Radar life detector working principle, brand and maintenance

Radar life detector is a life detection device integrating radar technology and biomedical engineering technology. It is mainly made by using the principle of reflection of electromagnetic waves. By detecting various micro-motions caused by human life activities, information on breathing and heartbeat can be obtained from these micro-motions, thereby identifying whether there is life.

With current technology, the radar life detector is the most advanced life detector. Its active detection method makes it less susceptible to factors such as temperature, humidity, noise, and site topography. The continuous emission mechanism of electromagnetic signals increases its Regional detection function.

First, the United States Radover radar detector

Radford Radar Life Detector adopts ultra-broadband wireless transmission technology and is the most advanced radar life detector at present. It has performed well in disaster sites such as earthquakes, building collapses, mudslides and avalanches. The main advantages are as follows:

1. It is not necessary to attach any electric cables or long rods to search and locate trapped persons under the rubble. The use of the latest advanced wireless transmission technology, with fast moving, light equipment , simple operation, anti-jamming, etc., suitable for harsh rescue environment characteristics.

2, can be detected within 30 seconds within the range of movement of persons in distress and breath, can penetrate obstacles (e.g. snow reinforced concrete brick, asphalt layer, caused by landslides and avalanches) for detecting, from the sound And the influence of background noise.

3 , slight shallow breathing test motion, within 30 seconds in search of rescue dogs can not reach the place can also accurately search for signs of life.

4 , do not need to drill, arrange the cable and carry on the mute processing to the environment, make the search and rescue job become simple and easy.

5 , can work in any environment.

Second, radar life detector maintenance

( 1 ) During the long-term storage, the radar should be checked regularly for start-up. The inspection contents are: whether the system is working properly and whether the battery power is sufficient;

( 2 ) The radar should be kept clean and clean. When cleaning, wipe gently with a clean (or mild soapy water) rag;

( 3 ) Do not use the radar in a high temperature environment for a long time, otherwise it will affect its service life.
