates the duplicate-removed internet of things data into data elements, wherein the data elements to be reported can be the remaining internet of things data, the internet of things data which is interested by the aggregation unit in the remaining internet of things data, the remaining internet of things data and the target internet of things data. Therefore, the reporting load of the forwarding node and the processing load of the aggregation unit can be reduced.
It can be seen that, by implementing the method for controlling the data filtering of the internet of things based on the transmission duration described in fig. 2, the data of the internet of things with a large transmission delay can be filtered out, and the data of the internet of things with a small delay is reported to the aggregation unit, so that the timeliness of the reported data of the internet of things is ensured, and the reporting load of the forwarding node can be reduced.
