[0002] With the growth of global population and the improvement of people's living standards, the demand for high-quality and high-safety marine products is increasing.

[0003] Suspended aquaculture technology is an intensively managed, high-yield, efficient, and eco-friendly aquaculture technology. This technology uses floating eco-barrels to allow fish to automatically float up or down as the water level changes, thereby resisting the risks brought about by rapid changes in water levels in summer. In addition, fry of different species and sizes can be cultured independently in separate barrels, which is convenient for salvage and management. It also makes feeding and disease prevention more precise and scientific, and maximizes the survival rate of aquaculture.

[0004] However, most existing suspended aquaculture technologies have problems such as complex transmission structure, high energy consumption, and poor stability, making it difficult to meet the aquaculture needs of high-standard marine products. Summary of the invention

[0005] In view of the above analysis, the present application aims to propose a magnetic suspension aquaculture device, method and system for high-standard marine products to solve at least one of the above problems.

[0015] Furthermore, the magnetic levitation control device is used to determine the optimal breeding environment parameters according to the movement state of the marine product and display them to the user; and to generate the control instructions according to the position parameters input by the user.

[0028] The use of magnetic levitation technology makes it possible for there to be no contact between the suspension net and the cavity, so there is no need to set up complex transmission components and support structures to avoid maintenance costs caused by friction and wear and pollution caused by wear of mechanical structures.

[0033] In order to enable those skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the technical solutions in one or more embodiments of this specification will be clearly and completely described below in conjunction with the drawings in one or more embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of them. Based on one or more embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this document.

[0034] like Figure 1As shown, an embodiment of the present application provides a magnetic levitation aquaculture device for high-standard marine products, including: a sensor, a cavity, a suspension net, a magnetic levitation control device and a magnetic levitation track. The suspension net and the cavity are not in contact. Sensors are arranged on the suspension net and the cavity to collect the aquaculture environment parameters and the movement state of the marine products in the cavity. The magnetic levitation control device is used to send control instructions to the magnetic levitation track according to the aquaculture environment parameters and the movement state of the marine products. The magnetic levitation track is arranged under the suspension net to control the suspension net to move up and down or remain stationary according to the control instructions.

[0035] In the embodiment of the present application, the magnetic levitation technology can prevent the suspension net from contacting the cavity, so there is no need to set up an additional transmission device to assist the suspension net to move up and down. The transmission device will experience equipment wear during operation, so the technical solution of the present application can avoid losses caused by equipment wear. The transmission device will overcome friction to do work during operation, which means that the transmission device requires more energy, so the technical solution of the present application has an energy-saving effect. In addition, based on magnetic levitation technology and high-precision sensors, when disturbed by external factors, the position and height of the suspension net can be accurately controlled to ensure the stable operation of the breeding device. For example, the sensor detects that the current position has a low oxygen content, which is not conducive to the activity of marine products. The magnetic levitation track is used to control the suspension movement to transfer the marine products to a position with a higher oxygen content.

[0036] It should be noted that since the suspended net does not contact the cavity, the size of the suspended net should be smaller than the cross-section of the cavity, but the size of the suspended net should match the cross-section of the breeding area to ensure the breeding effect. For example, when the marine product is fish, the size of the suspended net should be larger than the cross-section of the breeding area, and ensure that the fish cannot pass through the gap between the suspended net and the cavity. When the marine product is shellfish, the shellfish is directly placed on the suspended net. Since the shellfish has less space to move, the minimum size of the suspended net can be equal to or slightly smaller than the cross-section of the breeding area. Sensors are placed on the suspended net or on the cavity according to their functions. For example, equipment with a shooting function is usually placed on a suspended net for easy shooting. A displacement sensor can be set at the bottom of the cavity to control the position of the suspended net. Sensors for measuring temperature and light intensity can be set on the side walls of the cavity to determine in real time the position suitable for marine products in the cavity.

[0037] In the embodiment of the present application, the suspended net divides the cavity into two parts, one part is suitable for marine products, and the other part is not suitable for marine products. It should be noted that the suitability and unsuitability here are only relative, not absolute, and it depends on the breeding status of the marine products. For example, marine products need sufficient light. At this time, the well-lit area in the cavity is the part suitable for marine products, and the insufficiently lit area is the part not suitable for marine products. However, if the marine products need to be protected from light, the well-lit area in the cavity becomes the part not suitable for marine products, and the insufficiently lit area is the part suitable for marine products.

[0038] The sensor detects the aquaculture environment in the cavity to determine whether the current area is suitable for marine products. If so, the suspension net remains stationary. Otherwise, the staff needs to redefine the part of the cavity that is suitable for marine products. After redefining the part that is suitable for marine products, the magnetic suspension track is used to control the suspension net to rise or fall, so as to transfer or drive the marine products to the part that is suitable for marine products.

[0039] In the embodiment of the present application, the magnetic levitation control device specifically includes: an MCU processor (Microcontroller Unit) and an electromagnetic relay. The MCU processor is used to process the data collected by the sensor, such as determining whether the corresponding parameter exceeds a threshold, or processing the collected image and performing image recognition.

[0040] In the embodiment of the present application, in order to determine the status of marine products from multiple dimensions and to facilitate the adjustment of the position of the suspended net, a variety of sensors are provided, including:

[0041] Image sensors can obtain the status of marine products through images, for example, whether there are any abnormalities in fish.

[0042] Temperature sensor: Water temperature has a profound impact on the growth of marine products. Therefore, a temperature sensor is set to collect the temperature of the breeding environment to determine whether the temperature is suitable for breeding marine products.

[0043] Water quality sensor: A large number of marine products gather in a certain area, producing a large number of metabolites, which may be detrimental to the growth of marine products. Water quality sensors can be used to obtain in real time whether the metabolites in the corresponding area exceed the standard. Once the standard is exceeded, the marine products in the area will be transferred to other areas, and then the area will be cleaned to ensure a good breeding environment.

[0044] Flow rate sensor, the water flow rate in the cavity has an impact on the growth of marine organisms. Specifically, the flow rate can stimulate the swimming behavior of fish, stimulate their activity and desire to swim, thereby affecting digestion and metabolism, and then affecting the survival rate of fish. Therefore, the flow rate sensor is used to monitor the water flow rate in the cavity in real time to ensure the healthy growth of marine products.

[0045] Light intensity sensor, suitable light can promote the metabolism of aquatic animals, accelerate growth rate, improve feed utilization, biological immunity and reproductive capacity. Therefore, the light intensity sensor is used to monitor the light intensity in the cavity in real time to promote the growth of marine products.

[0046] Pressure sensor,When breeding deep-sea fish, it is necessary to maintain a certain water pressure to ensure the quality of the fish meat. Therefore, a pressure sensor is used to determine the water pressure in the cavity in real time.

[0047] The height sensor is used to determine the current position of the suspended net.

[0048] The displacement sensor is used to determine whether the suspended net moves to the specified position.

[0049] In the embodiment of the present application, the aquaculture environment parameters include: one or more of the water temperature in the cavity, the water component content, the flow rate, the light intensity, the seawater pressure and the displacement of the suspension net. The movement state of the marine product includes: one or more of the movement state, the static state, the gathering area selection and the feeding rule. The movement state of the marine product is mainly obtained in the form of video.

[0050] In the embodiment of the present application, in order to ensure high-quality data acquisition, the sensors on the suspension net are evenly arranged on the suspension net. For example, for a rectangular suspension net, cameras can be arranged at the four corners of the rectangle to ensure a more comprehensive and objective determination of the movement state of the marine organisms.

[0051] In the embodiment of the present application, there are two ways to control the movement of the suspension net:

[0052] In the first case, the magnetic levitation control device is used to determine whether the environmental parameters exceed the preset threshold; when the threshold is exceeded, an alarm is issued; and a control instruction is generated according to the position parameters input externally. In the first case, when the magnetic levitation control device determines that the current breeding environment is not suitable for marine products, an alarm is issued immediately. After receiving the alarm, the relevant personnel redetermine the area suitable for breeding marine products. After that, the relevant personnel send the position parameters of the redetermined area to the magnetic levitation control device. The magnetic levitation control device generates a control instruction based on the position parameters to facilitate moving the suspension net to the corresponding position.

[0053] In the second case, the magnetic levitation control device is used to determine the optimal breeding environment parameters according to the movement state of the marine product and display them to the user; and generate control instructions according to the position parameters input by the user. In the second case, the magnetic levitation control device evaluates what kind of environment the marine product needs based on the data collected by the sensor, and displays the corresponding environment to the user. The user determines the new breeding area based on the environmental parameters displayed by the magnetic levitation control device. After that, the user sends the location information of the new breeding area to the magnetic levitation control device. The magnetic levitation control device generates control instructions based on the position parameters to facilitate moving the suspension net to the corresponding position.

[0061] Step 2: The magnetic levitation control device returns the request information to the user according to the aquaculture environment parameters and the movement status of the marine product.

[0062] In the embodiment of the present application, the return request information may be to issue an alert to the user or to directly display to the user the optimal environment required for the marine product.

[0063] Step 3: The magnetic levitation control device generates a control instruction according to the position information input by the user.

[0064] In the embodiment of the present application, the location information is the information of the floating net moving to the destination, which may be the height or the distance.
