摘要
大型船舶在航海过程中会使周围海域压力场发生变化,压力大小与船舶航行速率、吨位大小及气候环境相关,水压场测量技术是舰船动力系统的重要研究领域之一。三元阵列是测量深海领域船舶微弱水压场的主流技术,通过压力传感器采集水压数据,随后进行算法处理,得到的压力值精确度高,且算法实时性较好,得到了较为广泛的应用。本文分析深海船微弱水压测量压力,利用三元阵列技术给出船舶微弱水压场特征值的提取方法,最后进行仿真。
The large ships can change the pressure field around the sea area on the voyage,the pressure is related to the ship' s navigation speed,tonnage and climate environment. Water pressure field measurement technology is one of the important directions of ship manufacturing industry. The three element array is the main technique to measure the weak water pressure field in the deep sea,The pressure data is collected by the pressure sensor,and then the algorithm is processed,the pressure value is high,the algorithm has better real- time performance,it has been widely used. In this paper,the pressure of weak water pressure measurement of deep sea ship is analyzed,and the method of extracting the characteristic value of the ship's weak water pressure is given by using the three element array technique.
