AI Technical Summary

Problems solved by technology

At present, the main body of near-field communication is mostly the induction plate, and the receptors are mainly mobile terminals and identification cards. Due to the relatively large size of the mobile terminal, the distance requirement for near-field wireless communication is relatively small. When using mobile terminals for near-field wireless During communication, it is necessary to attach the mobile terminal only to the identification area of ​​the induction plate. Since one side of the mobile terminal is closely attached to the identification area of ​​the induction plate, the user can only hold the mobile terminal from the side or push it against To the back of the mobile terminal, it is easy to cause the mobile terminal to fall, and for the small-sized identification card, its contact range is small, and the identification card needs to be continuously positioned to realize the sensing, resulting in slow near-field communication identification efficiency

Embodiment 1

[0025] The present invention provides a multi-device near-field wireless communication system, such as figure 1 and figure 2 As shown, including the induction board 100 and the positioning device 200, the inside of the induction board 100 is a hollow structure, the inside of the induction board 100 of this embodiment is equipped with an NFC chip, adopts the principle of short-distance wireless communication, and its working principle is as known by those skilled in the art As is well known, the NFC chip provides a radio frequency field during the entire communication process. You can choose one of the transmission speeds of 106kbps, 212kbps or 424kbps to send data to another device. The other device is called an NFC target device without generating a radio frequency field. , while using load modulation technology, the data can be transmitted back to the initiating device at the same speed. The communication mechanism is compatible with contactless smart cards based on ISO1444...

Abstract

The invention relates to the technical field of near-field communication equipment, in particular to a multi-device near-field wireless communication system. It includes an induction plate and a positioning device. The interior of the induction plate is a hollow structure. The outer wall of the induction plate is provided with an induction groove. The two ends of the induction plate close to the induction groove are symmetrically provided with chute. The slide The groove passes through the outer surface of the induction plate, and the positioning device includes a pair of sliding columns, and the sliding columns are slidably connected in the sliding groove. The structural design of the present invention can not only locate the identification card and improve the identification efficiency of near-field wireless communication, but also complete the near-field wireless communication identification of the mobile terminal under the condition that the mobile terminal will not be dropped, and improve the use effect.

Description

technical field [0001] The invention relates to the technical field of near-field communication equipment, in particular to a multi-device near-field wireless communication system. Background technique [0002] Near field communication is an emerging technology. Devices using NFC technology can exchange data when they are close to each other. It is evolved from the integration of non-contact radio frequency identification and interconnection technology. Through a single chip It integrates the functions of inductive card reader, inductive card and point-to-point communication, and uses mobile terminals to realize applications such as mobile payment, electronic ticketing, access control, mobile identification, and anti-counterfeiting. At present, the main body of near-field communication is mostly the induction plate, and the receptors are mainly mobile terminals and identification cards. Due to the relatively large size of the mobile terminal, the distance requirement for nea...
