In the Sichuan earthquake, it was found that many rescuers used life detectors to search and rescue survivors. The author checked the relevant information and briefly introduced life detection. Information about the instrument:
The life detector is a safety and life-saving system recently launched by the American Supervision Safety System Company in 2005. David Cist, a well-known geophysicist and Ph.D. from the Massachusetts Institute of Technology, creatively applies radar ultra-wideband technology (UWB) to the field of safety and life-saving, thus bringing a revolutionary new technology to the field. The safety and life-saving system based on this new technology, the life detector, has successfully solved a number of problems that plagued traditional safety and life-saving systems, making search and rescue work faster, more accurate, and safer than ever before. It is now the world's leading safety and life-saving system. The most advanced life detection system. The antenna of this system is one of the two candidate radar antennas designated by NASA for the Mars rover. It is the most advanced ground-penetrating radar antenna in the world and can capture very weak movements very keenly. This product has received a US patent. Chaoshi Security System Company has recently launched this system simultaneously in China, the United States and Japan.
The life detector is actually a breathing and motion detector. The radar signal transmitter continuously emits electromagnetic signals and scans a certain space. The receiver continuously receives the reflected signals and performs algorithmic processing on the returned signals. If the subject remains stationary, the return signal is the same. If the target is moving, the signal is different. By comparing the signals received in different time periods and other algorithm processing, it can be judged whether the target is moving.
The life detector works by testing the breathing movement or movement of the person being detected. Because the frequency of breathing is low, usually 1 to 2 times per second, breathing movements can be distinguished from other higher-frequency movements. The principle of measuring movement is roughly the same. The antenna of Supervision Security Systems is one of the two Mars probe georadar antennas designated by the National Aeronautics and Space Administration (NASA). It can capture very weak movements very keenly. Coupled with powerful algorithm processing, it is a safe and life-saving The best helper in the department.
DKLLifeGuardTM life detector is currently the most advanced search and rescue instrument in the world. It is lightweight and only about 1 kg. It is handheld in design, easy to carry, simple to operate, and has superior performance to any other high-tech search and rescue products. It has been widely used by the military, customs, maritime patrol, firefighting, security, rescue, aerospace and other government departments of advanced countries in the world.
This product is a combination of the world's most advanced biochemical, Developed using dielectric, ultra-low frequency conduction and DNA technologies, it has applied for a number of technology patents. This model is currently the most mature product designed by DKL.
LifeGuardTM life detector provides rescue personnel with in-depth search and rescue services. When at the scene, first confirm whether there are people alive inside, reduce the risk of rescuers during search and rescue, and detect survivors behind any obstructions at the first time. Use passive reception to detect the weak heartbeat of the far-end dielectric field. direction, and only detects living humans without interference from other animals. It can pass through various obstacles such as steel plates, cement, composite materials, and trees, making the detection distance up to 500 meters in open space and up to 1 on the water.
