Designing of temperature and thermal displacement measurement system in machine tools

摘要

This paper describes the multi-sensor of the data acquisition and signal analyzing based on ihe development of virtual instrument. It sets up a virtual instrumentation with the function of data acquisition and signal analysis, based on computer, temperature sensor, displacement sensor, PCI data acquisition card, and software of LabVIEW8.5 .The data acquisition, preprocessing, displaying, storage and data playback? are integrated in this platform, forming an easy-to-use temnerature and thermal error detection system.
