为明确风速传感器在检定过程中受到检定环境如温度、湿度和气压所带来的影响，依据《JJG4312014轻便三杯风向风速表检定规程》对轻便三杯风向风速传感器进行检定，通过标准风速计算公式分析空气温度、湿度和气压检定前后的变化对检定结果的影响，运用加权计算方法计算得出检定过程中温度、湿度和气压各自所占权重，经过实验验证比对，结果表明通过分析研究温、湿度和气压对于标准风速值的影响，使风速传感器检定的准确性得到显著提高，减小了测量不确定度。
In order to clarify the influence of temperature, humidity and air pressure on the verification environment for the wind speed sensor, According to "JJG4312014 Portable 3cup anemometers" verification the speed sensors, through the formula for computing the standard wind speed analysis of air temperature, humidity and air pressure changes before and after verification on the result of test, the calculated by weighted calculation method verification of temperature, humidity and air pressure in the process of their weight, through experiment, the experimental results show that through the analysis and research on the influence of temperature, humidity and air pressure values on the wind speed standard , the wind speed sensor calibration accuracy is increased significantly, reduce the uncertainty of measurement.
