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。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。
An underwater power supply method for marine seismic exploration system is introduced. The method uses a daisy chain power distribution, the use of optimal efficiency for power conversion, and joined the step by step power-up technology to facilitate troubleshooting. The method has the advantages of simple implementation, high conversion efficiency, compact structure and the like. The actual sea trials show that the synchronous acquisition method can meet the system power supply of 6000 channels and 1920 channels in size. The method also has important reference value in applications such as remote distributed system and large-scale sensor network.
