This model can save land and water resources and provide a long-term stable and reliable water quality environment for farmed fish. Through filtration, sterilization and oxygenation, the aquaculture wastewater is treated and returned to the system for recycling. Although the initial construction cost and system operation cost of the system are high, and well-trained professional breeding personnel are required for testing and operation, its operation is stable, and the treated water quality meets the standards, which can provide a good water quality environment for farmed fish.

[0032] Furthermore, the relay ports of the intelligent data acquisition controller 7 connected to each contactor are respectively provided with corresponding indicator lights, and when the port is opened by a remote instruction, the corresponding indicator lights will also light up.

[0033] Example 2 Based on the indoor circulating aquaculture intelligent control system provided in Example 1, this embodiment provides a method for using the indoor circulating aquaculture intelligent control system, which includes the following steps: 1) Connect the indoor circulating aquaculture intelligent control system with the corresponding electrical equipment and sensor equipment of the indoor circulating water system; 2) Based on the intelligent data acquisition controller, relevant data of the indoor circulating water system is collected in real time, and the collected data is uploaded to the Internet of Things platform; 3) The intelligent data acquisition controller 7 regulates the corresponding equipment of the indoor circulating water system according to the control instructions issued by the Internet of Things platform.

[0034] Furthermore, in the above step 2), the data uploaded by the intelligent data acquisition controller 7 to the Internet of Things platform mainly include real-time indoor temperature, real-time indoor humidity, system power consumption, inverter set frequency, real-time inverter operating frequency, real-time inverter output current, real-time inverter output power, system water consumption, real-time pH of circulating water, real-time temperature of circulating water, real-time dissolved oxygen content of circulating water, real-time ammonia nitrogen content of circulating water, real-time conductivity of circulating water, real-time turbidity of circulating water and real-time operating status of electrical equipment.

[0035] Furthermore, in the above step 3), depending on the type of equipment, the IoT platform can carry out four types of regulation through the intelligent data acquisition controller 7: the first type is simple timed start and stop; the second type is real-time start and stop regulation based on the corresponding model constructed according to the parameters; the third type is real-time speed control; and the fourth type is operating status monitoring.

[0036] Specifically, regarding scheduled start and stop, according to the needs of breeding, the Internet of Things platform uses intelligent data acquisition controllers to control fluorescent lamps and exhaust fans to start on and off at time during the day and at time at night, and the microfiltration machine, ultraviolet sterilizer and solenoid valve are regularly turned on and off at fixed times every day or week.

[0037] Regarding real-time start-stop regulation, the IoT platform performs real-time start-stop regulation by constructing various types of data feedback regulation models. When the indoor temperature and humidity are too high, and the water temperature is too high, exceeding the threshold, the model sends instructions to turn on the exhaust fan and greenhouse roller shutter machine, and reduces the indoor temperature and humidity by increasing the indoor ventilation volume and covering the sunshade net; when the ammonia nitrogen level in the circulating water body exceeds the threshold, it means that the sewage purification capacity of the biochemical pool needs to be improved. The model sends instructions to turn on the biological pool blower to allow the biochemical pool to have sufficient dissolved oxygen for sewage purification. When the ammonia nitrogen level is still high, the model sends instructions to turn on the standby biological pool blower to allow the biochemical pool to have more dissolved oxygen and more aeration; when the water body When the turbidity exceeds the threshold, it means that there is a lot of feces accumulated in the circulating water system and the sewage outlet. The model sends instructions to open the solenoid valve to discharge sewage and turn on the microfiltration machine to filter the water until the turbidity of the water returns to the normal range. Due to the discharge of sewage and dirt in the circulating system, the water level of the system drops, and the valve needs to be opened to replenish water to the specified water level. The tap water / groundwater / river water will be counted through the smart water meter and uploaded to the Internet of Things platform through the smart digital controller. Data such as historical water consumption and cumulative water consumption will be used to evaluate the water-saving performance of the system.

[0038] Regarding real-time speed control, the IoT platform has established functional relationships between aquaculture density and dissolved oxygen in water, oxygenation density and dissolved oxygen in water, and water flow rate and dissolved oxygen in water. When the aquaculture density of the circulating water system reaches 100kg / cubic meter or above, the model issues instructions, and the Roots blower and water pump operate at 50HZ all day long. When the aquaculture density is 15-30kg / cubic meter, the model issues instructions, and the Roots blower and water pump operate at 30HZ. At this time, the output power of the Roots blower and water pump is about 20% of the rated power. The speed change greatly reduces the energy consumption of the equipment, but does not affect the aquaculture process. As the aquaculture density gradually increases, the model issues instructions to gradually increase the operating frequency of the equipment, thereby increasing the output power. The model adjusts the operating frequency and operating time of the Roots blower and water pump to always ensure that the dissolved oxygen content of the circulating water is within a reasonable range, so that the energy consumption of the system is minimized.

[0039] Regarding operating status monitoring, the power off alarm monitors the operating status of the load in real time. When the instructions issued by the equipment do not correspond to the returned operating status, the IoT platform will inform the staff of the equipment failure by calling, sending text messages and app alarms so that the staff can repair it in time.

[0040] Example 3 In this embodiment, aquaculture experiments were carried out in an indoor circulating water system using the indoor circulating water aquaculture intelligent control system proposed in the present invention.

[0041] All electrical equipment has been powered on. The communication interface of the intelligent data acquisition controller is connected to the temperature and humidity sensor, smart meter / water meter, water pump inverter, Roots blower inverter, and the communication lines of the temperature, dissolved oxygen, pH, ammonia nitrogen, conductivity and turbidity probes for water quality measurement. All data is uploaded to the IoT platform and can be viewed remotely in real time through the mobile phone app. The display of all background data on the IoT platform is as follows: Figure 2 shown.

[0042] We have carried out a grass carp breeding experiment. The parameters related to the breeding water and important control functions are displayed in real time on the mobile app, which is convenient for technicians to view and operate remotely. Figure 3 shown.

[0043] From the data, we can see that through the feedback adjustment of the model, the pH of the aquaculture water is 7.44, which is within the acceptable range for aquaculture, and the dissolved oxygen content is always kept within the range of 4-8mg / L, which not only ensures the aquaculture effect, but also reduces the operating energy consumption. The ammonia nitrogen in the water is 0.02mg / L, the turbidity is 0 TU, and the water pollution is very low. Through the water meter, we can see that the cumulative water consumption is 105 cubic meters. In addition, on the control interface, we can either use the model for automatic regulation or manually set the operating frequency of the inverter and the start and stop time of related equipment.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
