Life detection system drilled to the ground under the rubble of the ruins of the building than the dog's sensitive building collapsed, search and rescue dog hunting is not necessarily ten stable. In order to determine the specific orientation of the trapped people under the collapsed building, the first "life detection system" in China went into battle. The so-called "three brothers" system has the advantages of wind ears, perspective eyes and body temperature sensing. A few days ago, this "life detection system" undertaken by the Seismological Bureau of Sichuan Province took over the main development work and passed the acceptance by the Ministry of Science and Technology. Peng Jinchuan, senior engineer of the Provincial Seismological Bureau, described the skills of the “Life Detection System” to reporters. Drilling in the field has gone through the dog search. "The life detection system has the same skills as a search and rescue dog. Moreover, it has the ability to match rescue dogs." Peng Jinchuan, head of the earthquake rescue life search system, said, " In the event of an earthquake disaster, even a top search and rescue dog must rest for 30 minutes to an hour or so. After this period of time, the search and rescue dog's olfaction acuity will be greatly reduced, especially in the case of smoke. Search and rescue dogs are more difficult to function. This is the time when the life detection system is showing its glory."

Life detection system is not afraid of dust, fear of darkness, can enter the ground, can drill. When human beings and dogs are unable to work, they can enter and exit freely, quickly transmit the information they have detected to imaging personnel, and make rescue work quick. This life detection system has been successfully developed for the first time in China. It is not only suitable for natural disasters such as earthquakes and collapses, but also applies to mine rescue, military rescue, and anti-terrorism incidents. Listen to the sound of the three brothers of different skills The life detection system for the optical probing device, sound / vibration probing device, infrared thermal image "three brothers." Each of these “three brothers” has its own set of skills. The “optical probing device” is the “perspective eye” and can find trapped people in the ruins 20 meters underground. Its "big eyes" are 3.2 centimeters in diameter. With a turn of the eye, they can see the circa 127 degrees of things and then quickly transmit all the sights they "see" to the ground staff. "The 'boss' can not only detect life, but also can reflect the dangerous situations around the trapped people with pictures, which is more conducive to the organization of rescue." Peng Jinchuan praised the "boss". The "second brother" and "three younger brothers" each have their own skills. In particular, the "brothers" of the "wind ears", its scientific name is called the sound wave / vibration detector. The range of human hearing is only 500 to 800 Hz, and the "wind ear" can clearly hear any sound from 0.1 to 3,000 hertz. "Even if you drop the needle on the street, it can be heard against the ground," said Peng Jinchuan. The function of "wind ears" is to use sound waves and vibrations to detect life. Just put a thing like a doctor's "stethoscope" on the ground. "Good wind ears" can clearly hear the distress signals sent by trapped people underground. The "third child" mainly uses infrared rays to explore the body temperature of trapped people and form an image outline.

The visual life detector is equipped with fire-fighting equipment. It looks like a miniature assault "gun" and a "long" monitor on the "gun" rod. The shape is weird. It can be called the world's most advanced visual life detector equipped with Chengdu fire fighting equipment. . The SEARCHCAM visual life detector is a U.S. imported product worth more than 200,000 yuan. It is a special tool used by rescuers to search for people in distress under collapsed buildings and in narrow spaces, enabling the rescue team to act more quickly and safely. The upper body of the equipment is equipped with a headphone, a rocker, a control handle, and the display on the joystick clearly shows the front image. The camera installed at the probe of the detector can be rotated automatically. Once the light from the rescue is dim, the light can be turned on. The detector also has a major function, which allows the command to learn about the dangers of the first time. In combat, the detector extends up to 2.5 meters.
