Abstract

The invention provides a plant factory nutrient solution detection and regulation system, and relates to the field of nutrient solution automation and intelligent regulation in plant factories. The system comprises a three-dimensional culture device, a detection device, a regulation device, a circulation device and a control system. The detection device comprises a sensor installed in a cultivation tank to obtain a nutrient solution index value in real time; the regulation device comprises a mother liquid tank and an electromagnetic water valve for adjusting components of the nutrient solution, a stirring device for uniformly mixing the nutrient solution, a temperature controller and an aerator for adjusting temperature and dissolved oxygen amount; and the circulation device comprises a conveying pipe for completing intermittent circulating flow of the nutrient solution and a water pump for providing power. The indicator value signal is obtained through the detection device, the circulation device and the regulation device are controlled to work after being processed by the control system, and the circulation and the regulation operation of the nutrient solution are completed. Thesystem has simple structure and convenient use, improves speed and precision of detection and regulation of the nutrient solution, and improves quality and yield of crops.

Description

technical field [0001] This patent relates to a nutrient solution control system, in particular to a plant factory nutrient solution detection and control system. Background technique [0002] Plant factory is an advanced form of emerging modern facility agriculture. It is an efficient agricultural system that can realize annual continuous production of crops. At present, plant factories in my country mainly use nutrient solution cultivation to cultivate crops. The core of nutrient solution hydroponics technology is nutrient solution, which can directly affect the growth of crops and is an important factor affecting crop quality and yield. The current detection and control of nutrient solution is mostly done manually and with simple equipment, which is low in precision, time-consuming, laborious, and inefficient, and cannot adapt to the intelligent operation of plant factories. With the development of intelligent control technology and the improvement of people's requiremen...
