英文摘要	In order to monitoring on the dissolved oxygen (DO) status of different water layers in marine ranching in the real-time, online and continuous, this paper designs a multi-layer marine dissolved oxygen online monitoring system. It integrates an optical dissolved oxygen sensor developed independently and designed the chain-type DO section measurement structure. The data acquisition and control system is designed based on STM32 single-chip. And the wireless transmission module communicating with the remote control center is used to complete the real-time update and visual display of the data, which realize the expression of the remote control command to the monitoring system. The results show that the drift of DO probe can be controlled within 3%, and the whole system displayed the good stability, high reliability. It is convenient for users to check the current dissolved oxygen status of seawater and view historical data. In 2016 to 2018, the system has been applied to the east ocean Yunxi marine ranching in Yantai, Shandong. The observation data shows that DO and temperature show similar laws. The concentration of DO in the surface water is high with small variation range. The variation range of DO in the middle sea water is obviously higher than that in the surface layer and the bottom layer. And the DO in the bottom sea water shows a continuous downward trend without obvious vertical mixing. During the observation period, the bottom sea water of marine ranching appeared hypoxia for more than 18 days in 2016 and 2017, and the time series change trend of the test data is consistent with the weather change, which provide early warning and forecast for the aquaculture enterprises of marine ranching and reduce the economic loss caused by hypoxia disaster.
中文摘要	为满足海洋牧场养殖区域多水层溶解氧(dissolved oxygen,DO)含量实时、在线、连续监测的需求,本文设计了一种剖面DO在线监测系统,系统集成自主研发的光学DO传感器,设计了链式DO剖面测量结构,开发了基于STM32单片机的数据采集与控制系统,通过无线传输模块与远程监控中心通信对接,实现了海洋牧场多水层DO监测数据的实时传输与可视化显示,方便用户查看当前海水DO及温度变化状况、历史数据及变化趋势。性能测试表明,本系统DO探头漂移可控制在3%范围内,整套系统的稳定性好、可靠性高。2016年至2018年,本系统在山东烟台的东方海洋云溪牧场进行了应用示范。观测数据显示:DO与温度表现出相似的变化规律,即表层>中层>底层;表层水DO浓度较高且变化幅度较小,中层海水DO变化幅度明显高于表层和底层,底层海水在未有明显的垂直混合作用下,DO呈持续走低趋势。观测期间,2016年和2017年海洋牧场底层海水均出现了长达18 d以上的低氧现象,且测试数据的时间序列变化趋势与天气变化相吻合,为海洋牧场的养殖企业提供了预警预报,减少了低氧灾害所带来的经济损失。
