Difference can also be that the other of the signal stabilization that one of ordinary skill in the art is understood measure.
In a step 208, controller 116 can determine the second variance of the second duration of signal.Second variance can
Determined with using with first variance identical mode.If for example, first variance is the signal frequency in the first duration
Standard deviation, then second variance is by the standard deviation of the signal frequency in being the second duration.
In step 210, controller 116 can determine disk roller based at least one in first variance and second variance
104 decouple with work materials 102.When disk roller 104 and work materials 102 are decoupled, being received from the signal of sensor 124 may change
Become and become unstable.First variance and/or second variance be signal stabilization measure and be determined for disk roller 104 with
Work materials 102 are decoupled.It is exemplary that Fig. 4 shows that the sensor 124 of machine 100 according to an aspect of the present invention is generated
Signal.In this example, disk roller 104 can be decoupled when the second duration t2 starts with work materials 102.Controller 116
The first duration t1 first variance can be determined and the second duration t2 second variance is determined, to detect disk roller 104
Decoupling.
In one aspect, first variance and second variance can be compared by controller 116, and can in first variance and
Difference between second variance determines that disk roller 104 is decoupled with work materials 102 when exceeding threshold value.As it was previously stated, first variance
It is measuring for signal stabilization in the first duration.First duration can be that disk roller 104 shows normal operating row
For and keep being suitably coupled to duration of work materials 102.When disk roller 104 and work materials 102 are decoupled, signal becomes
Change and the second variance of the second duration likely differs from first variance.Although being likely to occur in course of normal operation
Some of first variance and second variance change, but the difference between first variance and second variance exceedes predetermined threshold and may referred to
Show that disk roller 104 is decoupled with work materials 102.Equally, when the ratio between first variance and second variance exceedes first threshold
When, controller 116 can determine that disk roller 104 is decoupled with work materials 102.
In another aspect, when second variance amplitude exceed threshold value when, controller 116 can determine disk roller 104 with
Work materials 102 are decoupled.Controller 116 can have the predetermined threshold of the stability range corresponding to debulking systems 101.Predetermined threshold
The numerical value of the value above can indicate that disk roller 104 is decoupled with work materials 102.As it was previously stated, second variance can be peak value-peak
Value amplitude, peak-peak amplitude variance, average frequency, average frequency variance etc..When the amplitude of second variance exceedes threshold value,
Controller 116 can determine that disk roller 104 is decoupled with work materials 102.Threshold value is likely to be dependent on the operating parameter of machine 100,
Engine speed, speed change etc., and the operating parameter, such as work materials 102 of Work places material character.
In the step 212, controller 116 can be in response to determining that disk roller 104 and work materials 102 are decoupled and make correction
Action.In some respects, controller 116 can forward alarm to the operator of machine 100.The alarm can indicate disk roller 104
Decoupled with work materials 102.Controller 116 can be into alarm operator useful diagnostic message is provided.For example, alarm
The operation setting of machine 100 when can be decoupling, such as engine speed of machine 100, speed changer are set, disk roller 104 shakes
Dynamic frequency, Oscillation Amplitude of disk roller 104 etc..Receive after alarm, the operator of machine 100 can take appropriate action.
In other side, correction action can be the operation setting for adjusting machine 100.For example, controller 116 can be determined
Change, setting of vibrational system 118 of the power potential of power source 108 etc., will allow disk roller 104 to be re-coupled to work materials
102.Controller 116 can forward instruction to the operator of machine 100, and containing in instruction makes disk roller 104 recover and work materials
The 102 operation setting changes coupled again.Controller 116 can be based on machine 100 operation setting (such as hair of machine 100
Motivation speed, speed changer setting, the vibration frequency of disk roller 104, the Oscillation Amplitude of disk roller 104 etc.) change to determine to set.Example
Such as, controller 116 can forward the Oscillation Amplitude for making disk roller 104 to set the instruction for reducing to the second setting from first.In other sides
Face, controller 116 can be with the operation setting of adjust automatically machine 100, without operator's input.
As used herein, controller 116 can be the device based on processor, and it is calculated by performing from non-transitory
The computer executable instructions that are read in machine computer-readable recording medium are operated.Non-transitory computer-readable medium can be hard disk
Driver, flash drive, RAM, ROM, optical memory, magnetic memory, its combination, or any other machine known in the art
Computer-readable recording medium.Controller 116 can be single assembly or multiple devices.Further, controller 116 can be nonshared control unit or
Person can be real in the existing controller for equally providing one or more of the other function (such as engine or machine speed control)
