Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] figure 1 It is a schematic diagram of the architecture of the AIS base station virtual navigation mark broadcast monitoring system of the present invention.

[0022] See figure 1 , the present invention proposes a method for monitoring the integrity of AIS base station virtual aids to navigation, which is composed of hardware and software. The receiving station monitors the beacon signal and sends the monitoring information back to the monitoring center; the software part includes: AIS base station management, virtual navigation mark management, reference receiving station management, alarm policy setting, automatic alarm, map monitoring platform, system management, etc., monitoring After the central integrity monitoring software receives the returned data, it analyzes and judges whether the broadcast of the navigation mark is normal according ...

Abstract

The invention discloses an AIS base station virtual navigation mark broadcast monitoring system and an AIS base station virtual navigation mark broadcast monitoring method. The AIS base station virtual navigation mark broadcast monitoring method comprises the steps of: setting AIS base stations to broadcast virtual navigation mark signals, wherein each AIS base station adopts a plurality of transmitters as standby redundancy; setting a reference receiving end to monitor the virtual navigation mark signals from the AIS base stations, and transmitting monitoring information back to a monitoring center; and calculating reception quality of the reference receiving end and transmission quality of the AIS base stations at the monitoring center so as to obtain integrity evaluation data of the transmitters, and alarming and switching the primary and standby transmitters according to the integrity evaluation data. Through the arrangement of the reference receiving end, the virtual navigation mark signals from the AIS base stations are monitored, and the integrity evaluation data of the transmitters are obtained through calculation to carry out alarming and switching on the primary and standby transmitters, thereby ensuring the continuity and integrity of AIS base station virtual navigation mark broadcast, and greatly improving safety and reliability of navigation by means of the virtual navigation mark.

Description

technical field [0001] The invention relates to a navigation mark monitoring system and method, in particular to a monitoring system and method for AIS base station virtual navigation mark broadcasting. Background technique [0002] A virtual navigation mark refers to a digital information object that does not exist physically and can be displayed in the navigation system issued by the authorized navigation service provider (IALA definition). It is recognized by the International Society of Aids to Navigation following the visual aids to aids, audio aids to aids, and radio aids to aids. [0003] Domestically, AIS virtual aids to navigation have been widely used in the coastal waters of Dalian, Tianjin, Qingdao and the Yangtze River estuary. The number of virtual AIS aids to navigation in the East China Sea has reached more than 80, and it has also been piloted in the inland waterways of the lower reaches of the Yangtze River. The extension section of the Yangtze River Estua...
