The invention discloses a VTS (vessel traffic service) system based on RPR (resilient packet ring) technology. The VTS system comprises a radar, a closed-circuit television monitoring system, a VHF (very high frequency) communication station, an automatic vessel identification system base station, a radio direction finder, a sonar, a processing computer, a display control computer and a server. The radar, the closed-circuit television monitoring system, the VHF communication station, the automatic vessel identification system base station, the radio direction finder, the sonar, the processing computer, the display control computer and the server are connected to the VTS system through RPR nodes, so that the VTS system is integrated with IP intelligence, Ethernet economy, and high bandwidth efficiency and reliability of an optical fiber ring network.
