背景技术
[0002] 系留无人机作为一种特殊类型的无人飞行器, 和普通无人机一样也具有机内导 航自驾系统等部件, 但又有普通无人机无法比拟的优势, 持续性的供电可以既 保证系留无人机长吋间的飞行之外还可以为系留无人机其他设备提供电源保证 , 完成更多更复杂的载荷要求。

对附图的简要说明
附图说明
[0018] 图 1是本发明系留无人机系统实施例的系统框图。
[0019] 图 2是本发明系留无人机系统实施例中供电单元的电路示意图。 [0020] 以下结合附图及实施例对本发明作进一步说明。
具体实施方式
[0021] 参照图 1和图 2, 系留无人机系统包括系留地面工作站 2和系留无人机 11, 系留 无人机 11通过系留绳与系留地面工作站 2连接, 系留地面工作站包括供电单元和 控制单元, 供电单元用于通过系留绳向系留无人机 11输出大于等于 200V的高压 直流电, 在本实施例中, 供电单元向系留无人机输出 220V的高压直流电。 供电 单元包括电池供电单元 22和市电供电单元 21。
[0022] 电池供电单元 22包括电池 23和三路 DC-DC电路模块 1、 2、 3, 电池 23是采用 24 V直流输出, 三路 DC-DC电路模块呈并联连接在电池 23和系留无人机 11之间, 每 路 DC-DC电路模块包括逆变器、 桥堆和滤波电路, 逆变器的低压输入端与电池 连接, 逆变器的高压输出端与桥堆的输入端连接, 滤波电路包括滤波电容和两 个并联的大功率整流二极管, 滤波电容连接在桥堆的输出端之间, 大功率整流 二极管的负极与桥堆的负极输出端连接, 大功率整流二极管的正极与系留无人 机连接, 桥堆的正极输出端与系留无人机连接。 通过逆变器将电池 24V的直流电 逆变呈 220V的高压电, 在经过桥堆的整流和滤波后, 输出给系留无人机。
[0023] DC-DC电路模块包括报警模块, 报警模块包括继电器 J、 第一指示灯和发声模 块, 在本实施例中发声模块为蜂鸣器, 继电器 J的控制端连接于桥堆的输出端上 , 继电器相当于两个幵关, 每个幵关分别连接在第一指示灯、 蜂鸣器和电池之 间, 当某一个或几个低压转高压的 DC-DC模块发生故障吋, 相连接的继电器断 幵, 常闭触电吸合, 电源正极接通供电至蜂鸣器, 蜂鸣器发出报警声音, 相连 的继电器的另一组常幵触电断幵, 指示灯熄灭, 提示故障点。 大功率整流二极 管的作用是单向导电的特性隔离各电路模块之间的电压压差, 进而隔离各电路 模块互相作用造成内部损耗, 进一步的作用是如果有一路或多路电路模块发生 故障吋不会吸收正常工作的电路模块的能耗, 因为有大功率整流二极管的隔离 , 能正常工作的低压转高压的 DC-DC模块输出的高压直流并不能反向输入到损 坏的低压转高压的 DC-DC模块去, 这样剩余可以正常工作的低压转高压的 DC-D C模块还能够持续供电给系留无人机系统。 [0024] 市电供电单元 21包括整流模块、 两个并联的大功率整流二极管和第二指示灯, 整流模块采用高压整流全桥, 并连接在 220V交流电输入端, 整流模块的输出端 连接有滤波电容, 整流模块的正极输出端与大功率整流二极管的负极和第二指 示灯连接, 大功率整流二极管的正极与系留无人机连接。 当系留无人机使用市 电 220V供电吋, 220V电压接入高压供电线路, 220V交流电压经过高压整流全桥 和滤波电容后变成高压直流电源, 经过可靠性双备份的两个二极管后共同并联 供电给无人机系统, 因为有二极管的隔离作用, 低压转高压的 DC-DC电路模块 所输出的高压直流电压并不会反流到交流转换电路中去。
[0025] 由上可见, 通过多余度的系留无人机低电压或高电压输入, 高压直流的供电, 不仅减小工作电流, 使线路损耗小, 提供了更加可靠的供电线路, 并能提供对 应故障线路的鉴定及报警。
[0026] 工业应用性
[0027] 本案适用于系留无人机领域, 通过本案提高供电电压地供电方式, 减小工作电 流, 使线路损耗小, 继而使得本案的系留地面工作站实现线路损耗小。 并且利 用电池和低压逆变高压传输, 有效减小工作电流, 使线路损耗小, 同吋还具备 指示灯和蜂鸣器发出报警, 另外, 还设置有多路 DC-DC电路模块设置, 提供良 好多余度供电保障性。
