Mining drift node repositioning method based on mechanical antenna

The invention discloses a mining drift node repositioning method based on a mechanical antenna, which comprises the following steps: acquiring node position information of an original positioning node in a mine, and additionally installing a low-frequency transmitting node and a vibration sensor on the original positioning node; after a mine collapses, a measurement network is constructed above a mine field based on an unmanned aerial vehicle loaded with a measurement base station, a low-frequency transmitting node is started and transmits a positioning signal, a low-frequency signal of the low-frequency transmitting node is received through the measurement base station, and repositioning node position information after an accident is obtained; modeling and comparing the node position information of the original positioning node with the node position change of the repositioning node position information after the accident, and sensing the mine situation change in real time. The invention provides a quicker a
