Research of the distributed multi-rate frame synchronization data reconstruct based on spline
Wenjie Wu, Dagui Huang, Zheng Dong · 2009
In distributed measurement and control network system with different sampling modes and sampling rates, each channel varies from sampling period for data acquisition. How to realize synchronous data reconstruct in different sampling modes, and to realize the treatment in site and application of state monitoring and fault diagnosis are important steps of temporal and spatial alignment development in multi-sensor data fusion. A frame scan synchronization method through directional filtering and data fusion is presented in this paper. It applies synchronous reconstruction technology based on spline interpolation for various sampling modes or different starting time of sampling data. This method can transform the data with same frame rate and realize synchronous of sampling rates. The simulation experiments manifest that the method is valid and accurate.
