Positioning navigation system for underground channel

Abstract

The invention discloses a positioning navigation system for an underground channel. The system comprises: a communication network connecting module used for accessing the system into a communication network; a map input module used for inputting a map of the region of the underground channel; a map extraction module used for extracting the map of the region of the underground channel; a data processing module used for decomposing the extracted region map to obtain a map containing all channel outlets; a touch screen display module used for displaying the extracted region map and the map containing all the channel outlets and inputting a positioning destination; and a GPS positioning module used for establishing connection with a GPS satellite and positioning according to the input positioning destination to obtain a navigation route and all channel outlets on the route, wherein the data processing module maps the received navigation route to the map containing all the channel outlets and displays all the channel outlets and the navigation route. The system realizes the positioning navigation function of the underground channel, realizes rapid arrival to the destination, and saves the time of traversing of the channel.

Description

technical field [0001] The invention relates to a positioning and navigation system for underground passages, belonging to the technical field of wireless positioning. Background technique [0002] In urban roads, underground passages are common dredging passages. Especially in the traffic system with relatively congested and complicated traffic, it often runs through some non-surface-shaped traffic network roads, mostly referring to underground sidewalks. A large number of pedestrians can pass through quickly and safely, which solves the pedestrian traffic congestion and safety problems in large cities, and at the same time plays a role in beautifying the city's landscape. [0003] Traditional underground passages are composed of roads and multiple passage intersections. Usually, different passage intersections are located in different positions and directions, so that people who enter the passage can go to various places, thus realizing the function of the passage, which ...
