Agriculture is an industry that uses the land to cultivate necessary plants for life and to grow useful crops. In particular, farming often refers to farming by plowing the rice fields, which means growing crops such as rice, barley, wheat, and corn.

In general, crops require a lot of labor and experience in their management because their yield and quality are affected by changes in the external environment such as temperature and humidity. In addition, since it is difficult to share opinions with the relevant experts on how to manage specific crops, etc., the managers tend to rely on experiences of trial and error. That is, there is a problem in that a large amount of labor is required because crop yield is reduced or crop quality is large, and the condition of crops needs to be continuously managed due to wrong habits or wrong judgment of managers and unexpected external environmental changes.

It may be transmitted to the terminal 200. The communication unit 130 may use various wireless communication schemes, for example, various wireless communication schemes such as Zigbee, Bluetooth, and WiFi. In addition, the user terminal 200 or external information such as a sensor measurement value measured by the sensor 110, a state of the arable land determined from the sensor measurement value, or a development state of crops using the Internet of Things (IoT) network may be used. It may be transmitted to the database 300. For reference, the external database 300 may be a database of the Meteorological Agency, a database of a separate drought forecast management company or a database of an agricultural consulting company, but is not necessarily limited thereto.

Here, the communication unit 130 of the smart crop management module 100 according to an embodiment of the present invention is measured by the sensor 110 using a LoRa network (LoRa network; Long Range Wide Area network) of the IoT network It is preferable to transmit information, such as a sensor measurement value, the state of the arable land determined from the sensor measurement value, or the development state of a crop, to the user terminal 200 or the external database 300.

The main power supply unit of the power supply unit 140 is a power supply for always supplying power to the sensor 110, the control unit 120, the communication unit 130, and the like. At this time, the main power supply of the power supply 140 is preferably provided as a secondary battery capable of charging and discharging, the main power supply may be charged by the power of the auxiliary power supply. For example, the control unit 120 may determine the remaining power amount of the main power supply unit. If the remaining power amount of the main power supply unit determined by the control unit 120 is not sufficient to operate the sensor 110 or the like, or reaches a minimum value. If it is determined that the first power supply unit is connected to the main power supply unit can be charged using the power of the auxiliary power supply unit. When the control unit 120 determines that the main power supply unit is charged and reaches a maximum value, the connection of the main power supply unit and the sub power supply unit may be blocked.

If the amount of charging of the auxiliary power unit due to the solar heat does not reach the reference value, the priority of charging by the renewable energy may be set so that the auxiliary power unit is charged using the geothermal heat. Since there is not enough geothermal power generation compared to solar heat, the charging of auxiliary power by solar power is given priority, but geothermal power may be used depending on weather conditions such as cloudy or rainy weather. However, it is preferable to charge the auxiliary power supply using sunlight rather than geothermal heat.

On the other hand, the smart crop management module 100 according to an embodiment of the present invention may be used when a plurality of crops of different types are cultivated in the arable land. For example, as shown in FIG. 3, the smart crop management module 100 installed at predetermined positions S1, S2, and S3 in each arable land in which different crops are cultivated has an acidity, water content, and soil content for each arable land. The measured value of the sensor 110 such as temperature and ground temperature, the current state of each arable land, the growth state of the crop being cultivated in each arable land, etc. may be determined and transmitted to the user terminal 200 or the external database 300.

In addition, in conjunction with the smart crop management module installed by other users who grow the same crops, it provides information on cropland for a certain regional unit (for example, cotton unit, military unit, etc.) or crops suitable for farming. You may.

Meanwhile, the controller 120 according to an embodiment of the present invention may calculate a natural drought index (NDI) from the measured value of the sensor 110. Among natural disasters, drought is a long-lasting and wide-area disaster that can have a significant impact on crop yields. However, it is not easy to predict drought. This is because drought is closely related to the condition of arable land as well as precipitation. For example, drought is related to the amount of natural runoff to groundwater, depending on the amount of arable land, as well as the amount of soil water occupied by the arable land and the permeability of the arable land. Therefore, it is possible to calculate the natural drought index by measuring the soil water content and natural runoff amount of the arable land.

It may be stored in or transmitted to the user terminal 200 or the external database 300 through the communication unit 130. In this case, the external database 300 may include a database of a meteorological office or a drought information management company. The natural drought index is stored in a database of the meteorological office, so that the meteorological office can manage drought in a corresponding region. For example, as a result of analyzing the natural drought index stored in the database of the Meteorological Administration, if drought is expected on the arable land, the user may transmit measures such as expansion of irrigation facilities in advance to the user terminal 200 to prevent drought measures. To establish.

In addition, by analyzing the natural drought index per unit region including the cultivated land can also manage drought in the wide area unit.

As such, since the smart crop management module 100 according to an embodiment of the present invention is embedded in land of arable land, it is possible to constantly measure soil water content and natural discharge of arable land, and thus to calculate natural drought index. There is also the advantage that no separate means for.
