Abstract

The invention discloses a point-to-point positioning system for a downhole mine tunnel. The point-to-point positioning system comprises a plurality of position indicators, transmitters installed on movable devices, and a control center arranged on the ground, wherein the position indicators are distributed in the downhole mine tunnel in a fixedly-arranged mode and are connected with the control center in a wired mode, the transmitters are worn by downhole operating personnel and carry out wireless point-to-point communication with the position indicators, so that the position indicators obtain information of angles and distances between the transmitters and the position indicators, the control center processes the information of the angles and the distances after receiving the information, sent by the position indicators, of the angles and the distances, and the transmitters are positioned. The point-to-point positioning system for the downhole mine tunnel is simple in structure and low in creation cost; a technology of wireless point-to-point positioning between the transmitters and the position indicators has high positioning accuracy, and the advancing direction of the downhole operating personnel can be determined.

Description

technical field [0001] The invention belongs to the technical field of point-to-point positioning communication, and in particular relates to the positioning technology in underground mine tunnels. Background technique [0002] Underground mine operation is a very dangerous job. In order to ensure the safety of operators in the event of mining accidents, a dynamic distribution and positioning monitoring system for operating personnel is usually built underground, so that personnel can be notified to evacuate as soon as a mine accident occurs. And dispatch the downhole equipment. However, the current underground positioning system is complex, the construction cost is high, and the communication transmission is limited due to the complex underground terrain. Contents of the invention [0003] Purpose of the invention: In view of the above-mentioned existing problems and deficiencies, the purpose of the present invention is to provide a point-to-point positioning system for ...
