Thermal imaging cameras are excellent building inspection tools that effectively detect building quality problems such as empty drums and leaks without posing any risk to the building itself. Building inspection requires an infrared camera to be extremely sensitive. Because the temperature difference to be found is very small, you need an infrared camera that can detect the most subtle temperature changes and temperature differences. Detection principle: The wall structure has a large heat capacity, and if the surface material is peeled off, the heat conduction between the outer wall and the body becomes small. Generally, when exposed to sunlight or warmed air, the temperature of the surface of the outer wall rises, and the temperature of the peeling part is higher than the temperature of the normal part; on the contrary, when the sunlight is weakened or the temperature is lowered and the surface temperature of the outer wall is lowered, The temperature of the peeling site is lower than the temperature of the normal portion. Test case: A municipal engineering company in South China needs to repair the problem of the external wall surface falling off of a residential area. The community is very large. It is difficult to find the problem points quickly and accurately, and repair the problem points. The method used before is to use bamboo poles to strike. There is a problem with both detection efficiency and accuracy. The scene shown in the thermal image is the second repair work of the community. Difficulties in testing: 1. The temperature difference on the surface of the building is usually very small, around 3 degrees. In particular, the day of the photo is cloudy, the wall lacks a significant warming and cooling process, so it needs sufficient thermal sensitivity to distinguish the small temperature difference. The thermal sensitivity of the Fluke master's choice is as high as 0.03 °C, which can clearly show the subtle temperature change. 2, the community is a high-rise building, customers need a heat map to find all the problems of the entire building, then you need to be far enough away. The size of each brick on the wall is approximately 0.2 m * 0.4 m, and the area of ​​the empty drum will be smaller. Therefore, the ability of the thermal imager to detect small targets at a long distance requires a high IFOV parameter which will play a crucial role. Under the standard lens of Fluke Master, the IFOV reaches 0.6mRad, and the ultra-long-focus lens can reach 0.1mRad, which is a problem that can be resolved by 10cm outside 100m. 3. Ultra-long detection distance: 200 m away. On-site inspection notes: 1. Avoid real-time detection of direct sunlight. Sunlight is a high-temperature heat source, which will affect the test results. 2. The best detection time for sunny days is evening, and the outer surface of the building will generate heat dissipation and cooling process; 3, the best detection time on rainy days is the next morning, the surface heating process of the building, the wall surface is warmer than the water in the hollow drum; 4. Because the wall surface is a small target of temperature difference, in order to better find the problem, the upper and lower limits of the palette span can be shortened to the value of the actual temperature.
