Labview虚拟仪器的温度检测系统设计及应用

Abstract With the continuous development of electronic testing technology, testing techniques are moving towards automation, intelligence, digitization, and networking. Digital filters are widely used in various fields as important tools in testing technology. This project focuses on designing a temperature detection system using LabVIEW and its applications. This paper introduces relevant knowledge about LabVIEW and utilizes the software system developed using the virtual instrument development platform- LabVIEW. The system consists of five main modules: data acquisition, display and recording, data playback, data processing, and data analysis. VI is a product that combines computer technology with traditional instrument technology and is an important direction in the development of instruments. LabVIEW is a software development tool based on graphical virtual instruments mainly used in areas such as automatic testing, process control, instrument design, and data analysis. The basic idea is to replace hardware with software as much as possible in instrument design or testing systems, meaning "software is the instrument". It aims to define and design instrument testing functions based on user needs on a general computer platform, essentially utilizing the latest computer technology to achieve and expand the functions of traditional instruments. This paper mainly introduces the application of the virtual instrument interface LabVIEW and designs a digital and control system based on virtual instruments, elaborating on the key aspects of data acquisition and hardware-software design in the system development process. Keywords: LabVIEW, temperature measurement, data acquisition
