In this era where every second counts, every fire rescue is a race against life. With the continuous innovation of science and technology, traditional rescue methods are being replaced by intelligent and high-tech rescue methods, which greatly improves rescue efficiency and safety.
Now, a revolutionary technology fusion is quietly changing this field - the "powerful combination" of gated imaging and infrared thermal imaging has brought unprecedented "perspective" capabilities to fire rescue, so that every life has more hope to be saved in time!
01
Limitations of traditional fire rescue
Traditional fire rescue methods are often inadequate in the face of complex fire scenes. Especially in special environments such as high-rise buildings and underground spaces, due to low visibility and rapid fire spread, it is difficult for rescuers to accurately judge the fire situation, which not only increases the difficulty of rescue, but also poses a serious threat to the life safety of rescuers.
02
Applications and limitations of infrared thermal imaging technology
As a mature technology widely used in the field of fire rescue, infrared thermal imaging technology can determine the location of the fire source and the direction of fire spread by detecting thermal radiation, detect temperature, and even search and rescue trapped people through smoke. However, in the face of high-temperature flames and smoke, infrared thermal imaging technology has limited penetration ability, and it is difficult to penetrate obstacles such as glass, which limits its application effect in complex fire scenes to a certain extent.
In indoor fires, infrared thermal imaging technology can assist rescuers to determine the location of the fire and the direction of fire propagation, but due to the complexity of the indoor environment, such as the accumulation of smoke and the existence of obstacles such as glass, the application effect of infrared thermal imaging technology is limited. This is where the advantages of gated imaging technology come into play.
In forest fires, infrared thermal imaging technology can help rescuers determine the location of the fire source from the air or from a distance, but due to the particularity of forest fires, such as the rapid spread of fire and the depth of the fire, infrared thermal imaging technology also faces the problem of insufficient penetration.
03
Benefits of gated imaging
As an emerging technology, gated imaging technology can effectively eliminate the interference of smoke and background clutter and improve the imaging quality by emitting laser pulses and controlling the electronic shutter of the receiver. Its near-infrared laser is able to penetrate the glass and observe the situation behind the obstacle, providing clearer on-site information for fire rescue.
In indoor fires, gated imaging can provide clearer images than infrared thermography, especially in smoky environments. It is able to penetrate smoke and provide the accurate location of trapped people and fire sources, greatly improving the efficiency and success rate of rescue.
In forest fires, gated imaging technology can also provide clear fire images, help rescuers determine the location of the fire source and the direction of fire spread, especially in the case of rapid fire spread and large fire depth, gated imaging technology can provide more accurate fire information to guide rescue operations.
04
The potential for the combination of technologies
Combining gated imaging with infrared thermography allows you to take full advantage of the advantages of both and overcome their limitations. Infrared thermography provides preliminary information on the source of fire and temperature distribution, while gated imaging provides clearer details of the scene and the location of trapped people. This combination of technology not only improves the accuracy and efficiency of rescue, but also provides a stronger guarantee for the safety of rescuers.
05
Combined with the economic benefits of the application
Through the combination of technology, fire rescue teams can obtain more comprehensive information about the fire scene, achieve more efficient rescue operations, and reduce casualties and property losses. This convergence of technologies has significant economic benefits, keeping rescuers safe while minimizing fire damage.
conclusion
The combination of gated imaging technology and infrared thermal imaging technology has brought new perspectives and solutions to the field of fire rescue. This kind of technology integration not only improves the accuracy and efficiency of rescue, but also provides a strong guarantee for the safety of rescuers, which has important practical application value. With the continuous progress and improvement of technology, we have reason to believe that the future of fire rescue will be more intelligent and efficient, and contribute more to the safety of human society.
In order to more intuitively show its application potential and importance in fire rescue. Next, let's take a look at a series of scene tests conducted by gated imaging technology in the field of fire protection~
Test 1
1) Combustibles material: wood stack fire;
2) Environment: 2 lit vertical stacks of 0.5*0.5*0.5 wooden stacks;
3) Equipment: gated image enhancement CMOS camera, laser pulse light source;
4) The camera is 12m away from the wooden stack, the depth of the fire site is about 1.5m, the target distance from the wooden stack is 38m, 19m, 3m respectively, and the angle of the laser collimator is set to about 3 degrees;
5) Using the time-lapse push-broom function, the delay between the laser light time and the camera opening time when the target distance is 38 meters, 19 meters, and 3 meters respectively is determined by analyzing the intensity curve;
6) The imaging effect is as follows:
7) Test summary: Laser distance gating technology can realize penetrating flame and smoke imaging to meet the rescue effect. In the face of different target distances, the more concentrated the beam energy, the better the flame penetration effect.
Test 2
1) Incendiary material: heptane fire;
2) Environment: 1.5m diameter, 15L oil pan;
3) Equipment: gated image enhancement CMOS camera, laser pulse light source;
4) The camera is 12m away from the flame, the flame is 1.5m deep, and the target distance is 19m
5) The imaging effect is as follows:
6) Test summary: Compared with the wood stack fire, the smoke generated in the face of n-heptane fire is large, and the penetration effect is worse than that of the wood stack fire.
Test 3
1) Environment: The test environment is an indoor closed environment, the target is placed in front of the camera and the light source, the smoke cake is lit and the smoke cake is filled until the smoke is gradually dispersed from the top of the room to the floor of the room, at this time, the visible light camera of the same height and the same angle angle cannot observe the target, and the smoke is judged to be nearly uniform, and the visibility is about 0.9m at this time;
2) Equipment: gated image enhancement CMOS camera, laser pulse light source;
3) The distance between the target and the camera is set to 2.7m
4) Test results: It can achieve smoke transmission imaging effect.
5) The imaging effect is as follows: the smoke produced by the smoke cake is not the same as the smoke produced by the actual fire, and the particle size is not the same, which has a certain impact on the smoke penetration imaging effect.
Through the above sets of tests, it can be seen that the gated imaging technology can effectively suppress the interference of fireworks and effectively image the target in the fire environment. At the same time, it also shows that its main function is to image people or objects in the fire field, and the smoke and smoke itself are not the object of observation of this technology.
