Research on Parameter Setting Algorithm of Thermal Protective Clothing based on Image Processing Technology

对高温环境下经过热防护服传热到假人皮肤的整个热传导问题进行分析,建立热防护服各层厚度测量方法的数学模型。假定在皮肤外侧温度与时间关系的数据已知情况下,运用MATLAB软件,对皮肤温度与时间关系数据进行拟合,得到的拟合方程,绘制出整个传热模型过程的温度分布图;基于傅里叶定律和由能量守恒定律求得热平衡方程,计算出人体防热材料各层的最优厚度。该模型可作为高温坏境下测量热防护服各层厚度、预测人体热生理参数、评估舒适度和热传导实验的依据。

The whole heat conduction problem from thermal protective clothing to dummy skin in high temperature environment is analyzed,and the mathematical model of thickness measurement method for each layer in thermal protective clothing is established.Assuming that the data of the relationship between skin temperature and time is known,the MATLAB software is used to fit the data of the relationship between skin temperature and time and the fitting equation is obtained to draw the temperature distribution diagram of the whole heat transfer model process.Based on Fourier’s Law and the heat balance equation obtained from conservation of energy,the optimal thickness of each layer of human thermal protection material is calculated.The model can be used as a basis for measuring the thickness of each layer of thermal protective clothing,predicting human thermal physiological parameters,evaluating comfort and conducting heat experiments under high temperature environment.
