Abstract

Described herein are systems and methods for managing access control devices. In overview, an access control device is configured to function on the basis of an applied set of configuration data. For example, the manner in which the device processes an access request is dependent on the configuration data. A device according to an embodiment of the present invention is configured to locally maintain plurality of uniquely applicable sets of configuration data. Each set, when applied, causes the device to function in accordance with a respective mode of operation. The device is configured to change which set of configuration data is applied in response to a predetermined command, thereby allowing the device to shift between modes of operation relatively quickly and without the need to download additional configuration data. In some cases, the modes of operation correspond to threat levels, and the use of such access control devices allows a change in threat level to be applied across an access control environment quickly and with minimal bandwidth requirements.

Claims

1. An access control device including:

a processor for allowing the execution of software instructions, including software instructions for processing data indicative of access requests on the basis of an applied set of configuration data and selectively allowing or denying the respective requests;

a memory module coupled to the processor, the memory module storing data indicative of the software instructions and configuration data, wherein the configuration data stored by the device includes a plurality of uniquely applicable sets of configuration data, wherein each set, when applied, causes the device to function in accordance with a respective mode of operation;

a communications interface that is configured for receiving data indicative of a command to change modes of operation, wherein in response to the command the software instructions cause the device to cease applying a current one of the sets of configuration data and commence applying a different one of the sets of configuration data identified by the command; and

an input that is configured to, when operating in a disconnected state;

interact with an access control token, wherein the access control token maintains time stamped data indicative of a mode of operation associated with a specific one of the uniquely applicable sets of configuration data;

in the case that predefined requirements are met, adopt the mode of operation associated with the specific one of the uniquely applicable sets of configuration data; and

in the case that the predefined requirements are not met, continue to function in accordance with a current mode of operation associated with a current one of the uniquely applicable sets of configuration data, and write to the access control token updated time stamped data indicative of the current mode of operation associated with the current one of the uniquely applicable sets of configuration data.

2. The access control device access according to claim 1 wherein the plurality of sets of configuration data include:

a first set of configuration data that, when applied, causes the device to function in a first mode of operation; and

a second set of configuration data that, when applied causes the device to function in a second mode of operation;

such that when the device is functioning in the first mode of operation, the communications interface is configured for receiving data indicative of a command to change to the second mode of operation, and in response to the command the software instructions cause the device to cease applying the first set of configuration data and commence applying the second set of configuration data.

3. The access control device access according to claim 1 wherein the configuration data includes an n^th set of configuration data that, when applied, causes the device to function in an n^th mode of operation.

4. The access control device access according to claim 1 wherein each set of configuration data corresponds to a respective threat level.

5. The access control device according to claim 4 wherein:

a first set of configuration data, when applied, causes the software instructions process data indicative of access requests in accordance with a first threat level; and

a second set of configuration data, when applied, causes the software instructions process data indicative of access requests in accordance with a second threat level.

6. The access control device access according to claim 1 wherein each set of configuration data describes respective authentication/authorisation settings.

7. The access control device access according to claim 1 wherein each set of configuration data describes respective access permission settings.

8. The access control device access according to claim 1 wherein each set of configuration data describes settings in relation to one or more of the following:

visitor access card rules;

supervisor requirements;

minimum occupancy requirements;

default access control states;

other access related rules and surveillance settings.

17. An access control system including:

a plurality of access control devices according to claim 1; and

a central server in communication with the plurality of access control devices via a network, wherein the central server is configured to provide to the plurality of devices data indicative of a command to change modes of operation, wherein in response to the command, the devices each cease applying a current set of configuration data and commence applying a different set of configuration data identified by the command.

18. A method for controlling an access control environment, wherein the access control environment includes a plurality of access control devices according to claim 1, the method including providing to the devices data indicative of a command to change modes of operation, wherein in response to the command the software instructions cause the device to cease applying a current set of configuration data and commence applying a different set of configuration data identified by the command, wherein the different set of configuration data is locally stored at the devices.

9. A method performable by an access control device, the method including:

applying a first set of configuration data stored locally at the access control device, the first set of configuration data, when applied, causing the device to function in a first mode of operation;

whilst functioning in the first mode of operation, processing data indicative of access requests on the basis of the first set of configuration data;

receiving data indicative of a command to change to a second mode of operation;

in response to the command, ceasing application of the first set of configuration data and commencing application of a second set of configuration data, wherein the second set of configuration data is also stored locally at the access control device, the second set of configuration data, when applied, causing the device to function in the second mode of operation;

whilst functioning in the second mode of operation, processing data indicative of access requests on the basis of the second set of configuration data;

whilst functioning in a disconnected state, reading an access control token, wherein the access control token maintains time stamped data indicative of a mode of operation associated with a specific one of the uniquely applicable sets of configuration data;

in the case that predefined requirements are met, adopt the mode of operation associated with the specific one of the uniquely applicable sets of configuration data; and

in the case that the predefined requirements are not met, continue to function in accordance with a current mode of operation associated with a current one of the uniquely applicable sets of configuration data, and write to the access control token updated time stamped data indicative of the current mode of operation associated with the current one of the uniquely applicable sets of configuration data.
