Multibasic multi-module network integration indoor personnel navigation positioning system and implementation method thereof

Abstract

The present invention discloses a multibasic multi-module network integration indoor personnel navigation positioning system and an implementation method thereof. The navigation positioning system comprises a navigation positioning server terminal, a command monitoring terminal and a plurality of terminal devices, wherein the terminal devices comprise a sensing module, an information processing module, an information transmission module and a local display module, the navigation positioning server terminal comprises an information transmission module, a high performance information processing platform and an indoor map database, and the command monitoring terminal is a remote command monitoring terminal or on-site command monitoring terminal. The navigation positioning system implementation method comprises: system initialization, multi-mode indoor high-precision personnel positioning, and multibasic real-time indoor map generation and navigation. According to the present invention, with the integration of the multiple sensors at the plurality of the terminals, the indoor map is real-timely generated in the complex and unknown indoor environment, and the high-precision positioning and navigation of the indoor personnel is achieved.

Description

technical field [0001] The invention mainly relates to the field of indoor real-time map generation and navigation and positioning, in particular to a multi-base multi-module network fusion indoor personnel navigation and positioning system and its implementation method, which is mainly applicable to personnel positioning and navigation in fire rescue and emergency rescue. Background technique [0002] At present, outdoor navigation and positioning have high accuracy due to prior maps and satellite auxiliary signals, and there are many mature products, such as Google Maps, Baidu Maps and other positioning and navigation products that rely on GPS and Beidou satellite positioning signals. However, because satellite signals cannot cover indoors, and indoor maps are difficult to obtain, indoor navigation has become a difficult and hot spot in the field of navigation and positioning. Although large companies including Google and Baidu have begun to set foot in the field of indoor...

AI Technical Summary

Problems solved by technology

However, because satellite signals cannot cover indoors, and indoor maps are difficult to obtain, indoor navigation has become a difficult and hot spot in the field of navigation and positioning.

Although large companies including Google and Baidu have begun to set foot in the field of indoor navigation, the accuracy of existing indoor navigation and positioning systems is low, and some prior information is required, such as the location of Wifi hotspots or radio frequency tags. is unacceptable

[0003] In the fields of fire rescue and some emergency relief, due to the lack of prior knowledge of the accident scene, blindly entering the scene will often cause unnecessary injuries to rescuers, and even endanger their lives.
