海洋牧场鱼类驯化中的声音监测系统设计

摘要

Taming the fish in the oceanic pasture by taking the nature fish sound tends to improve the efficiency. Sound supervising system is designed according to the special requirement in the oceanic pasture opening environment. Hydrophone layout and data collection under the condition of the variable nature fish sound pressure is particularly discussed. Over strength signal area and over distance signal area are defined which provide scientific reference to design a reasonable sound supervising system. By adopting RHS-15 hydrophone, the valid small signal supervising method of variable fish sound pressure amplitude and frequency is obtained.%采用鱼类所发声音进行海洋牧场中鱼类生活规律驯化可望提高驯化效率；根据海洋牧场中相对开放式环境的要求进行了声音监测系统设计,重点考虑了鱼类自然声音声压变化情况下水听器的分布式使用和数据采集方法,定义了过强信号作用区域和最远有效作用区域的概念,为设计科学有效的声音监测系统提供参考；利用RHS-15水听器进行检测,获得了幅值和频率变化情况下小信号水下声压的有效检测方法.
