Distributed power equipment information acquisition system and method based on blockchain

Abstract

The invention discloses a distributed power equipment information acquisition system based on a blockchain, which comprises a plurality of acquisition stations. The acquisition stations are respectively and correspondingly arranged in acquisition regions partitioned according to geographic positions; each acquisition station is connected with a sensor, the acquisition station and the sensor are arranged in the same acquisition region, and the sensor acquires power equipment information data in the corresponding acquisition region; each acquisition station is provided with a storage device andhas a key corresponding to the acquisition station, the key comprises a private key and a public key uniquely corresponding to the private key, and the public key is transmitted to all the acquisitionstations; the acquisition stations carry out encryption on the power equipment information data by adopting the corresponding private keys to form digital signatures, and store the received data anddigital signatures in the storage devices in a block form; and other acquisition stations carry out decryption on the digital signatures on the basis of the public key, carry out verification on the received data, and store the data passing verification into the corresponding storage devices in a block form.

Description

technical field [0001] The invention relates to an information collection system and method, in particular to a power equipment information collection system and method. Background technique [0002] As the application of the power Internet of Things in the smart grid becomes more and more diverse and the coverage becomes wider and wider, the data and information collected by power sensing devices increase explosively. At the same time, the number of service devices (such as routers and converters) Also growing exponentially. The traditional power industry often adopts centralized data collection methods for data collection. In centralized data collection, a unified data center processes and stores the collected data. The explosive growth of data volume greatly increases the processing burden of the data center. In addition, since the centralized processing device management adopts a pyramidal hierarchical management structure, when the management device fails, it will ofte...

Problems solved by technology

[0004] One of the purposes of the present invention is to provide a blockchain-based distributed power equipment information collection system, which proposes a decentralized distributed power system based on blockchain (Blockchain) technology The equipment information collection method is to set up several collection stations and disperse the information processing to each collection station, so that each collection station is set as a processing module, so that it is responsible for the information collection in each area, thus solving the problem of excessive collection of information Big problem; at the same time, because different collection stations are used as different processing modules to store the collected data in the form of blockchain, several processing modules jointly maintain blockchain data, that is to say, once a certain processing module fails , other processing modules are still able to continue data maintenance, thereby reducing the impact of equipment failures
