Problems solved by technology

[0003] At present, there are few innovations in domestic products suitable for tunnel emergency rescue equipment, and the widely used products mainly include audio and video search and rescue instruments, infrared search and rescue instruments, etc., their performance and application conditions are subject to many restrictions, and they cannot be effective under harsh conditions. Realize the detection of life information of trapped persons

Embodiment Construction

[0035] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0036] The core technology of the present invention is the microseismic monitoring principle. When the rescuer hits the rock or structure, it will cause the composite vibration of the structure in pulse type and overall wave type, and the energy will spread around in the form of elastic wave, and the expression in the structure is shock wave (including P wave, S wave and surface waves, etc.), the form of expression in the air is sound waves. The elastic wave propagates through the medium of the surrounding rock mass, is sensed by the pre-arranged shock pickup sensors on the periphery of the landslide, and is received, recorded, interpreted and displayed by the host device, and finally realizes the detection of the life information of the trapped persons....

Abstract

The invention discloses a method for detecting life information and belongs to the field of post-disaster life information detection, search and rescue. The method comprises following steps: step 1: multiple geophone sensors are used for collecting signals which are knocking signals sent by trapped people in an area to be searched and rescued; step 2: a STA / LTA algorithm is used for recognizing collected signals to obtain pulse frequency and time interval of the knocking signals; step 3: the recognized signals are interpreted according to a pre-determined knocking rule constituted by pulse frequency and time interval to obtain distress information corresponding to the knocking signals; and step 4: the distress information is displayed on a display screen. By use of the method, life status of trapped people is determined through picking up knocking signals of the trapped people, distress information of the trapped people is determined through signal interpretation, and the life information detection of trapped people can be effectively realized.

Description

technical field [0001] The invention relates to the field of post-disaster life information detection and search and rescue, in particular to a life information detection method. Background technique [0002] In recent years, my country's expressway, urban rail, resource development and other projects related to underground excavation have developed rapidly. Along with the expansion of highway mileage, disasters and accidents in tunnels under construction have also occurred frequently and become more and more serious. When a disaster occurs in a tunnel, it is urgent to know the status information of the trapped persons within the "golden 72 hours" of rescue. Tunnel catastrophes often occur in the initial lining section and the excavation working face. The collapse of the initial lining section cuts off the tunnel, and the construction workers in front of the working face are trapped and unable to communicate with the outside world. The catastrophe of the excavation working f...
