Description

technical field

[0001] The invention relates to an underground personnel positioning search and rescue system. The invention specifically relates to technical fields such as WI-FI wireless communication and wireless positioning. Background technique

[0002] Downhole personnel positioning is an important measure for safe production. Over the years, people have used various methods to detect the location of underground personnel. When an accident occurs in a mine, the positioning system can provide an important reference for personnel search and rescue. But the current positioning and search and rescue system has the following deficiencies.

[0003] At present, the actual use is mainly based on radio frequency identification technology (RFID). RFID uses radio frequency to carry out non-contact two-way communication to achieve the purpose of identification and exchange data. Different from other contact identification technologies, the RFID system can realize automatic iden...
