摘要

文中介绍了一种用于海洋地震勘探拖缆采集系统的水下供电方法。该方法采用菊花链型电源分发,采用最优效率进行电源转化,并加入了逐级上电技术以方便故障排查。该方法实现简单,并且具有转换效率高,结构紧凑等优点。试验表明,本方法能够满足6000m范围内、1920通道规模的系统供电。本方法在远距离分布式系统以及大型传感器网络等应用中,也有着重要的参考价值。
This paper introduces a kind of power supply method for marine seismic streamer acquisition system under the water.This method adopts the daisy chain type power distribution and converts the power with the optimal efficiency,moreover use the step by step technology for facilitate troubleshooting.The method is very simple and of high conversion efficiency and compact structure etc.Experiments show that this method can meet the requirement of power supply system with the range of 6000m and 1920 channels.The method also has the important reference value in the long distance distributed systems and large sensor network applications.
