As shown in figure 1, an embodiment provides a kind of power information acquisition system, including power information harvester 100
With power distribution automation main station 200.Wherein, power distribution automation main station 200 is the core of electrical power distribution automatization system, main realization
Electric distribution network data collection and the expanded function such as the basic functions such as monitoring and Topology Analysis of Power Distribution Network application.Power information collection dress
Put 100 and be arranged in terminal device 110 side, and communicated by mobile communications network with power distribution automation main station 200.Electricity consumption
Information collecting device 100 is used for the power information of acquisition terminal equipment 110, and passes through PLC repeated link and mobile communications network
Transmit to power distribution automation main station 200.Wherein, mobile communications network is, for example, GPRS network, LTE (Long Term
Evolution, Long Term Evolution) network, CDMA (Code Division Multiple Access, CDMA) network or its
Its type.
Power information harvester 100 includes terminal device 110, local repeater 120 and remote repeater 130.Wherein,
Terminal device 110 is used for gathering power information, and it can be big customer's negative control terminal, resident's power information acquisition terminal
Deng.Terminal device 110 is connected with local repeater 120.Specifically, terminal device 110 and local repeater 120 pass through Ethernet
Connect.It is understood that can also be using other connected modes between terminal device 110 and local repeater 120.
Local repeater 120 is also communicated by power carrier communication technology with remote repeater 130.Therefore, locally
Repeater 120 and remote repeater 130 constitute above-mentioned PLC repeated link.Remote repeater 130 is additionally operable to by mobile logical
Communication network is communicated with power distribution automation main station 200.Therefore, in terminal device 110, local repeater 120, remote repeater
130th, a complete data transmission link can be set up between power distribution automation main station 200.Meanwhile, remote repeater 130 institute
The mobile communications network signal strength signal intensity of place position disclosure satisfy that is led to power distribution automation main station 200 by mobile communications network
The requirement of letter. in other words, the mobile communications network signal strength signal intensity of remote repeater 130 present position is more than given threshold, to protect
Card remote repeater 130 can carry out proper communication with power distribution automation main station 200 by mobile communications network.
Wherein, power carrier communication technology, i.e. PLC technology, is a kind of communication skill being carried out data transmission by power line
Art, it is by the use of existing electrical network as the Transfer Medium of signal so that electrical network can also carry out data while transmitting electric power
Communication.Power carrier communication technology plug and play, substantially increases production, work and life efficiency, saves to a great extent
Cable wiring manufacture cost, as long as all this technology can be used using the equipment of electric power, and also reliable and stable.Further, since terminal sets
Standby 110 communication speed is higher, and therefore power carrier communication technology adopts the bandwidth carrier technology of high speed, illustratively：Using 1～
The carrier frequency of 30MHz, transfer rate, between 1～200Mbps, adopts ripe DMT (Discrete Multi- simultaneously
Tone, discrete multitone, DMT) modulation system is such that it is able to avoid the occurrence of the communication blocking problem that single carrier wave may be disturbed.

A repeated link is established (i.e. by local repeater 120 between region and the stronger region of mobile communications network signal strength signal intensity
The PLC transmission link constituting with remote repeater 130), therefore in the mobile communications network signal of terminal device 110 present position
In the case that intensity is poor or this position do not have mobile communications network signal, power information can be passed through by terminal device 110
Local repeater 120 is sent to remote repeater 130, due to the mobile communications network signal of remote repeater 130 present position
Intensity disclosure satisfy that the requirement being communicated by mobile communications network, therefore remote repeater with power distribution automation main station 200
Power information finally can be uploaded to power distribution automation main station 200 by 130, thus solving mobile communications network to cover deficiency
Problem is so that be located at that mobile communications network signal strength signal intensity is weaker or the terminal device in region that do not have mobile communications network signal
110, remain able to keep the normal transmission of data with power distribution automation main station 200, also relieve simultaneously and terminal device 110 is pacified
The scope restrictive condition of holding position is such that it is able to the more preferable integrated planning scheme that must follow electric company.

In addition, the power supply of remote repeater 130 is to be provided with the second electricity in single-phase alternating current, and remote repeater 130
Source module (not shown).This second source module is suitable in remote repeater 130 respectively for being converted to single-phase alternating current
The power supply of module work, thus be powered to each module within remote repeater 130.
It is understood that the composition structure of remote repeater 130 is not limited to above-mentioned situation, as long as enabling to distribution certainly
The signal that Dong Hua main website 200 sends by power line transmission to local repeater 120, and can make local repeater 120 transmit
Signal power distribution automation main station 200 can be wirelessly transmitted to by mobile communications network.For example, if the second power carrier
There is inside communication module 131 termination power, then the second termination power 136 need not be set.
Each technical characteristic of embodiment described above can arbitrarily be combined, for making description succinct, not to above-mentioned reality
The all possible combination of each technical characteristic applied in example is all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all it is considered to be the scope of this specification record.
Embodiment described above only have expressed the several embodiments of the present invention, and its description is more concrete and detailed, but simultaneously
Can not therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
Say, without departing from the inventive concept of the premise, some deformation can also be made and improve, these broadly fall into the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be defined by claims.
