内容：
道面温度是道面气象要素之一,也是判断道路表面状态的重要依据。测量道面温度的非接触式红外测温系统基于全辐射测温法,用热释电探测器接收道面红外辐射进行系统整体设计及数据分析,分别采用最小二乘法和BP神经网络算法进行标定。结果表明:三层BP神经网络的拟合效果较好,系统测量误差在1%以内。通过外场实验并与PT100对比,相关系数达到0.999,能实现对道面温度的精准测量。 Pavement temperature is one of the meteorological elements of the pavement, but also an important basis for judging the state of the road surface. The non-contact infrared temperature measurement system for measuring the pavement temperature is based on the whole radiation temperature measurement method. The whole system design and data analysis are carried out by using the pyroelectric detector to receive the infrared radiation. The least squares method and the BP neural network algorithm are used to calibrate The The results show that the three-layer BP neural network has better fitting effect, and the system measurement error is less than 1%. Through the field experiment and with the PT100 contrast, the correlation coefficient of 0.999, can achieve accurate measurement of the pavement temperature.
