Embodiment Construction

[0039] figure 2 It is a schematic structural diagram of an apparatus for controlling power on and off of a single board provided by an embodiment of the present invention. The device includes: a power supply slow start circuit 21 and a signal isolation control circuit 22 . The signal isolation control circuit 22 is connected to the power supply slow start circuit 21; the signal isolation control circuit 22 is used to convert the low-voltage side control signal into a high-voltage side control signal, and isolate the low-voltage side control signal from the high-voltage side control signal ; The power supply slow start circuit 21 powers on or off the load of the single board under the control of the high voltage side control signal. The low-voltage side control signal is sent by the control module in the communication device, and is used to control the power supply slow start circuit 21 to power on and off the single board.

[0040] In this embodiment, under the control of t...

Abstract

The embodiment of the invention relates to a single board, communication equipment, a device for controlling power on / off of the single board and a method thereof. The device for controlling power on / off of the single board comprises a power slow starting circuit and a signal isolation control circuit which are connected together, wherein, the signal isolation control circuit transforms a low-voltage side control signal into a high-voltage side control signal and isolates the low-voltage side control signal from the high-voltage side control signal; and the power slow starting circuit switches on / off the single board under control of the high-voltage side control signal. In the embodiment of the invention, on the basis of power supply of the existing single board in the equipment, the low-voltage side control signal sent by a control module is transformed into the high-voltage side control signal so as to control on / off of the power slow starting circuit, thus realizing power on / off control of the single board in the communication equipment under the condition of avoiding an additional external switching device.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a single board, communication equipment, a device and a method for controlling power on and off of a single board. Background technique [0002] At present, more and more attention is paid to the energy saving of communication equipment. Global telecom operators have put forward many requirements for energy saving and emission reduction for the long-term operation energy consumption of communication systems, including the static power consumption requirements of communication equipment. In order to meet the lower static power consumption requirements, the communication equipment adopts the power supply slow start circuit. By turning on and off the power supply slow start circuit to control the power on and off of the single board in the communication equipment, when the power supply slow start circuit is turned off to control the load power off of the single board in the c...
