摘　　要：本文介绍了一种风压传感器的设计方案,其中包括控制板、控制板固定座、传感器壳体和压力膜。通过使用非接触的红外测距方式检测压力膜的形变量,根据形变量换算出风压信息,并使用最小二乘法对传感器输出值进行温度补偿,有效提高了信号检测精度,同时降低了传感器个体差异和故障率。This article introduces a design scheme of wind pressure sensor,including control board,control board fixed seat,sensor shell and pressure film.By using the non-contact infrared ranging method to detect the shape variable of the pressure film,the wind pressure information is calculated according to the shape variable,and the temperature compensation of the output value of the sensor is carried out by using the ordinary least squares,the signal detection accuracy is effectively improved,and the individual difference and failure rate of the sensor are reduced.
