First of all, let's look at the situation where there is no open flame at the fire site. In one case, the temperature of the dark fire has not reached the point where a large amount of combustible gas can be released quickly, so there is no obvious flame. Another situation is that the temperature of combustible materials is already high, but there is not enough oxygen, which leads to smouldering and releases a lot of smoke. Once the oxygen is sufficient, the fire develops rapidly. In some places, goods and articles pile up like mountains. At first, they may smoulder inside and emit thick smoke. This smoldering process may take a long time. By the time an open fire broke out, the fire was already very strong, and it was difficult to put it out in a short time, resulting in serious losses. There are flammable and explosive petroleum, coal and chemical products, and smoldering may also lead to explosion.
The detection and early warning of fire scene by automatic fire monitor is automatically started according to the detection of red and ultraviolet flame waves. Generally, red and ultraviolet flame sensors are used, and these sensors need an open flame to be activated. When there is no open flame at the fire site, the automatic fire monitor sensor will not give an early warning, so it will not start automatically and cannot extinguish the fire.
Is there a highly intelligent product on the market that can detect the fire source and automatically extinguish the fire even if there is no open flame at the fire site?
Indeed, Lianzong Fire Technology has developed a new type of intelligent water cannon. Through the self-developed eagle-eye patented "LINKZOOM" thermal imaging positioning technology and traditional red-ultraviolet flame detection technology, the five-fold technology upgrade of red-ultraviolet thermal imaging laser video was realized, which promoted the upgrading of automatic fire monitors and developed the second generation of intelligent fire monitors. In this intelligent fire monitor, a real-time temperature measurement signal with a field of view is added to the red ultraviolet detection technology. The thermal imaging detector for positioning has the functions of smoke penetration and temperature measurement, and can self-warn, detect and locate the real fire source by using function calculation through the temperature change of each pixel in the array, and implement fire extinguishing and water spraying. In the early stage of smoldering fire scene, before the appearance of open flame, the second generation intelligent water cannon developed by Lianzong Fire Technology can find the fire source according to the temperature of the fire scene. After the fire fighting operation, the ignition point of the open flame was put out. If there is still a dark fire source, the site temperature will not drop too much. The second generation intelligent water cannon will still find the dark fire point and put it out in time. Only when the open fire source is extinguished, the dark fire source is extinguished, and the temperature of the fire site drops, the water cannon will stop the fire fighting action and automatically turn off, thus realizing high automation and intelligence.
In this way, we can still start the water cannon automatically and put out the fire automatically when there is no open flame and smoke at the scene. Therefore, it can be seen that the ordinary automatic fire monitor on the market will not start to extinguish the fire without an open flame. Only the second-generation intelligent fire monitor with longitudinal fire fighting technology can automatically start fire fighting without open fire. I hope that when you choose a water monitor, you should fully consider your own fire-fighting needs and buy an automatic fire monitor with complete functions, more advanced technology and stronger fire-fighting ability.
