微型电脑应用

传统气象站中人工观测的数据不精确、自动化水平低，为此提出了基于STM32单片机和ESP8266 Wi-Fi通信模块的便携式小型智能气象站方案。通过下位机和上位机两部分构成智能气象站系统，其中下位机包括以STM32F103最小系统为核心的主控器，集成气象数据采集模块、电源模块以及ESP8266 Wi-Fi通信模块。多个传感器主要用于采集气象数据，经由RS485总线输送至STM32主控器中，经过处理后再通过Wi-Fi远程传输到上位机云平台。上位机主要以云平台为依托，用来实现气象数据分析、系统数据导出、气象灾害与极端天气报警、数据可视化显示等功能。经过测试，所设计的智能气象站具有低功耗、操作简单、安全可靠、便携的特点。

Aiming at the problems of inaccurate data and low automation level of manual observation in traditional weather stations, a portable small intelligent weather station scheme based on STM32 single chip microcontroller and ESP8266 Wi-Fi communication module is proposed. The intelligent weather station system is formed by two parts of the lower computer and the upper computer. The lower computer includes the main controller with the STM32F103 minimum system as the core, integrates weather data acquisition module, power supply module and ESP8266 Wi-Fi communication module. Multiple sensors are mainly used to collect meteorological data, they are sent to the STM32 main controller via the RS485 bus, and then transmitted to the upper computer cloud platform via Wi-Fi after processing. The upper computer is mainly based on the cloud platform to realize meteorological data analysis, system data exit, meteorological disasters and extreme weather alarms, data visualization display and other functions. After testing, the designed intelligent weather station has the characteristics of low power consumption, simple operation, safety and reliability, and portability.
