Currently, optical discs are commonly used as data carriers for importing and exporting data between internal and external networks.

Furthermore, the optical discs used for importing and exporting data require regular cleaning, which also increases the risk of data leakage.

Detailed Implementation

[0019] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0020] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably. Expressions such as "first," "second," etc., are merely used to distinguish technical terms.

[0021] This invention provides a physically isolated data transmission system, such as... Figures 1-6As shown, the physically isolated data transmission system includes a first control system (e.g., automated control system 1), a second control system (e.g., automated control system 2), and a storage medium transfer device. The storage medium transfer device includes a frame 4 and a drive module 5, a guide rail, a media transfer platform (e.g., a USB flash drive transfer platform 3), a first connection module (e.g., a USB probe board 1), and a second connection module (e.g., a USB probe board 2) mounted on the frame 4. The media transfer platform 3 is mounted on the guide rail and is provided with interconnected media interfaces (e.g., a USB interface 34) and media connection structures. The media transfer platform is connected to the drive module 5. The media interface is used to connect the storage medium 6. Both the first connection module and the second connection module are provided with data interfaces (e.g., a USB data interface 12) for data transmission, and the two data interfaces are used to connect to a first computer and a second computer, respectively. During data transmission between the first computer and the second computer, the first control system moves the medium transfer platform to a first position on the guide rail and establishes a connection between the first connection module and the medium connection structure to mount the storage medium onto the first computer, thereby copying the data to be transmitted from the first computer to the storage medium. After the copying is completed, the first connection module is disconnected from the medium connection structure, and the medium transfer platform is moved to a second position and a docking signal is sent to the second control system. Upon detecting the docking signal, the second control system, at a second position, drives the second connection module to establish a connection with the media connection structure, thereby mounting the storage medium onto the second computer and copying the data from the storage medium to the second computer. This completes data transmission between the physically isolated first and second computers. The first and second control systems can be located in mutually isolated physical spaces.

[0022] In this embodiment of the invention, independent control systems (first and second control systems) for internal and external networks respectively use mechanical control to mount the storage medium onto computers on independent internal and external networks, thereby enabling secure data transmission between internal and external networks, improving the security of data transmission between internal and external networks, enhancing data security, and reducing human error.

[0023] In this embodiment of the invention, the storage medium transfer device is driven by two independent control systems. The two control systems do not communicate directly with each other, but transmit control signals through physically isolated signal transmissions. This enables the storage medium to be mounted on internal and external network computers respectively, effectively ensuring the isolation between internal and external networks and further providing data transmission security for internal and external network systems.

[0024] In this embodiment of the invention, the storage medium transfer device, through a drive module, guide rail, media transfer moving platform, first connection module, and second connection module, eliminates the need for plugging and unplugging the storage medium during data transmission between physically isolated internal and external network computers, thus extending the lifespan of the storage medium. Furthermore, in some embodiments, a storage medium pluggable protection structure can be set at the media interface to restrict the removal of the storage medium. This effectively reduces data leakage through external storage media during data transmission between internal and external networks.

[0025] The embodiments of the present invention can prevent two computers from using storage media interchangeably, avoid illegal data exchange between the two computers, and meet industry regulations on data security.

[0026] The media interface can be a USB interface or a solid-state drive (SSD) interface; the USB interface type can be any one of Type-A, Type-B, Mini-USB, Micro-USB, and Type-C; the SSD interface type can be any one of SATA, PCIe, M.2, and NVMe; the media interface and media connection structure establish a connection relationship based on the corresponding interface type protocol.

[0027] In some embodiments, both the first connection module (e.g., USB probe board 1) and the second connection module (e.g., USB probe board 2) are provided with USB probe structures, each USB probe structure having a plurality of USB probes 15; the media connection structure is provided with USB connection contacts 32 that match the USB probes. When the USB probes are connected to the USB connection contacts, the first or second connection module corresponding to the USB probe structure establishes a connection relationship with the media connection structure; when the USB probes are separated from the USB connection contacts, the first or second connection module corresponding to the USB probe structure disconnects from the media connection structure.

[0028] In this embodiment, the probe and contact not only enable the USB mounting function, but also reduce the need for plugging and unplugging the USB flash drive during data transmission, thereby extending the lifespan of the USB flash drive.

[0029] In some embodiments, the first connection module is further provided with a first connection detection probe structure (e.g., external network detection probe 14) and a first detection interface (e.g., external network detection interface 11), and the second connection module is further provided with a second connection detection probe structure and a second detection interface, the first detection interface and the second detection interface being used to connect to the first computer and the second computer respectively; the medium connection structure is further provided with a connection detection contact structure; The first control system is also used to establish an electrical connection between the USB probe structure of the first connection module and the first computer when it is detected that the first connection detection probe structure and the connection detection contact structure are in a connection relationship, so as to enable the storage medium to be mounted on the first computer. The second control system is also used to establish an electrical connection between the USB probe structure of the second connection module and the second computer when the second connection detection probe structure and the connection detection contact structure are detected to be in a connection relationship, so as to enable the storage medium to be mounted on the second computer.

[0030] In this embodiment, a connection detection probe structure and a detection interface are set in the first connection module and the second connection module to realize docking detection. Once docking detection is detected, an electrical connection is established between the USB probe structure and the corresponding computer, thus avoiding problems in the connection between the USB probe structure and the corresponding USB probe, which could affect the hardware device.

[0031] The first connection detection probe structure and the second connection detection probe structure (e.g., detection probe 14 or 16) are each provided with multiple detection probes, and the connection detection contact structure (e.g., detection contact 31 or 33) is provided with detection contacts that match the multiple detection probes. The physically isolated data transmission system also includes a first statistics module and a second statistics module. The first statistics module is used to count the first connection count between the first connection detection probe structure and the connection detection contact, and the second statistics module is used to count the second connection count between the second connection detection probe structure and the connection detection contact. When the count of the first connection count or the count of the second connection count reaches a preset threshold, the system prompts the user to replace the USB probe structure and the USB adapter structure.

[0032] In some implementations, the media transfer mobile platform is also equipped with a position encoder to achieve full closed-loop control and ensure the alignment of the probe and the contact.

[0033] In some implementations, the first control system is provided with a first signal terminal (e.g., a signal transmitting terminal and a signal receiving terminal), and the second control system is provided with a second signal terminal (e.g., a signal receiving terminal and a signal transmitting terminal); the first control system and the second control system achieve physically isolated signal transmission through the first signal terminal and the second signal terminal.

[0034] In some implementations, a rewritable storage medium is used as the transfer medium, and a physically isolated signal transmission system is used for command interaction, which effectively improves the security and reliability of data transmission between physically isolated internal and external networks.

[0035] For example, using optocouplers (but not limited to this method), the transmitting end is an infrared emitting diode, and the receiving end is an infrared receiving tube. When transmitting external network status, such as when a USB drive needs to be connected to the internal network, the external network turns the transmitting signal on or off via the signal transmitting end, and the internal network receives the switch signal via the signal receiving end to determine the signal type and execute the specific operation (connection or disconnection, etc.). For instance, docking signal interaction is accomplished using infrared emitting and receiving tubes. The first and second signal ends use multiple sets of infrared emitting and receiving tubes to transmit docking signals, thereby enabling the transmission of multiple simple commands.

[0036] The following describes in detail various implementation methods of embodiments of the present invention, using the USB interface as an example.

[0037] like Figure 1-2 As shown, a physically isolated data transmission system includes a USB flash drive adapter mobile platform, a computer 1, a USB security management module 1, a USB probe board 1, an automated control system 1, a physically isolated signal transmission module, a computer 2, a USB security management module 2, a USB probe board 2, and an automated control system 2.

[0038] In this configuration, computer 1 can optionally connect to USB security management module 1 using USB cable 1, and then connect to USB probe board 1 using USB cable 2. Alternatively, USB cable 1 can be used to directly connect to USB probe board 1. It can also connect to automation control system 1 via USB cable 5 to transmit control commands.

[0039] Computer 2 can optionally be connected to USB security management module 2 via USB cable 3, and then connected to USB probe board 2 via USB cable 4. Alternatively, USB cable 3 can be used to directly connect to USB probe board 2. The automated control system 2 is connected via USB cable 6 to transmit control commands.

[0040] Signal transmission between internal and external networks can be achieved through a computer physical isolation signal transmission module, enabling completely physically isolated signal transmission.

[0041] like Figure 3-4 As shown, USB probe board 1 includes an external network detection interface 11, a USB interface 12, an internal network detection interface 13, an external network detection probe 14, a USB data transmission probe 15, and an internal network detection probe 16. In specific implementation, the internal network detection interface 13 can be left floating. Of course, the internal network detection interface 13 and the internal network detection probe 16 can also be omitted. The USB interface 12 is a female connector, which can be connected to computer 1 via a USB cable to achieve USB data transmission. The structure of USB probe board 2 can be set to be the same as that of USB probe board 1.

[0042] The USB probe board 1 includes two sets of interfaces. One set is used to count the number of times the USB probe board is used, and the other set is connected to the connection detection contact through the external network detection probe 14, which can realize the counting of the number of times the USB flash drive adapter board is used.

[0043] The USB probe board 2 includes two sets of interfaces. One set is used to count the number of times the USB probe board is used, and the other set is connected to the connection detection contact through the intranet detection probe 16, which can realize the counting of the number of times the USB flash drive adapter board is used.

[0044] like Figure 5-6 As shown, the USB flash drive adapter platform 3 can be a USB flash drive adapter board, including an external network detection contact 31, a USB transmission contact 32, an internal network transmission contact 33, and a USB flash drive interface 34. The external network detection contact 31 interfaces with the external network detection probe 14 to count the number of times the USB flash drive adapter board has been used. The internal network detection contact interfaces with the internal network detection probe 16 to count the number of times the USB flash drive adapter board has been used. The USB flash drive interface 34 can connect to a USB flash drive. Two independent storage chips can be added to the USB flash drive adapter platform 3, forming a first and a second statistical module respectively. Alternatively, the first and second statistical modules can be set in the first and second control systems respectively. Adding two independent storage chips for counting the number of times a contact is connected accumulates one count. When the accumulated count reaches the contact's usage limit, a lifespan limit warning is issued, allowing for the estimation of the USB connection contact lifespan of the USB flash drive adapter platform and increasing the maintainability of the device in the later stages.

[0045] Under the control of the automated control system 1, the USB flash drive adapter moving platform can move left and right on the guide rail. The automated control system 1 controls the left and right movement of the USB flash drive adapter moving platform through servo motors, stepper motors, etc., and then achieves full closed-loop control through the position encoder on the USB flash drive adapter moving platform to ensure the alignment of the position of the pins and contacts.

[0046] The USB probe board 1 can move up and down under the control of the automated control system 1. The automated control system 1 controls the up and down movement of the USB probe board 1 through servo motors, stepper motors, etc., to ensure the stability of the contact between the probe and the contact point.

[0047] When it is necessary to connect the USB flash drive on the USB flash drive adapter platform to computer 1 on the external network, computer 1 sends a docking command to the automated control system 1 through the USB interface. The automated control system 1 then controls the USB flash drive adapter platform to move below the USB probe board 1, and then controls the USB probe board 1 to move downwards and connect to the USB connection contact point on the USB flash drive adapter platform, thus realizing the electrical connection between the USB flash drive and computer 1.

[0048] Furthermore, the USB probe board 2 can move up and down under the control of the automated control system 2. The automated control system 2 controls the up and down movement of the USB probe board 2 through servo motors, stepper motors, etc., to ensure the stability of the contact between the probe and the contact point.

[0049] When a USB flash drive on the USB flash drive adapter platform needs to be connected to computer 2 on the external network, computer 1 sends a docking command to the automated control system 1 via the USB interface. The automated control system 1 then controls the USB flash drive adapter platform to move below the USB probe board 1. Next, the automated control system 1 sends a USB flash drive docking signal to the automated control system 2 via the physical isolation signal transmission module. Upon receiving the USB flash drive docking signal, the automated control system 2 controls the USB probe board 2 to move downwards and connect to the USB connection point on the USB flash drive adapter platform, thus establishing an electrical connection between the USB flash drive and computer 2.

[0050] Optionally, to ensure system stability and prevent damage to the USB flash drive, the automated control system 1 and automated control system 2 are equipped with overcurrent protection and short-circuit protection when the USB probe 1 and USB probe 2 make contact with the contacts on the USB flash drive transfer platform. When the probes and contacts make accidental contact, the circuit is cut off in time to ensure that the USB flash drive and circuit board are not damaged.

[0051] When the USB probe board 1 and USB probe board 2 make contact with the contacts on the USB flash drive transfer platform, the automated control system 1 and automated control system 2 respectively identify the usage count storage chip on the USB flash drive transfer platform. When identified, the retry docking mechanism is triggered.

[0052] When the USB probe board 1 and USB probe board 2 make contact with the contacts on the USB flash drive transfer platform, the computer automatically recognizes the USB flash drive mounting. If the USB flash drive mounting fails, it automatically triggers a retry docking and mounting operation, increasing the system's fault tolerance and ensuring the smooth execution of the transfer task.

[0053] In some implementations, USB probe board 1 and USB probe board 2 may optionally include a memory chip for counting the number of times the USB probes are used, enabling estimation of the USB probes' lifespan and increasing the maintainability of the device later. For example, the memory chip for counting the number of times the USB probes are used on USB probe board 1 may be connected to the automation control system 1 only via a data cable. Similarly, the memory chip for counting the number of times the USB probes are used on USB probe 2 may be connected to the automation control system 2 only via a data cable.

[0054] Briefly describe the principle of the data transmission system provided in the embodiments of the present invention.

[0055] like Figure 1-6As shown, USB flash drive 6 is inserted into the USB flash drive interface 34 of the USB flash drive adapter platform 3. The USB flash drive adapter platform 3 is fixed on the guide rail and connected to the synchronous belt of the drive module 5. After establishing a data import task, computer 1 sends a command to connect the USB flash drive to the external network to the automated control system 1 via USB cable 5. After receiving the control command, the automated control system 1 controls the USB flash drive adapter platform to move below the USB probe board 1 via the synchronous belt of the drive device 5. The automated control system 1 then controls the USB probe board 1 to move downwards so that the probes of the USB probe board 1 align with the USB connection contact points, thereby enabling the USB flash drive to be mounted to computer 1. After the USB flash drive is successfully mounted, computer 1 can perform read and write operations on the data on the USB flash drive.

[0056] Furthermore, after computer 1 completes the read / write operations on the USB flash drive, it sends a command to connect the USB flash drive to the intranet via USB cable 5 to the automated control system 1. Upon receiving this command, automated control system 1 first moves the USB flash drive transfer platform below the USB probe board 2, and then sends the intranet USB flash drive mounting command to automated control system 2 via the physical isolation signal transmission module. Upon receiving the USB flash drive mounting command, automated control system 2 controls the USB probe board 2 to move, causing the probes of the USB probe board 2 to connect with the contacts of the USB flash drive transfer platform, thereby mounting the USB flash drive to computer 2. After successful mounting, computer 2 can read and write data from the USB flash drive, thus achieving the purpose of the entire data transfer.
