VTS (vessel traffic service) system based on RPR (resilient packet ring) technology

Abstract

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.

Description

technical field [0001] The invention relates to a ship traffic service system. Background technique [0002] VTS (Vessel Traffic Service) system is a set of ship traffic built by integrating electronic equipment systems and supporting auxiliary systems to protect water infrastructure (such as bridges, oil platforms, etc.), improve water navigation efficiency, ensure navigation safety and protect the water environment. Management system, its main integrated electronic equipment mainly includes radar, closed-circuit television monitoring system (CCTV), RDF, sonar, weather sensor, VHF communication station, ship automatic identification system (AIS) and control Stands (computers, monitors, controls, servers), etc. [0003] Existing VTS systems usually use the tree structure of ordinary IP LANs to send, transmit, and receive information. The information interacted in the system includes: radar video, radar plotting video (track, point track data), equipment failure / status infor...

AI Technical Summary

Problems solved by technology

[0005] In order to ensure real-time requirements, high-bandwidth or dedicated lines are used, which brings about a large demand for optical cables or cable resources and excessive construction costs;

[0006] It cannot completely meet the needs of different network supports for different services (video, image, voice, data, etc.). When there are few targets in the water area of ​​the jurisdiction and the radar detection clutter is less, it can meet the basic duty requirements. When there are too many waves, the quality of various information cannot be satisfied, including the uncontrollable end-to-end delay (belonging to the best-effort transmission system);

[0007] Business expansion is difficult, and the cost is high; when the existing VTS system needs to add several nodes, and the estimated transmission capacity exceeds the existing bandwidth limit, the communication network needs to be rebuilt, and the cost is high;

[0008] The network security is low. When the central node fails, the entire network may be paralyzed, and information transmission protection cannot be performed, and there is no redundant backup
