Beschreibung
Zusammenfassung:	The invention discloses a real-time measurement system and method for a blade tip circle contour of a rotor blade disc of a rotating machine, and the system comprises a to-be-measured blade disc, a sensor, a sensor driving and conditioning module, a blade tip gap measurement module, a blade tip timing signal collection module, a blade number matching module, a key phase frequency division module, and a blade tip circle contour measurement module. The sensor is installed on a casing directly facing a bladed disc to be measured, the sensor is connected with the sensor driving and conditioning module, the sensor driving and conditioning module is connected with the blade tip gap measuring module and the blade tip timing signal acquisition module, the blade tip gap measuring module is connected with the blade number matching module, and the blade number matching module is connected with the blade timing signal acquisition module. The blade tip timing signal acquisition module is connected with the key phase frequ
