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 flight control method of multiple ferry planes driven by an emergency in a delay-tolerant network. The task plane is set to be an unmanned aerial vehicle that collects signals such as images to perform tasks, and the ferry plane is to transmit the messages in the mission plane to the ground. and include the following steps: Step 1: In the process of performing tasks, if the number of messages stored in the task machine exceeds the warning value, then the task machine will set its own state as an emergency state and send an emergency signal to Ground station, the ground station allocates a ferry machine for the mission machine; Step 2: The ferry plane adjusts the flight direction according to the instructions of the ground station, and flies to the mission plane in an emergency state; Step 3: If the ferry The aircraft is not placed in an emergency state. After the high-throughput connection is established between the ferry aircraft and the mission aircraft in the emergency state, if the mission aircraft cancels the emergency state, the ferry aircraft will 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-end...
