Design of Intelligent Agricultural Greenhouse Monitoring System Based on Kalman Filter
In order to solve the problems of difficult acquisition of environmental parameters,complex wiring and high cost in traditional agricultural greenhouses,an intelligent agricultural greenhouses monitoring system based on Kalman filter is designed.The system collects information through soil moisture,temperature and humidity and light sensors,and then transmits the data to the main controller of STM32 MCU by ZigBee wireless transmission module for processing and analysis.At the same time,the detection results are sent to the upper computer to realize remote real-time monitoring of agricultural greenhouses.Kalman filtering algorithm is used to filter and denoise the monitoring data,which improves the measurement accuracy and reduces the error.The experimental results show that compared with the traditional agricultural greenhouse,the design can effectively improve the automation and in-telligent level of the greenhouse.When the external environment changes,the system can respond timely and accu-rately and send out corresponding warning signals,reducing losses caused by bad weather,and can be widely used in modern agricultural production and management fields.
