Next, a method for hydroponic cultivation according to an embodiment of the present invention will be described. 7 is a flowchart for explaining a method for hydroponic cultivation according to an embodiment of the present invention. 8 and 9 are screen examples for explaining a method for hydroponic cultivation according to an embodiment of the present invention.

Referring to FIG. 7 , the controller 180 of the hydroponics apparatus 100 collects temperature, humidity and illuminance through the sensor unit 130 for each of the plurality of compartments 30a, 30b, 30c in step S110, and a camera unit The tray is photographed through 120 to monitor the plants on the tray.

During such monitoring, the control unit 180 stores the nutrient solution and moisture supply cycle for each plant in the storage unit 170, and in step S120, according to the nutrient solution and moisture supply cycle for each plant, the nutrient solution for each of the plurality of compartments 30a, 30b, 30c and it is determined whether the time of supplying moisture has arrived.

As a result of the determination in step S120, when the time to supply the nutrient solution and moisture has arrived, the controller 180 proceeds to step S130 to control the supply of the nutrient solution and moisture to the plant. That is, the controller 180 may control the length of the wire 61 by controlling the motor 62 of the lift unit 60 through the driving unit 160 according to the nutrient solution and moisture supply cycle for each plant. Accordingly, as shown in (A) of Figure 3, by reducing the length of the wire 61 to raise the tray 50 connected to the wire 61, or as shown in Figure 3 (B), the wire It is possible to lower the tray 50 connected to the wire 61 by increasing the length of the 61 . As shown in (B) of FIG. 3 , when the tray 50 descends and floats on the nutrient solution and moisture of the water tank 40 , the roots exposed at the bottom of the tray 50 are moved to the water tank 40 . of nutrient solution and water. Accordingly, the plant can be supplied with nutrient solution and moisture. In addition, as shown in FIG. 3A , when the tray 50 rises and the roots are exposed from the nutrient solution and moisture in the water tank 40 , oxygen supply to the roots becomes smooth.

As a result of the determination in step S120, if it is not the time to supply the nutrient solution and moisture, the controller 180 proceeds to step S140 to identify whether there are harvestable objects among the plurality of plants of the plant. In this case, the control unit 180 may photograph the plant in the tray 50 through the camera unit 120 and, according to the shape of the photographed plant, identify whether a harvestable entity exists among a plurality of entities of the plant. . For such identification, the controller 180 may use an artificial neural network that identifies harvestable objects through deep learning. Such an artificial neural network may be exemplified by a convolutional neural network (CNN).

As a result of the identification in step S140 , if there is a harvestable object, the controller 180 performs a harvest guidance process in step S150 .

In step S150 , the controller 180 projects the identification image representing the silhouette of the object on the door 10 through the projection unit 150 so that the harvestable object is identified from other objects. For example, referring to FIG. 8 , it is assumed that the first object en1 is a harvestable object. Then, the controller 180 projects the identification image si representing the silhouette of the first object en1 on the door 10 through the projection unit 150 . Accordingly, since the user's gaze is directed toward the door 10 , the user may recognize that the arithmetic object en1 is the first object en1 through the identification image si projected on the door 10 .

In addition, in step S150 , the controller 180 projects a guide image for guiding a method of harvesting a harvestable object on the door 10 through the projection unit 150 . For example, referring to FIG. 8 , it is assumed that the second entity en2 is a harvestable entity. Also, it is assumed that when the second object en2 is harvested, a portion of the first display line L1 should be cut with scissors. In this case, the controller 180 projects the guide image gi including the scissors and the guide line for guiding the cutting of the first display line L1 with the scissors through the projection unit 150 on the door 10 . Accordingly, since the user's gaze is directed toward the door 10 , the user may recognize the harvesting method for the second object en2 through the guide image gi projected on the door 10 .

In step S150, the controller 180 generates a synthetic identification image by synthesizing a virtual silhouette of the object with the image captured by the camera unit 120 according to the augmented reality technique so that the harvestable object is identified from other objects. For example, an image obtained by photographing a plant by the camera unit 120 is shown in FIG. 9(A). In this image, it is assumed that the third entity en3 is a harvestable entity. Then, the controller 180 generates a virtual silhouette of the corresponding entity en3, synthesizes the generated virtual silhouette asi with an image photographed of a plant, and generates a synthetic identification image as shown in (B) of FIG. 9 . Then, the controller 180 transmits the generated synthetic identification image to the user device 200 through the communication unit 110 .

In addition, in step S150, the controller 180 generates a synthetic guide image by synthesizing a guide image for guiding a method of harvesting a harvestable object with an image of a plant photographed according to an augmented reality technique. For example, an image obtained by photographing a plant by the camera unit 120 is shown in FIG. 9(A). In this image, it is assumed that the third entity en3 is a harvestable entity. Also, it is assumed that a predetermined portion must be cut with scissors when the third object en3 is harvested. In this case, the controller 180 synthesizes a guide image gi including scissors and a guide line for guiding the cutting of the corresponding part with scissors into an image photographed of a plant to produce a synthetic guide image as shown in (B) of FIG. 9 . create Then, the controller 180 transmits the generated synthetic guide image to the user device 200 through the communication unit 110 .

As a result of the determination in step S140, if there is no harvestable object, the controller 180 proceeds to step S160 to determine whether it is a tray replacement time. At this time, the controller 180 may photograph the tray 50 through the camera unit 120 , and determine the tray replacement time according to the number and shape of the plants in the photographed tray. As an example, when there are only fewer than a predetermined number of plants, it may be determined that the tray replacement should be made. Also, as another example, when most of the plants are harvested and there is no plant to be harvested, it may be determined that the tray replacement should be made.

As a result of the determination in step S160, when the time for replacing the tray arrives, the control unit 180 opens an image for identifying the compartment in which the tray to be replaced is disposed among the plurality of compartments through the projection unit 150 in step S170 to be distinguished from other compartments. (10) is projected. In addition, the controller 180 may generate an image for identifying a compartment in which a tray to be replaced is disposed in step S170 , and transmit the generated image to the user device 200 .

Here, the recording medium may include a program command, a data file, a data structure, etc. alone or in combination.

Such hardware devices may be configured to operate as one or more software modules to perform the operations of the present invention, and vice versa.

Although the present invention has been described above using several preferred embodiments, these examples are illustrative and not restrictive. As such, those of ordinary skill in the art to which the present invention pertains will understand that various changes and modifications can be made in accordance with the doctrine of equivalents without departing from the spirit of the present invention and the scope of rights set forth in the appended claims.
