An alarm lower limit value and an error reporting lower limit value of the vibration speed can be set through the HMI, and when the vibration speed acquired by the PLC 2 is greater than the alarm lower limit value, the HMI wire releasing end (or wire receiving end) sends out a yellow alarm; when the vibration speed collected by the PLC 2 is larger than the error reporting lower limit value set by the HMI, the PLC controls the speed of the driving wheel motor driver 3, then the driving wheel motor 4 is decelerated, the PLC matches the speed of the paying-off motor driver 5 (or the taking-up motor driver) according to the speed of the driving wheel motor 4, the speed of the paying-off motor 6 (or the taking-up motor) is reduced along with the deceleration, the vibration is reduced along with the deceleration, when the vibration is reduced to be smaller than the error reporting lower limit value, the deceleration is stopped, and the equipment starts to run at a constant speed.
