A system and working method for simulating human sweating under fire conditions

Abstract

The invention discloses a system and working method for simulating human body sweating under conditions of a fire scene, including an artificial environment cabin, a warm body dummy, a motion system, a temperature control system in the cabin, a wind speed simulation system and a control center; the motion system is used for Simulate different motion states of the human body, the temperature control system in the cabin is used to simulate the temperature of the fire scene, the wind speed simulation system is used to simulate the wind force of the fire scene, and the thermal manikin is used to simulate the actual sweating of various parts of the human body; Under the influence of motion state, different fire environment temperature and different wind force on the change of fire environment temperature field distribution, the sweating amount and sweat flow distribution of each part of the thermal manikin can be obtained, so as to provide data for the subsequent layout of sweat-absorbing materials in firefighting clothing For reference, the sweat of different parts of firefighters can be absorbed in time when they are rescued in the fire scene, so as to ensure the rescue ability of firefighters.

Description

technical field [0001] The invention relates to a system and a working method for simulating sweating of a human body, in particular to a system and a working method for simulating sweating of a human body under fire conditions. Background technique [0002] Thermal manikin is an instrument that simulates the heat and moisture exchange between the human body and the environment. It is a new biophysical test method gradually developed in the 1940s. Its body size is similar to that of an ordinary adult. With the development of science and technology, thermal dummies fit more and more closely with humans. At present, there are radiation dummies, combustion dummies, single-section dummies and multi-section dummies, etc. Khan's thermal manikin has been less studied. Among them, the Chinese patent with the publication number CN 105241914A discloses an inflatable sweating warm-up manikin, which is light in weight and stable in size, but its design is to make the temperature distri...

AI Technical Summary

Problems solved by technology

For example, when firefighters rescue a fire, the temperature of the fire and changes in motion will affect the sweating of different parts of the firefighters. If the sweating of firefighters under different fire conditions cannot be known, it will lead to After entering the fire scene for rescue, due to the deviation of the layout of sweat-absorbing materials, the sweat cannot be absorbed in time, thus affecting the rescue ability of firefighters in the fire scene

At present, there is no human dummy that simulates the influence of different motion states, different fire environment temperatures and different wind forces on the distribution of the fire environment temperature field, and obtains the sweating amount and sweat flow distribution of each part of the thermal manikin. , so as to provide data reference for the position layout of the sweat-absorbing material in the subsequent firefighting clothing, and finally enable the sweating of different parts of the firefighters to be absorbed in time when they rescue in the fire scene, thereby ensuring the rescue ability of the firefighters
