Nutrient automatic supply device and control method |
| abstract |
Disclosed are an automatic nutrient solution supplying device and a control method thereof capable of precisely and quickly adjusting the transition temperature concentration and acidity of nutrient solution. The nutrient solution automatic feeding device is a raw water supply pipe for supplying raw water, a tube pump for supplying fertilizer liquid from a fertilizer liquid storage tank in which fertilizer liquid is stored, and a nutrient solution discharge pipe in which nutrient solution mixed with raw water and fertilizer liquid are discharged. It is installed in the sensing sensor for measuring the physical properties of the nutrient solution discharged to the nutrient solution discharge pipe, and includes a pipe ratio control unit for controlling the amount of fertilizer liquid supply by the tube pump receiving the signal measured by the sensor. By such a configuration, the rotational speed of the tube pump is automatically changed according to the physical properties of the nutrient solution supplied through the nutrient solution discharge pipe, and the fertilizer liquid supply amount to the raw water supply pipe can be adjusted quickly and precisely. |
