The controller 130 receives information of some or all of the temperature, humidity and CO2 of the plant factory, and controls the cultivation environment of the crop based on the received information and the predetermined cultivation conditions. That is, the controller 130 compares and analyzes the sensing information collected by using the sensor unit 140 in the multi-stage cultivation apparatus 100 with the cultivation conditions such as temperature, humidity, CO 2, and culture medium set in the controller 130. The control command is generated based on the analysis result and transmitted to the air conditioning unit 110, the water supply unit 120, and the lighting unit 170.

On the other hand, the cultivation conditions of the crops previously set in the controller 130 according to an embodiment of the present invention is learning that learning the growth data according to the cultivation conditions for each crop cultivated in the plant, the setting data manually set by the user It includes data of any one of the data and cultivation conditions for the cultivation of a new crop estimated from the controller 130. That is, when the user directly sets the cultivation conditions, the controller 130 controls the cultivation environment of the crop according to the cultivation conditions selected by the user, or according to whether or not the cultivation of the crop transplanted to the multi-stage cultivation apparatus 100. Control the cultivation environment of the crop based on the learned learning data, or control the cultivation environment based on the optimal cultivation conditions for the cultivation of new crops estimated based on the learning data.

On the other hand, the controller 130 according to an embodiment of the present invention stores the learning data learning the growth data according to the cultivation conditions for each crop in the plant factory, based on the stored learning data when a new crop is transplanted to the cultivation bed Estimate the optimal growing conditions for growing new crops and control the growing environment based on the estimated growing conditions.

In this case, the learning data stored in the controller 130 refers to data for learning the growth data according to the cultivation conditions for each crop in the plant factory. That is, the controller 130 grows a crop based on a predetermined growing condition, and receives growth data of the crop using a user input or an image photographing device 180. On the other hand, the growth data of the crop includes information such as the growth and yield of the crop according to the predetermined growing conditions. Subsequently, the controller 130 analyzes the result of the growth data through the process of learning the received growth data, and determines that the growth data of the cultivated crop satisfies a predetermined threshold based on a predetermined cultivation condition. Store the set cultivation condition as learning data. Meanwhile, the controller 130 grows a crop based on a growing condition set by a user while a predetermined amount of learning data is collected. In this case, a certain amount of learning data means, but not necessarily limited to, the amount of data that can be inferred when the new crop is transplanted, the growing conditions of the new crop.

On the other hand, when the controller 130 analyzes the result of the growth data through the process of learning the received growth data, and determines that the growth data of the grown crops does not satisfy the preset threshold based on the predetermined growing condition, Based on the result of the growth data of the crop, the pre-set cultivation conditions are supplemented, and the supplemented data is stored as learning data. In this case, the controller 130 supplements the predetermined growing condition, first analyzes the result of the growth data of the crop, and extracts an error value obtained by converting the difference between the analyzed growth data and the predetermined threshold as a percentage. On the other hand, the controller 130 is set to match the complementary value according to the error range, the controller 130 to determine the complementary value corresponding to the calculated error value, based on the determined complementary value cultivation conditions To complement. At this time, the complementary value set according to the error range includes + or-value of the cultivation conditions such as temperature, humidity, CO2, roughness and culture medium.

For example, the controller 130 analyzes the result of the growth data of the crop through the learning process, and when the analysis result determines that the result of 80% of the preset threshold is achieved, the complement value matching the error value of 20% Identify and supplement the pre-established cultivation conditions based on the identified complementary values. Similarly, when an error value of 30% occurs, the complementary value matching the error value of 30% is identified, and the preset cultivation condition is compensated based on the identified complementary value.

The complementary value set according to the error range in the controller 130 is a value arbitrarily set by the user, but is not necessarily limited thereto, and is estimated by the controller 130 learning growth data for a plurality of crops. It can be set through a variety of methods.

To control the cultivation environment. That is, the controller 130 determines whether a new crop is transplanted to the cultivation bed based on an input signal of the user or an image received from the image photographing device 180, and when it is determined that the new crop is transplanted, the controller 130 stores the stored learning data. Estimate the optimal cultivation conditions for the cultivation of new crops. On the other hand, the learning data stored in the controller 130 is stored in a group according to the characteristics of the pre-cultivated crops, and the controller 130 determines the group to which the crop belongs when a new crop is transplanted. Thereafter, the controller 130 analyzes the learning data of the group to which the crop belongs, estimates an optimal cultivation condition for the cultivation of a new crop in the plant factory, and a control command for controlling the cultivation environment based on the estimated cultivation conditions. Create For example, when a new crop A is transplanted into the multi-stage cultivation apparatus 100, the controller 130 determines a group to which crop A belongs among previously stored learning data. Then, by analyzing the learning data of the group belonging to Crop A to extract the average value of the cultivation conditions, such as temperature, humidity, CO2, roughness and culture medium, the average value of the extracted cultivation conditions as the optimum cultivation conditions for the cultivation of Crop A Estimate. That is, by estimating the cultivation conditions of the new crops based on the learning data of the crops satisfying the preset thresholds, the new crops also provide the cultivation conditions that induce them to meet the preset thresholds.

On the other hand, the controller 130 receives the growth data of the new crop cultivated based on the estimated cultivation conditions, and if it is determined that the growth data of the new crop does not satisfy the preset threshold, the controller 130 outputs the result of the growth data of the new crop. Complement the estimated cultivation conditions on the basis of the basis, and stores the supplemented data as learning data. In this case, the method for compensating the estimated cultivation condition by the controller 130 is the same as the method for compensating the preset cultivation condition as described above. Similarly, when it is determined that the growth data of the new crop satisfies the preset threshold, the controller 130 stores the estimated cultivation condition as learning data.

In addition, when the controller 130 receives an input signal for growing conditions of a new crop from the user, the controller 130 compares the received input signal with the growing conditions of the new crop estimated by the controller 130 and displays the comparison result to the user. . The multi-stage grower 100 according to the embodiment of the present invention may use the user's setting data in a predetermined growing condition. In this case, when a new crop is transplanted, the user can also set a growing condition for the new crop. However, the user's setting data may not be accurate data in the plant factory, and the controller 130 is a crop that is cultivated based on the input signal and the cultivation conditions estimated from the controller 130 to provide the user with a criterion for this. Infer each of the growth data and display the result to the user.

Thereafter, the controller 130 generates a control command for controlling a growing environment of a new crop based on one of an input signal and an estimated growing condition according to a user's selection. That is, the user can select a new crop cultivation condition based on a comparison result of the input signal and the cultivation condition estimated from the controller 130, and the controller 130 selects a cultivation environment of the plant factory based on the selected cultivation condition.
