A method and device for determining flight time based on a multi-axis rotor UAV

Abstract

The invention discloses an endurance determination method and apparatus based on a multi-shaft rotor unmanned plane. A battery pack state of an aircraft is monitored and a real-time discharging current of the battery pack is collected; a voltage of the battery pack is measured; parameters of the current and the voltage and the like are processed, thereby obtaining an SOC of the battery pack; a wireless data transmission module is used for carrying out real-time data transmission and displaying the data on a ground terminal, thereby monitoring the SOC state of the battery all the time; and switching between parallel batteries is realized, so that the aircraft is in a mode above the electric quantity or voltage safety value level all the time. Endurance of the multi-shaft rotor unmanned plane is calculated based on the collected data and flight time of the aircraft under different parameters is also calculated. The method and apparatus have the following advantages: real-time calculation of flight time can be carried out according to a changing battery capacity and aircraft quality; and the flight time of the aircraft can be prolonged to the greatest extent.

Description

technical field [0001] The invention relates to a flight time calculation method, specifically, a method for determining flight time based on a multi-axis rotor UAV, mainly aimed at multi-rotor UAVs that are more suitable for use in the transportation field. technical background [0002] With the development of science and technology and the increase of military-to-civilian equipment, low-altitude unmanned aerial vehicles have been widely used in various civilian fields, such as geographic surveying and mapping, fire protection, public security, emergency response, marine monitoring, major disasters, etc. In terms of geographic surveying and mapping, drones are used to survey and map geographical and terrain conditions; in terms of emergency response, when major traffic accidents occur on urban roads, rescue vehicles and personnel cannot arrive at the scene of the accident in time, and drones are used to investigate and guide the accident scene , to obtain rescue information...

Problems solved by technology

However, this article involves a patent with a large model size and a symmetrical rotor distance of 35cm. It belongs to small and medium-sized UAVs, and the power consumption is not comparable.

In addition, the UAV designed in this paper is a system capable of aerial photography, and its power consumption not only includes the power consumption of the UAV, but the composition of power consumption is more complex.
