Abstract

In this paper, the development of a portable, multifunctional water quality monitoring system for aquaculture that is based on IoT technology is presented. The system integrates a main control module, sensor module, Human Machine Interface (HMI) module, Wi-Fi module and power module, and is equipped with system software based on Real Time Operating System (RTOS) for scheduling tasks. The main control module collects crucial water quality information, including water temperature (WT), dissolved oxygen (DO), ammonia nitrogen (NH3-N), and pH, through the sensor module and facilitates data interaction with the HMI module. The proposed aquaculture water quality evaluation model utilizes water quality parameters as input to assign a grade based on the evaluation result. These parameters are transmitted wirelessly to the OneNet cloud platform using Wi-Fi modules, enabling users to remotely monitor the water quality through a visual interface. The system structure has been meticulously designed to accommodate both portable and fixed-point remote monitoring applications. The experimental results demonstrate that the system is accurate, stable, and cost-effective, providing a reliable and efficient solution for intelligent aquaculture in small and medium-sized enterprises.

在本文中，我们介绍了一种基于物联网技术的便携式多功能水产养殖水质监测系统的开发。该系统集成了主控模块、传感器模块、人机交互模块（HMI）、Wi-Fi模块和电源模块，并配备了基于实时操作系统（RTOS）的系统软件来调度任务。主控制模块通过传感器模块收集关键的水质信息，包括水温（WT）、溶解氧（DO）、氨氮（NH3-N）和pH等，并负责与HMI模块进行数据交互。提出的水产养殖水质评价模型利用水质参数作为输入，根据评价结果进行水质分级。这些水质参数通过Wi-Fi模块远程传输到OneNet云平台，使用户可以通过可视化界面远程实时监测水质情况。该系统结构经过特定设计，可以支持便携式使用和定点远程监测使用，实现多功能。实验结果表明，该系统准确率高、稳定性好、成本低，为中小型水产养殖企业的智能水产养殖发展提供了可靠、高效的解决方案。
