Abstract

The present invention proposes a solar energy fault diagnosis method for an automatic charging station for an unmanned aerial vehicle. The power supply assembly of the charging station includes a combiner box connected to a power generation branch. circuit voltage signal U The current Hall sensor; the current Hall sensor is connected to the data acquisition center to upload the voltage signal of the power generation branch U , the micro control unit of the data acquisition center transforms the voltage signal by the data bit rate conversion method U Revert to the output current value of the power generation branch and the output voltage of the power generation branch; the data center establishes the solar cell array voltage-current data model with the output current value and output voltage of the power generation branch, and calls the extreme learning machine algorithm to analyze the data Analyze the working conditions of the solar battery array for fault diagnosis and evaluation; the invention can judge whether the solar battery array is in a normal state or has a failure by detecting the data of the solar battery array.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a solar fault diagnosis method for an unmanned aerial vehicle automatic charging station. Background technique [0002] At this stage, the main factor limiting the further development of UAVs comes from its endurance. Most drones are powered by batteries, and their battery life is limited. In order to increase their battery life, some drones use the method of increasing the battery, but increasing the weight of the drone does not solve the problem of short battery life. better solution. In the current research, many companies and research institutions have designed UAV service stations, such as "A Remote Service Station for Multi-rotor Aircraft", application number: CN201820592352. The autonomous power supply of the drone improves the battery life of the drone. [0003] The UAV service station is usually placed outdoors, and the solar cell array is used to power...
