冰-海界面声学监测系统的设计与研发

Design and Development of Ice-Ocean Interface Acoustic Monitoring System

为了探索北冰洋重点海域冰下浅表层水文和声学环境特性,分析海冰的生长和消融过程对其产生的影响,本文设计了适于极地的冰-海界面声学监测系统。监测系统采用模块化设计方案,主要包括控制模块、供电模块、通讯模块和各观测模块等,可实现对冰面气象、海冰物理、浅表层声学特性以及水文剖面参数的连续观测。通过对标体结构优化,可增加系统工作寿命,以期实现冰基及海洋漂浮状态下的持续数据采集;观测数据通过铱星通讯模块传输至国内监测平台,实现数据实时传输和自动化观测。该监测系统于2019年1月进行了为期一周的野外试验,验证了系统的可行性和标体结构的合理性。

A polar ice-ocean interface acoustic monitoring system is designed to explore hydrological and acoustic characteristics of the Arctic Ocean surface and the effects of sea ice growth and melting processes on them is further analyzed.The monitoring system adopts modular design scheme,which is composed of control module,power module,communication module and observation module etc.It can continuously obtain surface meteorology,sea ice,acoustic characteristics,and hydrological profile data.By optimizing the structure of the buoy body,the working life of the monitoring system can be increased to realize normal observations based either sea ice or sea water.The observation data is transmitted to the domestic monitoring platform through the Iridium communication module,realizing real-time data transmission and automatic observation.The monitoring system has been undergoing a week-long test in January 2019 to verify the feasibility of the system and the rationality of the target structure.
