Abstract

This comprises a control centre (1) via which, in a coded means of key and user identification (2) an identifying code of the means themselves, an identifying code of the user, a first set of information referring to opening operations permitted in reading means (3) for permitting access, a third set of information referring to invalidated means (2) and a second set of information, provided by reading means (3) corresponding to the different openings performed are recorded. It avoids connection between the control centre (1) and the reading means (3) with the means (2) constituting the communication means between them.

Claims

1. ACCESS CONTROL SYSTEM, comprising

reading means for key coded means and user identification means,

the reading means including storage means of its own identification code,

said reading means being connected to governing means of opening means of an access device;

a control centre for storage and management of the operating data of the system,

the key coded means and user identification means including an identifying code of the means themselves and an identifying code of the user, introduced via the control centre;

wherein

the key coded means and user identification means comprise storage means of

a first set of information, provided by the control centre and referring to the permitted opening operations of the opening means,

a second set of information, provided by the reading means, referring to different openings,

and a third set of information, provided via the control centre, referring to invalidated key coded means and user identification means (blacklist);

the third set of information being stored by the reading means each time a key coded means and user identification means are read, in order to allow the reading means to open or deny the opening on the basis of the first and third sets of information provided by the key coded means and user identification means;

deleting means of the first set of information whose key coded means and user identification means belong to an invalid user, to restrict the access of the key to the opening means which it originally had access to.

2. ACCESS CONTROL SYSTEM, according to claim 1, wherein

the storage means of the reading means comprise a fourth set of information for identifying a plurality of reading means;

the key coded means and user identification means store the fourth set of information, provided by the control centre, in order to permit opening of the opening means corresponding to the plurality of the reading means identified by the fourth set of information, all this via the same key coded means and user identification means once read by the corresponding reading means.

3. ACCESS CONTROL SYSTEM, according to claim 1, wherein the key coded means and user identification means comprise a fifth set of information selected from among timetables and calendars corresponding to openings of access devices;

and in that the storage means of the reading means store the fifth set of information when reading the key coded means and user identification means, in order to automatically open the opening means.

4. ACCESS CONTROL SYSTEM, according to claim 1, wherein the third set of information referring to the key coded means and user identification means comprises a list of identifying codes of the key coded means and user identification means which have been invalidated.

5. ACCESS CONTROL SYSTEM, according to claim 2, wherein the fourth set of information comprises at least one code, each of which is associated with a plurality of reading means.

6. ACCESS CONTROL SYSTEM, according to claim 1, 4 or 5, wherein the first set of information referring to permitted opening operations in the opening means comprises information selected from the identification codes of the readers to which access is permitted, the codes associated to a plurality of reading means to which access is permitted, timetables and calendars in which opening is permitted, information for modifying the information contained in the storage means of the reading means and combinations thereof.

7. ACCESS CONTROL SYSTEM, according to claim 1, wherein the second set of information referring to different openings carried out by the opening means comprises information selected from the identification code of the reader which has been accessed, a user identification code, date and time at which each opening has been carried out and combinations thereof.

9. ACCESS CONTROL SYSTEM, according to claim 1, wherein at least one of the reading means is connected to the control centre for exchange of the first, second, third, fourth and fifth sets of information between the key coded means and user identification means, and the control centre.

8. ACCESS CONTROL SYSTEM, according to previous claims, wherein the control centre stores the second set of information of the key coded means and user identification means when these are read in the control centre, and it eliminates said second set of information of the key coded means and user identification means.
