Embodiment 1

[0045] 1. When the user holding the NFC active communication device 30 arrives in an unfamiliar city, he can connect to the remote server 40 through the mobile network, and download and update the local map database in time.

Embodiment 2

[0047]2. Update information such as road maintenance, traffic control, toilet maintenance and shutdown in some areas, as an important reference for navigation route calculation, to avoid the problem of navigation route failure.

Embodiment 3

[0049] 3. When the user holding the NFC active communication device 30 needs to call for help, the remote server 40 can send an alarm command message to a designated person or organization, so that rescuers can quickly arrive for rescue.

Abstract

The invention discloses an NFC position coordinate navigation system and a guiding method. The navigation system comprises an NFC active communication device and a plurality of NFC passive communication devices, the NFC passive communication devices are fixedly arranged at corresponding predetermined scene positions respectively, an NFC tag is installed in each NFC passive communication device, and the NFC tag stores an information code of the corresponding predetermined scene position; and the NFC active communication device comprises an NFC card reader and a mobile terminal, the mobile terminal stores a navigation database, and the mobile terminal receives an position information code read by the NFC card reader, and compares the position information code with the navigation database toobtain navigation information. The NFC position coordinate navigation system disclosed by the invention realizes the operations of device offline, non remote communication signal and non satellite positioning signal, and effectively solves the problem of positioning failure caused by external factors, and the NFC tag carries the information code of the corresponding predetermined scene position, so that targets different heights of the same coordinate can be identified, and the accuracy of the positioning i improved.

Description

technical field [0001] The invention relates to the technical field of positioning and guidance, in particular to an NFC position coordinate navigation system and a guidance method. Background technique [0002] Traditional positioning and guidance equipment mainly relies on satellite signals and wireless network signals to achieve guidance. Based on satellite navigation, it can accurately provide information such as target position and time. Nowadays, satellite navigation plays an important role in many fields of civil and military use, but this guidance The device also has the following defects: [0003] (1) Indoors or places where the wireless signal is interfered and cannot be covered, its functions are limited, resulting in errors or even failures in query positioning; [0004] (2) For marking targets at different altitudes (floors, etc.) within the same coordinate, it cannot be accurately identified. [0005] In view of this, it is urgent to improve the existing posi...
