| 摘 要： | 鉴于微型计算机对数据采集和处理具有速度快、精度高和便于自动化的特点,我们研制了应用单板微型计算机自动测试风速仪的动态参数(时间常数、距离常数等)的测试系统。该系统的主要特点是能够对测试参数进行自动、连续和多次重复测定并实时获取参数的平均量,测得的时间常数的精度可达到毫秒数量级。本文介绍了该系统的基本组成、测试原理和方法,应用该系统对EY_1型电传风向风速仪和QDF型热球电风速计的距离常数和时间常数进行了测试,并给出测试结果,测试表明,在风洞内和在空旷的房间内在一定的风速下,两者分别测得的风速仪动态参数值十分相近

| Abstract: | A new method of measuring the dynamie parameters of the anemometer is presented. The measurement system can measure the time-constants of the anemometer not only for increasing wind-speed (tup) but also for decreasing wind-speed (tdown) and the distance constant L of the anemometer. A microcomputer system is used for system controlling and data processing and displaying.The precision and resolution of the measured time-constants are 0. 05 sec and 0. 01 sec, respectively. |
