The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
The invention provides a data ferry machine, which comprises an outer network module 100, an intermediate isolation control module 200 and an inner network module 300 as shown in fig. 1 to 7. The external network module 100 is configured to receive data of an external network system, record the data, and transmit the data to a storage medium storing the data. The intermediate isolation control module 200 is used for screening data security, and transmitting the security data from the external network module 100 to the internal network module 300. The intranet module 300 is used for connecting an intranet system, and the intranet system can obtain data through the intranet module 300.
As shown in fig. 6, the outer network module 100 includes an outer network cartridge 110, an outer network recording optical drive 120, a first transmission component 130, and an intermediate read-only optical drive 140. The outer net drum 110 stores a plurality of first optical discs 10, wherein the first optical discs 10 are storage media capable of storing data, and the outer net drum 110 can sequentially store the first optical discs 10 Zhang Shifang one by one, so that the first optical discs 10 sequentially enter the first transmission assembly 130 for transmission. The outer net drum 110 may have a conventional drum structure, and thus the specific structure of the outer net drum 110 will not be described here.
The structures of the outer network recording optical disc drive 120 and the intermediate read-only optical disc drive 140 are all in the prior art, and the existing optical disc drives capable of recording optical discs and networking can be used as the outer network recording optical disc drive 120 of the present invention, while the existing optical disc drives capable of reading optical discs and networking can be used as the intermediate read-only optical disc drive 140 of the present invention, and the structures of the outer network recording optical disc drive 120 and the intermediate read-only optical disc drive 140 are not described herein.
As shown in fig. 6, the first transmission assembly 130 is disposed between the outer network recording optical disc drive 120 and the intermediate read only optical disc drive 140, and the outlet of the outer network disc cartridge 110 is higher than the first transmission assembly 130, so that the first optical disc 10 removed from the outer network disc cartridge 110 can fall onto the first transmission assembly 130 under the action of gravity. The first transport assembly 130 is capable of bi-directionally transporting the first optical disc 10, i.e. the first transport assembly 130 is capable of moving the first optical disc 10 in a direction approaching the outer disc drive 120, and is also capable of moving the first optical disc 10 in a direction approaching the middle read-only optical disc drive 140.
Specifically, the first conveying assembly 130 includes a carriage, a driving mechanism, and a first access mechanism, a linear conveying mechanism, and a second access mechanism that are disposed at intervals along a horizontal direction, where the driving mechanism, the first access mechanism, the linear conveying mechanism, and the second access mechanism are all disposed on the carriage. The first inlet and outlet mechanism is provided with a first inlet and outlet, and the second inlet and outlet mechanism is provided with a second inlet and outlet.
The first access mechanism and the second access mechanism have the same structure, the first access mechanism is disposed near the outer network recording optical disc drive 120, and the second access mechanism is disposed near the middle read-only optical disc drive 140. Under the drive of the driving mechanism, the first optical disc 10 falling onto the linear conveying mechanism can move to the first in-out mechanism and enter the outer net recording optical drive 120 through a first inlet and outlet on the first in-out mechanism, and after the outer net recording optical drive 120 finishes recording the first optical disc 10, the first optical disc 10 can enter the linear conveying mechanism through the first in-out mechanism again; after that, under the driving of the driving mechanism, the first optical disc 10 located on the linear conveying mechanism can move to the middle read-only optical disc drive 140, and enter the middle read-only optical disc drive 140 through the second inlet and outlet of the second inlet and outlet mechanism, and after the reading of the first optical disc 10 in the middle read-only optical disc drive 140 is completed, the first optical disc 10 can enter the linear conveying mechanism again through the second inlet and outlet of the second inlet and outlet mechanism.
It should be noted that, the first access mechanism includes two rollers that are disposed up and down and can rotate relatively under the drive of the driving mechanism, and a first access opening is formed between the two rollers, where the width of the first access opening is equal to the thickness of the first optical disc 10, and the width of the first access opening refers to the dimension of the first access opening along the vertical direction. Of course, instead of using two rollers as the first in-out mechanism, a belt transmission mechanism or a mechanism capable of realizing linear transmission may be used as the first in-out mechanism. The second access mechanism has the same structure as the first access mechanism, and the second access mechanism forms a second access port, and the specific structure of the second access mechanism is not described herein. The linear transport mechanism is mainly used for realizing the horizontal transfer of the first optical disc 10 between the first in-out mechanism and the second in-out mechanism. The linear conveying mechanism comprises a plurality of rollers which are arranged at intervals along the horizontal direction, and two ends of each roller are rotatably connected to the conveying frame. The plurality of rollers are rotated in the same direction by the driving mechanism to move the first optical disc 10 in a direction approaching the first access mechanism or in a direction approaching the second access mechanism. The number of rollers may be flexibly set as required as long as the first optical disc 10 can be stably transported, and six rollers are provided in the present embodiment. Of course, in other embodiments, a belt conveyor or other mechanism capable of linear conveyance may be used as the linear conveyor.
It should be noted that the number of the power sources of the driving mechanism may be set to be plural according to the requirement, and the plural power sources are independently driven, so that the first in-out mechanism, the linear conveying mechanism and the second in-out mechanism are independently rotated. Of course, one power source can be used to drive any two or all of the first feeding and discharging mechanism, the linear conveying mechanism and the second feeding and discharging mechanism at the same time, so that the compact structure of the whole driving mechanism is improved.
The intermediate isolation control module 200 can receive the data in the first optical disc 10 read by the intermediate read-only optical disc drive 140, screen the security of the data, and the intermediate isolation control module 200 can perform an isolation function and send the secure extranet data to the intranet module 300. It should be noted that, the intermediate isolation control module 200 specifically includes a control mechanism, an interconnection mechanism, and a screening mechanism, and the control mechanism, the interconnection mechanism, and the screening mechanism of the intermediate isolation control module 200 are all in the prior art, and are not described in detail herein.
With continued reference to fig. 7, the intranet module 300 includes an intranet disc cartridge 310, an intermediate recording optical drive 320, a second transmission component 330, and an intranet read-only optical drive 340, where the intermediate isolation control module 200 can send secure data to the intermediate recording optical drive 320, and the intermediate recording optical drive 320 can receive secure extranet data sent by the intermediate isolation control module 200. The second transmission component 330 is disposed between the middle recording optical disc drive 320 and the intranet read-only optical disc drive 340, the intranet disc cartridge 310 can release the second optical disc 20 to the second transmission component 330, the second transmission component 330 can transmit the second optical disc 20 to the middle recording optical disc drive 320 so as to record the safe data on the second optical disc 20, and the second transmission component 330 can transmit the second optical disc 20 recorded with the data to the intranet read-only optical disc drive 340.

When the first transport assembly 130 descends to the second position, the first transport assembly 130 is staggered with the middle cd-rom drive 140 and the outer net-writing optical drive 120, so that the first optical disc 10 can move out of the whole first transport assembly 130 through the first inlet and outlet or the second inlet and outlet, and the first optical disc 10 without writing space is subjected to disc throwing treatment.
In some embodiments, the first transmission assembly 130 includes a linear motor, and a motor shaft of the linear motor is directly and fixedly connected with the carriage of the first transmission assembly 130, so as to implement driving of the first transmission assembly 130. Of course, in other embodiments, the first transmission assembly 130 may be a combination of a cylinder, a rotating motor and a screw nut mechanism, or a selection motor and a rack and pinion. That is, the power source that can only drive the first transmission assembly 130 to be lifted can be used as the first transmission assembly 130.

Further, as shown in fig. 5, the data ferry machine further includes a second lifting mechanism 700, where the second lifting mechanism 700 is configured to drive the second transmission assembly 330 to lift in a vertical direction, so that the second transmission assembly 330 can move to a third position and a fourth position, the second transmission assembly 330 located at the third position is disposed opposite to the optical drive port of the intranet read-only optical drive 340 and the optical drive port of the intermediate recording optical drive 320, and one side of the second transmission assembly 330 located at the fourth position is configured to pick up and transfer the second optical disc 20 after the intranet disc cartridge 310 is removed, and the other side is configured to perform a disc throwing process on the second optical disc 20. When the second transmission assembly 330 descends to the fourth position, the second transmission assembly 330 is staggered with the intranet rom 340 and the intermediate recording optical disc 320, so that the second optical disc 20 can be moved out of the whole second transmission assembly 330 through the optical disc opening on the second transmission assembly 330, and the second optical disc 20 without the recording space is subjected to disc throwing treatment. It should be noted that the third position and the first position may be located in the same horizontal plane, or may be located in different horizontal planes; the second position and the fourth position may be located in the same horizontal plane or may be located in different horizontal planes.

Further, as further shown in fig. 1 to 3, the data ferry machine further comprises a disk casting box 400, and the disk casting box 400 is used for receiving the first optical disk 10 and the second optical disk 20 after disk casting is completed. In some embodiments, the middle rom 140 and the intranet rom 340 are located on the same side of the data ferry, and the disk slinging box 400 is located below the middle rom 140 and the intranet rom 340.
In this embodiment, the data ferry machine further includes a controller, where the controller may be a centralized or distributed single-chip microcomputer, for example, or may be a distributed single-chip microcomputer, where a control program may be run in the single-chip microcomputer, so as to control the outer net disc 110, the outer net disc drive 120, the first transmission component 130, the middle read-only drive 140, the middle isolation control module 200, the inner net disc 310, the middle recording drive 320, the second transmission component 330, and the inner net read-only drive 340 to implement functions thereof.

The invention also provides a data ferrying method which is used for the data ferrying machine. Specifically, after the data ferry machine receives an external request for ferrying data, as shown in fig. 8, the data ferry method includes the following steps:
s1, the outer net drum 110 releases the first optical disc 10.
Since the outlet of the outer net drum 110 is higher than the first transport assembly 130, the first optical disc 10 released from the outer net drum 110 can be directly dropped onto the first transport assembly 130 under the action of gravity.
S2, the first transmission component 130 transmits the first optical disc 10 to the external network recording optical drive 120, and the external network recording optical drive 120 records the data sent by the external network.
The initial position of the first transmission assembly 130 is located at a first position, that is, when the outer drum 110 releases the first optical disc 10, the first transmission assembly 130 is located at a position opposite to the outer disc drive 120 and the intermediate read-only drive 140.
S3, the first transmission component 130 transmits the first optical disc 10 with the data recorded to the middle ROM 140, and the middle ROM 140 reads the data and sends the data to the middle isolation control module 200.
After the first optical disc 10 exits from the middle cd-rom 140, it needs to determine whether there is any recording space, and according to whether there are two different directions of the recording space, as shown in fig. 9:
first, if the first optical disc 10 still has a recording space, the first optical disc 10 can continue to enter the first transmission component 130 to prepare for the next recording operation to enter the outer network recording optical disc drive 120;
second, if the first optical disc 10 has no recording space, the first lifting mechanism 500 drives the first transmission assembly 130 to descend from the first position opposite to the middle cd-rom 140 to the second position staggered from the middle cd-rom 140, and the first transmission assembly 130 transmits the first optical disc 10 to the disc-throwing box 400 for disc throwing.
S4, the intermediate isolation control module 200 screens the security of the data and sends the security data to the intermediate recording CD-ROM 320.
S5, releasing the second optical disc 20 by the inner network disc barrel 310;
because the outlet of the inner tray 310 is higher than the second transporting assembly 330, the second optical disc 20 released by the inner tray 310 can directly drop onto the roller of the second transporting assembly 330 under the action of gravity.
S6, the second transmission component 330 transmits the second optical disc 20 to the intermediate recording optical disc drive 320, and the intermediate recording optical disc drive 320 records data;
the initial position of the second transmission assembly 330 is located at the third position, that is, when the intranet disc cartridge 310 releases the second optical disc 20, the second transmission assembly 330 is located at a position opposite to the middle recording optical disc drive 320 and the intranet read-only optical disc drive 340.
S7, the second transmission component 330 transmits the second optical disc 20 with the data recorded to the intranet CD-ROM 340.
After the second optical disc 20 exits from the intranet rom 340, it needs to determine whether there is any recording space, and according to whether there are two different directions of the recording space, as shown in fig. 10:
first, if the second optical disc 20 still has a recording space, the second optical disc 20 can continue to enter the second transmission mechanism to prepare for the next recording operation to enter the middle recording optical disc drive 320;
second, if the second optical disc 20 has no recording space, the second lifting mechanism 700 drives the second transmission assembly 330 to descend from the third position opposite to the intranet rom 340 to the fourth position staggered from the intranet rom 340, and the second transmission assembly 330 transmits the second optical disc 20 to the disc throwing box 400 for disc throwing processing.
In some embodiments, the method further comprises the following steps before step S1:
the first lifting mechanism 500 drives the first transmission assembly 130 to lift to the first position, and two ends of the first transmission assembly 130 located at the first position are respectively opposite to the optical disc drive port of the outer network recording optical disc drive 120 and the optical disc drive port of the middle read-only optical disc drive 140.
In some embodiments, the method further comprises the following steps before step S5:
the second lifting mechanism 700 drives the second transmission assembly 330 to lift to the third position, and two ends of the second transmission assembly 330 located at the third position are respectively opposite to the optical disc drive port of the intranet read-only optical disc drive 340 and the optical disc drive port of the intermediate recording optical disc drive 320.
In some embodiments, the method further comprises the following steps before step S1:
the outlet of the outer net drum 110 is disposed higher than the first transport assembly 130 so that the first optical disc 10 removed from the outlet of the outer net drum 110 can drop onto the first transport assembly 130.
In some embodiments, the method further comprises the following steps before step S5:
the outlet of the inner drum 310 is set to be higher than the second transporting assembly 330, so that the second optical disc 20 removed from the outlet of the inner drum 310 can drop onto the second transporting assembly 330.
In some embodiments, the method further comprises the following steps before step S1:
the middle read-only optical drive 140 and the intranet read-only optical drive 340 are arranged on the same side of the data ferry machine;
the disk slinging box 400 is disposed below the middle ROM drive 140 and the inner-net ROM drive 340.
