A few days ago, through the expert appraisal committee led by He Jishan, the academician of the Chinese Academy of Engineering, the "Ultra Wideband Radar Life Detector for Police" developed by Hunan Province officially passed the national scientific and technological achievement appraisal.
In the face of major disasters, how to quickly and accurately find the life signals buried in the rubble, concrete and other ruins, to save the lives of trapped people to the greatest extent, has been one of the technical difficulties of disaster relief work. In early 2009, the Fire Bureau of the Ministry of Public Security issued a key research project on "Ultra-wideband Radar Life Detector for Police", which was jointly developed by the Hunan Provincial Fire Brigade and Hunan Huanuo Xingkong Electronic Technology Co., Ltd. In response to some of the major technical deficiencies in current life detectors such as audio, optical, and infrared, researchers have successively conquered a series of key technologies and adopted a new system of ultra-wideband radar technology to achieve fast search and precise positioning of living bodies. The test results show that the device can effectively detect human body movements, heartbeats, breathing and other activities within a range of 20 meters.
It is understood that the device has successfully passed the earthquake simulation environment test of the State Seismological Bureau in April this year. Later, in the Yushu earthquake rescue mission, rescuers used the equipment to successfully detect and rescue many people. Experts believe that the equipment is at the domestic leading level in technology.
