Positioning system

Abstract

The invention discloses a positioning system, which comprises a positioning base station, a plurality of positioners and a plurality of active tags. The positioning base station comprises a first processor which controls a first radio frequency module to realize communication with a positioner; The second processor is in communication connection with the first processor and used for controlling the second radio frequency module; The first radio frequency module connected with the first processor; The second radio frequency module connected with the second processor, wherein the number of the first processor and the number of the first radio frequency modules are both more than one, and one first processor controls one first radio frequency module to receive and transmit RF signals; And theplurality of positioners which communicate with the positioning base station and the plurality of active tags, wherein the plurality of positioners respectively measure the distance of one active tagand return a measurement result to the positioning base station, and the positioning base station calculates the accurate position of the active tag according to the measurement result returned by the plurality of positioners in combination with the known geographic positions of the plurality of positioners. The positioning system d has the advantages of good performance, faster and more efficient processing speed, low power consumption and low hardware cost.

Description

technical field [0001] The invention belongs to the field of radio frequency technology, and in particular relates to a positioning system. Background technique [0002] The base station is a public mobile communication base station, which is a form of radio station, and refers to a radio transceiver station that transmits information between mobile phone terminals through a mobile communication switching center in a certain radio coverage area. The construction of mobile communication base stations is an important part of the investment of mobile communication operators in my country. The construction of mobile communication base stations is generally carried out around factors such as coverage, call quality, investment benefits, difficulty of construction, and convenient maintenance. With the development of mobile communication network services in the direction of dataization and packetization, the development trend of mobile communication base stations must also be broadb...

AI Technical Summary

Problems solved by technology

[0004] From macro base stations, micro base stations, pico base stations to distributed base stations, the volume of base stations is gradually miniaturized, and installation and deployment are more flexible, but there are still problems such as high hardware costs, weak anti-interference ability and incomplete coverage, resulting in low positioning accuracy, etc. shortcoming
