| 摘 要： | 输油管道或暖气管道埋在地下,其巡线和定位检测是比较困难的.由于管道内的流体具有一定温度,并且温度可以通过热交换的形式传导到地面上产生红外辐射,因此可以采用红外探测器对地表温度进行测量,检测地表所发出的红外线并以红外热图的方式显示出人眼看不见的信息.根据地表温度差来判断出地下管线的走向,为地下管道的寻迹与维护提供了一种有效的方法.

| Abstract: | The oil underground pipelines or flue underground pipelines are difficult to be examined and sited. The fluid in the pipes has a certain temperature and the temperature can conduct to the surface of the soil, so a thermal infrared sensor to measure the temperature of the soil surface can be used. The detector can examine the infrared energy and display the thermography that can provide very detailed images of situations invisible to the naked eye. The site and the direction of the pipelines can be judged by the difference of the soil surface temperature. It provides an efficient method to search and maintain the pipelines underground. |
