Problems solved by technology

However, there are still two problems in the direct application of blockchain technology to the storage of power metering data: First, the blockchain can verify the authenticity of the data uploaded to the blockchain and avoid tampering, but it cannot guarantee Data has not been tampered with before being uploaded to the blockchain
The second is that uploading data to the blockchain needs to consume funds. Increasing the frequency of uploading the blockchain can increase the difficulty of data tampering, thereby improving the credibility of the data, but at the same time it will also bring higher capital costs
Its technical solution realizes the application of blockchain with the support of embedded systems, but the blockchain it establishes is a private blockchain, and its credibility is not high
Thereby its technical scheme can't solve above-mentioned two problems

Embodiment 1

[0033] An anti-tampering method for smart energy meters based on block chain technology, please refer to the attached figure 1 , this method includes the following steps:

[0034] Step A01) Read the metering reading in the first cycle, and write the metering reading into a designated buffer area.

[0035] Step A02) Build the data preparation layer 20, the data preparation layer 20 takes out the metering readings from the buffer area in the first cycle, and establishes the storage data 21, and the storage data 21 includes the metering readings, time stamp, electric energy meter 90 serial number and designated storage address, metering readings Make the length reach the preset value by padding with zeros.

[0036] Preferably, in step A01) of the present embodiment, the voltmeter reading of the electric energy meter 90 can be read in the fifth cycle, and stored in the buffer 10, until the first cycle is reached, and the power consumption reading and power of the smart electric e...

Embodiment 2

[0057] An anti-tampering method for a smart energy meter based on blockchain technology. Compared with the first embodiment, which will occupy the computing power of the smart energy meter 90, this embodiment specially builds a support machine 80 to complete the storage of the saved data 21. The established proof of work reduces the pressure on the computing power of the smart energy meter 90. Please refer to the attached Figure 5 , the present embodiment constructs a supporting machine 80, which is connected to several electric energy meters 90 and the electric power metering and billing center 70 in communication, and the supporting machine 80 receives a matching number set, and finds an exhaustive list for each matching number in the matching number set The hash value extracted together with the exhaustive number and the matching number meets the preset proof-of-work conditions, and the found exhaustive number and matching number are associated and stored. When the energy ...

Embodiment 3

[0084] An anti-tampering method for a smart energy meter based on blockchain technology. This embodiment provides an alternative to a relay meter on the basis of Embodiment 2. For this example, please refer to the attached Figure 8 , the method that the energy meter 90 asks for matching numbers and corresponding exhaustive numbers includes: step E01) the energy meter 90 agrees with the support machine 80 on a binary function; step E02) the support machine 80 associates an identification number with each matching number, and The matching number and the identification number are disclosed; step E03) the electric energy meter 90 extracts the hash value obtained from the metering reading and the time stamp, finds the identification number associated with the matching data that is identical to the N bits at the end of the hash value, and records it as the target identification number; step E04) Select the electric energy meter 90 other than itself as the relay table, the relay tab...

Abstract

The invention relates to the technical field of blockchains, in particular to a blockchain technology-based intelligent electric energy meter tamper-proofing method. The method comprises the following steps: reading metering readings in a first period; constructing a data preparation layer, taking out the metering readings from a cache region in the first period, and establishing disk storage data; establishing a storage agent layer, and periodically providing a preset number of random codes for the data preparation layer, wherein the storage agent layer receives the disk storage data and stores the disk storage data into a storage block address corresponding to a specified storage address; constructing an evidence storage fixing layer, including the disk storage data newly stored in the storage region into a to-be-fixed set in a second period, and extracting a hash value from a time set and a hash set together to serve as a fixed hash value, and uploading the fixed hash value to a blockchain for storage; uploading the metering readings in the latest disk storage data to an electric power metering and billing center in a third period. The method has the beneficial effect that the credibility of measurement data is improved by periodically uploading the measurement data to blockchains for storage.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a tamper-proof method for smart electric energy meters based on block chain technology. Background technique [0002] With the rapid development of my country's economy, the demand for electricity in all walks of life is increasing. The accurate collection and measurement of power consumption data involves the direct interests of power supply companies and power users, and is an important link to ensure the healthy operation of the power supply market. In the power system, there is not only the need to measure the amount of electricity consumed by users, but also to measure the power factor of the electricity consumed by users. The low power factor of user loads will put pressure on the operation of the power grid and increase the cost of power grid operation. Therefore, users with large electricity consumption, such as factories, are usually required to install capacitors...
