基于一元线性回归由风速传感器测量值推导巷道平均风速

Average Wind Speed of Roadway from Measurements of Wind Speed Sensor Based on One-dimensional Linear Regression

通过试验数据建立了风速传感器的测量值与平均风速之间的一元线性回归方程,并对拟合效果进行了评价。对参数的判断表明该方程是有效的,可以近似地把风速传感器的测量值转换成平均风速值,并在相同的巷道长度、相同的风流速度、不同断面下用Comsol模拟了风速流场分布情况。

One-dimensional linear regression equation between measured value of wind speed sensor and the average wind speed is established by experimental data. Its effect is evaluated. Judging the parameters, the equation is proved to be valid. With the equation, the measurements of wind speed sensor can be approximately converted to the average wind speed. And the distribution of wind speed field is simulated with Comsol in the conditions of the same length of roadway,the same wind speed and different sections.
