The Life Detector can detect movements in real time. It can penetrate concrete, brick, snow, ice and mud and is dedicated to large-scale natural disasters such as earthquake disasters, snow disasters and mudslides. The life detector mobile detection system is a sensor composed of the following main components. It includes a transmitter for transmitting an ultra-wideband signal, a receiver for detecting a reception return signal, and a signal for reading in a receiver and performing The algorithm handles the computer and the sensor contains programmable firmware. The signal generated by the sensor is transmitted to the handheld computer (PDA controller) for display via wireless transmission. Sensors and controllers have their own independent power supply.
The life detector is simply a breathing and motion detector. Its working principle is that the radar signal transmitter continuously emits an electromagnetic signal and scans a certain space. The receiver continuously receives the reflected signal and performs algorithm processing on the return signal. If the detected person remains stationary, the return signal is the same. If the target is moving, the signal will be different. By comparing the signals received in different time periods and other algorithm processing, it can be determined whether the target is moving. The life detector works by testing the subject's breathing movement or movement. Because of the low frequency of breathing, which is usually 1 or 2 times per second, breathing exercises can be distinguished from other higher frequency sports. Compared to other lifesaving systems, most systems, such as camera systems, have very limited scope for detection, except that they cannot penetrate obstacles to detect movement. They can only be alerted when a moving person in danger enters the field of view of the camera lens or sensor. Audio-based detection systems are greatly limited by distance, obstacles, wreckage, and whether the person in danger is still strong and awake to be able to make sounds.
