[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-6This utility model provides a technical solution: a water quality control device for aquaponics based on intelligent monitoring, including a fish pond 1 and a plant cultivation trough 2, which are connected by a water pipe 3; a water quality monitoring module 4 is installed in the fish pond 1 and the plant cultivation trough 2 to collect water quality parameters; an intelligent analysis module 5 is fixedly installed inside the device housing 50 and electrically connected to the water quality monitoring module 4; an execution control module 6 is electrically connected to the intelligent analysis module 5 and includes an aeration device 61, a water circulation pump 62, an automatic dosing device 63, a temperature control device 64, and a light device 65; a zoned circulation module 7 includes a first circulation pump 71 and a second circulation pump 72 respectively connected to the fish pond 1 and the plant cultivation trough 2, both of which are electrically connected to the intelligent analysis module 5; a human-computer interaction module 8 includes a display screen 81 and a remote control terminal 82, the display screen 81 is installed on the outer wall of the device housing 50 and connected to the intelligent analysis module 5, and the remote control terminal 82 is connected to the intelligent analysis module 5 through a wireless communication module 83. A closed water circulation system is constructed by continuously flowing water between fishpond 1 and plant cultivation trough 2. A water quality monitoring module 4 collects key water parameters in real time, which are then centrally processed and used for decision-making by an intelligent analysis module 5. During operation, the water circulation pump 62 drives water from fishpond 1 to plant cultivation trough 2, and then returns via water pipe 3 to form a circulation. During this circulation, dissolved oxygen, ammonia nitrogen, and turbidity sensors installed on the inner wall of fishpond 1, and pH, temperature, and conductivity sensors installed on the inner wall of plant cultivation trough 2, work synchronously to upload various water quality parameter data to the intelligent analysis module 5 in real time. The intelligent analysis module 5 compares and analyzes the current parameters with the system's set thresholds. When a certain indicator deviates from the preset range, the execution control module 6 is triggered to carry out targeted adjustment operations: If the dissolved oxygen concentration is insufficient, the aeration device 61 is controlled to work, and air is injected into the Venturi injector 611 through the air pump 613, so that it mixes with the water delivered by the circulating water pump 612 in the injector. The mixture is then released as fine bubbles through the gas-liquid mixing chamber 615 and the microporous diffuser head 617, thereby increasing the dissolved oxygen level in the water. If the water temperature is lower than the set value, the heating rod in the temperature control device 64 is activated to heat the water. If the pH value is abnormal, the metering pump 632 in the automatic dosing device 63 injects the medicine solution from the medicine storage tank 631 into the fish pond 1 through the dosing pipe 633 to adjust the water quality. At the same time, the first circulation pump 71 and the second circulation pump 72 of the zoned circulation module 7 can operate independently according to the analysis results, realizing differentiated water quality control between the fish pond 1 and the plant cultivation tank 2. All adjustment status and parameter information are displayed in real time on the display screen 81. Users can also issue control commands through the remote control terminal 82. The commands are transmitted to the intelligent analysis module 5 via the wireless communication module 83 to realize remote monitoring and intervention.Through the coordinated operation of the above modules, the system can achieve dynamic detection, intelligent analysis and rapid regulation of water quality parameters, ensuring a stable and efficient growth environment for fish and plants in the symbiotic environment.

[0018] Preferably, the water quality monitoring module 4 includes a dissolved oxygen sensor, a pH sensor, an ammonia nitrogen sensor, a temperature sensor, a conductivity sensor, and a turbidity sensor. The dissolved oxygen sensor, ammonia nitrogen sensor, and turbidity sensor are fixedly installed on the inner wall of the fishpond 1 and electrically connected to the intelligent analysis module 5 via signal wires. The pH sensor, temperature sensor, and conductivity sensor are fixedly installed on the inner wall of the plant cultivation trough 2 and electrically connected to the intelligent analysis module 5 via signal wires. By deploying sensors with different functions in the fishpond 1 and the plant cultivation trough 2, multi-point real-time monitoring of water quality parameters is achieved. All sensors use a threaded locking structure or a sealed insertion structure, directly fixed to the inner wall of the container, with the probe end exposed in the water to ensure sensing accuracy. The sensor model is selected according to the measurement range and accuracy requirements. For example, the dissolved oxygen sensor uses a fluorescence or polarographic sensor, the pH sensor uses a composite glass electrode structure, the ammonia nitrogen sensor is an ion-selective electrode type, the temperature sensor is a platinum resistance or thermistor type, the conductivity sensor is an electrode type or an inductive structure, and the turbidity sensor is a scattered light detection type. All sensors are connected to the intelligent analysis module 5 via shielded signal wires, using RS485 or analog signal input to ensure interference resistance and stability. The sensor layout is configured according to areas of concentrated fish metabolism and plant root growth, improving monitoring efficiency. Through simultaneous uploading of data from multiple points, the intelligent analysis module 5 can comprehensively assess water conditions in real time, precisely control the operation and intensity of various control devices, and enhance the system's intelligence level and water quality management efficiency.

[0019] Preferably, the aeration device 61 includes a Venturi injector 611 and a circulating water pump 612. The outlet of the circulating water pump 612 is connected to the water inlet of the Venturi injector 611. An air pump 613 is connected to the air inlet of the Venturi injector 611 via a pressure stabilizing tank 614 and a one-way valve 616. The mixing outlet of the Venturi injector 611 is connected to the gas-liquid mixing chamber 615. The circulating water pump 612 acts as a hydrodynamic source, drawing water into the Venturi injector 611 to form a high-speed water flow. The water is then drawn into the air pump 613 through the negative pressure zone of the internal contraction section of the injector. Compressed air is supplied at constant pressure through the pressure stabilizing tank 614 and prevented from flowing back to the air source by the one-way valve 616. After the water and air are mixed, they flow into the gas-liquid mixing chamber 615 for secondary mixing and are finally evenly released into the water through a diffuser, thereby improving oxygen transfer efficiency.

[0020] Preferably, the automatic dosing device 63 includes a drug storage tank 631, a metering pump 632, and a dosing tube 633. The drug storage tank 631 is connected to the metering pump 632 via a flexible hose, and the dosing tube 633 is inserted into the fishpond 1. The drug storage tank 631 is used to store liquid drugs for adjusting pH or nutrients, and is made of acid and alkali resistant polyethylene. It has a sealed cap and a liquid level observation window. The metering pump 632 is an electrically controlled peristaltic pump, whose start / stop and flow rate are controlled by the intelligent analysis module 5 to achieve on-demand dosing. The dosing tube 633 is made of food-grade silicone tubing and is fixed to the wall of the fishpond 1 with a tube clamp to ensure that the drug solution is injected close to the circulation inlet to accelerate mixing. This structure enables precise and controllable adjustment of water quality parameters, especially with rapid response to drastic fluctuations in ammonia nitrogen and pH. The type of drug, dosing frequency, and dosage can be set and recorded in the intelligent analysis module 5, and remote modification is supported.

[0021] Specifically, both the first circulation pump 71 and the second circulation pump 72 are equipped with check valves to prevent backflow when one of the circulation pumps is shut down. The check valves are installed on the outlet pipes of the first circulation pump 71 and the second circulation pump 72, and are spring-return type check valves. The valve body is made of PVC or stainless steel, and the flow direction is clearly indicated by arrows. The check valve structure ensures that when one pump stops operating, water will not flow backwards through the closed passage to the non-working area, avoiding water quality disturbance and energy waste.

[0022] Specifically, the display screen 81 is a touch screen, used to display real-time water quality parameters and perform local operations.

[0023] In this embodiment, the display screen 81 is a 7-inch industrial-grade TFT capacitive touchscreen, covered with a waterproof acrylic sheet and mounted to the outer wall of the device housing 50 via a sealing ring. The screen is connected to the intelligent analysis module 5 via serial communication, displaying all sensor values, device operating status, alarm information, and historical records in real time. The interface supports touch menu switching, parameter setting, and data export. The screen supports multilingual interfaces and adaptive brightness adjustment, offering excellent visibility and interactivity, and is suitable for outdoor or semi-outdoor use.

[0024] Preferably, the remote control terminal 82 is a mobile terminal app, and the wireless communication module 83 is a Wi-Fi module or a LoRa module. The remote control terminal 82 is a dedicated app running on Android or iOS systems, allowing users to log in with an account to view the current device status, historical data, remotely start and stop the device, and modify control policies. The wireless communication module 83 can be a Wi-Fi module for accessing the local area network or a LoRa module for long-distance low-power communication, depending on the scenario. The communication module connects to the intelligent analysis module 5 via a UART serial port and has a built-in authentication mechanism and communication encryption algorithm to ensure data security.

[0025] The app supports features such as a graphical interface, push notifications, and parameter curve display, enhancing the intelligence and convenience of remote management.

[0026] Preferably, the bottom of the gas-liquid mixing chamber 615 is connected to an annular gas distribution pipe 618, which is equidistantly connected to multiple microporous diffusers 617, and has a removable drain plug at its distal end. The annular gas distribution pipe 618 installed at the bottom of the gas-liquid mixing chamber 615 is made of PP or PVC material, with a diameter of approximately 20 mm, and is connected to the bottom of the mixing chamber via a heat-fusion or threaded joint. Multiple microporous diffusers 617 are equidistantly installed around the gas distribution pipe, with micropore diameters of approximately 50-100 micrometers, ensuring uniform bubble distribution and improving the oxygen dissolution efficiency in the water. The removable drain plug at the distal end of the gas distribution pipe facilitates the periodic removal of deposited impurities, maintaining system cleanliness and unobstructed gas flow. The diffusers can be made of ceramic or EPDM material, possessing corrosion resistance and high mechanical strength, suitable for long-term underwater operation.

[0027] Working Principle: The system achieves stable water quality control through a closed-loop mechanism of "real-time sensing—intelligent analysis—dynamic regulation—feedback optimization." During initial system operation, circulating water pump 62 starts, continuously supplying water from fishpond 1 to plant cultivation trough 2, and then returning it through water pipe 3, forming a stable water circulation path. Simultaneously, the first circulating pump 71 and the second circulating pump 72 start according to a set strategy, achieving local independent circulation between the fishpond and the plant cultivation trough, improving regulation accuracy. During system operation, multiple sensors in the water quality monitoring module 4 start synchronously, collecting key water quality data in real time, such as dissolved oxygen, ammonia nitrogen, turbidity, pH, temperature, and conductivity. Fishpond 1 is responsible for aquatic environmental indicators, while plant cultivation trough 2 monitors plant root zone environmental indicators. All sensors are connected to the intelligent analysis module 5 via wires, forming a high-frequency, high-resolution continuous data stream.

[0028] The intelligent analysis module 5 incorporates a dynamic decision-making algorithm. After receiving sensor data, it automatically compares it with a set threshold. Once a parameter deviates from the set value, the system immediately determines the type of intervention required and triggers the corresponding functional unit in the control module 6. For example, when the dissolved oxygen concentration drops to the lower limit threshold, the system controls the circulating water pump 612 to start, injecting water into the venturi injector 611 to form a negative pressure that draws in gas delivered by the air pump 613. The gas-water mixture is released through the gas-liquid mixing chamber 615 and multiple microporous diffusers 617 in the air distribution pipe 618, forming fine bubbles to increase the oxygen content of the water. At the same time, the intelligent analysis module 5 monitors the oxygen concentration change trend in real time and dynamically adjusts the aeration intensity and duration to avoid over-oxygenation.

[0029] If an abnormal pH value is detected, the intelligent analysis module 5 immediately activates the automatic dosing device 63, controls the metering pump 632 to draw neutralizing agent from the drug storage tank 631 at a set flow rate, injects it into the fish pond 1 through the dosing pipe 633, and monitors the pH value change until it returns to the target range; if the temperature sensor reports that the water temperature is too low, it controls the heater in the temperature control device 64 to turn on, heats to the set temperature, and then automatically turns off to ensure a suitable temperature environment for fish and plants; when the ambient light is insufficient or when operating at night, the lighting device 65 automatically lights up to simulate natural light for supplemental lighting to maintain the photosynthetic cycle of plants.

[0030] Throughout the process, all control actions are recorded in real time by the intelligent analysis module 5 and fed back to the human-machine interaction module 8. Users can view water quality data and equipment status through the display screen 81, and can also remotely issue control commands or modify parameter settings through the remote control terminal 82 (mobile App). All remote data is transmitted through the wireless communication module 83 (Wi-Fi or LoRa), realizing unattended on-site management and remote fault response.

[0031] By continuously sensing environmental changes, the system drives coordinated operation among multiple modules to achieve dynamic balance management of water quality and healthy ecosystem operation. During long-term operation, the system can also optimize its operation through data accumulation, improving control response speed and energy efficiency, and ensuring the continuous satisfaction of the dual growth needs of fish and plants.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
