摘　　要：本文介绍了一种基于径向基(RBF)神经网络的镍铬-镍硅热电偶特性无差优化模型的建立过程、LabVIEW调用MAT-LAB的方法和热电偶温度虚拟测量的实现过程。结果表明提出的模型算法简单、精度高、稳定性好、对其它传感器建模有借鉴作用。虚拟测量实现过程简单,数据可由计算机直接读取和编辑,节省费用,能应用于多点温度测量和组建传感器网络虚拟仪器系统。In this paper, the process of building an error-free model of Ni-Cr Ni-Si thermocouple characteristic using radial basis function （RBF） neural network, method of LabVIEW calling MATLAB and virtual realization of temperature measurement are presented. The results indicate that the model presented is simple in algorithm, accurate, steady and is used for reference to building model of other sensors, The virtual realization is easy and inexpensive since data can be accessed or edited on computer, and also applied to multiple-spot temperature detection or establishing a sensor network VI system.
