영문 초록

The conventional nutrient automatic feeder of the venturi type controls the target value by receiving the feedback through the sensor (EC or PH) by the control method in which the liquid is ejected by blowing air with ON / OFF time. however the nutrient solution can not be continuously injected and it is impossible to control the ratio of the nutrient supply reservoir by re-adjustment and if sensor (EC or PH) fails, nutrient supply is not possible and the concentration change is severe. By compensating for these disadvantages and changing to the improved high-pressure pump input method, a certain amount of nutrient solution was realized and accurate nutrient concentration control is possible by continuous control, and the amount of water can be adjusted by the nutrient supply tank control. The size of the equipment was reduced by reducing the number of parts, and it was made to be convenient to use at the same time as reducing the cost. And it was possible to control the concentration of the nutrient solution accurately by continuous control and to adjust the amount of water by the nutrient supply water tank ratio control. In addition, the sensor can be operated manually in case of sensor failure, and a certain amount of nutrient solution is supplied to the plant by the accurate concentration control of the continuous control, so that the plant that has been supplied with it can grow well. The fault monitoring function was added to this, so that the automatic control technology was popularized in agriculture and used conveniently.
