Construction Machine Model Reproduction Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need in the field of construction machine operations to analyze and compare the movements of different construction machines, particularly to identify differences in their operations, especially when one machine fails or operates abnormally, without the need for a dedicated camera on site.
Innovation Solution
A reproduction apparatus that acquires log information from construction machines, applies angle information to a construction machine model to reproduce operations, and synchronizes the reproduction based on first and second log information to ascertain movement differences between machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If log information is acquired and reproduction is performed without synchronization, then individual machine operations can be reproduced, but movement differences between machines cannot be ascertained
Solution Approach 1:
The patent creates virtual copies (reproduction models) of construction machines based on log information from multiple machines. By synchronizing these virtual models in time, the system can compare and detect movement differences between machines without requiring physical measurement devices on each machine, thus improving measurement precision while avoiding additional hardware complexity
Solution Approach 2:
The patent introduces a synchronization unit as an intermediary component that aligns the reproduction timing of multiple construction machines. This mediator synchronizes the virtual models based on time information from log data, enabling accurate movement difference detection without direct interaction between the actual machines, thereby resolving the contradiction between measurement accuracy and system complexity
2Loss of information
If detailed movement analysis is performed without synchronization, then operational data can be recorded, but comparative analysis between machines is impossible
Solution Approach 1:
The patent performs preliminary synchronization of reproduction models before conducting movement difference analysis. By pre-aligning the virtual models in time based on log information, the system preserves all movement comparison information without needing to process and synchronize data during the analysis phase, thus preventing information loss while minimizing time loss through upfront preparation
