[0002] With global fishery resources dwindling and demand for high-quality aquatic products growing, aquaculture has become a crucial means of ensuring aquatic product supply. Traditional aquaculture methods rely heavily on natural water bodies such as ponds, lakes, or offshore areas, leading to problems such as water waste, environmental pollution, and low aquaculture efficiency. In recent years, recirculating aquaculture systems have garnered widespread attention for their ability to effectively conserve water resources, reduce pollution, and increase aquaculture density.

[0056] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0057] The present invention provides a circulating water ecological fishery breeding system and a control method. Figure 1 To the attached Figure 6 For detailed description. Figure 1 As shown, the recirculating water ecological fish farming system in this embodiment includes a central control unit, a water quality monitoring module, a circulating water treatment module, an ecological regulation module, an energy management module, an environmental adaptation module, a fish behavior monitoring module, and an emergency response module. Each module is connected to the central control unit via communication lines, enabling real-time data transmission and precise execution of instructions.

[0058] In actual applications, the central control unit serves as the control core of the entire system, responsible for receiving and processing data from each module and generating optimization control instructions to adjust the system's operating status. The water quality monitoring module is used to monitor the water quality parameters of the aquaculture water body in real time. These parameters include dissolved oxygen concentration, pH value, ammonia nitrogen content, nitrite content, temperature, and turbidity. The water quality monitoring module collects the above parameters through a sensor array and transmits the data to the central control unit. For example, in a specific implementation scenario, the water quality monitoring modules are set at different depths in the aquaculture pond to ensure that the overall condition of the water body can be fully reflected. The sensor array adopts a multi-point distributed layout to avoid data deviations caused by local anomalies.

[0059] The circulating water treatment module is mainly used to filter and circulate the aquaculture water. Figure 1 As shown, the system comprises a water inlet, a filtration device, a sterilization device, and a water outlet. The water inlet introduces water from the aquaculture pond into the filtration device, which is composed of multiple layers of filter material, including a coarse filter layer, a fine filter layer, and an activated carbon layer, which are used to remove suspended particles, tiny impurities, and organic pollutants, respectively. The filtered water enters the sterilization device, which uses ultraviolet disinfection technology to effectively kill pathogenic microorganisms in the water. Finally, the purified water is re-injected into the aquaculture pond through the water outlet, completing the water circulation process. The central control unit dynamically adjusts the operating frequency and workload of the circulating water treatment module based on data feedback from the water quality monitoring module to ensure that the water quality is always suitable for aquaculture.

[0060] The ecological regulation module is one of the core components of this system. Figure 2 As shown, the system includes a microbial cultivation device, an oxygen regulator, and a nutrient injection device. The microbial cultivation device houses a bioreactor for cultivating beneficial microorganisms, such as nitrifying and denitrifying bacteria. These microorganisms can decompose ammonia nitrogen and nitrite in the water, reducing the accumulation of harmful substances. The oxygen regulator replenishes dissolved oxygen into the water via an air pump and aeration head. The oxygen supply is dynamically adjusted by the central control unit based on real-time monitoring of dissolved oxygen concentration. The nutrient injection device replenishes essential elements such as nitrogen and phosphorus in response to changes in nutrient concentrations in the water, maintaining the ecological balance of the water. In one specific embodiment, the ecological regulation module operates as follows: First, the central control unit acquires real-time data from the water quality monitoring module and analyzes the concentration of harmful substances and dissolved oxygen levels in the water. Second, based on the analysis results, the central control unit activates the microbial cultivation device or the oxygen regulator, and, if necessary, the nutrient injection device. Finally, the ecological regulation module stores the adjustment information in the central control unit for subsequent optimization and control.

[0061] The energy management module significantly reduces overall energy consumption by optimizing energy distribution during system operation. The energy management module consists of a power monitoring unit, a load distribution unit, and an energy-saving control unit. The power monitoring unit monitors the power consumption of each module in real time and transmits the data to the central control unit. The load distribution unit rationally allocates power resources based on the operating requirements of each module to avoid energy waste. The energy-saving control unit optimizes the system's operating mode through intelligent algorithms, such as reducing the operating frequency of the circulating water treatment module during off-peak hours or reducing the operation of non-essential equipment at night. In a specific implementation scenario, the energy management module can reduce the system's overall energy consumption by approximately 30%, providing strong support for sustainable fishery development.

[0062] The environmental adaptation module is used to detect changes in the external environment and adjust system operating parameters, such as Figure 5 As shown, the system includes meteorological sensors and an environmental parameter adjustment unit. Meteorological sensors are installed around the aquaculture site to monitor environmental factors such as temperature, humidity, wind speed, and rainfall. The environmental parameter adjustment unit adjusts the operating status of each system module based on the meteorological sensor detection results. For example, when the temperature drops sharply, the environmental adaptation module activates the heating device to maintain a stable water temperature. When rainfall increases, the circulating water treatment module strengthens its filtration capacity to prevent pollutants carried by rainwater from entering the aquaculture pond. In this way, the environmental adaptation module can effectively respond to changes in the external environment and improve the system's adaptability and stability.

[0063] The fish behavior monitoring module is used to record the activity status of fish to evaluate the suitability of the breeding environment, such as Figure 5 As shown, it includes a camera, a motion analysis unit and a behavior database. The camera is installed above the breeding pond to capture the swimming trajectory and group distribution of fish. The motion analysis unit analyzes the behavioral characteristics of fish, such as swimming speed, direction change frequency and aggregation degree, through image recognition technology. The behavior database stores historical behavioral data and provides a reference basis for the central control unit. In a specific embodiment, the workflow of the fish behavior monitoring module is as follows: first, the camera records the video of fish activities in real time and transmits the video data to the motion analysis unit; second, the motion analysis unit extracts key behavioral features and compares them with the historical data in the behavior database; finally, the central control unit determines whether the fish are under environmental pressure based on the comparison results and generates corresponding control instructions.

[0064] The emergency response module is used to initiate emergency measures in emergencies, such as Figure 6As shown, it includes an alarm unit, an emergency processing unit and a status feedback unit. The alarm unit uses an audible and visual alarm to alert the operator to abnormal situations. The emergency processing unit automatically takes emergency measures according to the preset program, such as closing the water inlet valve, starting the backup power supply or increasing the oxygen supply. The status feedback unit feeds back the emergency status information to the central control unit in real time for subsequent analysis and improvement. In a specific implementation scenario, when the water quality monitoring module detects a sharp drop in the dissolved oxygen concentration, the emergency response module will immediately start the backup air pump to ensure that there is sufficient oxygen supply in the water body, and at the same time notify the operator through the alarm unit to perform manual intervention.

[0065] The specific implementation steps of the circulating water ecological fishery breeding system control method provided by the present invention are as follows: Figure 3 As shown, it includes the following contents: first, the water quality parameters of the aquaculture water body are monitored in real time through the water quality monitoring module, and the data is transmitted to the central control unit; second, the aquaculture water body is filtered and circulated through the circulating water treatment module, and the treatment results are fed back to the central control unit; third, the microbial community in the water body is dynamically adjusted through the ecological adjustment module, and the adjustment information is stored in the central control unit; then, the central control unit analyzes the received data and generates optimization control instructions; finally, the central control unit executes the optimization control instructions to adjust the operating status of each module of the system. In a specific embodiment, the process of the central control unit generating the optimization control instructions is as follows. Figure 4 As shown, the following steps are included: first, obtaining real-time monitoring data, including water quality parameters and fish activity status; second, obtaining historical operation data and comparing it with real-time monitoring data; finally, identifying the operating parameters that need to be adjusted and generating corresponding control plans.

[0066] In order to further improve the control accuracy, the present invention also proposes a comprehensive control algorithm based on water quality parameters and fish behavior. Assuming that the dissolved oxygen concentration is DO, the ammonia nitrogen content is AN, and the fish activity status score is FS, the calculation formula of the comprehensive control index TCI is: TCI = w1×DO+w2×(1 / AN)+w3×FS, where w1, w2 and w3 are the weight coefficients of dissolved oxygen concentration, ammonia nitrogen content and fish activity status, respectively, with a value range of 0 to 1, and satisfying w1+w2+w3=1. By calculating the TCI value, the suitability of the current breeding environment can be quantified, and optimization control instructions can be generated accordingly. For example, when the TCI value is lower than the set threshold, the central control unit will give priority to adjusting the operating parameters of the oxygen regulation device and the circulating water treatment module to quickly improve the water quality conditions.

[0067] In addition, the present invention also provides a method for formulating a purification strategy based on the type of pollution source. When the water quality monitoring module detects that the water body is not in a state suitable for aquaculture, the central control unit will identify the type of pollution source based on the water quality parameters. For example, if the ammonia nitrogen content increases significantly, the pollution source is judged to be fish excrement; if the turbidity increases significantly, the pollution source is judged to be suspended particulate matter. Based on the type of pollution source, the central control unit formulates corresponding purification strategies, such as increasing the operating time of the microbial culture device or strengthening the filtration capacity of the circulating water treatment module. In this way, water quality problems can be solved in a targeted manner and the control efficiency of the system can be improved.

[0068] In summary, the recirculating water ecological fish farming system and control method provided by this invention, through intelligent management by a central control unit, achieves efficient coordination of functions such as water quality monitoring, water circulation, ecological regulation, energy optimization, and emergency response. This system not only dynamically maintains the ecological balance of water bodies but also significantly reduces overall energy consumption, providing reliable technical support for modern fish farming.
