Problems solved by technology

However, when the ferry plane flies in a simple loop mode, timely adjustments cannot be made according to the message congestion status and location information of the mission machine nodes in the network, resulting in an excessively long average message delay

Abstract

The invention provides a multi-ferry-machine flight control method for emergency state driving in DTN (Delay-tolerant Networking). Task machines are set to means unmanned aerial vehicles for receivingsignals such as an image and the like and executing tasks, and ferry machines are set to means unmanned aerial vehicles for transferring messages in the task machines to a ground station; and the multi-ferry-machine flight control method comprises the following steps that: S1: in the process that the task machines execute the tasks, if the number of stored messages in the task machines exceeds an early warning value, the task machines set respective states as an emergency state and send emergency signals to the ground station, and the ground station allocates the ferry machines to the task machines; S2: the ferry machines regulate flight directions according to instructions of the ground station to fly to the task machines in the emergency state; and S3: if the ferry machines are not setas the emergency state, after the high throughput connection is established between the ferry machines and the task machines in the emergency state, if the task machines cancel the emergency states,the ferry machines fly to the ground station.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a multi-ferry flight control method driven by an emergency in a delay-tolerant network. Background technique [0002] Multi-UAV cooperation is applied in the fields of industry, agriculture, military, emergency rescue and disaster relief, etc., and multi-UAV communication is one of the most important issues in the design of multi-UAV systems. There are many limitations to realize the network based on infrastructure such as ground relay stations and satellites. Generally, Flying Ad-Hoc Networks (FANET) is used to realize the communication between multiple UAVs. Due to the rapid movement of UAVs, random and frequent interruptions will occur in the UAV Ad Hoc network. Delay-tolerant Networking (DTN) can solve this problem in principle. Because DTN has the characteristics of "store-carry-forward", it is suitable for situations where there is no end-to-e...
