The Spring Festival is gradually approaching, and many people can't wait for this reunion moment to arrive. However, it is worth noting that the Spring Festival is also a time of frequent fires, and fire prevention cannot be relaxed.
Editor: According to the information obtained by CCTV News from the National Fire and Rescue Administration on January 4, it can be seen that in 2023, the national fire and rescue team will receive reports and dispose of 21380,000 police cases of various kinds. Among them, 87 urban and rural fires were extinguished80,000, 156 forest and grassland fires, and 44 emergency rescues40,000 cases and 61 social assistance60,000 cases, 39 rescued and evacuated people50,000 people.
Editor: This year's total number of fires and fatalities are down year-on-year, respectively. 8%, it can be seen that China's fire rescue and disaster prevention and control capabilities are constantly strengthening.
However, the economic losses caused by the fire and the number of people** are still huge. It is important to know that the fire scene is mostly a complex environment where smoke and fire coexist, which not only affects the safety of the trapped people, but also threatens the fire rescue personnel who protect our safety.
Before the rescue, fire reconnaissance is the key to the success or failure of the fire fighting and rescue operation, and it is also the link with a high mortality rate for rescuers. Fire reconnaissance can accurately grasp the spread of fire, smoke distribution, possible dangers and trapped personnel in the fire scene.
At present, the main fire rescue reconnaissance equipment mainly relies on infrared thermal imagers, gas detectors, and life detectors.
Infrared thermal imaging is mainly used to search for trapped people inside buildings that have not been burned, or trapped people behind cold smoke. The reason why it is limited to unused fire and cold smoke is because the search and rescue of infrared thermal imaging relies on the blue color and high contrast picture to highlight the heat source, once the fire temperature is higher than the human body temperature, and the personnel are behind the fire source and smoke, it is very easy to be ignored. However, it still plays a huge role in fire direction reconnaissance, fire source reconnaissance, and fire prevention.
The gas detector is a detection step that needs to be done to prevent toxic and flammable gases from being dangerous in the fire scene. If it is safe to do so, you can continue reconnaissance at a deeper level.
The life detector is mainly aimed at the search for trapped people, based on the equipment for detection of certain characteristics of life, there are currently infrared life detectors, audio life detectors, radar life detectors.
It is important to note that all three types of equipment are designed to detect a certain feature. However, the problem of clear imaging through mixed environments such as high temperatures, smoke, and flames cannot be solved due to the limitations of technical characteristics. Once blindly entered, it will seriously threaten the life safety of fire and rescue personnel.
Therefore, in order to ensure the safety of fire rescue, the problems of penetrating flames and high-temperature smoke thermal imaging must be solved as soon as possible.
The original intention of the development of the penetration imager is mainly to solve the pain point that rescuers cannot see the real scene behind the fire, improve the efficiency of rescuers, and reduce the fear brought by the scene.
This new imaging equipment is still blank in China. The new optical imaging technology is used to break through the defects of passive imaging, and can suppress the ambient light up to 108, which can realize the imaging requirements of fire penetration, smoke imaging and fog imaging.
Editing this new imaging technology equipment will solve the current fire imaging problems, help rescuers see the real situation of the fire scene, provide effective data for fire reconnaissance and rescue, and then improve rescue efficiency. At the same time, it can effectively avoid the existence of dangerous situations such as stepping on the air and hitting due to unclear vision.
In the later stage, the penetration imager will be strengthened and upgraded in many aspects such as product miniaturization and imaging clarity to better protect the lives of rescuers and trapped people.
