Description

Technical Field

[0001] This invention belongs to the field of UAV file deployment, specifically relating to a method and system for large-scale UAV swarm file deployment. Background Technology

[0002] With the development of communication and unmanned technologies, unmanned aerial vehicles (UAVs) are playing an increasingly important role in military, civilian, and commercial fields due to their advantages such as high mobility, strong adaptability, and low cost. However, individual UAVs face various limitations in different missions due to their maximum payload, endurance, and detection radius. Therefore, in some large-scale mission scenarios, large-scale UAV swarms are needed for collaboration among individual UAVs to achieve rapid mission completion. Before UAVs can autonomously execute missions, operators often need to deploy the corresponding mission files to the UAV swarm. Therefore, the rapid and complete deployment of mission files by large-scale UAV swarms has become a crucial issue in UAV swarm applications.

[0003] Traditionally, deploying files for one or a few drones typically involves copying them using storage media or using the scp command to copy files between the drone and the host. Both methods require manual file copying and transfer for each drone. While this is manageable for a small number of drones, the sheer volume of manual file copying is unacceptable for a massive swarm of thousands or even tens of thousands of drones.

[0004] Using other file transfer protocols often fails to guarantee file integrity during deployment, especially in large-scale drone swarm deployments, where the probability of errors increases significantly. Furthermore, unlike unmanned ground systems such as autonomous vehicles, drones are more susceptible to problems with mission files. This can lead not only to mission failures but also, in severe cases, interference and collisions between drones, potentially resulting in crashes.

[0005] Therefore, an efficient and stable method for deploying large-scale drone swarm files is particularly important throughout the mission. Summary of the Invention

[0016] The web server verifies the received deployment file information, and when the verification is successful, the drone terminals are divided into multiple groups according to the drone cluster information and a pre-set number.

[0043] Figure 3 This is a schematic diagram of a large-scale UAV swarm file deployment system provided by the present invention. Detailed Implementation

[0044] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] Example 1:

[0046] This invention provides a method for deploying large-scale unmanned aerial vehicle (UAV) swarm files, such as... Figure 1 As shown, it includes:

[0047] Step 1: The backend server receives the deployment file information and drone cluster information sent by the frontend interface;

[0048] Step 2: The backend server sends the deployment file information and drone cluster information to the drone terminal, and receives packet loss information and / or deployment completion messages from the drone terminal;

[0049] Step 3: The backend server performs packet retransmission based on the packet loss information, generates deployment progress information based on the deployment completion message, and sends the deployment progress information to the frontend interface.

[0050] Specifically, step 1 includes:

[0051] like Figure 2 As shown, the backend server includes an MQTT server and a web server. When selecting a deployment file on the front-end interface, the front-end interface obtains basic file information from the web server via the corresponding API interface of Axios technology, such as the file name, file size, and the URL address where the file is stored on the web server. Simultaneously, the MQTT server sends the drone cluster information received from the drone terminal to the front-end interface, which then obtains the IP address of the drone terminal. The front-end interface displays the obtained deployment file information and drone cluster information and sends these two pieces of information to the MQTT server. In this invention, the front-end interface obtains and displays the deployment file information and drone cluster information, and then sends these two pieces of information to the MQTT server to prepare for deployment.

[0052] Specifically, step 2 includes:

[0053] The MQTT server sends the received deployment file information and drone cluster information to the Web server for verification. The Web server verifies the deployment file based on the URL address of the deployment file, checking whether the deployment file exists, and whether the name and size of the deployment file are consistent with the data sent to the front-end interface. Based on the received drone terminal IP addresses, the drone terminals are divided into multiple groups according to a pre-set number.

[0054] Simultaneously, the MQTT server packages the received deployment file information and drone cluster information into a message packet. This message packet is first sent to one of the drone terminals in one group. The drone terminals in that group parse the message packet, create a blank file with the same filename and size as the received file, and establish an index record array with the number of data packets to be transmitted as its length, initializing the array to 0. Based on the file's URL and filename, the drone terminals in that group actively request the file from the web server. The web server divides the file to be transmitted into 1024KB packets and numbers each packet. The web server then distributes the file packets, each packet carrying the file's content and its index value. The drone terminals receive the data packets, write them to the corresponding positions in the file according to the packet's index value, and simultaneously set the corresponding index value in the index array to 1. This process is repeated until all file packets have been distributed.

[0055] When the drone terminal receives a file packet, it checks if the received content is greater than 0. If it is 0, the file transmission is complete, and the packet loss detection process begins. It iterates through all values ​​in the index array, checking if any are 1. If any value is not 1, it indicates packet loss, and the packet loss index is reported to the MQTT server, initiating the packet loss retransmission phase. If all values ​​are 1, it checks if the actual received file size matches the transmitted size. If they match, the drone has completely received the file. If the file sizes are different, it indicates packet loss, and the packet loss index is reported to the MQTT server, initiating the packet loss retransmission phase. After a drone terminal in a group completes a file transfer, it reports a transfer completion message to the MQTT server. The MQTT server receives and records the number of drone terminals that have completed the file transfer. This invention, by grouping drone clusters, can more effectively and quickly deploy files to large-scale drone clusters, achieving the goal of rapid deployment of task files and system updates for drone clusters. It enables drone clusters to obtain shorter task waiting times. By having the drone cluster actively download files from the web server, it reduces the pressure on the server caused by handling large amounts of information during large-scale deployments and improves the speed of file deployment.

[0056] Specifically, step 3 includes:

[0057] When a drone experiences packet loss, the drone terminal requests packet retransmission from the web server. This process involves two scenarios: First, if the drone terminal knows the number of the lost packet, it directly uploads the packet number to the web server, and the web server resends the corresponding packet to the corresponding drone terminal based on the packet number. Second, if the drone terminal does not know the number of the lost packet, it directly requests the deployment file from the web server, and the web server resends the deployment file to the drone terminal.

[0058] The MQTT server generates deployment progress information based on the number of drone terminals that have received and recorded the completed file transfers. This deployment progress information is then sent to the front-end interface. Once all drone terminals in a group have received the deployment file, the deployment file information packet is sent to the next group. This process continues until all drone terminals have received the deployment file information packet and deployed the file to all drone terminals in all groups, thus completing the file deployment. This invention ensures the integrity of files deployed in a large-scale drone cluster through a packet loss retransmission mechanism and deployment progress information.

[0059] Example 2:

[0063] The file deployment module is used by the backend server to send the deployment file information and drone cluster information to the drone terminal, and to receive packet loss information and / or deployment completion messages from the drone terminal.

[0064] The deployment information feedback module is used by the backend server to perform packet retransmission operation based on the packet loss information, generate deployment progress information based on the deployment completion message, and send the deployment progress information to the frontend interface.
