Problems solved by technology

However, there are performance bottlenecks in the current single-chain blockchain, and high redundancy brings huge storage overhead, which has great limitations in application scenarios. In power grid scenarios that need to process massive amounts of data, the power consumption data collected It is not feasible to chain to a single blockchain system

Embodiment Construction

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the layered multi-chain based IoT terminal data processing method and system proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation methods described here are only used to explain the present invention, and are not intended to limit the present invention.

[0029] The inventors found in the research of power grid data management methods that most of the existing power grid data management methods use a centralized system with centralized storage and calculation, which has the problems of single point of failure and data security protection. When faced with massive data processing, centralized systems are also Bring system performance and scalability issues. Some solutions propose to improve the centralized system to provide edge computing services at ...

Abstract

The invention provides an Internet of Things terminal data processing method based on layered multi-chains, which comprises the following steps: constructing a multi-layer block chain network by using a plurality of block chain sub-chains, dividing Internet of Things terminals into a plurality of groups, and allocating one sub-chain to each group of terminals; dividing the current-layer sub-chains into multiple groups, and allocating an upper-layer sub-chain to each group of current-layer sub-chains; and uploading terminal data acquired by the terminal to the sub-chains of the group, performing consensus verification on the terminal data by the sub-chains, integrating the verified terminal data, and continuously uploading the integrated data to the upper sub-chains of the group until the integrated data of the terminal data is integrated on the uppermost sub-chains. The invention further provides an Internet of Things terminal data processing system based on the layered multi-chains.

Description

technical field [0001] The invention relates to the technical fields of block chain and Internet of Things, and in particular to a data processing method and system of an Internet of Things terminal. Background technique [0002] Part of the current power grid power data management system in operation still needs to rely on manual data collection, and then recruit it into a local centralized system divided by administrative regions. In this process, there are problems such as unreliable data sources caused by staff mistakes and other reasons, and it is impossible to track the user's power consumption in real time, which is inefficient. In response to this situation, the academic community has proposed the concept of "smart grid" in recent years, hoping that the power data management system will realize the automatic real-time collection of electricity data from source terminal equipment such as "smart meters" and send it to the cloud. The cloud is a centralized system for ce...
