Development of Strain Measurement System Based on Virtual Instrument Technology

Abstract:

Based on LabVIEW and CompactRIO platform, a strain measurement system was developed for structure monitoring. The design and achieve method of the system is introduced in detailed. The module of NI 9235 is used to realize the multi-channel signal acquisition at the same time. Data processing and storage online is supported. At last, a test is hold to verify the validity of the system. Comparing with traditional strain measurement system, the system proposed in the paper is stable and reliable. And it is easy to carry, simple operation, performance, high efficiency and good expansibility. The new system with those advantages can adapt to all kinds of complicated and special working environment. It is totally possible that virtual instrument replace the traditional system complete. The new system is worth to promote in application.
