摘　　要：为实现可靠的南极冰下湖采样与观测电力和通信保障,研制了南极冰下湖远程控制不间断供电系统。设计控制器冗余和通信冗余的控制方案保证其恶劣环境下长期可靠运行,使用铱星通信系统实现了南极无人环境下远程通信,采用多线程编程技术和安全外壳协议(Secure Shell,SSH)大大提高了通信的实时性和安全性。经野外试验表明,南极冰下湖远程控制不间断供电系统运行稳定,远程数据通信安全可靠,满足南极环境的使用需求。A remote-control-uninterrupted-power-supply system is developed to realize power supply and communication for the sampling and observation of the Antarctic subglacial lakes.Redundancy design of controller and communication ensures the reliable operation of the system in extreme environment for long time.Iridium system is used to realize the remote communication in Antarctic environment.Multi-threaded programming technology and Secure Shell(SSH)protocol is used to improve the real-time and security of the communication greatly.Field test shows that the remote-control-uninterrupted-power-supply system is stable,and the data transmission is safe and reliable,which can meet the requirements of the Antarctic application.
