The invention further discloses a personnel scheduling communication location method based on 2.4G RFID, UWB and LoRa.

Description

technical field [0001] The invention relates to the technical field of personnel positioning, in particular to a personnel scheduling communication positioning terminal and method based on 2.4G RFID, UWB and LoRa. Background technique [0002] The underground personnel positioning system currently used in mines generally adopts regional positioning technology. The positioning accuracy varies from tens of meters to hundreds of meters depending on the wireless technology used, and the location of personnel cannot be continuously known, making it impossible for mines to carry out refined personnel management. Work, with the demand for high-yield and efficient production in mines, the demand for accurate positioning in underground mines is becoming more and more intense. [0003] The wireless technologies used for positioning mainly include WIFI, Zigbee, RFID, and UWB. The algorithm basically adopts the TW-TOA ranging algorithm (two-way time difference method). The KJ69J mining ...
