Жизнь Обнаружение радар

Life detecting radar SJ-3000 is used in operation for victims and survivors in disasters, such as earthquake, land slides, underground constructions and criminal investigation. The radar combines ultra wide band wave radar technology and biomedicine technology ,with high penetration be able to detect the buried lifes characters such as breathe and body movement and precisely measure the distance and depth of the buried life and has high ability against interference. Compare to optical infrared and audio frequency detection technology, it is not affected by interference of environment temperature, thermal objects and voice.The life detecting radarhas advantages in terms of detecting position of survivals rapidly and without limitation of geographic conditions (ruins, smoke, mining collapse) and state of the survivals (wounds, unconsciousness).Our products improve efficiency of rescue service and providing chances for life saving, and has a wide application prospect. Components ofthe Life detecting radar SJ-3000 is made up of main body anddisplay controller : 1/Main body of the radar consists of antenna, transmitter, receiver, signal pre-treatment device, signal sampling slab, front end signal control system and power system, etc. mainly for emission of receiving of electromagnetic wave and pre-treatment to the received signals and data communication. 2/Display controller: To carry out remote wireless console and control to main body of radar by displaying controller and display rescue and detected result. Operation Theory Life detecting radarSJ-300 is of a new type, UWB (ultra wide band) life detection radar, combing life information treatment technology and UWB technology to detect targets by making use of its high penetration ability and non-contact detection features. Meanwhile, by using advanced life information treatment technology extract and identify life characterized information, thus achieving the purpose of searching human survivals. Function and Features SJ-3000 has following functions: High penetration ability:the radarhas strong penetration ability;detection distancefor soils,brick wall ruins, multi-layer reinforced concrete pre-cast slab ruins is 15m.Flexible applications: the radar can be used freely without limitation of geographicconditions, may be placed on ruins or put against wall along support frame, or suspended to detect all directions.High sensitivity: New biomedicine engineering technology is able to detect life in different postures ( such as lying on the side and lying face downward), especially be able to detect unconscious wounded persons vital signs such as breath and heart beat.Precise distance measurement: Unique P second grade pulse radar technology make resolution reach 10cm (correction value), thus to positioning the object and to detect distance information of living bodies, which is helpful for excavation and rescue.High anti-interference ability: A special practical technology is used to block all interferences to be received at complicated site.Ability to differentiate human being from animals: Be able to differentiate human being from some animals.Object bionic display: Displaying the detected living bodies on screen as humans eye bionic manner.Intelligent judgment: To judge existence of life bodies intelligently and give detected resultsautomatically.Quick response: To give the detected results within 30 seconds. Technical specifications Penetration ability: penetration depth of main body of theradar through ruins: 15mWireless communication ability: inside set wireless communication distance 50m;Working temperature: -15-+50Storage temperature:-20-+60 Short Setting up time: Unfolding time≤1min, Object responding time≤3s, Folding up≤1minResult display: Directly display detail position of the detected objectPower supply: field working time(inside set power), work continuously not less than10 hours Using ofLife Detecting Radar(The rescuer in Wenchuan earthquake) May12, 2008 when Wenchuan earthquake happened, Xian Biken Technology Development Co.,Ltd organized 5-person team spontaneously broughta Life detectingradar SJ-3000 with them joining Shaanxi rescue team to rush to serious disaster region- Beichuan County on May 13. The rescue team carried out our search and rescue radar in Qushan primary school, government office, kindergarten, market and other places immediately. Rescuers from Biken and Shaanxi rescue team together struggled against death. After 10 days tough working, they have made great contribution for rescuing of 21 persons life. On May 14th 13:25, rescuers from Xian Biken technology Co., Ltd and Shaanxi province rescue team arriving Beichuan Qushan Primary School for research and rescue survivors. After carefully searching, the radar found life information at 13:55. Rescuers took risk of aftershock to dig from broken tiles to save the luckily survived student. At 17:45, an 11-year old student was saved successfully.At 8 oclock May 15th, rescuers from Biken and Shaanxi rescue team arrived Beichuan ChinaMobile for search and rescue. At 11:40 the SJ-3000 radar found life information from 3 places, when rescue work was continuing till 5 oclock may 16th, detection was made again with the radarto make sure there is still one survivor. After 25 hours hard rescue work, till 9 oclock May 16th, the survivor finally has been saved and sent to medical treatment center.At 15:05 May 16th, when rescuers of Xian Biken search at entrance to Yang Jiao alley ruins, SJ-3000 display controller displayed that there was signs of life, after further detection to make sure the location of the survivor, and contacted Shaanxi rescue team and started to rescue at 15:35. Around 19:00, till concrete beam and pre-cast slab were hang away by crane. 23:30, the survivor who buried under ruins for 100 hours was successfully saved.Yangjia Street Market in Beichuan County is one of the most serious disaster places, which was buried under buildings completely. Buildings in front and behind disappeared. Everyone was shocked for this. 9:00 oclock 17th, Biken rescuers received the order to detect this place. At that time gold time has passed, however, rescuers still detect carefully. Around 15:00, after 6 hours continuing detection with SJ-3000, life signal was found in a narrow ruin and the position was shown. At 18:22 the life was saved by firemen rescue team successfully.
