In the complex environment of mine rescue, time is life. Every second of delay may make the survival hope of trapped miners even slimmer. At this time, the assistance of technological equipment is needed, such as the Infrared Life Detector.
The working principle of the Infrared Life Detector is based on the infrared radiation characteristics of objects. Any object with a temperature above absolute zero will generate infrared radiation, and the human body is no exception. Moreover, the infrared radiation characteristics of the human body are significantly different from the surrounding environment. Taking advantage of this difference, the Infrared Life Detector uses an optical system to focus the received thermal radiation energy from the human body on the infrared sensor, converting it into electrical signals. After processing, an infrared thermal image is displayed on the monitor, helping rescuers determine the location of the trapped persons.
Mine rescue often faces many challenges. The environment inside the mine is complex, with possible collapsed rocks, accumulated water, toxic gases, etc. At the same time, the light is dim or even completely absent, and dust fills the air, which brings great difficulties to traditional rescue methods. However, the Infrared Life Detector is not restricted by light conditions; it can work normally even in the pitch-dark depths of the mine. Furthermore, it can penetrate a certain degree of dust and quickly locate the target by capturing the heat emitted by the bodies of trapped miners. After a gas explosion or mine collapse, the scene may be in a mess with smoke filling the air, making it difficult for rescuers to see the surrounding situation. The Infrared Life Detector can penetrate the smoke and ruins to detect the signs of life of the trapped persons.
The Infrared Life Detector has the feature of a long detection distance. Even if the trapped persons are deep underground, they may be detected. The detection depth can reach tens of meters, enabling it to search for signs of life in a relatively large range and improve rescue efficiency. In addition, the device is convenient to carry and use. It can be operated either by remote control or wire control, making it easy for rescuers to use flexibly in various complex terrains and narrow spaces.
There was a mine collapse accident where many miners were trapped underground. Rescuers quickly carried the Infrared Life Detector to launch a search and rescue operation. In the complex mine tunnels, through this device, rescuers soon found several abnormal temperature points, determined the approximate location of the trapped miners, provided an accurate direction for the subsequent rescue operations, and finally successfully rescued the trapped persons.
