A process of generating the reference mask waveform for each sensor signal by the mask waveform generating unit 250 will be described below.

First, when the first sensing signal 300 or 320 is collected as shown in FIG. 4A for a predetermined time, the mask waveform generating unit 250 generates a mask waveform for the first sensing signal 300 or 320 of FIG. A reference mask waveform 310 in the form of a sinusoidal wave as shown in FIG. 4B or a reference mask waveform 330 in the form of a pulse as shown in FIG. 4C can be generated based on values, minimum values, . At this time, the mask waveform generator 250 may generate a sinusoidal reference mask waveform 310 or a pulse reference mask waveform 330 in consideration of a predetermined error range.

As described above, the mask waveform generating section 250 generates reference waveforms corresponding to the horizontal and x-axis bending states, the reference mask waveform corresponding to the vibration state during rotation, and the parallel state and bend degree of the roller 200 And store it in the memory 264.

Specifically, the defect state determiner 260 divides the severity of the roller 200 into five levels using the degree of defect for each state. If the severity is greater than or equal to 3, the defect state determiner 260 determines that the defect state is large, To the alarm generating unit 262. [

5 is a flowchart illustrating a process of analyzing the state of the roller by the roller defect detection apparatus 100 according to the embodiment of the present invention.

5, the roller defect detection apparatus 100 detects a first sensing signal, a second sensing signal, and a third sensing signal sensed by the sensor unit 230 by using the signal collecting unit 240 for a predetermined period of time, The sensing signal is collected (S400). Here, the preset time can be set based on the input of the manager.

Then, the roller defect detection apparatus 100 generates a reference mask waveform using the mask waveform generator 250, which will be described below.

First, the mask waveform generator 250 extracts a period, a maximum value, a minimum value, and the like through analysis of each sensing signal collected by the signal collector 240, and outputs the extracted period, maximum value, minimum value, (Step S402). Then, the mask waveform generator 250 extracts the averaged data through statistical analysis on the waveform for each cycle, and generates a representative waveform corresponding to each sensing signal based on the extracted averaging data (S404).

Then, the mask waveform generator 250 generates a reference mask waveform corresponding to each sensing signal by patterning the representative waveform through period, amplitude, and user band setting (S406).

The reference mask waveform for the first, second, and third sensing signals is generated through the steps S402 to S406 as described above.

Then, the defect state determination unit 260 of the roller defect detection apparatus 100 compares the waveform of each sensing signal collected in real time through the signal collecting unit 240 and each reference mask waveform corresponding thereto, , Mask invasion degree, period match rate, and pattern match rate (S408, S410).

Then, the defect state determination unit 260 determines whether the defect is defective by determining the state of the roller based on the extracted value, that is, the horizontal state, the degree of bending in the X-axis direction, the parallel state, the degree of bending, ).

As a result of the determination in step S412, if a defect is found, the defect state determiner 260 notifies the alarm generator 262 of an alarm message (S414).

On the other hand, if it is determined in step S412 that the defect is not a defect, the defect state determination unit 260 stores the data related to each sensing signal in the memory 264 (S416), and then returns to step S408 to perform subsequent steps.

In the embodiment of the present invention described above, the reference mask waveform is formed for each sensing signal to analyze the defect state of the roller 200. However, the representative reference mask waveform may be formed by integrating each sensing signal, The defect state of the roller 200 may be analyzed. In this case, the coupled state determination unit 260 combines each sensing signal collected by the signal collecting unit 240, and then compares the combined sensing signal with the representative reference mask waveform to determine a cycle coincidence rate, a mask invasion degree, And the area matching ratio may be extracted to determine whether the roller 200 is defective or not.
