hello. LOBSE Co., Ltd. measures the wear of railway wheels and rails through non-contact laser sensing in the field of disaster safety and provides solutions to prevent railway vehicle derailments through various maintenance measurement systems. As the first product, we introduce a rail profile wear measurement device with a non-contact laser displacement sensor. It is a portable, mobile-based rail profile wear measurement device that has secured high-precision wear measurement and real-time visualization analysis technology on the rail surface in a certain section. High precision and high added value. We propose a rail replacement cycle through history management by reducing inspection costs and securing stability through local production of rail profile wear. The rail profile wear measurement equipment “Railops” is portable and can be easily mounted on the bottom of the rail. Simple operation and quick installation are possible through miniaturization and wireless design. Through belt-driven step motor control, the displacement sensor moves left and right with precision and scans over the rail cross-section. The data measured by controlling the operation of the displacement sensor is collected and analyzed by the MCU control module and firmware. Transferred to tablet software Afterwards, when you tap Scan on the main dashboard, the displacement sensor mounted on the rail starts rolling and scans the cross section of the rail profile. Afterwards, the rail profile wear information is visualized on the wear graph. When you press Save, the data is saved and the next rail profile is measured through reset. It is used for saved data reports, and also implements an active maintenance system by notifying rail profile replacement cycles through storage and backup on the institutional server. The rail profile wear measurement device using the non-contact laser sensor of ROBS Co., Ltd. has secured reliability through technology transfer from the Korea Railroad Research Institute, and based on this technology, we will take responsibility for a safe future for railroads by preventing railroad derailments.
