通过对环境变化时墙体红外检测进行实验分析,及对墙体接收太阳辐射强度进行理论推导,并借助临界辐射强度分析,得出外墙缺陷红外检测的最佳时段,推导出可求得任意地域、季节和朝向条件下墙体接收太阳辐射强度变化曲线的公式,通过数值模拟得到墙体接收太阳辐射的临界强度。
Through the analysis of the infrared detection of the wall when the environment changes and the theoretical derivation of the solar radiation intensity of the wall, and by means of the analysis of the critical radiation intensity, the optimal period of the infrared detection of the external wall defects is deduced, , Season and orientation of the wall to receive the formula of solar radiation intensity curve, the numerical simulation of the wall to receive the critical intensity of solar radiation.
