Problems solved by technology

The common point of these positioning technologies is that high-frequency electromagnetic waves are used as the carrier for positioning measurement and information transmission. The positioning range is large, but the positioning accuracy is low. The highest positioning accuracy can only reach 6 to 10 meters.
Satellite positioning methods and cellular mobile network positioning methods cannot accurately locate indoors or underground such as subway stations where there is no satellite signal. What they locate is the coordinates of the network terminal in space. For devices without network terminals such as seats on the street Or indoor cabinets, the above two positioning systems cannot achieve positioning

Abstract

The invention discloses a local ground precise positioning system and a using method thereof. The local ground precise positioning system comprises a matrix scanning circuit, floor tiles, a routing controller, a network server, a management terminal and a positioning terminal; the using method comprises the following steps: (1), laying the matrix scanning circuit; (2), establishing network connection; (3), precisely positioning. According to the local ground precise positioning system and the using method thereof, provided by the invention, the matrix scanning circuit is laid below the floor tiles, when a user walks on the floor tiles, the pressure can be transmitted to node switches of the matrix scanning circuit through the floor tiles to switch on the node switches, the trampling condition of the floor tiles within a limited range is collected and sent back to a user terminal through the Internet, and the user terminal determines the exact location within a limited range according to the self-motion condition. With the adoption of the local ground precise positioning system and the using method thereof, provided by the invention, the precise positioning within the range of smaller than 1 mm can be realized, precise positioning can also be realized in indoor and underground places where precise positioning is hardly realized traditionally, so that the local ground precise positioning system and the using method thereof can be applied to the fields like security and protection, intelligent home and positioning and navigation.

Description

technical field [0001] The invention relates to a positioning system and its application method, in particular to a local ground precise positioning system and its application method. Background technique [0002] At present, the commonly used positioning methods mainly include satellite positioning technology and cellular mobile positioning technology. Satellite positioning technology is divided into GPS positioning system and Beidou positioning system according to different principles. The common point of these positioning technologies is that high-frequency electromagnetic waves are used as the carrier for positioning measurement and information transmission. The positioning range is large, but the positioning accuracy is low. The highest positioning accuracy can only reach 6 to 10 meters. Satellite positioning methods and cellular mobile network positioning methods cannot accurately locate indoors or underground such as subway stations where there is no satellite signal...
