1 and 2 are a flowchart and a system configuration diagram for implementing the smart farm operating method of the present invention.

First, the wireless communication module 101 receives the measurement values of the sensors including the temperature sensor S1, the humidity sensor S2, the dust sensor S3, the CO ₂ detection sensor and the illuminance sensor, and the AD converter 103 is the After converting the measured value into a digital signal, a transmission/reception step (S10) in which a microcontroller unit (MCU) transmits the digital signal to the server 200 through the wireless communication module 101 is performed.

The wireless communication module 101, as a component of the platform 100, collects the measured values measured by the sensors S1, S2, and S3 through a wireless communication network and transmits them to the server 200, and the server 200 ) can receive various control signals. For example, Bluetooth communication is good.

The microcontroller unit 105 refers to a miniature controller in which minimal computing elements such as a processor, a memory, and an input/output bus are built in an integrated circuit, and is a component of a platform.

A system configuration diagram will be described in more detail.

The wireless communication module receives measurement values of sensors including a temperature sensor (S1), a humidity sensor (S2), a dust sensor (S3), a CO _{2 sensor, and an illuminance sensor.}

The AD converter converts the measured value into a digital signal.

The microcontroller unit 105 transmits the digital signal to the server 200 through the wireless communication module 101 .

The control unit controls various devices including a hot air blower, a cold blower, a humidifier, a dryer, a water supply machine, a ventilator, an LED light, a relay, and a fertilizer feeder.

The server loads the reference value regarding the growth condition according to the type of crop and the current state such as the presence or absence of disease or pest from the database 400, and outputs the measured value to the screen of the user terminal 300, and the measured value It is determined whether the reference value is satisfied (S40a) and whether the current state is normal (S40b), and if the reference value is not satisfied or the current state is not normal, a push alarm is transmitted, and a control signal from the user terminal 300 is received and transmitted to the control unit 107 .

3, 4 and 5A are perspective views showing the housing 700, the cover 800, and the heat sink 900 among the temperature sensors used in the system for implementing the smart farm operating method of the present invention, respectively.

In the temperature sensor S1 of the present invention, a sliding pin 730 connects two parallel first and second support parts 710 and 720 extending toward the center of the cylinder on the inner circumferential surface of the cylinder, and the A non-conductive cylindrical housing 700 in which a fitting hole 744 is formed on the opposite inner peripheral surface of the first support part 710 and the second support part 720 ; The lower layer is a graphene thin film layer 741 and the upper layer is laminated with a copper thin film layer 742 , one end of which is formed with a sliding hole 731 in the longitudinal direction to insert the sliding pin 730 , and the other end is the fitting hole 744 . ) inserted into the rectangular double layer 740 protruding through the outer circumferential surface of the housing 700; a conductive cover 800 covering the upper opening of the housing 700 and having electrode pins 810 extending vertically downward from the center; and a heat sink 900 covering the lower opening of the housing 700 and having a plurality of heat dissipation fins 910 formed thereon.

In particular, the electrode fin 810 and the copper thin film layer 742 are spaced apart from each other by a predetermined distance, and as the temperature increases, the double layer 740 due to the difference in the expansion rate of the copper thin film layer 742 and the graphene thin film layer 741. This upward bending is characterized in that the copper thin film layer 742 and the electrode pin 810 are in electrical contact.

On the other hand, when the double layer 740 is bent upward by heating, the sliding pin 730 moves back and forth along the sliding hole 731, so that bending is not prevented.

Meanwhile, an auxiliary hole 733 is formed at the other end of the double layer 740 to facilitate soldering of electric wires.

On the other hand, the heat dissipation plate 900 is preferably made of a material with good thermal conductivity, and further includes a heat dissipation fin to facilitate heat generation through the upper double layer 740 .

Figure 5b is a longitudinal cross-sectional view when not heated showing the temperature sensor used in the system for implementing the smart farm operating method of the present invention.

At a normal room temperature of about 25° C., the double layer 740 does not expand and becomes horizontal, so that the electrode pin 810 and the copper thin film layer 742 do not electrically contact each other. Cover 800 is conductive.

Figure 5c is a longitudinal cross-sectional view at the time of heating showing a temperature sensor used in a system for implementing the smart farm operating method of the present invention.

Unlike FIG. 5B , as the temperature increases, the double layer 740 begins to warp upward according to a difference in the expansion rate. This is because the graphene thin film layer 741 contracts as the temperature rises, and the copper thin film layer 742 expands as the temperature rises. Accordingly, the copper thin film layer 742 can be in electrical contact with the electrode pin 810 while being bent.

Figure 5d is a conceptual diagram constituting a closed circuit at the time of heating showing the temperature sensor used in the system for implementing the smart farm operating method of the present invention.

When the copper thin film layer 742 electrically contacts the electrode pin 810 as shown in FIG. 5C , a closed circuit is formed, the current of the power flows, and the ammeter reacts to detect that the copper thin film layer 742 is heated to a certain temperature or more.

Referring again to Figs. 1 and 2, the next step of the present invention will be described.

Next, the server 200 proceeds the loading step (S20) of loading the current state, such as the presence or absence of a disease or pest, and a reference value regarding the growth conditions according to the type of crop from the database 400.

Since the growth conditions are different for each crop, it is stored in advance in the database 400 .

In the case of sunlight, it is classified as a sunny plant, a semi-shade plant, and a shade plant according to the light intensity, so the standard value of the amount of sunlight is different depending on the target crop. Plants that like direct sunlight are pine, zelkova, persimmon, and cycad, and plants that like shade are yew, guaneum porridge, benjamin, rubber tree, and orchid orchid. Also, if we look at the light saturation point of each crop, it is 80Klux for watermelon, 70Klux for tomato, 55Klux for cucumber, 45Klux for pumpkin, 40Klux for Chinese cabbage, 30Klux for bell pepper, and 25Klux for lettuce.

In addition, according to the temperature, it is divided into tropical plants, temperate plants, and cold-tropical plants. For tropical plants, 25-30℃, temperate plants 15-25℃, and cold-tropic plants 10-20℃ are used as standard values.

Also, depending on the humidity, there are aquatic plants, wet plants, metaphysical plants, and dry plants. Furthermore, depending on the nature of the soil, there are cultivated soil, humus soil, masa soil, perlite, peat moss, and the like.

Also, the concentration of carbon dioxide is generally around 1000~1500ppm, and 500~1500ppm of fruits and vegetables, 1500~2000ppm of leafy vegetables, and 1000~3000ppm of root vegetables are appropriate. Do.

In addition, there are nitrogen, phosphoric acid, potassium, etc. depending on the fertilizer, and it is important to grow leaves well for houseplants, so fertilizers with high nitrogen content should be used. On the other hand, an important component for flowering or fruiting is phosphoric acid. In addition, the ingredient that strengthens the roots and stems is potassium.

Furthermore, diseases and pests must be considered, and there are leaf demise, anthrax, soft blight, and powdery mildew. Depending on the disease, the appropriate pesticide should be used. In the case of leaf loss, the leaves turn brown or black due to strong sunlight. In order to avoid direct sunlight, it is necessary to properly shade the sunlight. Anthrax is a disease in which brown spots appear on a part of the leaf and the dead part turns grayish-white, which is caused by high humidity. Prevention is important because it is difficult to control. Soft blight is a disease that appears due to gout, and the lush leaves must be appropriately cut. Powdery mildew is a phenomenon in which flour is sprinkled on the surface of the leaves, and good ventilation is required to remove mold.

In addition, there are mites, mealybugs, leaf moths, and aphids as pests, and appropriate pesticide spraying is required.

Watering times should vary according to the season.

The growth conditions as described above are stored in the database 400 in advance according to the target crop, and as the target crop is selected, it is managed and monitored whether the reference value of the growth condition is met. Furthermore, it is better to store the current state such as the presence or absence of diseases or pests, and to perform a simulation that can respond appropriately by randomly generating events such as disease occurrence or pest occurrence.

Next, the server 200 proceeds with an output step (S30) of outputting the measured value to the screen of the user terminal (300).

The user terminal 300 is a terminal used by a user who wants to manage a virtual farm, and may be a smartphone, a laptop, or the like.

6A and 6B are dashboards output on the screen of the user terminal 300 when implementing the smart farm operating method of the present invention.

The measured values of each sensor are intuitively displayed on the user terminal 300 in the form of a dashboard or a graph for each sensor node.

6c is a diagram illustrating measurement values and push alarms of sensors output on the screen of the user terminal 300 when implementing the smart farm operation method of the present invention.

Next, the server 200 proceeds to a determination step (S40) of determining whether the measured value satisfies the reference value and whether the current state is normal.

As described above, the reference value is different for each target crop. The server 200 determines whether there is a special abnormality when the current state of the crop is loaded at random with the presence or absence of diseases, pests, and the like.

Next, when the reference value is not satisfied or the current state is not normal, the server 200 proceeds with an alarm step (S50) in which a push alarm is transmitted. In the case of a smartphone, a push alarm service is provided, so it is good to notify the user immediately if an abnormality is found. The server 200 of the present invention includes a push alarm server.

Next, the server 200 receives the control signal from the user terminal 300 and transmits it to the control unit 107 so that the control unit 107 is a hot air blower, a cold air machine, a humidifier, a dryer, a water supply machine, a ventilator, an LED light, a relay and a fertilizer. A control step (S60) for controlling various devices including the feeder is performed.

Furthermore, it is also good to proceed with the step (S70) of allowing the user to directly correct the measured values of the sensors.

The user may respond appropriately to the reference value or the current state by touching the screen of the user terminal 300 . That is, when the temperature is low, it is possible to transmit a control signal to operate the hot air fan. When the humidity is low, the humidifier can be operated, when there is a lot of fine dust, the fan can be operated, when the illumination is low, the LED lighting, and when the specific nutrients are low, the fertilizer supply can be operated. It is preferable to control various devices through the control unit 107 of the platform 100 of the present invention via the server 200 through wireless communication. The control unit 107 is a component indicating a device control device such as a motor control chip controlled by the MCU.

According to the present invention, even if the actual farm is not built, it is possible to sufficiently experience and educate the farm operation through the virtual farm, and there is an advantageous effect of cultivating farm operation experts at a low cost by appropriately responding to an emergency situation.

Furthermore, it has an advantageous effect that it can be actively used in smart farms using already established ICT (Information and Communications Technologies), and can induce users to develop them themselves.
