BIM-Guided Crane Control for Precise Load Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for controlling construction machines like cranes using Building Information Models (BIM) are limited in efficiency and safety, and face real-time challenges due to data transmission speed and bandwidth issues, particularly in time-sensitive tasks such as sway control.
Innovation Solution
A construction machine control device connected to a construction site control computer that accesses a BIM, enabling data exchange and semi-automated or fully automated operation through modules like data exchange, component localization, detection, stroke control, lift control, and travel control, using sensors and communication systems like RFID, RuBee, and wearable technology for precise movement and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time data exchange between construction machine control device and BIM model is implemented, then control precision and safety are improved, but data transmission speed and bandwidth become limiting factors
Solution Approach 1:
The system pre-loads and caches BIM model data and construction site information into local memory before real-time control operations begin. This preliminary data preparation ensures that when real-time control decisions are needed, the data is already available locally, eliminating transmission delays and bandwidth constraints while maintaining high control precision.
2Productivity
If fully automated control operations are implemented, then productivity is improved, but system complexity increases
Solution Approach 1:
The construction machine control device automatically retrieves data from the BIM model, processes construction information, and executes control decisions without requiring constant human intervention. The system serves itself by autonomously making real-time control decisions based on cached data and sensor feedback, thereby improving productivity while the modular architecture manages complexity through standardized interfaces.
3Reliability
If comprehensive BIM data integration is implemented, then collision detection and safety monitoring are improved, but data processing time increases
Solution Approach 1:
The system extracts and caches only the specific BIM data elements relevant to real-time control decisions, such as component locations, installation sequences, and collision zones, rather than processing the entire BIM model. This selective data extraction maintains comprehensive safety monitoring while significantly reducing data processing time by focusing only on critical information needed for immediate control actions.
