It is said that in general, electric equipment 10 is during performing control flow, it can be along with control flow with electric signal
Carry out and produce, in the different operating stage, the version that specifically fluctuates, therefore arithmetic and control unit 104 can be by comparison electric signal
The sample characteristics of eigenvalue cluster and the control flow prestored, the control flow currently carried out with identification electric equipment 10.?
In one embodiment, the corresponding sample characteristics respectively of each control flow in control flow group, arithmetic and control unit 104 can be by comparison
With the sample characteristics corresponding to the eigenvalue cluster of electric signal and the plurality of control flow, with select in control flow group have with
With the control flow of the most like sample characteristics of the eigenvalue cluster of electric signal as the current control flow of electric equipment 10.
Described control flow group such as include electric equipment 10 may perform control flow.With electric equipment 10 it is
As a example by coffee machine, if coffee machine provides " Mocha coffee ", " latte ", " caffe american ", " Cappuccino " four kinds to brew choosing
, then operation recognition system 100 brews, for these four kinds, control flow A, B, C, D that option is corresponding by prestoring.In an embodiment
In, the information of control flow group is such as embedded in operation recognition system 100 the storage media being available for arithmetic and control unit 100 access
(such as memorizer, consulting table (look-uptable, LUT) etc.).
Each control flow A, B, C, D include one or more operational phases of correspondence respectively.It is coffee at electric equipment 10
In the example of machine, these one or more operational phases such as include boiler heating period, electromagnetic valve switch stage, coffee extracted rank
Section and grinding stage at least one.For different control flow A, B, C, D, the execution sequence of each operational phase, execution item
Mesh, execution time, element control parameters (such as extracting pressure, boiler temperature, discharge etc.) all may be different, therefore electric equipment 10
Presented when performing this multiple control flow A, B, C, D also can be different with the waveform change of electric signal.Utilize this characteristic,
Definable goes out each control flow A, B, C, D and is distinguished the use electric signal fluctuation characteristic model of correspondence, and these multiple electric signals fluctuate
Feature model can be described by the sample characteristics (such as the characteristic point set of corresponding specific waveforms change) preset.Work as operation control
The portion being similar to a certain control flow (such as control flow A) with the eigenvalue cluster of electric signal of electric equipment 10 judged by device 104
Divide or whole sample characteristics, and be different from the sample characteristics corresponding to other control flows (such as control flow B, C, D), computing control
Device 104 processed is control flow A by picking out the current control flow that electric equipment 10 currently carries out, and is the most brewing and is rubbing
Card coffee.
In step 206, arithmetic and control unit 104 judgement electric signal is corresponding to the fluctuation characteristic and first of the first operational phase
Whether the deviation of operating parameter is in a tolerance.The most then terminate flow process.If it is not, then enter step 208.
First operational phase can be any operation stage in current control flow.First operating parameter can be any
It is associated with the operating parameter of the first operational phase.For example, the first operating parameter can be the default behaviour of the first operational phase
Make time, preset voltage value, pre-set current value or predetermined power factor value.If select with in current control flow to time requirement
Most stringent of one or more operational phase is as the first operational phase, it is preferred that optional presetting with the first operational phase
Operating time is as the first operating parameter.As a example by coffee machine, coffee machine is when infusing coffee, and the length of coffee extracted time is past
Toward having dominated the mouthfeel of coffee, therefore, the optional coffee extracted stage as the first operational phase, and with the coffee extracted stage
The predetermined registration operation time is as the first operating parameter standard the most abnormal as passing judgment on electric equipment 10.Such as, arithmetic and control unit
104 is the control that correspondence brews Mocha coffee going out the current control flow of electric equipment 10 based on the electricity consumption signal recognition recorded
After flow process A, will further determine this with the change of waveform that in electric signal correspondence control flow A, the coffee extracted stage is presented
Whether interval length meets default coffee extracted phases-time requirement, such as, maintain the S second.If arithmetic and control unit 104 detects
Though have the waveform variation characteristic in the coffee extracted stage of corresponding control flow A with electric signal, but this section of waveform change generation
Deviation between the predetermined registration operation time in time interval and coffee extracted stage exceeds a tolerance, then judge electric equipment 10
For exception, and enter step 208.
In step 208, when with electric signal corresponding to the fluctuation characteristic of the first operational phase and the deviation of the first operating parameter
Beyond tolerance, arithmetic and control unit 104 will trigger an alarm events.Alarm events can be any with sound, light, wired,
Wireless mode output is to reach the event of alarming effect, and such as flashing light, startup buzzer, output wire/wireless alerting are to outward
Portion's monitoring management apparatus etc..As a example by alarm events is for sending wireless warning signal, arithmetic and control unit 104 will control signal receiving/transmission
Device 106 transmits alerting to remote side administration platform 16.Respond the alerting from operation recognition system 100, remote side administration
Platform 16 can perform remote side administration and such as update the anomalous identification value of electric equipment 10, newly-increased anomalous identification logic, automatic informing
The operations such as maintainer, renewal maintenance record form, to notify that the running of related personnel or monitoring device electric equipment 10 occurs
Abnormal, and update relevant monitor data.
Fig. 3 illustrates another example flow chart of the operation recognition methods for electric equipment 10.Main difference with Fig. 2 embodiment
Not being, be "Yes" when the judged result of step 206 in the present embodiment, flow process will enter step 302, arithmetic and control unit 104 meeting
Determine whether this use electric signal fluctuation characteristic corresponding to the first operational phase and the one second operation ginseng of the first operational phase
Whether the deviation of number is in another tolerance.If judged result is "No", then entering step 208, arithmetic and control unit 104 will touch
Send out alarm events.
Second operating parameter can be any be associated with for the first operational phase but the operation different with the first operating parameter ginseng
Number.For example, the second operating parameter can be the predetermined registration operation time of the first operational phase, preset voltage value, predetermined current
Value or predetermined power factor value, but there is different electric parameter types from the first operating parameter.Such as, when the first operating parameter
Being the predetermined registration operation time of the first operational phase, the second operating parameter is then the preset voltage value of the first operational phase, presets electricity
Flow valuve or predetermined power factor value at least one of which.
In one embodiment, arithmetic and control unit 104 can judge following condition (1), (2), (3) at least one in step 302,
And when discovery condition is unsatisfactory for trigger alarm events:
Condition (1) is electric in tolerance with the difference of the preset voltage value of corresponding first operational phase with the magnitude of voltage of electric signal
In the range of pressure；Condition (2) is to tolerate with the difference of the pre-set current value of corresponding first operational phase with the current value of electric signal
In current range；Condition (3) is the predetermined power factor value with the power factor value of electric signal with corresponding first operational phase
Difference is in the range of tolerance power factor.
For example, if include current signal and the power factor signal measuring self-powered input 12 with electric signal,
When arithmetic and control unit 104 was judged with electric signal corresponding to wave time feature and first operational phase of the first operational phase
The deviation of predetermined registration operation time, in a tolerance, will further determine with electric signal at the electricity corresponding to the first operational phase
Flow valuve feature and the power factor value tag pre-set current value compared to the first operational phase and the deviation of predetermined power factor value
In the range of whether respectively falling in tolerance current range and tolerance power factor.
In one embodiment, arithmetic and control unit 104 also can determine whether other behaviour using electric signal corresponding to current control flow
Whether the wave character making the stage meets the condition of certain operational parameters.For example, electrical equipment is identified when arithmetic and control unit 104
Equipment 10 is carrying out the coffee extracted stage of control flow A, and its wave character is compared to first behaviour in coffee extracted stage
The deviation making parameter falls in a tolerance, and now arithmetic and control unit 104 will further determine with electric signal corresponding to control
In flow process A, whether the wave character of other operational phases (such as the boiler heating period) meets this behaviour corresponding to other operational phases
Make the condition of parameter, and when judged result is "No", trigger alarm events.
By the way, can determine whether that electric equipment 10 inner member, whether according to standard/preset state running, enters
And guarantee the quality of electric equipment 10 output.
Fig. 4 illustrates the example oscillogram using electric signal that electric equipment 10 performs to be presented during a current control flow.?
In this example, electric equipment 10 is a coffee machine, includes the power measuring the energization input 12 from electric equipment 10 with electric signal
Factor signal and current signal, represent with curve 402 and 404 respectively.It will be appreciated that the waveform change shown in Fig. 4 is only
In order to help to understand the present invention, and it is not used to limit the present invention.
First at period T0, coffee machine is in holding state, and now the value of power factor signal 402 maintains an initial value
(about 0.8), and current signal 404 maintains low current value (less than 1 ampere).
Then at period T1, the value of power factor signal 402 initial value when standby is promoted to maximum and (approximates
1), current signal 404 is then maintained at low current value.This represents that the single phase ac motor in coffee machine operates to carry out
Grind.Therefore, when power factor signal 402 and current signal 404 present the waveform change of so period T1, represent coffee machine and work as
Before grinding stage of being in control flow.
At period T2, the value of power factor signal 402 is down to intermediate value (about 0.5), and current signal 404 is then pulled up to
High current value (about 14～16 amperes).This represents that coffee machine is made the ratio of virtual work and improved, and is just passing to big electric current inside device and enter
Row heating.Therefore, when power factor signal 402 and current signal 404 present so period T2 waveform change, represent coffee machine and work as
Before boiler heating period of being in control flow.And period T12 and period T23, represent the most respectively opens solenoid valve and
Close the stage of electromagnetic valve.
At period T3, power factor signal 402 presents waveform change during similar period T1, this table with current signal 404
Show that coffee machine enters the grinding stage in control flow once again.
At period T4, power factor signal 402 presents waveform change during similar period T2, this table with current signal 404
Show that coffee machine enters the boiler heating period in control flow once again.And the transition period T34 between period T3 and T4, and the phase
Between transition period T45 between T4 and T5, represent opens solenoid valve the most respectively and close the stage of electromagnetic valve.
At period T5, waveform when power factor signal 402 presents similar period T0 with current signal 404 changes, therefore,
Represent coffee machine and return to holding state once again.
Research finds, in most application, the power factor signal waveform change of electric equipment 10 can be the most anti-
Reflect electric equipment 10 in the operation of different phase.Therefore, in one embodiment, power factor signal can be based purely on to identify electricity
The operational configurations of device equipment 10 (that is, for operate discriminatory analysis only include with electric signal measure the power supply from electric equipment 10
The power factor signal of input 12).In another embodiment, can be further combined with the current signal of electric equipment 10, voltage news
Number and/or other electric parameter identify the operational configurations of electric equipment 10, with the accuracy of lifting operation identification.Such as Fig. 4 institute
Showing, arithmetic and control unit 104 is that the feature of power factor signal and the current signal consumed based on electric equipment 10 identifies electricity
Device equipment 10 is presently in the operational phase.
In sum, the operation recognition methods of electric equipment proposed by the invention and apply its operation recognition system,
Based on electric equipment can use electric signal, the current control flow performed by identification electric equipment and operational phase, and judge
Whether electric equipment performs one or more operational phases of this flow process based on parameter preset.Therefore, even if electrical equipment the most in appearance
Equipment is in the state that can operate, and still can send warning when the operation of electric equipment deviates standard setting, thereby ensuring that electrical equipment
Equipment performs the output quality of automatic flow.
The present invention is been described by by above-mentioned related embodiment, but above-described embodiment is only the example implementing the present invention.
It must be noted that, the embodiment disclosed is not limiting as the scope of the present invention.On the contrary, without departing from the present invention spirit and
