Abstract
The invention provides a device for detecting a high-frequency radio frequency tag, which relates to the technical field of radio frequency identification. The device for detecting the high-frequency radio frequency tag comprises detecting antennae, wherein the detecting antennae consist of an upper antenna positioned on the top layer, an oscillating transmitting antenna positioned on the middle layer and a lower antenna positioned on the bottom layer; the upper antenna, the oscillating transmitting antenna and the lower antenna are round rings enclosed by metal wires; a lead-out wire at one end of the upper antenna round ring is connected with a lead-out wire at one end of the lower antenna round ring; and a lead-out wire at the other end of the upper antenna round ring and a lead-out wire at the other end of the lower antenna round ring form a receiving antenna capable of inducing voltage change. Compared with the prior art, the device for detecting the high-frequency radio frequency tag can fulfill the detection process without a specific chip protocol, so the device for detecting the high-frequency radio frequency tag has the characteristics of simple detection method and high detection accuracy.
Description
Technical field
The present invention relates to the radio RF recognition technology field, particularly be applicable to the pick-up unit of high-frequency radio frequency tag.
Background technology
The RFID technology is the abbreviation of Redio Frequency Identification, and the meaning is a radio frequency identification, and it is a kind of new technology of automatic identification field.The RFID label can be applied in multiple fields such as logistic track, certificate license be false proof.The RFID label comprises low frequency, high frequency and ultrahigh frequency label, and wherein high-frequency label is used at most, like certificate false proof, Bus Card and race admission ticket etc.
High-frequency label need detect contacting of antenna printing quality, chip and antenna aborning.The agreement of high-frequency label has ISO/IEC 14443 Type A, ISO/IEC 14443Type B, ISO/IEC 15693 etc. multiple, and the high-frequency label chip of a lot of producers and do not meet the ISO protocol specification.In the prior art, a fixed reader commonly used is sought the card operation, detects effective situation that is connected of antenna conducting, chip and the antenna of high-frequency label, and this method is complex operation not only, and accuracy rate is not high.
Summary of the invention
In order to solve the shortcoming that exists in the above-mentioned prior art, the purpose of this invention is to provide a kind of pick-up unit that is used for high-frequency radio frequency tag.It can be avoided concrete chip agreement and accomplish and detect, have detection method simple, detect the high characteristics of accuracy rate.
In order to reach the foregoing invention purpose, technical scheme of the present invention realizes as follows:
A kind of pick-up unit that is used for high-frequency radio frequency tag, it comprises exploring antenna.Its design feature is; Said exploring antenna comprises the last antenna that is positioned at top layer, the oscillating transmitting antenna in middle layer and the following antenna of bottom; Last antenna, oscillating transmitting antenna and following antenna all are the circular rings that surrounded by metal wire, and last antenna, oscillating transmitting antenna and following antenna all are that horizontal positioned is parallel.One end extension line of last antenna circular rings is connected with an end extension line of following antenna circular rings, and the other end extension line of last antenna circular rings and following antenna circular rings forms the receiving antenna that induced voltage changes.
Use the aforesaid detection method that is used for the pick-up unit of high-frequency radio frequency tag, the steps include:
1. the last antenna of exploring antenna is placed tested RF tag, and following antenna is placed qualified RF tag;
2. if the then tested RF tag of the non-inductive voltage of receiving antenna is qualified, if receiving antenna has the then tested RF tag of induced voltage defective;
3. when tested RF tag is defective, take down the qualified RF tag that antenna is placed away;
4. if receiving antenna has the then tested radio-frequency label antenna short circuit of induced voltage, if the then tested radio-frequency label antenna of the non-inductive voltage of receiving antenna opens circuit or label chip is connected with antenna inactive.
The present invention is owing to adopted said structure; Utilize label to the balanced type of exploring antenna coupling detection principle, utilize the induced voltage of the balance receiving antenna that changes differential configuration to come situation such as antenna conducting, chip and the antenna of label effective is connected are detected.Compare with prior art, the present invention need not to consider concrete chip agreement, have detection method simple, detect the high characteristics of accuracy rate.
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the process flow diagram of detection method of the present invention.
Embodiment
Referring to Fig. 1, the present invention includes the exploring antenna of forming by the following antenna 3 of the oscillating transmitting antenna 2 in the last antenna 1 that is positioned at top layer, middle layer and bottom.Last antenna 1, oscillating transmitting antenna 2 and following antenna 3 all are the circular rings that surrounded by metal wire; One end extension line of last antenna 1 circular rings is connected with an end extension line of following antenna 3 circular rings, and the other end extension line of last antenna 1 circular rings and following antenna 3 circular rings forms the receiving antenna that induced voltage changes.
Use the detection method step of apparatus of the present invention to be:
1. the last antenna 1 of exploring antenna is placed tested RF tag, and following antenna 3 is placed qualified RF tag;
2. if the then tested RF tag of the non-inductive voltage of receiving antenna is qualified, if receiving antenna has the then tested RF tag of induced voltage defective;
3. when tested RF tag is defective, take down the qualified RF tag that antenna 3 is placed away;
4. if receiving antenna has the then tested radio-frequency label antenna short circuit of induced voltage, if the then tested radio-frequency label antenna of the non-inductive voltage of receiving antenna opens circuit or label chip is connected with antenna inactive.
