Abstract

An elevator control system includes a control power supply, a computing core in communication with the control power supply, a communication power supply in communication with the computing core, and a sleep monitor in communication with the control power supply, the computing core, and the communication power supply. The sleep monitor is disposed to selectively turn on/off the control power supply and the computing core, and the sleep monitor is disposed to selectively change an operating state of the communication power supply to a low voltage state.

Claims

1. An elevator control system, comprising:

a control power supply;

a computing core in communication with the control power supply;

a communication power supply in communication with the computing core; and

a sleep monitor in communication with the control power supply, the computing core, and the communication power supply;

wherein, the sleep monitor is disposed to selectively turn on/off the control power supply and the computing core, and the sleep monitor is disposed to selectively change an operating state of the communication power supply to a low voltage state.

2. The system of claim 1, further comprising:

a plurality of remote devices in communication with the computing core and the sleep monitor.

3. The system of claim 2, wherein the computing core is disposed to, after a predetermined amount of time, request the sleep monitor to monitor a state of each device of the plurality of devices.

4. The system of claim 3, wherein the sleep monitor is configured to turn off the computing core and turn off the control power supply in response to the request.

5. The system of claim 1, further comprising an elevator car control portion.

6. The system of claim 5, wherein the elevator car control portion includes communication device in communication with the computing core, the sleep monitor, and the communication power supply.

7. The system of claim 6, wherein the elevator car control portion further includes an essential remote device and a non-essential remote device.

8. The system of claim 7, wherein the essential remote device is a door switch.

9. The system of claim 7 wherein the non-essential device is an alarm monitoring device.

10. The system of claim 7, wherein the computing core is disposed to, after a predetermined amount of time, request the sleep monitor to monitor a state of the essential device.

11. The system of claim 10, wherein the sleep monitor is configured to turn off the computing core and turn off the control power supply in response to the request.

12. The system of claim 1, further comprising a remote station, wherein the remote station includes an elevator request device.

13. The system of claim 12, wherein the computing core is disposed to, if after a predetermined amount of time of inactivity of the elevator request device has elapsed, request the sleep monitor to monitor a state of the elevator request device.

14. The system of claim 13, wherein the sleep monitor is configured to turn on the computing core and turn on the control power supply in response to the request.

15. The system of claim 1, further comprising:

a plurality of essential devices in communication with the computing core and the sleep monitor, wherein the essential devices include door switch devices and door request devices.

16. The system of claim 15, wherein the computing core is disposed to, after a predetermined amount of time, request the sleep monitor to monitor a state of each device of the plurality of essential devices.

17. The system of claim 16, wherein the sleep monitor is configured to turn off the computing core, turn off the control power supply, and switch the communication power supply to a low voltage state in response to the request.
