Ground Subsidence Detection Device

Device for detecting ground subsidence in facilities using multiple interconnected units

This technology relates to a device for detecting ground subsidence, consisting of a subsidence sensor, a circuit board, a housing, and a cover, which is attached to a facility and connected to other units via cables.

Conventional single-sensor detection systems are prone to false alarms caused by noise or abnormal signals, making it difficult to reliably monitor large areas.

To address this, our technology connects and operates multiple detection units via cables, eliminating mutual sensor errors to provide precise and highly reliable ground subsidence detection.

* This invention is the result of the project 'Real-time Railway Rail Safety Monitoring Using 3-Axis Displacement Sensors,' supported by the Ministry of SMEs and Startups.

Key Features:

• Ground subsidence sensor for sensing facility-related information and a circuit board housing it
• Housing attached and fixed to the facility, including a fastening groove that surrounds the circuit board and engages with a fastening member
• Cover that prevents the fastening member from detaching and encloses the cable structure electrically connected to the circuit board
• Multiple ground subsidence detection units electrically connected to each other via the cable structure to detect subsidence
