摘　　要：针对无人机开展高空气象探测的需求,本文设计了一种带防辐射罩铠装铂电阻温度传感器。首先,采用计算流体动力学(CFD)的方法计算出有无防辐射罩铠装铂电阻温度传感器在多物理场下的太阳辐射误差,并进行对比分析。然后,使用支持向量机(SVM)和粒子群优化支持向量机(PSO-SVM)算法训练数据比较预测模型。最后,搭建低气压风洞实验平台模拟高空大气环境,对比实验数据与算法预测结果。实验表明,本文提出的带防辐射罩铠装铂电阻温度传感器测量的平均误差为0.0141 K,均方根误差为0.0150 K。Aiming at the demand of UAV for high-altitude weather detection,in this paper,an armoured platinum resistance temperature sensor with radiation shield is designed.Firstly,a computational fluid dynamics(CFD)approach was employed to work out the solar radiation error of armoured platinum resistance temperature sensors with or without radiation shield under multi-physical fields,and the comparative analysis was carried out.Then,Support Vector Machine(SVM)and Particle Swarm Optimization Support Vector Machine(PSO-SVM)algorithms were used for training data to compare the the forecast models.Finally,a low-pressure wind tunnel experimental setup was constructed for simulating the upper atmosphere environment,and the experimental data and the algorithm prediction results were compared.The experimental findings indicate that the mean measurement discrepancy of the proposed platinum resistance temperature sensor with radiation shield is 0.0141 K,and the root mean square error is 0.0150 K.
