    • A method of determining the rotative position of an industrial roll includes (a) providing a rotating industrial roll having a longitudinal axis, the industrial roll having mounted on one end thereof an accelerometer, the industrial roll further including a plurality of sensors; (b) determining a pre-trigger angular position of the roll based on a first gravity vector provided by the accelerometer; then (c) determining a trigger angular position of the roll based on a second gravity vector provided by the accelerometer, the magnitude of the second gravity vector differing from the magnitude of the first gravity vector by more than the magnitude of a typical noise signal; and (d) gathering data from the sensors after the roll has passed the trigger angular position; and (e) matching data gathered in step (d) with a respective sensor of the plurality of sensors based on the determination of the trigger angular position.

    • A method of determining the angular position of a roll includes: (a) detecting signals generated by an accelerometer attached to an end of a rotating roll; (b) determining whether a signal generated in step (a) has reached a pre-trigger threshold, and repeating step (a) if the signal has not reached the pre-trigger threshold; (c) if the signal is determined in step (b) to have reached the pre-trigger threshold, detecting a subsequent signal generated by the accelerometer; (d) determining whether the signal detected in step (c) has reached a trigger threshold, and repeating step (c) if the signal has not reached the trigger threshold; and (e) if the signal has reached the trigger threshold, establishing the angular position of the roll based on the signal that has reached the trigger threshold.
    • 确定辊的角位置的方法包括:(a)检测由附接到旋转辊的端部的加速度计产生的信号; (b)确定步骤(a)中产生的信号是否已经达到预触发阈值,并且如果信号还没有达到预触发阈值,则重复步骤(a); (c)如果在步骤(b)中确定已经达到预触发阈值的信号,则检测由加速度计产生的后续信号; (d)确定在步骤(c)中检测到的信号是否已经达到触发阈值,并且如果信号尚未达到触发阈值,则重复步骤(c) 和(e)如果信号已经达到触发阈值,则基于已达到触发阈值的信号建立滚动角度位置。
