Research and experiment of rope measurement method for subsea pipeline based on uncertainty analysis

Abstract

In order to solve the problem of assessment of the measurement of the pipe bit posture, this paper first analyzes the measurement rope line theory, and then analyzes the propagation factor of different positioning methods, and finally proposes a different positioning. The mode of measurement device is evaluated in the mode of measurement. This paper establishes a measurement model based on different positioning mode, based on robot theory and transition matrix algorithm, solving the relative position position information between two pipes. Finally, according to the resulting measurement model, the propagation coefficients in uncertainty theory are analyzed, and the foundation is laid for uncertainty analysis. Through the land experiment, the applicability and analysis accuracy of this paper is verified for the applicability and analysis of different cord measuring devices.
