Description

technical field

[0001] The invention relates to a rescue system, in particular to an underground personnel positioning rescue system and an underground personnel positioning method. Background technique

[0002] The existing underground personnel positioning system is mainly a communication system between ground personnel and underground personnel. In the 1820s, the potential for wireless communication with miners trapped underground was realized through experiments with underground reception of long waves. However, it was impossible to design a practical wireless communication system with the technical level at that time. Since then, further research using electromagnetic waves downhole has mainly turned to geophysical detection. In the 1840s, T.L. Wadley conducted the first basic research on electromagnetic waves penetrating rock formations (Trough The Earth, abbreviated as TTE), which set off an upsurge in the study of underground electromagnetic wave propagation in Sou...
