Technical field
The utility model relates to the code reader technical field, particularly a kind of code reader that is used to handle the I.D. with the RFID element that interrelates with I.D..
Background technology
Eas detects the existence be placed on compact electronic device on the article or in the article or that carried by the people who is paid close attention to, and is used for retail trade or library, is used for finding and stops the transfer that theft or other of article are gone beyond one's commission.These known devices are generally label or sign, and they generally only comprise the information relevant with the existence of article.RFID is a kind of contactless automatic identification technology, and it adopts contactless by radiofrequency signal, and recognition objective object and obtain related data automatically need not manual intervention.Wireless version as bar code, though on manufacturing cost than existing bar code height, but rfid system has the not available waterproof of bar code, antimagnetic, low temperature resistant, long service life, read that distance is big, the canned data change waits advantage freely on the label, can work in the various environment, its application will reduce the logistics transportation of article and the expense that the stock handles greatly, bring revolutionary variation for industries such as retail, logistics.The RFID technology utilizes wireless radio frequency mode to carry out the noncontact bidirectional data transfers between reader and label, to reach the purpose of Target Recognition and exchanges data.Abroad, REID has been widely used in various fields such as industrial automation, business automation, communications and transportation control and management, and label (radio-frequency card) is widely used in systems such as public transport, subway Fare Collection System, parking fee collective system, gate control system, attendance checking system and purchase and consumption.Equally, the RFID technology also is applied in passport identification, but in the identification of I.D., use, still rests on the manual detection stage, and the accuracy and the reliability of its detection are low.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, easy to use, and accurately and reliably based on the I.D. code reader of RFID technology.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of I.D. code reader based on the RFID technology, comprise the code reader main body that matches with I.D. with RFID element, it is characterized in that: described code reader main body mainly by the interrogation source of box body and interior setting thereof, can the transmitter of energy or information be provided and receive the receiver of identifying information from the RFID element to the RFID element, the top opening slot of box body, the embedded transparent cover plate that is connected to of hole slot, the edge setting positioning seat corresponding of this cover plate with I.D..
As further specifying of such scheme, the RFID element comprises the RFID label, and the RFID interrogation source is connected with the antenna corresponding with the RFID element, and this antenna is " ∞ " shape.
Described positioning seat is arranged in the antenna 3cm distance of RFID element in described I.D. code reader main body.
The communication frequency of described RFID element and RFID interrogation source is 13.56MHz, 915MHz or 115MHz.
Described box body is provided with the PORT COM of external computing machine, and catoptron and camera head are installed in the box body.
The quantity of described catoptron is two, and the mirror outer periphery correspondence is provided with one or two light source.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts the RFID interrogation source to inquire after and acquired information from the RFID element that interrelates with I.D., the signal of being responsible between the two by antenna transmits, and antenna is configured " ∞ " shape, and this antenna has the antinoise signal countermeasure set, prevents that effectively the signal of other RFID reader from stealing.Compare with existing manual detection, the accuracy of inquiring after information greatly improves, and simple in structure, and is easy to use.

Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of I.D. code reader of the utility model based on the RFID technology, comprise the code reader main body that matches with I.D. with RFID element, the RFID element comprises the RFID label, the code reader main body mainly by the RFID interrogation source 2 of box body 1 and interior setting thereof, can the transmitter of energy or information be provided and receive receiver, the calculation element of identifying information from the RFID element to the RFID element, calculation element is handled the information that interrogation source obtained, and any calculation element in this area all can use on this code reader.The top opening slot 5 of box body 1, the hole slot 5 embedded transparent cover plates 6 that are connected to, the positioning seat 4 that the edge setting of this cover plate 6 and I.D. 3 are corresponding, RFID interrogation source 2 can transmit enough energy to provide power to RFID element and subsequent communications thereof for the RFID element, in order to guarantee that code reader can read information from the RFID element, and can prevent that simultaneously the information of other code reader from stealing or intercepting and capturing, RFID interrogation source 2 is connected with antenna 7 by electric wire, present embodiment has the shape of " ∞ " font of being made up of two annular sections with antenna 7 formations, two annular sections are respectively first loop and second loop, and first loop and second loop are created on the reversed magnetic field that cancels each other out in the certain distance and allow short-range communication.Therefore, the RFID code reader is difficult to pick up information of being write by the RFID element in the I.D. or any other instruction that sends to the RFID element from I.D. at certain distance.Yet this antenna 7 still allows to carry out short-range communication between I.D. and code reader.Under the situation of the antenna distance in the distance code reader less than 0.5m, then the RFID element in the I.D. can be read, if under the situation of antenna 7 distances greater than 0.5m in I.D. 3 and the code reader, then code reader is difficult to communicate by letter with the RFID element in the I.D..For this reason, the positioning seat of the hole slot periphery of the top of box body and the distance of code reader are in 3cm, so that suitable the communicating by letter with the RFID element of antenna.
The transmitter of RFID interrogation source is exported radiofrequency signal by antenna, thereby generating makes the RFID element return the radiofrequency signal of having carried from the RFID component information, transmitter is initiated communication, and makes amplifier come driven antenna, communicates by letter with the RFID element with the signal of modulation output.RFID element and RFID interrogation source can communicate under a lot of frequencies, under the frequency as 13.56MHz, 915MHz or 115MHz.
Described I.D. code reader also comprises catoptron and the camera head that is installed in the box body, box body is provided with the PORT COM 8 that connects computing machine, number of mirrors in the box body is two, the mirror outer periphery correspondence is provided with one or two light source, is used for the image that provides by transparent cover plate 6 is provided light.In the face of the image of the information in the I.D. front of transparent cover plate 6 is reflected on first catoptron, be reflected to then on second minute surface, captured by camera head thereafter.Thereafter, optical information is by the Computer Processing that is connected with camera head.
The utility model is not limited to the foregoing description, and any those skilled in the art can do numerous modifications and variations, under the spirit that does not break away from utility model, all in the claimed scope of the utility model.
