Abstract: An early warning system includes functional equipment, a first monitor unit, a second monitor unit, a calculation unit and a warning unit. The functional equipment is used to perform a functional operation. The first monitor unit is used to monitor the functional equipment so as to obtain a set of first data during a first period. The second monitor unit is used to monitor the functional equipment to obtain a set of second data during the first period. The calculation unit is used to receive the set of first data and the set of second data, obtain a correlation coefficient according to the set of first data and the set of second data, and compare the correlation coefficient with a threshold value. The warning unit is linked to the calculation unit and used to send a warning signal when at least the correlation coefficient reaches the threshold value.

Abstract: A set of sensors is disposed beside a cylinder to collect a first set of temperature points. The first set of temperature points is updated and distributed on a coordinate plane corresponding to a length and rotation degrees of the cylinder. The coordinate plane is segmented along a horizontal axis with a fixed length to define a rectangular area, and a second set of temperature points is distributed on the rectangular area. The second set of temperature points is a subset of the first set of temperature points. On the rectangular area, the second set of temperature points is clustered into n sets of temperature points using a k means algorithm. A notification signal is sent according to an xth set of temperature points of the n sets of temperature points. The xth set of temperature points has a highest mean temperature among the n sets of temperature points.
