Research And Implementation Of Agricultural Greenhouse IoT Environment Monitoring System Based On OneNET

The concept of the Internet of things was born at the end of the last century,after a short period of more than 10 years of rapid development,the application of the Internet of things has been extended to all aspects of people's life,is constantly affecting the production and lifestyle of mankind,will set off another wave of human information industry development.Agricultural iot technology has promoted the rapid development of China's modern agriculture,and the agricultural iot greenhouse technology has also been widely used in China.Intelligent agricultural greenhouses based on the Internet of things are the new trend of future agricultural greenhouses development,which conforms to the development requirements of "Internet +" agriculture and has extremely broad application prospects in the future.At present,the domestic intelligent agriculture greenhouse system is affected by the traditional Internet of things thinking.Most design schemes have complex structure,high development cost and long development cycle,such as a system with ZigBee network,ARM,communication module,cloud server.This paper designs an agricultural greenhouse Internet of things environmental monitoring system based on OneNET,which adopts the Internet of things module ESP8266 and the OneNET Internet of things cloud platform launched by China mobile,and develops intelligent terminal and remote upper control terminal.The system utilizes embedded development technology,TCP/IP network protocol,adopts OneNET cloud platform,uses EDP protocol as access mode,ESP8266 module as communication module,STM32 master controller as intelligent terminal,external temperature and humidity sensor and terminal.The equipment has successfully realized the ecological factor monitoring and remote control of equipment in agricultural greenhouses.The Kalman filter algorithm is used to filter the collected data to reduce noise interference and random errors during data acquisition,and improve data accuracy.The filtered data is uploaded to the OneNET cloud platform,and the cloud platform UI interface and the user system web side aredesigned to realize real-time monitoring and remote control.At the same time,the device cloud APP launched by OneNET can realize remote monitoring anytime and anywhere.The agricultural greenhouse environmental monitoring system has undergone several functional tests,the system design is reasonable,and the various functions of the system are stable.Users can use various methods to realize remote monitoring and control of the environment conveniently and quickly.At the same time,the system is a new type of agricultural Internet of Things system with modular design.Compared with the traditional agricultural IoT solution,the development cycle is short,the development cost is low,and the operation is simple.It can be suitable for intelligent monitoring and management of various application scenarios.
