[0039] With global population growth, the demand for food and cash crops is increasing year by year, but land and water resources are limited. Hydroponics, as an important method of modern agriculture, has been widely used in the cultivation of vegetables, flowers, and cash crops due to its water-saving, high-efficiency, soil-free, and highly controllable characteristics. Traditional hydroponic systems mainly rely on fixed nutrient concentration control, making it difficult to accurately meet the individual needs of different plants. The lack of real-time feedback mechanisms and precise control methods can easily lead to nutrient waste or poor plant growth.

[0040] To address the aforementioned issues, this embodiment provides a personalized hydroponic management system. The personalized hydroponic management system includes a hydroponic unit, which includes a hydroponic container 11 for holding nutrient solution, a container cover 12 placed on the hydroponic container 11, a nutrient solution adding pipe 13 connected to the hydroponic container 11, a drainage pipe 14 connected to the hydroponic container 11, and an image capturing component positioned above the hydroponic container 11 and the container cover 12.

[0041] The hydroponic container 11 includes a semi-enclosed shell with an opening at the top, and the interior of the shell has a space for holding nutrient solution; a container cover 12 is disposed on the top of the shell, and a planting hole 15 is provided on the container cover 12; an addition controller 131 is provided on the nutrient solution addition pipe 13, which is used to control the addition of nutrient solution into the hydroponic container 11; a drainage controller 141 is provided on the drainage pipe 14, which is used to control the discharge of water inside the hydroponic container 11 into the drainage pipe 14; an image capturing component is used to acquire images of the hydroponic container 11 and the area above the container cover 12.

[0042] In this embodiment, as Figure 1 , Figure 5 , Figure 9, Figure 10 As shown, the hydroponic container 11 can be a hollow container with one open end, and can be rectangular, circular, or other shapes. The container cover 12 and the planting holes 15 provided on the container cover 12 are used to place planting baskets. Each planting hole 15 can hold one planting basket. The planting basket is a specially designed container used to fix the plant and allow the roots to penetrate through the bottom of the container into the nutrient solution to absorb water and nutrients. In some embodiments, the nutrient solution adding pipe 13 can be an independent pipe, with one end of the pipe connected to a container for holding the corresponding nutrient solution. In specific implementations, a liquid pump can also be connected to pump the nutrient solution from the container into the pipe.

[0043] The personalized hydroponic management system also includes a controller connected to an image capturing component, capable of acquiring images and analyzing the crop status within them. The controller is also connected to an add controller 131 and a drain controller 141, for adding the corresponding nutrient solution to the hydroponic container 11 and draining all or part of the nutrient solution from the hydroponic container 11.

[0044] The added controller 131 can be a solenoid valve controlled by an electrical signal, which can control the opening or closing of the solenoid valve.

[0045] In some embodiments, the inlet of the drainage pipe 14 is located at the bottom of the hydroponic container 11, which is beneficial to drain all the nutrient solution inside the hydroponic container 11 in some cases.

[0048] In this embodiment, as Figure 5 , Figure 9 , Figure 10 As shown, this embodiment includes three nutrient solution addition pipes 13, and the controller is a solenoid valve. The controller is installed on the shell on the side of the hydroponic container 11. In the specific implementation process, four, five or more nutrient solution addition pipes 13 can be set according to the characteristics of the crop.

[0049] In some embodiments, the plurality of nutrient solution addition pipes 13 are respectively used to add aqueous solutions of one or more elements selected from nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, molybdenum, and chlorine.

[0050] Furthermore, a liquid level sensor 21 is also provided inside the hydroponic container 11, which is used to detect the liquid level of the nutrient solution inside the hydroponic container 11.

[0052] In this embodiment, as Figure 5 , Figure 10 , Figure 11 As shown, the liquid level sensor 21 can be a float-type liquid level sensor or a capacitive liquid level sensor. This embodiment uses a float-type liquid level sensor 21. The float floats on the surface of the nutrient solution, and the height of the float changes with the liquid level, thereby detecting the liquid level of the nutrient solution and determining whether there is too much or too little nutrient solution.

[0053] In some embodiments, the liquid level sensor 21 is connected to the controller, and the controller can automatically add nutrient solution according to the electrical signal of the liquid level sensor 21 and the preset nutrient solution formula.

[0054] Furthermore, a hydroponic environment sensor 22 is also provided inside the hydroponic container 11, which is used to detect the parameters of the nutrient solution inside the hydroponic container 11.

[0055] The hydroponic environment sensor 22 is used to convert nutrient solution parameters into electrical signals, and an environmental signal connector connected to the hydroponic environment sensor 22 is provided on the outside of the hydroponic container 11.

[0056] In this embodiment, the hydroponic environment sensor 22 can be a sensor for detecting the conductivity of the nutrient solution or a sensor for detecting the pH value of the nutrient solution.

[0057] In this embodiment, the hydroponic environment sensor 22 is a TDS sensor, which is used to detect the total dissolved solids content in water.

[0058] A Total Dissolved Solids (TDS) sensor is a device used to measure the total dissolved solids content in water. Its core function is to indirectly reflect the total concentration of dissolved inorganic salts, minerals, ions, and other substances in water by detecting the water's conductivity. In hydroponic systems, TDS sensors are a key tool for monitoring and regulating nutrient solution concentration, directly affecting the efficiency and health of plant growth.

[0059] Furthermore, the personalized hydroponic management system includes multiple hydroponic units; the image capturing component includes an image acquisition unit 23 for capturing images, a moving track, and a drive device 25 for moving the acquisition unit 23 on the moving track.

[0060] The drive device 25 includes a strip groove that can be connected to the moving track, a driver 32 that can contact the moving track, and a locking assembly 33 for locking the drive device 25 onto the moving track. The locking assembly 33 includes a button on the top of the drive device 25 and an elastic member 34 inside the drive device 25. The elastic member 34 can push the locking assembly 33 to move along the height direction of the drive device 25.

[0061] The acquisition unit 23 is mounted on the drive device 25, which is detachably connected to the moving track. The driver 32 enables the drive device 25 and the acquisition unit 23 to move along the length of the moving track.

[0062] In this embodiment, as Figure 1 As shown, the personalized hydroponic management system includes multiple hydroponic units, meaning multiple hydroponic units are set on the same platform. The arrangement can be side-by-side along the length, side-by-side along the width, or arranged in a rectangular array. In this embodiment, they are arranged side-by-side along the length. Each hydroponic unit includes a hydroponic container 11, and two container covers 12 are placed side-by-side on the container 11. A moving track is set above the hydroponic unit, and a drive device 25 is matched with the moving track, allowing the drive device 25 to slide on the track. A data acquisition unit 23 is mounted on the drive device 25 and is used to capture images of the crops on the hydroponic container 11.

[0063] like Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the strip groove is a slot opened on the side of the drive device 25. The moving track can be locked in the strip groove. The driver 32 is located inside the drive device 25. When the driver 32 is working, it can drive the drive device 25 to move along the length direction of the strip groove. The locking assembly 33 is used to connect the drive device 25 to the moving track.

[0064] Furthermore, the moving track is a cable, which includes a parallel first cable 41 and a second cable 42; the driving device 25 is provided with two strip grooves, namely a first strip groove 43 and a second strip groove 44, which can respectively engage the first cable 41 and the second cable 42.
