Description

ICT control for fruit farms: Open-field smart farm equipment for preventing cold damage and increasing growth The present invention relates to an open-field smart farm device for preventing cold damage and increasing growth in fruit farms, which can simultaneously provide two functions: operating as a hot water system during low-temperature periods and operating as a cold water system during high-temperature periods. Every year, fruit trees suffer damage from frost damage to flowers in the spring, and in the summer, they suffer heat damage from high temperatures and damage from various pests and diseases. Methods to prevent frost damage in the spring include combustion, blowing, and sprinkling. The combustion method requires lighting a fire under the fruit tree, so there is a high risk of fire when the wind blows; the blowing method is not economically viable due to excessive costs; and the sprinkler method cannot be used despite being economically viable because if the water temperature drops below 2°C when using water from an underground well at 15°C, greater damage occurs. However, although the heating and cooling water spraying method is widely used as it is evaluated as the most economical and safest, it has the disadvantage of being a conventional method that limits its use because the spraying time coincides with the period when night temperatures drop, preventing users from sleeping in the early morning and requiring them to heat water using wood heaters and store it in PE tanks. In addition, during the hot summer season, the barrier against hot sunlight exceeding 30°C becomes reduced, exposing the trees to an environment where they can be damaged by various pests and diseases, which sometimes leads to the death of fruit trees. In order to reduce pests and diseases during such high-temperature periods, the cooling system of the existing cold damage prevention system can be operated to lower the temperature and supply water between 15°C and 25°C to maintain and promote the growth and development of fruit farms. FIG. 1 is a drawing illustrating an open-field smart farm device for preventing cold damage and increasing growth in fruit farms using ICT control according to one embodiment of the present invention. FIGS. 2 and FIGS. 3 are drawings illustrating a method for supplying cooling and heating water to prevent cold damage to fruit farms according to an embodiment of the present invention. Hereinafter, preferred embodiments are described in detail with reference to the attached drawings so that those skilled in the art can easily practice the present invention. However, in describing the preferred embodiments of the present invention in detail, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the present invention, such detailed description is omitted. Additionally, the same reference numerals are used throughout the drawings for parts having similar functions and operations. Additionally, throughout the specification, when a part is described as being 'connected' to another part, this includes not only cases where they are 'directly connected,' but also cases where they are 'indirectly connected' with other elements in between. Furthermore, the description of a component as 'including' means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. FIG. 1 is a drawing illustrating an open-field smart farm device for preventing cold damage and increasing growth in fruit farms using ICT control according to one embodiment of the present invention. Referring to FIG. 1, the device (110) of the present invention includes a water tank (110), a heater (120), a high-temperature water tank (130), a cooler (140), a heating and cooling water tank (150), a heating and cooling water supply device (160), a heating and cooling water spray device (170), a sensing device (180), and a control device (190), etc. The water tank (110) stores water such as well water, groundwater, and tap water. The heater (120) heats water supplied from the water tank (110) using gas, oil, electricity, etc. as an energy source to produce high-temperature water of about 70° to 80°, and the high-temperature water tank (130) stores the high-temperature water heated by the heater (120). The cooler (140) cools the water supplied from the tank (110) to produce cold water of about 10° to 20°. The cooling and heating water tank (150) mixes the cold water and hot water supplied to it to generate and store cooling and heating water having a preset target temperature (e.g., 30° to 40°). At this time, the hot water tank (130) and the cooling and heating water tank (150) are made of a material with an insulating function or have an insulating material coated in the internal space so that the current temperature of the hot water and cooling and heating water can be maintained for a long time.
