When the current flows into the water spray control unit 147, the electromagnetic force generated in the magnetic unit 147d does not occur. When the electromagnetic force disappears from the magnetic part 147d, the attraction force generated between the magnetic part 147d and the blocking part 147c also disappears. When the attraction force disappears, the elastic portion 147b attached to the inside of the control body 147a is vertically lowered, and the blocking portion 147c attached to the lower end of the elastic portion 147b is lowered to spray the water tank 40 The high pressure air mixed with water is stopped from flowing in, and supply of the high pressure air and water to the sprayer 140 is stopped.

When the supply of high pressure air and water is stopped, the pressure inside the spray unit 140 gradually decreases. When the pressure inside the spray unit 140 decreases, the contracted elastic member 142 starts to relax in the direction of the nozzle 145.

When the elastic member 142 is relaxed, the plate 143 attached to the lower end of the elastic member 142 is also pressed down vertically. When the plate 143 is pushed down vertically, the needle 144, which is vertically fixed on the bottom surface of the plate 143, is also vertically lowered, and the needle 144, which has opened the inlet of the nozzle 145, is vertical. By descending, the inlet of the nozzle 145 is closed, so that water can be sprayed on the crop.

The address allocating unit 121 of the crop management unit 120 allocates the same address information to the cultivation zone 20 and the spray unit installed above the cultivation zone 20.

 The standard information unit 122 may input standard information 60 to address information allocated by the address allocator 121. The information set unit 123 divides the address information input with the standard information 60 into a plurality of sub-information, generates a plurality of files 70 and stores them in a physical space. The file generating unit 123a The address information to which the standard information 60 is input may be divided into a plurality of lower pieces of information, and generated as a plurality of files 70. The random number allocator 123b is composed of one or more, and generates a separate ID to generate the same random number for a predetermined time.

The random number allocator 123b assigns and shares a separate ID to the generated plurality of files 70. Through the above process, the plurality of files 70 share the same random number generated for a predetermined time.

The address assigning unit 123c allocates a plurality of files 70 sharing the same random number to the physical space itself for distributed storage, and the information storage unit 123d stores the plurality of files 70. Store in the physical space to which the address is allocated.

When the environmental information 50 obtained by the environmental measurement unit 110 is transmitted to the crop management unit 120, the temperature control unit 124 included in the crop management unit 120 calls a plurality of stored files 70. In this case, the plurality of files 70 are recombined through the same random number, and the stored standard information 60 is converted into input address information and called.

The called standard information 60 compares the input address information with the environmental information 50 obtained from the environmental measurement unit 110, and analyzes the crops that are included in the input information of the standard information 60. The standard temperature data required and the temperature data of the cultivation zone 20 included in the environmental information 50 may compare the temperature based on a predetermined time unit.

When the temperature data of the cultivation zone 20 is analyzed to be higher than the standard temperature data necessary for the crop to grow, the temperature controller 124 selectively transmits to the sprayer 140 through a facility controller (not shown) based on the address information. The electrical signal may be transmitted and controlled, and the circulation water pumping unit 135 of the cold air supply unit 130 may be controlled.

The circulating water having a cold nature is pumped and moved to the atmospheric endothermic unit 131 through the circulating water inlet tube and the circulating water discharge tube, and the circulated water moved to the atmospheric endothermic unit 131 by the circulating water pumping unit 135. May lower the ambient temperature inside the plastic house 10. The circulating water has a property of absorbing the surrounding heat within a short time, thereby circulating the circulating water continuously to adjust the air temperature inside the vinyl house 10, and the electrical signal of the facility control unit (not shown) is stopped. The circulation water pumping unit 135 may continue to operate until it becomes.

The cold air supply unit 130 located inside the vinyl house 10 and the circulating water tank 30 located outside the vinyl house 10 are connected to each other so that the circulation of the circulating water is between the cold air supply unit 130 and the circulating water tank 30. Since recycling continues, the heat is absorbed from the inside of the vinyl house 10 to continuously lower the internal temperature, thereby preventing crops from quickly losing moisture, thereby enabling smooth crop cultivation.

In addition, referring to FIG. 11, cold air may be supplied to the vinyl house 10 by configuring the cold air converting unit 170 not only on the ground but also over the vinyl house 10. The external circulation unit 160 that receives the coolant from the coolant tank 150 may move the coolant to the cold wind converting unit 170 through the cold water supply unit 161, and the coolant moved to the cold wind converting unit 170 may be cold wind. The cold air discharge unit 171 may blow air inside the vinyl house by absorbing the ambient temperature around the converter 170 and lowering the temperature. Cooling water having a temperature rise in the cold air conversion unit 170 is moved to the hot water discharge unit 162 is discharged to the coolant tank 150 again.

In addition, the temperature controller 124 may transmit and control an electric signal to the water spray controller 147. When a current flows into the water spray control unit 147, an electromagnetic force is generated in the magnetic unit 147d. When an electromagnetic force is generated in the magnetic part 147d, an attractive force is generated between the magnetic part 147d and the blocking part 147c, so that the elastic part 147b attached to the inside of the control body part 147a rises vertically. In addition, the blocking part 147c attached to the lower end of the elastic part 147b is lifted up, and high pressure air mixed with water is introduced from the water spray tank 40 and supplied to the sprayer 140.

Thus, the high pressure air and water supplied from the water spray control unit 147 is introduced through the entrance pipe 146 of the spray body 141.

When the high pressure air is introduced, the pressure inside the spray unit 140 is increased. When the pressure inside the spray unit 140 rises, the elastic member 142 coupled with the spray body unit 141 starts to contract in the direction of the spray body unit 141. When the elastic member 142 shrinks, the plate 143 attached to the lower end of the elastic member 142 also rises vertically. When the plate 143 rises vertically, the needle 144 standing up and fixed to the bottom surface of the plate 143 also rises vertically, and the needle 144 blocking the inlet of the nozzle 145 rises vertically. As a result, the inlet of the nozzle 145 is opened to spray water on the crops, thereby preventing the crops from dying due to lack of moisture.
