Benefits of technology

This patented technology allows for better management of electrical systems used within communications networks such as mobile phones or other electronic products. It uses an improved way to turn off certain parts during standby times while still allowing them to work properly even if they don't have any more data being transmitted over their network connection.

Problems solved by technology

This patented technical problem addressed in this patents describes how adding extra switches can increase the size and complexity of an existing system's power supply circuits while still meeting certain standards set forth during initial startup.

Embodiment Construction

[0025] 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.

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.
