Abstract

The invention relates to an active RFID indoor positioning system and positioning method used for emergency command guidance. The indoor positioning system includes a positioning data transmission module, a processing display module and RFID tags; the RFID tags adopt passive tags and are installed in indoor key positions in advance; and the positioning data transmission module reads ID informationof the RFID tags and sends to the processing display module to analyze and display the rescuer serial numbers, positions and moving path. The indoor positioning system provided by the invention has the advantages of being simple in principle, easy to realize, convenient to carry, easy to maintain, rapid in laying and low in cost, has low dependency on external conditions, can provide relatively good positioning accuracy and corresponding speed, is wide in coverage area, and combined with existing positioning technology, can realize seamless indoor and outdoor positioning of multiple scenes ofplants, mine fields, storage, rescue, counter-terrorism and the like.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to an active RFID indoor positioning system and positioning method for emergency command and guidance. Background technique [0002] Accurate indoor positioning is of great significance for public safety, commercial applications, and military applications such as factories, mines, warehousing, rescue, anti-terrorism, and individual soldiers. However, the indoor environment is very complex, so the indoor non-line-of-sight effect (signal propagation will be blocked by obstacles such as walls, partitions, and ceilings) causes signal reflection, refraction, diffraction, and multipath, which make traditional positioning methods unable to meet the requirements. The application requirements of indoor high-precision positioning make indoor positioning extremely challenging. In the current indoor RFID technology, the positioning mode adopted is: personnel wear RFID tags, the RFID positi...
