The present invention relates to a training system for implementing a nutrient solution irrigation system for agricultural-based convergence technology education, and to a system for training the agricultural electricity and Arduino convergence technology required in the agricultural field.

Domestic agriculture, which is suffering from a decrease in the proportion of agricultural land, manpower, and production, is currently transforming into'smart agriculture' by fusion with advanced technologies. In recent years, agriculture is evolving in a form in which cutting-edge technologies such as information and communication technology (ICT), biotechnology (BT), and green technology (GT) are converged. For example, the smart farm greenhouse is transforming into a high-tech convergence of electricity, electronics, machinery, and IoT based on horticulture.

Therefore, research on essential agricultural convergence technology is in full swing centered on local agricultural organizations, and various smart farm technology education programs for farmers are provided by specialized institutions such as the Agricultural Garden.

However, since some of the leading farmers are the main focus, most of the elderly farmers are unable to adapt to the heterogeneous technological environment. Accordingly, there is an increasing need to provide an educational environment familiar with essential agricultural convergence technologies from the time of specialized high schools in the agricultural field.

The second method is a method using an Arduino control device that implements all the control functions and signal transmission systems of the sequence controller equivalently with Arduino technology. As is known, arduino refers to a board that can connect various sensors or parts and includes input/output and central processing unit. Although not at the level of a computer, it is a very basic system capable of executing and processing commands. It refers to the arithmetic board with devices. Therefore, the Arduino can receive input values from various switches or sensors and control the output with electronic devices such as LEDs and motors.

Hereinafter, in the description, the second method, a production practice device for a nutrient solution irrigation system for agricultural-based convergence technology education using an Arduino control device, will be described in more detail.

Therefore, the A liquid manure from the A liquid reservoir 150 is introduced into the mixing vessel 140 along the A liquid reservoir 12, and the B liquid manure from the B liquid reservoir 150 is along the B liquid reservoir 12 and the mixing vessel 140 ).

The irrigation hose 13 is a hose connecting the mixing tank 140 and the irrigation role tank 160. Therefore, the nutrient solution in the mixing tank 140 flows into the irrigation role tank 160 along the irrigation hose 13.

The individual pump P is a pump that pumps for liquid movement in each hose. For example, the first pump pumps the water from the raw water tank 130 to flow into the mixing tank 140 along the raw water hose 11 according to the pump control signal, and the second pump pumps the liquid bottle ( The liquid manure of 150) is pumped so that it flows into the mixing tank 140 along the liquid rain hose 12, and in the third pump, the nutrient solution of the mixing tank 140 plays a role of irrigation along the irrigation hose 13 according to the pump control signal. Pumping is carried out so that it flows into the barrel 160.

The water tank side control signal terminal 110 is a terminal that receives driving power and receives a pump control signal. Since it is in the form of a port, it can be easily attached and detached through the connecting connection of the sensing signal connection line 320.

The water level detection sensor 141 is a sensor that senses the level of the nutrient solution contained in the mixing container 140 to generate a nutrient solution level signal.

Meanwhile, the Arduino control device 200 may be implemented in an automatic generation method or a manual generation method in generating a pumping control signal.

To this end, the Arduino control device 200 includes a mode selection switch (not shown) for selecting an automatic control mode or a manual control mode.

When the automatic control mode is selected through a mode selection switch (not shown), it operates in an automatic control mode. When operating in such an automatic control mode, the Arduino board 230 receives it through the Arduino-side sensing signal terminal 220. The pumping control signal is automatically generated according to the one nutrient level signal. For example, when the nutrient solution contained in the mixing container 140 is less than a preset reference level, a pumping control signal is generated so that the raw liquid in the raw water container 130 and the liquid fertilizer in the liquid reservoir 150 flow into the mixing container 140 by operating the pump. Generate. Therefore, the nutrient solution in the mixing vessel 140 can be automatically manufactured according to the reference water level set by the user, thereby enhancing user convenience.

When operating in such a manual control mode, the Arduino board 230 responds to the pressing of the pump operation button 250. It generates a pumping control signal according to it. Here, the pumping operation button is a plurality of buttons for receiving input of each individual pump operation from a user.

In addition, when the manual control mode is selected through a mode selection switch (not shown), manual control may be performed separately through a user terminal. Here, the user terminal may correspond to a smartphone, a tablet, a desktop PC, and a notebook. As shown in FIG. 7, the user terminal generates a pumping control signal according to the pumping control input from the user through Bluetooth communication with the Arduino control device 200 and transmits it to the Arduino control device 200.

To this end, the Arduino control device 200 includes a Bluetooth communication module 260 for Bluetooth communication with a user terminal, and the Arduino board 230 connects the Bluetooth communication module 260 when operating in a manual control mode. Through the pumping control signal received from the user terminal is transmitted.
