A method of monitoring a device for monitoring the floating of a profiled pull roll on-line according to claim 1, characterized in that: the infrared radiation emitted by the on-line monitoring infrared detector (4) irradiates to the fixed position of the floating end traction roller (3) and is reflected by the position and then fed back to the receiving device of the on-line monitoring infrared detector (4), the on-line monitoring infrared detector (4) can change a distance signal received by the on-line monitoring infrared detector (4) due to the change of the position offset of the floating end traction roller (3), the distance signal is transmitted to the data processing terminal computer (5), the floating variation of the floating end traction roller (3) is displayed by the data processing terminal computer (5), the floating amount of the floating end traction roller (3) is obtained by reducing the minimum value from the maximum value of the distance in a circle of the roller body running measured by the on-line monitoring infrared detector (4), when the floating end traction roller (3) uniformly rotates, the position of the floating end traction roller (3) on a sliding table can change along with the downward running of the traction glass, the variation range is less than one millimeter, when the floating end traction roller (3) rotates unevenly, the floating end traction roller (3) can move transversely on the sliding platform by more than one millimeter, when the variation amount with larger range is monitored, the rotation unevenness of the floating end traction roller (3) is monitored, relevant measures are taken in time to carry out countermeasures, the product loss is reduced, an online monitoring infrared detector (4) is installed on one side of the floating end traction roller (3), and the distance variation of the floating end traction roller (3) caused by the rotation unevenness is detected in real time through the online monitoring infrared detector (4), so that the floating amount and the rotation state of the floating end traction roller (3) can be measured online in real time, and the method for stabilizing the production and the quality of the glass plate is achieved.
