At present, the management of many ships to crews is realized by a manual operation mode, and no perfect information management system exists; on the other hand, the cabin is generally of a steel plate structure, and the positioning difficulty of ship personnel is high under the condition that the existing ship body structure is not changed. Particularly after a dangerous situation, a large number of wounded persons may occur in a short time, and the wounded persons will encounter great difficulties in rescue work: one dangerous situation is difficult to predict, when, where, who is injured or falls into water is unknown, and the wounded condition of the wounded person is light and urgent and needs to be identified in time; the internal structure of the two ship bodies is complex, the position of a wounded person is not easy to obtain, and the wounded person is difficult to spread in time for searching and rescuing.
In recent years, positioning and vital sign monitoring become research hotspots, but most focus on the fields of aged nursing, mine worker safety and the like, and the research of positioning personnel in a ship cabin and monitoring vital signs is less, so that the positioning and vital sign monitoring method has great relation with the situation that the land demand is greater than the water demand, the ship cabin steel structure shields wireless transmission signals and the like. To improve the ability and level of rescue during war, a similar smart garment study was conducted from the university of the united states navy sponsored arbor and sub-regulator in 1996-2003, called arbor and sub-regulator wearable motherboard (the Georgia Tech wearable motherboard, GTWM). The study is carried out by 3 generations of products, and the monitoring of the body temperature, the heartbeat and the respiration of the human body can be realized. In addition, the importance of wireless vital sign monitoring is emphasized in the U.S. naval 2015 military science and technology policy (2015Naval S&T Strategy), which requires that such devices tied to the arms or thighs of the soldier and naval can immediately capture information such as their vital signs at the time of their injury, and transmit the information to the emergency center monitoring system in time, leading the rescue. The research of positioning in the cabin of the ship and monitoring vital signs in China is started later, and only in recent years is literature reported. Research on the positioning system of the marine sick and wounded is carried out, such as the positioning system is bright, sha and the like, and the positioning scheme of the carrier-borne individual soldier and the person falling into water is preliminarily designed. In addition, han Zhihai, ni Jian and the like contemplate a maritime individual life state monitoring system and a maritime sick and wounded vital sign information rapid acquisition and processing device.
However, the convenience and effectiveness of the positioning and management systems currently used for ships have yet to be improved.
