Fire evacuation system and method based on indoor positioning

Abstract

The invention provides a fire evacuation system and method based on indoor positioning, and belongs to the technical field of geographic information. The system comprises a mobile terminal, a server and multiple Beacon base stations, wherein connection between the mobile terminal and the server is established, so that the fire-fighting facility information, the fire behaviour and the indoor map ina building are obtained; wireless communication connection between the mobile terminal and the Beacon base station is established through low-power Bluetooth; the real-time position of the mobile terminal is calculated by utilization of a trilateral positioning algorithm; and furthermore, the position information is uploaded to the server. The system performs indoor positioning by using the Beacon equipment; the Beacon base stations are pre-arranged indoors and powered by a battery; and continuous positioning in a possible outage condition can be carried out when a fire happens.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a fire evacuation system and method based on indoor positioning. Background technique [0002] With the rapid development of urbanization, buildings are gradually becoming large-scale, high-rise and complex. High-rise and large-scale modern buildings have the following characteristics: the internal structure space is relatively complex, the functions provided are various, the personnel are relatively dense, and the indoor personnel are not familiar with the overall structure of the building, and the evacuation efficiency in case of fire not tall. Therefore, how to improve the evacuation efficiency of indoor personnel when a fire occurs, so that personnel can evacuate from the building safely and quickly is an important issue. [0003] The current disaster prevention of large buildings mainly has the following development directions: 1) Through regular fire dril...

AI Technical Summary

Problems solved by technology

The system also cannot be updated in real time according to the on-site situation. At the same time, due to the chaos and the complexity of the building when a fire occurs, personnel may miss the sign, thus affecting the efficiency of evacuation

At the same time, when firefighters rescue trapped people, it is difficult to determine the specific location of the trapped people, which affects the efficiency of rescue.
