IoT Sensors Installed on 79 Facilities Including Old Bridges, Underpasses, and Retaining Walls for 24-Hour Safety Monitoring

# Sensors are installed on the pillars of the pedestrian overpass at Central City in Banpo-dong, Seocho-gu. The sensors continuously detect vibration, tilt, and crack conditions every 10 minutes and notify the district office staff in real time.

When the vibration and tilt applied to the overpass exceed the threshold, an alarm sounds on the district office staff's computer and a text message is sent to their mobile phone.

The Seocho-gu office staff immediately checks the safety management system screen to identify which part of the pedestrian overpass has the issue.

Seocho-gu, Seoul (Mayor Jeon Seong-su) announced that starting this month, it will introduce a digital-based facility safety management system for 79 aging facilities in the area, including the Central City pedestrian overpass in Banpo-dong, Nue Bridge in Seocho-dong, and Aqua Art overpass.

This system uses digital twin technology and Internet of Things (IoT) sensors to monitor vibration, tilt, and crack information of the facilities in real time, 24 hours a day.

In particular, the district applies digital twin technology to three facilities where visual safety inspections are difficult: the Nue Bridge overpass in Seocho-dong, the Central City pedestrian overpass, and the Aqua Art overpass.

This is the first case among local governments nationwide to combine digital twin technology with a safety management system. It implements a 3D model similar to the actual structure, allowing for zooming, rotating, and multi-angle inspection of the condition. It enables quick and accurate safety inspections through pre-checking structural cracks, vibrations, and tilts based on measured data.

Additionally, the district installs measurement sensors on parts of aging facilities such as pillars and trusses (beam structures) where pressure or cracks are likely to occur. If vibrations or cracks exceeding the threshold are continuously detected by the sensors, the situation is automatically communicated via text messages to the safety general manager and facility managers. This allows the district to conduct scientific risk analysis and prediction, enabling prompt response when necessary.

This project was selected as the top candidate after Seocho-gu participated in the 2022 Ministry of the Interior and Safety’s “Digital-Based Safety Management System for Aging and Risk Facilities” competition, receiving high evaluations for its digital twin technology integration plan and proactive project promotion.

Jeon Seong-su, Mayor of Seocho-gu, said, “Operating a digital-based safety management system will enhance the accuracy of facility safety management and greatly contribute to the safety of residents.” He added, “We will continue to actively utilize digital technology to create a safer Seocho-gu.”
