Embodiment

[0017] Such as figure 1 Shown, technical scheme of the present invention comprises the steps:

[0018] Step 1. Draw the underground map in the smart device. The drawn underground map is 2D graphics or 3D graphics. The 2D map is converted into a two-dimensional array, and the 3D map is converted into a three-dimensional array; the map is divided into grids, and each local area will be There is a fixed numerical representation, and the deployed wifi base stations are drawn to the corresponding positions on the map. Each base station has a unique SSID.

[0019] Step 2, establish wifi in the underground space; the wireless signal takes the wifi base station as the center point, and radiates to the surroundings in a spherical shape; the principle of establishing wifi in the underground space is that the intersection of mutual signal coverage is small, and the signal strength is collected. Through underground measurement, the The value of the signal strength is entered into the va...

Abstract

The invention relates to a method for employing intelligent equipment for positioning under a coal mine, and the method comprises the steps: predefining a map in android equipment and setting a wifi base station point; capturing one or more wifi base stations in a mode of searching a wifi signal, setting independent SSIDs for all wifi base stations under the coal mine, wherein each SSID can determine a place, and a wireless signal takes the wifi base station as the circle center and is irradiated to the surroundings in a spherical manner. When the intelligent equipment is located in a radiation range, the SSID and the signal intensity can be obtained even if the authentication connection is not carried out. When the intelligent equipment is covered by a plurality of wifi signals, the precise positioning can be achieved through the analysis of the SSIDs and the signal intensities of the base stations.

Description

technical field [0001] The invention relates to a positioning method, in particular to a positioning method using an intelligent device in a mine. Background technique [0002] It is difficult to check the location of personnel in an underground mine. Since the underground space is a relatively closed environment, it is difficult for GPS to penetrate the surface to reach the lower space. Moreover, the underground mine is a three-dimensional space, and it is difficult to determine the specific location with a flat GPS. Contents of the invention [0003] The present invention aims at the above-mentioned problems in the prior art, and provides a method for locating underground mines using intelligent equipment, which solves the problem in the prior art that it is difficult to inquire about the location of personnel in underground mines. [0004] Technical scheme of the present invention comprises the steps: [0005] Step 1. Draw an underground map in the smart device, divide...
