Ship positioning communication method and navigation terminal used for ship

Abstract

The invention discloses a ship positioning communication method. The method includes the following steps: selecting one positioning device with high signal intensity to position a ship according to the signal intensity of positioning devices, the positioning devices including a BeiDou positioning device and a GPS positioning device; storing ship position data obtained by the positioning device in a storage medium; and on the basis of signal intensity of communication devices, selecting one communication device with high signal intensity to send the ship position data to a shore, the communication devices including a GPRS communication device and an Iridium communication device. Through the above technical scheme, ship position information is known in real time, real-time communication is realized, and ship supervision during an emergency and after the emergency is tightened.

Description

technical field [0001] The invention belongs to the field of ship real-time monitoring methods, in particular to a ship positioning communication method. In addition, the present invention also relates to a marine navigation terminal. Background technique [0002] The 21st century is the era of sea power. There are more and more ships such as transport ships, fishing ships, and fishing boats on the ocean. Ship navigation is becoming more and more difficult, and there are more and more ship accidents, and these accidents are often not. traceability. More often than not, fishing in the oceans and seas often involves cross-border fishing, or other countries' illegal high seas law enforcement, which leads to tensions in international relations. The occurrence of these frictions is still not traceable, and there is no conclusive evidence, leading to intensified conflicts. [0003] Therefore, the current real-time monitoring of ship navigation is weak and has no traceability, wh...

Problems solved by technology

[0002] The 21st century is the era of sea power. There are more and more ships on the ocean, such as transport ships, fishing boats, and sea fishing boats. The difficulty of navigation is also increasing, and there are more and more ship accidents. Traceability

What's more, the current ocean fishing and high sea fishing often lead to cross-border fishing, or other countries' illegal law enforcement on the high seas, which leads to tension in international relations. These frictions are still not traceable, and there is no conclusive evidence, leading to intensified conflicts.
