The CD-ROM drive controller that has rfid interrogator of the present invention, the power module power supply that utilizes Computer optical disc drive to carry adds the RFID module for reading and writing; Central Control Module and supporting communication module not with the CD insertion CD-ROM drive of RFID label, are then pressed common CD-ROM drive work; In case having the CD of label gets into after the CD-ROM drive; The RFID module for reading and writing is read the information on the label or is write, and label information and CD-ROM drive information can be used, thereby realizes processing and protection to optical disc information; In the hope of reaching the effect of effective control CD read and write, realize the object of the invention.
Characteristics of the present invention can consult this case graphic and below better embodiment detailed description and obtain to be well understood to.
Description of drawings
Fig. 1 is the structure principle chart that has the CD-ROM drive controller of rfid interrogator of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1; The CD-ROM drive controller that has rfid interrogator of the present invention; Comprise CD-ROM drive control circuit 10; In CD-ROM drive control circuit 10, also be provided with information transmission that the Central Control Module 200, of a RFID module for reading and writing 100, a control RFID module for reading and writing 100 work reads RFID module for reading and writing 100 and give the communication module 300 and the power module 400 for RFID module for reading and writing 100, Central Control Module 200 and communication module 300 power supplies of computing machine; RFID module for reading and writing 100, Central Control Module 200 and communication module 300 are connected mutually successively, and power module 400 is connected with RFID module for reading and writing 100, Central Control Module 200 and communication module 300 respectively.
Under the effect of Central Control Module 200, realize tag read in order efficiently, communicate through communication module 300 and computing machine, reach effective control CD read and write, realize the CD function of keeping secret.
The RFID label is built in the CD, after CD inserts CD-ROM drive, reads and writes the operation of judgement; Information on the RFID label can be encrypted message or read and write judgement information, and at Central Control Module 200 (or main frame) corresponding deciphering or read-write operation arranged.
The RFID label adopts passive label, is packaged in the transparent plastic part of cd centre.
RFID module for reading and writing 100 uses the special chip and the necessary peripheral components that meet specific occasion RFID standard to build; Corresponding protocol requirement and necessary peripheral components; Realize that inductive coil drives and echoed signal demodulation work; Completion obtains the data in the RFID chip, and sends Central Control Module 200 to the read-write process of RFID chip.
