摘要
提出了一种新的测风方法。利用热元件散热-温度函数关系，研制了坦克射击固态风速传感器。传感器内采用恒压加热和温敏为一体的专用检测元件，补偿的数据查表技术，提高了传感器测风精度，消除了环境温度的影响，达到了固态没风仪的设想，满足了坦克射击的苛刻要求。分析表明：选择恒压加热器为热源，温敏元件为测风元件，EPROM作为补偿表格的方式，可满足设计要求。传感器精度优于0．5％，比转轮式测风传感器精度提高了一个数量级。
A new method for wind velocity detection is proposed' A solid state anemometer is used. The sensor uses a constant voltage, datum processing compensa-tion, and can thus get rid of detrimental influences caused by ambient temperature conditions. To meet the demand for the solid state anemometer, and excessive demands under gun-fire, an EPROM compensation table based on a mathematical model is given. The precision of this device is proved to be within 0.5 % .
