Problems solved by technology

[0002] Traditional metrological verification certificates are generally generated by a centralized organization, which cannot solve the possibility that the certificate data and the certificate approval process are artificially tampered with during the certificate generation process. After the certificate is generated, it is usually saved to a centralized file server. When the user When checking the certificate with the file server, the transfer of the certificate file involves network transmission and human operation, and the authenticity of the certificate file viewed by the user is also difficult to guarantee. This situation makes the verification certificate not convincing as the quality certificate of the measurement equipment;

Embodiment 1

[0036] Such as figure 1 Shown: the present invention is based on the generation method of the metering equipment verification certificate of block chain technology, comprises the following steps:

[0037] Step1: Assemble the certificate data;

[0038] Step2: Verify the validity of the data;

[0039] Step3: Complete the automatic certificate approval;

[0040] Step4: Generate a unique number for the certificate;

[0041] Step5: Sign the certificate;

[0042] Step6: Generate a certificate;

[0043] Step7: Save the summary value of the certificate file to the blockchain through the data storage smart contract.

[0044] In Step1, the certificate data is assembled, including the metering equipment asset information table, the metering equipment random inspection result table, the metering equipment full inspection result table, and the metering equipment basic error table. The key information for generating the verification certificate is extracted from the above database tabl...

Embodiment 2

[0074] Such as figure 2 Shown: a method for checking the verification certificate of metering equipment based on blockchain technology, including the following steps:

[0075] Step1: Obtain the certificate file;

[0076] Step2: Calculate the certificate summary;

[0077] Step3: Compare the summary value with the summary value of the certificate file stored in the blockchain;

[0078] Step4: The digest values ​​of the two are the same, which proves that the certificate file has not been tampered with, and the certificate file is authentic and credible.

[0079] Step5: After checking and comparing the digests on the chain, if the digest values ​​of the two are different, the certificate file has been tampered with.

[0080] When the user needs to verify the authenticity of the certificate file, the digest value of the local certificate file can be calculated, and the digest value is compared with the digest value of the certificate file stored in the blockchain. If the diges...

Embodiment 3

[0088] At present, a provincial metrology center participates in the key technology research of the NQI platform. Based on the network's provincial chain, it carries out the construction of trusted applications related to metrology, and uses blockchain technology to generate reliable Trusted metering equipment verification certificate, and the certificate summary value is stored in the blockchain network, and users can check the metering equipment verification certificate on the blockchain through the energy meter quality data query transparent service of the NQI platform;

[0089] The blockchain network relies on a network provincial slave chain in the "one master and two sides multiple slaves" architecture of the State Grid blockchain to provide a multi-party operating environment for the alliance blockchain, and to verify the validity of the data contract and automatically approve the contract for the certificate , the certificate unique number generation contract, the certi...

Abstract

The invention discloses a metering equipment verification certificate generating and checking methods based on the block chain technology, and relates to the technical field of block chains. The metering equipment verification certificate generating method based on the block chain technology comprises the following steps: Step 1, carrying out certificate data assembly; Step 2, verifying the validity of the data; Step 3, completing automatic approval of the certificate; Step 4, generating a unique number of the certificate; Step 5, carrying out certificate signature; Step 6, generating the certificate; and Step 7: storing the abstract value of the certificate file to the block chain through a data storage smart contract. According to the metering equipment verification certificate generating and checking methods based on the block chain technology, the credibility of the metering equipment verification certificate generating and checking process is ensured by utilizing the technologies such as the intelligent contract, the oracle machine and the data storage in the block chain, and the trust of the public to the quality of metering equipment is improved.
