A vital sign simulation device and simulation method for rescue training

Abstract

The invention discloses a vital sign simulation device for rescue training and a simulation method. The vital sign simulation device comprises a shell and a radar cross section simulation sheet for simulating corresponding radar cross section sizes during the human body target detection of a radar, wherein the radar cross section simulation sheet is fixed in the shell, and the radar cross sectionsimulation sheet swings according to specified amplitude and frequency so as to simulate the vital sign state of a human body. According to the simulation method, the area, swing amplitude and swing frequency of the radar cross section simulation sheet during the simulation of different human body targets are determined in advance; and during rescue training, the vital sign simulation device is arranged at a designated position; the radar cross section simulation sheet is made to swing according to target amplitude and frequency. The vital sign simulation device for rescue training of the invention has the advantages of simple and compact structure, low cost, small weight and small size, and can be applied to the rescue training of radar life detector devices so as to realize vital sign simulation. The vital sign simulation device has the advantages of high simulation precision and the like.

Description

technical field [0001] The invention relates to the technical field of rescue training, in particular to a vital sign simulation device and simulation method for rescue training. Background technique [0002] After earthquakes, landslides, mudslides and other disasters, how to quickly search, locate and rescue survivors is an urgent problem that needs to be solved. At present, all localities have also comprehensively strengthened the allocation of search and rescue equipment and rescue training. In the rescue and search process, radar life detectors are usually used at present. Radar life detectors are a kind of vital sign target search equipment that combines radar technology and biomedical engineering technology, and can penetrate non-metallic media (brick walls, ruins, etc.) Non-contact, long-distance detection of human vital signs (such as breathing, heartbeat, body movement, etc.), and the radar life detector has no constraints on the measured object, and can penetrate ...

AI Technical Summary

Problems solved by technology

[0003] At present, for rescue training, real people are usually directly used as trapped persons, which has many disadvantages such as low efficiency, simple scene, single training and poor safety.

Although radar life detector equipment manufacturers have product factory inspection equipment, the equipment is usually large in size, inconvenient to use for search and rescue training, single type of signal source (usually mechanical), poor versatility, and low environmental tolerance and unreliable lifespan, which cannot meet the needs of rescue simulation training

[0004] There are some devices capable of simulating vital signs in the prior art, but they are usually used in the medical field, that is, to provide simulated signals for various types of medical rescue equipment. Signals are required, and the medical vital sign simulation equipment is usually large in size, not suitable for hiding under the ruins, nor can it simulate the changes of different age groups, genders and vital signs over time, which cannot meet the simulation training needs of rescue teams
