虚拟仪器的模糊温度测试仪设计

Design of Fuzzy Temperature Measuring Instrument Based on Virtual Instrument

传统温度测试仪器主要由硬件构成,因而成本和规模都比较大,操作也不方便。另外在很多实际问题中,仅仅用精确数值对被测对象进行描述是不够的。针对以上问题,对基于模糊测量原理的虚拟温度测试仪的设计进行了研究,利用虚拟仪器的专用开发工具LabVIEW并结合Matlab进行软件设计。根据不同的测试对象,综合有关专家经验知识,对被测温度进行更高智能的模糊推理,最终实现对测量温度的符号输出。

The traditional measuring instrument of temperature was mainly consisted of hardware, its cost and dimensions were quite big; and the operation was inconvenient. In many practical applications, describing the measured objects only by accurate values were not enough. Aiming at these problems, the design of virtual temperature measuring instrument based on fuzzy measurement principle is researched. With dedicated virtual instrument developing tool LabVIEW, and combining with Matlab, the software is designed. Based on different measured object, integrating related experts＇ experience and knowledge, more intelligent fuzzy inference is conducted to measured object, the symbol output of measured temperature is implemented finally.
