Crew maritime intra-cabin positioning, vital sign monitoring and searching-rescuing method

The invention discloses a crew maritime intra-cabin positioning, vital sign monitoring and searching-rescuing method based on a crew maritime intra-cabin positioning, vital sign monitoring and searching-rescuing system. The system comprises a command center server, an electronic fence transmitter, a crew vital sign real-time monitor, a crew real-time positioner, a shipboard personnel positioning processor and an overboard personnel positioner. According to the method, the vital sign real-time monitor for a single crew member, the shipboard and overboard personnel real-time positioners as well as wounded personnel vital sign and positioning data transmission are researched on the basis of such modern information technologies as AIS (automatic identification system), UWB (ultra-wide band), compass navigation positioning and the like, so that the automation of maritime wounded personnel vital sign monitoring, the electronization of information storage, the networking of information transmission and the visualization wounded personnel rescuing are achieved.
