A Design Of Remote Calibration And Vibration Measurement Platform Based On The Grid Technology And A Research Of Related Critical Technology

Digital Vibration Measurement is a practical application in engineering vibrationmeasurement of computer science, and it is critical for solving vibration measurementindustry’s problem. This paper introduces a Remote Calibration and Vibration MeasurementPlatform based on the grid technology(RCVMP). The platform uses digital technology toefficiently organize process and store the vibration measurement data. The construction of theRCVMP will accelerate the developing of vibration measurement technology, and promotethe evolvement of the whole basting industry.First, this paper introduces the RCVMP, which can standardize the data and circuit ofvibration measurement industry. And it use Computing Grid to process massive vibrationmeasurement data, which will be store in Digital Archive. This paper thoroughly describes thedetail of the platform.Second, this paper introduces a new method of file transfer in computational grid usingP2P technique. Considering the shortage of the original file transfer mechanism of Condor, Iaccelerate the job processing speed of Condor pools using P2P technique. A P2P file systemwas mounted in the platform, working with Condor. Experiments show it cans dramaticallyspeedup the job processing.Finally, this paper introduces an algorithm PPRACO based on a Performance Price RatioModel for Grid Job Scheduling. I have improved the basic ACO algorithm, adding2parameter mand cto control the Performance Price Ratio of the job scheduling plan.Moreover, PPRACO has modified the initial pheromone of ACO, and experiment shows itcan speed up the converge speed of the algorithm.
