[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] The startup device provided by the embodiment of the present disclosure is applied to a network security device, which generally includes a processor.

[0036] Figure 1 A schematic diagram of a starting device provided for the implementation of the present disclosure is shown in FIG. Figure 1 As shown, the starting device 100 includes: a switch circuit 110, a single-chip microcomputer 120 and a power supply module 130. Among them, the first output end of the switch circuit 110 is electrically connected to the control end of the single-chip microcomputer 120, the control end of the switch circuit 110 is electrically connected to the first output end of the single-chip microcomputer 120, and the second output end of the switch circuit 110 is electrically connected to the input end of the power supply module 130. The second output end of the single-chip microcomputer 120 is electrically connected to the control end of the power supply module 130, the output end of the power supply module 130 is electrically connected to the power supply end of the network security device 200, and the data transmission end of the network security device 200 is electrically connected to the data transmission end of the single-chip microcomputer 120.

[0037] The power on / off circuit 110 is used to receive the power on mode selection signal Mode_SEL, and when the power on mode selection signal Mode_SEL is the manual power on mode selection signal Mode_SEL_MA, an interrupt signal KEY_DET is generated. The single chip computer 120 is used to generate a first voltage enable signal PV1_EN according to the interrupt signal KEY_DET. The power on / off circuit 110 is also used to output a first voltage V1 to the power supply module 130 under the action of the first voltage enable signal PV1_EN, so that the power supply module 130 supplies power to the network security device 200.

[0038] Exemplarily, the power-on mode selection signal Mode_SEL includes a manual power-on mode selection signal Mode_SEL_MA and an automatic power-on mode selection signal Mode_SEL_AU, and the power-on mode selection signal Mode_SEL received by the switch circuit 110 is the manual power-on mode selection signal Mode_SEL_MA or the automatic power-on mode selection signal Mode_SEL_AU. If the received power-on mode selection signal Mode_SEL is the automatic power-on mode selection signal Mode_SEL_AU, the switch circuit 110 can directly output the first voltage V1 to the power supply module 130, for example, the first voltage V1 is 12V.

[0039] If the received power-on mode selection signal Mode_SEL is the manual power-on mode selection signal Mode_SEL_MA, the power-on / off circuit 110 may generate an interrupt signal KEY_DET and transmit the interrupt signal KEY_DET to the microcontroller 120. For example, the interrupt signal KEY_DET may be a low level signal.

[0040] Continue to see Figure 1The second output terminal of the single-chip microcomputer 120 includes a core power enable signal terminal, a memory power enable signal terminal, a power management chip enable signal terminal and a second voltage enable signal terminal. Among them, the core power enable signal terminal can output a core power enable signal CORE_EN, the memory power enable signal terminal can output a memory power enable signal DDR_EN, the power management chip enable signal terminal can output a power management chip enable signal PMIC_EN, and the second voltage enable signal terminal can output a second voltage enable signal PV2_EN.

[0041] Correspondingly, the power supply module 130 includes a first control terminal, a second control terminal, a third control terminal and a fourth control terminal. Among them, the core power enable signal terminal is electrically connected to the first control terminal of the power supply module 130, the memory power enable signal terminal is electrically connected to the second control terminal of the power supply module 130, the power management chip enable signal terminal is electrically connected to the third control terminal of the power supply module 130, and the second voltage enable signal terminal is electrically connected to the fourth control terminal of the power supply module 130. In this way, the power supply module 130 can receive the core power enable signal CORE_EN, the memory power enable signal DDR_EN, the power management chip enable signal PMIC_EN and the second voltage enable signal PV2_EN.

[0042] When the single-chip microcomputer 120 receives the interrupt signal KEY_DET, under the action of the interrupt signal KEY_DET, the single-chip microcomputer 120 can generate a first voltage enable signal PV1_EN, and transmit the first voltage enable signal PV1_EN to the switch circuit 110. At the same time, the single-chip microcomputer 120 can generate a core power enable signal CORE_EN, a memory power enable signal DDR_EN, a power management chip enable signal PMIC_EN, and a second voltage enable signal PV2_EN, and output the core power enable signal CORE_EN, the memory power enable signal DDR_EN, the power management chip enable signal PMIC_EN, and the second voltage enable signal PV2_EN to the power supply module 130 according to the power-on timing of each module in the network security device 200.

[0043] When the single-chip microcomputer 120 does not receive the interrupt signal KEY_DET, the single-chip microcomputer 120 can generate a core power enable signal CORE_EN, a memory power enable signal DDR_EN, a power management chip enable signal PMIC_EN and a second voltage enable signal PV2_EN, and output the core power enable signal CORE_EN, the memory power enable signal DDR_EN, the power management chip enable signal PMIC_EN and the second voltage enable signal PV2_EN to the power supply module 130 according to the power-on timing of each module in the network security device 200.

[0044] In this way, regardless of whether the microcontroller 120 receives the interrupt signal KEY_DET, the core power enable signal CORE_EN, the memory power enable signal DDR_EN, the power management chip enable signal PMIC_EN and the second voltage enable signal PV2_EN will be generated, and according to the power-on timing of each module in the network security device 200, the core power enable signal CORE_EN, the memory power enable signal DDR_EN, the power management chip enable signal PMIC_EN and the second voltage enable signal PV2_EN will be output to the power supply module 130.

[0045] When the switch circuit 110 receives the first voltage enable signal PV1_EN, the switch circuit 110 outputs the first voltage V1 to the power supply module 130 under the action of the first voltage enable signal PV1_EN.

[0046] After receiving the first voltage V1, the power supply module 130 can convert the first voltage V1 into a first power supply voltage VDD1 adapted to the core power supply, a second power supply voltage VDD2 adapted to the memory power supply, a third power supply voltage VDD3 adapted to the power management chip, and a second voltage V2 adapted to other peripheral power supply modules. For example, the second voltage V2 is 3V. At the same time, the first power supply voltage VDD1, the second power supply voltage VDD2, the third power supply voltage VDD3, and the second voltage V2 are input into the network security device 200 through the corresponding power input port of the processor 210 to supply power to each module in the network security device 200.

[0047] In the disclosed embodiment, the startup device includes a switch circuit, a single-chip microcomputer and a power supply module, the first output end of the switch circuit is electrically connected to the control end of the single-chip microcomputer, the control end of the switch circuit is electrically connected to the first output end of the single-chip microcomputer, the second output end of the switch circuit is electrically connected to the input end of the power supply module, the second output end of the single-chip microcomputer is electrically connected to the control end of the power supply module, the output end of the power supply module is electrically connected to the power supply end of the network security device, and the data transmission end of the network security device is electrically connected to the data transmission end of the single-chip microcomputer. The switch circuit can receive a power-on mode selection signal, and when the power-on mode selection signal is a manual power-on mode selection signal, an interrupt signal is generated, the single-chip microcomputer can generate a first voltage enable signal according to the interrupt signal, and the switch circuit can also output a first voltage to the power supply module under the action of the first voltage enable signal, so that the power supply module supplies power to the network security device. In this way, by setting a single-chip microcomputer in the startup device, manual startup and automatic startup of the network security device can be realized, without setting a complex circuit, thereby reducing the circuit complexity of the startup device. In addition, since the cost of the single-chip microcomputer is relatively low, the cost of the startup device can be reduced.

[0048] In some embodiments, Figure 2A circuit diagram of a power on / off circuit provided for the implementation of the present disclosure, such as Figure 2 As shown, the switch circuit 110 includes: a first diode D1, a second diode D2, a first resistor R1 and a control module 111. Figure 1 and Figure 2 As shown, the anode of the first diode D1 is electrically connected to the control end of the microcontroller 120 and the first end of the first resistor R1, the second end of the first resistor R1 is used to receive the second voltage V2, the anode of the second diode D2 is used to receive the first selection signal KEY_SEL, and the cathode of the second diode D2 is electrically connected to the cathode of the first diode D1 and the start button interface JPWR.

[0049] The control end of the control module 111 is electrically connected to the first output end of the single-chip microcomputer 120 , the first input end of the control module 111 is electrically connected to the power input interface ATX, the second input end of the control module 111 is used to receive the second selection signal BOOT_SEL, and the output end of the control module 111 is electrically connected to the input end of the power supply module 130 .

[0050] The boot mode selection signal Mode_SEL includes a first selection signal KEY_SEL and a second selection signal BOOT_SEL. When the boot mode selection signal Mode_SEL is a manual boot mode selection signal Mode_SEL_MA, the voltages of the first selection signal KEY_SEL and the second selection signal BOOT_SEL are the same. When the boot mode selection signal Mode_SEL is an automatic boot mode selection signal Mode_SEL_AU, the voltage of the second selection signal BOOT_SEL is zero.

[0051] Exemplarily, when the boot mode selection signal Mode_SEL is the manual boot mode selection signal Mode_SEL_MA, the first selection signal KEY_SEL and the second selection signal BOOT_SEL are short-circuited. If the user does not trigger the start button, the anode voltage of the first diode D1 is a high voltage. If the user triggers the start button, the anode voltage of the first diode D1 jumps from a high voltage to a voltage, that is, the interrupt signal KEY_DET is generated.

[0052] Continue to see Figure 2, the control module 111 includes a first transistor Q1, a second transistor Q2, a second resistor R2, a third resistor R3, a fourth resistor R4 and a fifth resistor R5. Among them, the first end of the second resistor R2 is electrically connected to the first output end of the single-chip computer 120, the second end of the second resistor R2 is electrically connected to the control end of the first transistor Q1 and the first end of the third resistor R3, and the second end of the third resistor R3 and the first end of the first transistor Q1 are grounded. The second end of the first transistor Q1 and the first end of the fourth resistor R4 are used to receive the second selection signal BOOT_SEL, the second end of the fourth resistor R4 is electrically connected to the control end of the second transistor Q2 and the first end of the fifth resistor R5, the second end of the fifth resistor R5 is electrically connected to the second end of the second transistor Q2 and the power input interface ATX, and the first end of the second transistor Q2 is electrically connected to the input end of the power supply module 130.

[0053] Exemplarily, when the power-on mode selection signal Mode_SEL is the manual power-on mode selection signal Mode_SEL_MA, the power-on / off circuit 110 receives the first voltage enable signal PV1_EN. Under the action of the first voltage enable signal PV1_EN, the first transistor Q1 is in the on state, at which time, the control voltage of the second transistor Q2 can be pulled up to turn on the second transistor Q2. When the second transistor Q2 is in the on state, the power input interface ATX is connected to the input end of the power supply module 130.

[0054] Since the power input interface ATX can output the first voltage V1 , the first voltage V1 can be transmitted to the power supply module 130 through the second transistor Q2 .

[0055] In some embodiments, see Figure 2 The switch circuit 110 further includes a protection unit 112. The input end of the protection unit 112 is electrically connected to the input end of the power supply module 130, the output end of the protection unit 112 is grounded, and the control end of the protection unit 112 is used to receive the second selection signal BOOT_SEL.

[0056] For example, Figure 2 As shown, the protection unit 112 includes a sixth resistor R6 and a third transistor Q3. A first end of the sixth resistor R6 is electrically connected to the input end of the power supply module 130, a second end of the sixth resistor R6 is electrically connected to the second end of the third transistor Q3, a first end of the third transistor Q3 is grounded, and a control end of the third transistor Q3 is used to receive a second selection signal BOOT_SEL.

[0057] When the startup device 100 is normal or powered off, the second selection signal BOOT_SEL is pulled high, that is, the control voltage of the third transistor Q3 is pulled high, so that the third transistor Q3 is in a conducting state. At this time, the input end of the power supply module 130 is grounded through the sixth resistor R6. In this way, the protection unit 112 can release the filter capacitor in the startup device 100 to the ground after the startup device 100 is powered off.

[0058] At this time, the post-stage filter capacitor is discharged quickly, ensuring that the starting device 100 will not be affected by the residual voltage of the capacitor when starting the network security device next time, thereby ensuring that the network security device 200 can be started normally.

[0059] In some embodiments, Figure 3 A schematic diagram of another starting device provided for the implementation of the present disclosure is shown in FIG. Figure 3 As shown, the startup device 100 also includes a startup selection module 140. Figure 2 and Figure 3 As shown, the first output end of the startup selection module 140 is electrically connected to the anode of the second diode D2, the second output end of the startup selection module 140 is electrically connected to the second input end of the control module 111, and the third output end of the startup selection module 140 is electrically connected to the power input interface ATX.

[0060] For example, Figure 4 A schematic diagram of a startup selection module provided in an embodiment of the present disclosure, combined with Figure 3 and Figure 4 As shown, the boot selection module 140 includes a boot button 141 and a selection jumper cap 142, the output end of the boot button 141 is electrically connected to the boot button interface JPWR, the first pin of the selection jumper cap 142 is electrically connected to the anode of the second diode D2, the second pin of the selection jumper cap 142 is electrically connected to the second input end of the control module 111, and the third pin of the selection jumper cap 142 is grounded. The first pin of the selection jumper cap 142 outputs the first selection signal KEY_SEL, and the second pin of the selection jumper cap 142 outputs the second selection signal BOOT_SEL.

[0061] Exemplarily, the user can trigger the startup operation of the network security device 200 based on the startup selection module 140, and can also trigger the mode selection operation of the network security device 200 based on the startup selection module 140. When the user triggers the mode selection operation, the startup selection module 140 generates a corresponding startup mode selection signal Mode_SEL in response to the mode selection operation.

[0062] For example, when the user triggers the manual mode selection operation, the first pin and the second pin of the jumper cap 142 are short-circuited, and the startup selection module 140 generates the manual startup mode selection signal Mode_SEL_MA. When the user triggers the automatic mode selection operation, the third pin and the second pin of the jumper cap 142 are short-circuited, and the startup selection module 140 generates the automatic startup mode selection signal Mode_SEL_AU.

[0063] When the user triggers the startup operation, the startup selection module 140 generates a startup signal in response to the startup operation and inputs the startup signal to the power on / off circuit 110. Whether the startup mode selected by the user is a manual mode or an automatic mode, the network security device 200 needs to be started after receiving the startup signal.

[0064] In this way, the startup selection module 140 can generate a power-on mode selection signal in response to a mode selection operation of the user, and can also generate a startup signal in response to a startup operation of the user.

[0065] In some embodiments, see Figure 3 The starting device 100 further includes a single-chip microcomputer power module 150 , wherein an output end of the single-chip microcomputer power module 150 is electrically connected to a power end of the single-chip microcomputer 120 .

[0066] Exemplarily, no matter the starting device 100 is in working state or stopped working state, the MCU power module 150 inside the starting device 100 continues to supply power to the MCU 120 , so that the MCU 120 continues to monitor whether the power on / off circuit 110 outputs the interrupt signal KEY_DET.

[0067] In some embodiments, see Figure 3 The starting device 100 further includes a reset module 160 , an input end of the reset module 160 is electrically connected to a reset control signal end of the single chip microcomputer 120 , and an output end of the reset module 160 is electrically connected to a reset signal end of the network security device 200 .
