SYSTEM AND METHOD OF MONITORING FOR PREVENTING COLLISION OF CRANES USING GNSS

摘要

PURPOSE: A crane conflict prevention monitoring system and method are provided to automatically control the movement of a crane for preventing the conflict between cranes by notifying a conflict risk to a operator and a central management part. CONSTITUTION: A crane conflict prevention monitoring system comprises a central management part(100), a jib crane(10), a GNSS(Global Navigation Satellite System) receiver, and PC terminals(50,150). The GNSS receiver is installed in a central axis and a boom of the jib crane and receives GNSS location information. The GNSS receiver transmits the GNSS location information to the central management part. The PC terminal is included in cranes and operates a conflict prevention program and comprises a monitor for conflict prevention. The central management part transmits GNSS location correction data to the GNSS receiver of the cranes. The PC terminal receives location information from the GNSS receiver of the cranes and indicates a current location of entire cranes operating in workplace in real time. The PC terminal operates the conflict prevention program when a mutual conflict risk is generated.
