Abstract

The invention discloses a WiFi-based indoor positioning and verification system, which includes: at least one RFID reader, which is scattered in the positioning area; at least three wireless APs, which are scattered in the positioning area; mobile devices, connected to at least three The wireless AP machine obtains the wireless signal strength; the positioning server collects the wireless signal strength and uses a differential algorithm to locate the mobile device; among them, the mobile device is equipped with an RFID electronic tag; when the mobile device enters the preset signal range of the positioning area, the RFID The electronic tag sends out the RFID signal; at least one RFID reader receives the RFID signal to confirm that the mobile device is within the preset signal range. The mobile device uses WiFi positioning. When the mobile device enters the preset signal range, the RFID electronic tag is activated to send a radio frequency signal; the RFID reader obtains the radio frequency signal and confirms that the mobile device is within the preset signal range, indicating that the mobile device is within the preset signal range. There are no false reports about the device.

Description

technical field [0001] The invention relates to the technical field of indoor positioning, in particular to a WiFi-based indoor positioning and verification system. Background technique [0002] With the rapid changes of the times and the rapid development of science and technology, the quality and efficiency of information services have been improved, and the degree of interference is small, which has played a very important role in people's life, work and scientific research. Indoor positioning technology is very practical, has a large expansion space, and has a wide range of applications. In complex environments, such as libraries, gymnasiums, underground garages, and goods warehouses, it can quickly locate people and objects. [0003] For the sign-in link of an event, the consumption of manpower is huge, and a large amount of labor costs for completing this link can be saved through technical means. The entire electronic sign-in process is fast and convenient, allowing p...
