Design And Research Of Temperature And Humidity Monitoring System Based On Cloud Platform

The "cloud platform" is an IT resource delivery model that has emerged along with the development of Internet technology.The purpose of the cloud platform is to enable users to use IT resources like water,electricity and coal.The application of cloud platform technology,embedded technology,Internet technology,and data analysis to agricultural greenhouse production decision-making and monitoring and control is a modern wisdom agricultural production,is an indispensable technical force to improve China's agricultural productivity.At present,China's agricultural modernization compared to some developed countries in Europe and America,China's current greenhouse production automation monitoring level is still at a low stage.Compared with the world's most advanced agricultural production countries,there is still a certain gap,among which,there is a clear gap in the monitoring and control technology of the basic growing environment of crops.The topic of this study is to study the relative importance of temperature and humidity,two extremely important crop growth environmental parameters,and to remotely monitor and control temperature and humidity in the context of agricultural greenhouse production.Therefore based on the independent research and development of the unique natural environment and geographical factors in Yunnan Province,the project has designed a set of low-cost,easy-to-install,easy-to-test and maintenance-friendly greenhouse planters suitable for the current crop planting production.Humidity monitoring system.Design The main control module is STM32F107 with Cortex-M3 as the core.Use the Wi-Fi communication module,GSM/GPRS communication module,and W5500 Ethernet communication module to access the cloud server to build the cloud platform.Build it with the SM1810 B temperature and humidity sensor.Perceive the network layer and design a temperature monitoring system based on the cloud platform.The entire monitoring system is composed of multiple temperature and humidity smart sensors,MCU main control terminals,cloud servers,and smart terminals distributed in the shed.The temperature and humidity sensors use the RS-485 bus technology based on the industrial Modbus field bus protocol.The main control module reads and preprocesses,and then the data is transmitted to the cloud server for storage,processing and analysis in real time through various communication modules,authorizing agricultural production personnel to require less personal intelligence when the computer application capability is uneven.Terminals(PCs,smart phones,and PDAs)view the data stored in the cloud server through the smart terminal APP to remotely monitor and control the temperature and humidity in the greenhouse.This subject provides a good open cloud platform for the "Internet +" development of the crop planting industry.
