[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0040] The embodiment of the present invention provides a network method for communication between the national network information intranet and the drone airport, see Figure 1 ,include:

[0041] S1. Obtain an IO interrupt signal based on the state of the drone airport equipment accessing the network, obtain a unique identifier of the drone airport equipment according to the IO interrupt signal, and identify and match the drone airport object model based on the unique identifier of the drone airport equipment;

[0042] S2, obtaining and parsing the drone airport object model to obtain a plurality of structured data, and classifying the structured data to obtain a plurality of data types;

[0043] S3. Matching a corresponding reporting frequency for each data type based on the configuration file of the data type and the reporting frequency requirement, and encapsulating the structured data into multiple messages according to the reporting frequency;

[0044] S4. Send the multiple messages to a message queue for temporary storage, obtain a sorting sequence based on the priority of the message queue, and distribute the messages to the State Grid intranet according to the order of the sorting sequence.

[0045] In some embodiments, the process of obtaining the unique identifier of the drone airport equipment according to the IO interrupt signal in step S1 includes:

[0046] When the drone airport equipment is connected to the network, its specific access behavior or status change will trigger the data acquisition terminal to generate an IO interrupt signal. The data acquisition terminal automatically discovers and identifies the behavior of the drone airport equipment in accessing the network by detecting the IO interrupt signal, thereby obtaining the drone airport equipment.

[0047] Furthermore, when executing step S1, the drone airport physical model is a modeled representation, specifically including: equipment physical characteristics, communication protocols, data interface definitions, functional descriptions, equipment attributes, event services and security requirements.

[0048] In fact, the drone airport model is used to provide parsed data for the data acquisition terminal, so that the data acquisition terminal processes the parsed data and outputs various structured data required for reporting. The structured data includes: device unique identification, drone flight coordinates and airport coordinates. The device unique identification represents a parameter combination used to uniquely identify the drone airport, including but not limited to the device serial number, model code, firmware version number and network interface type.

[0049] In some embodiments, when executing step S2, the data types specifically include: timely reporting type and non-timely reporting type.

[0050] In some embodiments, when executing step S3, the configuration file includes json, xml, ini, and the reporting frequency requirement is determined according to the flight state of the drone. Different flight states correspond to different reporting frequencies, specifically including:

[0052] When the drone is ready to take off, the drone's unique device identification is reported every time it is powered on at the airport, and the reporting frequency is only once each time. The unique device identification is a non-timely reporting type.
