Firefighter positioning and vital sign monitoring method in complex emergency rescue environment

Abstract

The invention discloses a firefighter positioning device in a complex emergency rescue environment. The device comprises a front-end wearable non-inductive terminal device and a backfield command system. The front-end wearable non-inductive terminal device comprises a firefighter dual-mode safety positioning module, a vital sign detection module, a dual-mode wireless communication module and the like. The backfield command system has the functions of data tabulation display, gridding building model and firefighter real-time position visual display. The wearable non-inductive terminal device adopts a wireless communication mode that a Lora module and an NB-IOT module work at the same time or work is switched. The wearable non-inductive terminal device can collect vital sign data of the firefighter in real time and submit the data to the background system for analysis and processing. Real-time acquisition of the position of a firefighter, real-time acquisition of firefighter body safetyinformation data and real-time issuing of a fire-fighting instruction are realized in a high-temperature dense smoke environment of a fire scene, the life safety of the firefighter during fire fighting is guaranteed, and the fire rescue efficiency is improved.

Description

technical field [0001] The invention relates to the fields of sensor application, computer application and communication technology, in particular to a personnel positioning, life safety monitoring and communication device applied in complex environments such as emergency rescue. Background technique [0002] The patent number is CN201110047495, the application date is 2011.02.28, and the name is "firefighter's on-site navigation device". The on-site navigation device for firefighters includes: a central control module, a three-dimensional positioning module, an external storage module, a communication module, an input and output module and several core modules of the protective shell. Through the cooperative work of these core modules, it is determined that the firefighters The three-dimensional location of the scene, and inform the firefighters with a clear and intuitive voice or image mode, and at the same time indicate the location of various firefighting facilities to t...

AI Technical Summary

Problems solved by technology

[0010] The technical problem to be solved by the present invention is that in the complex environment of emergency rescue, the commanders and fighters in the back field cannot timely know the real-time position of the firefighters in the fire field and the attitude of the firefighters, and limited by traditional communication, in complex emergency rescue In the environment, it is easy for the signal to be disconnected from time to time, or completely disconnected, which leads to the problem that the commander cannot issue orders in time
