Abstract
Description
Technical Field
[0001] The present application relates to the technical field of recirculating aquaculture, and in particular to a factory-based intelligent aquaculture system, method, equipment, medium and product. Background Art
[0002] Recirculating aquaculture (RCA) is an intensive and efficient farming model, a key area of transformation, upgrading, and green development for my country's aquaculture sector. RCA encompasses production processes such as physical filtration, biochemical reactions, oxygenation and temperature control, and disinfection and sterilization. It requires the integrated use of interdisciplinary technologies, including aquaculture, facility agriculture equipment, and artificial intelligence, to achieve digital characterization and intelligent management of the water quality environment, cultured fish, operational equipment, and energy and power.
[0003] Currently, recirculating aquaculture systems include infrastructure such as aquaculture ponds, vertical flow sedimentation tanks, microfiltration machines, nitrification tanks, and buffer tanks, as well as auxiliary equipment installed on these infrastructures, such as centrifugal pumps, submersible pumps, oxygen generators, and air pumps. Each device is connected by pipes or other devices; valves are also installed on the pipes to control the opening and closing of the pipes. When the aquaculture system is in operation, water is first injected into the aquaculture pond via a submersible pump. The water in the aquaculture pond then passes through the vertical flow sedimentation tanks, microfiltration machines, nitrification tanks, and buffer tanks in sequence before returning to the aquaculture pond, achieving the recycling of aquaculture water. If a device in the aquaculture system malfunctions, causing the aquaculture system to stop operating normally, staff will shut down the equipment and perform maintenance.

[0042] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0043] Glossary:

[0045] A Data Transfer Unit (DTU) is a device used for remote data transmission and is widely used in the Internet of Things (IoT), industrial automation, and remote monitoring. DTUs transmit data from field devices to a central control system or cloud platform via wireless or wired means.
[0046] A Network Video Recorder (NVR) is a device used in video surveillance systems to receive, store, and manage video data from network cameras. Unlike traditional digital video recorders (DVRs), NVRs specialize in processing digital video streams transmitted over the network.
[0047] The embodiment of the present application provides a factory-based intelligent aquaculture system, such as Figure 1 As shown, combined with Figure 3 The system includes: recirculating aquaculture infrastructure, programmable logic controller PLC26, data transmission unit DTU27, network video recorder 28, and server 29.
[0048] The circulating aquaculture infrastructure includes: a culture pond 1, a vertical flow sedimentation device 2, a microfiltration machine 3, an ultraviolet sterilization lamp 4, a nitrification tank 5, an air source heat pump 6 and a buffer tank 7 connected in sequence according to the flow direction of the aquaculture circulating water, and forming a closed loop;
[0049] Each of the infrastructures is connected by a pipeline, and an electric valve 9 is installed at a predetermined position of each pipeline;
[0050] A centrifugal pump 10 is arranged between the ultraviolet germicidal lamp 4 and the nitrification tank 5;
[0051] An air pump 19 connected to the nitrification tank 5 is installed outside the nitrification tank 5; an oxygen generator 25 connected to the buffer tank 7 is installed outside the buffer tank 7;
[0052] A water quality sensor group 16 and an underwater camera 15 are installed in the aquaculture water of the aquaculture pond 1, and an above-water camera 14 is installed above the surface of the aquaculture water;
[0053] An environmental sensor group 12 is installed in the air of the area where the breeding pond 1 is located;
[0054] The microfiltration machine 3, ultraviolet germicidal lamp 4, air source heat pump 6, centrifugal pump 10, air pump 19 and oxygen generator 25 are equipped with a group of working condition sensors 24;
[0055] The water quality sensor group 16, the environmental sensor group 12, the working condition sensor group 24, the microfiltration machine 3, the ultraviolet sterilization lamp 4, the air source heat pump 6, the centrifugal pump 10, the air pump 19, the oxygen generator 25 and the electric valve 9 are connected to the PLC signal connection, the PLC is connected to the DTU signal connection, and the DTU is connected to the server 29 signal connection;
[0056] The above-water camera 14 and the underwater camera 15 are connected to the network video recorder 28 by signal, and the network video recorder 28 is connected to the server 29 by signal.
[0057] Among them, the formation of a closed loop can be understood as: the breeding pond 1, the vertical flow sedimentation tank 2, the microfiltration machine 3, the ultraviolet sterilization lamp 4, the nitrification tank 5, the air source heat pump 6 and the buffer tank 7 are connected in sequence, and the water outlet of the buffer tank 7 is connected to the water inlet of the breeding pond 1.
[0058] The electric valve 9 is used to control the opening and closing of the pipeline in which it is located. Further, the predetermined locations for installing the electric valve 9 include: the water inlet of the breeding pool 1, the water outlet of the breeding pool 1, the water inlet of the centrifugal pump 10, the water outlet of the nitrification pool 5, etc.
[0059] The aquaculture pond 1 is used to raise aquacultured animals, and the aquacultured animals are placed in the aquaculture pond 1 for aquaculture. Furthermore, the aquaculture pond 1 adopts a split-way sewage discharge technology. A surface discharge port is provided at the center of the upper surface of the aquaculture pond 1, a bottom discharge port 17 is provided at the center of the lower surface, and an overflow port 13 is provided on the side of the aquaculture pond 1. The surface discharge port is used to separate the surface oil film and floating leftover bait, and the bottom discharge port 17 is used to separate feces and particulate matter such as leftover bait that sinks to the bottom. The overflow port 13 is used to control the water level of the aquaculture pond 1 to prevent the water level from being too high and causing water overflow.
[0060] The vertical flow precipitator 2 is used to separate large suspended solids from the aquaculture tailwater. The aquaculture tailwater enters the vertical flow precipitator 2 from top to bottom, slowly rises along the vertical flow precipitator 2, and after the suspended solids settle, they are discharged through the sewage outlet at the bottom of the vertical flow precipitator 2. The filtered water overflows from the upper outlet.
[0061] Microfilter 3 is used to separate tiny suspended solids from aquaculture tailwater, achieving solid-liquid separation. Microfilter 3 can intercept suspended solids in the water. Furthermore, microfilter 3 is equipped with an external high-pressure flushing pump, which regularly backwashes the screen and discharges wastewater through the drain outlet.
[0062] The ultraviolet germicidal lamp 4 is used for physical ultraviolet sterilization of aquaculture tail water, destroying the nucleic acid and protein of microorganisms, thereby making them lose their reproductive function and causing their death. The centrifugal pump 10 is used to pressurize the low-level water body treated by the ultraviolet germicidal lamp 4 to the high-level nitrification tank 5.
[0063] The nitrification tank 5 is used for biological filtration. The biological filtration process can be briefly summarized as follows: nitrifying bacteria are cultivated; the nitrifying bacteria convert ammonia nitrogen and nitrite in the water into nitrate, thereby reducing the ammonia nitrogen and nitrite in the water, thereby reducing the harm of ammonia nitrogen and nitrite to the growth of the aquaculture plants.
[0064] The air pump 19 is used to blow air into the nitrification tank 5 to promote the tumbling of the biological filler and provide sufficient oxygen for the nitrification reaction.
[0065] The air source heat pump 6 is used to heat the aquaculture water flowing through it to control the temperature of the aquaculture water.
[0066] The buffer tank 7 is used to regulate the water quality of the aquaculture water.
[0067] Among them, the oxygen generator 25 is used to provide high-concentration oxygen to the buffer tank 7. After the high-concentration oxygen is evenly mixed with the aquaculture water in the buffer tank 7, the buffer tank 7 then transports the evenly mixed aquaculture water to the aquaculture pond 1. In this way, the water obtained by the aquaculture pond 1 is aquaculture water in which oxygen has been evenly mixed, thereby increasing the aquaculture density.
[0068] The water quality sensor group 16 is used to measure the water quality parameters in the breeding pond 1 and send the measured data to the PLC, which then sends the data to the DTU, which then transmits it to the server 29.
[0069] The environmental sensor group 12 is used to measure the air parameters in the area where the breeding pond 1 is located, and send the measured data to the PLC, which then sends the data to the DTU, which then transmits it to the server 29.
[0070] Among them, the operating condition sensor group 24 is used to measure the operating conditions of the microfiltration machine 3, ultraviolet sterilization lamp 4, air source heat pump 6, centrifugal pump 10, air pump 19, and oxygen generator 25, and send the measurement data to the PLC, which then sends the data to the DTU, and then the DTU transmits it to the server 29.
[0071] Among them, the water camera 14 is used to obtain group characteristics such as spatial distribution, movement trajectory, aggregation, and feeding status of the aquaculture objects.
[0072] The underwater camera 15 is used to obtain individual characteristics of the cultured object, such as body length, body width, body thickness, and fin distribution.
[0073] The image data collected by the above-water camera 14 and the underwater camera 15 are transmitted to the server 29 via the network video recorder 28 .
[0074] Among them, the server 29 is installed with an intelligent decision-making model 22 and an intelligent management and control platform 23. The intelligent decision-making model 22 is used to analyze the decision results and send them to the intelligent management and control platform 23. The intelligent management and control platform 23 is used to manage the operating status of the infrastructure, such as performing management operations on each device included in the recirculating aquaculture system through the interface displayed on the platform.
[0075] The working process of the above-mentioned circulating aquaculture system is as follows:
[0076] The water quality sensor group 16 collects water quality parameters in the breeding pond 1 and sends them to the PLC;
[0077] The environmental sensor group 12 collects the air parameters of the area and sends them to the PLC;
[0078] 24 groups of working condition sensors collect the operating parameters of each device and send them to the PLC;
[0079] The above-water camera 14 collects above-water images of the aquaculture pond 1 and sends them to the network video recorder 28 , and the underwater camera 15 collects underwater images of the aquaculture pond 1 and sends them to the network video recorder 28 ;
[0080] The PLC sends the received water quality parameters, air parameters and operating parameters to the server 29, and the network video recorder 28 sends the received above-water images and underwater images to the server 29;
[0081] The server 29 generates control instructions based on water quality parameters, air parameters, operating parameters, above-water images and underwater images. The control instructions are transmitted to the PLC through the DTU. The control instructions include switching quantities and analog quantities. The PLC controls the start and stop of the microfiltration machine 3, ultraviolet sterilization lamp 4, air source heat pump 6, centrifugal pump 10, air pump 19, and oxygen generator 25 through switching quantities. The PLC controls the opening size of the electric valve 9 and the motor speed of the centrifugal pump 10 through analog quantities, thereby forming a factory-based intelligent aquaculture control system.
[0082] An embodiment of the present application provides the above-mentioned factory-based intelligent aquaculture system, which includes a water quality sensor group 16, an environmental sensor group 12, a working condition sensor group 24, an above-water camera 14, and an underwater camera 15. These devices collect on-site data of the aquaculture system and send the collected data to the PLC. After the PLC receives the data, it sends it to the server 29 via the DTU. The server 29 determines the control decision, such as whether to change the operating status of each infrastructure and how to change it, and sends it to the PLC via the DTU. The PLC controls the operating status of each device, thereby automatically controlling the operating status of each device, thereby improving the aquaculture efficiency of the recirculating aquaculture system.
[0083] In addition, compared with the existing technology, this application also sets up an above-water camera 14 and an underwater camera 15 to collect the biological characteristics of the aquaculture objects in real time, so as to understand the growth status of the aquaculture objects in real time, so as to take corresponding measures when the growth status is poor; further, a water quality sensor group 16, an environmental sensor group 12 and a working condition sensor group 24 are set up to monitor the aquaculture water quality parameters, air environment parameters and equipment operation status in real time. In this application, the parameters of various equipment at the aquaculture system site, water quality, environment, working conditions and other multi-factor data are collected to provide the system with complete aquaculture site data, and an intelligent aquaculture algorithm is constructed based on the coupling interaction relationship between the water quality environment, the air environment and the equipment operation, so that the server 29 can provide a more reasonable control plan, realize the precise regulation of water quality and the intelligent management and control of equipment, and thus improve the aquaculture efficiency of the recirculating aquaculture system.
[0084] In addition, in this application, an electric valve 9 is also provided. The opening size of the electric valve 9 can be controlled by the analog signal of the intelligent decision-making model 22, thereby controlling the opening and closing of the pipelines and the flow size of the breeding system, thereby realizing the intelligent and unmanned breeding of the circulating water breeding system.

[0119] In step 203, the time series data and the image data are sent to a pre-trained intelligent decision model, so that the intelligent decision model performs a comprehensive decision analysis based on the time series data and the image data, outputs a decision result, and returns the decision result to the intelligent management and control platform.
[0120] The decision result is used to control the operating status of each device in the circulating aquaculture system.
[0121] Among them, the equipment whose operating status needs to be controlled includes: electric valve 9, centrifugal pump 10, microfiltration machine 3, air source heat pump 6, submersible pump 18, air pump 19, ultraviolet sterilization lamp 4 and oxygen generator 25.
[0122] Furthermore, the operating status of each device includes start and pause. Furthermore, for the electric valve 9, its operating status also includes the valve opening. By varying the opening size, the amount of water flowing into the corresponding device is limited, achieving precise control to improve the efficiency of recirculating aquaculture. For the centrifugal pump 10, the operating status also includes the motor speed. By precisely controlling the motor speed of the centrifugal pump 10, the precise control of the water volume is improved, thereby improving the efficiency of recirculating aquaculture.
[0123] For example, if the time series data detects that the water quality of the aquaculture water is too poor, the intelligent decision-making model 22 analyzes that all the aquaculture water needs to be replaced, then the decision result is to start the submersible pump 18, and open the electric valve 9 at the drain outlet of the aquaculture pond 1 and the water outlet of the reservoir. If it is detected that the aquaculture water has been replaced, the decision result is to suspend the submersible pump 18 and close the electric valve 9 at the drain outlet of the aquaculture pond 1 and the water outlet of the reservoir.
[0124] The intelligent management and control platform 23 opens the stored time series data and image data to the intelligent decision model 22 through the application programming interface API. The intelligent decision model 22 obtains data from the intelligent management and control platform 23 through the application programming interface API and returns the decision result to the intelligent management and control platform 23.
[0125] Furthermore, the intelligent decision-making model 22 extracts data features based on machine learning or deep learning methods, quantitatively analyzes the coupling interaction mechanism of water quality environment-farmed fish-operating equipment, and returns the intelligent decision-making results to the intelligent management and control platform 23 through the application programming interface API.
[0126] Optionally, the intelligent decision-making model 22 includes a water quality prediction model based on LSTM, an environment prediction model based on RNN, a working condition control model based on fuzzy control, a fish feeding behavior analysis model based on ResNet, and an underwater fish detection model based on YOLOv8.
[0127] Among them, the role of the LSTM-based water quality prediction model is to receive water quality parameters such as dissolved oxygen, temperature, pH, etc. collected by the water quality sensor group 16, and predict their long-term and short-term change trends based on the water quality parameters to ensure timely regulation and stabilization of water quality.
[0128] Furthermore, the LSTM-based water quality prediction model introduces a spatiotemporal attention mechanism to enhance the feature extraction of the spatial and temporal dimensions of water quality parameters, so as to better meet the long-term and short-term prediction needs of water quality parameters.
[0129] The RNN-based environment prediction model is used to receive environmental parameters such as temperature, humidity, and carbon dioxide concentration collected by the environmental sensor group 12, and predict their long-term change trends based on the environmental parameters to ensure environmental stability.
[0130] Among them, the function of the working condition control model based on fuzzy control is to receive working condition parameters such as working current and vibration frequency collected by 24 groups of working condition sensors, and adjust the operating status of the equipment according to the working condition parameters to ensure stable operation of the equipment.
[0131] Among them, the function of the fish feeding behavior analysis model based on ResNet is to receive the fish feeding images collected by the underwater camera 14, analyze the feeding status characteristics of the fish according to the feeding images, and divide the results into four categories: strong feeding, medium feeding, weak feeding, and no feeding.
[0132] Furthermore, the ResNet-based fish feeding behavior analysis model introduces an attention mechanism module to enhance attention to the feeding characteristics of fish schools and improve the analysis accuracy of fish feeding status.
[0133] Among them, the function of the underwater fish detection model based on YOLOv8 is to receive images captured by the underwater camera 15, detect individual fish according to the underwater images, and monitor the growth status of the fish.
[0134] Step 204: Send the decision result to each device.
[0135] The intelligent management and control platform 23 transmits the intelligent decision results to the DTU via the 4G / 5G protocol and the MQTT protocol. The DTU transmits the intelligent decision results to the PLC via the aforementioned serial communication or Ethernet communication. The PLC converts the intelligent decision results into control instructions and issues control instructions to the electric valve 9, centrifugal pump 10, microfiltration machine 3, air source heat pump 6, air pump 19, ultraviolet germicidal lamp 4, and oxygen concentrator 25 in the infrastructure via the RS485 interface and the Modbus protocol. In other words, the equipment in step 204 is the electric valve 9, centrifugal pump 10, microfiltration machine 3, air source heat pump 6, air pump 19, ultraviolet germicidal lamp 4, and oxygen concentrator 25.
[0136] Optionally, the decision result is sent to the mobile terminal 30 so that the mobile terminal 30 can remotely control the operating status of each device in the recirculating aquaculture system.
[0137] The mobile terminal 30 can be a PC 20 or a mobile terminal 21 (smartphone). The intelligent management and control platform 23 is connected to the mobile terminal 30 via a 4G / 5G protocol to achieve remote control of the factory-scale intelligent aquaculture system.
[0138] The present embodiment provides the aforementioned factory-scale intelligent aquaculture method, which includes acquiring time series data and image data, and sending the time series data and image data to an intelligent decision model 22. The intelligent decision model 22 outputs a decision result, such as whether to change the operating status of each infrastructure and how to change it, and sends the result to the PLC via the DTU. The PLC then controls the operating status of each device. Therefore, the present application can automatically control the operating status of each device, thereby improving the aquaculture efficiency of the recirculating aquaculture system.
[0139] In addition, the embodiment of the method provides complete aquaculture site data, so that the intelligent management and control platform 23 can provide a more reasonable control solution, thereby improving the aquaculture efficiency of the recirculating aquaculture system.
