The technical problem of the present invention is to sense abrupt vibration sufficiently ahead of the occurrence time of abrupt vibration. An early sign detection device includes a plurality of sensors; a data acquisition unit configured to acquire time series variation data of a physical amount from each of the plurality of sensors; a computation unit configured to compute an occurrence probability of a vibration mode involved in a sudden variant vibration of a detection subject from an amplitude or a phase of the time series variation data of the physical amount at each of the plurality of positions; and a detection unit configured to detect an early sign of the sudden variant vibration on the basis of the occurrence probability of the vibration mode S. The plurality of sensors are respectively disposed at a plurality of positions of the detection subject and are each configured to measure the physical amount at a corresponding position of the plurality of positions. 本发明的技术问题是比突变振动的发生时间充分提前地感测突变振动。预兆感测装置具备：
