Description

Technical Field

[0001] This invention relates to the field of recording and printing technology, and in particular to a method for transmitting data from a network device and a method for receiving data from a network device. Background Technology

[0002] Data transfer under physically isolated conditions is typically achieved using two optical drive groups with different security levels and an automated disc transfer device, often called a transfer machine. A transfer machine is an integrated electromechanical device. The automatic disc transfer mechanism of the transfer machine is usually controlled by a high-security network, enabling the loading and unloading of optical discs between two physically isolated optical drives.

[0003] However, the above data transfer method has obvious shortcomings for more demanding network edge data transmission. For example, since the automatic disk transfer device needs to load and unload between two physically isolated optical drives, there is a risk of data leakage. Its security is not sufficient for more demanding network edge data transmission. Summary of the Invention

[0004] In particular, one object of the present invention is to provide a data transmission method for a network device to improve the security of data transmission between different networks.

[0005] A further objective of this invention is to achieve complete physical isolation between different networks, preventing any signal overlap.

[0006] Specifically, the present invention provides a data transmission method for a transmitting network device, the transmitting network device including a first server, a CD / DVD burner electrically connected to the first server, and a first robotic arm assembly unconnected to the first server. The first robotic arm assembly includes a first controller, a first through-beam sensor group electrically connected to the first controller, and a first robotic arm controlled by the first controller. The data transmission method is applied to the first controller and includes the following steps:

[0007] When the first through-beam sensor group detects that the first tray of the optical drive is open and that the first tray contains an optical disc, the first robotic arm is controlled to move to the location of the optical disc, grab the optical disc, and transport the optical disc to a transmission device capable of transporting the optical disc to a receiving network device.

[0008] Optionally, the transmitting network device further includes a blank optical disc tray storing a plurality of blank optical discs, and the data transmission method further includes the following steps:

[0009] When the first through-beam sensor group detects that the first tray of the optical drive is open and there is no optical disc in the first tray, the first robotic arm is controlled to move to the location of the blank optical disc compartment, grab the blank optical disc, and transport the blank optical disc to the first tray of the optical drive.

[0010] Optionally, the transmitting network device further includes an output slide plate tilted toward the transmitting device, and the step of grabbing the optical disc and transporting the optical disc to the transmitting device capable of transporting the optical disc to the receiving network device is to grab the optical disc and transport the optical disc above the output slide plate, and then release the optical disc to allow the optical disc to fall into the output slide plate, thereby allowing the optical disc to slide along the output slide plate onto the transmitting device.

[0011] Specifically, the present invention also provides a data transmission method for a transmitting network device, the transmitting network device comprising a first server, a plurality of optical drives electrically connected to the first server, and a first robotic arm assembly unconnected to the first server. Each optical drive has a first sensor detection group for detecting whether the optical drive is in a closed state and whether an optical disc is present in the closed state. The first robotic arm assembly comprises a first controller, a first through-beam sensor group electrically connected to the first controller, and a first robotic arm controlled by the first controller. The data transmission method is applied to the first server and includes the following steps:

[0012] When the first sensor detection group detects that the optical drive is in a closed state and contains an optical disc, and that no burning program has been executed, the burning program is executed to burn the blank optical disc in the optical drive.

[0013] After the burning program is completed, the first tray carrying the burned disc is ejected, so that the first tray of the burning optical drive is in an open state. This allows the first through-beam sensor group to detect that the first tray is in an open state and that the first tray carries the burned disc. Consequently, the first controller controls the first robotic arm to grab the burned disc and transport it to a transmission device that can transport the burned disc to a receiving network device.

[0014] Optionally, the first server includes a first sensor for detecting whether there is an optical disc on the first tray of the open optical drive, and the data transmission method further includes the following steps:

[0015] When the first sensor detects that there is an optical disc on the first tray of the open optical drive and that no burning program has been executed, the first tray of the optical drive is controlled to close.

[0016] Specifically, the present invention also provides a method for receiving data transmission from a network device, the network device comprising a second server, a read-only optical drive electrically connected to the second server, and a second robotic arm assembly having no connection to the second server. The second robotic arm assembly comprises a second controller, a second through-beam sensor group electrically connected to the second controller, and a second robotic arm controlled by the second controller. The data transmission method is applied to the second controller and includes the following steps:

[0017] When the second photoelectric sensor group detects that the second tray of the read-only optical drive is open and no optical disc is loaded in the second tray, the second robotic arm is controlled to grab the optical disc transmitted by the sending network device through the transmission device in the aforementioned data transmission method, and place the optical disc in the second tray.

[0018] Optionally, the receiving network device further includes a waste disk storage area, and the data transmission method further includes the following steps:

[0019] When the second photoelectric sensor group detects that the second tray of the read-only optical drive is in the open state and that the second tray contains an optical disc, the second robotic arm is controlled to grab the optical disc and transport it to the waste disc compartment.

[0020] Optionally, the receiving network device further includes an input slide tilted toward the read-only optical drive and connected to the transmission device, and a storage tray located below the output end of the input slide. The step of controlling the second robotic arm to grasp the optical disc transmitted by the sending network device through the transmission device in the aforementioned data transmission method is as follows:

[0021] The second robotic arm is controlled to grab an optical disc that has been slid into the storage compartment by the input slide plate.

[0022] Specifically, the present invention also provides a data transmission method for receiving a network device, the network device comprising a second server, a plurality of read-only optical drives electrically connected to the second server, and a second robotic arm assembly unconnected to the second server. Each read-only optical drive contains a second sensor group for detecting whether the read-only optical drive is in a closed state and whether an optical disc is present in the closed state. The second robotic arm assembly comprises a second controller, a second through-beam sensor group electrically connected to the second controller, and a second robotic arm controlled by the second controller. The data transmission method is applied to the second server and includes the following steps:

[0023] When the second sensor detection group detects that the second tray of the read-only optical drive is in a closed state and that there is an optical disc in the second tray, and no reading program is executed, the reading program is executed to read the optical disc in the read-only optical drive;

[0024] After the reading program is completed, the second tray carrying the read disc is ejected so that the second tray of the read-only optical drive is in an open state. This allows the second through-beam sensor group to detect that the second tray is in an open state and that the second tray carries the read disc. Consequently, the second controller controls the second robotic arm to grab the read disc and transport it to the waste disc compartment.

[0025] Optionally, the second server includes a second sensor for detecting whether there is an optical disc on the second tray of the open optical drive, and the data transmission method further includes the following steps:

[0026] When the second sensor detects that there is an optical disc on the second tray of the open optical drive and that the reading program has not been executed, the second tray of the optical drive is controlled to close.

[0027] According to the embodiment of the present invention, since the first server and the first robotic arm assembly in the transmitting network device have no connection (including physical connection, electrical connection, and signal connection), the first controller in the first robotic arm assembly controls the movement of the first robotic arm based on the information detected by the first through-beam sensor group. The first server is only connected to the optical drive and can control the movement of the optical drive. When the first through-beam sensor group detects that the first tray of the optical drive is open and that the first tray contains an optical disc, it controls the first robotic arm to move to the location of the optical disc, pick up the optical disc, and transport it to the transmission device that can transport the optical disc to the receiving network device. This avoids the possibility of the first server intruding and controlling the first robotic arm assembly when connecting to external data, thereby improving data security.

[0028] Furthermore, the first server and the first robotic arm assembly are not connected in any way; the server's control over the CD / DVD burner is determined based on the detection results of the first sensor detection group. Therefore, the first server and the first robotic arm assembly are independent of each other, which avoids the possibility of the first server unauthorizing control of the first robotic arm assembly when connected to external data, thereby improving data security.

[0029] Furthermore, a separate robotic arm component, namely a second robotic arm component, is also configured in the receiving network device, allowing it to independently receive optical discs transmitted by the transmission device. In other words, both the sending and receiving network devices have their own independent robotic arm components. The first robotic arm component moves only within the sending network device and does not move between the sending and receiving network devices; similarly, the second robotic arm component also moves only within the receiving network device and does not move between the sending and receiving network devices. Moreover, in this embodiment, there is no connection between the second robotic arm component and the second server, thereby avoiding data leakage issues on the second server side and further improving the security of data transmission.

[0030] Furthermore, the second server and the second robotic arm assembly are not connected in any way; the server's control over the read-only optical drive is determined based on the detection results of the second sensor detection group. Therefore, the second server and the second robotic arm assembly are independent of each other, which avoids the possibility of the second server unauthorizing control of the second robotic arm assembly when it connects to external data, thereby improving data security.

[0043] Figure 1 A schematic flowchart of a data transmission method for a transmitting network device according to an embodiment of the present invention is shown. Figure 2 A partial schematic perspective view of a physically isolated unidirectional data transmission device according to an embodiment of the present invention is shown. Figure 3 A schematic structural diagram of a physically isolated unidirectional data transmission device according to an embodiment of the present invention is shown. Figure 2 and Figure 3As shown, the unidirectional data transmission device includes a transmitting network device, a receiving network device, and a transmission device suspended between the transmitting network device and the receiving network device. The transmitting network device includes a first server, a CD-ROM drive electrically connected to the first server, and a first robotic arm assembly unconnected to the first server. The first robotic arm assembly includes a first controller, a first through-beam sensor group electrically connected to the first controller, and a first robotic arm controlled by the first controller. The data transmission method is applied to the first controller. Figure 1 As shown, the data transmission method of the transmitting network device includes:

[0044] In step S110, when the first pair of photoelectric sensor groups detects that the first tray of the CD burner is open and that the first tray contains a CD, the first robotic arm is controlled to move to the location of the CD, grab the CD, and transport the CD to a transmission device that can transport the CD to the receiving network device.

[0045] According to the embodiment of the present invention, since the first server and the first robotic arm assembly in the transmitting network device have no connection (including physical connection, electrical connection, and signal connection), the first controller in the first robotic arm assembly controls the movement of the first robotic arm based on the information detected by the first through-beam sensor group. The first server is only connected to the optical drive and can control the movement of the optical drive. When the first through-beam sensor group detects that the first tray of the optical drive is open and that the first tray contains an optical disc, it controls the first robotic arm to move to the location of the optical disc, pick up the optical disc, and transport it to the transmission device that can transport the optical disc to the receiving network device. This avoids the possibility of the first server intruding and controlling the first robotic arm assembly when connecting to external data, thereby improving data security.

[0046] Figure 4 A schematic flowchart of a data transmission method of a transmitting network device according to another embodiment of the present invention is shown. The optical drive of the transmitting network device has a first sensor detection group for detecting whether the optical drive is in a closed state and whether an optical disc is present in the optical drive when it is closed. Figure 4 The data transmission method shown is applied in the first server, and the data transmission method includes:

[0047] Step S210: When the first sensor detection group detects that the CD burner is in a closed state and contains a CD, and has not executed a burning program, the burning program is executed to burn the blank CD in the CD burner.

[0048] Step S220: After the burning program is completed, the first tray carrying the burned disc is ejected so that the first tray of the burning optical drive is in an open state. This allows the first through-beam sensor group to detect that the first tray is in an open state and that the first tray carries the burned disc. This causes the first controller to control the first robotic arm to grab the burned disc and transport it to the transmission device that can transport the burned disc to the receiving network device.

[0049] According to the embodiment of the present invention, the first server and the first robotic arm assembly are not connected to each other, and the server's control over the optical drive is determined based on the detection results of the first sensor detection group. Therefore, the first server and the first robotic arm assembly are independent of each other, which avoids the possibility of the first server intruding and controlling the first robotic arm assembly when it connects to external data, thereby improving data security.

[0050] Figure 5 A schematic flowchart illustrating a method for receiving data transmission from a network device according to an embodiment of the present invention is shown. Figure 2 and Figure 3 As shown, the receiving network device includes a second server, a read-only optical drive electrically connected to the second server, and a second robotic arm assembly unconnected to the second server. The second robotic arm assembly includes a second controller, a second through-beam sensor group electrically connected to the second controller, and a second robotic arm controlled by the second controller. The data transmission method is applied to the second controller, such as... Figure 5 As shown, the output transmission method includes:

[0051] In step S310, when the second through-beam sensor group detects that the second tray of the read-only optical drive is open and no optical disc is loaded in the second tray, the second robotic arm is controlled to grab the optical disc transmitted by the sending network device through the transmission device and place the optical disc in the second tray.

[0052] According to the embodiment of the present invention, a separate robotic arm component, namely a second robotic arm component, is also provided in the receiving network device, thereby enabling the independent reception of optical discs transmitted by the transmission device. That is, the sending network device and the receiving network each have their own independent robotic arm component. The first robotic arm component moves only within the sending network device and does not move between the sending and receiving network devices. Similarly, the second robotic arm component also moves only within the receiving network device and does not move between the receiving and sending network devices. Furthermore, in this embodiment, there is no connection between the second robotic arm component and the second server, thereby avoiding data leakage issues on the second server side and further improving the security of data transmission.

[0053] Figure 6A schematic flowchart illustrating a method for receiving data transmission from a network device according to another embodiment of the present invention is shown. Figure 2 and Figure 3 As shown, the read-only optical drive of the receiving network device has a second sensor detection group for detecting whether the read-only optical drive is in a closed state and whether there is an optical disc in the read-only optical drive when it is in a closed state. The data transmission method of the receiving network device is applied to the second server, such as... Figure 6 As shown, the data transmission method of the receiving network device includes:

[0054] Step S410: When the second sensor detection group detects that the second tray of the read-only optical drive is in a closed state and there is an optical disc in the second tray, and no reading program is executed, the reading program is executed to read the optical disc in the read-only optical drive.

[0055] In step S420, after the reading program is completed, the second tray carrying the read disc is ejected so that the second tray of the read-only optical drive is in an open state. This allows the second through-beam sensor group to detect that the second tray is in an open state and that the second tray carries the read disc. Consequently, the second controller controls the second robotic arm to grab the read disc and transport it to the waste disc compartment.

[0056] According to the embodiment of the present invention, the second server and the second robotic arm assembly are not connected to each other, and the control of the read-only optical drive is determined based on the detection results of the second sensor detection group. Therefore, the second server and the second robotic arm assembly are independent of each other, which can avoid the possibility of the second server intruding and controlling the second robotic arm assembly when it connects to external data, thereby improving data security.

[0057] The following detailed description uses specific embodiments.

[0058] Example 1:

[0059] The transmitting network device 1 is used to burn data onto a blank optical disc, and the receiving network device 2 is used to read the data from the burned optical disc by the transmitting network device 1. The receiving network device 2 and the transmitting network device 1 are independent of each other and form a physically isolated space without any signal or physical connection. The spatial positions of the transmitting network device 1 and the receiving network device 2 can be set as needed, but these two network devices must not have any signal or physical connection relationship. For example, these two network devices can be placed in two different buildings, or on different floors of the same building. To achieve complete physical isolation during data transmission, this application designs a completely contactless unidirectional data transmission device, thereby achieving complete physical isolation and avoiding any signal or physical contact during transmission. The transmitting device 3 of this unidirectional data transmission device is suspended between the transmitting network device 1 and the receiving network device 2, used to receive the burned optical disc output by the transmitting network device 1 without contact and to transmit the burned optical disc to the receiving network device 2 without contact.

[0060] like Figure 2 and Figure 3 As shown, the transmitting network device 1 generally includes a plurality of CD / DVD burners 11 arranged in an array, such as vertically, horizontally, or in other directions. The receiving network device 2 generally includes a plurality of read-only optical drives 21 arranged in an array, such as vertically, horizontally, or in other directions. In a preferred embodiment, the arrangement of the plurality of CD / DVD burners 11 is consistent with the arrangement of the plurality of read-only optical drives 21. For example, if the plurality of CD / DVD burners 11 are arranged in a vertical array, then the plurality of read-only optical drives 21 are also arranged in a vertical array; if the plurality of CD / DVD burners 11 are arranged in a horizontal array, then the plurality of read-only optical drives 21 are also arranged in a horizontal array. The following description uses a scheme in which both the plurality of CD / DVD burners 11 and the plurality of read-only optical drives 21 are arranged in a vertical array as an example, and the plurality of vertically arrayed CD / DVD burners 11 and the plurality of vertically arrayed read-only optical drives 21 are stacked together in a layered arrangement. However, the scope of protection of the present invention is not limited thereto.

[0061] The transmitting network device 1 may further include a blank optical disc tray 15, which stores multiple blank optical discs. A first robotic arm 121 can move to the location of the blank optical disc tray 15 and grab a blank optical disc. The first controller is also configured to control the first robotic arm 121 to grab a blank optical disc from the blank optical disc tray 15 and move the blank optical disc into the optical disc burner 11 when the first through-beam sensor group detects that the optical drive 11 has ejected and the first tray 111 is not carrying an optical disc.

[0062] Therefore, the data transmission method applied to the first controller further includes the following steps: when the first through-beam sensor group detects that the first tray 111 of the optical drive 11 is in an open state and there is no optical disc in the first tray 111, the first robotic arm 121 is controlled to move to the location of the blank optical disc compartment 15, grab the blank optical disc and transport the blank optical disc to the first tray 111 of the optical drive.

[0063] The first through-beam sensor group is used to detect whether the CD / DVD burner 11 has ejected and whether the first tray 111 of the CD / DVD burner 11 contains an optical disc. The first controller is stationary, the first robotic arm 121 is movable horizontally and vertically, the first through-beam sensor group is fixedly mounted at the first controller, and the position of the first through-beam sensor group can detect whether the CD / DVD burner 11 has ejected, and can also detect whether the first tray 111 of the ejected CD / DVD burner 11 contains an optical disc. The first through-beam sensor group may include multiple through-beam sensors, wherein one or more through-beam sensors are used to detect whether the first tray 111 of the CD / DVD burner 11 has ejected, and another or more through-beam sensors are used to detect whether the first tray 111 contains an optical disc.

[0064] The transmission network device 1 also includes at least one output slide plate 13. Preferably, it may include multiple output slide plates 13, thus enabling the synchronous output of multiple optical discs. The multiple output slide plates 13 are arranged in a manner consistent with the arrangement of the multiple optical recordable drives 11. For example, when the multiple optical recordable drives 11 are arranged vertically, the multiple output slide plates 13 are arranged vertically and spaced apart; when the multiple optical recordable drives 11 are arranged horizontally, the multiple output slide plates 13 are arranged horizontally and spaced apart. Furthermore, the transmission network device 1 includes at least one first output port 14. The number and arrangement of the first output ports 14 are generally consistent with the number and arrangement of the output slide plates 13, and the first output ports 14 are located at the ends of the output slide plates 13, so that when an optical disc slides from the output slide plate 13 to the transmission device 3, it must pass through the first output port 14 before sliding onto the transmission device 3. The output slide plate 13 is inclined towards the transmission device 3 to receive the optical disc transported by the first robotic arm 121 before the first robotic arm 121 transports the optical disc to the transmission device 3, and to allow the optical disc to slide onto the transmission device 3. There is no physical contact between the output slide plate 13 and the transmission device 3. The optical disc on the output slide plate 13 slides down onto the transmission device 3 by its own gravity. This setting can avoid the possible data leakage problem caused by the contact between the output slide plate 13 and the transmission device 3, and achieve zero leakage in the data output transmission process.

[0065] The conveying device 3 includes at least one conveyor belt 31. Preferably, it may include multiple conveyor belts 31, and the number of conveyor belts 31 may match the number of output slides 13, with one output slide 13 corresponding to one conveyor belt 31. The conveyor belt 31 may be horizontal or inclined at a certain angle, as long as it ensures that the optical disc will not slide on it. Preferably, the conveyor belt 31 is horizontal. The first output port 14 of the transmitting network device 1 is located higher than the input end of the conveyor belt 31 of the conveying device 3. After the optical disc slides out from the first output port 14, it falls to the input end of the conveyor belt 31. To avoid damage to the optical disc during its fall, the height difference between the location of the first output port 14 and the location of the input end of the conveyor belt 31 is within a reasonable range, ensuring that the optical disc will not break during its fall. Furthermore, to prevent the optical disc from flipping or changing position during its fall, the conveying device 3 can be housed in a standard industrial control cabinet. The transmitting network device 1 and the receiving network device 2 can also be housed separately in standard industrial control cabinets.

[0066] In step S110, when the first through-beam sensor group detects that the first tray 111 of the CD burner 11 is open and contains a CD, the first robotic arm 121 is controlled to move to the location of the CD, grasp the CD, and transport it above the output slide plate 13. The CD is then released to fall into the output slide plate 13, allowing it to slide along the output slide plate 13 onto the conveyor 3. During this process, there is no contact between the first robotic arm 121 and the output slide plate 13, thus preventing data leakage. Furthermore, there is no contact between the output slide plate 13 and the conveyor belt 31, therefore, there is no data leakage during the process of sliding from the output slide plate 13 onto the conveyor belt 31.

[0067] In this embodiment, the transmitting network device and its data transmission method adopt the method described above. The receiving network device can be a mechanism capable of receiving the optical disc transmitted by the transmitting device 3 and transporting the optical disc to the read-only optical drive 21 within the receiving network device. It is not required that there is no connection between this mechanism and the second server. Since the receiving network device and the transmitting network device are independent of each other and form a physically isolated space without signal or physical connection, and the transmitting device 3 of the unidirectional data transmission device is suspended between the transmitting network device and the receiving network device, it is used to receive the recorded optical disc output by the transmitting network device without contact and transmit the recorded optical disc to the receiving network device without contact. This avoids data leakage on the transmitting network device side.

[0068] Example 2:

[0069] The difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 provides an embodiment in which the first server and the first robotic arm assembly are completely unconnected. In this embodiment, each CD / DVD drive 11 of the transmitting network device 1 is equipped with a first internal detection unit (not shown in the figure) capable of detecting whether it contains an optical disc. This first internal detection unit is electrically connected to the first server. A first sensor (not shown in the figure) is provided on the outside of the CD / DVD drive 11 to detect whether an optical disc is present on the first tray 111 of the ejected CD / DVD drive 11. This first sensor is also electrically connected to the first server. The data transmission method applied to the first server further includes the following steps: when the first sensor detects that an optical disc is present on the first tray 111 of the CD / DVD drive 11 in the open state and no burning program has been executed, the first tray 111 of the CD / DVD drive 11 is closed to send the optical disc into the CD / DVD drive 11. It can be understood that the optical disc at this time is a blank optical disc.

[0070] In step S210, the first sensor detection group includes at least one first internal detection unit. The data transmission method in step S210 is applied to the first server, specifically: when the first internal detection unit detects that the optical disc burner 11 contains an optical disc and that the optical disc burner 11 has already executed a burning program on the optical disc, the first server controls the first tray 111 of the optical disc burner 11 to eject. It can be understood that the optical disc at this time is a burned optical disc. When the first internal detection unit detects that the optical disc burner 11 is in a closed state and contains an optical disc, and that the optical disc burner 11 has not executed a burning program on the optical disc, the burning program is executed to burn a blank optical disc in the optical disc burner. After the burning program is completed, the first tray 111 carrying the burned disc is ejected, so that the first tray 111 of the optical drive is in an open state. This allows the first through-beam sensor group to detect that the first tray 111 is in an open state and that the first tray 111 carries the burned disc. This causes the first controller to control the first robotic arm 121 to grab the burned disc and transport it to the transmission device 3, which can transport the burned disc to the receiving network device.

[0071] In other words, the first server determines when to open and close the first tray 111 based on information detected by the first internal detection unit and the first sensor. Meanwhile, the first controller in the first robotic arm assembly determines when to control the first robotic arm 121 based on information detected by the first through-beam sensor group. Therefore, the first server and the first robotic arm assembly can transmit data without any connection whatsoever.

[0072] Example 3:

[0073] The difference between this embodiment and embodiment one or embodiment two is that in this embodiment, the second server is electrically connected to the read-only optical drive 21 and is used to control the ejection and closing of the read-only optical drive 21. Each read-only optical drive 21 has a second internal detection unit (not shown in the figure) capable of detecting whether it contains a disc. This second internal detection unit is electrically connected to the second server. When the second internal detection unit detects that the read-only optical drive 21 contains a disc and that the read-only optical drive 21 has already executed a reading program on the disc, the second server controls the second tray 211 of the read-only optical drive 21 to eject. It can be understood that the disc at this time is a read disc. A second sensor (not shown in the figure) is provided on the outside of the read-only optical drive 21 to detect whether there is a disc on the second tray 211 of the ejected read-only optical drive 21.

[0074] The second controller is stationary, while the second robotic arm 221 is movable horizontally and vertically. The second through-beam sensor group is fixedly mounted on the second controller, and its position allows it to detect whether the optical drive 21 has ejected, and whether a disc is present in the second tray 211 of the ejected optical drive 21. The second through-beam sensor group may include multiple through-beam sensors, one or more of which detect whether the second tray 211 of the optical drive 21 has ejected, and another or more sensors detect whether a disc is present in the second tray 211. In step S310, the second controller in the second robotic arm assembly controls the movement of the second robotic arm 221 based on the state of the optical drive 21 detected by the second through-beam sensor group.

[0075] The second server is electrically connected to the read-only optical drive 21 and is used to control the ejection and closing of the read-only optical drive 21. Each read-only optical drive 21 has an internal detection unit (not shown in the figure) capable of detecting whether it contains a disc. In step S410, the second internal detection unit is electrically connected to the second server. When the second internal detection unit detects that the read-only optical drive 21 contains a disc and that the read-only optical drive 21 has already executed a reading program on the disc, the second server controls the ejection of the second tray 211 of the read-only optical drive 21. It can be understood that the disc at this time is a read disc. A second sensor (not shown in the figure) is provided on the outside of the read-only optical drive 21 to detect whether there is a disc on the second tray 211 of the ejected read-only optical drive 21. The second sensor is also electrically connected to the second server. When the second sensor detects that there is a disc on the second tray 211 of the ejected optical drive 21 and that the optical drive 21 has not performed a reading program on the disc, the second server controls the second tray 211 of the optical drive 21 to close, so as to send the disc into the interior of the optical drive 21 for reading. It can be understood that the disc is blank at this time.

[0076] The data transmission method applied to the second server further includes the following steps: when the second sensor detects that there is an optical disc on the second tray of the open optical drive and no reading program has been executed, the second tray of the optical drive is controlled to close.

[0077] The receiving network device 2 may also include a waste disc tray 26, which stores multiple waste optical discs (damaged or fully read discs, etc.). The second robotic arm 221 can move to the location of the waste disc tray 26 and drop the waste optical discs into it. The data transmission method applied to the second controller further includes the following steps: when the second through-beam sensor group detects that the read-only optical drive 21 has ejected and the second tray 211 is carrying an optical disc, the second robotic arm 221 is controlled to grab the optical disc and transport it to the waste disc tray 26. It is understood that the optical disc grabbed at this time is a fully read disc.

[0078] The receiving network device 2 also includes at least one input slide 23. Preferably, it may include multiple input slides 23, thus enabling the synchronous input of multiple optical discs. The multiple input slides 23 are arranged in a manner consistent with the arrangement of the multiple optical drives 21. For example, when the multiple optical drives 21 are arranged vertically, the multiple input slides 23 are arranged vertically and spaced apart; when the multiple optical drives 21 are arranged horizontally, the multiple input slides 23 are arranged horizontally and spaced apart. Furthermore, the receiving network device 2 includes at least one first input port 24. The number and arrangement of the first input ports 24 are generally consistent with the number and arrangement of the input slides 23, and the first input port 24 is located at the front end of the input slide 23, so that the optical discs transmitted by the conveyor 3 first pass through the first input port 24 before entering the input slide 23. The output slide 13, the first input port 24, the input slide 23, the first output port 14, and the conveyor belt 31 correspond one-to-one, and they form a group as a whole. The unidirectional data transmission device may include multiple such groups of structures. The first input port 24, conveyor belt 31, and first output port 14 of the same group are located at approximately the same height. Although the height of the first output port 14 is slightly higher than the height of the input end of the conveyor belt 31, the overall height difference is not significant and can be considered essentially zero. The input slide 23 is tilted downwards and positioned below the corresponding position of the conveyor belt 31, and is used to receive the optical disc transmitted by the transmission device 3. The position of the input slide 23 can also be set to be approximately flush with the position of the conveyor belt 31. There is no physical contact between the input slide 23 and the transmission device 3. This arrangement avoids potential data leakage problems caused by contact between the input slide 23 and the transmission device 3, achieving zero leakage during data output transmission.

[0079] At the end of each input slide 23 (the concept corresponding to the front end, i.e., the rear end), there is also a disc storage compartment 25. This disc storage compartment 25 is located below the output end of the corresponding input slide 23 and is used to receive the optical discs that slide out of the input slide 23. It can be understood that the optical discs on the input slide 23 can slide into the disc storage compartment 25 under their own gravity.

[0080] In step S310, the second robotic arm 221 is controlled to grab the optical disc transmitted by the sending network device through the transmission device 3 and place the optical disc in the second tray 211. Specifically, the second robotic arm 221 is controlled to grab the optical disc that has slid into the storage tray 25 from the storage tray 25 by the input slide plate 23.

[0081] According to the embodiments of the present invention, the transmitting network device 1, the receiving network device 2, and the transmitting device 3 are all independent of each other, with no physical, signal, or electrical connections. This greatly ensures the security of the data transfer process. Not only are the transmitting network device 1, the receiving network device 2, and the transmitting device 3 independent, but the first server and the first robotic arm component 12 in the transmitting network device 1 are also independent, as are the second server and the second robotic arm component 22 in the receiving network device 2. This further enhances the security of the data transfer process. Furthermore, even the first robotic arm 121 and the first output slide plate 13 are independent, as are the second robotic arm 221 and the first input slide plate 23. Therefore, the present invention truly achieves zero data leakage during the data transfer process, resulting in extremely high data security with no risk of leakage.

[0082] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the common principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
