Hand-held terminal, interactive indoor tour-inspection system and interactive indoor positioning method

Abstract

The invention relates to an interactive positioning technology, in particular to a hand-held terminal, an interactive indoor tour-inspection system and an interactive indoor positioning method. The interactive indoor tour-inspection system comprises a hand-held terminal, a plurality of locating tags, an upper computer and a network communication module, wherein the hand-held terminal is provided with a trigger, a receiver and a network transmission module; the locating tags are arranged indoors and used for receiving a trigger signal sent by the hand-held terminal and transmitting an answering signal including position information of the locating tags; the network communication module is arranged indoors and used for completing information interaction between the network transmission module and the upper computer. The trigger and the receiver are arranged on the hand-held terminal, the locating tags are dual-mode tags, and the advantages of water resistance, pressure resistance, long service life, accurate positioning and low false alarm rate are achieved.

Description

technical field [0001] The invention relates to an indoor positioning system and a positioning method thereof. Background technique [0002] In many occasions, indoor positioning technology is often used to monitor and locate moving targets. There are many types of existing indoor positioning technologies, mainly including: [0003] 1. Traditional RFID tag positioning uses active radio frequency tags and their readers for positioning. The radio frequency tags are distributed in the positioning area and continuously transmit signals outward. Personnel carry tag readers. When they reach the signal coverage area, they read The card reader will read the tag information to determine the location of the person. [0004] The disadvantages of this scheme are: the accuracy is not high, and the signal transmission range is wide. When the reader is located within the coverage of several tag signals, it is easy to misreport the location information; in addition, the signal of the radi...

Problems solved by technology

[0004] The disadvantages of this scheme are: the accuracy is not high, and the signal transmission range is wide. When the reader is located within the coverage of several tag signals, it is easy to misreport the location information; in addition, the signal of the radio frequency tag is not stable enough, and the signal of each tag There is a large difference in the transmission distance, and it is easily affected by the surrounding environment; finally, the active tag continuously transmits signals, consumes a lot of power, and has a short service life

This kind of solution needs to arrange a large number of cameras, which requires a large amount of on-site construction and high cost. Its advantage is that the picture is intuitive, but it is difficult for managers to view the location information of multiple people at a glance. It is inconvenient when positioning multiple people. heavy maintenance workload
