Embodiment 1
The present embodiment provides the associated diagnosis control method of air compressor air storage tank pressure data is based on, this method is applied to each
In kind automatic control system, it can be gone out according to the actual change situation of process data in the equipment that some generates process data
It when now abnormal, reported an error rather than is shut down to air compressor machine, avoid influence caused by whole shut down.
Specifically, as shown in Figure 1, the method includes data correlation establishment step S1 and data association process step
S2.The data correlation establishment step includes following sub-step:
S11: establishing the incidence relation of data, and the data include a control data and at least one non-control；
The control data are gas tank pressure, and the non-control is other data associated with the gas tank pressure, including gas
In pressure tank rise/fall speed, air compressor machine throughput, compressor operation/dwell time, motor current and motor voltage
One or more.
Wherein, data are controlled and non-control is data relevant to air compressor machine, control data (the i.e. gas tank
Pressure) be that the main monitoring of air compressor machine controls data and control foundation, the non-control (i.e. the rising of gas tank pressure/under
One of reduction of speed degree, air compressor machine throughput, compressor operation/dwell time, motor current and motor voltage are more
Kind) it is other data associated with the control data.
And preferably, in the present embodiment, the non-control further includes that the gas tank pressure data is caused to become
Other data changed and gas tank pressure data variation lead to other changed data of other data.
In addition, the data include the pace of change of process data detected value itself and/or process data detected value.
In the present embodiment, control object is air compressor machine, and the control data are gas tank pressure.And its corresponding non-control
Data processed include gas tank pressure rise/fall speed, air compressor machine throughput, compressor operation/dwell time, motor current and
One or more of motor voltage.
S12: the limit section of non-control of the setting control data in specified value.
Wherein, in the present embodiment, following three kinds of situations are specifically included to the step:
(1) by the artificially various operating conditions of setting air compressor machine under normal operation, the pneumatics under various operating conditions is obtained
The limit section of the data (gas tank pressure and associated non-control) of machine, i.e., the described air compressor machine occur in normal operation
The maximum value and minimum value of non-control are corresponded to when each value of gas tank pressure data when various operating conditions；Or
(2) limit section is set according to the data detected after the air compressor machine normal operation input, i.e., described in acquisition
Air compressor machine gas tank pressure data in normal course of operation corresponds to the maximum value and minimum of non-control in each value
Value；Or
(3) by way of software emulation, simulation air compressor machine in normal operation gas tank pressure data in each value
When correspond to the maximum value and minimum value of non-control, the setting in Lai Jinhang limit section.
I.e. the setting in limit section can be according to artificial setting operating condition to obtain, can also be according to the actual conditions of operation
It is configured, can also be realized by way of simulation.
Limiting value set in addition can be actual numerical value, the certain percentage for the actual numerical value being also possible to.
That is, in the present embodiment, need to establish gas tank pressure in each gas tank pressure value, respectively with gas tank pressure
It is a kind of in power rise/fall speed, air compressor machine throughput, compressor operation/dwell time, motor current and motor voltage
Or a variety of limit section.
After completing data correlation establishment step S1, data correlation processing step S2 is come into effect.Specifically, the number
Include following sub-step according to association process step:
S2: the data acquired in real time are judged, comprising:
Value is corresponded to when the numerical value of some key non-control and/or multiple non-control does not fall within gas tank pressure
The limit section when, then it is assumed that related relevance rule is not met between gas tank pressure non-control associated with it, to gas
Pressure tank data diagnosis reports an error.
Wherein, in the present embodiment, as gas tank pressure is in each gas tank pressure value, respectively by collected gas tank
It is needed in pressure rise/fall speed, air compressor machine throughput, compressor operation/dwell time, motor current and motor voltage
The data wanted are compared with corresponding limit section, if wherein N number of go beyond the limit of section, are reported to control data
It is wrong.
In general, in data establishment step S1, when real-time collected process data is under normal circumstances
When, the non-control in process data is certain in the limit section for falling into corresponding control data.
If in certain group associated data at some time point, some key non-control and/or multiple non-controlling
When the numerical value of data does not fall within corresponding gas tank pressure data and corresponds to the limit section of value, then it is assumed that gas tank pressure data and Qi Guan
Correlation rule is not met between the non-control of connection, then judges that gas tank pressure data is invalid (i.e. generation control at this time
The sensing equipment or transmission route of data go wrong), and diagnosis is carried out to gas tank pressure data and is reported an error.
That is, the sensor for acquiring gas tank pressure at this time probably goes out if there is the situation in above-mentioned steps
Existing problem, needs to report an error to the gas tank pressure sensor at this time.
In addition, in the preferred embodiment of the present embodiment, when some key non-control and/or multiple non-controlling numbers
According to numerical value do not fall within gas tank pressure and correspond to the limit section of value when, judge that the gas tank pressure data malfunctions, be not intended as pair
The control foundation of air compressor air storage tank pressure is answered, and is carried out using non-control as control according to air compressor air storage tank pressure
Faults-tolerant control is that foundation indirectly controls air compressor air storage tank pressure with non-control.
Specifically, in the preferred embodiment at this, described " must not be corresponding empty using the gas tank pressure data as control
The foundation of press reservoir pressure, using non-control as the foundation for controlling corresponding air compressor air storage tank pressure ", including two kinds
Mode is controlled:
(1) threshold value is respectively set to non-control respectively, i.e., feelings is arranged according to the threshold value of non-control at this time
Condition controls air compressor machine.I.e. if non-control is more than threshold value at this moment, carry out starting spare executing agency even
Be alarm operation, according to the actual situation depending on.
(2) threshold value is arranged to control data, pushes back gas tank pressure data according to the actual range of multiple non-control is counter
The numerical value (such mode needs to collect a large amount of available datas and realized) that should have, according to the gas tank number pressure being derived by
It is compared according to threshold value.
Realize the fault tolerant operation to whole automatic control system at this time, i.e., when gas tank pressure data and non-control it
Between there is exception, non-control can be used, system is controlled, rather than directly shut down.
Under normal conditions, there is above-mentioned condition, generally the device efficiency of air compressor machine reduces or health fails.Because
Under normal conditions, even if higher or lower situation integrally occur in data, non-control also can gentle pressure tank in data
Meet correlation rule between data, rather than the numerical value of some non-control and/or multiple non-control is not fallen within pair
The limit section of data should be controlled.
Specifically, in some cases it may which the quantity of non-control, such as percent are set with the mode of ratio
33 or more non-control does not fall within the limit section of corresponding control data, then it is assumed that gas tank pressure data is invalid；And another
It under outer some cases, can also be configured according to the quantity of specific non-control, such as 2 non-control are not fallen within pair
It should control in the limit section of the value of data, then it is assumed that control data invalid.In addition, in some non-control and gas tank pressure
When force data is strong incidence relation or the extremely important non-control, when the non-control does not fall within corresponding control data
Limit section, directly think that gas tank pressure data is invalid.Above-mentioned several situations need to be determined according to the actual situation.
It more preferably, in the present embodiment, further include to new collected process data in data correlation processing step S2
Judged:
It is taken when the numerical value of some key non-control and/or multiple non-control falls into gas tank pressure data correspondence
When the limit section of value, then it is assumed that meet related relevance rule between gas tank pressure data non-control associated with it,
Then judge that gas tank pressure data is effective, and the control foundation as corresponding air compressor air storage tank pressure；
Judgement simultaneously does not fall between the non-control gas tank pressure data associated with it in limit section and does not meet phase
Relevance rule is closed, and is further contemplated that the non-control is invalid data, is reported an error to non-control, and not as
The diagnosis basis of air compressor air storage tank pressure.
With it is being mentioned in above-mentioned data correlation processing step S2 on the contrary, the step for judge gas tank pressure data whether be
Normal data, specifically, if most of non-control or some crucial non-control fall into the gas tank pressure
The limit section of data, then it is assumed that gas tank pressure data is normal data.
At this point, corresponding to this kind of situation, it is preferable that in the present embodiment, for some non-control and/or multiple non-
The value of control data falls into the case where limit section of corresponding control data, judgement do not fall within the non-control in limit section with
Related relevance rule is not met between associated gas tank pressure data, and is further contemplated that the non-control is invalid number
According to, report an error to non-control and not as diagnosis air compressor air storage tank pressure control foundation.
And then judge to obtain that the element of the non-control or relevant device are abnormal, and take corresponding operating.I.e. at this time not
The non-control for falling into deviation profile region can be abnormal data under normal conditions, and artificial/machine is needed accordingly to be judged
Operation.
It is preferred that in the present embodiment, when some key non-control and/or multiple non-control
When numerical value falls into gas tank pressure data and corresponds to the limit section of value, and there is the numerical value of one and/or several non-control not
When falling into gas tank pressure data and corresponding to the limit section of value, diagnose its do not met between associated gas tank pressure data it is related
Relevance rule, and according to the situation that reports an error of non-control, shift to an earlier date according to gas tank pressure data and/or hysteresis manner is to sky
Press reservoir pressure carries out PREDICTIVE CONTROL.
Specifically, when limit section due to being in gas tank pressure data in most of non-control, non-control
Not as the control foundation of air compressor machine, but its non-control for going beyond the limit of process section can also illustrate that related content occurs
Problem (collection terminal itself goes wrong or data acquisition goes wrong), therefore the feelings that can be reported an error at this time according to non-control
Condition, in advance and/or lag is implemented to control air compressor air storage tank pressure.
At this point, realizing when non-control occurs abnormal and carrying out PREDICTIVE CONTROL according to gas tank pressure data.
In the present embodiment, air compressor air storage tank pressure is in certain gas tank pressure value, gas tank pressure rise/fall speed,
Air compressor machine throughput, compressor operation/dwell time, motor current and motor voltage actual value distinguish it is corresponding
Limit section is compared, if only air compressor machine throughput exceeds corresponding limit section, therefore by the air compressor machine of air compressor machine
Throughput reports an error.
Meanwhile by the way of PREDICTIVE CONTROL, exceed corresponding limit section or other situations in air compressor machine throughput,
According to the actual conditions of gas tank pressure, in advance/lag is carried out to air compressor machine and is controlled.
It wherein, can be to air compressor machine when threshold value of the gas tank pressure data beyond setting for above-mentioned any situation
Execute relevant operation.And for PREDICTIVE CONTROL, threshold value can be adjusted according to reporting an error for non-control, so that gas tank pressure
Force data is controlled before reaching the threshold value of script.
Wherein, PREDICTIVE CONTROL and faults-tolerant control are existing for the relationship of "and/or".
In addition, the realization based on above-mentioned any content, in the present embodiment, the limit section replace with positive and negative deviation
Range, wherein the acquisition modes of the positive and negative deviation range the following steps are included:
In air compressor machine actual motion, it is continual detect the air compressor machine include gas tank pressure data with and its be associated with
Non-control including data；
The average value relation curve of correspondence non-control of the gas tank pressure data in specified value is obtained, and establishes mark
Quasi normal distribution law curve；
