Abstract
The utility model provides a detector used for high frequency radio frequency tag, relating to the radio frequency identification technical field. The utility model comprises a probe antenna composed of an upper antenna arranged at the top, oscillation transmitting antenna at the interlayer and a lower antenna at the bottom. The upper antenna, the oscillation transmitting antenna and the lower antenna are all round rings surrounded by metal wires. Outgoing line at one end of the upper antenna round ring is connected with the outgoing line at one end of the lower antenna round ring, and the outgoing line at the other end of upper antenna round ring and the outgoing line at the other end of the lower antenna round ring form a receiving antenna with variable induced voltage. Compared with the prior art, the utility model can escape concrete chip protocol to complete detection and has the characteristics of simple detection method and high detection accuracy rate.
Description
Technical field
The utility model relates to the radio RF recognition technology field, particularly is 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, as 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 utility model provides a kind of pick-up unit that is used for high-frequency radio frequency tag.It can be avoided concrete chip agreement and finish detection, have detection method simple, detect the high characteristics of accuracy rate.
In order to reach the foregoing invention purpose, the technical solution of the utility model realizes as follows:
Be used for the pick-up unit of high-frequency radio frequency tag, it comprises exploring antenna.Its design feature is, described 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, and last antenna, oscillating transmitting antenna and following antenna all are the circular rings that surrounded by metal wire.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 radio-frequency (RF) tag, and following antenna is placed qualified radio-frequency (RF) tag;
2. if the then tested radio-frequency (RF) tag of the non-inductive voltage of receiving antenna is qualified, if receiving antenna has the then tested radio-frequency (RF) tag of induced voltage defective;
3. when tested radio-frequency (RF) tag is defective, take down the qualified radio-frequency (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 utility model 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 situations such as antenna conducting, chip and the antenna of label effective is connected are detected.Compare with prior art, the utility model need not to consider concrete chip agreement, have detection method simple, detect the high characteristics of accuracy rate.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the process flow diagram of the utility model detection method.
Embodiment
Referring to Fig. 1, the utility model comprises the exploring antenna of being made up of 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 utility model Device Testing method step to be:
1. the last antenna 1 of exploring antenna is placed tested radio-frequency (RF) tag, and following antenna 3 is placed qualified radio-frequency (RF) tag;
2. if the then tested radio-frequency (RF) tag of the non-inductive voltage of receiving antenna is qualified, if receiving antenna has the then tested radio-frequency (RF) tag of induced voltage defective;
3. when tested radio-frequency (RF) tag is defective, take down the qualified radio-frequency (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.
Claims (1)
1. the pick-up unit that is used for high-frequency radio frequency tag, it comprises exploring antenna, it is characterized in that, described exploring antenna comprises the last antenna (1) that is positioned at top layer, the oscillating transmitting antenna (2) in middle layer and the following antenna (3) of 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.
