Research on Parallel Processing Method for Ground Penetrating Radar Data in State Detection of Railway Subgrade
摘要
Abstract
In order to improve the processing speed of large amount of ground penetrating radar (GPR)data produced by railway subgrade state detection,shorten the generation cycle of test report,parallel computing technology was introduced to design and construct the parallel processing platform for GPR data analysis.Computer cluster was used to process and analyze GPR data.Dynamic load balance algorithm based on server computing ability was proposed to schedule and distribute the GPR process task submitted by users.Experiments were carried through on the constructed parallel processing platform with the actual GPR data of railway subgrade condition detection.The accuracy,time consumption,parallel speedup and system scalability of the GPR data parallel processing platform were analyzed.Results show that the GPR data processing efficiency of 8-node cluster parallel processing platform is increased by 553% compared with the single version software.The processing time is reduced by more than 50% compared with the GPR data processing method based on Hadoop.关键词
