Relative positioning-based danger-trapped fireman search method and device

Abstract

The invention provides a search method and equipment for firefighters in distress based on relative positioning, which solves the problem of target positioning in the rescue of firefighters in distress. Between any two relative positioning devices provided in the method, the height difference, relative orientation and relative distance between the devices can be measured. Every firefighter entering a fire wears a relative positioning device. The rescuers find the firefighters in distress by using the relative altitude difference, relative orientation and relative distance measured between the relative positioning equipment worn by themselves and the relative positioning equipment worn by the firefighters in distress.

Description

technical field [0001] The present invention, that is, a search method and equipment for firefighters in distress based on relative positioning, belongs to the field of fire emergency rescue. In addition, the present invention can also be used for searching and rescuing any person or object carrying a relative positioning device. Therefore, the method and system can also be applied to other occasions where people in distress are searched and rescued, including military, public security, outdoor sports, orienteering, geological disaster rescue and the like. Background technique [0002] The safety guarantee of workers in high-risk industries has the characteristics of involving a wide range of industries (including: fire protection, coal mines, petrochemicals, etc.), a large number of personnel, and high risks. It is a difficult task. Once a vicious event occurs, it will bring huge loss of life and property, and cause certain social impact. Therefore, the development of saf...

Problems solved by technology

However, the real-time positioning and tracking solution is too poor in practicability, and there are two fatal flaws when applied to personnel search and rescue: (1) Accurate on-site maps are required

At present, a large number of architectural structural drawings in China are only archived in paper version, and it is almost impossible to obtain an accurate map of the fire scene in real time

(2) Rescuers cannot know the location of the trapped firefighters and cannot actively search

Therefore, after years of research and development, although small-scale experimental systems are common, there are still no emergency personnel positioning products that can be applied to actual combat on a large scale worldwide.

[0004] To sum up, the existing search and rescue technologies for firefighters in distress are difficult to meet the needs of emergency rescue scenarios in complex environments, and their practical application capabilities are poor.

There is an urgent need for practical application needs to innovatively develop a rapid search and rescue technology and equipment based on an in-depth analysis of the essential needs and technical challenges of the search and rescue of firefighters in distress, so as to realize "reasonable and evidence-based" search and rescue, and solve the current problem that can only be solved by "blind search".
