摘要
设计一套基于STM32嵌入式微处理器的农业气象物联网数据采集系统,包含微处理器、系统供电模块、数据采集模块、GPS模块、无线通信模块、外部Flash存储器和LCD触摸显示屏等部分。系统在安徽省56个市县进行了监测实验与示范,结果表明:监测基站与软件平台运行稳定;采集的农业气象数据基本完整,没有出现明显的数据包缺失情况;数据变化的趋势与当地的农业气象信息一致,且与利用实验室标准仪器检测结果偏差较小,能够准确地监测农业生产现场的农业气象情况。
A data acquisition system for agricultural meteorological IOT based on STM32 processor is proposed,including microprocessor,power-supply module,sensors,GPS＆GPRS,Flash memory and LCD touch screen. Experiments and demonstrations are conducted in 56 cities and counties of Anhui province. The results show that the monitoring system is operating stably; the collected data are complete and there is no obvious packet loss; the trend of data changing is consistent with the local agro-meteorological information,and it has a small deviation to the test results that using laboratory-standard instruments. The system can accurately monitor the agricultural meteorological conditions at the agricultural production site.
