Description
A Dripper Blockage Detection System for Nutrient Solution Supply Drippers in a Smart Greenhouse The present invention relates to a nutrient solution supply dripper clogging detection system for a smart greenhouse that checks for dripper clogging in real time and enables immediate and rapid response. A smart greenhouse cultivation system is a system that creates an artificial environment to enable crop cultivation regardless of natural environmental conditions. By controlling temperature, humidity, and light intensity, it provides an optimal environment for crop growth, thereby increasing productivity and improving quality. Smart greenhouse cultivation systems utilize a nutrient solution supply system to efficiently provide the nutrients and water necessary for crop growth. The nutrient solution supply system consists of a nutrient solution tank, pump, pipes, and drippers. The nutrient solution stored in the tank is supplied through pipes to drippers installed in the growing medium using a pump. The drippers discharge the nutrient solution through fine holes in a drip-type manner, supplying it directly to the crop roots. Afterwards, any excess nutrient solution remaining after being absorbed through the roots of the crop is discharged and processed through the drainage holes of the growing medium. Meanwhile, one of the major problems with the nutrient solution supply system is dripper clogging. If the dripper becomes clogged, the nutrient solution supply becomes uneven, causing problems such as reduced crop growth and lower quality. At this point, the causes of dripper clogging can be broadly divided into three categories. First, the mixing of foreign substances can cause fine particles or sediment contained in the nutrient solution to clog the inside of the dripper. Second, biological contamination can cause microorganisms to proliferate in the nutrient solution system and clog the dripper. Third, minerals in the nutrient solution can settle inside the dripper and cause clogging. It is difficult for administrators to monitor these issues in real time, which can make prompt response difficult. In addition, it causes the inconvenience of requiring the administrator to periodically check whether the dripper is clogged. Accordingly, there is the inconvenience of having to frequently inspect and clean the dripper, and in some cases, there is a problem of incurring costs because the dripper must be replaced outside the maintenance cycle. In particular, when the greenhouse is large or there are many drippers, such maintenance work poses a problem requiring significant time and cost, which can lead to poor crop growth and economic losses for farmers.
