随着水产养殖业的不断发展，传统的罗非鱼养殖方式面临着水质监测不及时、人工操作繁琐等问题，难以满足高效养殖的需求。为此，本研究设计了一款基于STM32F103C8T6单片机的智能罗非鱼塘养殖系统，旨在通过智能化手段实现对鱼塘水质的实时监测与精准控制，提高养殖效率和鱼的生存环境质量。
该系统以单片机作为主控制器，通过防水式DS18B20传感器检测鱼塘水温，当水温超出预设范围时，触发声光报警；通过pH检测模块监测鱼塘水的pH值，一旦异常，不仅声光报警，还会通过手机端弹窗提醒用户；浑浊度传感器可实时监测鱼塘水体浑浊度，当浑浊度过高时，系统声光报警并提醒投放净水剂；氧气检测模块能够实时检测鱼塘溶氧量，当氧气浓度过低时，触发声光报警并通知手机端。通过按键手动设置阈值并控制增氧机开关，并通过OLED显示屏直观显示各项数据。借助WIFI模块，测量数据可实时传输至手机端，用户可远程设置阈值及控制增氧机，实现智能化管理。
经过实物测试，系统运行稳定，各项传感器数据采集准确，报警功能灵敏可靠，远程控制响应迅速，能够有效满足罗非鱼塘养殖的智能化管理需求，具有良好的应用前景和推广价值。

With the continuous development of aquaculture, traditional tilapia farming methods are facing problems such as untimely water quality monitoring and cumbersome manual operations, which are difficult to meet the needs of efficient farming. Therefore, this study designed an intelligent fish pond aquaculture system based on STM32F103C8T6 microcontroller, aiming to achieve real-time monitoring and precise control of fish pond water quality through intelligent means, improve aquaculture efficiency and the quality of fish living environment.
The system uses a microcontroller as the main controller and detects the water temperature in the fish pond through a waterproof DS18B20 sensor. When the water temperature exceeds the preset range, an audible and visual alarm is triggered; Monitor the pH value of fish pond water through the pH detection module. Once there is an abnormality, not only will it sound and light an alarm, but it will also remind the user through a pop-up window on the mobile phone; The turbidity sensor can monitor the turbidity of fish pond water in real time. When the turbidity is too high, the system will sound and light an alarm and remind to add water purification agent; The oxygen detection module can detect the dissolved oxygen level in the fish pond in real time. When the oxygen concentration is too low, it triggers an audible and visual alarm and notifies the mobile phone. Manually set the threshold and control the aerator switch through buttons, and visually display various data through an OLED display screen. With the help of WIFI module, measurement data can be transmitted in real-time to the mobile phone, and users can remotely set thresholds and control aerators to achieve intelligent management.
After physical testing, the system runs stably, with accurate data collection from various sensors, sensitive and reliable alarm functions, and rapid remote control response. It can effectively meet the intelligent management needs of Luofei fish pond aquaculture and has good application prospects and promotion value.
