1. Product introduction:
The radar life detector is based on the life detection technology of the two-dimensional bio-radar, and is developed by using integrated micro-power ultra-wideband radar technology and biomedical engineering technology. The system adopts multi-transmit and multi-receive imaging array technology, which can accurately locate life bodies in the region , For rapid detection and positioning of rescue scenes, and rapid rescue at fixed points. It has the advantages of wide space-time coverage area, high measurement dimension, good performance stability and target spatial resolution, and can obtain more comprehensive and accurate life body and disaster relief site environmental information, which is for the development of efficient and feasible rescue The plan provides a basis for decision-making, shortens rescue time, reduces disaster losses, and is widely used in special industries such as fire fighting, earthquake, and emergency response.
2. Working principle:
Based on the principle of ultra-wideband impulse radar, using heartbeat signals and breathing signals as the characteristics of human life parameters, the two-dimensional coordinates of life bodies are directly obtained, so as to realize the detection of moving or stationary life bodies buried in mines or ruins, to the maximum extent The guaranteed detection and rescue effect.
The whole device is composed of a radar host and a handheld PDA; it is small in size, light in weight, no probes and cables, easy to arrange and operate, accurate in positioning, and meet the requirements of harsh rescue environments. The integrated design of the whole machine, simple operation, ultra-low power consumption, waterproof, shockproof, dustproof and cold proof, can be used in various harsh environments.
3. Functional indicators:
1. Non-contact detection: breathing detection and motion detection of living bodies. The detector can detect characteristic signals such as breathing or heartbeat of living bodies without digging ruins, digging holes and piercing holes, and without touching living bodies.
2. Probe playback: re-display the historical scanning process.
3. File management: delete terminal target files: download, delete or view host target files.
4. The control terminal has the function of controlling the radar host, including: host initialization, start detection, parameter setting, mode selection, equipment self-check, stop and close functions.
5. Scanning and display function: The detector is equipped with hierarchical scanning and searching of the area, with a two-dimensional positioning function, which can obtain the two-dimensional coordinates of the living body and display it on the display control terminal.
6. Detection time selection function: The display control terminal has a detection time selection function, which can choose to manually stop, detect 60 seconds, detect 90 seconds or detect 120 seconds.
7. With intelligent discrimination function: through intelligent algorithms, it can automatically judge whether there is a living body, distinguish moving targets and stationary targets, and have the function of trajectory display/hide selection. The detected human motion and stationary targets (respiration results) are displayed on the screen with different color graphics. The green icon with a motion track represents a moving target, and the red human icon represents a stationary target.
8. Data transmission function: with wireless data transmission function.
9. Power display function: the handheld PAD can display the power of the machine, and also display the battery power of the radar host. When the battery power is low, there should be an alarm and prompt on the display and control terminal screen.
4. Performance indicators:
1. The main radar is an ultra-wide pulse radar with a center frequency of 400MHZ.
2. The whole machine is composed of a radar host, a handheld computer (PAD), a three-proof packaging box (waterproof, dustproof, shockproof and anti-fall) and other accessories.
3. Detection distance of partition wall: penetration 60cm wall (ruin, brick wall), detection distance of stationary life body ≥28m; detection distance of moving life body ≥37m;
4. Detection and display: moving targets and breathing targets are displayed in different color graphics. The moving target has a moving track and real-time tracking display; the green icon with the moving track represents the moving target, and the red human-shaped icon represents the stationary target.
