Description
Technical field
It is especially a kind of based on block chain technology the present invention relates to distributed energy transaction communications platform and communication means
The building method of distributed energy transaction communications platform, communication means and communications platform.
Background technique
With the rise of energy internet and the lasting construction of smart grid, distribution scale constantly expands, distribution network systems
Function is increasing.Traditional distribution network systems are merely responsible for the distribution of electric energy, and future is stepped up electricity collection, transmission, storage etc.
Function is realized and directly carries out two-way interactive with user.Under such technical background, along with distributed energy, electric car
Deng access power grid, a large amount of consumers in power grid translate into prosumer, promote the free bilateral transaction to form electric power.Due to area
The decentralization of block chain technology, the transparency, fairness are consistent with the thought of energy internet, and academia trades in the energy and leads
The application of block chain technology is conducted extensive research in domain.
Block chain network is the P2P network an of decentralization, and central server is not present.Each of network node
It is assembled with unified block chain client and DApp server-side, i.e., is used as client and server-side simultaneously.Compared to more traditional
For adapted telecommunication network, block chain network has the advantage that 1) Distributed Storage: block chain is using distribution
The technology of formula storage, therefore the database of centralization is not present；2) information transparency: any user can be by having inquiry
Data in the querying node block chain of function；3) high degree of autonomy: block chain with consensus specification and agreement, it is automatic,
Safely exchange data；4) data can not distort: data in each block i.e. quilt after hash algorithm calculates and generates cryptographic Hash
Otherwise secure storage is invalid to the modification of block chain data except the system that non-concurrent control is more than 51% calculates power.
In the application of energy transaction, block chain needs to obtain data by internet, but according to document [Narayan
Prusty. block chain project development guide [M], China Machine Press, 2018] it is described, due to by block chain technology and common recognition
The limitation of algorithm, the data exception that block chain obtains external network are complicated.Existing research is most of to use third party database
Oraclize service come make block chain obtain the data from internet, but realize process have certain difficulty, it is necessary
It arranges in pairs or groups and uses with ether mill intelligence contract, higher requirement is encoded with to intelligent contract, increases the development difficulty of developer.
And it needs data delivering third party database using Oraclize service, there is the hidden danger for causing information leakage.About block
The specific method of chain and internet data communication, lacks correlative study, in addition to this above method, does not find the phase published
Close documents and materials.
Since in the application scenarios that distributed energy is traded, block chain needs to obtain a large amount of prosumer's information, above-mentioned
Communication means is needed by the third party database on internet, has unstability at the reliable aspect of transmission massive information,
Therefore need to seek a kind of effective method to realize multi-information fusion communication means.
Summary of the invention
For the above demand, the present invention provides a kind of distributed energy transaction communications platform based on block chain technology,
The building method of communication means and the communications platform realizes the communication of prosumer's information in distributed energy trade market
Transmission achievees the effect that multi-information fusion communicates, and the construction for distributed energy trade market communication network provides information support.
The technical solution of the present invention is as follows:
A kind of distributed energy transaction communications platform based on block chain technology, the layer to interoperate including three: hardware layer,
Application layer and block link layer, the hardware layer include hair/electrical equipment, intelligent electric meter and the intelligent terminal of user, the intelligence
Ammeter is mounted in hair/electrical equipment, and is connected with intelligent terminal, for measuring and transmitting information about power, the intelligent terminal
It is the physical support of application layer and block link layer；The block link layer includes intelligent contract, and the intelligence contract is digital form
Trading rules, reception, operation, storage and the feedback function of Transaction Information are carried, for realizing energy distributed transaction；It is described
Application layer is the Distributed Application being made of web front-end, the rear end js and the rear end Python, for realizing hardware layer, application layer and
Block link layer is in communication with each other, and the web front-end shows the interactive interface of user and transaction system by intelligent terminal, for connecing
That receives user's input declares information and Transaction Information, and information and Transaction Information are declared from web front-end reading in the rear end js, and remote
Journey calls intelligent contract, input to declare information and Transaction Information, and information about power is read from intelligent electric meter in the rear end Python, and
Far call intelligence contract, input information about power.
In block link layer, it is based on the public block chain development platform in ether mill, using the primary data storage in ether mill, network
Communication means and common recognition algorithm, use ether mill client geth as block chain user node, use Solidity programming language
Speech writes intelligent contract.
Web front-end is developed using html programming language, the rear end js is developed using JavaScript programming language, uses
Python programming language develops the rear end Python, and the rear end js is logical by the jQuery frame and web front-end of JavaScript
Letter.
The rear end js and the rear end Python use far call agreement JSON-RPC to call intelligent contract.
Hair/electrical equipment of the user does not limit user as monistic producers or consumers, allows user free
Convert the identity of prosumer.
The intelligent electric meter is that DTZY208 type three-phase and four-line takes control intelligent electric meter, has 1 infrared communication interface, 1
RS485 communication interface and 1 carrier communication interface, the intelligent electric meter turn the converter of USB interface by RS485, with intelligence
Terminal connection, intelligent electric meter follow DL/T645-2007 communication protocol.
A kind of building method of the distributed energy transaction communications platform based on block chain technology, comprising the following steps:
S1: building hardware layer, and intelligent electric meter is mounted in hair/electrical equipment of user, and has been connect with intelligent terminal
Come；
S2: building block link layer, installs and runs ether mill client geth, the privately owned chain in ether mill is built, according to specific
Market trading facility write intelligent contract, intelligent contract is deployed in ether mill network using ether mill client geth；
S3: building application layer, and intelligent contract original code is compiled as web3 interface code, is programmed into the rear end js and Python
Rear end, develops web front-end using html programming language, develops the rear end js using JavaScript programming language, uses Python
