A Safety Warning Algorithm Based on Axis Aligned Bounding Box Method to Prevent Onsite Accidents of Mobile...

Area of Science:

• Construction Safety Engineering
• Geotechnical Engineering
• Robotics and Automation

Background:

• Dynamic construction sites present continuous risks of accidents involving mobile machinery, such as overturning or collapsing into hazardous areas like foundation pits or soft soil.
• Current safety management techniques lack practical solutions for real-time monitoring and prevention of machinery entering dangerous zones.
• Human monitoring is insufficient due to the constantly changing site environment and the impossibility of continuous surveillance.

Purpose of the Study:

• To develop a practical safety warning algorithm to prevent mobile construction machinery from entering hazardous areas.
• To reduce onsite accidents, including machinery overturning and collapsing.
• To enhance safety management techniques for mobile construction machinery.

Main Methods:

• Utilizing wireless sensor devices to collect real-time location data of mobile construction machinery.
• Developing a safety warning algorithm based on onsite safety management regulations.
• Proposing a modified axis-aligned bounding box method tailored to machinery movement patterns.

Main Results:

• The developed algorithm effectively detects risks and provides timely warnings when machinery approaches hazardous zones.
• A real-case simulation validated the algorithm's efficacy in a warning zone scenario.
• The integrated system of location sensing and the modified bounding box method proved successful in timely risk detection.

Conclusions:

• The proposed algorithm offers a practical solution for real-time safety monitoring of mobile construction machinery.
• Implementation of this system can significantly reduce onsite overturning and collapsing accidents.
• This technology enhances daily onsite safety management by preventing machinery from entering risk areas.
