Active maritime search and rescue system and search and rescue method thereof

Abstract

The invention discloses an active maritime search and rescue system. The active maritime search and rescue system comprises at least one first search and rescue device, at least one second search and rescue device, a personal device and a base station or ground control center. A first ZigBee application communication module, a positioning module, an AIS module and a first Beidou communication module which are sequentially connected are arranged on the first search and rescue device; a second ZigBee application communication module and a second Beidou communication module which are sequentially connected are arranged on the second search and rescue device; a third ZigBee application communication module is arranged on the personal device; and the base station or ground control center comprises a third Beidou communication module and an electronic sea chart module which are sequentially connected. The invention further discloses an active maritime search and rescue method. A Beidou communication navigation system and a wireless sensing network are integrated, so that precise positioning of a ship in distress, position real-time tracking and precision locating of overboard personnel can be achieved, overboard persons can send self positioning information to salvation equipment by themselves, the search and rescue efficiency is improved, and the search and rescue success rate is improved.

Description

Technical field [0001] The invention relates to the technical field of maritime emergency search and rescue communication, and in particular to an active maritime search and rescue system and a search and rescue method thereof. Background technique [0002] For the current maritime search and rescue, there are still many problems. Ships in distress are mostly sudden accidents. When encountering severe weather and unclear sea conditions, people falling into the water are also affected by factors such as wind and current, and their position cannot be determined. Moreover, the existing marine life-saving equipment has deficiencies, such as: Some life-saving equipment is bulky, heavy, and not easy to carry around, and some cannot tell the search and rescue personnel their exact location, which greatly increases the difficulty of search and rescue. [0003] Among the wireless sensor network technologies, the ZigBee technology that most meets the requirements of low power consumption, l...
