Abstract

The invention discloses a location system and method for underground mine workers. The method comprises the steps of receiving position information sent by signal emission units carried by underground mine workers; converting the position information into power line carrier communication signals and transmitting the position information to underground mine power cables; receiving the power line carrier communication signals from the power cables and determining positions of the underground mine workers according to the power line carrier communication signals. By means of the location system and method, costs required for underground mine worker location are reduced, and the prior equipment universality is improved.

Description

technical field [0001] The invention relates to the technical field of underground operations, in particular to a mine underground personnel positioning system and method. Background technique [0002] With the improvement of the automation degree of the mine system, the safety of the underground personnel in the mine has been guaranteed to a certain extent. Now it can basically realize the accurate positioning of underground personnel, danger alarm and other functions. [0003] Among the existing underground personnel positioning technologies, some use wireless network transmission to transmit personnel positioning data; some use wired network to transmit personnel positioning data. No matter which method is used, it is necessary for personnel to locate the receiving and transmitting device of signal data, which results in an independent signal transmission system. In this independent system, it is necessary to re-lay a separate transmission channel, that is, the communic...
