Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims the priority benefit of Korean Patent Application No. 10-2019-0171765 filed in the Republic of Korea on Dec. 20, 2019, the disclosure of which is incorporated herein by reference in its entirety. 
     BACKGROUND 
     Field of the Invention 
     The present disclosure relates to a smart farm platform and an operation method thereof, and more particularly to a smart farm platform capable of interconnecting a producer who grows agricultural products using a plant grower and a consumer and an operation method thereof. 
     Discussion of the Related Art 
     Modern people who are greatly concerned about healthy food have felt mental satisfaction in direct cultivation of a vegetable garden and harvesting. As a result, a plant grower for home use capable of growing plants for self-sufficiency, such as vegetables, or decorative plants has been developed. 
     In addition, the number of producers who wish to sell surplus agricultural products, among agricultural products produced using plant growers, and consumers who wish to directly confirm and purchase small-scale organic agricultural products has increased. 
     Efforts to optimize production and consumption of agricultural products in local units to thus reduce generation of food waste while supplying good ingredients in a timely manner have also increased. 
     Meanwhile, innovations using information and communication technology (ICT) have been attempted in agriculture. Research on a smart farm, which is an intelligent agricultural system based on information and communication technology in production, processing, and distribution of agricultural products, has been increasingly conducted. 
     Korean Patent Application Publication No. 10-2019-011121 discloses an online agricultural product wholesale auction platform and a transaction method using the same, where interconnection between a purchaser and a seller, sales, payment, and delivery are supported. 
     Korean Registered Patent Publication No. 10-1723173 discloses an ICT-based agricultural product management and production system, wherein information about a raw material supplier, an agricultural product producer, an infrastructure operator, and a distribution manager are collected to supply cultivars of agricultural products, production timing of the agricultural products, and management information of the agricultural products and to share distribution information of the agricultural products. 
     However, these technologies are provided for professional agricultural companies, associations, and merchants, and it is still difficult for small-scale producers to utilize the technologies. In addition, these technologies collect crop information of plants using agricultural products and plant growers, but they do not recommend or automatically determine prices of the agricultural products (i.e., crops or plants) based on the collected information. It is difficult to predict the harvest timing of agricultural products, and the amount of agricultural products that are harvested, as the amount of supply of agricultural products frequently increases and decreases. Consequently, it is not easy to decide prices of agricultural products. 
     SUMMARY 
     An object of the present disclosure is to provide a smart farm platform capable of interconnecting a producer who grows agricultural products and a consumer and an operation method thereof. 
     Another object of the present disclosure is to provide a smart farm platform capable of automatically recommending or deciding agricultural product information using information collected by a plant grower and an operation method thereof. 
     Another object of the present disclosure is to provide a smart farm platform capable of variously using information collected by a plant grower and an operation method thereof. 
     A further object of the present disclosure is to provide a smart farm platform capable of minimizing generation of agricultural product waste and food waste and an operation method thereof. 
     In accordance with the present disclosure, the above and other objects can be accomplished by the provision of a smart farm platform including a plant grower configured to produce agricultural products, a business platform configured to receive information about the agricultural products and the plant grower from the plant grower, and a terminal connected to the business platform, the terminal being configured to request predetermined information related to the agricultural products and to display a screen based on a reply received from the business platform in response to the request through a display, wherein the business platform decides recommended selling prices of the agricultural products based on state information of the agricultural products and operation history information of the plant grower, among the information received from the plant grower, and the terminal displays the recommended selling prices of the agricultural products through the display.

     The business platform may predict growth states of the agricultural products based on image data of the agricultural products received from the plant grower. 
     In the case in which the agricultural products are agricultural products before harvesting, the business platform may predict harvest timing of the agricultural products based on the predicted growth state and may vary timing when a purchase request for the agricultural products is possible based on the predicted harvest timing. 
     The business platform may predict the maximum amount of production of the agricultural products and the minimum amount of production of the agricultural products based on the predicted growth state and may provide information about the predicted maximum amount of production and the predicted minimum amount of production to the terminal. 
     The business platform may provide recipe information using the agricultural products based on the predicted growth state. 
     The business platform may recommend a predetermined cultivar based on at least one of location information of the plant grower, operation history information of the plant grower, and demand information of agricultural products. 
     The business platform may recommend the predetermined cultivar based on specific cultivar growth information and specific cultivar demand information in a local area from the plant grower. 
     Upon receiving a final input of the recommended selling prices through a producer-side terminal of a producer who uses the plant grower, the business platform may register prices corresponding to the final input as selling prices of the agricultural products. 
     In the case in which the terminal is a consumer-side terminal of a consumer who purchases the agricultural products, the recommended selling prices may be the selling prices of the agricultural products. 
     The terminal may be a producer-side terminal of a producer who uses the plant grower or a consumer-side terminal of a consumer who purchases the agricultural products.

Alternatively, the plant grower  1  may transmit various kinds of information to the business platform  3  in the case in which predetermined conditions are satisfied. 
     The plant grower  1  may transmit state information of agricultural products that are being grown and operation history information of the plant grower  1  to the business platform  3 . 
     For example, the plant grower  1  may transmit the kind, number, disposition, and other growth information of agricultural products that are being grown to the business platform  3 . 
     In addition, the plant grower  1  may acquire images of agricultural products that are being grown and transmit image data to the business platform  3 . 
     In addition, the plant grower  1  may transmit information about the amounts of water and electricity that were used by the plant grower  1 , information about the amount of fertilizer that was introduced into plant grower  1 , and sensing data sensed by various kinds of sensors to the business platform  3 . 
     In addition, the plant grower  1  may transmit information about when and how many times a producer used a specific function of the plant grower  1  to the business platform  3 . 
     Meanwhile, the business platform  3  may decide recommended selling prices of the agricultural products based on the state information of the agricultural products and the operation history information of the plant grower  1 , among the information received from the plant grower  1 . 
     The business platform  3  may transmit information about the recommended selling prices of the agricultural products to the terminal  1   a ,  1   b ,  1   c ,  2   a ,  2   b , or  2   c . The terminal  1   a ,  1   b ,  1   c ,  2   a ,  2   b , or  2   c  may display the recommended selling prices of the agricultural products through the display. 
     According to the embodiment of the present disclosure, it is possible for a producer who farms on a small scale to share farm crops with neighbors and to sell the surplus farm crops in order to make a profit using the plant grower  1 . 
     Since agricultural product waste and food waste cause various social and environmental problems, a solution to minimize generation of waste is needed. 
     The smart farm platform  600  according to the embodiment of the present disclosure is capable of collecting information using the plant grower and recommending or automatically deciding prices based on the collected information. 
     According to the embodiment of the present disclosure, prices of agricultural products of producers to be sold are automatically appropriately recommended or decided, whereby it is possible to further activate use of the smart farm platform  600  and consumption of the agricultural products of producers and to minimize waster of residual agricultural products. 
     Depending on embodiments, the business platform  3  may decide the recommended selling prices based on production costs input through the producer-side terminal  1   a ,  1   b , or  1   c  of the producer who uses the plant grower  1 . That is, at the time of price calculation, the business platform  3  may decide the recommended selling prices based on costs that the producer Producer 1 , Producer 2 , or Producer 3  directly input through the producer-side terminal  1   a ,  1   b , or  1   c.    
     Alternatively, the business platform  3  may decide the recommended selling prices based on production costs calculated based on the operation history information of the plant grower  1 . That is, at the time of price calculation, the business platform  3  may automatically decide the recommended selling prices based on the operation history information of the plant grower  1  without input of the producer Producer 1 , Producer 2 , or Producer 3 . For example, the business platform  3  may calculate production costs based on the amounts of water and electricity that were used by the plant grower  1  and the amount of fertilizer that was introduced into the plant grower  1 , and may decide the recommended selling prices based on the calculated production costs. 
     The business platform  3  may calculate the production costs based on information about at least one of the amounts of water, electricity, and supplies that were used by the plant grower  1 . In addition, the business platform  3  may calculate the production costs in overall consideration of water, fertilizer, electricity, and supplies that were used by the plant grower  1 . 
     Meanwhile, the business platform  3  may include personnel expenses calculated based on the manipulation history information of the plant grower  1  and sensing data of the plant grower  1  in the production costs. For example, the business platform  3  may calculate work time of the producer Producer 1 , Producer 2 , or Producer 3  based on the manipulation history of a main body of the plant grower  1  and sensing data acquired by a human body sensor included in the plant grower  1 , and may calculate personnel expenses based on the calculated work time. 
     Consequently, the business platform  3  according to the embodiment of the present disclosure is capable of reflecting personnel expenses in prices, whereby it is possible to more appropriately set prices. 
     Meanwhile, the business platform  3  may evaluate the states of the agricultural products based on the image data of the agricultural products received from the plant grower  1 , and may provide information about the states of the agricultural products to the terminal  1   a ,  1   b ,  1   c ,  2   a ,  2   b , or  2   c.    
     That is, the business platform  3  may evaluate the states of the agricultural products based on the image data of the agricultural products received from the plant grower  1 , and the terminal  1   a ,  1   b ,  1   c ,  2   a ,  2   b , or  2   c  may display the result of evaluation. 
     Consequently, it is possible for both the producer Producer 1 , Producer 2 , or Producer 3  and the consumer Demand 1 , Demand 2 , or Demand 3  to directly view the current images of the agricultural products and to confirm image-based evaluation data. 
     Meanwhile, the business platform  3  may decide the recommended selling prices based on the result of image-based evaluation and the calculated production costs. For example, the business platform  3  may suggest prices different in grades by grading the agricultural products based on images and reflecting grades of the agricultural products in the production costs. 
     Meanwhile, the business platform  3  may decide the recommended selling prices based on the amount of production of the agricultural products collected from the producer-side terminals  1   a ,  1   b , and  1   c  and the level of demand for the agricultural products collected from the consumer-side terminals  2   a ,  2   b , and  2   c.    
     That is, the business platform  3  may primarily decide prices in terms of cost, and may recommend adjusted prices in consideration of the level of demand. 
     The business platform  3  may receive information from the plant growers  1  of the plurality of producers Producer 1 , Producer 2 , and Producer 3 , and may analyze the received information. Consequently, it is possible to know the kind and the harvest timing of agricultural products to be produced by the plant growers  1 , whereby it is possible to estimate the amount of supply of specific agricultural products. Depending on embodiments, the business platform  3  may acquire amount-of-supply information from the outside over a wired/wireless network. 
     Meanwhile, upon receiving the final input of the recommended selling prices through the producer-side terminal  1   a ,  1   b , or  1   c  of the producer who uses the plant grower  1 , the business platform  3  may register the prices corresponding to the final input as selling prices of the agricultural products. 
     Meanwhile, in the case in which the terminal  1   a ,  1   b ,  1   c ,  2   a ,  2   b , or  2   c  is the consumer-side terminal  2   a ,  2   b , or  2   c  of the consumer who purchases the agricultural products, the displayed recommended selling prices may be the selling prices of the agricultural products. 
     Depending on embodiments, the seller may set the recommended selling prices suggested by the business platform  3  as the minimum prices. In this case, the final prices may be decided by reflecting the amount of production and the level of demand in a price range equal to or higher than the recommended selling prices. Upon determining that it is difficult to select prices equal to or higher than the minimum prices, the business platform  3  may transmit an alarm signal to the producer-side terminal  1   a ,  1   b , or  1   c.    
     Meanwhile, the business platform  3  may decide the recommended selling prices based on the amount of production of the agricultural products collected from the producer-side terminals in a local area and the level of demand for the agricultural products collected from the consumer-side terminals in the local area. 
     Depending on embodiments, the business platform  3  may interconnect a producer and a consumer within a local area. As a result, agricultural products produced in a local area may be consumed and delivered only in the local area, whereby it is possible to maximally prevent generation of agricultural product waste, to reduce necessity for storing the agricultural products, and to reduce the amount of carbon dioxide and expenses generated during delivery. 
     Meanwhile, upon receiving a purchase request for a specific agricultural product from the consumer-side terminal  2   a ,  2   b , or  2   c , the business platform  3  may provide information about a delivery path from a seller of the specific agricultural product to a consumer who purchases the agricultural product to the consumer-side terminal  2   a ,  2   b , or  2   c . As a result, the consumer may confirm expected delivery time and path. 
     Meanwhile, the business platform  3  may predict the growth states of the agricultural products based on image data of the agricultural products received from the plant grower  1 . 
     Based on image data of the agricultural products received from the plant grower  1 , the business platform  3  may determine the current states of the agricultural products and may predict the harvest timing, the amount of production, and grades of the agricultural products. 
     It is difficult for an inexperienced producer to predict the growth states of agricultural products that are being grown. According to the embodiment of the present disclosure, however, it is possible for even an inexperienced producer to confirm information about the predicted growth states of the agricultural products to thus make a growth plan. 
     Meanwhile, the business platform  3  may predict the maximum amount of production of the agricultural products and the minimum amount of production of the agricultural products based on the predicted growth state, and may provide information about the predicted maximum amount of production and the predicted minimum amount of production to the terminal  1   a ,  1   b ,  1   c ,  2   a ,  2   b , or  2   c.    
     In the case of individual growth, a large amount of agricultural products may become waste if production variation is great and the amount of production is excessively increased. According to the embodiment of the present disclosure, however, it is possible for even an inexperienced producer to confirm information about the predicted growth states of the agricultural products and to systematically grow the agricultural products or to induce consumption of surplus agricultural products through low price setting, whereby it is possible to minimize generation of waste. 
     Meanwhile, in the case in which the agricultural products are agricultural products before harvesting, the business platform  3  may predict the harvest timing of the agricultural products based on the predicted growth state, and may vary timing when a purchase request for the agricultural products is possible based on the predicted harvest timing. 
     That is, in the case in which purchase of agricultural products that have not yet been harvested is offered, timing when offer for purchase is possible may be adjusted based on the predicted harvest timing, which may assist a consumer in confirming data related to the agricultural products at desired timing and deciding purchase and which may assist a producer in performing sale-related activities only at specific timing or establishing a growth plan. 
     Meanwhile, the business platform  3  may provide recipe information using the agricultural products based on the predicted growth state. In particular, the business platform  3  may widely announce recipe information using agricultural products expected to be excessively produced in order to increase consumption of excessively produced agricultural products, whereby it is possible to minimize generation of waste. 
     Meanwhile, the business platform  3  may recommend a predetermined cultivar based on at least one of location information of the plant grower  1 , operation history information of the plant grower  1 , and demand information of agricultural products. As a result, it is possible for producers to establish growth plans based on supply and/or demand prediction. 
     In addition, the business platform  3  may recommend the predetermined cultivar based on specific cultivar growth information and specific cultivar demand information in a local area from the plant grower  1 , whereby it is possible to establish a growth plan in consideration of a growth plan in an area in the vicinity of the plant grower  1 . In addition, the business platform  3  may recommend growth of a specific cultivar to a producer at a place having the smallest delivery distance based on location information of a consumer who frequently buys the specific cultivar. Consequently, the business platform  3  may interconnect a producer and a consumer in a specific area. 
     As described with reference to  FIGS. 1 to 5 , the disposition of the growing panels  30   a ,  30   b ,  30   c ,  30   d ,  30   e , and  30   f  of the plant grower  1  may be varied. 
     The disposition form of the growing panels  30   a ,  30   b ,  30   c ,  30   d ,  30   e , and  30   f  of the plant grower  1  in a day mode and the disposition form of the growing panels  30   a ,  30   b ,  30   c ,  30   d ,  30   e , and  30   f  of the plant grower  1  in a night mode may be different from each other. That is, the plant grower  1  may have the disposition form of  FIG. 1  in the day mode, and may have the disposition form of  FIG. 2  in the night mode. 
     In the night mode, the growing panels  30   a ,  30   b ,  30   c ,  30   d ,  30   e , and  30   f  may be disposed so as to face the interior of the plant grower  1 . At this time, the lighting bar  64  and the camera sensor  74  in the plant grower  1  may be operated. 
     In the day mode, the surfaces of the growing panels at which the growing holders  36  are disposed may be disposed so as to face the exterior of the plant grower  1 . In the day mode, therefore, plants may be exposed to natural light. 
     In the night mode, the surfaces of the growing panels at which the growing holders  36  are disposed may be disposed so as to face the interior of the plant grower  1 . In the night mode, therefore, plants may be exposed to light emitted by the lighting bar  64 . 
     Consequently, the plant grower  1  according to the present disclosure is capable of growing plants day and night using natural light from the sun and light from the lighting bar  64 , whereby it is possible to increase the growth speed of the plants. 
     Also, in the night mode, images of the plants may be captured by the camera sensor  74  in a uniformly bright situation based on light from the lighting bar  64 , whereby it is possible to acquire high-quality images. That is, the lighting bar  64  may project light in a uniform manner towards the plants of the plant grower  1  to allow for the camera to take improved images of the plants. 
     In addition, images are acquired in a uniform environment, which is advantageous in determining the states of plants based on images. 
       FIG. 7  is a schematic inner block diagram of a smart farm platform server according to an embodiment of the present disclosure, which shows an example of a server configured to provide a service of the smart farm platform. 
     Referring to  FIG. 7 , the server  700  may include a communication unit  720  (i.e., communicator), a processor  710  (e.g., CPU, controller), and a memory  730 . 
     The processor  710  may control overall operation of the server  700 . 
     The processor  710  is loaded with an artificial neural network (ANN) trained through machine learning. Consequently, the processor  710  may perform agricultural product recognition, recommenced price calculation, and growth information determination based on images. The artificial neural network (ANN) may be embodied in the form of software or hardware, such as a chip. 
     For example, the processor  710  may include a deep neural network (DNN) trained through deep learning, such as a convolutional neural network (CNN), a recurrent neural network (RNN), or a deep belief network (DBN). 
     Meanwhile, the server  700  may be a server operated by a manufacturer of the plant grower  1 , a server operated by a service provided, or a cloud server. 
     The communication unit  720  may receive various kinds of data, such as state information, operation information, and manipulation information, from the plant grower  1 , the terminal  1   a ,  1   b ,  1   c ,  2   a ,  2   b , or  2   c , a gateway, or another electronic device. 
     The communication unit  720  may transmit data corresponding to the received various kinds of information to the plant grower  1 , the terminal  1   a ,  1   b ,  1   c ,  2   a ,  2   b , or  2   c , the gateway, or the other electronic device. 
     To this end, the communication unit  720  may include at least one communication module, such as an Internet module or a mobile communication module. 
     The memory  730  may store received information, and may have data necessary to generate result information corresponding thereto. 
     In addition, the memory  730  may store data used in machine learning, result data, etc. 
     The memory  730  may store data necessary to operate the server  700 . 
     For example, the memory  730  may store a learning algorithm that is executed by the server  700 . The learning algorithm may be a learning algorithm based on a deep neural network, as shown in  FIG. 8 . 
     Referring to  FIG. 8 , deep learning, which is a kind of machine learning, may perform learning to a deep level in multiple stages based on data. 
     Deep learning may be a set of machine learning algorithms that extract core data from plural data via hidden layers in turn. 
     A deep learning structure may be constituted by a deep neural network (DNN), such as a convolutional neural network (CNN), a recurrent neural network (RNN), or a deep belief network (DBN). 
     The deep neural network (DNN) may include an input layer, a hidden layer, and an output layer. 
     Meanwhile, the deep neural network (DNN) may have multiple hidden layers. 
     Each layer may include a plurality of nodes. Each layer is connected to the next layer. The nodes may have weights and may be connected to each other. 
     An output from an arbitrary node belonging to a first hidden layer becomes an input of at least one node belonging to a second hidden layer. At this time, an input of each node may be a value obtained by applying a weight to the output of the node of the previous layer. The weight may mean intensity of connection between nodes. A deep learning process may be a process of finding an appropriate weight. 
     Meanwhile, the artificial neural network may be trained by adjusting a weight of a connection line between nodes (if necessary, by also adjusting a bias value) such that a desired output is obtained from a given input. In addition, the artificial neural network may continuously update the weight value through training. 
       FIG. 9  is a conceptual view of a smart farm platform according to an embodiment of the present disclosure. 
     Referring to  FIG. 9 , a business platform  3  may provide various kinds of information about and services related to agricultural products and a plant grower  910  in the form of an application (APP)  930 . 
     A producer (or a seller who is entrusted with sales by a producer or who purchases agricultural products from a producer and sells the purchased agricultural products) and a consumer may use a service of the business platform  3  using a consumer-side terminal  940 . 
     The smart farm platform  900  may include a supply partner  950  and a share/sale partner  960 . The supply partner  950  may include culture medium, nutrient, and soil suppliers. The share/sale partner  960  may include grocery stores, restaurants, and individual purchasers. 
     The culture medium, nutrient, and soil purchased from the supply partner  950  are necessary for the plant grower  910  to grow plants. In addition, surplus agricultural products, among agricultural products grown by the plant grower  910 , may be sold to the share/sale partner  960 . 
     Referring to  FIG. 9 , a database  920  of a server  700  included in the business platform  3  may store data related to the application  930  provided by the business platform  3 . 
     For example, the database  920  may store data received from the plant grower  910  and secondary data based on the data received from the plant grower  910 . Here, the secondary data may include production data, recognition data, analysis data, and learning data calculated based on the data received from the plant grower  910 . 
     In addition, the database  920  may also store activity information of the supply partner  950  and the share/sale partner  960 .
