Embodiment Construction

[0035] Referring to the accompanying drawings, the vibration measurement electronic tag and system based on current generation described in the present invention will be described in detail:

[0036] figure 1 instruction of:

[0037] ginseng figure 1 As shown, the structure of a vibration measurement electronic tag 100 based on current generation described in the present invention is described here, which is an embodiment. The vibration measuring electronic tag 100 based on current generation includes three main parts, namely, the A-side vibrating object 200 , the B-side vibrating object 300 , and the RFID chip 400 .

[0038] The aforementioned A-side vibrating object 200 has an A-side current induction structure 210 encapsulated thereon; the aforementioned B-side vibrating object 300 has a B-side current induction structure 310 encapsulated thereon. An induced current can be generated between the A-side current induction structure 210 and the B-side current induction struc...

Abstract

The invention provides a current generation-based vibration measuring type electronic tag and a system thereof, and belongs to the field of electronic technology. The electronic tag comprises a party A vibration object, a party B vibration object and an RFID chip, wherein the party A vibration object is used as a reference during vibration measurement; the party B vibration object is a measured object encapsulated in the party A vibration object; and the RFID chip is used for receiving induced current generated by the relative motion of the party A vibration object and the party B vibration object. The electronic tag system comprises a vibration detecting electronic tag, a radio frequency detector and a radio frequency signal processing unit, wherein the radio frequency signal processing unit is used for processing and converting a radio frequency signal detected by the radio frequency detector into vibration data. The electronic tag and the system thereof have the advantages of simple structure, low cost, and convenient use, and contribute to the popularization and application of the RFID as the RFID is increasingly loved and received by people.

Description

technical field [0001] The invention belongs to the field of electronic technology and relates to an RFID technology. Background technique [0002] RFID, or electronic tags. According to the energy supply method, it is divided into passive RFID, active RFID, and semi-active RFID. Passive RFID has a short reading and writing distance; active RFID can provide a longer reading and writing distance and requires battery power, but is suitable for long-distance reading and writing. [0003] The working principle of RFID is: the electronic tag can receive the radio frequency signal sent by the reader, the radio frequency signal is a changing electromagnetic field, and an induced current can be obtained in the changing electromagnetic field. The energy obtained by the induced current can trigger the storage chip set in the electronic tag to send out the product information stored in the chip. For active electronic tags, electromagnetic signals of a certain frequency can be active...
