In order to make the objects, technical solutions and advantages of the present invention more apparent, the following description is made by way of specific embodiments with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a distributed energy transaction system according to an embodiment of the present invention. As shown in fig. 1, the distributed energy trading system includes a server node, a smart meter node, and a user. The server nodes and the intelligent electric meter nodes form a block chain network, safe and reliable storage and transmission of electric power transaction data in the distributed energy transaction system are achieved, and then convenient and efficient electric power transaction and settlement are achieved.
In some embodiments, the number of server nodes may be multiple, and for example, the server nodes may be the first server node 111, the second server node 112, and the third server node 113 shown in fig. 1.
In some embodiments, the smart meter node may be a smart meter on the supply side or a smart meter on the load side. For example, the smart meter nodes may be a first smart meter node 121, a second smart meter node 122, and a third smart meter node 123 as shown in fig. 1.
In some embodiments, the user may be a donor-side user. For example, the user may be a coal fired thermal power plant, a natural gas power plant, a wind power plant, a photovoltaic power plant, and the like. Alternatively, the user may also be an energy storage device, a distributed wind and solar power generation user, or the like. For example, the user 131 may be a photovoltaic power generation user in a household unit. Customer 132 may be a coal fired power plant.
In another embodiment, the user may also be a load-side user. Illustratively, the user may be a cell resident, a factory, various high energy-consuming power equipment, or the like. Illustratively, user 133 may be a subscriber to a cell.
As a possible implementation manner, the distributed energy transaction system may store the electric power transaction data detected by the smart meter node periodically and commonly. Or when the distributed energy transaction system receives the trigger information, the power transaction data detected by the intelligent electric meter nodes are subjected to consensus storage.
In order to achieve transparency of settlement of electric power transactions, electric power consumers need to access data in the blockchain system. In the data access process, the power consumer communicates with a server node in the blockchain system through the internet, and after receiving a communication request of the power consumer, the server node needs to communicate with a blockchain module in the terminal ammeter to acquire the latest data information and send the latest data information to the power consumer.
On the one hand, the electric power transaction data comprises various real-time metering data such as real-time load, voltage, current, frequency, load rate, power factors, voltage unbalance, harmonic conditions and the like, and the electric power transaction data is various in types and large in data volume. On the other hand, the number of the users accessing the distributed energy trading system at the same time is larger due to the larger number of the power users. Therefore, during the process of accessing the latest power transaction data by a large-scale user, a large data transmission consumption may be caused in the blockchain system, which is not favorable for the stability of data transmission in the blockchain system.
To solve the above technical problem, as shown in fig. 2, an embodiment of the present invention provides a data transmission method for a distributed energy transaction system. The data transmission method is applied to a distributed energy transaction system as shown in fig. 1, the distributed energy transaction system comprises a server node and a smart meter node, and the data transmission method comprises steps S201-S203.
S201, receiving a data request sent by a user terminal.
In some embodiments, the user terminal may be a cell phone, a computer, or a PDA.
In the embodiment of the application, the data request is used for requesting the electric power transaction data of the user.
The electric power transaction data comprises real-time metering data and electric power transaction results. The real-time metering data is data obtained by real-time metering of the intelligent electric meter nodes. And calculating the electric power transaction result for the intelligent electric meter node to obtain the data to be transacted and the transacted data of the user corresponding to the intelligent electric meter node.
In some embodiments, the data request may include a start time, an end time, and a type of the power transaction data.
In other embodiments, the data request may also include identification information of the user or identification information of the user terminal. Thus, the server node may determine power transaction data corresponding to the user based on the identification information of the user. Or the server node can also determine whether the user terminal is legal or not based on the identification information of the user terminal, thereby improving the data security.
In other embodiments, the data request may further include identification information of the intelligent electricity meter node corresponding to the user or the user terminal.
S202, if a data request sent by the user terminal is received, whether the user terminal and the intelligent electric meter node are in a connection state or not is judged.
In some embodiments, when the user terminal and the smart meter node are in a connected state, the user terminal and the smart meter node may be connected through a connection channel. Illustratively, the connection channel may be one of: bluetooth, wiFi and USB.
As a possible implementation manner, the server node may query, through a registration table in a memory of the server node, a status identifier in the registration table, where the status identifier is used to indicate whether the user terminal and the smart meter node are in a connected state. And if the state identifier indicates that the user terminal and the intelligent electric meter node are in the connection state, determining that the user terminal and the intelligent electric meter node are in the connection state. And if the state identification indicates that the user terminal and the intelligent electric meter node are in the unconnected state, determining that the user terminal and the intelligent electric meter node are not in the unconnected state.
As another possible implementation manner, the server node may send, to the smart meter node, query information indicating whether the user terminal and the smart meter node are determined to be in a connected state. And after receiving the query information, the intelligent electric meter node determines whether the user terminal and the intelligent electric meter node are in a connection state, and sends a determination result to the server node. Therefore, the server node finishes the process of judging whether the user terminal and the intelligent electric meter node are in the connection state.
For example, as shown in fig. 3, the server node may determine whether the user terminal and the smart meter node are in a connected state through steps S2021-S2024.
S2021, the server node sends a connection state judgment instruction to the intelligent electric meter node.
Wherein, the connection state judgment indication comprises a user terminal identification.
And S2022, generating a connection state judgment response by the intelligent electric meter node based on the connection state judgment instruction.
And the connection state judgment response comprises a step of indicating whether the user terminal and the intelligent electric meter node are in a connection state or not.
S2023, the intelligent ammeter node sends a connection state judgment response to the server node.
S2024, the server node judges whether the response confirms that the user terminal and the intelligent electric meter node are in the connection state or not based on the connection state.
Therefore, the server node can be communicated with the intelligent electric meter node to determine whether the user terminal and the intelligent electric meter node are in the connection state or not, so that the determined connection state is more accurate, the success rate of the intelligent electric meter node for sending electric power transaction data to the user terminal is improved, and the success rate of the user terminal for obtaining the electric power transaction data is improved.
As another possible implementation manner, the server node may further send, to the user terminal, query information for indicating whether the user terminal and the smart meter node are determined to be in a connected state. And after receiving the query information, the user terminal determines whether the user terminal is in a connection state with the intelligent electric meter node, and sends a determination result to the server node. Therefore, the server node completes the judgment process of whether the user terminal and the intelligent electric meter node are in the connection state or not.
As another possible implementation manner, the server node may also send query information for indicating whether the user terminal and the smart meter node are determined to be in a connected state to the user terminal and the smart meter node at the same time. And when the determination result of the user terminal and the determination result of the intelligent electric meter node are both in a connection state, determining that the user terminal and the intelligent electric meter node are in the connection state.
S203, if the user terminal is connected with the intelligent electric meter node, sending first indication information to the intelligent electric meter node.
In the embodiment of the application, the first indication information is used for indicating the smart meter node to send the power transaction data to the user terminal.
In some embodiments, the first indication information may include a user terminal identification and identification information of the power transaction data.
The invention provides a data transmission method of a distributed energy transaction system, wherein when a user terminal requests electric power transaction data, a server node judges whether the user terminal and an intelligent electric meter node are in a connected state or not, and when the user terminal and the intelligent electric meter node are in the connected state, the server node indicates the intelligent electric meter node to directly send the electric power transaction data to the user terminal. Compared with the technical scheme that the server node acquires the electric power transaction data from the intelligent electric meter node and then sends the electric power transaction data to the user terminal, the method and the system can indicate the intelligent electric meter node to directly send the electric power transaction data to the user terminal when the user terminal is connected with the intelligent electric meter node, reduce the data volume of a data transmission process between the server node and the intelligent electric meter node in the distributed energy transaction system, improve the data transmission speed of the distributed energy transaction system, and further improve the stability of the distributed energy transaction system.
Optionally, as shown in fig. 4, the data transmission method of the distributed energy trading system according to the embodiment of the present invention further includes step S204.
And S204, if the user terminal is not in a connection state with the intelligent electric meter node, sending second indication information to the user terminal.
In the embodiment of the application, the second indication information is used for indicating the user terminal to select the equipment node for acquiring the electric power transaction data. The equipment nodes comprise a server node and a smart meter node.
Therefore, the embodiment of the invention can provide the user terminal with the selection opportunity of the equipment node for acquiring the electric power transaction data, and improves the convenience of the user terminal for accessing the electric power transaction data.
Optionally, in the data transmission method of the distributed energy transaction system provided in the embodiment of the present invention, before determining whether the user terminal and the node of the smart meter are in the connection state, the prediction apparatus may further determine whether the user terminal is legal, and when the user terminal is a legal terminal, continue to determine the connection state between the user terminal and the smart meter. Therefore, the method and the device can judge the legality of the user before judging the connection state between the user terminal and the intelligent electric meter, and improve the safety in the data transmission process.
Illustratively, as shown in fig. 5, the predicting means may determine the validity of the user terminal based on steps S301-S304.
S301, inquiring the registration table, and determining whether the user terminal identification exists in the registration table.
S302, if yes, determining that the user terminal is a legal terminal, and executing a step of judging whether the user terminal and the intelligent electric meter node are in a connection state.

It is understood that the user may perform active registration with the user terminal, and may perform passive registration based on the third indication information.
Illustratively, as shown in FIG. 6, the registration process of the user terminal may be implemented based on steps S401-S402.
