Abstract
The invention discloses a method for realizing a visual card reader. The card reader has the tag reading and picture taking functions, wherein the picture taking function is provided by a common digital camera or can be realized in manners of infrared, rays and the like. A working mode that the picture taking and tag identification are carried out synchronously is provided by a main control module of the system; under such working mode, the main control module processes the picture taking and tag identification as an undivided body; and moreover taken pictures and read tag ID (Identity) are mapped together.
Description
Technical field
The card reader, particularly this card reader that the present invention relates to the data of storing in the label are read can also be taken pictures to object, possess simultaneously in the label mapping with acquisition photo and its corresponding object.
Background technology
RF identification (RFID; Radio Frequency Identification) technology is a kind of noncontact tag information Recognition transmission technology; Rfid system generally is made up of card reader (or read write line), label and antenna; It is to utilize wireless radio frequency mode to carry out the noncontact bidirectional data communication, to reach the purpose of Target Recognition and swap data.Difference according to frequency of operation; Rfid system can also be divided into four types of low frequencies (LF), high frequency (HF), ultrahigh frequency (UHF), microwave (MW); Because super high frequency technique (UHF) and microwave technology (MW) have advantages such as operating distance is far away, communication speed is fast, cost is low, size is little, become the emphasis of current rfid system development.
The functional module that card reader generally comprises: main control module, RF receiving and transmission module, data storage module, interface section, power module, clock module and acousto-optic reminding module etc.
1) main control module is responsible for control, is coordinated each functional module, realizes data acquisition and command response.
2) RF receiving and transmission module sends to the collection that main empty module realizes data to data through antenna demodulation, the signal that sends of decoding RF tag, or with secret order and digital coding, modulation after antenna transmission is given label, realization is to the write operation of label.
3) power module need provide various different voltages usually, and the power of radio-frequency module is bigger, and it is high-power therefore to require power supply to export.
4) data that arrive of data storage module storage of collected forward the data to computing machine after waiting to receive the transmission data command of computing machine again.
5) interface section provides the various interface that card reader externally provides.
6) acousto-optic module reminding module operation performance.
7) time or the real-time time of the collection of clock module video data.
Main modular such as camera mainly contains camera lens, imageing sensor, puts in advance, AGC, A/D, synchronous generator, picture signal form circuit constitute.The principle of work of camera is: the subject reflection ray, propagate into camera lens, and to sensor, sensor produces the electric signal of a width of cloth picture through lens focus, passes through the processing of A/D again, just can change into electric signal the digital picture of one width of cloth picture.
Summary of the invention
The object of the present invention is to provide a kind of visual card reader, this card reader also has the function of taking pictures simultaneously except comprising the ability of traditional reading tag.Particularly the main control module of card reader with reading tag with take pictures integratedly, label ID that the picture that obtains taking pictures and card reading module are obtained shines upon together.
In addition, the reader operating mode that the object of the present invention is to provide a kind of photograph and identification to carry out together is when card reader is worked under this mode of operation; For same object; In the time of can only all completing successfully these two things continuously, this operation of just saying so is effectively, otherwise all is invalid.
Card reader of the present invention has following structure in order to solve above-mentioned problem:
1) a kind of card reader has the function of taking pictures with reading tag.The function of taking pictures can be to take a picture with common digital camera head, also can take a picture with the means that infrared, ray etc. can be formed images.
2) a kind of card reader; Its main control module can provide the mode of operation of taking pictures and carrying out together with reading tag; And main control module with these two child-operations as a bulk treatment; Promptly an object is taken a picture, reading tag the time, must these two operations be completed successfully continuously, otherwise regard as invalid.
Description of drawings
Below card reader of the present invention is described.
Fig. 1 is the block scheme of the major part structure of expression card reader of the present invention.Visual card reader construction module 1 shown in Figure 1 has shown the universal architecture of visual card reader, mainly comprises main control module, RF receiving and transmission module, power module, data memory module, photo module, clock module, acousto-optic module and interface section.Wherein the present invention is characterized in main control module shown in Figure 12 control RF receiving and transmission modules 3 and photo module 4 co-ordinations; Overcome the defective that traditional card reader can only reading tag, made card reader of the present invention except taking pictures for the object of corresponding label the reading tag.
Fig. 2 be expression card reader of the present invention when taking pictures the mode of operation of carrying out together with reading tag, the workflow diagram of card reader.Object A1 of selection shown in Figure 2 is meant from the pending object of a pile and selects one arbitrarily that the mode of selection can be artificial, also can adopt the mode of automatic search; Shown in Figure 2 to object A photo module 2 with read the label model 4 on the object A, can change according to the demand of actual items, and if these two modules handle is not same object, it is invalid that whole operation will be regarded as.
Embodiment
Embodiment of the present invention: according to the functional module that requires among Fig. 1, particularly increase photo module, and main control module can provide and takes pictures and discern the mode of operation of carrying out together.
The advantage of this method: in recognition object, integrated function of taking pictures to object, and in the tag number mapping that the picture of gained and object is corresponding, become an integral body.
Claims (6)
1. the implementation method of a visual card reader is characterized in that, said method comprises:
Card reader has reading tag and the function of taking pictures simultaneously;
Card reader has one and coordinates reading tag and the system of taking pictures.
2. according to the implementation method of right 1 described visual card reader, it is characterized in that said method comprises:
Having reading tag simultaneously is meant to the identification of a label with to taking pictures of corresponding object and can carries out simultaneously with the function of taking pictures.
3. according to the implementation method of right 1 described visual card reader, it is characterized in that said method comprises:
Card reader has a major function of coordinating reading tag and the system of taking pictures: will become an indivisible integral body for the identification of a labeled object and these two steps of taking pictures.
4. according to the implementation method of right 3 described visual card reader, it is characterized in that said method comprises:
