Abstract

The invention discloses a search-and-rescue positioning system for an underground mine disaster. The search-and-rescue positioning system for the underground mine disaster comprises a wired signal transmission network distributed underground, multiple position finders which are distributed underground and are connected with the wired signal transmission network, a transmitter installed on a movable device, a control center arranged on the ground and a signal receiving terminal used for search and rescue, wherein the control center is connected with the wired signal transmission network and receives positioning signals transmitted by the position finders, the transmitter is worn by an underground operator and moves along with the underground operator, and the signal receiving terminal is carried with a search and rescue person, moves along with the search and rescue person to be close to the underground operator trapped underground and gives a wireless signal response to the transmitter carried with the underground operator. The search-and-rescue positioning system for the underground mine disaster is simple in structure, low in establishment cost and high in positioning speed and positioning precision, and the advancing direction of the underground operator can be confirmed; the position of the trapped person can be found out rapidly when the mine disaster occurs so that rescue can be conducted in time.

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 an underground mine disaster search and ...
