摘要
针对海底观测网中海洋动力环境参数的长期实时监测问题,研究和设计了深海海洋动力环境原位实时监测系统。该系统采用温盐深仪(电导率、温度、深度(CTD)测量系统)、声学多普勒流速剖面仪(ADCP)、声学多普勒流速仪(ADV)、浊度传感器和溶解氧传感器等海洋仪器作为数据采集设备,搭建了以嵌入式ARM内核微处理器为核心的硬件平台,基于Linux操作系统设计了长期实时监测软件。该深海海洋动力环境原位实时监测系统于2011年4月至10月,在美国蒙特利海湾在接入海底观测试验网——蒙特利加速研究系统(MARS)下连续运行187天,试验结果表明该系统可以长期稳定地实时获取海洋动力环境原位数据。
A system for detection of deep ocean dynamical environments was designed and implemented for long-term re- M-time monitoring of the ocean dynamical environment parameters in sea floor observatory networks. The system uses the marine instruments such as a conductivity, temperature, depth （CTD） detector, an acoustic Doppler current profiler（ADCP） ,an acoustic Doppler velocimeter（ ADV）, a turbidity sensor and a dissolved oxygen sensor as data acquisition devices, and sets up an embedded ARM （the acorn RISC machines）core microprocessor as the hardware platform. Its long term and real time monitoring software was designed based on the Linux operating system. From April to October in 2011, the in situ real-time monitoring system for detection of deep ocean dynamical environments ran for 187 days in the Monterey accelerated research system （MARS）on the Monterey Bay, USA. The experimental results show that the system can stably obtain the in situ data of ocean dynamical environments for a long term.
