基于ARM的自动气象站数据实时显示系统

摘要

提出一种基于ARM的自动气象站本地数据实时显示系统,该系统使用STM32微处理器作为主控制器,利用RS232串口和Zigbee无线传感器网络主动获取自动气象站采集的实时数据,最终使用LED屏幕显示数据.在Keil u Vision4和IAR Embedded Workbench开发环境下,使用C编程语言进行开发.实际测试效果表明,该系统将气温、相对湿度、能见度等本地气象数据实时的、直观的、稳定的显示在LED屏幕上,方便人们快速掌握当地的气象情况,适用于景区、高速公路、船舶等多种场景.%In this study, an ARM-based real-time local data display system for automatic weather stations is proposed. This system uses an STM32 microprocessor as the main controller as well as an RS232 port and Zigbee wireless sensor network to automatically acquire real-time data collected by automatic weather stations. Finally, the data are displayed through a light emitting diode (LED) screen.This system was developed using the C programming language in the Keil u Vision4 and IAR Embedded Workbench development environments. Actual test results reveal that the proposed system can present local meteorological data such as temperature, relative humidity, and visibility through LED displays in real time and in an intuitive and steady manner. This system enables persons to understand local meteorological conditions quickly and can be used in various locations such as scenic locations, highspeed highways, and ships.
