摘　　要：作者在ＴＳＭ－１型电风速计的基础上，应用单片机技术，研制开发的双测头智能化的数字微风速计。该仪器灵敏度高，响应时间快，可同时检测Ｘ、Ｙ方向的风速，并可设定采样和积分时间，具有数据存储功能，经数据处理，在键盘的控制下，可以分别显示风速的瞬时值、平均值，打印测量结果，以满足现场测试的要求。该仪器性能稳定，测量范围０．０５～５ｍ／ｓ，测量精度优于５％，分辨率０．０１ｍ／ｓ，现已小批量生产。Measurement of air velocity is widely applied in fields of scientific research and manufacture.But at present in China,most of the anemometers are function fixed,and only capable of measuring in single direction at a time.According to the practical requirements in tobacco industry and other fields,Type YSJ 1 dual probe intelligent digital anemometer has been designed for measuring lower air velocity(ranging from 0 05～5 m/s,calibrated accuracy ±5%).The YSJ 1 is developed from TSM 1 electronic anemometer by applying singlechip microcontroler technique and the design of dual probe.This instrument has the features of high sensitivity and short response time while monitoring air velocity simutaneously in both X and Y directions.Under the control of microprocessor,signals from two detectors are converted to digital data and calculated into average value.Measuring results can be stored in a 8Kb memory unit.Sampling frequency,integrating period and data processing method are programable.With selection from keypad,instantaneous value and average value of air velocity in each direction can be displayed on LCD or printed out by commands from keypad.This instrument is of stable performance and quite convenient for field testing.
