| 中文摘要: |
| 针对目前用于检定翻斗雨量计的流量式标准仪器以及采用与雨滴性质相近的玻璃球模拟降水粒子并不能对光学降水现象仪探测性能进行检验的问题。设计了一款基于STM32为数据处理与控制核心的降水现象仪检测系统，通过可控速度的圆盘调节模拟粒子速度，以及在圆盘上贴有不同直径大小的贴片来模拟粒子大小的方法，用以检验光学降水现象仪检验降水粒子速度与尺度的效果。实验表明，该设计可以同时控制模拟降水的下落速度和尺度大小，对检验和衡量雨滴谱仪的测量准确性以及性能判定具有重要现实价值。 |

| Aiming at the problem that the current flow standard instrument used to test the tipping bucket gauge or using glass ball with similar rain drop property is not possible to detect the optical raindrop spectrometer, we design a detection device for raindrop spectrometer based on STM32, which processes data and control system, adjusts the velocity of particles by controlling the speed of the disk, and pastes the discs with different diameters on the disc to simulate the particle size. And it is used to test the optical raindrop spectrometer whether can judge precipitation particle velocity and scale. The experiments show that the falling velocity and size of the simulated precipitation can be controlled at the same time, and the design has important practical value to test and measure the accuracy and performance of the raindrop spectrometer. |
