Below will explain content of the present invention by embodiment.The palpus expositor, embodiments of the invention are not to limit the present invention must can implement as following examples and graphic described any specific environment, application or particular form.Therefore, relevant following examples and graphic explanation only are explaination purpose of the present invention, but not in order to limiting the present invention, and this case scope of asking, and are as the criterion with claims.In addition, in following examples and graphic in, omit and do not illustrate with the non-directly related assembly of the present invention, and in graphic the size relationship of each inter-module only for asking easy understanding, but not in order to limit actual ratio.
The first embodiment of the present invention is an electricity exception arrangement for detecting 1.Fig. 1 is an assembly schematic diagram of electricity exception arrangement for detecting 1.As shown in Figure 1, electricity exception arrangement for detecting 1 comprises a reservoir 11, a power information acquisition device 13 and an electrically connect at least to the processor 15 of reservoir 11 and power information acquisition device 13.Must the expositor, except said modules, electricity exception arrangement for detecting 1 of the present invention can comprise other assembly, so considers the principle that explanation is simplified, and is omitted in this embodiment without directly related assembly with the present invention.
On the other hand, power information acquisition device 13 treats wherein that in order to capture a power information 22 to be measured for the treatment of electricity measurer 3 electricity measurer 3 and these belong to same type with reference to electrical equipment 5.For example, treat that electricity measurer 3 and these can be any electronic installations that TV, refrigerator, desk lamp, micro-wave oven, baking box, washing machine, air conditioner etc. need power supply with reference to electrical equipment 5.
How relevant electricity exception arrangement for detecting of the present invention 1 treats that with reference to power information 20 judgements electricity measurer 3 abnormals will be further described below according to these in reservoir 11.At first, the processor 15 of electricity exception arrangement for detecting 1 can be in response to the type for the treatment of electricity measurer 3 or according to user's definition, define several different parameters of electric power types, wherein these parameters of electric power types are limited but can comprise that electric switch number of times in power consumption, electrical equipment opening time, electrical equipment shut-in time, electricity consumption duration, a hour, electrical equipment are opened the number of times that surpasses one minute, in the week, electrical equipment uses T.T. etc. type.Must the expositor, this area tool usually know the knowledgeable should according to the above-mentioned type think easily and how different parameters of electric power type to agree with the dissimilar or user's who treats electricity measurer 3 different definition.
Further, suppose that these parameters of electric power types comprise power consumption and electrical equipment opening time, and processor 15 defines respectively power consumption and electrical equipment open-interval parameters of electric power mobility scale is 50 watts and 20 minutes, and these power consumption differences each other with reference to electric power event 20a will be classified as one group in 50 watts; And these electrical equipment opening time differences each other with reference to electric power event 20a will be classified as one group in 20 minutes.Appoint in the grouping of above-mentioned power consumption and the grouping of electrical equipment opening time and get one group and can set up an electric power sample 20b.More detailed description can be consulted exemplary illustrating described later.
In the present embodiment, side-play amount 44 judgements between the Second principal component, direction 42 that processor 15 distributes according to the first principal component direction 40 of each the first parameters of electric power distribution 20c and this second parameters of electric power treat that whether abnormal occurs electricity measurer 3.In addition, processor 15 more defines a divergence threshold value, and when this difference surpassed this divergence threshold value, electricity measurer 3 abnormals were treated in judgement.Must the expositor, in other embodiment, processor 15 also can be treated whether abnormal of electricity measurer 3 according to the alternate manner judgement, is not limited to the described judgment mode of the present embodiment.For example, processor 15 can be set up a parameters of electric power covering scope according to each the first parameters of electric power distribution 20c, and whether is positioned at this parameters of electric power covering scope according to electric power event 22a to be measured, and whether abnormal of electricity measurer 3 is treated in judgement.
Based on the ins and outs of part electrical equipment or user's peculiar electricity consumption behavior, each may belong to normally with reference to the first parameters of electric power distribution 20c of electric power sample 20b and the difference between the second parameters of electric power distribution 20d, and then causes processor 15 erroneous judgements to treat electricity measurer 3 abnormals.For example, suppose that several treat that with reference to electrical equipment 5 and one electricity measurer 3 is all the electric fan that can set high wind, apoplexy and weak three kinds of patterns of wind, wherein the power consumption of high wind, apoplexy and weak wind is respectively 100 watts, 50 watts and 25 watts.Under this hypothesis, when these several with reference to several information that capture under weak wind pattern with reference to power information 20 of electrical equipment 5, and during the information that captures under the high wind pattern until the power information to be measured 22 of electricity measurer 3, the power consumption difference that processor 15 will cause because of weak wind pattern and high wind pattern, electricity measurer 3 abnormals are treated in erroneous judgement.
In order to reduce the probability of processor 15 erroneous judgements, it is an interval type parameters of electric power type that the processor 15 of the present embodiment more defines at least one of these parameters of electric power types.Particularly, processor 15 is when defining these parameters of electric power types, and defining simultaneously these parameters of electric power classification of type is interval type parameters of electric power type or non-interval type parameters of electric power type.Because having one, interval type parameters of electric power type tolerates the interval, so that can reduce the difference between respectively this first parameters of electric power distribution and the distribution of this second parameters of electric power.
Be example for above-mentioned example again, suppose that several treat that with reference to electrical equipment 5 and one electricity measurer 3 is all the electric fan that can set high wind, apoplexy and weak three kinds of patterns of wind, wherein the power consumption of high wind, apoplexy and weak wind is respectively 100 watts, 50 watts and 25 watts.Processor 15 is as long as setting the tolerance interval of power consumption is 25 watts to 100 watts, treat electricity measurer 3 will be not can be because of the difference of the pattern of use, and be mistaken for abnormal by processor 15.
Needing the expositor, is not that all parameters of electric power types all can be set as interval type parameters of electric power type.Parameters of electric power types such as electrical equipment opening time or electrical equipment shut-in time, because itself not having the above-mentioned ins and outs as power consumption or electricity consumption duration, if be the interval type parameters of electric power therefore be set, can because of too loose criterion, cause processor 15 judgements to treat that the accuracy rate of electricity measurer 3 abnormals reduces on the contrary.
How to judge and treat electricity measurer 3 abnormals in order more to offer some clarification on electricity exception arrangement for detecting 1 of the present invention, will via one exemplary illustrate as follows.Must the expositor, what this was exemplary is not to limit the present invention only mode as described to operate for example, and limits only unrestricted the present invention in order to explanation in exemplary all that suppose in for example.
In this example, suppose to have four with reference to electrical equipment, be respectively with reference to electrical equipment 51, with reference to electrical equipment 52, with reference to electrical equipment 53 and with reference to electrical equipment 54 (following general designation is with reference to electrical equipment 51-54), and one is treated electricity measurer 3.Processor 15 has defined four parameters of electric power types, be respectively power consumption (wattage), electrical equipment opening time, electrical equipment shut-in time and electricity consumption duration (minute).Processor is according to these four parameters of electric power types, set up four with reference to electric power event 20a from described four with reference to electrical equipment 51-54 four with reference to power information 20 respectively, namely set up with reference to electric power event 20a-1, with reference to electric power event 20a-2, with reference to electric power event 20a-3 and with reference to electric power event 20a-4, and be expressed as follows with the form of { power consumption, electrical equipment opening time, electrical equipment shut-in time, electricity consumption duration }:
With reference to electric power event 20a-1:{550,07:05,07:30,25}
With reference to electric power event 20a-2:{600,07:15,07:45,30}
With reference to electric power event 20a-3:{650,07:20,07:35,15}
With reference to electric power event 20a-4:{625,08:00,09:00,60}
Based on above-mentioned hypothesis, the parameters of electric power mobility scale that processor 15 more defines power consumption, electrical equipment opening time, electrical equipment shut-in time, electricity consumption duration is 25 watts, 15 minutes, 5 minutes and 15 minutes.Then, processor 15 is classified with reference to electric power event 20a to above-mentioned four according to above-mentioned four electronic scopes of parameters of electric power.
Particularly, due to reference electric power event 20a-2 and with reference to the power consumption difference of electric power event 20a-4 in 25 watts, therefore the power consumption grouping classifies as same group with reference electrical equipment 52 and with reference to electrical equipment 54, and respectively do for oneself one group with reference to electrical equipment 51 and with reference to electrical equipment 53.Due to the electrical equipment of reference electric power event 20a-1, with reference to electric power event 20a-2 and with reference to the electrical equipment opening time difference of electric power event 20a-3 in 15 minutes, therefore electrical equipment opening time grouping is with reference electrical equipment 51, classify as same group with reference to electrical equipment 52 and with reference to electrical equipment 53, and do for oneself one group with reference to electrical equipment 54.
Due to reference electric power event 20a-1 and with reference to the electrical equipment shut-in time difference of electric power event 20a-3 in 20 minutes, therefore the grouping of electrical equipment shut-in time classifies as same group with reference electrical equipment 51 and with reference to electrical equipment 53, and respectively does for oneself one group with reference to electrical equipment 52 and with reference to electrical equipment 54.Due to reference electric power event 20a-1, with reference to electric power event 20a-2 and with reference to the electricity consumption duration difference of electric power event 20a-3 in 10 minutes, therefore electricity consumption duration grouping is with reference electrical equipment 51, classify as same group with reference to electrical equipment 52 and with reference to electrical equipment 53, and do for oneself one group with reference to electrical equipment 54.
In then own demand grouping of processor 15, the grouping of electrical equipment opening time, the grouping of electrical equipment shut-in time and the grouping of electricity consumption duration, find out all permutation and combination, to set up several with reference to electric power sample 20b.Based on the explanation simplification principle, below will be with going on to say with reference to electric power sample 20b:{600～625,07:05～07:20,07:30～07:35,15～30} wherein, and this area tool knows that usually the knowledgeable can think with reference to electric power sample 20b according to this and unaccounted other enforcement aspect with reference to electric power sample 20b easily.
Below explanation sees also Fig. 2 A and Fig. 2 B, and wherein Fig. 2 A and Fig. 2 B are the schematic diagram with reference to the one first parameters of electric power distribution 20c of electric power sample 20b of the first embodiment.Particularly, Fig. 2 A describes above-mentioned power consumption with reference to electric power sample 20b and electrical equipment open-interval one two-dimensional space parameters of electric power distribution plan, and Fig. 2 A describes the two-dimensional space parameters of electric power distribution plan of above-mentioned electrical equipment shut-in time with reference to electric power sample 20b and electricity consumption duration, therefore be above-mentioned the first parameters of electric power distribution 20c with reference to electric power sample 20b in conjunction with Fig. 2 A and Fig. 2 B.
As shown in Fig. 2 A, above-mentioned power consumption and the electrical equipment opening time with reference to electric power sample 20b has a first principal component direction 40a, and wherein first principal component direction 40a is in order to represent the main variation direction of above-mentioned power consumption with reference to electric power sample 20b and electrical equipment open-interval one.In addition, as shown in Fig. 2 B, above-mentioned electrical equipment shut-in time and the electricity consumption duration with reference to electric power sample 20b has a first principal component direction 40a, and first principal component direction 40b is in order to represent the main variation direction of above-mentioned electrical equipment shut-in time with reference to electric power sample 20b and electricity consumption duration.In four-dimentional space, can learn the first principal component direction 40 of above-mentioned the first parameters of electric power distribution 20c with reference to electric power sample 20b in conjunction with first principal component direction 40a and first principal component direction 40b.
Due to the above-mentioned distribution that belongs to a four-dimentional space parameters of electric power with reference to the first parameters of electric power distribution 20c of electric power sample 20b, and because four-dimentional space is difficult to use diagrammatic representation, thus following will be only with power consumption and electrical equipment open-interval one two-dimensional space parameters of electric power distribution plan as follow-up explanation.Yet this area tool is known the knowledgeable usually, should be easily via the explanation of two-dimensional space parameters of electric power distribution plan, think easily and the distribution of the four-dimentional space parameters of electric power of above-mentioned the first parameters of electric power distribution 20c with reference to electric power sample 20b.
Below will how to calculate difference between the first parameters of electric power distribution 20c and the second parameters of electric power distribution 20d via Fig. 3 A explanation processor 15, wherein Fig. 3 A is the two-dimensional space schematic diagram with reference to the one second parameters of electric power distribution 20d of electric power sample 20b of the first embodiment.As shown in Figure 3A, when in conjunction with power consumption be 650 watts and electrical equipment opening time be 07:05 electric power event 22a to be measured to above-mentioned with reference to electric power sample 20b after, original above-mentioned power consumption and electrical equipment open-interval one first principal component direction 40a with reference to electric power sample 20b will produce because of adding of electric power event 22a to be measured a skew 44a.At this moment, above-mentioned power consumption and electrical equipment open-interval one first principal component direction 40a with reference to electric power sample 20b will be offset to Second principal component, direction 42a.
Similar in appearance to the explanation of above-mentioned Fig. 3 A, for electrical equipment shut-in time and electricity consumption duration, can calculate equally whether produce a skew 44b between first principal component direction 40b and Second principal component, direction 42b.In four-dimentional space, can obtain skew between first principal component direction 40 and Second principal component, direction 42 in conjunction with skew 44a and skew 44b, namely obtain the difference between first principal component direction 40 and Second principal component, direction 42.
Via above-mentioned explanation, clearly demonstrated processor 15 and how to have calculated difference between first principal component direction 40 and Second principal component, direction 42.By that analogy, processor 15 can calculate the difference between above-mentioned all first parameters of electric power with reference to electric power sample 20b distribute and this second parameters of electric power distributes.In the present embodiment, processor 15 more defines a divergence threshold value, and the difference between first principal component direction 40 and Second principal component, direction 42 is when surpassing this divergence threshold value, and electricity measurer 3 abnormals are treated in judgement.
Particularly, if the difference that the first parameters of electric power distributes and this second parameters of electric power distributes with reference to electric power sample 20b does not surpass this divergence threshold value, processor 15 will calculate the next difference that the first parameters of electric power distributes and this second parameters of electric power distributes with reference to electric power sample 20b, and judge whether this difference surpasses this divergence threshold value, until all have been calculated with reference to the difference that the first parameters of electric power distributes and this second parameters of electric power distributes of electric power sample 20b.If all differences that the first parameters of electric power distributes and this second parameters of electric power distributes with reference to electric power sample 20b all surpass this divergence threshold value, expression treats that the electricity consumption behavior of electricity measurer 3 is neither identical with several electricity consumption behaviors with reference to electrical equipment.In other words, this moment, processor 15 was treated electricity measurer 3 abnormals with judgement.
The processor 15 of the present embodiment is via the inner product value that calculates between first principal component direction 40 and Second principal component, direction 42, as the difference between first principal component direction 40 and Second principal component, direction 42, wherein this difference of the larger expression of inner product value is less, represents that this difference is larger otherwise inner product value is less.Yet in other embodiment, processor 15 also can calculate difference between first principal component direction 40 and Second principal component, direction 42 via alternate manner, but not is subject to the form of the described inner product of the present embodiment.
Below will be via Fig. 3 B, further illustrate interval type parameters of electric power type for the impact of the difference between the first parameters of electric power distribution 20c and the second parameters of electric power distribution 20d, wherein Fig. 3 B is the two-dimensional space schematic diagram with reference to another the second parameters of electric power distribution 20d of electric power sample 20b of the first embodiment.
Power consumption shown in Fig. 3 B is defined as an interval type parameters of electric power type by processor 15, and the tolerance interval of power consumption is defined as 550 watts to 650 watts.So, when in conjunction with power consumption being 550 watts to 650 watts and electrical equipment opening time is that the electric power event 22a to be measured of 07:05 is to above-mentioned during with reference to electric power sample 20b, original above-mentioned power consumption and electrical equipment open-interval one first principal component direction 40a with reference to electric power sample 20b will can not produce because of adding of electric power event 22a to be measured skew.At this moment, above-mentioned power consumption and electrical equipment open-interval one first principal component direction 40a with reference to electric power sample 20b is identical with Second principal component, direction 42a, and namely first principal component direction 40a can't change because of adding of electric power event 22a to be measured.
Similarly, based on the explanation of above-mentioned Fig. 3 B, this area tool knows that usually the knowledgeable should think easily and how interval type parameters of electric power type impacts for the first principal component direction 40b of electrical equipment shut-in time and electricity consumption duration and the skew 44b between Second principal component, direction 42b.
Via above-mentioned exemplary illustrating, this area tool knows that usually the knowledgeable should understand technical characterictic of the present invention fully, simultaneously can be according to above-mentioned exemplary illustrating, think easily and relevant to the technology of the present invention but undeclared in upper other enforcement aspect.
