Design of smart agricultural data acquisition system for blueberries based on internet of things and multi-sensor fusion
摘要
Abstract
To address specific requirements of blueberry plant factories,a smart agricultural data acquisition system for blueberries has been designed based on internet of things and multi-sensor fusion technologies.System was comprised of two main components,includ-ing a local device controller and a cloud-based remote control platform.Local controller was developed based on STM32F4 series chip and FreeRTOS operating system,adopted an RS485 interface and Modbus-RTU communication protocol.It utilized an industrial con-trol touchscreen to achieve real-time environmental parameter monitoring and on-site equipment control.Cloud-based remote control platform utilized MQTT communication protocol to interconnect with local controllers,to provide remote monitoring,historical data queries,and data export capabilities.System achieved comprehensive monitoring of blueberry growth environment through integration of multiple sensors,including a 485-type CO2/temperature/humidity transmitter(RS-CO2WS-N01-2)and a 485-type temperature/hu-midity/electrical conductivity/pH sensor(RS-ECTHPH-N01-TR-1).Test results demonstrated that system could rapidly respond to pre-set temperature requirements of blueberry plant factory and maintain environmental temperature deviations within±1 ℃,delivering out-standing performance in practical applications.关键词
