Research On Data Acquisition And Fusion Of Fiber Optic Multi-sensors System

It is a development tendency for a sensing system to measure a physical parameter by using multi-sensor in order to improve the systematic stability and accuracy. For this purpose, this issues related with the configuration and data processing of the multi-sensor system should be in-depth developed and investigated. The simplest way is to receive, save and calculate large amount of data by using a computer.Based on the research of the theories about systematic composing, data fusion of multi-sensor system and the interface between multi-sensor system and the software, a practical scheme for acquisition and fusion of the data from multi-sensor with software has been proposed and demonstrated in this paper. The description of hardware setup and the software flow chart and functions of the multi-sensor system has been given in chapter 4 in detail. Experimentally, fiber-optic multi-temperature-sensors have been used and configured a multi-data acquisition and fusion system. The software of the data fusion technique has been tested. Comparing with data directly given by the fiber optic sensors, more accuracy results have been achieved after the data fusion processing.The problem and shortcomings we encountered during this research work are also discussed. The improvement methods both in theoretical and experimental are pointed out for the further study.
