Problems solved by technology

[0003] The current problem is that the information cannot be shared because the water monitoring information system and the VTS system are independent of each other.
However, when people use electronic maps, the tracking objects displayed on the map are usually represented by the same symbols (such as cars, ships), and the rich natural attributes such as types, colors, sizes, and directions inherent in graphic symbols are not fully utilized. And give these attributes different meanings to simplify people's visual perception and identification process of things, and there are no corresponding graphic identification standards and norms.

Embodiment 1

[0080] Embodiment 1 Nautical chart information display and query

[0081] Provide electronic chart display in Dalian sea area, realize basic functions such as map zoom-in, zoom-out, roaming, geographic location display, etc., and also realize advanced applications such as point, line, surface labeling, distance and area calculation, eagle eye, map printing, etc. Features. Provide map query and conditional query to obtain any chart information, navigation information, and object information. Map query can query any object information within the corresponding map range by clicking, drawing frame selection, circle selection or polygon selection; conditional query can perform fuzzy query and positioning through keywords. The query results are displayed or printed out in graphs and tables.

[0082] The main functions are introduced below.

[0083] 1.1 Display the full chart

[0084] After clicking the button to display the full image, the electronic chart...

Embodiment 2

[0101] Embodiment 2 Ship dynamic information display query

[0102] On the basis of the above-mentioned electronic chart application platform, by receiving ship dynamic data (VTS and water monitoring system) in real time, it can visually display and query ship dynamic information, and can visually display the real-time position and location of all ships in port on the electronic chart. Click on the ship logo to get its general attributes, anchoring status, entry and exit plan and other dynamic information.

[0103] General information of the ship: ship name, call sign, tonnage, nationality, ship type, etc.

[0104] Ship dynamic information: ship position, course, speed, departure port, destination port, entry and exit plan, etc.

[0105] 2.1 Fuzzy query of ship dynamics

[0106] By selecting Chinese and English ship names, call signs, and ship types, and entering keywords, you can perform fuzzy queries on the current ships in the port.

[0107] 2.2 Circular...

Embodiment 3

[0111] Embodiment 3 Berth and anchor position dynamic information display query

[0112] It can visually display the real-time position of all berths and anchorages and the berthing distribution of ships in them on the electronic chart. Click on the berths and anchorages to obtain their general properties, berthing status, berthing plan and other dynamic information of each berth and anchorage . And it can locate the distribution of ships, berths and anchorages that meet the conditions through keyword fuzzy query.

[0113] 3.1 point query berth

[0114] Select the point in the map query to query the berth, and click the berth of the wharf on the map with the left mouse button, and information such as the berth of the wharf and whether the berthing ship is legal will appear.

Abstract

A symbol identification system of vessel state on electronic sea chart is featured as setting server in network to connect with water surface monitoring data server and VTS system data server for obtaining vessel entering and leaving prereport and approval information in real time and for obtaining vessel entering and leaving plan as well as anchorage and berthage data; centralizing obtained data to set up databank; applying browser / server structure to integrate with geographical information system to realize visible display and inquiry of vessel state space data of vessel entering and leaving anchorage, berthage, etc on electronic sea chart by each terminal in network.

Description

technical field [0001] The invention belongs to the technical field of computer intelligence. Background technique [0002] The ship management system is an information system used by the maritime department to manage ships, including ship registration management systems, security inspection systems, visa and inspection systems, and ship dynamic systems. The software system of the water monitoring information system covers the entire Liaoning Maritime Safety Administration and has an independent server and database. Dalian VTS system is the traffic control business management system, which is an information system for traffic management of ships entering and leaving Dalian port area. The VTS system of Dalian Port is self-contained, with independent hardware equipment system and management mode, and its information system has a dedicated server and database. The data of the VTS system mainly includes data such as ship arrival plan, ship berth, anchor position, etc. [0003...
