Embodiment 1

[0048] This embodiment provides a navigation method for rapid inspection of the mine ground, which is applied to a mobile terminal equipped with a navigation system, such as figure 1 shown, including the following steps:

[0049]S101: Obtain the underground layout drawing of the mine, and determine the drawing coordinate system adopted by the underground layout drawing; usually, the underground layout drawing is in CAD format, and the staff will pass the required drawing information through CAD in advance The software produces underground layout maps on the drawings, and the underground layout maps can be excavation work plans, roadway layout drawings, bird's-eye views with roadways, geological topographic maps and other related maps. The coordinate system adopted by the general underground layout map is the WGS84 coordinate system [the origin of the coordinates is the center of mass of the earth, and the Z-axis of the rectangular coordinate system in the geocentric space poin...

Embodiment 2

[0064] This embodiment provides a navigation device for fast inspection of mine ground, such as Figure 4 shown, including:

[0065] Drawing acquisition unit 301, obtains the underground layout drawing of the mine, and determines the drawing coordinate system that described underground layout drawing adopts; Usually, the described underground layout drawing is in CAD format, and the staff pre-orders the required drawing The underground layout map can be obtained on the drawing through CAD software, and the underground layout map can be excavation work plan, roadway layout map, bird's-eye view with roadway, geological topographic map and other related maps. The coordinate system adopted by the general underground layout map is the WGS84 coordinate system [the origin of the coordinates is the center of mass of the earth, and the Z-axis of the rectangular coordinate system in the geocentric space points to the direction of the protocol earth pole (CTP) defined by BIH (Internation...

Abstract

The invention provides a navigation method and system for rapid routing inspection on mine ground. The method comprises carrying out coordinate and format conversion on mine underground layout graphs (such as a mining engineering plane graph and a mine surface-underground contrast graph) so that requirements of a coordinate system and a base graph format of a navigation system in the mobile terminal are satisfied, and displaying the processed underground layout graphs as navigation interfaces in the navigation system so that the navigation interfaces contain the underground contrast graph. The mobile terminal can automatically acquire the current position coordinates of the mobile terminal in real time when the navigation system is started so that the current position coordinates of the mobile terminal can be displayed in the navigation interfaces of the underground layout. Through the method and system, the underground layout graphs fit to the navigation system in the mobile terminal so that staff positions can be fast found in the navigation map loading the underground layout and the method and system can assist the staff to complete missing ground information on the mining engineering plane graph.

Description

technical field [0001] The invention relates to the technical field of inspection of ground objects in mining areas and site selection of various engineering grounds, and in particular relates to a navigation method and system for quick inspection of mine grounds. Background technique [0002] At present, the working method and process of mine ground investigation (including ground survey, delineation of ground subsidence area, site selection of ground projects related to underground supporting facilities, site selection of exploration drilling, and sketch of exposed strata) are all carried out by the ground feature commissioner in the office first. Determine the location of the target area based on relevant maps (such as excavation engineering plan, surface contour map, roadway layout, etc.), record the coordinates of the target area, and then lead the relevant personnel to the ground to find the location of the target area using GPS. All handheld GPS on the market use Nati...
