Dkl lifeguard life detector (pictured)
Dkl lifeguard life detector is the most advanced search and rescue instrument in the world at present, and its light volume is only about 1kg. It is designed by hand, easy to carry and operate, and its performance is superior to any other high-tech search and rescue products. It has been widely used by the military, customs, sea patrol, fire protection, security, rescue, aerospace and other government departments in advanced countries in the world.
This product was developed by American high-tech companies combined with the world's most advanced biochemical, dielectric, ultra-low frequency conduction and DNA technologies, and applied for a number of technical patents. This model is the most mature product designed by DKL company at present.
Lifeguard life detector provides rescuers with the ability to confirm whether there are survivors when they enter the search and rescue site, so as to reduce the danger of rescuers in search and rescue and detect survivors behind any obstacles at the first time. It detects the direction of the distant weak heartbeat dielectric field through passive reception, and only detects the surviving humans without interference from other animals. It can cross various obstacles such as steel plates, cement, composite materials and trees, so that the detection distance can reach 500 meters in the open area.
After special treatment, it is suitable for all kinds of bad weather conditions, with simple maintenance and extremely low failure rate. If it is combined with portable computer and special artificial intelligence software, it can generate detected image and sound information, further improve the discrimination ability of operators and reduce the training time of novices.
Life buoy life detector application scope:
Coastal defense: search for places where illegal stowaways may hide, such as sea, coast, mountains, ports, empty houses, cabins, containers, etc.
Rescue: Search for survival targets such as rivers, lakes, mountains, earthquake landslides, mine explosions, fire scenes, etc., and confirm whether there are survivors. It can also be used to track the life safety of search and rescue personnel.
Searching and tracking police/security/military dangerous areas and various complex obstacle areas can find targets early and reduce casualties.
Used together with other life search instruments, such as rescue dogs, sound/image detectors, infrared/thermal imaging detectors, etc. The overall search and rescue effect has been greatly improved.
Basic overview
Life detector is a kind of safety life-saving system newly launched by American over Safety System Company in 2005. David Cist, a famous physicist and Ph.D. of Massachusetts Institute of Technology, creatively applied UWB technology to the field of safety and lifesaving, thus bringing a revolutionary new technology to this field. The Life detector lifesaving system based on this new technology has successfully solved many problems that plague the traditional lifesaving system, making the search and rescue work faster, more accurate and safer than before. This is the most advanced life detection system in the world. The antenna of the system is one of the two candidate radar antennas for Mars probe designated by NASA, and it is the most advanced ground penetrating radar antenna in the world, which can capture very weak motion very sensitively. This product has been patented in the United States. Regulatory Security Systems recently launched this system in China, the United States and Japan.
Instrument composition
The mobile detection system of the life detector of the supervision safety system company is a sensor consisting of the following main components:
A transmitter for transmitting ultra-wideband signals
A receiver for detecting the received return signal
A computer for reading signals from a receiver and performing algorithmic processing.
The sensor contains programmable firmware. The signal generated by the sensor is transmitted to the PDA controller for display through wireless transmission. Sensors and controllers have their own independent power supply.
principle of operation
The life detector is actually a breathing and motion detector. The radar signal transmitter continuously emits electromagnetic signals and scans a certain space, and the receiver continuously receives the reflected signals and performs algorithm processing on the returned signals. If the detected person remains still, the return signal is the same. If the target is moving, the signal is different. By comparing the signals received in different time periods with other algorithms, we can judge whether the target is moving.
The working principle of life detector is to detect the breathing movement or action of the detected person. Because of the low frequency of breathing, which is generally 1 2 times per second, breathing movement can be distinguished from other higher frequency movements. The principle of measuring motion is basically the same. The antenna of Supervisory Safety System Company is one of the two kinds of ground penetrating radar antennas of Mars probe designated by NASA, which can capture very weak motion very sensitively, and with powerful algorithm processing, it is the best helper for safety and life-saving departments.
technical superiority
The life detector that supervises the safety system aims to solve the fundamental shortcomings of the existing life-saving systems in the market. At present, life-saving systems can't detect movement through obstacles, but most systems, such as camera systems, have very limited detection range and can only give an alarm when people in distress enter the field of vision of camera lens or sensor. Audio-based detection system is greatly limited by distance, obstacles, debris and whether the person in distress is still strong and awake enough to make a sound.
Survision Security Systems' life detector can detect the movement and breathing of people in distress in a certain range within 30 seconds, and can penetrate obstacles (such as reinforced concrete brick walls, asphalt layers, snow caused by mudslides and avalanches) for detection, which is not affected by sound and background noise. The sensor of the supervision safety system company can send out the signal containing the target designation information, thus making the detection activities faster and more accurate, and making the first responders, security personnel and military personnel involved in the rescue safer.
General characteristics
The basic characteristics of life detector include: real-time moving detection, which can penetrate concrete, bricks, snow, ice and mud;
Detecting movement and detecting the distance of people in distress;
Able to work in all kinds of weather conditions;
Intuitive and easy to learn, without a lot of special training;
Low requirements for power supply energy;
Almost no system maintenance is needed;
Firmware programs can be upgraded through wireless or wired networks;
There is no need to drill holes, lay cables and mute the environment, so the search and rescue work is simple and easy. In the race against time rescue work, life detectors can help search and rescue personnel find survivors in distress quickly, accurately and safely, thus winning valuable time for rescue work.
