As shown in Figure 1 be arranged on intelligent monitor system in clothes: the front end of system is a space flight underwear arranging optical fiber grating and optical fiber, i.e. induction mechanism, rear end is demodulation module, reaction mechanism and a related software.Space flight underwear 1 arranges five optical fiber grating FBG6 ~ 10, these five FBG are stelliform connection topology configuration, are arranged in the left and right chest of space flight underwear, oxter, left and right and back five positions.These five FBG have passed through temperature sensitizing process, very high to the sensitivity of temperature.Five FBG are connected with the demodulating system of rear end by a coupler; the demodulated system acquisition of FBG reflected signal also processes the body temperature information obtaining astronaut; obtain body temperature information and will be sent to warning; if body temperature or breathing be not in normal scope; warning can give the alarm; notify that astronaut or surface work person make correct process timely, avoid dangerous generation, farthest the safety of protection astronaut and space equipment.
The monitoring of astronaut's respiratory rate is one section of curved fiber 12 realization by being arranged in space flight underwear abdominal region.This curved fiber 12, in sinusoidal, connect with an optical fiber grating FBG, and FBG can reflect self characteristic wavelength, and most energy still can continue transmit through grating.FBG reflects a narrowband wavelength, and this wavelength is his characteristic wavelength, and in addition the luminous energy of the overwhelming majority can continue forward direction through FBG.
The light of transmission has corresponding loss through curved fiber, and the size of loss is relevant with fibre-optical bending curvature, and the loss of the larger luminous energy of curvature of fibre-optical bending is larger, otherwise then less.When fibre-optical bending degree diminishes, waste of power diminishes, and the light intensity that detector detects becomes large, otherwise the light intensity that detector detects diminishes.
When astronaut puts on this intelligent underwear, first regulate the tightness of belly elastic webbing 11 according to own actual situation, make it wear comfortable, do not affect the normal work of astronaut.When astronaut regulate elastic webbing 11 position and make its be in the most comfortable state time, astronaut breathes the bending situation that can change and be sewn to curved fiber on elastic webbing each time, the waistline often inhaling a pneumoperitoneum portion can become large, corresponding elastic webbing is stretched, the curvature of curved fiber diminishes, the loss of light diminishes accordingly, and the transmitted intensity that demodulating system detects becomes large.When astronaut exhales, belly waistline diminishes, and elastic webbing shrinks, and be sewn to optical fiber bending curvature on elastic webbing and become large, optical signal loss increases, and rear end detector detects light signal energy and reduces.Therefore, the energy changing that monitoring system detects under normal circumstances can form a regular change.Once when astronaut runs into emergency case, when making his breathing become rapid or slow, the energy changing cycle that detector detects will change, when running into this situation, rear end reaction mechanism can send warning equally, prompting cabin in other cosmonaut even bottom surface engineer process emergency case in time, ensure astronaut's life security with this.
Light source and demodulation module can be arranged on the outside of craft's interior or space suit, transducing signal is transmitted by optical fiber, the object done like this is in order to avoid high-intensity magnetic field is to the interference of demodulation module and light source, and fiber transmission attenuation is little, short-range transmission can not affect the quality of optical signal substantially.
This FBG is through temperature sensitizing process, and temperature control is very high, and accuracy of detection can reach 0.1 DEG C;
Structure of the present invention is simple, and accuracy of detection is high, good reliability, diverse in function, and cost of manufacture is lower, wears comfortable novel intelligent clothes.This intelligent clothing is intended being used in field of aerospace, can detect body temperature and the respiratory rate of astronaut simultaneously, monitor in real time these two physiological characteristics of astronaut.
Although invention has been described for composition graphs above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; when not departing from present inventive concept, can also make a lot of distortion, these all belong within protection of the present invention.
