摘 要: 为便于测量某一地点的太阳光照强度,设计了以STM32作为主控制器的太阳光照强度测量系统。该系统采用多模块单核心的系统架构,由光电二极管、高速AD转换器等电路实现太阳光照强度的采集,并且采用全球定位系统(global positioning system,GPS)/北斗模块同时测量经纬度以及海拔高度,测量信息由液晶显示屏(liquid crystal display,LCD)实时显示。测量数据存入单片机中的EEPROM中,并通过串口发送到上位机,并由应用软件将测量点位置信息和光照强度信息显示在地图上。使用Matlab数据拟合来减小测量误差。该系统具有性价比高、功能全面且易于拓展等特点,具有较强的应用价值。
关 键 词: 信息处理技术;STM32嵌入式开发;光照强度;GPS/北斗定位;数据拟合

Abstract: For the convenience of measuring the solar illumination intensity of a certain location, a solar illumination intensity measurement system with STM32 as the main controller is designed. The system adopts a multi-module single-core system architecture, which realizes the acquisition of solar illumination intensity by photodiode, high-speed AD converter and other circuits. The global positioning system (GPS)/Beidou module is used to measure the longitude, latitude and altitude simultaneously, and the measurement information is displayed by the liquid crystal display (LCD) in real time. The measurement data is stored in the EEPROM of the single chip microcomputer and sent to the upper computer through the serial port, and the information of the measuring point position and the solar illumination intensity is displayed on the map by the application software. Matlab data fitting is used to reduce the measurement error. The system has the characteristics of high cost performance, comprehensive function and easy to expand, and has strong application value.
