Description

Technical Field

[0001] This application belongs to the field of UAV data communication technology, and specifically relates to a method for defining a plug-and-play UAV ISR information transmission protocol. Background Technology

[0002] In addition to C2 (command and control) data, the information exchanged between UAVs and ground stations also includes ISR (intelligence, surveillance, and reconnaissance) information. ISR information encompasses data from various sensors, such as radar, electro-optical, forward-looking, and ESM, and comes in diverse formats. Currently, each type of sensor uses its own custom protocol. The receiving party (ground station) needs to be equipped with corresponding decoding software or hardware based on the sensors used by the sending party (UAV). This results in one type of ground station being able to control only one type of UAV (see attached). Figure 1 This approach is costly and cannot achieve system interconnection. To achieve one type of station control for multiple types of machines (with attachments)... Figure 2 If the current design is followed, it would be necessary to cover all payloads, resulting in a very large decoding software or hardware system.

[0003] Therefore, how to design a more effective control system for multiple machine types is a problem that needs to be solved. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a plug-and-play method for defining a UAV ISR information transmission protocol, thereby resolving the problem in the prior art where a single station can only control one type of UAV across multiple types of aircraft.

[0005] The technical solution of this application is: a method for defining a plug-and-play UAV ISR information transmission protocol, comprising:

[0006] Define the auxiliary data of the sensors that need to be used;

[0007] After the drone establishes a wireless link with the ground station, the drone will first transmit the auxiliary data of the sensors that need to be transmitted to the ground for analysis.

[0008] After receiving the auxiliary data from the sensors, the ground station stores it and sends confirmation information to the drone.

[0009] After receiving the confirmation information uploaded by the ground station, the drone begins to send valid sensor detection data;

[0010] After receiving the sensor's detection data, the ground station parses and uses the sensor data according to the description format of the sensor data in the previously received auxiliary data.

[0011] Preferably, the auxiliary data adopts a fixed field + expandable field structure, and is encapsulated in TLV, binary structure or lightweight protocol, including file name, file length, MD5 fingerprint, date, attributes, author and version.

[0012] Preferably, before sending any detection data, the UAV first packages all the sensor auxiliary data that needs to be transmitted for this mission and sends it to the ground station through a dedicated channel or priority frame.

[0013] Preferably, after receiving auxiliary data, the ground station stores the auxiliary data in memory or a local configuration library, binds it with the UAV ID and sensor ID to form a "device-resolution rule" mapping table, and then the ground station generates an ACK packet containing the UAV ID, sensor ID, and auxiliary data reception status, and sends it to the UAV through the uplink.

[0014] Preferably, after receiving the confirmation information uploaded by the ground station, the UAV parses the ACK from the ground station to confirm that the auxiliary data has been correctly received and stored. After confirmation, the UAV starts sensor acquisition, encapsulates real-time detection data according to the protocol, and transmits it to the ground station at the agreed rate and priority.

[0015] Preferably, after receiving the detection data from the sensor, the ground station matches the corresponding sensor and auxiliary data according to the frame header identifier, decodes the data according to the defined format, offset, length, encoding, and coordinates, and stores the decoded data.

[0016] The method for defining a plug-and-play UAV ISR information transmission protocol in this application has the following advantages:

[0017] This ISR information transmission protocol enables "plug-and-play" communication between aircraft and ground stations, allowing one type of station to control multiple types of aircraft, solving the problem of standardization and reducing costs. It also enables system interconnection and improves overall efficiency.

[0018] In particular, this ISR information transmission protocol defines a "file" transmission mode, which can transmit files of any format (such as radar libraries, image templates, etc.), greatly facilitating users' requirements for transmitting uncertain information. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are only some, not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] The first aspect of this application provides a method for defining a plug-and-play ISR information transmission protocol for unmanned aerial vehicles (UAVs), drawing inspiration from the evolution of USB 1.0 to USB 2.0: In USB 1.0, all USB devices required pre-installed drivers on a computer before use. With USB 2.0, driver installation is no longer necessary. Any USB device, when needed, first sends boot information to the computer. The computer can then determine the type of the USB device based on this boot information, enabling effective data exchange and achieving plug-and-play functionality.

[0025] This application adopts an "auxiliary data + sensor data" approach, defining standardized and normalized auxiliary data, which can be defined for sensor data of any format. During information transmission, the auxiliary data (bootstrapping information) is transmitted first, followed by the sensor data. The receiver can then parse the sensor data based on the auxiliary data (see appendix). Figure 4 ).like Figure 3 The specific plan is as follows:

[0026] Step S100: Define auxiliary data (bootstrapping information) for each type of sensor that needs to be used.

[0027] The auxiliary data adopts a fixed field + expandable field structure, and is encapsulated in TLV, binary structure or lightweight protocol, including file name, file length, MD5 fingerprint, date, attributes, author and version.

[0028] By standardizing complete information including sensor identification, data format, and parsing rules, ground stations can acquire all parsing elements at once without additional configuration, providing a reliable data description foundation for plug-and-play functionality.

[0029] In step S200, after the UAV establishes a wireless link with the ground station, the UAV will first transmit the auxiliary data of the sensors that need to be transmitted to the ground for analysis.

[0030] Before sending any detection data, the UAV first packages all the sensor auxiliary data that needs to be transmitted for this mission and sends it to the ground station through a dedicated channel or priority frame.

[0031] A mechanism is adopted to prioritize the transmission of all auxiliary data before the detection data, ensuring that the ground station has the ability to resolve data before receiving the service data, thus avoiding invalid data transmission, resolution failure, or out-of-order data. The reliability and real-time performance of the auxiliary data are further improved through dedicated channels / priority frame transmission, ensuring the stable startup of the entire ISR link.

[0032] In step S300, the ground station receives the auxiliary data from the sensor, stores it, and sends a confirmation message to the UAV.

[0033] After receiving auxiliary data, the ground station stores the auxiliary data in memory or local configuration library, binds it with UAV ID and sensor ID to form a "device-resolution rule" mapping table, and then the ground station generates an ACK packet containing UAV ID, sensor ID, and auxiliary data reception status, and sends it to the UAV through the uplink.

[0034] The ACK packet confirms the reception status, establishes a reliable handshake synchronization mechanism, and ensures that the UAV only sends detection data after the ground station is ready, thereby improving system robustness and transmission efficiency.

[0035] In step S400, after receiving the confirmation information uploaded by the ground station, the UAV begins to send valid sensor detection data.

[0036] After receiving the confirmation message from the ground station, the drone parses the ACK from the ground station to confirm that the auxiliary data has been correctly received and stored. After confirmation, the drone starts sensor acquisition, encapsulates real-time detection data according to the protocol, and transmits it to the ground station at the agreed rate and priority.

[0037] The detection data is distributed according to the agreed rate and priority to improve the orderliness of ISR service transmission and ensure the stable operation of the system in multi-sensor concurrent scenarios.

[0038] In step S500, after receiving the sensor's detection data, the ground station parses and uses the sensor data according to the description format of the sensor data in the previously received auxiliary data.

[0039] After receiving the sensor's detection data, the ground station matches the corresponding sensor and auxiliary data according to the frame header identifier, decodes the data according to the defined format, offset, length, encoding, and coordinates, and stores the decoded data.

[0040] The ground station automatically matches sensor and auxiliary data according to the frame header identifier, enabling accurate diversion and rapid analysis of multi-source data without manual intervention; it automatically decodes and stores data according to preset formats, offsets, encodings, and coordinates, simplifying the ground station architecture, reducing hardware and software costs, and supporting subsequent data playback, interpretation, and fusion applications, thereby improving the efficiency of ISR information utilization.

[0041] In summary, this application has the following advantages:

[0042] By defining auxiliary data first, sending auxiliary data first, confirming it at the ground station before transmitting the detection data, and automatically parsing the auxiliary data, the ground station can automatically identify and parse ISR data of multiple types of UAVs and sensors without having to pre-install dedicated decoding software or hardware. This truly enables plug-and-play sensors and solves the problem in existing technologies where one type of ground station can only be adapted to one type of UAV / sensor, significantly improving the system's versatility, interconnectivity, and scalability.

[0043] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
