Flow Design Bureau (FDB) rely on LabVIEW software solutions and hardware integration for managing of large data quantities. This presentation focuses on two applications: 1. Continuous acquisition of data from a distributed monitoring system with analysis on demand, and 2. Continuous and real time acquisition and analysis of sensor data in an instrument application.
A hydropower plant in Norway is equipped with 5 separate measurement locations distributed over several kilometers. With up to 10 sensors acquired at a high sampling rate at each location, a huge number of data is to be stored, but also to have a correct absolute time-stamp. From stored data, users can order statistical analysis on demand. This presentation highlights solutions related to data transfer and storage, time- synchronization and data retrieval and analysis. The latter also includes a brief introduction to Kalman filtering techniques applied in order to improve the measurement accuracy of specific parameters of interest.
One development within FDB is a cavitation intensity quantification system. The analysis resulting in cavitation intensity bases itself on 30-second samples holding about 3M values each. During the analysis, a number of memory demanding functions launches and completes. This paper reports the real-time solution meeting this challenge.
