Search and rescue terminal equipment based on Beidou, AIS and underwater acoustic technology

Abstract

The invention relates to a search-and-rescue device based on Beidou, an AIS and an underwater acoustic technology. The device comprises a satellite positioning communication module based on a Beidou satellite positioning system, an AIS (shipbore automatic identification system) module, an underwater sound transduction module, a pressure sensor, a microprocessor, and a power module. The microprocessor is used to form help-seeking messages according to satellite positioning signals, and emit the messages through the satellite positioning communication module or the AIS module. The microprocessor is also used to control the satellite positioning communication module and the AIS module to be in non-operating states when current water depth of a search-and-rescue terminal device is determined to reach preset water depth according to pressure acquisition signals, and controls the underwater sound transduction module to generate acoustic signals, if not, the underwater sound transduction module is controlled to be in a non-operating state, and the satellite positioning communication module or the AIS module is controlled to be in an operating state. The device can make rescue personnel obtain specific positions of search-and-rescue terminal devices in time through a plurality of methods, and the search-and-rescue terminal devices is further improved, so as to improve rescue efficiency and rescue success rate.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a search and rescue terminal equipment based on Beidou, AIS and underwater acoustic technology. Background technique [0002] After the occurrence of disasters such as air crashes, marine accidents, and tourism accidents, it is very important for rescue work to quickly find the victims and people in distress, and provide emergency assistance to the surviving victims and people in distress. [0003] During the rescue process, the victims are usually found with the help of instruments and equipment; if the victims or ships and other items are equipped with search and rescue terminal equipment, it is very beneficial to the rescue work. [0004] In the process of realizing the present invention, the inventor found that after the disaster, the conditions on the scene were often complicated due to factors such as the weather, the environment, and the limitation of rescue e...
