Coupling system and coupling method and process of Sweating Thermal Manikin and human body thermal response model

The invention relates to the technical field of public safety human body protection, in particular to a coupling system and a coupling method of a Sweating Thermal Manikin and a human body thermal response model.

Background technique:

Protective clothing is the necessary protective equipment for firefighters during fire fighting and rescue. The main functions are heat insulation, waterproof, and preventing the erosion of harmful substances, so as to achieve the purpose of protecting the lives of firefighters. However, due to the characteristics of multiple layers and strong airtightness of protective clothing, the heat exchange between the human body and the environment is hindered, resulting in a large amount of metabolic heat accumulated in the body and unable to be lost to the environment, resulting in increased body temperature, increased sweating, and heart rate. Accelerate heat stress and other phenomena, and cause cardiovascular system and nervous system diseases in severe cases.

In related technologies, such as medium sweating dummy system, body model thermal dummy system, thermal dummy system, etc., although it can simulate human body metabolic heat production and can collect and control parameters such as dummy temperature and sweating amount , but it can only be used passively to study the heat exchange between the human body-clothing-environment, the measurement of clothing thermo-humidity performance, heat transfer coefficient, etc. It should be noted that the thermophysiological response of the human body is affected by the parameters of the human body-clothing-environment. The existing dummy system can simulate the heat produced by the human body and measure the heat exchange between the human body and the environment, but it does not have the thermophysiological regulation function of the human body and cannot Like humans, they can sense changes in the environment and make active adjustments. Therefore, the existing dummy system cannot solve the thermophysiological changes of the human body under the working condition of wearing protective clothing.

Technical realization elements:

The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

Therefore, an object of the present invention is to propose a coupling system between the Sweating Thermal Manikin and the thermal response model of the human body, which can enable the dummy to actively adjust according to changes in the environment and meet the needs of protective equipment testing and research and development.

Another object of the present invention is to propose a coupling method of Sweating Thermal Manikin and human body thermal response model.

In order to achieve the above purpose, an embodiment of the present invention proposes a coupling system between Sweating Thermal Manikin and the human body thermal response model, including: the human body thermal response model, which is used to obtain the human body according to the amount of heat exchange between the human body-clothing-environment Skin temperature and sweating amount of each section; Sweating Thermal Manikin, used to regulate skin temperature and sweating amount, and measure the heat exchange between the human body and the environment to provide the human body-clothing-environment for the human body thermal response model The amount of heat exchange between them; the human body thermophysiological parameter prediction module is used to obtain the human body thermophysiological parameters through the coupling of the Sweating Thermal Manikin and the human body thermal response model.

The coupling system of the Sweating Thermal Manikin and the human body thermal response model in the embodiment of the present invention can input parameters such as ambient temperature, humidity, wind speed, and human metabolic heat production into the system, and obtain the heat and moisture exchange amount between the human body and the environment, the human body parameters such as skin temperature, core temperature, and sweating volume, and then evaluate the thermal comfort and thermal stress of the human body; The active adjustment function can perform real-time feedback and changes according to changes in environmental conditions; it solves the real-time prediction of thermal physiological parameters and the test of the performance of protective clothing under the condition of human body wearing protective clothing under different environmental conditions The testing and research and development of protective clothing and the prediction of thermal physiological parameters of firefighters provide a theoretical basis, and ultimately achieve the goal of ensuring the safety of firefighters, improving the efficiency of firefighting and rescue, and reducing casualties.
