AI Technical Summary

Problems solved by technology

This technical solution only collects information from the trapped people, but the corresponding information cannot be obtained for personal self-rescue, and the subjective initiative of the trapped people at the fire scene cannot be fully utilized.
At present, there is almost no research on the application of BIM+AR technology in emergency evacuation of high-rise buildings.

Abstract

The invention discloses an escaping and rescuing assisting device based on BIM and AR technologies and belongs to the technical field of rescuing equipment. The escaping and rescuing assisting devicecomprises a worn device and a data acquiring and transmitting device; a BIM model of a building is stored in a microcomputer of the worn device; a certain amount of sensor units, data transmission base stations and positioning base stations are arranged at proper positions inside the building; when urgent evacuation is required, each sensor unit is used for acquiring real-time data inside the building; by amplification and analogue / digital conversion, the data is transmitted to a second communication module and the data transmission base stations; the position and speed of an escaping person are monitored in real time by the positioning base stations and positioning modules; all escaping people can share the data in real time or acquire the data from the data transmission base stations, and the data is displayed on AR glasses in real time by virtue of an augmented reality technology, so that each escaping person can find out the most suitable escaping route.

Description

technical field [0001] The invention belongs to the technical field of rescue equipment, and in particular relates to an escape and rescue auxiliary device based on BIM and AR technologies. Background technique [0002] In the current field of construction engineering, the research on BIM (commonly understood as Building Information Modeling) technology is still in its infancy. This technology establishes a virtual three-dimensional model of construction engineering and uses digital technology to provide a complete and consistent model for this model. construction engineering database. And AR (Augmented Reality, that is, augmented reality) technology is also in its infancy. AR is all about the co-location of virtual and physical spaces, or importing virtual data into real physical space. No matter what kind of display device is used, as long as Through it, it is possible to accurately co-locate data in the physical space, which involves position tracking, positioning tracki...
