为分析不同应激条件下受限空间内人员疏散时间规律,基于受限空间环境与安全人工智能仿真试验系统,开展气体灭火剂IG541不同体积分数环境中人员生理影响试验研究,在某电子设备厂房人员进行了疏散试验,分析疏散时间与气体体积分数间相关关系。试验结果表明,随着体积分数增加试验对象心率显著加快;部分试验对象在体积分数为30%情况下出现窦性心律过速现象,体积分数超过30%时部分测试者舒张压超过90 mm Hg、收缩压超过120 mm Hg。疏散时间与灭火气体体积分数存在明显正相关关系。
The method of infrared thermography to predict the temperature of the sulfide ores has a large error. To solve this problem, the temperature of the sulfide ores is measured by thermal infrared imager and recording thermometric instrument contrastively. The main factors, including emissivity, distance, angle and dust concentration that affect the temperature measurement precision, are analyzed. The regression equations about the individual factors and comprehensive factors are obtained by analyzing test data. The application of the regression equations improves the precision of the thermal infrared imager. The geometric information lost in traditional infrared thermometry is determined by visualization grid method and interpolation method, the relationship between the infrared imager and geometry information is established. The geometry location can be measured exactly.
