Embodiment Construction
[0014] The method of applying radio frequency identification tag technology to firefighters' indoor positioning in the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:
[0015] Arrange passive RFID tags in areas where people may arrive in large buildings, such as fire exits, main entrances and exits, stair elevators, etc., and store the globally unique identification code information (ID information for short) of the tag in the tag. And calibrate the indoor position coordinates (two-dimensional or three-dimensional) of each RFID tag and its installation direction information in the two-dimensional floor distribution map or three-dimensional design drawings of the building. The antenna requirement of the RFID tag used in this system is linearly polarized. When installing RFID tags, the direction of the tags can be set cyclically according to a certain rule, such as 0-45-90-135 degrees. The installation po...
