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 thermal protective clothing, the flash heat exposure time is usually 4s, and the average heat flux density of thermal exposure is 84kW / m 2 . 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...

The invention relates to a three-dimensional human body burn algorithm considering skin thickness distribution. The three-dimensional human body burn algorithm includes the steps of obtaining data such as human body surface morphology and thickness of each layer of skin according to a target population, and dividing a human body region; utilizing a sensor or a numerical simulation method to obtaina target human body surface thermal response data; based on skin thicknesses of different regions and thermophysical parameters, taking the human body surface thermal response data as an input parameter, and establishing a skin internal heat transfer model and performing calculation, and obtaining an internal temperature field of skin at each part; extracting a key skin layer interface temperature, calculating a burn integral, and determining a burn grade; performing skin burn prediction on all the human body regions, calculating a burn grade ratio, and generating a human body burn distribution diagram and a burn evolving curve, to implement three-dimensional human body burn visualization. The three-dimensional human body burn algorithm can achieve three-dimensional human body accurate burn prediction and visualization and is suitable for various complex high temperature environments, and a human body region division mode can be adopted flexibly according to different populations.
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...
