Functional characteristics of a multifunctional life detector

All living beings exhibit vital signs; their bodies have temperature, respiration, and heartbeat, all of which produce carbon dioxide. These are multifunctional the basis for life detectors to collect and judge survivors. But how is this human information reflected in the detector?

　　Respiration is one of the vital signs of a human being. Exhaled carbon dioxide is one of the means to explore whether there are survivors in a collapsed area after a disaster. If the detection conditions are good, sound search will be very efficient, but if the survivor has lost consciousness but is still breathing, then multifunctional a life detector can play a role. Especially in enclosed spaces, the slightly higher concentration of carbon dioxide will be beneficial to the detector's work. Because living people and animals will exhale carbon dioxide, it is difficult to distinguish whether the survivor is a human or an animal from this detection result. Therefore, when using a carbon dioxide detector, it needs to be used with other types of detectors; its use alone is not high.

Micro-vibration multifunctional life detector is a security device used in prisons, customs, border control, and other places. Today, micro-vibration multifunctional life detector has been widely used, but people who have not come into contact with it certainly won't know. Let's talk in detail about micro-vibration multifunctional life detector the entire detection process.

　　Before using micro-vibration multifunctional life detector Before using micro-vibration, the equipment door needs to be opened, and the micro-vibration multifunctional life detector power cord and sensors (generally 5 sensors) need to be taken out. First, place the sensors on the beams of the vehicle being tested. In large vehicles, place 3-4 sensors, with the sensors attached to both ends of the beams under the vehicle, paying attention to keeping the arrows on the sensors pointing upwards. Place 2-3 sensors in small and medium-sized vehicles. For small cars (sedans), the sensors can be placed on the top of the car, while the ground sensors are placed on the ground.

　　After preparation, connect the power supply and rotate the equipment knob. The system will enter the drive state. After waiting for about one minute, the system will automatically enter the software operation interface. Click the "Start" button on the software interface to start the detection. After the system starts the detection once, it will automatically complete the detection without manual intervention. After the detection is completed, the software will display the final judgment result, and then release, search, or re-detect. It should be noted that the front and body of a large vehicle are not the same beam, so the front and body need to be tested separately. After the test, if the software analysis shows that it has passed, it can be released. The software analysis is a re-check, and you can re-check to see if there is any interference from the surrounding environment. When the software analysis shows that it needs to be searched, it is necessary to manually carefully check whether there are any suspects hiding in the vehicle. This completes the micro-vibration multifunctional life detector detection process, but the following items need to be paid attention to during the detection process, which has a great impact on the detection results.

　　1. Environmental interference. Micro-vibration multifunctional life detector uses vibration frequency to complete the detection. If there is solid ground and buildings around the equipment during construction, or if heavy vehicles are driving around the equipment, it will produce a lot of noise, interfering with the normal frequency, leading to inaccurate micro-vibration multifunctional life detector detection.

　　2. If the vehicle being tested does not have a parking brake or similar device, and the door of the vehicle being tested is not closed (shaking), hydraulic equipment should be equipped! The vehicle cannot be detected without stopping, which not only prevents normal detection from being completed but also causes safety hazards.
