Research on Temperature Test System Based on LabVIEW

摘要

As it is difficult to measure the temperature accurately under actually environment, this paper develops a virtual temperature measurement system based on LabVIEW. The system consists of AD590 temperature sensor and virtual instrument, and the properties and structure of AD590 is discussed in this paper. In addition, we do some research on the measurement method, and use soft filter and Normalized method to remove noise and improve the measurement accuracy. The structure and soft system of the virtual instruments system are designed and a high value measurement system is achieved using the resources of the virtual instruments. The experimental results have shown that the system can satisfy the accurate requirement in harsh condition.
