Beschreibung
Zusammenfassung:	The present invention comprises a non-contact-type vibration sensor for collecting vibration data in a non-contact manner at a long distance in order to diagnose a CNC equipment state and a CNC machining process state. Vibration characteristics include frequency (hz) and amplitude, and the present invention detects frequency through an acoustic sensor, and detects amplitude through a current sensor for detecting a load generated by an object. Whenever the two characteristic values are generated in the same time, these characteristic values are merged and used as vibration characteristics of the same time period. La présente invention concerne un capteur de vibration de type sans contact pour collecter des données de vibration sans contact à une longue distance afin de diagnostiquer un état d'équipement CNC et un état de processus d'usinage CNC. Les caractéristiques de vibration comprennent la fréquence (hz) et l'amplitude, et la présente invention permet de détecter la fréquence par un capteur acoustique, et de détecter l'amplitude par un capteur de courant pour détecter une charge générée par un objet. Chaque fois que les deux valeurs de caractéristique sont générées en même temps, ces valeurs de caractéristique sont fusionnées et utilisées en tant que caractéristiques de vibration de la même période de temps. 본 발명은 CNC장비 상태 진단 및 CNC가공 공정 상태 진단을 위해서 원거리 비접촉식 방식으로 진동 데이터를 수집하기 위한 비접촉식 진동센서를 포함하는 것이다. 진동특성의 구성은 진동수(hz)와 진동크기(amplitude)인데, 본 발명은 음향센서를 통해서 진동수를 검출하고 대상물에서 발생하는 부하를 검출하는 전류센서를 통해서 진동크기를 검출한다. 상기 2개의 특성값이 동일시간에 발생할 때마다 이들을 병합하여 동일시간대의 진동 특성으로 사용하게 된다.
