Abstract

A method of operating an access control system including a remote control system configured to control a lock an a central control system configured to wirelessly communicate with the remote control system. The method includes inputting user data into a user identification reader of the remote control system, and in response to inputting user data, requesting updating a remote user list stored by the remote control system with a central user list stored by the central control system using a wireless communicator of the remote control system and a wireless communicator of the central control system. The method further includes comparing the user data with one of the remote user list and the central user list to determine whether to unlock the lock.

Claims

1. A method of operating an access control system including a remote control system configured to control a lock and a central control system configured to wirelessly communicate with the remote control system, the method comprising:

inputting user data into a user identification reader of the remote control system;

in response to inputting user data, requesting updating a remote user list stored by the remote control system with a central user list stored by the central control system using a wireless communicator of the remote control system and a wireless communicator of the central control system; and

comparing the user data with one of the remote user list and the central user list to determine whether to unlock the lock.

2. The method of claim 1, wherein the user data is compared with the remote user list, and wherein updating the remote user list is completed before comparing the user data with the remote user list.

3. The method of claim 2, further comprising determining whether updating the remote use list complete.

4. The method of claim 1, wherein the user data is compared with the remote user list generally when requesting updating the remote user list.

5. The method of claim 1, further comprising determining whether wireless communication is available between the central control system and the remote control system, wherein if wireless communication is unavailable between the central and remote control systems, the user data is compared with the remote user list before updating the remote user list, and if wireless communication is available between the central and remote control systems, the user data is compared with the remote user list after updating the remote user list.

6. The method of claim 5, wherein if wireless communication is available, determining whether updating the remote user list is complete.

7. The method of claim 1, wherein the user data is biometric user data.

8. The method of claim 1, further comprising supplying power to the wireless communicator of the remote control system from a battery in response to inputting the user data into the user identification reader.

9. The method of claim 1, further comprising restricting an amount of power supplied to the remote control system after comparing the user data with the one of the remote use list and the central user list.

10. The method of claim 1, wherein requesting updating the remote use list occurs after inputting user data and before comparing the user data with the one of the remote user list and the central user list.

11. The method of claim 1, wherein requesting updating the remote user list is initiated each time after inputting user data into the user identification reader of the remote control system.

12. The method of claim 1, further comprising transmitting the user data from the remote control system to the central control system, and wherein the user data is compared with the control user list to determine whether to unlock the lock.

13. The method of claim 1, further comprising transmitting the user data from the remote control system to the central control system, determining whether wireless communication is available between the remote control system and the central control system, if wireless communication is unavailable the use date is compared with the remote user list, if wireless communication is available the user data is compared with the central user list.

14. The method of claim 14, wherein if the user data is compared with the central user list to determine whether to unlock the lock and if the lock remains locked, then comparing the user data to the remote user list after updating the remote user list with the central user list.

15. A method of operating an access control system including a remote control system configured to control a lock and a central control system configured to wirelessly communicate with the remote control system, the method comprising:

inputting user data into a user identification reader of the remote control system;

in response to inputting user data, transmitting a request to update a remote user list stored by the remote control system with a central user list stored by the central control system using a wireless communicator of the remote control system and a wireless communicator of the central control system; and

determining whether wireless communication is available between the central control system and the remote control system, if wireless communication is available, updating the remote user list with the central user list and afterwards comparing the user data with the remote user list to determine whether to unlock the lock, and if wireless communication is unavailable, comparing the user data with the remote user list to determine whether to unlock the lock before updating the remote user list with the central user list.

16. The method of claim 15, wherein the user data is biometric user data.

17. The method of claim 15, further comprising supplying power to the wireless communicator of the remote control system from a battery in response to inputting the user data into the use identification reader.

18. The method of claim 17, further comparing restricting an amount of power supplied to the remote control system after comparing the user data with the remote user list.

19. The method of claim 15, wherein transmitting the request to update the remote user list is conducted each time after inputting user data into the user identification reader of the remote control system.

20. An access control system comprising:

a central control system configured to store a central user list and operable to update the central user list, the central control system including a wireless communicator operable to transmit the central user list; and

a remote control system configured to store a remote user list, the remote control system including,

a wireless communicator operable to receive the central user list from the central control system, and

a user identification reader operable to receive user data from a user of the remote control system, and wherein the remote control system initiates a wireless communication with the central control system in response to receipt of the user data to update the remote user list with the central user list.

21. The access control system of claim 20, wherein the user initiates the wireless communication when the user inputs the user data into the user identification reader.

22. The access control system of claim 20, wherein the user data is biometric user data.

23. The access control system of claim 20, wherein the remote control system further includes a battery that supplies power to the wireless communicator of the remote control system in response to the user inputting the user data into the user identification reader.
