MEASUREMENT DATA SYNCHRONIZATION METHOD, TESTING METHOD AND COMPUTER PROGRAM

To provide a measurement data synchronization method in which time-series data output from a plurality of measuring instruments can be accurately synchronized.SOLUTION: A measurement data synchronization method in which time-sequences output from first through fifth measuring instruments are synchronized by a data analysis device comprises: a step ST1 of acquiring first through fifth reference data output from the first through fifth measuring instruments when a reference signal including a stationary interval and a rising interval is simultaneously input into the first through fifth measuring instruments; steps ST3-ST5 of generating data after first through fifth filter processing by performing median filter processing in which median values within predetermined time width are extracted for first through fifth reference data; a step ST6 of calculating first through fifth rising times as rising timing information from each of pieces of data after the first through fifth filter processing; and a step ST7 of synchronizing first through fifth measurement data output from the first through fifth measuring instruments on the basis of the first through fifth rising times.SELECTED DRAWING: Figure 3 【課題】複数の計測器から出力される時系列データを精度良く同期できる計測データ同期方法を提供すること。【解決手段】計測データ同期方法は、第１～第５計測器から出力される時系列をデータ解析装置によって同期する方法であって、定常区間と立ち上がり区間とを含む基準信号を同時に第１～第５計測器へ入力したときに、第１～第５計測器から出力される第１～第５基準データを取得するステップＳＴ１と、第１～第５基準データに対し所定の時間幅内の中央値を抽出するメディアンフィルタ処理を施すことにより、第１～第５フィルタ処理後データを生成するステップＳＴ３～ＳＴ５と、第１～第５フィルタ処理後データの各々から立ち上がりタイミング情報として第１～第５立ち上がり時刻を算出するステップＳＴ６と、第１～第５立ち上がり時刻に基づいて第１～第５計測器から出力される第１～第５計測データを同期するステップＳＴ７と、を備える。【選択図】図３
