| description | To provide a concrete compaction management system capable of determining a status of a vibrator without preparing a vibrator capable of sampling at a high frequency.SOLUTION: A concrete compaction management system managing a concrete compaction status by a vibrator comprises a vibration sensor, vibration characteristic calculation means, and status determination means. The vibration sensor can measure a frequency that is less than twice a frequency of the vibrator. The vibration characteristic calculation means calculates a pseudo frequency and a pseudo amplitude based on a pseudo wave form (a wave form in which aliasing is generated) obtained by the vibration sensor. The status determination means determines an operation status or a movement status based on the pseudo frequency and the pseudo amplitude.SELECTED DRAWING: Figure 6
【課題】本願発明の課題は、従来技術が抱える問題を解決することであり、すなわち、高周波数でのサンプリングが可能な振動センサを用意することなく、振動バイブレータの状況を判定することができるコンクリート締固め管理システムを提供することにある。【解決手段】本願発明のコンクリート締固め管理システムは、振動バイブレータによるコンクリートの締固め状況を管理するシステムであって振動センサと振動特性算出手段、状況判定手段を備えたものである。振動センサは、測定可能な周波数が振動バイブレータの周波数の２倍未満である。振動特性算出手段は、振動センサによって得られる疑似波形（エイリアシングが生じた波形）に基づいて疑似周波数と疑似振幅を算出する。状況判定手段は、疑似周波数や疑似振幅に基づいて作動状況あるいは移設状況と判定する。【選択図】図６ |
