A method for estimating the remaining mileage of electric UAV

Abstract

The invention discloses an electric UAV remaining mileage estimation method comprising a step S1 of reading out current battery test data including the electric quantity, voltage and current of a battery through a battery control chip; a step S2 of obtaining electric quantity consumption laws parameters through the battery test data; a step S3 of obtaining laws and parameters between flight states including the flight speed and distance and electric quantity consumption through actual flight data; and a step S4 of calculating a remaining mileage estimated value. The invention can calculate the remaining flight mileage in real time according to the electric quantity of the battery; thus, can reduce human judgment and reduce difficulty in using UAVs; and can automatically calculate the flight distance through an algorithm, and can perform UAV flight operation without multi-user collaboration.

Description

technical field [0001] The invention relates to the field of electricity and mileage calculation of an electric unmanned aerial vehicle, in particular to a device for remaining mileage based on remaining electricity and flight status. Background technique [0002] In order to better operate electric drones and ensure their flight safety, it is very important to know the remaining battery power. At present, the estimation of the remaining power of electric drones is basically based on the voltage of the battery and judgment based on experience. However, there is no better way to give the remaining flight time, and it relies more on personal experience. [0003] At present, the method of judging whether the aircraft can continue to fly by observing the level of battery power not only requires high experience of the operator, but also requires the cooperation of multiple people during the flight, because the power changes in real time. Constantly monitoring the voltage level i...

Problems solved by technology

[0003] At present, the method of judging whether the aircraft can continue to fly by observing the level of battery power not only requires high experience of the operator, but also requires the cooperation of multiple people during the flight, because the power changes in real time. Continuously monitor the voltage level, it is easy to have operational problems, resulting in a plane crash

[0004] In addition, for how far the aircraft can fly, the time and distance given by experience judgments have large errors, especially in some special cases, such as when the temperature is very low, the voltage drops very fast, and previous experience may not be applicable
