摘要

介绍了一种用于海洋地震勘探系统的水下供电方法。该方法采用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。实际海上试验表明,本同步采集方法能够满足6000m范围内、1920通道规模的系统供电。方章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。
An underwater power supply method for marine seismic survey system is introduced.The method adopts daisy chain power distribution,utilizes optimized efficiency to carry out power conversion,and adds in power-on step by step technology to facilitate trouble shooting.This method features easy to implement,high conversion efficiency,compact structure,etc.The practical see test shows this synchronous acquisition method is able to meet the need of the power supply for a system with 6000m of range and 1920 channels.This method also has important reference value for the applications of remote distribution system and large sensor network.
