"Snake Eyes" is a search instrument, its scientific name is "optical life detector", is the use of light reflection life detection instruments. The main body of the instrument is very flexible, like a sewer with the snakeskin tube, can be freely twisted in the rubble. Instrument in front of a tiny probe, can go deep into the tiny crevice detection, similar to the camera instrument, the information will be transmitted back to the rescue team members to use the viewer can be deep in the rubble to see the situation clearly.
In addition, the optical life detector on the probe can be rotated 360 degrees, as long as there is a finger-thin eye on the rubble, the optical life detector can be stretched into the probe rotated below the image will be transmitted up to basically determine the location of the buried people and trapped terrain, in the actual rescue can be not hurt by the buried personnel.
Thermal infrared life detector: in the dark can also work
Thermal infrared life detector with night vision, it is the principle of sensing the temperature difference to determine the different targets, so in the dark can also work as usual. The infrared life detector is very accurate in sensing whether a person is alive or not, ensuring that no survivor is missed if there is only a glimmer of hope.
It is perfectly suited to help rescue teams locate victims in or around debris-affected areas. It detects and displays heat from the victim's body to help rescue teams quickly locate victims buried under rubble or hidden behind dust and fog, and can withstand the harsh conditions of the rescue site.
Thermal infrared life detector can also be used to detect the distribution of hidden fire areas in underground coal mines, the location of fire sources, and also non-contact detection of underground central and mining area substation of all kinds of switches, connectors, transformer accident potential, water pumps, explosion-proof motors and power equipment (power cables) of the temperature, the heat state of the conveyor and transport belt.
Sonic life detector: can explore the weak sound
Sonic vibration life detector to find life by recognizing the sound issued by the trapped. Humans have two ears, this instrument has 3-6 ears, it is called "pickup vibration", also known as vibration sensors, it can be based on each ear to hear the sound of the successive small differences to determine the specific location of survivors.
The sound of speech is the easiest for it to recognize, because the designers have studied the frequency of human voice. If a survivor is no longer able to speak, he or she can be heard by tapping his or her finger to make a small sound. Even if a buried person is trapped under a large, fairly tight concrete slab, as long as the heart is still faintly fluttering, the detector can sense it, so the rescue team can determine whether anyone is alive under the rubble.
Search dogs: the most "intelligent" searchers
The above search instruments are more advanced internationally, but they are not the most "intelligent" searchers, on the basis of the National Rescue Team and part of the provincial (municipal) rescue teams. Also introduced a number of special "team members" - search dogs. After professional training, they have become a hundred percent of the search connoisseurs.
The dog's ability to recognize odors is a million times higher than the human, hearing is 18 times the human, not only a broad field of vision, but also the ability to see in low-light conditions, it is generally recognized internationally as the best search and rescue effect "equipment". Search with dogs is one of the most effective methods of on-site search, experience has shown that: with manual 30-60 minutes to complete the search, with dogs only 5-10 minutes. In a certain location, if two consecutive search dogs have not found survivors, it can be 100% assumed that there will be no survivors in the area. Of course, the dog search is not "everything", in the use of dog search, should pay attention to the wind direction. Sometimes search dogs can only tell you that there are survivors, but can not tell you the exact location, this time should be combined with electronic equipment for accurate positioning. In addition, the search dog on the odor of the higher requirements, the scene of chemical substances, rotting corpses, summer disinfection pesticides, etc. will be searching for the dog's work to interfere.
