Elevator control system with sleep monitor
摘要:
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.
