LG Uplus will build an AI safety control system based on real-time kinematic (RTK) high-precision positioning to strengthen safety for port workers at Busan New Port's Terminal 5.
LG Uplus said on the 22nd that it will establish a system with BNCT, the operator of Busan New Port's Terminal 5, and CyberLogitec, a shipping and port IT specialist, to track the real-time locations of mobile equipment and workers and warn in advance of hazardous situations.
The core of the system is to precisely calculate the locations of mobile equipment such as container handling vehicles with RTK and to prevent accidents by sending immediate alerts to workers, equipment, and the control center when risk signs are detected through AI-based CCTV analysis. The existing global navigation satellite system (GNSS) has errors of up to about 15 meters, limiting precise control in environments like ports where large equipment moves frequently and lines of sight are restricted.
LG Uplus applied an RTK method that incorporates correction data by linking ground reference stations with dedicated terminals. In a proof-of-concept last year, it tracked the positions of straddle carriers in the port to within 1–2 centimeters and implemented automatic alarms based on distance thresholds between workers and equipment. The company said it proved the reliability and stability of its location information by establishing a system that transmits correction data generated from 200 ground reference stations nationwide without interruption 365 days a year over its own communications infrastructure.
The three companies signed a construction agreement in Dec. last year and plan to fully deploy the system by applying RTK to about 70 mobile units operating at Terminal 5 by the second half of this year. They will also push to expand the application to other terminals within Busan New Port.
