Embodiment Construction

[0042] Embodiments of the present invention are further described below with reference to the accompanying drawings.

[0043] like figure 1 As shown, the indoor and outdoor positioning system based on electronic tags and databases of the present invention includes a reading device 1 and several electronic radio frequency tags 2; the electronic radio frequency tags 2 and the reading device 1 are identified by radio frequency.

[0044] The reading device 1 adopts a portable reader. If the wireless transmission frequency of the reading device 1 is high frequency, its reading distance is 0 to 20 cm; if the wireless transmission frequency of the reading device 1 is ultra-high frequency, Its reading distance is 0 to 2 meters. The reading device 1 is internally provided with a database, and the database records the geographic location information of the location of each electronic radio frequency tag 2 that is matched. The reading device 1 reads the position code information in the...

Abstract

The invention relates to an indoor/outdoor location system based on radio frequency identifications (RFID) and a database a location method thereof. The system comprises a reading device and a plurality of RFIDs; the RFID tags and the reading device are communicated by radio frequency to obtain encoding information in the RFIDs; the RFIDs are arranged on indoor/outdoor fixed or movable markers; and the reading device is a movable device. The system adopts the RFID and wireless reading devices, both of which are arranged in high density, thus more precise location can be realized, and areas which are hard to reach can be covered. Due to the adoption of the RFIDs, the invention has low arrangement cost and is more suitable for movable calculation; and the encoding content of the RFIDs is only associated with the position information, but not user information, thus the system does not actively leak the information of the reading device and the user, solves the problems of user position and privacy exposition and improves the security and the privacy of use for users.

Description

technical field [0001] The invention relates to a positioning system for logistics and navigation, in particular to an indoor and outdoor positioning system and a positioning method based on electronic tags and databases. Background technique [0002] Location Based Service (LBS: Location Based Service) is a field of electronic information industry with wide application and huge market value. The existing positioning systems include the following: [0003] 1. GPS positioning [0004] The Global Positioning System GPS is a navigation system based on medium-distance circular orbiting satellites. It can provide accurate positioning, speed measurement and high-precision time standard for most of the earth's surface. The GPS system consists of about 24 dedicated GPS satellites and ground support equipment. Civil GPS can achieve a positioning accuracy of about ten meters. [0005] The disadvantage is that the GPS accuracy is not high, and it cannot cover indoor and sheltered ou...
