At present, the management of the crew on many ships is still achieved through manual operations, without a complete information management system; on the other hand, the cabin is generally a steel plate structure, and it is difficult to locate the crew on the ship without changing the existing hull structure very big. Especially after a dangerous situation occurs, there may be a large number of wounded in a short period of time. At this time, the wounded rescue work will encounter greater difficulties: first, the dangerous situation is unpredictable, when, where, and who is injured or falls into the water. The severity of the injury needs to be identified in time; second, the internal structure of the hull is complex, the location of the wounded is difficult to obtain, and timely search and rescue is difficult.

In recent years, positioning and vital sign monitoring have become research hotspots, but most of them focus on the fields of elderly care and mine worker safety. There are few studies on personnel positioning and vital sign monitoring in ship cabins. The shielding of wireless propagation signals by the steel structure of the ship's cabin has a lot to do with it. In order to improve the ability and level of wartime rescue, from 1996 to 2003, the US Navy funded Georgia Tech University to conduct research similar to smart clothing, called the Georgia Tech wearable motherboard (GTWM). The research has gone through three generations of products, which can monitor human body temperature, heartbeat and respiration. In addition, the "U.S. Navy 2015 Military Science and Technology Strategy (2015 Naval S&T Strategy)" also emphasized the importance of wireless vital sign monitoring, requiring that "this kind of equipment tied to the arms or thighs of sailors and navy can immediately Capture their vital signs and other information, and transmit it to the monitoring system of the emergency center in time to guide the rescue." In my country, the research on positioning and vital signs monitoring in the ship cabin started relatively late, and it has only been reported in the literature in recent years. For example, Qi Liang, Sha Kun, etc. conducted research on the positioning system of the wounded and sick at sea, and initially designed a positioning scheme for shipboard individual soldiers and those who fell into the water. In addition, Han Zhihai, Ni Jian and others conceived of the monitoring system for the life status of individual soldiers at sea and the rapid collection and processing device for vital sign information of the wounded and sick at sea.
