[0002] The one-way import solution is a security solution for importing sensitive information from low-level to high-level.

[0030] The technical solution proposed in the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0031] Figure 1 A one-way introduction device is provided in the embodiment of the present application. Figure 1 As shown, the device provided in the embodiment of the present application mainly includes: a sending end 1, a receiving end 2, a unidirectional transmission module 3, and a USBHUB module 4.
[0032] During the unidirectional transmission process, the first input interface 111 of the CPU 11 of the transmitting end in the transmitting end 1 is connected to an external U disk, optical drive, mobile hard disk and other mobile storage devices, so that the CPU 11 of the transmitting end can read data (as an example, the process of the CPU 11 of the transmitting end reading data can be that the transmitting end 1 includes a USB input interface 13, and the first input interface 111 of the CPU 11 of the transmitting end is connected to the USB input interface 13 through a USB bus to obtain the transmission data of the external USB; in addition, the USB input interface 13 is connected to the first VCC pin 114 and the first ground pin 115 in the CPU 11 of the transmitting end, so as to provide stable power to the USB input interface 13), and during the data reading process, the first power module 12 provides a stable power supply to the CPU 11 of the transmitting end. (As an example, the first power VCC pin 121 of the first power module 12 is connected to the first VCC pin 114; the first power ground pin 122 of the first power module 12 is connected to the first ground pin 115, so as to realize that the first power module 12 provides a stable power supply to the CPU 11 of the transmitting end).
[0033] In addition, in this embodiment, the first clock interface 116 can be set on the sending end CPU 11, and then connected to the first clock circuit module 117 to provide a clock signal for the sending end CPU 11.
[0034] After the sending end CPU 11 reads the external data, it transmits the read data to the unidirectional transmission module 3 through the first output interface 112. Here, the first output interface 112 for transmitting data to the unidirectional transmission module 3 can be a SATA interface. When the first output interface 112 is a SATA interface, the third input interface 31 of the unidirectional transmission module 3 is connected to the first output interface 112 through a SATA bus.
[0035] The read data is transmitted to the receiving end 2 through the third output interface 32 of the unidirectional transmission module 3 (the third output interface 32 here is connected to the second input interface 211 to realize data transmission). The second input interface 211 can use a SATA interface. When the second input interface 211 is a SATA interface, the third output interface 32 of the unidirectional transmission module 3 is connected to the second input interface 211 through a SATA bus. In the process of the receiving end 2 obtaining data, the second power supply module 22 provides a stable power supply to the receiving end CPU 21. (As an example, the second power supply VCC pin 221 of the second power supply module 22 is connected to the second VCC pin 214; the second power supply ground pin 222 of the second power supply module 22 is connected to the second ground pin 215, thereby realizing that the second power supply module 22 provides a stable power supply to the receiving end CPU 21).
[0036] In addition, in this embodiment, the second clock interface 216 can be set on the receiving end CPU 21, and then connected to the second clock circuit module 217 to provide a clock signal for the receiving end CPU 21.
[0037] After the receiving end 2 obtains the data, the data is transmitted to the fourth input interface 41 of the USBHUB module 4 through the second output interface 212. After the USBHUB module 4 obtains the data, the obtained data is transmitted to the computer input interface 61 of the computer end through the output computer interface 42 in the USBHUB module 4. In addition, the USBHUB module 4 may include an input USB disk interface, and the input USB disk interface may be a special-shaped USB disk docking interface, so that the USBHUB module 4 can transmit the data obtained by the special-shaped USB disk to the computer end through the output USB disk interface 63.
[0038] In addition, the USBHUB module 4 is provided with a third VCC pin 43 and a third ground pin 44, and the power group interface of the computer interface 6 is provided with a fourth VCC pin 621 and a fourth ground pin 622, and the third VCC pin 43 is connected to the fourth VCC pin 621, and the third ground pin 44 is connected to the fourth ground pin 622, so that the computer end provides power to the USBHUB module 4. In addition, the fourth VCC pin 621 and the fourth ground pin 622 are also connected to the first power module 12 and the second power module 22, thereby providing power to the sending end 1 and the receiving end 2.
[0039] When the one-way import device freezes and cannot be transferred during the transmission process or a reset and repair function needs to be performed at the same time, the existing solution requires the one-way import device to be unpacked or the PC to be restarted. Figure 2As shown, since the repair switch 5 involved in the present application is provided with a switch button 51, two metal sheets 52 are fixed at the bottom of the switch button 51, and a group of reset interfaces 53 are provided under each metal sheet 52, when the switch button 51 is pressed, the two metal sheets 52 are respectively connected to the corresponding reset interfaces 53, and when the switch button 51 is released, a mechanical trigger action is performed under the action of the spring inside the button to generate a trigger signal that isolates two physical circuits from each other, and the trigger signal is transmitted to the transmitting end 1 through the first reset pin 113 and to the receiving end 2 through the second reset pin 213, thereby realizing that the two parts of the equipment can be reset and repaired at the same time by pressing the repair switch 5, without removing the shell or restarting the PC.
