摘 要 虚拟实验与虚拟实验室是随着计算机技术、虚拟仪器技术的发展而出现的。 作为一种全新的实验方法，虚拟实验不受时间、空间等条件的限制，具有传统 实验方法不可比拟的优越性。传感器是测量控制系统的首要环节，对测试系统 起着至关重要的作用。传感器种类繁多、涉及知识面广。对传感器可以从传感 器的工作原理、结构组成、调理电路及特性分析几个方面来把握。为此，本文 采用虚拟仪器技术对传感器虚拟实验研究进行了探索。 首先，本文对虚拟实验及虚拟实验平台的概念及实现技术进行论述。根据传 感器实验的具体情况，选择LabVIEW虚拟仪器为传感器虚拟实验平台的主要开发 工具。接着对总体的设计流程进行论述并设计实现传感器虚拟实验，实现传感器 实验的数据采集及特性分析。最后对以后传感器虚拟实验平台的发展做了展望。 关键词：传感器；虚拟实验平台；虚拟仪器；LabVIEW I Abstract The Virtual Experiment and Virtual Laboratory appear with the development of computer technique and Virtual Instrument technique.As a new experiment method,the Virtual Experiment is out of the limits of time and space,and it has superiority that the Traditional Experiment doesnt have.The sensor which plays an important role is the initial link of measurement and control system.The sensors category is numerous and the knowledge involved is wide.We can understand sensor from the work principle,the structure and the constitution,the adjusting circuit and the characteristic analysis.The thesis studies the Sensor Virtual Experiment and Virtual Laboratory with Virtual Instrument technique. Firstly,using LabVIEW,the sensor virtual experiment can collect and analyze data. So I think the LabVIEW virtual instrument development tool is the main choice of sensor virtual experiment platforms. Secondly the overall design process is determined,anddesign and implementation the sensors virtual experiment.Then implementation sensors virtual experiment data acquisition and analysis of the sensors
