Abstract

Abstract:

To achieve accurate measurement and control of the important factors that affect crop growth in soilless culture nutrient solution, an information monitoring system of soilless culture nutrient solution in greenhouse based on cloud platform was proposed in this paper. This system consisted of acquisition module, control module, cloud platform and application terminal. To be specific, firstly, the sensor was used to timely measure the information of the influencing factors, including conductivity, pH, and temperature, level and oxygen content of the nutrient solution. Then, the data was integrated, processed and transmitted to the control module and Ali cloud platform for data preservation through wireless communication module. Finally, the information changes of the nutrient solution could be monitored in real time by means of the Web terminal. The experimental results revealed that the system proposed in this paper could accurately monitor the information of nutrient solution in good time, provide feedback information of nutrient solution needed by crops reasonably, and meet the requirements of functional design. Moreover, this system showed certain practical values with low cost.

Key words: soilless culture, nutrient solution information, acquisition system, cloud storage, system design
