Abstract

The invention provides an individual fireman positioning and navigation device. The device comprises a satellite navigation information receiving module, an electronic compass module, a barometer module, an electronic map module, a storage module, an MEMS inertial navigation module, an image information code reading module and a central processing unit module; first positioning information is obtained through the satellite navigation information receiving module; second positioning information is obtained through the electronic compass module; third positioning information is obtained through the barometer module; the electronic map module displays a map and makes comprehensive positioning information transmitted by the central processing unit module be displayed on the map; fourth positioning information is obtained through the MEMS inertial navigation module, the image information code reading module reads preset image information codes to obtain control information; the central processing unit module performs data fusion on the received control information, the first positioning information, the second positioning information, the third positioning information and the fourth positioning information to obtain the comprehensive positioning information. The individual fireman positioning and navigation device is widely applied to the field of fire protection and disaster relief.

Description

technical field [0001] The invention relates to an indoor positioning and navigation device, in particular to a positioning and navigation device used by firefighters entering an indoor fire place. Background technique [0002] Fire poses a huge threat to human life and property safety, especially in cities, where rescue work after high-rise buildings catch fire is very difficult. When firefighters enter the fire scene, it is difficult for firefighters to know their location due to factors such as smoke interference and changes in building structure, which greatly affects the rescue. [0003] People try to use satellite positioning system (for example technologies such as GPS) to carry out the positioning and navigation of firefighters fire scene. As we all know, due to the obstruction of the wall, it is not easy to receive satellite signals indoors. Therefore, it is difficult for firefighters to know their own positions stably and reliably by using satellite positioning te...
