Embodiment 1

Referring to FIG. 2, FIG. 2 is a schematic flowchart of a method for detecting a working state of a terminal device based on a filtering gateway according to an embodiment of the present invention; as shown in FIG. 2, a working state detection of a terminal device based on a filtering gateway Methods can include:

201. The filtering gateway receives the data frame reported by the terminal device forwarded by the forwarding node, where the data frame carries the terminal device type, the terminal device address, and the reporting time point of the reported data frame.

The forwarding node that communicates with the filtering gateway may be an edge forwarding node used for direct communication with the terminal device in the Internet of Things, or may be another forwarding node. If the forwarding node is an edge forwarding node, the forwarding node obtains the data frame reported by the terminal device in the coverage of the wireless network, and then forwards the data frame to the filtering gateway or forwards it to the filtering gateway through other forwarding nodes.

Specifically, the aggregation unit is configured for the terminal device on the location of interest (a certain farm) and/or The terminal device corresponding to the terminal device type (hygrometer, smoke sensor, etc.) that is of interest is configured to set a preset reporting time period. For example, the aggregation unit may set the preset reporting time period for the terminal device on a certain farm, or A certain terminal device (such as a hygrometer) sets the preset reporting time period, or the aggregation unit sets the preset reporting time period for the strain sensor on a certain highway bridge. In the embodiment of the present invention, the location information of interest of the convergence unit and the terminal device type of interest of the convergence unit are referred to as information of interest of the convergence unit. The aggregation unit may send the setting parameter of the preset reporting period to the terminal device, and the terminal device sets the preset reporting period according to the setting parameter, and then the terminal device reports the data frame in the preset reporting period.

If the filtering gateway determines that the reporting time point belongs to the preset reporting time period, the process proceeds to step 203; if the filtering gateway does not belong to the preset reporting time period, the filtering gateway ends the process.

203. The filtering gateway determines a target terminal device that does not report the data frame in the preset reporting time period and matches the information of interest sent by the aggregation unit, where the information of interest includes location information and/or convergence of the aggregation unit. The type of terminal device that the unit is interested in;

The aggregation unit sends the information of interest to the filtering gateway, and the filtering gateway determines, according to the information of interest and the reported data frame, that the data frame is not reported in the preset reporting period, and the interested information is sent by the matching aggregation unit. The target terminal device of the information.

As an optional implementation manner, for the preset reporting time period of the terminal device, the filtering gateway may set a receiving time period that matches the preset reporting time period, and when setting the receiving time period, may consider the Internet of Things. The delay caused by the data congestion, the priority of the transmission and reception of the data frame of the terminal device, and the like, and the receiving time period in which the data frame reported in the preset reporting period is received in a reasonable and substantially capable manner.

The filtering gateway obtains the reporting information and reports the information to the aggregation unit according to the last reported data frame of the target terminal device, where the reporting information includes the target terminal device address, the target terminal device type, and the last reporting time point of the target terminal device;

As an optional implementation manner, the filtering gateway reports the report information to the aggregation unit, where the filtering gateway determines, by the forwarding rule table sent by the aggregation unit, the target terminal device address or the target transmission band matched by the target terminal device type; A communication connection is established with the aggregation unit on the target transmission band, and the report information is reported to the aggregation unit based on the established communication connection.

Further, the filtering gateway establishes a communication connection with the aggregation unit on the target transmission frequency band, and reports the report information to the aggregation unit based on the established communication connection, which includes: filtering the gateway to determine the time-frequency resource corresponding to the target transmission frequency band, and the time-frequency resource The report information is reported to the aggregation unit.

Further, the filtering gateway determines the time-frequency resource corresponding to the target transmission frequency band, and reporting the reporting information to the aggregation unit on the time-frequency resource includes: filtering the gateway to determine the physical resource for reporting the reporting information from the target transmission frequency band by using a frequency hopping manner The frequency domain location of the block; the filtering gateway reports the reporting information to the aggregation unit on the time-frequency resource corresponding to the frequency domain location of the determined physical resource block.

Among them, strain gauge sensors distributed on highway bridges are usually powered by "solar energy". On sunny days, the strain gauge sensor can report the collected data frame normally due to sunlight radiation; in the rainy day, the strain sensor cannot report the data frame due to no sunlight radiation (data frame reporting is interrupted, strain gauge sensor temporarily due to weather conditions When the offline unit is in the offline state, the aggregation unit can report the data frame in the preset reporting period. If the preset time period is sunny, the strain sensor does not report the data frame, and the aggregation unit further analyzes whether the strain sensor is offline due to other faults (hardware failure, etc.) according to the last reporting time point, and accordingly, for maintenance. . It can be seen that the instant weather type is further combined to further accurately analyze the working state of the target terminal device and the cause thereof.

Further, before the aggregation unit invokes the weather information query interface and sends the weather type query request to the corresponding cloud service platform through the weather information query interface, the convergence unit detects whether the weather information query interface is in an active state, if the weather information query interface is activated. The state, the aggregation unit performs the step of calling the weather information query interface, and sending a weather type query request to the corresponding cloud service platform through the weather information query interface.

As an optional implementation manner, before the aggregation unit invokes the weather information query interface, and the weather information query interface sends the weather type query request to the corresponding cloud service platform, the convergence unit detects whether the target terminal device type of the target terminal device is The weather identifier is associated (the association relationship is used to indicate that the work of the target terminal device is affected by the real-time weather). If associated, the aggregation unit executes the calling weather information query interface, and sends the weather to the corresponding cloud service platform through the weather information query interface. Type query request.

In the embodiment of the present invention, the forwarding node sends the data frame reported by the terminal device to the filtering gateway, and after the filtering gateway receives the data frame, it determines whether the reporting time point carried in the data frame belongs to the preset reporting time period, and belongs to the reporting time point at the reporting time point. When the time period is preset, the filtering gateway determines that the data frame is not reported in the preset reporting period and matches the information of interest sent by the aggregation unit (including the location information of interest of the aggregation unit or the terminal device type of interest of the aggregation unit). Target terminal device, filtering gateway according to the target end The data frame that is last reported by the end device obtains the report information including the target terminal device address, the target terminal device type, and the last reporting time point of the target terminal device, and reports the information to the aggregation unit, and the aggregation unit analyzes the target terminal device according to the report information. Working status. It can be seen that the working state of the target terminal device is analyzed according to the time point of the target terminal device reporting the data frame, the target terminal device address, and the target terminal device type, so as to ensure the online number of the terminal device and realize the information aggregation in the Internet of Things.
