A main channel power supply circuit in the system is connected with a power supply state judgment circuit, an auxiliary power supply circuit and a main and auxiliary channel switching circuit, and the main and auxiliary channel switching circuit is connected with an auxiliary channel power supply circuit and the power supply state judgment circuit. The auxiliary power supply circuit is connected with the power supply state judgment circuit and the auxiliary channel power supply circuit. The power supply state judgment circuit is used for judging whether the main channel power supply circuit fails or not according to the output end voltage of the main channel power supply circuit; the main and auxiliary channel switching circuit is used for switching to the auxiliary channel power supply circuit to supply power when a fault is judged to exist; the auxiliary power supply circuit is used for supplying power in the power supply process of switching the main channel power supply circuit to the auxiliary channel power supply circuit, and the problems that a power supply system of an existing unmanned helicopter generally supplies power through a single power supply, unpredictable circuit faults are many, the consequence is serious once the power supply faults occur, and the reliability is low are solved.

    本申请提供了一种交叉双旋翼无人直升机及双电源冗余切换系统,该系统中的主通道供电电路分别与供电状态判断电路、辅助供电电路以及主副通道切换电路相连,主副通道切换电路分别与副通道供电电路和供电状态判断电路相连,辅助供电电路分别与供电状态判断电路和副通道供电电路相连;供电状态判断电路用于根据主通道供电电路的输出端电压判断主通道供电电路是否存在故障;主副通道切换电路用于在判断出存在故障时,切换至副通道供电电路进行供电;辅助供电电路用于在主通道供电电路切换至副通道供电电路供电过程中进行供电,解决了现有无人直升机的电源系统一般都是单电源供电,不可预测电路故障多,一旦电源故障后果严重,导致可靠性低的问题。
