海底地震观测的非接触连接器设计及试验

为了将有缆式海底地震仪连接到海底观测网,以便向地震仪提供电能并传输数据,提出一种非接触式水下连接器设计,并对该设计进行功能验证。非接触式连接器利用电磁耦合原理,采用特殊电磁线圈传输电能和信号,通过控制电能和信号传输的频谱分布来避免二者传输时的相互干扰。实验给出连接器的电磁线圈设计以及硬件电路设计,并通过实验测试来验证设计的正确性及可靠性。

Design and test of contactless connector for ocean bottom seismic observation

A contactless underwater connector is designed for connect cable ocean bottom seismograph with undersea observatory network to supply electric power and transmitting information for seismograph. The design technique will be proved by experiments. The connector utilizes the principle of electromagnetic coupling and uses two sets of coils which are wound in special magnetic cores to complete the transmission work. It avoids mutual interference between electric power and signal transmission by controlling their frequency spectrum. The electromagnetic coils and circuit of the connector are designed to verify whether it is accurate and reliable through the experiments.
