Embodiment 1

[0050] Embodiment 1. An electric drone.

[0051] As mentioned in the above background technology, once the power shortage occurs during the flight of the electric drone, it will be very dangerous and may directly lead to a crash. Therefore, it is very important to accurately judge the battery life, but the existing battery life judgment method is too simple, and only gives warning information based on the analysis of battery remaining capacity, flight distance or instantaneous power. However, in the actual flight process, the energy consumption of electric drones is not static. It is neither objective nor intuitive to judge only by flight distance or instantaneous power.

[0052] figure 1 It is a schematic structural diagram of an electric drone according to Embodiment 1 of the present invention, and this embodiment of the present invention will combine figure 1 Be specific.

Abstract

The invention discloses an electric unmanned plane and a cruising ability estimating method thereof, and belongs to the field of unmanned plane. The electric unmanned machine comprises a memory, which is used to store the total electric quantity of a battery and the measured value of the current left electric quantity of the battery; a container, which is used to store the relationship, which is obtained in advance, between the weight of load and the cruising ability; a weight obtaining module, which is used to obtain the actual weight of the load of an electric unmanned plane; and a controller, which is used to estimate the cruising ability of the electric unmanned plane according to the relationship, actual weight of load, total electric quantity of the battery, and current left electric quantity, wherein the cruising ability comprises cruising distance and / or cruising time, and the weight of load should be in the range of carrying capacity of the unmanned plane. On the basis of current technology for estimating the cruising ability of electric unmanned plane, the provided method takes the load of electric unmanned plane into account, and thus the accuracy of estimation for the cruising ability of electric unmanned plane is further improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an electric unmanned aerial vehicle and a method for estimating its battery life. Background technique [0002] With the popularization of small and micro electric drones and their entry into the consumer market, some needs that were previously used by professionals and ignored began to emerge. The electric UAV platform is equipped with a large number of electronic devices, such as autopilot system, steering gear and gimbal, etc. In order to ensure the safe and stable operation of the electric UAV platform, these electronic devices require a stable and effective power supply. The electrical energy of the electric drone platform is provided by various high-energy batteries, including: solar energy, storage batteries and fuel cells. Among them, the battery power supply mode represented by lithium battery is the most widely used one at present. [0003] In the cas...
