Description

Electronic device that controls a smart farm that grows shiitake mushrooms {ELECTRONIC DEVICE CONFIGURED TO CONTROL SMART FARM THAT GROWS SHIITAKE MUSHROOMS}

The present invention relates to an electronic device that controls a smart farm that cultivates shiitake mushrooms, and more specifically, to an electronic device that controls a smart farm that improves the cultivation efficiency and quality of shiitake mushrooms.

Shiitake mushrooms belong to the genus Shiitake of the pine family and have long been treated as major edible mushrooms along with pine mushrooms and neungi mushrooms due to their excellent taste, aroma, and texture.

In nature, shiitake mushrooms grow on dead trees or branches of broad-leaved trees such as oaks and chestnuts from spring to fall. Until recently, the method of cultivation was widespread by drilling holes in oak trees and injecting spawn to supply sufficient moisture. It is being done.

However, shiitake mushroom cultivation using logs is rapidly declining due to depletion of oak logs and labor shortage. Recently, the base of the culture medium cultivation method, which involves cultivating by stacking a medium injected with spawn into a base material such as sawdust on a multi-layer shelf in a cultivation facility such as a house, is expanding.

As an example of the technology behind the present invention, Republic of Korea Publication Publication No. 10-1852987 (announced on April 27, 2018) provides information on the mushroom growth environment (temperature, light, humidity, carbon dioxide, wind volume, etc.) within the cultivation facility. Based on this collection, we are launching an integrated growth environment management service that can artificially control the growth environment to plan and produce mushrooms.

For example, even with the above-described shiitake mushroom cultivation method, precise temperature, humidity, and carbon dioxide control are required for the production of white mushrooms with high commercial value, so there are limitations for general cultivation farms.

The present invention was developed to solve the above-mentioned problems, and the purpose of the present invention is to provide a method to increase the efficiency of the shiitake mushroom cultivation process and improve the marketability of shiitake mushrooms.

An electronic device that controls a smart farm for cultivating shiitake mushrooms according to various embodiments of the present invention is based on images taken of a storage unit, a camera unit, and one side of a plurality of media on which the shiitake mushrooms are grown, and the plurality of media. The degree of browning of the one side is determined, and if the determined degree of browning is greater than or equal to a predefined value, the water supply unit is controlled to spray water at 10°C to 20°C onto the plurality of media, and the water is supplied to the It may include a processor that performs an electric shock on the plurality of media when a predefined time required for the media to be soaked in the media elapses. Here, the plurality of media may be accommodated in a media container in which a plurality of holes are arranged and made of an opaque material.

According to various embodiments of the present invention, the present invention can provide a method of increasing the efficiency of the shiitake mushroom cultivation process and increasing the marketability of shiitake mushrooms.

Hereinafter, the operating principle of a preferred embodiment of the present invention will be described in detail with reference to the attached drawings. Additionally, when describing embodiments of the invention, if it is determined that a detailed description of a related known function or configuration may obscure the gist of the present disclosure, the detailed description will be omitted. The terms used below are defined in consideration of the functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, the definitions of terms used should be interpreted based on the content and corresponding functions throughout this specification.

Figure 1 shows the form of a medium according to an embodiment of the present invention.

The medium according to one embodiment of the present invention is a culture medium provided with sufficient nutrients necessary for the growth of shiitake mushrooms and adjusted to an appropriate osmotic pressure and pH. Media can be divided into liquid media and solid media depending on the form, and in one embodiment of the present invention, solid media can be used.

For example, the existing rod-shaped badge used solid wood such as oak. This rod-shaped medium required a lot of labor to cultivate because the location and time of occurrence of shiitake mushrooms were random, and it was difficult to expect consistent quality.

A smart farm badge (which can be defined as a badge, multiple badges, multiple smart farm badges, etc.) according to an embodiment of the present invention can complement the weaknesses of existing rod-shaped badges.

For example, a smart farm medium can be formed from 100g to 300g of sawdust. In this case, the smart farm medium can be formed from a combination of various raw materials such as oak sawdust, rice bran, grain grinds, cotton pods, cottonseed husk, calcium carbonate, gypsum powder, sugar, germanium, and selenium. Smart farm media can maintain a constant humidity by mixing appropriate moisture.

Figure 2 shows a media container according to an embodiment of the present invention.

The above-described smart farm badge can be accommodated in the badge container 10.

Referring to Figure 2, the discharge container 10 may include a main body portion 11, a cover portion 12, and a paper member 13.

The main body 11 can accommodate a smart farm badge.

The main body 11 may be made of various materials such as plastic and wood. For example, the main body 11 may be made of a metal material. According to an embodiment of the present invention, the occurrence of shiitake mushrooms can be triggered by performing an electric shock at the time of shiitake mushroom development. In this case, in order to evenly spread the electric shock across the entire surface of the smart farm medium, the main body 11 is made of metal. It can be formed from any material.

The main body 11 is formed so that the upper side is open. The media container 10 may also be used without the cover portion 12, which will be described later.

The main body 11 is made of an opaque material and can block external light to a predefined level. Through this, the growth of shiitake mushrooms in the part of the smart farm medium surrounded by the main body 11 can be suppressed.

The main body 11 may have a plurality of holes arranged therein. Through this, it is possible to prevent external light from being irradiated into the inside of the smart farm medium while maintaining breathability and breathability.

Additionally, the main body portion 11 can maintain the shape of the Hanji member 13, which will be described later.

The cover part 12 may cover the top of the main body 11. At least a portion of the cover portion 12, for example, the central portion of the cover portion 12, may be open. Through this, one side of the smart farm badge can be exposed in the upward direction.

Alternatively, a filter having breathability and moisture permeability, for example, a filter made of Korean paper, may be placed in the center of the cover portion 12. Even if the cover part 12 on which the filter is placed is placed at the top of the main body part 11, the growth state of shiitake mushrooms can be observed by the position of the filter, and shiitake mushrooms can grow while opening the filter, so the medium for smart farm may be defined as one side exposed in the upward direction. In this case, the filter may be coupled to the cover portion 12 to be detachable.

The Hanji member 13 can be placed between the smart farm medium and the medium container 10. Here, the cold paper member 13 may have breathability and moisture permeability. The Hanji member can accommodate the smart farm medium while providing breathability and breathability to the smart farm medium.

Here, the Hanji member 13 may be formed with a plurality of holes to transmit current to the smart farm medium.

The above-described main body 11 and paper member 13 may be used individually or simultaneously.

Inside the above-described badge container 10 or inside the main body 11, at least one metal line connected to the badge container 10 or the main body 11 is disposed to transmit an electric shock to the inside of the smart farm badge. It can be. The electric shock can be delivered evenly to the entire inside of the smart farm badge through the metal line. The metal line may be in a mesh form.

Referring to FIG. 3, the electronic device 300 that controls a smart farm growing shiitake mushrooms may include a storage unit 310, a camera unit 320, and a processor 330.

The storage unit 310 may include volatile or non-volatile recording media.

The storage unit 310 is connected to one or more processors and can store codes that, when executed by the processor 320, cause the processor 320 to control the electronic device 300.

Here, the storage unit 310 may include magnetic storage media or flash storage media, but the scope of the present invention is not limited thereto. This storage unit 310 may include internal memory and/or external memory, volatile memory such as DRAM, SRAM, or SDRAM, one time programmable ROM (OTPROM), PROM, EPROM, EEPROM, mask ROM, and flash ROM. , non-volatile memory such as NAND flash memory, or NOR flash memory, SSD. It may include a flash drive such as a compact flash (CF) card, SD card, Micro-SD card, Mini-SD card, or memory stick, or a storage device such as an HDD.

As an example, the storage unit 310 may store various information for controlling the growth environment of shiitake mushrooms. For example, the storage unit 310 may store appropriate values for environmental factors such as temperature, humidity, carbon dioxide concentration, and illuminance according to the growth stage of shiitake mushrooms.

The camera unit 320 may include a camera sensor that converts a captured optical signal into an electrical signal, and a signal processing unit that converts an analog image signal captured by the camera sensor into digital data.

Here, it is assumed that the camera sensor is a CCD (Charge Coupled Device) sensor, and the signal processing unit can be implemented with a DSP (Digital Signal Processor: DSP). Additionally, the camera sensor and signal processing unit can be implemented as an integrated unit, or they can also be implemented separately.

As an example, the camera unit 320 can film the growth process of shiitake mushrooms. For example, the camera unit 320 may photograph the cap portion of a shiitake mushroom in real time or periodically and transmit it to the storage unit 310 or a processor 320 to be described later.

The processor 330 can generally control the electronic device 300.

As an example, the processor 330 can control the development period of shiitake mushrooms.

Specifically, the processor 330 can determine the degree of browning of the smart farm medium based on an image taken of one side of the smart farm medium where shiitake mushrooms are grown (spores are inserted). Here, the degree of browning can be defined as the degree to which it turns brown. For example, the processor 330 may determine the degree of browning of one side of the smart farm badge to be 0% to 100%.

If the determined degree of browning is greater than or equal to a predefined value, the processor 330 may control the water supply unit to spray water at a level lower than room temperature onto the smart farm medium. The occurrence of shiitake mushrooms can be triggered when a temperature shock is applied to the smart farm medium through cold water at a certain temperature.

As an example, water below room temperature can be defined as water at about 10°C to 20°C.

Additionally, the processor 330 may perform an electric shock on the smart farm medium to trigger the generation of shiitake mushrooms.

Specifically, the processor 330 may perform an electric shock on the smart farm medium when the predefined time required for water to wet the medium elapses.

In this case, the smart farm medium may include at least one electrode for electric shock. Alternatively, the at least one electrode described above may be disposed in the medium container 10 described above. Alternatively, the at least one electrode described above may be arranged to connect the smart farm medium and the medium container 10.

In one embodiment of the present invention described above, the electric shock may be performed at a voltage of 1 kV to 10 kV for a predefined time.

The temperature shock and electric shock described above may be performed simultaneously or sequentially, and may be repeated multiple times at predefined time intervals.

The processor 330 can determine the harvest time of shiitake mushrooms.

Referring to FIG. 4, the processor 330 may receive an image of a shiitake mushroom cap (hereinafter referred to as a shiitake mushroom image) from the camera unit 320. Figure 4 is an image of the cap of Baekhwago, and the following shiitake mushrooms are assumed to be Baekhwago varieties, but will not be limited thereto.

The processor 330 may distinguish individual shiitake mushrooms based on the shiitake mushroom image 40. For example, a processor can use a deep learning model to distinguish between individual shiitake mushrooms.

In addition, the processor 330 may determine whether the growth stage or harvest time for individual classified shiitake mushrooms has been reached.

According to an embodiment of the present invention, the processor 330 can find various relationships and patterns for crop images from image data collected using various deep learning models.

As an example, the processor 330 may utilize a Region-based Convolutional Neural Network (R-CNN) model or You Only Look Once (YOLO) among the latest deep learning models designed with various depths and structures.

First, the R-CNN series calculates the candidate region of the bounding box surrounding the target object of the input image through a separate candidate region generator (region proposal generator) and passes the result to the next classifier for object classification. It follows a two-stage detector structure that performs bounding box regression.

In one embodiment of the present invention, the processor 330 utilizes Faster R-CNN among several models that follow the above-described structure, resulting in high mean average precision (mAP) and fast processing speed of up to 5 FPS. .

As another example, when using the YOLO (You Only Look Once) system, the processor 330 is a single stage detector and estimates the bounding box class from pixel-level raw data input of the input image. Classification can be solved using a single CNN (Convolutional Neural Network) stream.

In one embodiment of the present invention, among existing single-stage detectors, a YOLO-type single stage detector that exhibits a fast search speed and a high level of mAP is designed to enable real-time stream classification without bottlenecks. there is.

According to one embodiment of the present invention, the processor 330 may perform learning corresponding to the number of individual viewpoints. For example, when shiitake mushroom images are acquired and input from three viewpoints, the processor 330 determines the shape (or section) of individual shiitake mushrooms for each viewpoint, integrates the results, and includes them in the shiitake mushroom image. You can determine the harvest time for individual shiitake mushrooms.

As an example, the processor 330 may receive images taken at at least one viewpoint for at least one shiitake mushroom at predefined time intervals. The processor 330 may distinguish the image into an area of interest and an area of no interest.

Additionally, the processor 330 may identify the growth stage of shiitake mushrooms included in the region of interest based on a learning data set for a plurality of pre-stored shiitake mushroom images (big data).

Additionally, the processor 330 may obtain a first feature map using the first convolutional neuron network in the received image. In this case, the processor 330 may distinguish the region of interest using a region proposal network in the first feature map. Additionally, the processor 330 may update the learning data set by receiving user feedback regarding at least one shiitake mushroom included in the received image.

As an example, the processor 330 may configure a feature map based on the ratio of the area of the ribs 411 formed in the cap to the area of the cap 41 of at least one of the plurality of shiitake mushrooms grown in a smart farm medium. For example, the processor 330 constructs a feature map (first feature map to 2n feature map) according to the ratio of the area of the valley 411 formed in the cap 41 to the area of the cap 41 to determine the size of the shiitake mushroom. You can learn about harvest time or growth stages.

Here, when the ratio of the area of the ribs 411 formed in the hat to the area of the hat 41 is more than a predefined value, the processor 330 selects at least one of the at least one shiitake mushroom corresponding to the hat 41. It can be judged that harvest time has been reached.

As another example, the processor 330 may configure a feature map according to the degree of whitening of at least one cap 41 among a plurality of shiitake mushrooms grown in a smart farm medium. For example, the processor 330 may construct a feature map (first feature map to 2n feature map) according to the degree of whitening of the cap 41 and learn about the harvest time or growth stage of shiitake mushrooms.

Here, when the degree of whitening of the cap 41 is greater than or equal to a predefined value, the processor 330 may determine that at least one of the plurality of shiitake mushrooms corresponding to the cap 41 has reached the harvest time.

Here, the degree of whitening refers to the degree to which the shade appears white, and can be expressed as a value of 0 to 1, for example.

In addition, in one embodiment of the present invention described above, the processor 330 determines that the ratio of the area of the valley formed in the shade 41 to the area of the shade 41 is more than a predefined value, and the whitening of the shade 41 is performed. If the degree is greater than or equal to a predefined value, it may be determined that at least one of the plurality of shiitake mushrooms corresponding to the cap 41 has reached the harvest time.

In addition, in one embodiment of the present invention described above, the processor 330 determines that the ratio of the area of the valley formed in the shade 41 to the area of the shade 41 is greater than or equal to a predefined value, and the whitening degree of the shade is predetermined. If it is greater than the specified value, an alarm can be issued for the number corresponding to the smart farm medium on which at least one of the plurality of shiitake mushrooms is grown. In this case, the processor 3330 may output a phrase instructing to harvest shiitake mushrooms along with an alarm.

For example, assuming that a plurality of shiitake mushrooms are grown in a plurality of smart farm media, the processor 330 can number each of the plurality of smart farm media in advance. Here, by alarming the number corresponding to the medium containing shiitake mushrooms that satisfy the above-mentioned conditions, information to harvest the corresponding shiitake mushrooms that have reached the harvest time can be delivered to the user.

Meanwhile, in one embodiment of the present invention described above, the processor 330 applies a sliding window to the first feature map, classifies the presence or absence of an object included in the sliding window, and determines the location of the sliding window. can do.

Additionally, the processor 330 may obtain a second feature map for the region of interest using a second convolutional neural network, and determine the growth stage of shiitake mushrooms included in the region of interest based on the second feature map.

Additionally, the processor 330 may apply at least one of max pooling, mean pooling, and minimum pooling to the first feature map or the second feature map of the region of interest.

Figure 5 shows the power connection of a smart farm badge according to an embodiment of the present invention.

Referring to Figure 5, a plurality of smart farm badges can form a circuit. For example, multiple smart farm badges can be connected to a power source in parallel. In this case, the same voltage is applied to a plurality of smart farm badges when power is applied, so the same electric shock can be applied at the same time. Through this, the occurrence of shiitake mushrooms can be triggered simultaneously in multiple smart farm media.
