Embodiment Construction

[0023] The present invention will be further described in detail below with reference to the drawings.

[0024] When the power consumption of the label battery 5 is seriously insufficient, and the chip of the label will not work normally, the battery voltage reading circuit 6 will automatically activate the insufficient voltage warning device 7 of the label card, such as a light or sound warning, such as image 3 . When communicating with the card reader 1, the tag card’s battery power information is sent to the card reader 1 through the tag’s chip 4 and the tag antenna 3. The operator of the card reader can deal with it as appropriate, or prompt to replace the battery or The charged label card battery is charged by electromagnetic waves, such as image 3 Shown.

[0025] After the card reader receives the information that the battery of the tag is insufficient and needs to be charged, the transmitting antenna 2 of the card reader 1 (acting as an electromagnetic wave charger here) s...

Abstract

In present active radio frequency recognition system, as horary extension in usage, quantity of electricity of battery is dropped so as to make operating distance reduced. Thus, user does not know quantity of electricity of battery. Card reader may not obtain information of label card so as to miss recognizing and recording label system. The invention can recognize electric quantity of battery of label card, and sands out a hint for replacing battery or not replacing battery. Electromagnetic wave charger (card reader) is utilized to charge labeled battery wirelessly through electromagnetic wave.

Description

Technical field [0001] The invention relates to information collection of the battery power of an active radio frequency identification tag card and a method for charging the battery. Background technique [0002] In recent years, automatic identification methods have been rapidly popularized and promoted in many service fields, in the sales of goods and logistics distribution, in the commercial sector, in the fields of production enterprises and material circulation. [0003] Automatic identification technology traditionally includes barcode, optical symbol recognition, voice recognition, fingerprint recognition and other biological information measurement methods, IC card, etc., each has its own advantages and disadvantages, and has been developed and applied differently. [0004] In recent years, one of the technically best solutions for automatic identification is to store data in a silicon chip. In daily life, IC cards (telephone IC cards, bank cards, etc.) with contact rows...
