[0062] Embodiment 1

[0063] Please refer to Figure 1-8 , Embodiment 1 of this application provides a computer remote switch device. The device is used to remotely control the switch of a computer. An Ethernet connector J1 and a switch connector H1 are provided on the computer. The device includes a chip U1, a remote key module, a switch interface module, and a communication module. The remote key module is connected to the chip U1; the switch interface module is connected between the chip U1 and the switch connector; the communication module is connected between the chip U1 and the Ethernet connector J1.

[0064] The present utility model provides a computer remote switch device. The device includes a chip U1, a remote key module, a switch interface module, and a communication module. The remote key module is connected to the chip U1. The switch interface module is connected between the chip U1 and the switch connector provided on the computer. The communication module is connected between the chip U1 and the Ethernet connector provided on the computer. The chip U1 communicates with the computer through the communication module.

[0069] Further, the program burning module includes a fourth resistor R4 and a fifth resistor R5. One end of the fourth resistor R4 is connected to the first pin of the SWD emulator, and the other end of the fourth resistor R4 is grounded; one end of the fifth resistor R5 is connected to the second pin of the SWD emulator, and the other end of the fifth resistor R5 is connected to the positive pole of power supply VCC; wherein, the first pin of the SWD emulator is connected to the PA14 pin of the chip U1, the second pin of the SWD emulator is connected to the PA13 pin of the chip U1, the fourth pin of the SWD emulator is connected to the NRST pin of the chip U1, the fifth pin of the SWD emulator is connected to the positive pole of power supply VCC, and the sixth pin of the SWD emulator is grounded.

[0070] In a possible implementation manner, the device further includes a resistor R16 and a capacitor C12.

The negative pole of the power supply VCC is grounded, and the positive pole of the power supply VCC is respectively connected to the power supply terminal of the chip U1 and the program burning module. One end of the first capacitor C1 is connected to the positive pole of the power supply VCC, and the other end of the first capacitor C1 is grounded. One end of the bead FB1 is connected to the positive pole of the power supply VCC, and the other end of the bead FB1 is connected to the communication module. One end of the second capacitor C2 is connected to the other end of the bead FB1, and the other end of the second capacitor C2 is grounded. The third capacitor C3 is connected in parallel with the second capacitor C2.

[0073] In a possible implementation, the supply voltage of the power supply VCC is 3.3V.

[0074] Specifically, in the power supply module, the power supply VCC is filtered by the bead FB1 to filter out the spike pulses and interference in the power supply, making the power supply voltage more stable after the filtering process. The first capacitor C1 is used to filter the power supply VCC, and the second capacitor C2 and the third capacitor C3 are used to perform secondary filtering on the power supply voltage after being filtered by the bead.

[0075] As Figure 4 shown, in a possible implementation, the remote key module includes a first resistor R1, a switch S1, a second resistor R2, and a first light-emitting diode LED1. One end of the first resistor R1 is connected to the PB3 pin of the chip U1. One end of the switch S1 is connected to the other end of the first resistor R1, and the other end of the switch S1 is grounded. One end of the second resistor R2 is connected to the PB4 pin of the chip U1. The anode of the first light-emitting diode LED1 is connected to the other end of the second resistor R2, and the cathode of the first light-emitting diode LED1 is grounded.

[0076] Specifically, when the switch S1 is manually turned on, the level at the PB3 pin of the chip U1 is low. At this time, when the chip U1 detects that the level at the PB3 pin is low, it converts the levels at the PB4 pin and the PB5 pin to high. When the level at the PB4 pin is high, the circuit where the first light-emitting diode LED1 is located conducts, and LED1 lights up, so as to monitor the on and off of the switch S1 through the lighting and extinguishing of the first light-emitting diode LED1.

[0077] As Figure 3As shown, in a possible implementation, the switch connector includes a positive power pin, a negative power pin, a positive display light pin and a negative display light pin, the positive display light pin is connected to the positive power pin, and the negative display light pin is connected to the negative power pin, the switch interface module includes an optocoupler U3, a third resistor R3, a second light-emitting diode LED2, the input side positive pole of the optocoupler U3 is connected to the PB5 pin of the chip U1, the input side negative pole of the optocoupler U3 is grounded, the output side positive pole of the optocoupler U3 is connected to the positive power pin, and the output side negative pole of the optocoupler U3 is connected to the negative power pin; one end of the third resistor R3 is connected to the input side positive pole of the optocoupler U3, and the other end of the third resistor R3 is grounded; the anode of the second light-emitting diode LED2 is connected to the positive display light pin, and the cathode of the second light-emitting diode LED2 is connected to the negative display light pin.

[0078] It can be understood that the positive power pin (such as Figure 3 POWER+) and the negative power supply pin (as shown in Figure 3 The POWER-) shown in the figure is the positive and negative poles on the computer for starting up. When POWER+ and POWER- are connected, the computer starts up. When POWER+ and POWER- are disconnected, the computer shuts down.

[0079] Specifically, when the switch S1 is turned on, the PB5 pin outputs a high level, and the optocoupler U3 is turned on, so that the positive power pin and the negative power pin on the switch connector set on the computer are connected, so that the computer is turned on. Since the positive pin of the display light on the switch connector H1 is connected to the positive power pin, and the negative pin of the display light is connected to the negative power pin, when POWER+ and POWER- are connected, the second light-emitting diode LED2 is on, and the on and off of the second light-emitting diode LED2 can be used to monitor the on and off status of POWER+ and POWER- on the computer.

[0082] As a feasible way, the intermediate signal terminal of the signal receiver of the Ethernet connector J1 is connected to the other end of the bead FB1 for receiving a more stable power signal after filtering. The intermediate signal terminal of the signal transmitter of the Ethernet connector J1 is grounded after passing through the capacitor C4.

[0083] As a feasible way, in order to provide a stable clock signal, the fourth pin of the transceiver U2 is respectively connected to the third pin of the crystal oscillator X1 and one end of the capacitor C5, the fifth pin of the transceiver U2 is respectively connected to one end of the capacitor C8 and the first pin of the crystal oscillator X1, and the second pin, the fourth pin, the other end of the capacitor C5, and the other end of the capacitor C8 of the crystal oscillator X1 are grounded. The sixth pin of the transceiver U2 is grounded after passing through the capacitor C6.

When the computer finishes starting and running, the chip U1 realizes information communication between the computer and the chip U1 through the transceiver U2 of the communication module.
