Energy Network System of Contactless Energy transmission Technology for Three Dimensional Underwater Vehicles

电缆作为一种电力供给系统的方式，主要用于水下航行器。该系统具有测量时间长、数据传输实时等优点。但也存在着水下移动时活动范围受限、输出量增大等不便之处。另一种供电方式是采用接插件系统。在此系统中，也存在着许多不方便的地方，如对接时需要稳定，对连接器的绝缘要求也很高。除了该系统之外，还有一种系统是仅靠电池运行车辆，不需要供电，这样的测量时间比电缆和连接器系统短。为了解决这一问题，我们提出了利用电磁感应的非接触式电站系统。当车辆的电池电量减少时，车辆会接近放置在海上的充电站。飞行器和空间站上的线圈是对接的。对接后初级线圈（站侧）被激励，电力通过电磁感应传输。充电完成后，车辆再次返回查询。这样循环往复，直到调查结束。通过这种系统，车辆的活动范围不受限制，线圈从不接触海水，因此永远不会生锈。通过该系统，可以完成以下任务。例如，该车辆通过感应连接器将电力输送到海底观测站。飞行器接收观测数据。之后，车辆停靠充电站，然后将数据发送到母船。CLPS系统有很多用途。

As a method of electric power feeding system, electrical cable is mainly used for the underwater vehicles. This system has some convenient point, such as long time survey and real-time data transfer. However, there are inconvenient point, such as restriction of range of activity and the increase output of vehicle to move around underwater. Another method of electric power feeding system, connector system is used. In this system, there many inconvenient points, such as the necessity of stability while the machine is docking and the necessity of high insulating reservation to the connector, too. In addition to this system, there is the system to run the vehicle only battery without electric power feeding, then the time in survey is shorter than that of the cable and connector system.In order to solve this problem, we are proposing Contactless Power Station (CLPS) system utilizing electromagnetic induction. When the vehicle's battery decreases, the vehicle approaches the charging station which is put in the sea. And the coils on the vehicle and the station are docked. After docking the primary coil (the station side) is excited, and the electric power is transmitted with electromagnetic induction. After the charging, the vehicle returns to the inquiry again. This cycle is repeated until the inquiry ends. By this system the range of vehicle's activity is not limited, and the coils never touch the sea water so never rust. By this system it is possible to do the following mission. For example the vehicle delivers the electric power to the observation station on the seabed with inductive connector. And the vehicle receives the observation data. After that the vehicle docks the charging station then the data is sent to the mother vessel. There are many usages utilizing CLPS system.
