The sample characteristics corresponding to the eigenvalue cluster of electric signal and multiple control flow, with selected from control flow group have with
Current control flow of the control flow for the sample characteristics for using the eigenvalue cluster of electric signal most like as electrical equipment 10.
The control flow that the control flow group may be executed for example including electrical equipment 10.It is with electrical equipment 10
For coffee machine, if coffee machine provides " Mocha coffee ", " latte ", " caffe american ", four kinds of " Cappuccino " brew choosing
, then operation recognition system 100, which will be prestored, brews option corresponding control flow A, B, C, D for this four kinds.In an embodiment
In, the information of control flow group is for example embedded in the storage media accessed in operation recognition system 100 for arithmetic and control unit 100

In step 206,104 judgement of arithmetic and control unit corresponds to the fluctuation characteristic and first of the first operational phase with electric signal
Whether the deviation of operating parameter is in a tolerance.If so, terminating process.If it is not, then entering 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 selection in current control flow to time requirement
The most stringent of one or more operational phase is as the first operational phase, preferably, presetting with the first operational phase may be selected
Operating time is as the first operating parameter.By taking coffee machine as an example, for coffee machine when infusing coffee, the length of coffee extracted time is past
Toward the mouthfeel for having dominated coffee, therefore, the coffee extracted stage may be selected as the first operational phase, and with the coffee extracted stage
The predetermined registration operation time as the first operating parameter as judge electrical equipment 10 whether Yi Chang standard.For example, arithmetic and control unit
104 in the control that the current control flow for going out electrical equipment 10 based on the electricity consumption signal recognition measured is that correspondence brews Mocha coffee
After process A, it will further determine this with electric signal and correspond to what the waveform that the coffee extracted stage is presented in control flow A changed
Whether section length meets preset coffee extracted phases-time requirement, such as maintains S seconds.If arithmetic and control unit 104 detects
Though there is the waveform variation characteristic in the coffee extracted stage of corresponding control flow A with electric signal, what this section of waveform variation occurred
Deviation between time interval and the predetermined registration operation time in coffee extracted stage exceeds a tolerance, then judges electrical equipment 10
For exception, and enter step 208.
In step 208, when the deviation for the fluctuation characteristic and the first operating parameter for corresponding to for the first operational phase with electric signal
Beyond tolerance, arithmetic and control unit 104 will trigger an alarm events.Alarm events can be it is any with sound, light, it is wired,
Wireless mode output is to reach the event of warning effect, such as flashing light, starting buzzer, output wire/wireless alerting are to outer
Portion's monitoring management apparatus etc..By taking alarm events are to send wireless warning signal as an example, 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

It is abnormal, and update relevant monitor data.
Fig. 3 is painted another flow chart of the operation recognition methods for electrical equipment 10.With the main difference of Fig. 2 embodiment
It is not, when the judging result of step 206 is "Yes" in the present embodiment, process will enter step 302,104 meeting of arithmetic and control unit
Further judge that this is joined with electric signal corresponding to the fluctuation characteristic of the first operational phase and one second operation of the first operational phase
Whether several deviations is in another tolerance.If judging result is "No", 208 are entered step, arithmetic and control unit 104 will touch
Send out alarm events.
Second operating parameter, which can be, any is associated with the first operational phase but different with the first operating parameter operation 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.For example, when the first operating parameter
For 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, default electricity
Flow valuve or predetermined power factor value at least one of them.
In one embodiment, arithmetic and control unit 104 can step 302 judge following condition (1), (2), (3) at least first,
And alarm events are triggered when discovery condition is unsatisfactory for:
Condition (1) is with the difference of the preset voltage value of corresponding first operational phase with the voltage value of electric signal in tolerance electricity
It presses in range；Condition (2) is to be tolerated with the current value of electric signal with the difference of the pre-set current value of corresponding first operational phase
In current range；Condition (3) is to use the power factor value of electric signal and the predetermined power factor value of corresponding first operational phase
Difference is within the scope of tolerance power factor.
For example, if including the current signal and power factor signal for measuring confession electrical input 12 with electric signal,
When arithmetic and control unit 104 judges wave time feature and the first operational phase with electric signal corresponding to the first operational phase
The deviation of predetermined registration operation time will further determine with electric signal in a tolerance in the electricity for corresponding to for the first operational phase
Flow valuve feature and power factor value tag are compared to the pre-set current value of the first operational phase and the deviation of predetermined power factor value
Whether respectively fall within the scope of tolerance current range and tolerance power factor.
In one embodiment, arithmetic and control unit 104 also can determine whether other behaviour with electric signal corresponding to current control flow
Whether the wave character for making the stage meets the condition of certain operational parameters.For example, when arithmetic and control unit 104 identifies electric appliance
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 for making parameter is fallen in a tolerance, and arithmetic and control unit 104 will further determine with electric signal corresponding to control at this time
Whether the wave character of other operational phases (such as the boiler heating period) meets behaviour corresponding to other operational phases in process A
Make the condition of parameter, and when judging result is "No", triggers alarm events.
By the above-mentioned means, can further judge whether 10 internal element of electrical equipment operates according to standard/preset state, into
And ensure the quality of 10 output of electrical equipment.

First in period T0, coffee machine is in standby, and the value of power factor signal 402 maintains an initial value at this time
(about 0.8), and current signal 404 maintains low current value (less than 1 ampere).
Then in period T1, the value of power factor signal 402 from it is standby when initial value be promoted to maximum value and (be approximately equal to
1), and current signal 404 is then maintained at low current value.This indicates that the single phase ac motor in coffee machine is being operated to carry out
Grinding.Therefore, the waveform variation that such period T1 is presented with current signal 404 when power factor signal 402, represents coffee machine and works as
Before be in grinding stage in control flow.
In period T2, the value of power factor signal 402 is down to median (about 0.5), and current signal 404 is then pulled up to
High current value (about 14~16 amperes).This indicate coffee machine make virtual work ratio improve, and just passed to inside device high current into
Row heating.Therefore, change when such period T2 waveform is presented in power factor signal 402 and current signal 404, represent coffee machine and work as
Before be in boiler heating period in control flow.And period T12 and period T23, then respectively indicate opens solenoid valve and
Close the stage of solenoid valve.

Show the grinding stage that coffee machine enters once again in control flow.
In period T4, waveform variation when similar period T2, this table are presented with current signal 404 for power factor signal 402
Show the boiler heating period that coffee machine enters once again in control flow.And transition period T34 and phase between period T3 and T4
Between transition period T45 between T4 and T5, then respectively indicate opens solenoid valve and close the stage of solenoid valve.
In period T5, waveform variation when similar period T0 is presented with current signal 404 for power factor signal 402, therefore,
It represents coffee machine and returns to standby mode once again.
The study found that the power factor signal waveform variation of electrical equipment 10 can be substantially anti-in most of application
Electrical equipment 10 is reflected 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 are (that is, only include the power supply measured from electrical equipment 10 with electric signal for operate discriminance analysis
The power factor signal of input terminal 12).In another embodiment, it can be interrogated further combined with current signal, the voltage of electrical equipment 10
Number and/or other electric parameters identify the operational configurations of electrical equipment 10, to promote the accuracy of operation identification.Such as Fig. 4 institute
Show, arithmetic and control unit 104 is to identify electricity based on the feature of power factor signal and current signal consumed by electrical equipment 10
Device equipment 10 is presently in the operational phase.
