Embodiment Construction
[0039] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.
[0040] When firefighters carry out emergency rescue and disaster relief, they need to wear firefighting clothing to quickly pass through the fire scene. Firefighting clothing is an important barrier to reduce skin burns, but when the environment is harsh or the protection effect is insufficient, it will still cause skin burns to firefighters. When evaluating the protective properties of single-layer heat protective clothing, the flash heat exposure time is usually 4s, and the average heat flux density of heat exposure is 84kW / m2. Due to the unstable nature of the flame, different parts of the human body experience different heat fluxes at different times. In this case, accurate burn prediction can be performed on parts of the human body, and the distribution of burns throughout the body can be obtained. The invention can effectiv...

The invention relates to a three-dimensional human body burn algorithm considering the distribution of skin thickness. The steps are: according to the target population, obtain data such as the surface shape of the human body and the thickness of each layer of skin, and divide the human body area; use sensors or numerical simulation methods to obtain the target Human body surface thermal response data; based on the skin thickness and thermophysical parameters of different regions, the human body surface thermal response data is used as an input parameter, and the internal heat transfer model of the skin is established and calculated to obtain the internal temperature field of each part of the skin; the key skin layer interface is extracted Temperature, calculate burn points, and judge burn grades; predict skin burns for all human body areas, calculate burn grade ratios, generate human body burn distribution maps and burn evolution curves, and realize 3D visualization of human skin burns. The invention can realize accurate burn prediction and visualization of three-dimensional human body, is applicable to various complex high-temperature environments, and can flexibly adopt a human body region division method for different groups of people.
Description
technical field [0001] The invention relates to a three-dimensional human body burn algorithm, in particular to a three-dimensional human body burn algorithm considering the distribution of human skin thickness. Background technique [0002] The threat caused by the thermal environment to the human body is mainly skin burns. It is of great significance to effectively predict and strengthen the protection system to reduce skin burns. In the field of thermal protective clothing, the thermal protection performance of clothing is usually characterized by the skin burn rating or the time required to achieve a burn. In the medical field, effective prediction of heat transfer inside the skin is an important means of treating skin burns. Because burns can have destructive effects on the human body, it is difficult to directly apply heat sources to human skin through physical experiments to explore the mechanism of skin burns. The numerical simulation method can provide a reference...
