Cloud-based monitoring and controlling system for the growth environment of multi-variety vegetable plant factories

Abstract

The control of PH and EC in the nutrient solution of hydroponic plant factories is a key factor affecting the yield and quality of plants. In this paper, a cloud-based system for environmental factors in plant factories is studied for the need of real-time, remote, automatic and accurate monitoring and controlling of PH and EC values of nutrient solution in multi-species vegetable hydroponic plant factories. The system includes information acquisition module, data transmission module, remote monitoring module, local control and execution module, which can realize information monitoring and control of nutrient solution environmental data of multi-equipment and multi-species vegetables in plant factories. Real-time data monitoring and control of PH and EC values in nutrient solution can be carried out both remotely and on site. Meanwhile, the automatic control of PH and EC values in nutrient solution based on PID algorithm ensures that each environmental factor is in the target range suitable for plant growth. The test results show that the system is stable and reliable, and can realize intelligent detection and control of nutrient solution environment in multiple areas of plant factories.
