The invention provides an uninterruptible power supply method and system for a mooring multi-rotor unmanned aerial vehicle, and the method comprises the following steps: monitoring the capacitance monitoring values of a plurality of capacitors which are connected in series, and solving the parallel resistance of all losses in a battery system and the electric leakage between two electrodes of each capacitor in the plurality of capacitors; calculating equivalent series resistance in the whole battery system; calculating voltages at two ends of each capacitor in the plurality of capacitors according to the equivalent series resistance; and detecting a difference value between the total voltage and the sum of voltages at two ends of a plurality of capacitors in the plurality of capacitors, and selecting to switch to a standby battery power supply or switch to a ground power supply for power supply according to whether the difference value is greater than an overvoltage and undervoltage threshold value. Whether the difference value between the total voltage of the multiple capacitors in the standby power supply and the voltage of the multiple capacitors exceeds the overvoltage and undervoltage threshold value or not can be monitored in real time, relay actions of the ground power supply and the standby battery power supply are rapidly switched in real time, it is guaranteed that the power supply is uninterrupted, and information loss caused by reset of electronic equipment is prevented.
本发明提供一种系留多旋翼无人机不间断供电方法及系统,方法包括以下步骤:监测串联连接的多个电容的电容监测值,求得电池系统中所有损耗分别和多个电容中每个电容的两个电极之间漏电的并联电阻;计算整个电池系统中的等效串联电阻;根据等效串联电阻计算多个电容中每个电容两端的电压;检测总电压与多个电容中若干个电容两端的电压之和的差值,根据差值是否大于过压欠压阈值,选择切换到备用电池电源供电或切换回地面电源供电。本发明能够实时监测备用电源中的多个电容的总电压与其中的若干个电容的电压的差值是否超过过压欠压阈值,进而快速实时切换地面电源与备用电池电源的继电器动作,保证电源不间断,防止电子设备复位造成的信息丢失。
