摘要
蒸发量是气象观测领域重要的气象要素之一。为实现蒸发数据的自动观测,使用单片机设计了一种新型高精度蒸发自动观测仪。蒸发自动观测仪主要采用称重式原理对蒸发数据进行探测,通过蒸发皿中水的重量计算出水的高度,根据水高度的变化计算出不同时刻的蒸发量。为保证蒸发自动观测仪观测数据的准确性和稳定性,添加数据优化处理算法,针对蒸发传感器的日常使用环境,添加对应的结构防护措施和软件规避措施。户外安装对比试验结果表明,蒸发自动观测仪计算数据与人工观测数据基本一致,满足蒸发自动观测仪测量精度高、环境适应性强、具有实时性、可自动观测数据的设计要求。该观测仪为蒸发数据在气候监测、环境监测、生态监测、水利监测、农业生产和遥感验证等领域提供了支撑和保障。
Evaporation is one of the important meteorological elements in the field of meteorological observation.To realize the automatic observation of evaporation data,a new type of high-precision evaporation automatic observatory is designed by using a microcontroller.The evaporation automatic observatory mainly adopts the principle of weighing to detect the evaporation data,calculates the height of water through the weight of water in the evaporation dish,and calculates the evaporation at different moments according to the change of water height.To ensure the accuracy and stability of the observed data of the evaporation automatic observatory,data optimization processing algorithms are added,and corresponding structural protection measures and software avoidance measures are added for the daily use environment of the evaporation sensor.Outdoor installation comparison test results show that the evaporation automatic observatory calculated data and manual observation data are basically the same,to meet the design requirements of evaporation automatic observatory of high measurement accuracy,strong environmental adaptability,real-time,automatic observation data.The observatory provides support and guarantee for evaporation data in the fields of climate monitoring,environmental monitoring,ecological monitoring,water conservancy monitoring,agricultural production,and remote sensing verification.
