| 摘要: |
| 近海海洋环境是最易受污染的区域，实时对海洋信息进行监测对近海养殖业、渔业有重要的作用。传统信息采集方法效率低下、传输距离近、能耗高、数据采集不准确，针对上述问题，设计了一种实时海洋信息采集传输系统，采集终端能够自动采集近海海洋环境的温度、溶解氧、pH值并通过无线网络将信息传给岸基协调器，岸基协调器可通过提出的二次卡尔曼滤波方法对信息进行滤波处理并由4G网络将信息上传至云平台。实验结果表明：系统能够对近海海洋环境进行信息实时采集，采集数据误差小，具有较高的一致性，功耗低，用户可随时随地查看信息。 |

| Abstract: |
| The offshore marine environment is the most easily polluted area. The real-time monitoring of marine information system is important for offshore aquaculture and fisheries. The traditional methods of collecting information on offshore marine environment are inaccurate, inefficient, have slow transmission speed, and require high energy consumption. In the view of these problems, a real-time ocean information acquisition and transmission system is designed. An acquisition terminal automatically collects data on the temperature, dissolved oxygen, and pH values of the offshore marine environment, and transmits the information to the shore-based coordinator using wireless network. The shore-based coordinator filters the information by the proposed secondary Kalman filtering method and uploads the information to the cloud platform using a 4G network. The experimental results show that the system can collect real-time information of offshore marine environment, and the data acquisition error is small. Also, the system has high consistency, but consumes less power than traditional methods. Users can view information anytime and from anywhere. |
