Ship electronic chart data multi-platform shared service device and construction method thereof

Abstract

The invention discloses a ship electronic chart data multi-platform shared service device and a construction method thereof. A server of the device is based on a Linux system and comprises a database for storing an electronic chart, an orthogonal-list-based electronic chart management module, an automatic electronic chart correction module, an information communication module and a data transmission module; and a display and information client is realized on the basis of a Windows system, a Vxworks system and the Linux system, and an electronic chart search module is embedded into the client. The method comprises the following steps of: configuring the server in the Linux system, establishing a display and information client system for different operating systems, inputting the search condition by using the electronic chart search module embedded into the client, searching the chart from the server and downloading to the client. The device is favorable for the centralized and unified management of electronic chart data, and a client system can quickly and accurately download and update the electronic chart data.

Description

technical field [0001] The invention belongs to the field of information technology, in particular to a multi-platform sharing service device for ship electronic chart data and a construction method thereof. Background technique [0002] Electronic charts are authorized by the state and issued according to the specified standards in terms of content, structure and format, and are used by various electronic chart application systems. At present, the development and application of electronic charts and their application systems are hot issues in the field of contemporary navigation. my country's civil ships began to develop and equip electronic chart systems in 1993. Over the years, the focus of research has been on the production and release of electronic nautical charts, the content and effect of nautical chart display, and the impact of electronic nautical charts on ship navigation safety. However, with the increasing application of electronic charts, the following problem...
