Portable positioning device for maritime distress person

Abstract

The invention discloses a portable positioning device for a maritime distress person. In a working state, a photoelectric sensor emits light to be converged on the skin of a person in distress, afterthe light of the specific wave band light is absorbed by the blood, a photosensitive receiver collects reflected light signals after absorption and converts the light signals into electric signals; awater pressure sensor is used for detecting water pressure information, and triggering an alarm signal and outputting the alarm signal when the water pressure sensor detects that the water pressure isgreater than a set threshold; a Beidou satellite positioning module is used for carrying out geo-location on the person in distress; a master control module integrates and then transmits current location information, physiological state information, and vessel identity information of the person in distress to a communication unit, and the communication unit is in data communication with a shore-based command center; and when the water pressure sensor transmits an early warning signal to the master control module, the master control module controls a radar transponder to be in a receiving state so that the radar transponder can wait for receiving a search signal sent by a search and rescue radar on a rescue boat or a rescue aircraft.

Description

technical field [0001] The invention relates to the field of maritime distress rescue, in particular to a portable positioning device for persons in distress at sea. Background technique [0002] Rescue plan: "Golden 72 hours" is the golden rescue time after geological disasters. During this time period, the survival rate of victims is high. The sea environment is complex, and the golden time of sea rescue is a relative concept, which means that the survival rate of people in distress during this time period is high. After a shipwreck, people in distress may have different injuries, and the golden rescue time is different for different injuries, such as fractures, gallstones and other injuries. If they are not life-threatening, the golden rescue time is 6 hours, but bleeding, coma, etc. For injuries, the golden rescue time is 3 hours. Therefore, it is very important to grasp the physiological status information of people in distress at sea. If people at sea can transmit t...

AI Technical Summary

Problems solved by technology

The current rescue system for people in distress at sea is mainly to install alarm devices on the ship’s base. When they are in distress, they cannot locate all the people in distress, they cannot grasp the physiological status information of the people in distress, and they cannot reasonably allocate rescue resources according to the different injuries of the people in distress. Missing the golden rescue time, resulting in an irreparable cost of life
