The embodiment automatically collects the power generation data of the electric meter by designing a special trusted device, and calculates the target issuing number of the green power certificate according to the power generation data. In addition, in the embodiment, the blockchain is used as a multi-party collaborative public facility, the device may send a green power certificate issue request to the blockchain after calculating the target issue number, the blockchain authenticates the device through a user account contract after receiving the green power certificate issue request, and automatically issues the green power certificate on the chain through operation of an asset issue contract after the authentication is passed.

The embodiment provides a green power certificate issuing system based on a blockchain, which comprises equipment and the blockchain. The system directly obtains reliable power generation data from an ammeter through equipment, automatically calculates the number of green power certificates according to the power generation data, and then performs equipment authentication through a block chain and automatically issues the green power certificates to a user account. The process of manually accounting the power generation data is avoided, the green power certificate issuing efficiency is improved, and the reliability and the credibility of the green power certificate issuing process can be guaranteed based on the block chain technology.
The second embodiment of the green power certificate issuing system based on the blockchain provided by the present application is described in detail below, and the second embodiment is implemented based on the first embodiment and is expanded to a certain extent on the basis of the first embodiment.
The embodiment includes a device, a block chain, and an issuing entity, which are described below.
First, the process flow of the equipment
1. The device reads the electric meter in a non-contact mode to obtain power generation data, and calculates the target issuing number of the green power certificate according to the power generation data.
For safety reasons, direct reading of the power generation data of the electricity meter is generally not allowed, so the embodiment reads the electricity meter in a non-contact manner. In practical application, the non-contact mode may specifically be infrared image recognition, and the infrared image of the electric meter is obtained first, and then character recognition is performed on the infrared image to obtain power generation data.
The target issuing quantity of the green power certificate is actually calculated according to the power generation quantity of the electric meter in a period of time and the power generation quantity standard of a single green power certificate. Therefore, the process of calculating the target issue number of the green power certificates according to the power generation data specifically includes: reading historical power generation data, calculating a power generation data difference value according to the power generation data and the historical power generation data, and calculating the target issuing quantity of the green power certificates according to the power generation data difference value and the power generation data standard of a single green power certificate, wherein the historical power generation data is the power generation data when the green power certificate is sent to the blockchain last time. In practical applications, the power generation data standard of the single green power certificate may be 1 Mwh.
2. The equipment generates a green power certificate issuing request carrying a target issuing quantity, and sends the request to the block chain to trigger the issuing process of the green power certificate.
In practical applications, data interaction between a device and a block chain needs to be asymmetrically encrypted. Specifically, the device and the blockchain negotiate in advance, and after the negotiation is completed, the device holds the private key and the blockchain holds the public key. The device signs the green power certificate issuance request with the private key after generating it, and then sends the signed green power certificate issuance request to the blockchain. And the block chain checks the signed green power certificate issuing request by using the public key, and if the check shows that the message comes from the trusted equipment, the block chain continues to process the green power certificate issuing request, otherwise, the block chain discards the green power certificate issuing request.
For the triggering mode of the device triggering the green power certificate issuing process, the present embodiment provides the following two implementation modes:
the implementation mode is as follows: the equipment continuously monitors the power generation data of the electric meter, and when the power generation data is full of 1 green power certificate, a green power certificate issuing process is triggered once.
The implementation mode two is as follows: the method comprises the steps that collection frequency or collection time is preset, equipment periodically collects power generation data of an electric meter, then a target issuing number is calculated to trigger a green power certificate issuing process, or the equipment regularly collects the power generation data of the electric meter according to the preset time, and then the target issuing number is calculated to trigger the green power certificate issuing process.
Second, processing flow of block chain
The block chain receives a green power certificate issuing request sent by equipment, authenticates the equipment and a user account according to a user account contract input in advance, determines the user account bound with the equipment if the authentication is passed, and issues a target issuing quantity of green power certificates to the user account according to an asset issuing contract.
The block chain is considered to be capable of carrying out safe equipment authentication through asymmetric encryption, and an intelligent contract interface of digital assets is supported, so that controllable green power certificate data issuing can be realized, and manual intervention is reduced.
Thirdly, exception handling flow of issuing unit
1. When the device is abnormal, the issuing unit can log off or terminate the certificate issuing authority of the device in the block chain.
2. If the green power certificate issuing process is abnormal, the issuing unit can log off the green power certificate in the block chain.
It can be seen that the green power certificate issuing system based on the blockchain provided by the present embodiment includes at least the following advantages:
1. the automatic reading of the equipment is utilized, the power generation data accounting process is automated, manual auditing is avoided, and the efficiency is improved.
2. By a configurable time period, the frequency of green power certificate issuance can be adjusted.
3. And equipment management and green power certificate recording are performed by using the block chain, so that the reliability and credibility of the green power certificate issuing process are guaranteed.
