Abstract

A peripheral controller for an access control system according to one embodiment includes a reader interface, a Power over Ethernet circuit, a processor, and a memory. The reader interface is configured to be communicatively coupled to at least one credential reader. The Power over Ethernet (PoE) circuit is configured to receive power over an Ethernet cable for powering the peripheral controller. The memory includes a plurality of instructions stored thereon that, in response to execution by the processor, causes the peripheral controller to analyze credential data received via the reader interface make an access control decision based on the analyzed credential data.

First claim

What is claimed is:

1. An access control system, comprising:
a credential reader configured to receive access credentials via a wireless communication connection with a credential device;
an electronic lock including a lock mechanism configured to control access through a barrier; and
a peripheral controller separate from the electronic lock, separate from the credential reader, and comprising a reader interface communicatively coupled to the credential reader, a Power over Ethernet (PoE) circuit that receives power over an Ethernet cable for powering the peripheral controller, a plurality of output relays, and a plurality of test buttons, wherein each test button of the plurality of test buttons corresponds with an output relay of the plurality of output relays and is configured to directly test the corresponding output relay, and wherein the peripheral controller is configured to:
analyze credential data received from the credential device via the reader interface;
make an access control decision based on the analyzed credential data to determine whether to grant access to a user of the credential device; and
transmit a control signal to the electronic lock to unlock the lock mechanism in response to a determination to grant access to the user.

2. The access control system of claim 1 , wherein the plurality of output relays of the peripheral controller comprises a first output relay electrically coupled to the lock mechanism;
wherein to transmit the control signal to the electronic lock comprises to transmit the control signal to the first output relay and to transmit a corresponding signal to the lock mechanism to cause the lock mechanism to unlock.

3. The access control system of claim 2 , wherein the lock mechanism comprises an electrical door strike.

4. The access control system of claim 1 , wherein the peripheral controller further comprises a line power interface configured to receive line power from an external power supply and an Ethernet interface configured to receive Ethernet data communication and Power-over-Ethernet (PoE) from a remote device.

5. The access control system of claim 1 , further comprising a management server configured to communicate with the peripheral controller via at least one of a Bluetooth connection, a Wi-Fi connection, or an Ethernet connection to exchange at least one of a firmware update, audit data, access control database data, or an access control schedule.

6. The access control system of claim 1 , further comprising a mobile device configured to communicate with the peripheral controller via a Bluetooth connection and a Wi-Fi connection; and
wherein the Bluetooth connection or the Wi-Fi connection is selected based on a file size of data to be exchanged between the peripheral controller and the mobile device.

7. The access control system of claim 1 , wherein the peripheral controller further comprises:
a plurality of inputs electrically coupled to corresponding input components of the peripheral controller, and
a plurality of user-configurable switches, wherein each input of the plurality of inputs is user-configurable by a user during operation of the peripheral controller as normally open or normally closed based on a corresponding switch of the plurality of switches.

8. A peripheral controller for an access control system, the peripheral controller comprising:
a reader interface configured to be communicatively coupled to at least one credential reader separate from the peripheral controller;
a Power over Ethernet (PoE) circuit configured to receive power over an Ethernet cable for powering the peripheral controller;
a plurality of output relays;
a plurality of test buttons, wherein each test button of the plurality of test buttons corresponds with an output relay of the plurality of output relays and is configured to directly test the corresponding output relay;
a processor; and
a memory comprising a plurality of instructions stored thereon that, in response to execution by the processor, causes the peripheral controller to (i) analyze credential data received via the reader interface and (ii) make an access control decision based on the analyzed credential data.

9. The peripheral controller of claim 8 , wherein the plurality of instructions further causes the peripheral controller to transmit a control signal associated with unlocking a lock mechanism that secures a barrier.

10. The peripheral controller of claim 9 , wherein the plurality of output relays comprises a first output relay electrically coupled to the lock mechanism;
wherein to transmit the control signal comprises to transmit a control signal to the first output relay; and
wherein the first output relay transmits a corresponding signal to the lock mechanism to cause the lock mechanism to unlock.

11. The peripheral controller of claim 10 , wherein the lock mechanism comprises an electrical door strike.

12. The peripheral controller of claim 8 , further comprising:
a line power interface configured to receive line power from an external power supply; and
an Ethernet interface configured to receive Ethernet data communication and Power-over-Ethernet (PoE) from a remote device.

13. The peripheral controller of claim 8 , further comprising communication circuitry configured to facilitate communication with a management server via at least one of a Bluetooth connection, a Wi-Fi connection, or an Ethernet connection; and
wherein the plurality of instructions further causes the peripheral controller to communicate with the management server via the communication circuitry to exchange at least one of a firmware update, audit data, access control database data, or an access control schedule.

14. The peripheral controller of claim 8 , wherein the reader interface supports communication with each of the at least one credential reader via one of an RS-485 interface and a Wiegand interface and control lines at a given time.

15. The peripheral controller of claim 14 , further comprising a hardware selector to select between the RS-485 interface and the Wiegand interface.

16. The peripheral controller of claim 8 , further comprising wireless communication circuitry configured to facilitate communication with a mobile device via a Bluetooth connection and a Wi-Fi connection; and
wherein the plurality of instructions further causes the peripheral controller to communicate with the mobile device via one of the Bluetooth connection or the Wi-Fi connection selected based on a file size of data to be exchanged between the peripheral controller and the mobile device.

17. The peripheral controller of claim 8 , wherein the plurality of test buttons comprises a lock test button, an alarm test button, and an auxiliary test button.

18. The peripheral controller of claim 8 , further comprising:
a plurality of output status LEDs, wherein each output status LED of the plurality of output status LEDs corresponds with an output relay of the plurality of output relays and is configured to indicate a status the corresponding output relay; and
wherein the output status LED of a corresponding output relay is changed by activation of the test button associated with corresponding output relay.

19. The peripheral controller of claim 8 , further comprising:
