Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic inverter blockchain transformation, and specifically to a photovoltaic inverter blockchain transformation device based on RTU / DTU devices. Background Art

[0002] Blockchain is a new application mode of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, and encryption algorithms. This transformation device aims to intelligently upgrade photovoltaic inverters by integrating RTU (Remote Terminal Unit) / DTU (Data Transmission Unit) devices with blockchain technology. This upgrade not only improves the remote monitoring and management capabilities of photovoltaic inverters but also enhances the security and transparency of data through blockchain technology.

[0003] The defects of existing blockchain transformation devices are as follows: 1. Patent document CN113064675B discloses an inheritable blockchain lossless transformation method. "The present invention provides an inheritable blockchain lossless transformation method. The present invention conducts an inheritance-based transformation based on a consortium blockchain. On the one hand, it maximally reuses open-source code (including but not limited to node code and a complete software development kit with functions), reducing development costs; at the same time, all smart contracts that can run on the consortium blockchain can run on this system; in addition, due to a decentralized user authentication system based on the elliptic curve algorithm, users can easily use this system." However, the blockchain lossless transformation method in the prior art has technical problems of low reliability in the data collection process and low security protection effect in data management. 2. Patent document CN113888165A discloses a method, device, and storage medium for blockchain address transformation and identity authentication. "The present invention belongs to the technical field of computers, and particularly relates to a method, device, and storage medium for blockchain address transformation and identity authentication. The advantage of the present invention is that it ensures that users do not disclose their own information when registering an address, and only provide identity card information when identity verification is required (such as in cases of asset recovery, etc.), ensuring user privacy and security. On the other hand, the identity hash is obtained by performing N hash operations on the first random string, identity information, and private information, rather than directly using the identity card number for hash operation as in the conventional method, avoiding hackers using the coding rules of identity cards or collecting a large amount of identity card information for brute force cracking and corresponding it with the account address to obtain user identity information. The hashN operation is used to increase the cost of cracking address information and increase a certain cracking duration. The duration for obtaining the identity hash is set by setting N, so that hackers cannot attempt various combinations multiple times in a short period for brute force cracking." However, the method for blockchain address transformation and identity authentication in the prior art has technical problems of poor environmental adaptability and inability to stably run data transmission for a long time. 3. Patent document CN117640093A discloses a method, system, storage medium and computing device for blockchain digital signature transformation. "The present invention discloses a method, system, storage medium and computing device for blockchain digital signature transformation, including: the server counts the on-chain nodes and collects the public keys P of each node; the server sends a data on-chain request and generates a message push list M; the nodes sign the on-chain message with the public key to generate signature information S; the server generates an aggregated signature AggS through an algorithm using the signature information S, the public key information P, and the message list M; the server directly verifies the aggregated signature AggS to ensure the authenticity of the on-chain data; by halving and extracting the public keys P of multiple nodes, the message push list M of node transactions, and the signature information S, the present invention can directly generate aggregated signature information, thereby improving the verification speed between nodes and increasing the on-chain storage space", but the method for blockchain digital signature transformation in the prior art has the technical problem that it is easy to cause too high temperature during use, resulting in a decrease in the operating efficiency of the device.
