Ocean environment-based armpit vital sign transmission positioning search and rescue system

Abstract

The invention discloses an underarm vital sign transmission positioning search and rescue system based on a marine environment. The underarm vital sign transmission positioning search and rescue system comprises an underarm vital sign collection and positioning transmitting module, a receiving and forwarding module and a position display and search and rescue module. A vital sign collecting unit, a positioning unit and a wireless hidden transmitting unit are arranged in the armpit type vital sign collecting and positioning transmitting module. The receiving and forwarding module comprises a radio receiving unit and a signal forwarding unit. And the position display and search and rescue module comprises a drowning person position identification, determination and display unit. Through the matching of the three modules, the position of a drowning person is quickly and automatically positioned and tracked, and meanwhile, the position information and vital sign information of the drowning person are sent, so that search and rescue personnel can conveniently go to rescue, and a means is provided for timely finding the drowning person and effectively rescuing. The system has the advantages of being high in efficiency, fast in response, accurate in position report, not prone to being found by non-partners, capable of reporting human body vital sign parameters in time and the like.

Description

technical field [0001] The invention relates to an underarm vital sign transmission positioning search and rescue system based on the marine environment, belonging to the field of safety and lifesaving, through the underarm vital sign collection and positioning emission module, receiving and forwarding module, position display and search and rescue module, in the entire search and rescue system During the process, changes in the vital signs of patients can be detected, and at the same time cooperate with lifeboats, helicopters and base stations to quickly locate and effectively rescue victims. Background technique [0002] At present, the life-saving and rescue systems equipped on ships are not perfect. When the offshore workers fall into the water, the life-saving methods commonly used at present cannot be accurately located. The essence of satellite positioning is radio positioning. Only by receiving radio signals can the user's position be obtained. Water is also one of ...

AI Technical Summary

Problems solved by technology

However, the attenuation of radio signals under water is severe, and the degree of attenuation is related to the frequency of the signal

The satellite signal itself is a high-frequency signal, and it is difficult to meet the positioning needs of underwater users simply through satellite navigation.

Therefore, once a person falls into the water, it is difficult to locate the GPS positioning device in time due to the immersion in seawater. big difficulty
