Novel intelligent clothes with warning function

Abstract

The invention discloses novel intelligent clothes with a warning function. A physiological characteristic monitoring system comprises a monitoring system front end and a monitoring system back end, wherein the monitoring system back end comprises an illuminant and demodulation module (3) and a warning system (13); a spacesuit underwear (1) as the monitoring system front end comprises a first fiber grating (6), a second fiber grating (7), a third fiber grating (8), a fourth fiber grating (9), a fifth fiber grating (10), and curved optical fiber (12); one end of the curved optical fiber (12) is connected with any fiber grating in series, and the other end of the curved optical fiber (12) is connected with the illuminant and demodulation module (3) through optical fiber (2); the five fiber gratings (6)-(10) pass through a coupler (5) to be connected with the illuminant and demodulation module (3) through optical fiber (4). The novel intelligent clothes provided by the invention are simple in structure, high in detection precision, good in reliability, diversified in functions, lower in manufacturing cost and comfortable to wear. The intelligent clothes can be used in the field of spaceflight and aviation, and can be used for detecting the body temperature and the respiratory rate of an astronaut at the same time, so as to monitor the two physiological characteristics of the astronaut in a real-time manner.

Description

technical field [0001] The present invention relates to a smart clothing in the field of aerospace, in particular to a technology capable of simultaneously monitoring a person's body temperature and respiration rate by arranging optical sensors such as optical fibers and fiber gratings on the smart clothing. Background technique [0002] Respiration, blood pressure, pulse, and heartbeat are the four basic physiological characteristics of a person. These four physiological characteristics can reflect a person's health status. Therefore, devices and methods for detecting these physiological characteristics have been widely concerned and researched. Existing methods and devices for detecting physiological characteristics mainly use electronic technology or photoelectric combination technology, and there is no physiological monitoring device based on the principle of all-optical technology. [0003] Optical fiber and fiber Bragg grating (FBG) sensors have light weight, simple st...

Problems solved by technology

There are two deficiencies in this patent. One is that a film that can sense changes in breathing is required, which increases the difficulty of material selection, and the installation of the film also complicates the manufacturing process; the other is that the front end of the device uses LED and photoelectric detection. device, which greatly limits his scope of use, for example, the device may fail in a strong magnetic field environment

[0006] Although the above invention patents can realize the monitoring of body temperature or respiration, they have some defects. For example, active electronic devices are required for the sensing front end, because active electronic devices will fail under electromagnetic interference, especially in the presence of strong magnetic fields in outer space. In the environment, the use of active electronic devices is severely restricted, which makes it extremely unreliable for detection equipment to work in a strong magnetic field environment; moreover, these monitoring methods can only monitor a single physiological information, and in use not comfortable enough
