Non-electrical signal such as temperature and strain is an important basis for evaluation of the health state of building structure. How to measure and collect non-electricity information in building structure and how to deal with this information is introduced in this paper. Intelligent structure characteristic data analysis and display system is developed by LabVIEW including filtering, spectral analysis, the current data and historical data display. LabVIEW has characteristic of multi-task real-time synchronization operation, guarantee requirements such as real-time, reliability and scalability of the intelligent structural characteristics data processing and display system.
