Embodiment Construction

[0021] The present invention will be described in further detail below with reference to the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited to the embodiments.

[0022] see Figure 1-7 , the present invention is based on the multi-UAV sensor network wireless charging method, comprising the following steps:

[0023] S1. Use the auction algorithm to allocate the task of wireless charging for the sensor node by the UAV;

[0024] The auction algorithm belongs to a negotiation agreement algorithm. Its principle is that drones allocate tasks through bidding, and the drone with the highest bid can get the task. One of the advantages of the auction algorithm is that it has a clear rule for calculating the bid price. First, all UAVs are based on their own state (current flight path, remaining cruise time) and sensor node information (coordinate position, remaining energy level). ) Select multiple nodes for bidding, and then exc...

Abstract

The invention relates to a charging technology for a sensor network, and is a wireless charging method for a sensor network based on multiple UAVs. The flight path of the man-machine is planned, so that the UAV can cross fixed obstacles and avoid other UAVs and moving obstacles when performing tasks. node to charge. The wireless charging method of the present invention uses an auction algorithm to allocate the tasks of the UAV, and at the same time considers the task allocation and path planning, and performs joint optimization and solution.

Description

technical field [0001] The invention relates to a charging technology for a sensor network, in particular to a wireless charging method for a sensor network based on multiple UAVs (unmanned aerial vehicles). Background technique [0002] Unmanned aerial vehicles (UAVs) are widely used in modern military, industrial, agricultural and commercial fields, and now there are higher and higher requirements for the ability of UAVs to perform tasks. The study of problems and path planning problems becomes particularly important. In industrial and agricultural applications, because wireless sensor nodes are generally located in places where it is inconvenient to manually replace batteries, and in order to save costs or limit the environment, most wireless sensor nodes will not be equipped with energy collection devices such as solar energy, wind energy or thermal energy. One of the popular applications is the use of drones to charge wireless sensor nodes that are distributed everywhe...
