The core concept of technical solution provided by the present invention is described below:
Fig. 2 is referred to, low-voltage power distribution station area is divided into four grades on the topology:
The first order-low-tension transformer can be equipped with intelligent distribution transformer terminals beside low-tension transformer to monitor low-tension transformer
Data (voltage, electric current etc.)；
The second level-feeder pillar, above-mentioned low-tension transformer are connected with several feeder pillars, are coordination between each feeder pillar；
The third level-intelligent electric meter box unit, each feeder pillar can go out ABC three-phase, several intelligent electric meters connected under each phase
Box unit；
The fourth stage-ammeter connects several ammeters under each intelligent electric meter box unit.
If obtaining connection relationship (the first connection relationship), each phase of each feeder pillar between low-tension transformer and feeder pillar
Lower connected intelligent electric meter box unit (separate information), then have the connection relationship (between intelligent electric meter box unit and ammeter
Two connection relationships).Then the first connection relationship, separate information and the second connection relationship are integrated, then low-voltage distribution can be obtained
The whole network topological structure in platform area.
In the following, by, to the sequence of the first connection relationship, introducing how to obtain the second connection relationship, phase from the second connection relationship
Other information and the first connection relationship.
One, the second connection relationship (connection relationship between intelligent electric meter box unit and ammeter):
In one example, intelligent electric meter box unit can store the ammeter connecting with itself, therefore, the second connection relationship phase
To being easier to get.Fig. 5 is referred to, can be obtained by the identification device (in MCU) being mounted in intelligent electric meter box unit
The second connection relationship that intelligent electric meter box unit is stored, and uploading (can be by MCU control carrier communication module or radio communication mold
Block uploads) MCU into intelligent distribution transformer terminals.
Communication network shown in fig. 5 can are as follows: carrier communication network, cordless communication network or hybrid communication network.
In another example, it can be communicated between intelligent electric meter box unit and the ammeter being connected, by communicating skill
Art can determine which ammeter is connected with intelligent electric meter box unit, then the second connection relationship can be equally got, by being mounted on intelligence
Can the identification device (in MCU) in ammeter box unit be uploaded to the MCU in intelligent distribution transformer terminals.
Two, separate information (the intelligent electric meter box unit connected under each phase of feeder pillar):
Separate information is obtained based on the characteristics of power carrier signal.
Power carrier (Power line Communication, PLC), is the distinctive communication mode of electric system, benefit
With existing power line, analog or digital signal is carried out by high-speed transfer by carrier system.Electric power carrier communication technology does not need
Again network is set up, as long as live wire, can be carried out data transmitting.
Present invention take advantage of that power carrier signal following features:
1, general power carrier signal can only be transmitted in single-phase electricity line.
2, the intensity sharp-decay of power carrier signal when passing through physical connection branch node (namely identification device), from
And it can signal-to-noise ratio degradation.
Fig. 6 is referred to, the MCU being installed in feeder pillar has carried out following operation when obtaining separate information:
S61, control carrier communication module send the interrogation signal of generation in ABC three-phase respectively, alternatively, controlling the carrier wave
Communication module forwards interrogation signal in ABC three-phase respectively；
Since power carrier signal can only be transmitted in single-phase electricity line, then any separate intelligent electric meter box unit is in
Other separate interrogation signals can not be received and give response, feed back answer signal.
For example, the interrogation signal that feeder pillar is sent in A phase can not be in the intelligent electric meter box unit of B phase and C phase
It receives.Refer to Fig. 7, it is assumed that feeder pillar M sends or forwarded interrogation signal in A phase, and has received intelligent electric meter box unit
The answer signal of d1-d4 then can determine that intelligent electric meter box unit d1-d4 hangs over A phase.
It should be noted that intelligent electric meter box unit d1-d4 may not be connected under feeder pillar M, this is because feeder pillar M has
It may be relay station, can receive the answer signal being connected under the A phase of other feeder pillars (such as feeder pillar N).
It should also be noted that, power line carrier signal should include the mark (such as ID number, address) of sender, connect in this way
Debit just can determine specifically which equipment has sent power line carrier signal.
S62, basis determine branch in the signal-to-noise ratio of answer signal receiving, from intelligent electric meter box unit that respectively connects
The intelligent electric meter box unit that each phase of case is connected, obtains separate information.
Specifically, above-mentioned separate information includes the intelligent electric meter box unit that feeder pillar is connected in each phase.
By taking feeder pillar M as an example, separate information includes the intelligent electric meter box unit that A, B, C three-phase are separately connected.
The intelligent electric meter box unit for how determining that each phase of feeder pillar is connected according to signal-to-noise ratio is described below.
Aforementioned to be referred to, when passing through physical connection branch node (namely identification device), the intensity of power carrier signal is anxious
Play decaying, thus can signal-to-noise ratio degradation.Still by taking Fig. 7 as an example, the answer signal 1 of intelligent electric meter box unit d1, which can be directly to, to be reached
Feeder pillar M, and the answer signal 3 of Intelligent ammeter box d3 must just reach feeder pillar M after feeder pillar N.Then according to power carrier
The characteristic of signal, the signal-to-noise ratio of answer signal 3 obviously will be lower than answer signal 1.And if answer signal 3 experienced a knowledge incessantly
Other device just reaches feeder pillar M, then its signal-to-noise ratio can be even lower.
Therefore, it can will be divided at least two grades by descending in the signal-to-noise ratio of each answer signal for connecting and receiving,
Bigger grade, and signal-to-noise ratio is bigger, then intelligent electric meter box unit corresponding to the maximum answer signal of grade can determine that for this point
Branch case is connected directly.
Still by taking Fig. 7 as an example, it is assumed that feeder pillar M has received answer signal 1-4, wherein answer signal 1 and 2 belongs to grade
1, answer signal 3 and 4 belongs to grade 2, then can determine that answer intelligent electric meter box unit d1 and d2 corresponding to signal 1 and 2 be located at point
The A phase of branch case M.
S63, the separate information that itself is sent to the MCU being installed in intelligent distribution transformer terminals.
Three, the first connection relationship (connection relationship between low-tension transformer and feeder pillar)
In one example, the connection relationship between low-tension transformer and feeder pillar (the first connection relationship) and separate letter
Breath, can also be used the characteristic of power carrier signal foregoing description to obtain.

S81, control carrier communication module send interrogation signal；
S82, control carrier communication module receive the answer signal of multiple equipment feedback.
Since the level that intelligent distribution transformer terminals are in is higher, the interrogation signal sent can arrive each feeder pillar, each feeder pillar
Interrogation signal can be issued to each intelligent electric meter box unit again, then received answer signal may be from feeder pillar and intelligence electricity
Electricity box unit.
S83, signal-to-noise ratio is met to equipment corresponding to the answer signal of preset condition it is determined as feeder pillar, obtains the first company
Connect relationship.
Aforementioned to be referred to, when passing through physical connection branch node (namely identification device), the intensity of power carrier signal is anxious
Play decaying, thus can signal-to-noise ratio degradation.
By taking Fig. 9 as an example, it is whole that the answer signal 1 of intelligent electric meter box unit d1 must just reach intelligent distribution transforming after feeder pillar M
End, and 5 phase of answer signal of feeder pillar N directly reaches intelligent distribution transformer terminals.Then according to the characteristic of power carrier signal, response letter
Numbers 5 signal-to-noise ratio is obviously higher than answer signal 1.And if answer signal 1 experienced an identification device incessantly and just reach intelligence
Distribution transformer terminals, then its signal-to-noise ratio can be even lower.
Therefore, signal-to-noise ratio can be met to equipment corresponding to the answer signal of preset condition and is determined as feeder pillar, thus
To the first connection relationship.
Above-mentioned preset condition can include: signal-to-noise ratio is more than or not less than snr threshold, alternatively, signal-to-noise ratio falls in preset areas
Between.Snr threshold or pre-set interval can determine according to actual needs and flexibly.
Still by taking Fig. 9 as an example, it is assumed that the identification device in intelligent distribution transformer terminals has received answer signal 1 and 5, wherein answers
The signal-to-noise ratio for answering signal 5 is greater than snr threshold, and the signal-to-noise ratio of answer signal 1 is less than snr threshold, then can determine that response is believed
Number 5 corresponding equipment are feeder pillar.
Later, the MCU being installed in intelligent distribution transformer terminals can connect according to the first connection relationship of acquisition, separate information and second
Relationship is connect, integration obtains the network topology structure of low-voltage power distribution station area.
In addition, the MCU being installed in the intelligent distribution transformer terminals also can control wireless communication module by above-mentioned network topology
