The class that makes preparations for sowing is more and situation is complicated, and the past foundation for causing to lack theory and reality less to the research of equipment alarm thresholding.
In addition, alarm threshold in the mechanism cannot dynamic monitoring, alarming in real time, mainly due to when alarm threshold is constant, and work as

Monitoring effect.
Fig. 2 shows the flow chart of alarm threshold setting method 200 according to an embodiment of the invention, suitable for current
The alarm door limit value for monitoring the characteristic index of unit is set, and can be performed in computing device, such as in computing device 100
It performs.As shown in Fig. 2, this method starts from step S220.
In step S220, the amplitude of characteristic index and the incidence relation of alarm door limit value are previously generated.From the incidence relation
In can know the alarm door limit value that the index feature should be set under different amplitudes, specific generation method will be
It is hereinafter described, wouldn't repeat here.In general, characteristic index can be commonly used in the operation of the mechanical equipments such as rotating speed, acceleration, amplitude
Index parameter, for any of which characteristic index it is executable according to the present invention in alarm threshold setting method, to realize
Equipment condition monitoring purpose.In practical operation, the alarm condition of monitoring many indexes can be chosen, and integrates this many indexes
Situation determines whether to carry out maintenance；One of which index state, the invention is not limited in this regard can certainly only be monitored.
Then, in step S240, the current amplitude of the characteristic index of current monitor unit is obtained, and according to incidence relation
Determine the alarm door limit value that this feature index should be set under current amplitude.It is, the index feature i of current monitor unit
Alarm threshold be current amplification level by same type with the horizontal and current unit of the average amplitude of the index i of an operating mode group of planes
It codetermines.Afterwards, so that it may current alarm threshold be set according to the alarm threshold that the institute should set.
According to one embodiment of present invention, the current amplitude of the characteristic index of current monitor unit is suitable for according to lower section
Method determines：The recent amplitude data of current monitor unit this feature index in recent predetermined period is obtained, and from the recent width
K maximum amplitude before being chosen in Value Data, and using the average value of the preceding k maximum amplitude as the current width of current monitor unit
Value.Predetermined period can be in recent one week, and k can be not limited to this certainly with value 4, and the present invention is not specifically limited this.
For example, all tachometer values in nearly one week of current unit can be obtained, and take average value the working as rotating speed of preceding 4 maximums
Preceding amplitude.Certainly, the calculating of the current amplitude of unit is not unique, and the instantaneous amplitude that can also use alarm point is current as this
Amplitude substitutes into follow-up calculating, and the present invention is not restricted the selection mode of current amplitude.
Further, after getting recent amplitude data, can also pretreatment operation first be carried out to it, i.e., from the recent amplitude
Data, the data of fluctuation of operating conditions period and the error signal data caused by sensor abnormality of period are shut down in removal in data.
In general, shutting down the period is regarded as the period that generating unit speed is less than preset rotation speed threshold value；And for being fitted without speed probe
Unit, shut down the period be believed that the small Mr. Yu of vibration acceleration amplitude preset shut down thresholding when stage.According to one embodiment,
Preset rotation speed threshold value can be 50 revs/min, and generating unit speed is then believed that shutdown less than the numerical value；For middle-size and small-size equipment, preset
2m/s can be set to by shutting down thresholding2, vibration acceleration amplitude is less than the thresholding it is also contemplated that shutdown.Certainly, which simply shows
Example property explanation, may be set to be other numerical value, the invention is not limited in this regard.For fluctuation of operating conditions, technique amount can be passed through
The data of the Information Filtrations fluctuation of operating conditions period such as parameter make it be not involved in thresholding and calculate and alarm.During common fluctuation of operating conditions
Section for example can be pressure change period, flow change period etc..Error signal data are mainly since sensor abnormality causes
Excessive gathered data, it is necessary to remove it.
According to another embodiment of the invention, current monitor unit can usually be obtained when occurring under following either case
Characteristic index current amplitude, and the alarm that this feature index should be set under current amplitude is determined according to the incidence relation
Threshold value：
1) when the unit includes monitoring for the first time, need to be laid with initial threshold, i.e. thresholding initial setting up at this time；
2) unit amplitude of characteristic index among monitoring operation is more than the alarming value set, therefore triggering alarm needs
New thresholding is recalculated to monitor further deterioration, i.e., thresholding adjusts setting after alarm is transfinited；
3), it is necessary to be judged whether according to its current amplitude when the unit even running predetermined period (such as one week) is not alarmed
It needs to lower thresholding, if necessary to lower, then the referred to as readjustment of thresholding.
For first two situation, the alarm threshold setting method in all follow procedures S240 gets current amplitude, really
Determine the corresponding theoretical alarm door limit value of the amplitude, and the theory alarm door limit value is put into and is applied.It, will for the first situation
The theory alarm door limit value is set to initial threshold；For the second situation, then threshold value is adjusted to the theory alarm threshold
Value.And for the third situation, usual failure unit amplitude after maintenance can be fallen after rise.At this moment if adjusting thresholding not in time,
It may be failed to report when unit exception occurs again, therefore need to limit on the door at regular intervals to recalculate once and (write from memory
Think one week) to carry out the readjustment of thresholding.
According to another embodiment of the invention, alarm door limit value can also be adjusted back according to following methods：If work as
Preceding monitoring unit is not alarmed always in scheduled time slot, then obtains the new current amplitude of the current monitoring equipment group；It is closed according to association
System determines the new alarm door limit value corresponding to the new current amplitude；And new alarm door limit value and old alarm door limit value are asked into business,
If its ratio is less than predetermined threshold, new alarm door limit value will be adjusted under threshold value, it is on the contrary then maintain old alarm door limit value.Here
Old alarm door limit value be alarm door limit value when not carrying out callback operation.Wherein, predetermined threshold can be 0.8, certainly
It could be provided as other numerical value, the invention is not limited in this regard.In addition, the acquisition methods of new current amplitude can be according to hereinbefore
Current amplitude acquisition methods, as obtained the recent amplitude data in the even running period, and selected from the recent amplitude data
The average value of k maximum amplitude is as new current amplitude before taking；Alternatively, the instantaneous amplitude of alarm point can also be used new as this
Current amplitude substitutes into follow-up calculating.It is equally possible that k before being carried out again after pretreatment operation is first carried out to the recent amplitude
The selection of maximum amplitude.
The mechanism periodically adjusted back ensure that unit after maintenance and abnormal disappearance, and thresholding can adjust back in time, avoid
Thresholding due to equipment fault before extended stationary periods in a high position.And just may be used when being less than 0.8 times of old thresholding the present invention claims new thresholding
With readjustment, it is on the one hand to prevent because the fuctuation within a narrow range of amplitude causes the frequent change of thresholding；On the other hand, unit is slow
Slow deterioration, amplitude are also in slow lifting, and thresholding is adjusted if as frequent as amplitude constantly synchronously rises, then can be never
It alarms and causes to fail to report.In addition, after it partly can also trigger readjustment, such as equipment shutdown for a long time in special circumstances, a start
Operating should just judge whether to need to adjust back.Alternatively, alarm is since suspicious data causes (doubtful error signal or fluctuation of operating conditions
Signal) and non-genuine deterioration causes, and at this moment needs to detect whether to need to adjust back after shorter time interval (such as one day).Here
Readjustment process can equally take the above method, that is, obtain the new current amplitude of unit, determine corresponding to the new current amplitude
New alarm door limit value, to determine whether to carry out readjustment setting after the new alarm door limit value and old alarm door limit value are compared.
Fig. 3 shows the flow chart of incidence relation generation method 300 according to an embodiment of the invention, suitable for calculating
It performs in equipment, is such as performed in computing device 100.As shown in figure 3, this method starts from step S320.
In step S320, the history amplitude data with the index feature of a current monitor unit same type group of planes is obtained.It should
Work as understanding, equally can first take history amplitude data the pretreatment operation in above-mentioned recent amplitude data, it is no longer superfluous here
It states.Further, history amplitude data can also be defined to the history width with current monitor unit same type with an operating mode group of planes
Value Data.
Then, in step S340, each unit of a same type group of planes is in multiple reference frames from history amplitude data statistics
Growth amplitude when being deteriorated under value.
Then, in step S360, determine that this refers to according to the multiple reference amplitudes and its corresponding growth amplitude that are counted
The alarm door limit value that mark feature should be set under the plurality of reference amplitude.Here, when the history case data for having many units
When, it is possible to amplitude excursion when same type units deteriorate under different amplitudes is counted, is according to the excursion
Corresponding threshold value is can determine, for monitoring exception.
Specifically, if m platform units are shared in a same type group of planes, wherein there are n (m >=n) platform units in same reference amplitude Ai
Under deteriorate, there is the n platforms unit n to increase amplitude, then reference amplitude A at this timeiThe alarm door limit value that should be set as
The average value of this n growth amplitude.If for example, there is a same type group of planes to share 100 units, wherein there are 10 units in amplitude
5m/s2When deteriorated, then 5m/s2It can be included as a reference amplitude in statistics, and count this 10 units respectively and exist
Amplitude (increasing amplitude) during deterioration obtains 10 growth amplitudes.If this 10 increase amplitude in 7-9m/s2Between become
Change, then can use this its ensemble average value (such as 8m/s2) as with reference to amplitude 5m/s2Corresponding alarm door limit value.And if separately have 10
Platform unit is in amplitude 20m/s2When deteriorated, then equally can be by 20m/s2It is included as a reference amplitude in statistics.This
Sample can be directed to the current monitoring equipment group and obtain multiple reference amplitudes and its corresponding alarm door limit value.
It should be appreciated that all amplitudes when can m platform units be deteriorated will thus have all as with reference to amplitude
The growth amplitude of the unit of same reference amplitude is counted, to obtain the alarm door limit value corresponding to the reference amplitude.When
All amplitudes (referred to as deterioration amplitude) when deteriorating can also so be screened, such as only screening quantity meets predetermined ratio
Deterioration amplitude be used as with reference to amplitude.Predetermined ratio can be 5%, be certainly not limited to this.If such as there is the deterioration of 100 units
Amplitude data when then at least 5 units deteriorate under same amplitude, just using the amplitude as with reference to amplitude, is united at this time
The growth amplitude for counting this 5 units is averaged, you can obtains the alarm door limit value that the reference amplitude should be set.In addition, when number
During according to measuring more, for simplicity, can also a selected part deterioration amplitude be used as with reference to amplitude.
For example, it can only choose the deterioration amplitude of quantity accounting several former (first 9)；It can also be by all deterioration amplitude systems
Meter out after by deterioration section select it is wherein several most representative, ensure it is each deterioration the representational amplitude in section
Data.For the former, if occurring 50 deterioration amplitudes in 100 units altogether, the deterioration of preceding 9 occurrence numbers can be chosen
Amplitude is used as with reference to amplitude.For the latter, the regularity of distribution of each deterioration amplitude is first substantially counted, and this multiple deterioration amplitude is drawn
It is divided into multiple sections, chooses most representative several amplitudes in each section afterwards and be used as with reference to amplitude.If some
Unit is all in numerical value 1-10m/s2Between deteriorate, wherein 4m/s2What is deteriorated is most, then in 1-10m/s2Deterioration section in can be with
Choose 4m/s2As a representative reference amplitude, naturally it is also possible to take several reference amplitudes by ranking multiselect.Similarly,
Several most representational deterioration amplitudes are selected in other sections successively to be used as with reference to amplitude.
Table 1 shows the content example of a reference amplitude to monitoring unit and corresponding alarm door limit value, wherein setting
9 reference amplitudes have been put, and have counted this corresponding alarm door limit value of 9 reference amplitudes respectively.Table 2 shows petrochemical industry intermediate item
Rotating speed>The reference amplitude of the acceleration total value of the motor of 900RPM-pump configuration unit and its corresponding alarm door limit value.
Table 1
| Reference amplitude | A1 | A2 | A3 | A4 | A5 | A6 | A7 | A8 | A9 |
| Alarm door limit value | B1 | B2 | B3 | B4 | B5 | B6 | B7 | B8 | B9 |

| Alarm door limit value | 0.5 | 3 | 4 | 6 | 8 | 14 | 25 | 58 | 10008 |
Then, in step S380, according to multiple reference amplitudes and its corresponding alarm door limit value, this feature index is generated
Amplitude and alarm door limit value incidence relation.
According to one embodiment of present invention, incidence relation can use incidence relation formula Bx=Bi+(Ax-Ai)/(Ai+1-Ai)*
(Bi+1-Bi) represent, wherein, AxIt is characterized the amplitude of index, BxFor in amplitude AxThe lower alarm door limit value that should be set, AiAnd Ai+1
In respectively the multiple reference amplitude with AxTwo adjacent reference amplitudes of left and right, BiAnd Bi+1Respectively AiAnd Ai+1It is corresponding
Alarm door limit value.In the present invention, AxThe current amplitude of typically acquired current monitor unit or need readjustment when
New current amplitude, by AxIt is updated in above-mentioned formula, you can obtain the alarm that the index feature should be set under current amplitude
Threshold value.
According to one embodiment of present invention, incidence relation can be represented with threshold curve, and wherein threshold curve is suitable for logical
It crosses and the lower alarm door limit value that should be set of multiple reference amplitudes with line segment is connected and is generated.Fig. 4 is shown according in table 2
The example of threshold curve that is generated of numerical value.The lines being located above in Fig. 4 are the lines successively of 9 threshold values, under being located at
The line successively of lines then 9 reference amplitudes of side, so as to obtain threshold curve.When needing to set alarm threshold, as long as
It first checks the current amplitude of unit, determines its location point in lower curve, then search the location point institute in curve on the top
Corresponding point is the lower alarm door limit value that should be set of the current amplitude.
Fig. 5 shows the dynamic effect schematic diagram of thresholding adjustment according to an embodiment of the invention.As can be seen that index
Amplitude rapid increase near in March, 2016, the frequent trigger threshold alarm within the period.Alarm threshold also therefore carried out by
Step up-regulation, to guarantee constantly to capture the state that unit persistently deteriorates.Afterwards, field personnel improves equipment profit
It is sliding so that vibration acceleration amplitude is fallen after rise.Thresholding is also followed by automatic fall-back after a period of time, thus occurs below small
Amplitude fluctuations can also be caught in well, so as to strengthen the monitoring to unit.
Technique according to the invention scheme realizes the automatic of criteria thresholds in vibration monitoring field and is laid with and adjusts automatically
