Embodiment Construction

[0038] The information processing flow will be described in detail below in combination with the accompanying drawings.

[0039] (1) AIS message generation and broadcast module, such as figure 1 shown;

[0040] In the implementation process of the present invention, the core part is to finally send the information content to be pushed to the target ship.

[0041] First of all, because the original information content is in Chinese, a Chinese-English conversion process is required to convert the original Chinese information content into English content; secondly, because AIS technology uses 6-bit coded characters, it is necessary to convert the English content from 8-bit The ASCII coded characters are converted into 6-bit coded characters of AIS; again, according to the AIS broadcast mode (point-to-point or broadcast), the 6-bit coded broadcast content is generated according to the message format specified by the AIS technology to generate an AIS broadcast message; finally, th...

Abstract

The invention discloses a VTS information intelligent pushing system based on a ship automatic identification system. The pushing system is composed of an AIS message generating and broadcasting module, a ship sailing plan timed pushing module, a ship sailing plan change pushing module, a sailing security related information pushing module and an intelligent reply information pushing module; when the pushing system is started, the system procedure is to start the threads of the sailing plan timed pushing module, the sailing plan change pushing module, a sailing security related information pushing module and the intelligent reply information pushing module; when the information needing to push is produced, the AIS message generating and broadcasting thread finishes the conversion to the AIS broadcasting message from the original information, and the AIS broadcasting message is sent to an AIS base station, the AIS base station finally sends the message to the target ship through a VHF way. The pushing system disclosed by the invention can guarantee the fast, convenient and accurate confirmation of the ship sailing dynamic information and the sailing security related information between a VTS center and the ship, and the occupancy on a VHF communication channel by this type of information communication is reduced at the same time.

Description

technical field [0001] The present invention relates to the field of AIS and VTS, more specifically, it is a combination of related technologies such as AIS and VTS, and the system intelligently pushes the ship navigation dynamic information and navigation safety related information to the target according to the set rules at regular or irregular times. At the same time, the system can automatically reply relevant information according to the request of the ship. Background technique [0002] The traffic control center has the world's most advanced VTS system, which integrates radar, automatic identification system (AIS) and closed-circuit television system (CCTV) to monitor the traffic of ships 24 hours a day, and monitors the traffic of ships through VHF. Provide high-quality information services, navigation assistance services and traffic organization services. The management and service objects are ships equipped with communication equipment and required by the competen...
