Some knowledge points about multifunctional life detectors

Vital signs information is present within the body. This information manifests on the body's external structure through various sensory methods, such as sound wave frequencies, ultrasound, radio waves, and light waves. Different frequencies of these waves naturally result in different sensations. This vital signs information is underground Multifunctional Life Detector It simply distinguishes and displays different vital signs patterns on the screen based on the detection of these different waves, thus generating a variety of Multifunctional Life Detector 。

　　 Multifunctional Life Detector It is developed by combining radar detection technology with life science research technology. Multifunctional Life Detector The device is made using the basic principle of radio wave reflection. Based on various micromovements caused by human life activities, relevant information about normal breathing and heart rate can be obtained from these micromovements, thereby identifying the presence of vital signs. Radar detection is a global life detector, and its active detection method makes it unaffected by key factors such as temperature, environmental humidity, low-frequency noise, and construction site terrain. The electromagnetic induction data signal continuous transmission system enhances its regional detection capabilities.

　　1. Place Multifunctional Life Detector the sensor box on the rubble, and then retreat to a distance of more than 6 meters but only 15 meters (the distance between the PDA and sensor transmission cannot exceed 20 meters). The wireless controller only needs 30 seconds to detect movement and normal breathing, but this longer time can improve the detection level. It can also indicate the distance between victims. After 3 minutes, the sensor can be moved to other points in the search matrix.

　　2. A single sensor only provides the distance between victims, not the specific location, also because Multifunctional Life Detector radar detection “view” widens or narrows depending on the construction site materials. For example, a victim may be 2 meters away from the wireless antenna, but the exact location below is uncertain. If the construction site material is wet sand, the victim is likely to deviate 50 degrees from the vertical position of the concrete, while if it is dry sand or concrete debris, the viewing angle may be much wider.

　　3. Because we cannot know when misfortune will strike, daily life training is particularly important. In this way, operators can understand Multifunctional Life Detector the use of the operating system. It is equally important that the operating system of the portable computer and the PDA battery must always be fully charged.

　　 Multifunctional Life Detector There are many types. Some are electric field detection types that sense the ultra-low-frequency radio waves emitted by the human heart, generating an electric field, swinging the antenna, and finally pointing to the target. There is also infrared thermal imaging. And sound waves /vibration principles, which is simply a listener, listening for any movement. Comparison More advanced is the radar type, which uses ultra-wideband pulse radar for continuous irradiation and detection of heartbeat in the echo.
