Intrinsically 50s Life Detector Multi Target Detection Capability

Life Detector / Earthquake Rescue Equipment/ YSR25 intrinsically safe radar life detector

Introduction

YSR25 intrinsically safe radar life detector is a microwave life detection equipment for free space and penetrate non-metallic media life detection, mainly used to be buried in collapsed buildings, the rubble, the soil of human survivors or smoke, fog and other environments detect human life body search. Small size, light weight, simple structure, good man-machine interface, easy operation, strong anti-jamming capability, environmental adaptability and other characteristics.

Principle

YSR25 EX-proof radar life detector is a mine rescue advanced life detector. Its penetration ability, can detect buried miners breathing, body movement and other vital signs, and can accurately measure the depth of the buried life from the body, with a strong anti-interference ability, from the ambient temperature, hot objects and sound the impact of interference, has broad application prospects.

YSR25 EX-proof radar life detector has great relative bandwidth (bandwidth and center frequency ratio of the signal), generally greater than 25%, the test parameters of human life is a form of pulses of microwave beam body, due to the activities of human lifeIt exists (breathing, heartbeat, peristalsis, etc.), so that the cycle is repeated after the body reflectance echo pulse sequence changes. If echo pulse sequence reflected by the human body demodulates, integration, amplification, filtering, processing, and entered into the computer for data processing and analysis, we can get the parameters and measured characteristics related to human life.

Main performance and technical parameters

① detection range: an opening angle of the cone region of 120 °, the maximum detection distance of more than 25m, depending on the detection distance field environment will be a certain degree of influence;
② target response time: <50s;
③ penetration: penetrate non-metallic obstacle be detected. Reference data: load-bearing masonry structure after two human respiratory signal 5m or three brick structure after the body motion signal 5m of load-bearing walls;
④ wireless communications capabilities: radar detectors and unobstructed between the display controller, wireless communication distance of more than 50m;
⑤ range accuracy: ≤ ± 0.5m (without shelter in the state);
⑥ Operating temperature: radar detector -10 ℃ ~ + 50 ℃;
The display controller -30 ℃ ~ + 60 ℃;
⑦ continuous working time: ≥5h.

Applications

YSR25 ex-proof radar life detector for detecting underground explosive atmospheres life have penetration, the role of distance accurately, anti-interference ability, strong multi-target detection capability to detect high sensitivity, detection range up to 25 m.
