PROCESSING OF THE OBSERVATION RESULTS FOR NON-ELECTRICAL MEASUREMENT DEVICES BY RUNGE-KUTTA METHOD

Abstract

Based on analyzing the Runge-Kutta approximation method, the author proposes a method of looping the values of non-electrical measurement devices to improve the accuracy of the processing of observational results. The algorithm was built to calculate the measurement results with digital data from the analog-digital converter, which was iteratively computated according to the Runge-Kutta method of order 4, thereby detecting the error and correcting the displayed value.The efficiency of reducing errors of the algorithm which was verified by examining a test pressure measurement device with direct result calculation modes to compare with the result processing mode by the Runge-Kutta method confirms the correctness of the proposed solution.
