Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0029] Such as figure 2 As shown, the ignition and restart method of the hybrid electric rotor UAV in this embodiment detects the output voltage value of the power generation system, and controls the ignition and restart of the power generation system when the output voltage value is lower than a preset threshold.

[0030] In this embodiment, it is further preferred that before controlling the generator system to ignite and restart, it also includes: performing an operation of increasing the output power of the power generation system, and after waiting for a first preset time length, detecting the output voltage value of the power generation system again, when the When the above output voltage value is still lower than the preset threshold value, the ignition ...

Abstract

The invention discloses an ignition restart method, system and memory of an oil-electric hybrid rotor UAV. The method includes: detecting the output voltage value of a power generation system, and controlling the power generation System ignition restarts. The system includes a voltage detection module and an ignition restart control module; the voltage detection module is used to detect and obtain the output voltage value of the power generation system; the ignition restart module is used to judge the output voltage value, when the output voltage value is lower than When the preset threshold is reached, the power generation system is controlled to restart ignition. It has the advantages of sensitive response, fast response speed, and good reliability, which can effectively prevent the oil-electric hybrid rotor UAV from being forced to land due to air parking, affect the UAV’s lingering time, and improve the flight reliability of the UAV. .

Description

technical field [0001] The present invention relates to the technical field of rotor UAV control, in particular to a fuel-electric hybrid power rotor UAV ignition restart method, system and memory, especially the mid-air ignition restart of a fuel-electric hybrid power rotor UAV. Background technique [0002] At present, multi-rotor UAVs are widely welcomed because of their simple structure, flexible control, vertical take-off and landing, and easy hovering, hovering, and flying around. However, since most multi-rotor UAVs are driven by pure electricity, limited by battery capacity, power and battery weight, they can only be used as consumer products. In the field of industrial applications, rotor UAVs are required to have the characteristics of large load, long battery life, and high reliability. In order to meet the needs of industrial applications of rotor UAVs, the power system is a key area of ​​research. [0003] In the prior art, the propulsion system of the oil-ele...
