摘要

降水粒子测量是气象观测要素中重要的组成部分。提出了一种基于压电传感器的新型感测方法

并依此设计了一种基于现场可编程门阵列（FPGA）的降水粒子信号采集处理系统。该系统对信号进行多路同步采集

并利用拟合所得的各路系统响应函数与各粒子响应函数实现对粒子的测量。系统实现信号全量程采集的同时有效降低了非线性误差。实验结果表明:该系统对于粒子直径观测误差小于±0.1 mm

具有量程宽、精度高、响应快、粒子判别准确等特点。

Abstract

Precipitation particle measurement is an important section in meteorological observation.Propose a new method of measurement

which is based on piezoelectric sensor

and a kind of FPGA-based precipitation particle signal acquisition and processing system is designed.This system acquires signal through synchronized multi- channel

and use response function of each channel system and response function of each particle obtained by fitting to realize measurement on particle.The system not only realizes full scale acquisition but also effectively reduces nonlinear error.Experimental results indicate that observation error of the system on particle diameter is less than ± 0.1 mm and it has features of wide scale

high precision

fast response and accurate particle discrimination.
