[3D Barrier Introduction Case Study] Safety Monitoring of Proximity Construction in PA Substructure Works
Construction Field 3D Monitoring System [3D Barrier]
Monitoring of safety zones for adjacent construction work in the lower section of the parking area.
To address the theme of "prevention of contact disasters near general roads" proposed by NEXCO, our company has introduced a 3D barrier and an MR visualization system. These were used for crane operations in an environment where there is a road 200mm ahead, requiring high-precision management measured with a total station. The area around the soundproof wall was designated as a prohibited area, utilizing a system where a patrol light provides warnings based on distance. The MR visualization system was helpful for on-site inspections and for confirming with guiding personnel, thereby enhancing safety measures. In the operator's room, location information can be continuously monitored, and the distance to the prohibited area can be displayed in millimeters, allowing for accurate awareness even during high-altitude work. Additionally, it is equipped with an automatic stop signal output function, which was effective for safety management.

basic information
■Systematizing visual monitoring! Supporting the improvement of on-site safety. Traditionally, monitoring such as crane contact management was done visually, but 3D Barrier systematizes monitoring using crane position information and a unique system, supporting the enhancement of on-site safety. ■Set areas freely to prevent the crane's tip from entering dangerous locations. You can create areas freely using three-dimensional coordinates. Areas can be set in three stages. ■Install an in-vehicle monitor and warning light in the crane operator's room to visualize safety. The current position can be confirmed from the operator's room using the in-vehicle monitor. The warning light operates in conjunction with the set areas, providing alerts in three stages. ■Measurement screen compatible with 3D display. New features to be added in April 2024. The measurement screen and functions have evolved! 【Measurement Screen】 - Switch between 2D/3D display - Import CAD drawings 【New Features Added in April 2024】 - Virtual measurement point addition feature - Screenshot feature - Operation history confirmation feature - Alarm email sending feature
