一种用于天文台选址的气象参数和大气湍流测量系统
A Meteorological Parameter and Atmospheric Turbulence Measurement System for Locating Astronomical Observatory
摘要
本文提出一种用VFC(电压-频率变换器)进行模数转换的气象参数和温度脉动测量系统.系统安装在云南天文台高美古观测站一27m高铁塔上,包括三层金属丝温度脉动传感器和温度、湿度、气压、风速、风向传感器.用计算机选通多路开关,8253计数器对脉冲信号计数,实时测量和显示数据.成本低,能保证长距离数据采集的精度.
Abstract
A meteorologicalparameter and atmospheric turbulence measurement system was described in this paper. A/Dconversion was done by VFC (Voltage Frequency Changer). The system has been implemented ata 27 m tower in Gaomeigu Yunnan Astronomical Observatory,that includes three levelsfast-response temperature sensors and two slow-response temperature sensors,a humiditysensor,a pressure sensor,a propeller-vane anemometer,Computer selects input channelsand pulse signal is counted by 8253 counter,so the system cost is low and the measuringprecision of long distance sampling signal can be ensured.
