Abstract
Description
Technical Field
[0001] This invention relates to the field of land-based aquaculture technology, and in particular to an intelligent water temperature control system and method for land-based aquaculture. Background Technology
[0002] Land-based recirculating aquaculture systems, as an intensive and controlled aquaculture method, can significantly increase stocking density and water recycling rate.
[0003] Water temperature is one of the most critical environmental factors affecting the growth, metabolism, immunity, and feed conversion rate of aquatic organisms. Different aquatic species and their different growth stages have specific suitable water temperature ranges (i.e., the interval between the first threshold and the second threshold). Current land-based aquaculture systems rely heavily on manual experience or simple temperature control equipment for water temperature control, making it difficult to achieve high-precision and high-stability constant or circulating temperature control. Especially when faced with external climate fluctuations, uneven heat distribution in the aquaculture pond (heat island effect), or changes in aquaculture load, water temperatures often exceed the suitable range, which can range from affecting growth to causing stress or disease outbreaks.
[0004] Therefore, there is an urgent need to invent an intelligent control method and system that can accurately and adaptively control the temperature of aquaculture water within a preset suitable range, so as to meet the core needs of efficient, stable and intelligent production in land-based aquaculture. Summary of the Invention
[0005] This invention provides an intelligent water temperature control system and method for land-based aquaculture to solve one or more technical problems encountered in the prior art.
[0006] In a first aspect, embodiments of the present invention provide an intelligent water temperature control system for land-based aquaculture, comprising: A multi-level temperature sensing network is distributed across multiple aquaculture ponds and water bodies at different depths in the land-based aquaculture workshop to collect water temperature data in real time and monitor its spatial distribution. A multimodal decision-making module with range control as its core is connected to a multi-level temperature sensing network. The multimodal decision-making module is used to receive the water temperature data and calculate the deviation and trend of the current water temperature relative to the preset suitable range. The multimodal decision-making module is used to fuse auxiliary data from water quality sensors and biological behavior monitoring devices. The multimodal decision-making module is used to generate a coordinated control strategy based on the auxiliary data and the deviation and trend of the current water temperature to maintain the water temperature within the suitable range or to make it quickly return to the range. The execution network is zonal and controllable. It includes distributed temperature control devices and water circulation disturbance devices that can act independently or collaboratively according to a strategy. It is used to perform heating, cooling or heat diffusion operations on specific areas. The execution network is communicatively connected to the multimodal decision module. The execution network is used to drive the temperature control devices and water circulation disturbance devices to converge the overall water temperature of the aquaculture pond to the preset suitable range according to the collaborative control strategy generated by the multimodal decision module.
[0007] In a preferred embodiment, the multi-level temperature sensing network includes a vertical sensor array deployed in different water layers within a single aquaculture pond and a horizontal sensor network deployed in aquaculture ponds at different geographical locations, for constructing a three-dimensional temperature field of the aquaculture water body; based on this three-dimensional temperature field, the multimodal decision module is used to identify low-temperature regions where the water temperature is below a first threshold, high-temperature regions where the water temperature is above a second threshold, and potential thermal disturbance regions with large gradient differences within the suitable range.
[0008] In a preferred embodiment, the multimodal decision-making module with interval control as its core incorporates a rule-model hybrid engine, whose decision logic includes: When the water temperature is detected to be lower than the first threshold, the heating strategy is triggered, and the water circulation disturbance device is activated based on the dissolved oxygen concentration. When the water temperature is detected to be higher than the second threshold, a cooling or natural heat dissipation strategy is triggered, and the water circulation intensity is adjusted according to the trend of ammonia nitrogen concentration change. When a large gradient difference is detected in the water temperature within the suitable range, an equalization strategy is triggered to control the water circulation disturbance device to eliminate the heat island effect and maintain the temperature uniformity within the range. All strategies reference real-time biological behavior data. When reduced feeding activity or stress behavior of abnormal clusters is detected, the multimodal decision-making model smooths the rate or magnitude of temperature control.
[0009] In a preferred embodiment, the multimodal decision module further includes an adaptive interval optimization submodule, which optimizes the values of the first threshold and the second threshold and learns the optimal control parameters for maintaining water temperature within the dynamic interval under different environmental conditions based on the aquaculture species, growth stage and historical growth performance data.
[0010] In a preferred embodiment, the distributed temperature control device in the zone-adjustable execution network includes a main heat pump unit and multiple auxiliary heating / cooling units deployed in key aquaculture ponds or specific areas within the ponds; the multimodal decision module is used to control the auxiliary units in the execution network to precisely supplement heating in low-temperature areas or locally cool high-temperature areas according to water temperature deviations, and to control the execution network to coordinate the water circulation disturbance device to promote uniform heat diffusion, so that the overall water temperature quickly and stably returns to the preset suitable range.
[0011] In a preferred embodiment, the multimodal decision module includes an edge-cloud collaborative architecture, which includes: Edge control nodes, deployed in the aquaculture workshop, are used for real-time data processing and rapid decision-making, and provide millisecond-level response to emergencies where the water temperature exceeds the preset suitable range; The cloud-based analytics platform is used to aggregate long-term data, run predictive models, predict the impact of changes in the external environment on the water temperature range in the next few hours to days, and send optimization strategies or model parameters to the edge control nodes in advance to enhance the predictability and robustness of the range control.
[0012] In a preferred embodiment, the predictive model integrated by the cloud analysis platform is used to predict the risk probability and timing of the breach of the preset suitable range by combining external weather forecasts, historical water temperature data and workshop operation logs; based on this prediction, the cloud analysis platform is used to generate forward-looking maintenance strategies including advance heat storage, pre-cooling or adjustment of circulation mode.
[0013] In a preferred embodiment, the system further includes a unified data interface for accessing various environmental sensors; the unified data interface is communicatively connected to the multimodal decision module, and is used to set the first threshold and the second threshold in the multimodal decision module through a human-computer interaction interface, or for the aquaculture management system to automatically send the first threshold and the second threshold set in the aquaculture model to the multimodal decision module through the unified data interface.
[0014] In a preferred embodiment, the system further includes an energy efficiency optimization subsystem, which is communicatively connected to the execution network. The energy efficiency optimization subsystem is used to optimize the operation combination and timing of each device in the execution network, prioritizing the scheduling of devices with high energy efficiency ratios, and optimizing energy consumption costs by utilizing time-of-use pricing policies, under the primary premise of ensuring that the water temperature is stably maintained within the preset suitable range.
[0015] Secondly, embodiments of the present invention provide a land-based aquaculture water temperature intelligent control method based on the above-mentioned system, with the core objective of maintaining the aquaculture water temperature within a preset suitable range defined by a first threshold and a second threshold, comprising the following steps: Temperature data of aquaculture water is collected in real time through a multi-level temperature sensing network, and multimodal data on water quality and biological behavior are obtained. Based on the temperature data, determine the deviation relationship between the current overall and local water temperature and the preset suitable range; By integrating the aforementioned water temperature deviation relationship, real-time water quality data, and biological behavior data, a collaborative regulation strategy is generated with the core objective of correcting deviations and maintaining range stability. The strategy is executed through a partitioned and controllable execution network, driving the distributed temperature control device and water circulation disturbance device to perform precise actions; The system continuously monitors whether the water temperature after regulation returns to and stabilizes within the preset suitable range, and collects multimodal feedback data to evaluate the control effect and iteratively optimize the decision logic.
