Embodiment

[0034] The UAV is roughly divided into three processes from take-off to landing, namely the take-off phase, the cruising phase and the landing phase. Take the UAV engine power level as 4kw as an example, the speed range is between 0rpm and 7500rpm, and the engine is in an idle state in the range of 0rpm to 2500rpm, unstable, which is not conducive to power generation at this time, and the engine is already overloaded in the range of 5500rpm to 7500rpm At this time, it is not suitable to split part of the power for power generation, so the engine power range suitable for power generation is 2500rpm to 5500rpm.

[0035] Such as figure 1 As shown in (a) and (b), the interval power generation module uses a "frequency / voltage" converter LM331 to directly collect the engine speed pulse signal, and convert the pulse frequency into a voltage signal in proportion; after that, use the LM339 double-threshold voltage to compare The device converts the proportionally converted voltage sig...

Abstract

The invention provides a small-sized long-endurance fixed-wing unmanned aerial vehicle power supply controller system and a running method. The small-sized long-endurance fixed-wing unmanned aerial vehicle power supply controller system comprises a rectification voltage stabilizing module, an interval power generating module and a power supply switching module; three-phase alternating current generated by a power generator is converted to direct current required by unmanned aerial vehicle airborne electronic control equipment by utilizing a three-phase rectification bridge, and the voltage isstabilized in a certain range; the interval power generating module comprises a frequency-to-voltage module and a voltage-to-switching value module which jointly control and decide the function that whether an engine generates power or not in different frequency interval sections; and the power supply switching module realizes switching of power supplying sources of the unmanned aerial vehicle airborne equipment. The small-sized long-endurance fixed-wing unmanned aerial vehicle power supply controller system aims to supply power for the airborne electronic control equipment by utilizing the engine to generate power, meanwhile, a complicated single ship computer is not expected to be introduced for controlling, the rotating speed of the engine can be distinguished only through hardware design, power supplying in a suitable interval is achieved, and smooth switching between power supplying by a storage battery set and power supplying by the power generator is achieved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a design system and an operation method for a power controller of a small long-endurance fixed-wing unmanned aerial vehicle. Background technique [0002] With the advancement of UAV technology, small UAVs have been widely used in border patrol, aerial photography, logistics distribution, military investigation and other fields. UAVs with a battery life of more than 24 hours are called long-endurance UAVs. Long-endurance UAVs are generally used to perform strategic or campaign reconnaissance missions, have persistent intelligence collection and battlefield surveillance capabilities, and can be used as unmanned vehicles. Combat platforms have thus become the focus of the development of weapons and equipment in various countries today. [0003] In addition to power, the factors that limit the long-term endurance of UAVs are the power supply of the UAV’...
