Abstract

The invention discloses a UWB-based external person positioning system and a method for an IDC computer room. The system comprises an access terminal, a positioning label, a plurality of one-dimensional positioning cells, a positioning and resolving module and an information management module. The access terminal is used for carrying out identity verification on an external person in the IDC computer room and inputting the information of the external person. The positioning label is worn on the external person, and is used for generating a TDOA message and a TOF ranging message, broadcasting the TDOA message and sending out the TOF ranging message. Each one-dimensional positioning cell comprises two UWB positioning base stations arranged at the two ends of the cabinet aisle of the IDC computer room, wherein the two UWB positioning base stations receive the TDOA message sent by the positioning label, and sending the time stamp of the received message to the positioning and resolving module. One UWB positioning base station is used as a specific base station to receive the TOF ranging message and send the result to the positioning and resolving module. The positioning and resolving module is used for resolving the data sent by the two UWB positioning base stations to obtain positioning coordinates of the positioning label.

Description

technical field

[0001] The present invention relates to the field of wireless real-time positioning technology, in particular to a technique for realizing one-dimensional or two-dimensional precise positioning of an IDC computer room by means of TDOA and TOF, and particularly to a UWB-based IDC computer room external personnel positioning system and method. Background technique

[0002] In addition to the global positioning system (GPS) application positioning in navigation and outdoor environments, people have not yet had a deep understanding of applications such as indoor positioning and short-distance positioning. The future trend of wireless positioning technology is to combine indoor positioning with outdoor positioning to achieve seamless and accurate positioning. The existing network technology cannot fully meet this requirement, and UWB technology stands out among many wireless positioning technologies due to its low power consumption, good anti-multipath effect, hig...
