基于ARM和GPRS的远程土壤墒情监测预报系统
Remote monitoring and forecasting system of soil moisture based on ARM and GPRS
摘要
Abstract
The GPRS wireless soil moisture monitoring and forecasting system was designed to improve the utilization rate of farm irrigation water and achieve water-saving irrigation, a mathematical model of soil moisture monitoring and forecasting was presented, and a data acquisition system composed of the S3C2410 processor, GPRS module and CS8900a card was developed. The system had the functions of automatic collection, storage, and wireless transmission of soil moisture data, and performed irrigation tasks according to soil moisture data at a specified time and a given amount of water. The system was used for 15 months in the agricultural demonstration base station in Beijing. Experiments show that the error of the forecast value and actual test data is 3.39%, and therefore the system has achieved effective soil moisture monitoring and accurate forecasting of soil moisture.关键词
