The invention discloses a passive NFC positioning system comprising a terminal device, wherein an NFC communication module is installed in the terminal device, the terminal device is connected with aplurality of NFC monitoring devices, the terminal device is connected with a mobile phone terminal through a wireless network, and the mobile phone terminal is connected with a server. The invention further discloses a passive NFC positioning method. The invention has the advantages that the passive NFC positioning is adopted, the terminal device does not actively send signals for positioning, andcommunication is only performed within a range that can be detected by the monitoring device, and then the positioning is performed, in this way, the user privacy be effectively protected, the problem that the user does not want positioning but the device is secretly positioned can also be avoided, so that the security is greatly improved; and meanwhile the terminal device of the invention can berepeatedly used, can be used by different people, can also be used in different occasions and different environments, thus greatly improving the reusability and the application range of the device, and having the characteristics of high applicability.
Description
technical field [0001] The invention relates to the technical field of positioning systems, in particular to a passive NFC positioning system and a positioning method. Background technique [0002] Ordinary positioning systems generally use wireless methods such as GPS for positioning. GPS wants to accurately locate outdoors, but there will be relatively large deviations indoors. For some indoor positioning that requires high requirements, it cannot be completed. Indoor positioning generally uses wireless methods such as WiFi or Bluetooth for positioning, but WiFi or Bluetooth positioning requires both parties to enable WiFi or Bluetooth for positioning, and the terminal that needs to be positioned actively sends signals for positioning, which consumes a lot of power. Regardless of GPS positioning, Bluetooth, or WiFi positioning, they actively send signals for positioning. In some cases, issues such as user privacy are involved, and there is no guarantee that the user does n...
