Embodiment 1

[0059] In this embodiment, a method for minimizing the task time of a multi-UAV information collection system is provided, figure 1 is a flow chart of steps according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0060] S1: Establish an information collection system model;

[0061] Such as figure 2 As shown, the information collection system model includes: a collection of sensor nodes, an information collection drone, a relay drone, and an information collection center. The sensor node collection and the information collection center are far apart due to the distance between them. The terrain is complex, and it is impossible to communicate directly; therefore, the information collection UAV is connected and communicated with the sensor node, the relay UAV is connected and communicated with the information collection UAV, and the information collection center is connected and communicated with the relay UAV,...

Abstract

The invention provides a method for minimizing task time of a multi-unmanned aerial vehicle information acquisition system. The method comprises the following steps: S1, establishing an information acquisition system model; S2, determining an original problem of the information acquisition system; S3, dividing the original problem into a plurality of sub-problems; S4, processing non-convex sub-problems in the sub-problems; and S5, solving the sub-problems by using an alternate iteration algorithm. According to the method for minimizing the task time of the multi-unmanned aerial vehicle information acquisition system, the data transmission quantity of the information acquisition system in unit time can be maximized, the working time of the unmanned aerial vehicle is minimized, the data transmission efficiency is improved, and long-distance efficient transmission of sensor data is realized.

Description

technical field [0001] The present invention relates to the technical field of UAV communication, and more specifically, relates to a method for minimizing the task time of a multi-UAV information collection system. Background technique [0002] Due to the advantages of high flexibility, high mobility and on-demand deployment, drones have been used in various fields such as disaster relief, fire detection and product transportation. In addition, in the communication supported by UAVs, UAVs have a high probability of establishing high-quality line-of-sight links with ground nodes, which makes UAV communication receive extensive attention and research in the field of wireless communication. In a wireless sensor network, since the sensor nodes have less energy, the UAV can be used to approach the receiving sensor to reduce the transmission power of the sensor, thereby reducing the energy consumption of the sensor. Utilizing UAVs as sensor data collectors is an effective energy...
