Vital sign monitoring system for diver in underwater operation

Abstract

The invention discloses a vital sign monitoring system for a diver in underwater operation. The system comprises a vital sign signal detection and sending unit, a vital sign signal receiving unit and a computer, wherein the vital sign signal detection and sending unit is composed of a signal detection and amplifying unit, an analogue / digital conversion circuit, a first microprocessor, a storage circuit, a wireless sensing circuit and a sensor; the vital sign signal receiving unit is composed of a wireless receiving circuit, a second microprocessor and a communication interface circuit; the wireless receiving circuit is connected with the wireless sending circuit through a wireless link; and the sensor comprises an electrocardio detection electrode which is composed of conductive fabric. The sensor is arranged on the diver body and transfers a signal to the wireless receiving circuit in a short-range diving bell through the wireless sending circuit; and the signal is transferred to thecomputer on the water surface through the communication interface circuit and the cable so that various physical signs of the diver in underwater operation can be monitored in real time; and moreover, wire long-range transmission is adopted between the diving bell and the computer on the water surface, and thus the signal is stable and reliable.

Description

Technical field: [0001] The invention relates to the field of physics, in particular to measurement technology, in particular to a vital sign monitoring system for divers working underwater. Background technique: [0002] As the development and utilization of marine resources continue to increase, offshore construction and salvage are increasingly frequent, and there are more and more opportunities for underwater operations. In the process of diving operations, the longer the time and the greater the diving depth, the greater the impact on divers. the greater the potential threat. Diving operations can cause CO in the diver's body 2 Retention increases the concentration of hydrogen ions in the cerebrospinal fluid, affects the metabolism of brain cells, reduces the excitability of brain cells, and inhibits cortical activity; 2 increase, the subcortical layer is inhibited, the central nervous system is in a state of anesthesia, and the consequences are disastrous. In the pr...
