With the development of science and technology, the research and development of intelligent clothes are more and more concerned. Smart clothing is a product of the integration and intersection of electronic information disciplines, materials disciplines, textile disciplines and other related disciplines. The intelligent garment can be used for monitoring the change of the external environment or the internal state of the human body, and the application scene is very wide. For example, in one application scenario, temperature monitoring may be performed for a user through a smart garment incorporating a temperature sensor.
According to data statistics, the current equipment conditions of firefighters in China are relatively poor, the firefighters wear the heat-insulation protective clothing more when fighting fire in a fire scene, the fire scene environment is not obviously sensed by the firefighters due to the sealing and material problems, and when the life is possibly threatened due to insufficient visual observation of small changes in the surrounding environment, unnecessary casualties are possibly caused due to the fact that the firefighters do not obviously sense the fire scene environment. Therefore, the fire-fighting uniform with the temperature monitoring function can help the firefighter and the command dispatcher to better sense the fire scene environment, and is also helpful for the command dispatcher to better command and dispatch, so that the life safety of the fire scene personnel is protected.
There are currently about 50 countries around the world in which sensor development and production is practiced, and there are many types of temperature sensors on the market, including bimetallic, glass liquid, pressure, resistance and thermal sensors. There are many temperature sensors that are suitable for use in high precision and high reliability applications. For example, the DS18B20 temperature sensor manufactured by DALLAS corporation, compared with the conventional thermistor, can directly read the measured temperature and can realize the 9-12 bit digital value reading mode through simple programming according to the practical requirement, and can complete the 9-bit and 12-bit digital values within 93.75ms and 750ms respectively.
However, attention is also paid to how to combine the temperature sensor with the fabric, and in the prior art, electronic elements such as the sensor are usually mounted on the fabric of the garment, so as to manufacture the intelligent garment. However, the combination of electronic components with garments has various problems. First, the electronic components are not miniature enough in size, give a foreign body sensation when installed on the garment, and cannot achieve the effect of flexibility in nature, and also affect the data actually detected by the sensor. Secondly, the functionality of the module is not strong, the measurement precision and accuracy do not meet the relevant requirements, and sometimes the deviation between the measured data and the actual situation is large, so that the real requirement of a user cannot be met. Third, the wearable device does not form a system and resource integration is to be enhanced. Most of intelligent clothes, the realization of functions thereof all emphasize data as a center, mainly focus on the analysis, processing and synthesis of data, but because the data integration modes and standards of all data analysis platforms are different, the analysis results are diversified; data analysis results of the platforms cannot be used mutually, so that information cannot be reasonably utilized, output data lack effectiveness, the output data are not beneficial to visual analysis, and better user experience effect cannot be brought. In summary, the problems in the prior art are that the beauty of the garment is affected by directly mounting the electronic elements on the garment fabric, and the wearing experience of the user is affected by the foreign body sensation caused by the electronic elements such as the temperature sensor; in addition, most electronic elements cannot realize flexible sensing, and the accuracy of detection data cannot be guaranteed; meanwhile, the output data is not beneficial to visual analysis, and the user experience is also influenced.
In order to solve the problems in the prior art, the invention provides a temperature monitoring intelligent fabric, which comprises a fabric and a plurality of quasi-distributed temperature sensors, wherein the temperature sensors are implanted into the fabric through a three-dimensional weaving method, and the fabric at least comprises two layers of weaving structures.

In this embodiment, the temperature sensor 12 is a flexible temperature sensor, and specifically, the form of the temperature sensor 12 is very similar to the textile fiber of the fabric 11, so that the temperature sensor 12 and the fabric 11 can be well combined without causing a foreign body sensation, thereby achieving the characteristic of flexibility. Meanwhile, the temperature sensor 12 is woven into the fabric 11, so that the purpose of hiding the temperature sensor 12 can be achieved, and the beauty of the fabric made of the intelligent temperature monitoring fabric 1 can be improved. The three-dimensional woven fabric is mainly made by a multi-warp weaving method, in this embodiment, the three-dimensional woven fabric may include an inter-wall integration method and a cross-wall integration method, and during actual use, other integration methods may also be included, which are not specifically limited herein.

The FBG sensor may be hung in the optical fiber 13, so that the FBG sensor (i.e., the temperature sensor 12) is combined with the fabric 11 by weaving the optical fiber 13 with the fabric 11. The foreign body sensation of the temperature monitoring intelligent fabric 1 is reduced by utilizing the flexibility characteristic of the optical fiber 13. The multipoint fiber Bragg grating sensing area is an area for temperature sensing which is composed of sensing areas corresponding to all fiber Bragg grating sensors.

Specifically, the optical fiber 13 is very similar to a conventional textile fiber, and the optical fiber 13 may be coated with a skin-friendly coating to reduce the foreign substance sensation of the optical fiber 13. Further, the optical fiber 13 may be coated with a fireproof or waterproof coating material to achieve the fireproof or waterproof effect.
In order to implant the optical fiber 13 into the fabric 11 without damaging the optical fiber 13 and the temperature sensor 12, and to make the optical fiber 13 and the fabric 11 well combined, and reduce the foreign body sensation, the optical fiber 13 and the fabric 11 are woven and combined by using a three-dimensional weaving method in the present embodiment. Finally, the fabric 11 is smooth in appearance, the temperature sensor 12 and the fabric 11 form a unified whole, the temperature sensor 12 hidden in the fabric 11 is difficult to find from the appearance, and the comfort and the aesthetic feeling of the fabric are improved.
