Flight control method and device of unmanned aerial vehicle and unmanned aerial vehicle

Abstract

The invention discloses a flight control method and device of an unmanned aerial vehicle and the unmanned aerial vehicle, the method is suitable for the unmanned aerial vehicle carrying a heating device, and the method comprises the following steps: obtaining a temperature change value of a battery of the unmanned aerial vehicle within a preset time interval; when the change trend of the temperature change value is decreasing, starting the heating device to heat the environment where the battery of the unmanned aerial vehicle is located, and detecting the battery capacity value of the unmanned aerial vehicle; comparing the battery capacity value with a preset capacity value to generate a comparison result; adjusting the flight state of the unmanned aerial vehicle according to the comparison result. The battery temperature of the unmanned aerial vehicle can be detected in real time, and heating is performed when the battery temperature drops, so that the battery temperature is increased, the capacity of the battery is prevented from being reduced, and the use efficiency of the battery is improved; meanwhile, the battery capacity value is detected in real time in the heating process, and the flight state of the unmanned aerial vehicle is adjusted according to the battery capacity value, so that the flight requirement of a user is met.

Description

technical field [0001] The invention relates to the technical field of control of unmanned aerial vehicles, in particular to a flight control method and device of an unmanned aerial vehicle and the unmanned aerial vehicle. Background technique [0002] As the demand for electricity continues to increase, how to stably transmit electricity is an important link. In order to ensure the stability of power transmission, it is necessary to detect the real-time status of each base station and circuit at all times. [0003] The traditional inspection method is manual inspection, but manual inspection is labor-intensive and inefficient, and it is difficult to meet the existing inspection needs. In order to meet the existing detection requirements, the currently commonly used detection method is drone inspection. The detection efficiency of drones is high, the cost is low, and the operation is convenient, which can also greatly reduce the detection intensity. [0004] However, the c...

Problems solved by technology

[0004] However, the current inspection method using unmanned aerial vehicles has the following technical problems: since the commonly used unmanned aerial vehicles are equipped with lithium batteries, when performing inspections in winter or in the cold regions of Northwest China or at high altitudes, due to the low temperature, the unmanned aerial vehicles The chemical reaction speed of the power supply slows down, the resistance of the electrolyte increases, the lithium ion crossing performance deteriorates, the activity decreases, and the discharge current becomes smaller, resulting in a decrease in the available capacity of the battery, poor endurance of the drone, and shortened battery life. The flight distance of the man-machine also reduces the inspection scope and prolongs the inspection time
