[0002] Deep-sea aquaculture is gradually emerging as a fishery production model with great potential. Traditional offshore aquaculture faces many difficulties, such as limited aquaculture space and natural disasters such as red tides, which greatly increase the risk of aquaculture. In contrast, deep sea areas have vast space, relatively clean and stable seawater environment, providing a new direction for the aquaculture industry. However, while deep-sea aquaculture brings opportunities, it also triggers a series of new challenges. The deep-sea environment is complex and harsh, with high water pressure, low temperature, variable salinity, and the aquaculture area is far away from the land, which makes it difficult for farmers to monitor the aquaculture status in real time as conveniently as offshore aquaculture. In the past, farmers mostly relied on regular manual inspections at sea, which not only consumed a lot of manpower, material resources and time costs, but also failed to detect sudden problems in the aquaculture process in time, such as outbreaks of fish diseases, damage to aquaculture cages, and slight deterioration of water quality. They often waited until the problems became serious before they knew about them, causing huge economic losses. Summary of the invention

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0017] In the description of the embodiments of the present invention, unless otherwise specified, "multiple" means two or more than two. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" may mean: A exists alone, A and B exist at the same time, and B exists alone.

[0018] The descriptions of "first", "second", etc. involved in the embodiments of the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the technical features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] Before presenting the embodiments, the following terms are explained.

[0021] ‌Aquaculture cage / aquaculture cage / cage: refers to a tool used for aquaculture, which is mainly composed of a frame system, a net bag, a fixing system and supporting facilities. The cage is lowered to a specified depth underwater by utilizing the interaction of the fixed platform and the characteristics of the cage itself.

[0022] Mooring rope: refers to the equipment used to fix the aquaculture cages on the berth, mainly including ropes and related mooring equipment. Its main function is to use ropes to firmly tie the aquaculture cages to the dock, mooring buoy or other fixed facilities to ensure that the aquaculture cages remain stable in wind and waves.

[0023] Bioattachment: refers to the fixation of cells or tissues on the surface of a material.

[0024] The present invention provides a monitoring device, system and method for aquaculture cages, which are respectively described below.

[0025] Figure 1 A schematic diagram of the structure of an embodiment of the monitoring device for aquaculture cages provided by the present invention is shown in FIG. Figure 1 As shown, the monitoring device 10 for aquaculture cages comprises: The monitoring module 110 is used to monitor the real-time data of the aquaculture cage, and the real-time data at least includes: the actual temperature and chlorophyll content of the flow field where the aquaculture cage is located.

[0026] Preferably, the monitoring module in this embodiment at least includes: a chlorophyll sensor for monitoring the chlorophyll content of the flow field where the aquaculture cage is located, and a sensor for monitoring the actual temperature of the flow field where the aquaculture cage is located.

[0027] Furthermore, taking a cylindrical aquaculture cage as an example, it is fixed by four mooring cables, and temperature sensors and chlorophyll sensors are installed at four positions in the aquaculture cage to monitor the temperature changes and chlorophyll content changes in the entire cage flow field. The temperature sensor records the temperature of the seawater in the sea area where the aquaculture cage is located and uploads the data to the central processing module through the transmission module.

[0028] The central processing module 120 is electrically connected to the monitoring module, and is used to determine whether the actual temperature is within the preset temperature threshold range and whether the chlorophyll content is lower than the preset minimum chlorophyll content, and when the actual temperature is within the temperature threshold range and the chlorophyll content is not lower than the minimum chlorophyll content, the detection result that the breeding environment of the current breeding cage meets the growth needs of the breeding crops is obtained, and the real-time data and the detection results are transmitted to the external terminal device.

[0029] It should be noted that chlorophyll is a key pigment for algae photosynthesis, and its content directly reflects the algae biomass. An appropriate amount of algae can provide natural food for farmed organisms and promote growth; but if the chlorophyll content in certain areas of the flow field is too low, it may mean that there is insufficient algae, resulting in a lack of food, affecting the nutritional supply of farmed organisms. Monitoring the chlorophyll content helps to identify these "nutritional blind spots" and timely supplement artificial feed or adjust the breeding density. The dynamic changes in the deep-sea flow field will affect the transport of nutrients and the distribution of algae. By monitoring the chlorophyll content, the uniformity of the nutrient supply of the flow field to the breeding area can be evaluated and the breeding layout can be optimized. In addition, excessive chlorophyll concentration is usually associated with algal blooms, and low-value areas in the flow field may be "lurking areas" before algal outbreaks. Through long-term monitoring, the temporal and spatial variation trends of chlorophyll content can be analyzed, and the migration path of algae can be predicted in combination with the flow field model, so as to intervene in advance to avoid large-scale pollution.

[0030] Specifically, Figure 2 As shown, Figure 2 The schematic diagram of the process of the aquaculture environment monitoring embodiment provided by the present invention includes: S201, temperature sensor and chlorophyll sensor regularly monitor the breeding environment data; S202, the detected data is uploaded to the central processing module for analysis through the transmission module; S203, the central processing module obtains the temperature and chlorophyll changes within the period according to calculation and analysis; S204, judging whether the breeding environment is suitable according to the minimum value of the preset condition; S205, uploading the suitability determination result to the terminal.

[0031] Compared with the prior art, the present invention provides a monitoring device for aquaculture cages, which monitors various data of the cages in real time through a monitoring module, and uploads the data to a central processing module for analysis and calculation, thereby obtaining a detection result of whether the current aquaculture environment of the aquaculture cages meets the growth needs of the aquaculture crops. At the same time, the detection data and the detection results are remotely transmitted to the terminal device, thereby helping the user to obtain the aquaculture situation in real time and make timely decisions. The present invention uses information in an unmanned manner to monitor the aquaculture environment in real time, effectively improving the real-time and convenience of monitoring deep-sea aquaculture conditions, thereby solving the technical problem that the prior art cannot conveniently monitor the aquaculture situation in real time. It should be noted that in the process of deep-sea aquaculture, in addition to the impact of the aquaculture environment on the aquaculture crops, the potential safety hazards of the aquaculture cages themselves also need to be paid attention to. In order to monitor the potential safety hazards of the cages themselves, in some embodiments of the present invention, the monitoring module 110 also includes: A stress sensor, used to monitor the tension data of the mooring rope of the aquaculture cage and send the tension data to the central processing module 120; The central processing module 120 is also used to compare the tension data with the preset cable break tension data, and determine that there is no safety hazard in the breeding cage when the tension data is not greater than the preset cable break tension data.

[0032] Furthermore, if Figure 3 As shown, Figure 3 The schematic diagram of the process of the mooring rope tension data monitoring embodiment provided by the present invention includes: S301, the stress sensor regularly detects the change data of the tension of the mooring rope; S302, the detected data is uploaded to the central processing module through the transmission module for analysis; S303, the central processing module compares the actual data with the maximum tension data of the cable; S304: If the actual data is less than the maximum tension data of the cable, the mooring is safe; S305, if the actual data is greater than the maximum tension data of the cable, the mooring is at risk of breaking, and the process goes to step S306; S306. Immediately send an early warning signal to the terminal through the transmission module. It should be noted that while monitoring the aquaculture environment and aquaculture cages for potential safety hazards, the present invention also takes into account the actual situation that serious biological attachment to the aquaculture cages will squeeze the growth space of the aquaculture organisms. In order to remove these biological attachments in a timely manner to further improve the practicality of the present invention, Figure 4 In some embodiments of the present invention, the monitoring device 10 further includes: Biological attachment cleaning module 130, installed on the surface of the net of the aquaculture cage, is used to clean the biological attachment on the net; The display and alarm module 140 is electrically connected to the central processing module 120, and is used to obtain and display real-time data and detection results, and to generate a warning signal when it is determined based on the detection results that the current breeding environment of the breeding cage does not meet the growth needs of the breeding crops and / or there are safety hazards in the breeding cage.

[0033] It should be noted that the display and alarm module 140 of this embodiment is used for information display at the breeding site, while the external terminal device 20 is mainly used for remote information display.

[0034] The transmission module 150 is electrically connected to the monitoring module 110, the central processing module 120 and the display and alarm module 140, and is also in communication connection with the biological attachment cleaning module 130 and the external terminal device 20, and is used to transmit the real-time data monitored by the monitoring module to the central processing module, and transmit the detection results analyzed by the central processing module to the display and alarm module, and also send the real-time data, the detection results and the warning signal generated by the display and alarm module to the external terminal device; The power supply module is electrically connected to the monitoring module, the central processing module, the display and alarm module, the transmission module and the biological attachment cleaning module for supplying power.

[0035] In some embodiments of the present invention, the biofouling cleaning module 130 includes: The high-pressure water spray module 131 is used to spray water with pressurized seawater to remove biological attachments on the aquaculture cages.

[0036] Furthermore, in order to increase the cleaning strength and prevent the occurrence of cleaning dead corners, in some embodiments of the present invention, the biological attachment cleaning module further includes: The displacement module 132 includes two sets of mutually perpendicular gear combinations, which are used to realize the displacement module with two degrees of freedom of front-back and left-right displacement in the plane formed by the net. Each gear combination includes a plurality of gears arranged side by side. Four circular buckles are evenly distributed on the top cylindrical surface of each gear. The diameter of each circular buckle is consistent with the diameter of the net rope of the net, ensuring that the circular buckle can tightly wrap the net rope, and the spacing between any two adjacent circular buckles is consistent with the diameter of the mesh on the surface of the net. The high pressure water spray module is mechanically connected to the gear combination of the displacement module through the gear shaft.

[0037] In order to enable the aquaculture monitoring to operate normally and stably and ensure the accuracy of the monitoring results, in some embodiments of the present invention, the monitoring module 110 further includes: an underwater camera, installed on the biological attachment cleaning module 130, for taking pictures including the aquaculture cage and / or the aquaculture crops in the aquaculture cage in real time; The central processing module 120 is also used to compare and analyze the image with the preset reference image to obtain a first change value of the volume change of the cultured crops in the cage and a second change value of the diameter change of the rigid rod on the culture cage, and then judge whether the first change value is less than the preset volume change threshold and whether the second change value is less than the preset diameter change threshold. When the first change value is not less than the volume change threshold, a judgment result that the growth of the cultured crops is normal is obtained and the judgment result is sent to the external terminal device 20 through the transmission module 150. When the second change value is not less than the diameter change threshold, a cage cleaning instruction is sent to the biological attachment cleaning module 130 through the transmission module 150 to clean the culture cage with pressurized water.

[0038] Furthermore, if Figure 6 As shown, Figure 6 The schematic diagram of the process of the underwater camera monitoring embodiment provided by the present invention includes: S601, underwater cameras take pictures of aquaculture crops and aquaculture cages regularly; S602, uploading the photo to the central processing module through the transmission module for image comparison and analysis; S603, analyzing and obtaining the change of the cage diameter, i.e., the growth of the biological attachment; S604, analyzing the volume change of the crop during the breeding cycle and uploading it to the terminal; S605, when the biological adhesion degree reaches a critical value, a cleaning instruction is sent to the biological adhesion cleaning module through the transmission module; S606, the biological attachment cleaning module uses high-pressure seawater to clean the surface of the cage.

[0039] It should be noted that the high-pressure water spray module 131 can also rotate within the plane in which it is located to achieve cleaning in two different directions, longitudinal and transverse. When used in conjunction with the displacement module 132, the cleaning area can be increased, and most of the biological attachments in the aquaculture cages can be effectively cleaned. At the same time, since the underwater camera is installed on the biological attachment cleaning module, the underwater camera can also move with the biological attachment cleaning module, so during the cleaning process, it can monitor in real time the areas of the aquaculture cages that have not been cleaned or have poor cleaning effects, thereby reducing cleaning blind spots.

[0040] In a second aspect, the present invention further provides a monitoring system for aquaculture cages, comprising: A monitoring device 10 for aquaculture cages as described in any one of the above-mentioned device items; The terminal is communicatively connected with the transmission module 150 of the monitoring device 10, and is used to receive the real-time data monitored by the monitoring module 110, the detection results analyzed by the central processing module 120, and the early warning signal generated by the display and alarm module 140, and simultaneously display the real-time data and the detection results, and issue an alarm according to the early warning signal.

[0041] like Figure 7 In a third aspect, the present invention further provides a method for monitoring aquaculture cages, which is applied to a monitoring device for aquaculture cages as described in any one of the above-mentioned device items, comprising: S701, monitoring the real-time data of the aquaculture cage based on the monitoring module, the real-time data at least including: the actual temperature and chlorophyll content of the flow field where the aquaculture cage is located; S702. Based on the central processing module, determine whether the actual temperature is within the preset temperature threshold range and whether the chlorophyll content is lower than the preset minimum chlorophyll content. When the actual temperature is within the temperature threshold range and the chlorophyll content is not lower than the minimum chlorophyll content, obtain the detection result that the breeding environment of the current breeding cage meets the growth needs of the breeding crops, and transmit the real-time data and the detection results to the external terminal device.

[0042] like Figure 8 In some embodiments of the present invention, the method for monitoring aquaculture cages further comprises the following steps: S801, monitoring the tension data of the mooring rope of the aquaculture cage based on the monitoring module and sending the tension data to the central processing module; S802: Based on the central processing module, the tension data of the mooring rope of the aquaculture cage is compared with the preset cable break tension data, and when the tension data is not greater than the cable break tension data, it is determined that there is no safety hazard in the aquaculture cage.

[0043] like Fig. 9 In some embodiments of the present invention, the method for monitoring aquaculture cages further comprises the following steps: S901, taking pictures including aquaculture cages and / or crops cultured in aquaculture cages in real time using an underwater camera; S902. Based on the central processing module, the image taken by the underwater camera is compared and analyzed with the preset reference image to obtain a first change value of the volume change of the cultured crops in the cage and a second change value of the diameter change of the rigid rod on the culture cage, and then the first change value is compared with the preset volume change threshold and the second change value is compared with the preset diameter change threshold. When the first change value is not less than the volume change threshold, a judgment result is obtained that the growth of the cultured crops is normal. When the second change value is not less than the diameter change threshold, a cage cleaning instruction is sent to the biological attachment cleaning module to clean the cage.

The method for monitoring aquaculture cages according to claim 8, characterized in that: The monitoring method of the breeding cage also includes the following steps: Using underwater cameras to take real-time pictures including aquaculture cages and / or crops cultured in aquaculture cages; Based on the central processing module, the picture taken by the underwater camera is compared and analyzed with the preset reference picture to obtain a first change value of the volume change of the cultured crops in the cage and a second change value of the diameter change of the rigid rod on the culture cage. Then, the first change value is compared with the preset volume change threshold and the second change value is compared with the preset diameter change threshold. When the first change value is not less than the volume change threshold, a judgment result is obtained that the growth of the cultured crops is normal. When the second change value is not less than the diameter change threshold, a cage cleaning instruction is sent to the biological attachment cleaning module to clean the cage.
