Description

Technical Field

[0001] This utility model belongs to the field of clothing insulation testing technology, specifically relating to a clothing insulation performance testing device based on optical fiber. Background Technology

[0002] The thermal insulation performance of clothing is generally monitored using a prosthetic model, on which point-type temperature sensors are placed for monitoring.

[0003] Chinese invention (application number CN201811428203.5) discloses a temperature-sensing-based device and method for detecting the dryness of clothing. The device is characterized by comprising a temperature sensor, a fan, a drying heating rod, and a washer / dryer inner drum. The temperature sensor includes a first temperature sensor T1, a second temperature sensor T2, and an inner drum temperature sensor Tn. The first temperature sensor T1 is placed at the air inlet position at the rear end of the heater at the front of the fan, the second temperature sensor T2 is placed at the air outlet position at the front end of the drying heating rod, and the inner drum temperature sensor Tn is located inside the inner drum. This invention is low-cost, simple in structure, and reliable in operation. It can effectively protect different types of clothing during the drying process and effectively avoid wrinkles and damage to clothing caused by excessive drying time.

[0004] In actual testing, it was found that the technology uses multiple temperature sensors to achieve quasi-distributed measurement, which affects the measurement accuracy. Furthermore, the electric temperature sensor is at risk of failure in humid environments. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a fiber optic-based clothing thermal insulation performance testing device to solve the problems in the background technology.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A fiber optic-based clothing thermal insulation performance testing device includes a test vest and a test host. The test vest includes an outer layer, a middle layer, and an inner layer. A temperature-sensing fiber is provided on the inner side of the middle layer. The test host is connected to a transmission fiber. The temperature-sensing fiber and the transmission fiber are connected through a fiber optic connector.

[0008] Preferably, both the outer and inner layers are made of materials with good temperature transfer properties.

[0009] Preferably, the temperature-sensing optical fibers are arranged in a U-shape, and the spacing between the temperature-sensing optical fibers is 1 cm.

[0010] Preferably, the inner and outer layers are connected by needle and thread stitching, and the needle and thread stitching path is consistent with the laying path of the temperature-sensing optical fiber.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] By adopting a passive structural design, that is, without point sensors entering the inner layer to detect temperature, it can prevent malfunctions such as electromagnetic interference and water leakage burning out the sensors. The detection structure is safer, and temperature can be distributed to monitor the temperature in different parts of the clothing in real time. Furthermore, the temperature data measured on a single optical fiber are calibrated using the same standard to ensure data consistency. Attached Figure Description

[0021] Example 1:

[0022] like Figure 1-3 The invention relates to a fiber optic-based clothing thermal insulation performance testing device. The device includes a test vest 1 and a test host 2. The test vest 1 comprises an outer layer 4, a middle layer 6, and an inner layer 5. A temperature-sensing fiber 7 is disposed on the inner side of the middle layer 6. The temperature-sensing fiber 7 is connected to a transmission fiber 9 via a fiber optic connector 8. The transmission fiber 9 is connected to the test host 2. Both the outer layer 4 and the inner layer 5 are made of materials with good temperature transfer performance. The outer layer 4 and the inner layer 5 can quickly conduct the temperature of the clothing surface and its contact environment to the temperature-sensing fiber 7 in the middle layer 6, accelerating the temperature transfer rate. The temperature-sensing fibers 7 are arranged in a U-shape with a spacing of [missing information]. A 1cm spacing allows for full-area temperature measurement, effectively eliminating blind spots and significantly improving spatial resolution. This enables more accurate capture of temperature differences in different areas of the test vest 1. The inner layer 5 and outer layer 4 are connected by needle and thread stitching, with the stitching path consistent with the deployment path of the temperature-sensing optical fiber 7. This physical fixation ensures that the temperature-sensing optical fiber 7 does not shift during clothing deformation, washing, or daily use, maintaining the stability of the temperature measurement point position. Furthermore, the stitching tension prevents excessive stretching of the optical fiber, protecting its structural integrity and extending its service life.

[0023] Working principle:

[0024] When the test vest 1 comes into contact with the human body or is in a specific environment, the outer layer 4 and the inner layer 5, made of materials with good temperature transmission performance, can quickly receive temperature signals from the body surface, the environment, or the clothing itself. Through the thermal conduction of the materials, the temperature information is quickly transmitted to the temperature-sensing optical fiber 7 in the middle layer. The light signal inside the temperature-sensing optical fiber 7 will change its characteristics due to temperature changes. These light signals carrying temperature information are transmitted through the optical fiber connector 8 to the transmission optical fiber 9 and then to the test host 2. The test host 2 analyzes and processes the received light signals and, combined with the U-shaped layout information of the temperature-sensing optical fiber, can accurately analyze the real-time temperature data of each part of the clothing, thereby realizing distributed and real-time monitoring of the temperature of different parts of the clothing.
