Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle driving data upload to blockchain networks is hindered by unstable communication during vehicle use, leading to delayed data upload and insufficient local storage, and there is a need for flexible node joining or exiting in blockchain networks.
Innovation Solution
A method and device for packing and broadcasting driving data packets at vehicle nodes within predetermined intervals, storing them locally and in nearby nodes, and synchronizing with fixed nodes for timely upload to the blockchain network, allowing flexible node participation and reward allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle data is uploaded through charging pile only during charging, then communication quality is stable, but data upload is delayed and local storage space becomes insufficient
Solution Approach 1:
The patent segments the data upload function across multiple nodes: vehicle nodes perform preliminary packing and local storage, charging pile nodes provide stable upload channels during charging, and roadside nodes enable uploads during vehicle movement. This segmentation allows each node to specialize in specific upload scenarios, resolving the contradiction between stable communication and timely upload.
Solution Approach 2:
Vehicle nodes perform preliminary data packing and local storage before actual upload occurs. This preliminary action ensures data is ready for immediate upload when communication opportunities arise, reducing upload delay while maintaining data integrity and preparing for subsequent synchronized upload to the blockchain network.
2Productivity
If vehicle is in moving state, then vehicle can operate continuously, but communication quality becomes unstable affecting data upload
Solution Approach 1:
The patent introduces road side nodes as intermediaries between moving vehicles and the blockchain network. These fixed nodes act as relay points that receive data from moving vehicles and forward it to the blockchain, enabling continuous vehicle operation while maintaining reliable data upload through the intermediary infrastructure.
Solution Approach 2:
The patent adds a spatial dimension to the data upload architecture by deploying road side nodes along vehicle routes. This transforms the upload problem from a direct vehicle-to-blockchain connection into a multi-point distributed system, allowing vehicles to upload data at any location along their path rather than requiring direct connection to centralized charging piles.
3Adaptability or versatility
If multiple partner nodes and vehicle nodes join blockchain network, then network coverage increases, but node management complexity increases
Solution Approach 1:
The patent segments the blockchain network into distinct node types with specialized functions: vehicle nodes for data generation and preliminary processing, charging pile nodes for stable upload during charging, and road side nodes for mobile upload coverage. This segmentation simplifies management by defining clear roles and responsibilities for each node type while maintaining broad network coverage.
Solution Approach 2:
The patent designs a universal node architecture where different node types (vehicle, charging pile, road side) implement a common interface and protocol for interacting with the blockchain network. This multi-functionality allows diverse nodes to join the network without increasing management complexity, as they all follow the same operational patterns despite different physical characteristics.

AI summary
Methods and devices are provided for uploading driving data to a blockchain network. The method is executed at a vehicle node in the blockchain network and includes: packing driving data of the vehicle node within a predetermined time interval every predetermined time interval to obtain a vehicle data packet of the vehicle, and storing the vehicle data packet locally in the vehicle node; broadcasting the vehicle data packet to other vehicle nodes located nearby and in the blockchain network for the other vehicle nodes to receive and store; receiving and storing other vehicle data packets broadcast by the other vehicle nodes located nearby and in the blockchain network; and when connecting to a fixed node that belongs to the blockchain network, synchronizing the vehicle data packet and the other vehicle data packets as stored to the fixed node, wherein the fixed node participates in the consensus of the blockchain network.
