摘要
根据地面气象观测规范对日照的观测要求,文章提出将日照计传感器感应单元和数据采集处理单元集成于一体,基于MSP430F149微控制器设计了一种新型光电式自动数字日照计。文章介绍了系统总体设计方案,描述了数据采集处理单元硬件和程序设计。系统最后经过与已标定的直接辐射表进行观测数据对比试验,分析得出该日照计能够比较精确地感应太阳辐射的变化。
According to surface meteorological observation standards for the requirements of sunshine observation,it is proposed to integrate the sensor unit of the sunshine sensor and the data acquisition and processing unit into one,a new type of photoelectric automatic digital sunshine meter is designed based on MSP430F149 microcontroller.The overall design plan of the system is introduced,and the hardware and program design of the data acquisition and processing unit are described.Finally,the system is compared with the calibrated direct radiation meter,and the analysis shows that the solar radiation change can be more accurately induced by the sunshine recorder.
