TECHNICAL FIELD

[0001] The utility model relates to distress search and rescue equipment technical field, concretely is a multimode personal search and rescue position marker. BACKGROUND

[0002] In recent years, with the development of economic society, the fishery, shipping, offshore wind power, ocean survey, offshore engineering and other fields develop rapidly, and people's activities on water are more and more. The working environment on water is bad, and accidents may occur at any time, causing loss of life and property. Therefore, distress alarm devices are often provided for water workers, which can send an alarm and locate the position of the distressed personnel when the personnel are in distress. The existing personal distress alarm products mainly include automatic identification system personnel falling into water position marker (AIS-MOB), Beidou position marker, very high frequency digital selective calling personnel falling into water position marker (VHF DSC-MOB) and the like.

[0003] AIS-MOB can manually or automatically start the alarm after the personnel fall into water, broadcast distress alarm information to the surrounding through AIS data link, and the ships around the AIS shipborne receiver can receive the distress alarm information and implement rescue at the first time.
