[0002] In applications where a computer is remotely woken up, the network card (NIC) receives a remote wake-up signal and outputs a low-level signal to trigger the computer's power-on signal. The power-on signal is continuously pulled low by the NIC, meaning the power-on signal level goes from high to low. The computer's CPU executes the power-on process for the motherboard. Only when the NIC receives a signal that the motherboard has successfully powered on will it pull the power-on signal high again.
[0003] However, the power-on signal level of some domestically produced computers' CPUs needs to go from high to low and then back to high before the computer motherboard can be powered on, making the network card's remote wake-up function unusable. Utility Model Content

[0039] The following reference Figure 1 This application describes a remote network wake-up circuit and apparatus according to an embodiment of the present application.
[0040] This application provides a remote network wake-up circuit, including:
[0041] The network interface card (NIC) unit is used to output a low-level signal when a remote network wake-up signal is received.
[0042] The square wave generation unit is connected to the network card unit. The square wave generation unit is used to generate a square wave signal and output it to the CPU's power-on control terminal when a low-level signal is received.
[0043] In this embodiment, when the network card unit receives a remote network wake-up signal, it outputs a low-level signal. The square wave generation unit generates a square wave signal and outputs it to the CPU's power-on control terminal when it receives the low-level signal, so that the level of the CPU's power-on control terminal changes from high to low and then back to high, thereby executing the power-on process of the computer motherboard and realizing remote network wake-up.
[0044] In some embodiments of this application, the network interface card (NIC) unit may be an 8111H NIC.
[0045] In some embodiments of this application, the square wave generation unit may use a microcontroller to output a square wave signal or a square wave generator circuit.
[0046] In some embodiments of this application, the square wave generation unit includes:
[0047] The first switch module has its power-on control terminal grounded through the first switch module.
[0048] The first control module is connected to the network card unit and the control terminal of the first switch module. The first control module is used to control the first switch module to turn on when a low-level signal is received.
[0049] The second control module is connected to the first control module and is connected to the control terminal of the first switch module. The second control module is used to control the first switch module to disconnect after the first switch module is turned on.
[0050] In this embodiment, the power-on control terminal is at a high level. When a low-level signal is received, the first control module controls the first switch module to turn on, so that the power-on control terminal is grounded through the first switch module, thereby pulling down the level of the power-on control terminal. After the first switch module is turned on, the second control module controls the first switch module to turn off, so that the power-on control terminal returns to a high level, thereby realizing the output of a square wave signal.
[0051] In some embodiments of this application, the first switching module may employ switching elements such as MOSFETs or transistors.
[0052] In some embodiments of this application, both the first control module and the second control module can use a driving circuit to control the on / off state of the first switch module. For example, when the first switch module is a MOSFET, both the first control module and the second control module use a MOSFET driving circuit to control the on / off state of the first switch module.
[0053] In some embodiments of this application, such as Figure 1 As shown, the first switch module includes:
[0054] The first MOSFET Q1 has its drain connected to the power-on control terminal, its source grounded, and its gate connected to the first control module.
[0055] In this embodiment, when the first control module receives a low-level signal, it outputs a first control signal to the gate of the first MOS transistor Q1, thereby controlling the first switching module to turn on.
[0056] In some embodiments of this application, such as Figure 1 As shown, the first control module includes:
[0057] The second MOSFET Q3 has its drain connected to the power supply terminal, its source grounded, its gate connected to the power supply terminal, and its gate connected to the network card unit.
[0058] The first capacitor C2 has its first end connected to the power supply terminal and the control terminal of the first switch module, respectively, and its second end grounded.
[0059] In this embodiment, when the gate of the second MOSFET Q3 receives a low-level signal from the network card unit, the second MOSFET Q3 is turned off, and the power supply terminal charges the first capacitor C2. After the first capacitor C2 is charged, it outputs a high level to the control terminal of the first switch module, that is, it outputs a high level to the gate of the first MOSFET Q1, thereby turning on the first MOSFET Q1.
[0060] In some embodiments of this application, such as Figure 1 As shown, the second control module includes:
[0061] The drain of the third MOSFET Q2 is connected to the control terminal of the first switching module, and the source of the third MOSFET Q2 is grounded.
[0062] The control submodule is connected to the first capacitor C2 and the gate of the third MOSFET Q2. The control submodule is used to control the third MOSFET Q2 to turn on after the first switching module is turned on.
[0063] In this embodiment, after the first switch module is turned on, the control submodule controls the third MOSFET Q2 to turn on. The control terminal of the first switch module is grounded through the third MOSFET Q2, thereby turning off the first switch module, which in turn turns off the first MOSFET Q1, and the power-on control terminal returns to a high level.
[0064] In some embodiments of this application, such as Figure 1 As shown, the control submodule includes:
[0065] The second capacitor C1 has its first end connected to the power supply terminal and the gate of the third MOSFET Q2, and its second end grounded.
[0066] Diode D1, the anode of diode D1 is connected to the first terminal of the second capacitor C1, and the cathode of diode D1 is connected to the first terminal of the first capacitor C2.
[0067] In this embodiment, as the first capacitor C2 completes charging, the path of diode D1 stabilizes, and the power supply terminal begins to charge the second capacitor C1. After the second capacitor C1 is charged, it outputs a high level to the gate of the third MOSFET Q2, causing the third MOSFET Q2 to conduct.
[0068] In some embodiments of this application, such as Figure 1 As shown, the control submodule also includes:
[0069] The first resistor R4 has its first end connected to the power supply terminal, and its second end connected to the first end of the second capacitor C1.
[0070] In this embodiment, the power supply terminal charges the second capacitor C1 through the first resistor R4.
[0071] In some embodiments of this application, such as Figure 1 As shown, the first control module also includes:
[0072] The second resistor R5 has its first end connected to the power supply terminal.
[0073] The third resistor R6 has its first end connected to the second end of the second resistor R5 and the gate of the second MOSFET Q3, and its second end is grounded.
[0074] In this embodiment, the power supply terminal provides a high level to the gate of the second MOSFET Q3 through a voltage divider formed by the second resistor R5 and the third resistor R6, so that the second MOSFET Q3 remains in the conducting state before receiving a low level signal from the network card unit.
[0075] In some embodiments of this application, such as Figure 1 As shown, the first control module also includes:
[0076] The fourth resistor R2 has its first end connected to the first terminal, and its second end connected to the control terminal of the first switch module.
[0077] In this embodiment, after the first capacitor C2 is charged, it outputs a high level to the control terminal of the first switch module through the fourth resistor R2, thereby controlling the first switch module to conduct.
[0078] In addition, embodiments of this application provide a remote network wake-up device, including the remote network wake-up circuit as described above.
