Detailed Description

To further illustrate the various embodiments, the utility model provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the utility model and, together with the description, serve to explain the principles of the embodiments. Those skilled in the art will appreciate still other possible embodiments and advantages of the present invention with reference to these figures. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The utility model will now be further described with reference to the accompanying drawings and detailed description.

The embodiment discloses an anti-copy system of an IC access control card, as shown in FIG. 1, comprising: IC entrance guard's card 3, gate machine 4, IC-card reader 2 and management terminal 1.

The management terminal 1 comprises a first processing module 11, a first storage module 12, a first wireless communication module 13 and a USB communication module 14, wherein the first processing module 11 is respectively electrically connected with the first storage module 12, the first wireless communication module 13 and the USB communication module 14, the management terminal 1 is in communication connection with an IC card reader 2 through the USB communication module 14, the management terminal 1 writes an initial key into an IC access card 3 placed on the IC card reader 2 through the IC card reader 2, and simultaneously writes the initial key into the first storage module 12.

The management terminal 1 may employ a commonly used PC. The IC card reader 2 connected to the management terminal 1 is used for registering an IC card at an initial time, and writing an initial key into the IC access card 3, where all the IC cards of the initial key may be the same or different, and are not limited herein.

The chip model of the USB communication module 14 in this embodiment is CP2102, and its circuit diagram is shown in fig. 2.

The door phone 4 includes a second wireless communication module 42, a random dynamic password generation module 43, a second processing module 41, an electric control lock 45 and an IC card read-write module 44, the management terminal 1 and the door phone 4 are in communication connection through the first wireless communication module 13 and the second wireless communication module 42, and the second processing module 41 is electrically connected with the second wireless communication module 42, the random dynamic password generation module 43, the electric control lock 45 and the IC card read-write module 44 respectively.

The IC card read/write module 44 reads the key information in the IC access card 3 placed thereon in real time and sends the key information to the second processing module 41.

The second processing module 41 reads the key from the first storage module 12 of the management terminal 1 through the second wireless communication module 42 after receiving the key information in the IC access card 3 sent by the IC card read/write module 44, compares the received key information in the IC access card 3 with the key in the first storage module 12, sends a control instruction to the electric control lock 45 according to the comparison result to open the electric control lock, controls the random dynamic password generation module 43 to generate a random key according to the comparison result, sends the generated random key to the management terminal 1 through the second wireless communication module 42, and writes the generated random key into the IC access card 3 through the IC card read/write module 44.
