Abstract

The utility model provides a passive electric label, which belongs to the field of electric identification products. In the utility model, a butterfly type directional antenna and an intelligent passive microchip which are specially designed are connected to be made into a label of which the shape, the size and the thickness are similar to that of a bookmark, and the label is stuck to the surface of a detected object and is used for receiving a signal sent through an intelligent reader, and sends out or writes the information stored in the label. In consideration of anti-counterfeit and anti-theft requirements, the external surface of the label is packaged by paper and is carved with an anti-tear line; when the label is stuck, the antenna and the chip are disconnected if the label is torn off, and the label is out of work; an unique identification code is solidified in the chip and can not be changed manually, thereby ensuring the uniqueness of the label; moreover, the label can be dynamically detected at long distance and read and write information, and the application field of the label is wide.

Description

Passive electronic label

Technical field:

The utility model belongs to the electronic mark product scope, specially refers to a kind of passive electronic label.

Background technology:

Label miscellaneous has been used very extensive at industry-by-industry, mainly be divided into several big classes: one, traditional: resemble the price tag, vehicle annual inspection label in shop etc., discern by human eye; Two, bar code: as the goods in supermarket etc., carry out pattern recognition, closely detect by special-purpose read write line; Three, active formula electronic tag: as the early stage logical card of vehicle speed,, supply with label, so that the recognition of devices at charge station place is let pass by the power supply of cigar lighter on the car; Four, passive electronic label: as IC-card, the bank card of microarray strip, magnetic stripe etc. also are with specialized equipment closely or contact operation.

More than the test mode of several labels all be to adopt traditional hand inspection mode, otherwise be exactly employing equipment closely or contact operation, if think to detect at a distance passive electronic label, also be difficult at present accomplish, also be a new technical task in the world, the utility model is exactly the innovative development that carries out at this problem.

Summary of the invention:

The utility model technical issues that need to address are, in the past for the detection of various labels, all can only be closely or the contact operation, be difficult to satisfy the remote requirement that detects, in order to overcome this weak point, just need to redesign a kind of remote operated New-type label that is convenient to; Therefore, the purpose of this utility model provides a kind of passive electronic label, and it is to be used for a kind of product of identify objects.Realize that the technical scheme that the utility model purpose is adopted is, it is connected custom-designed butterfly type directional antenna with the Intelligent Passive microchip, be made into the label of the similar size of shape such as same bookmark, thin and thick, stick on the surface of testee, be used to accept the signal that intelligent reader is issued, and the information of its storage inside sent or write, reach information exchange, realize detecting at a distance.

Consider false proof, antitheft requirement, its appearance adopts the papery encapsulation, is carved with and prevents tearing line, after the stickup, in case will tear it down, will cause antenna to be connected disconnection with chip, and label lost efficacy; Each chip internal has all solidified unique identification code, can not artificially change, and has guaranteed the uniqueness of label.

It has following characteristics: 1) low in energy consumption; Highly sensitive, have extremely strong directivity: 2) uniqueness, inside solidification unique identification code; 3) passive, the life-span is long, 100,000 times able to programme; 4) papery encapsulation brings the design of non-dismountable property; 5) miniaturization.

Description of drawings:

With reference to Fig. 1, represent passive electronic label synoptic diagram described in the utility model, 1 is special-purpose butterfly type directional antenna among the figure; The Intelligent Passive microchip in centre position is 2.

Embodiment:

Paper surface in the passive electronic label outer enclosure produces required pattern, and engrave anti-tear line after, be equipped with glue in the front of label, vertically stick on the body surface that needs to detect then and get final product.

Claims

1. a passive electronic label has the shape of bookmark size, thin and thick, it is characterized in that: this label appearance adopts the papery encapsulation, and Intelligent Passive microchip and coupled special-purpose butterfly type directional antenna are contained in inside.

2. according to right 1 described passive electronic label, it is characterized in that: in described encapsulation made of paper in appearance, be carved with and anti-tear line and scribble stickup glue in the front.

3. according to right 1 described passive electronic label, it is characterized in that: all solidified unique identification code in described Intelligent Passive microchip inside.
