The upper computer 120 may be configured to receive control parameters of the wind-up roll apparatus input by a user, and send the control parameters to the main line controller 110.
As shown in fig. 1, the main line controller 110 is connected to the deviation rectifying controller through a fieldbus profibus-DP, wherein the main line controller 110 may be selected according to an actual production line, for example, in a cold rolling production line, the main line controller 110 may be a heavy wire controller. The upper computer 120 can be provided with a visual monitoring and alarming system, so that the related information of the deviation correcting roller equipment can be displayed in real time, and meanwhile, the control parameters for controlling the deviation correcting roller equipment, which are input by a user, can also be received.

And the main line controller 110 is configured to determine whether the control parameter is legal, and send the control parameter to the deviation rectifying controller when the control parameter is legal, so that the deviation rectifying controller controls the deviation rectifying roller device to perform a corresponding deviation rectifying operation based on the control parameter.

When the position of the strip steel exceeds 70% of the allowable range (+ -20%), the pressure is automatically increased by 10% given (50 bar); when the position of the strip steel exceeds 80% of the allowable range (+ -20%), the pressure is automatically increased by 20% given (50 bar); when the strip position exceeds 90% of the allowable range (+ -20%), the pressure is automatically raised by 30% given (50 bar).
