Description
Technical field
The present invention relates to electric energy meter technical field more particularly to a kind of phase identification sides of platform area based on Bezier algorithm
Method.
Background technique
There are two types of the prior art is general to the ammeter of the single-phase work in platform area and the phase information acquisition of acquisition equipment
Method:
One is phase-detection is carried out by way of power failure, that is, stops the electricity of a certain phase, which single-phase electricity then detected
Table stops working, then may determine that these single-phase electric meters are to be connected in this phase that the power supply failed, but use this side
Method will affect the life of normal day of resident first, and secondly each area requires artificial treatment, handles and its spends human and material resources,
If need to re-start update after number of users variation or user location variation again in most background partition.
There are also one is a kind of novel routing module is arranged in platform area, increase picking platform area on this routing module
Electric energy meter phase bit function, but this structure need concentrator, routing module and electric energy meter all to support just can be with, promote cost
It is higher, and this technical solution initiative, in routing producer, each producer's scheme is different, and electric energy meter and concentrator need to fit
Different schemes is made with routing module, will cause the waste of resource in this way.
Summary of the invention
The technical problems to be solved by the present invention are: a kind of platform area phase recognition methods based on Bezier algorithm are provided,
The separate of detection single-phase meter can be carried out using the voltage data that concentrator itself acquires in this way, facilitates detection phase letter
Breath, and cost is relatively low.
The technical scheme adopted by the invention is that: a kind of platform area phase recognition methods based on Bezier algorithm, it includes
Following steps:
S1, concentrator acquire the three-phase voltage value UA of summary table every the W time simultaneouslyX、UBX、UCXAnd each single-phase meter voltage

The voltage value of acquisition, UmXFor the voltage value of m-th of single-phase meter X time acquisition；
S2, after the operation Y time, n times data is acquired, the three-phase voltage value UA of summary table is obtained1、UB1、UC1, UA2、UB2、
UC2、、、、UAN、UBN、UCNAnd single-phase meter voltage data Um1、Um2、、、、UmN；
S3, calculate the summary table Y time in three-phase voltage average valueWith single-phase meter average voltage
Wherein,
S4, single-phase meter average voltage is calculatedWith the average value of summary table three-phase voltageDifference HAm,
HBm, HCm,
S5, single-phase meter is calculated separately to the standard deviation of A, B, C three-phase,
S6, to obtain the voltage that the single-phase meter is connect according to step S5 three obtained standard deviation separate；
S7, step S1-S6 is executed to each single-phase meter user, it is separate obtains the voltage that each single-phase meter is connect.
The step S6 is specifically referred to, and compares three standard deviations, select the smallest standard deviation it is corresponding it is separate be single
The connect voltage of phase table is separate.
If three obtained standard deviation is both greater than Z, there is mistake in judgement, and mistake is reported.
It also needs to be inserted into the step of verifying the voltage-phase that this is obtained between step S6 and step S7.
The step of verifying is to repeat step S1-S6 to this single-phase meter, then by obtained result and knot before
Fruit is compared.
The step of verifying is to repeat step S1-S6 twice to this single-phase meter, then will three obtained knot in total
Fruit is compared, and judges whether identical, and if they are the same, then the result judged is correct, if not identical, mistake occurs in judgement,
And mistake is reported.
The W is 15 minutes.
The Y is 1 day.
Using above method compared with prior art, the invention has the following advantages that obtaining A, B, C three-phase by algorithm
Then standard deviation can be obtained according to this standard deviation between the voltage fluctuation curve between single-phase electric energy meter and three phases
Whether similar, i.e., standard deviation is smaller, i.e., closer to 0, similarity is higher, on the contrary then similarity is lower, with the electricity of some phase
It presses the curve of cyclical fluctuations similar, then may determine that this single-phase electric energy meter is exactly to be connected in this phase, do not need the behaviour that has a power failure in this way
Make, and do not need that additional routing module is arranged, so that phase-detection is more convenient, and testing cost is lower, detection
Accuracy rate is higher.
Detailed description of the invention
Fig. 1 is the curve graph that single-phase meter and A, B, C three-phase are formed in specific implementation.
Specific embodiment
The present invention is described further below in conjunction with attached drawing and specific embodiment, but the present invention be not limited only to it is following
Specific embodiment.
A kind of platform area phase recognition methods based on Bezier algorithm, it the following steps are included:
S1, concentrator acquire the three-phase voltage value UA of summary table every the W time simultaneouslyX、UBX、UCXAnd each single-phase meter voltage
Data UmX, wherein UAXFor the voltage value of A phase X time acquisition, UBXFor the voltage value of B phase X time acquisition, UCXFor C phase X time
The voltage value of acquisition, UmXFor the voltage value of m-th of single-phase meter X time acquisition；W is set as detecting for 15 minutes in this specific embodiment
Once,
S2, after the operation Y time, n times data is acquired, the three-phase voltage value UA of summary table is obtained1、UB1、UC1, UA2、UB2、
UC2、、、、UAN、UBN、UCNAnd single-phase meter voltage data Um1、Um2、、、、UmN；It is 1 day that Y is arranged in this specific embodiment,
Acquire 96 data within i.e. this specific embodiment one day, as shown in following table one:
Table one
S3, calculate the summary table Y time in three-phase voltage average valueWith single-phase meter average voltage
Wherein,
It is available
S4, single-phase meter average voltage is calculatedWith the average value of summary table three-phase voltageDifference HAm,
