Abstract

The invention provides a navigation system for entering a deep well tunnel, which includes an electronic compass, a controller and a direction indicator. The network map of the deep well tunnel is stored in the controller. At least one of the ports communicates with corresponding ports of multiple tunnels, and each tunnel is divided into at least one road section, each road section is straight or only bends in one direction; after the controller receives the destination road section selection signal, According to the real-time orientation information detected by the electronic compass and the first orientation information and the second orientation information of each road section, determine whether the user goes to the first port of the corresponding tunnel, if so, control the direction indicator to indicate the direction, so that the user Choose to enter the correct tunnel, where the first port refers to the port that is farther away from the entrance and exit of the deep well tunnel among the two ports of the corresponding tunnel. The invention is not limited by communication distance, and can realize accurate navigation of deep wells.

Description

technical field [0001] The invention belongs to the field of coal mine operations, and in particular relates to a deep tunnel entry navigation system. Background technique [0002] According to production needs, intricate tunnels may appear in deep coal mines. When mining personnel go from the tunnel trunk to the tunnel branch they are working on, they may not be able to reach the expected tunnel branch due to complicated routes. Since deep coal mine shafts are usually deep, when using GPS (Global Positioning System, Global Positioning System) positioning and other methods for navigation, the signal in the deep shaft is very weak, and accurate navigation cannot be achieved, and sometimes even signals cannot be received. For this reason, corresponding signs are generally provided in deep shaft tunnels to indicate the directions of the corresponding tunnel trunks and branches. When setting up signs, it is necessary to ensure the accuracy of the signs, and it takes a certain a...
