Detailed Description
The file sharing method based on the multi-system all-in-one machine is applied to a scene of file sharing or file transmission between two hosts in the multi-system all-in-one machine. The present multisystem all-in-one machine includes a first host and a second host, where the first host is deployed with a first operating system, the first operating system may be, for example, a Windows, linux, or Unix operating system, and the second host is deployed with a second operating system, which may be, for example, an Android operating system. The first host and the second host operate separately, but share some peripheral devices, such as an operating screen or a Micro Controller Unit (MCU).
In many scenarios, the first host and the second host need to perform file sharing, such as copying a file stored in the first host to the second host, or copying a file stored in the second host to the first host, and so on. At present, when a file is transferred, the file can be generally transferred in two ways:
the first method comprises the following steps: and carrying out file transmission through a network. Because the first host and the second host work separately, network cards can be installed in the first host and the second host, so that network connection is established between the first host and the second host through the network cards to realize file sharing.
And the second method comprises the following steps: file transfer is via serial port or I2C. Specifically, a host computer that needs to perform file transmission sends a file to be transmitted to another host computer according to a preset transmission rate.
In the first method, since the network cards need to be installed in the first host and the second host, the cost of file sharing is high. In the second mode, since the bytes are sequentially transmitted according to the transmission rate during file transmission, the transmission rate is low, and during the transmission of the bytes, a packet loss phenomenon is easily caused, which causes a file transmission error.
In view of the above problems, an embodiment of the present application provides a new multi-system all-in-one machine, where, in view of that an existing multi-system all-in-one machine includes a first host and a second host that work separately, if a Universal Serial Bus (USB) communication connection can be established between the first host and the second host when file transmission is performed, and the second host is directly mounted to the first host as an external device, file sharing between the first host and the second host can be quickly achieved. Based on this, in the multi-system all-in-one machine provided in the embodiment of the present application, on the basis of a current multi-system all-in-one machine, the multi-system all-in-one machine further includes a switch module, the switch module is respectively connected with the first host and the second host, when a user wants to share files between the two hosts, a control instruction can be sent to the control module to control the switch module to be turned on, so that the first host and the second host establish a USB communication connection, the second host is mounted to the first host as an external device, at this time, file sharing between the two hosts can be rapidly performed, not only can the cost of file sharing be reduced, but also the phenomenon of making mistakes during file transmission can be avoided, and the accuracy of file sharing is improved.
Fig. 1 is a schematic structural diagram of a multi-system all-in-one machine provided in an embodiment of the present application, and as shown in fig. 1, the multi-system all-in-one machine 10 includes a first host 12 deployed with a first operating system, a second host 14 deployed with a second operating system, a control module 11, and a switch module 13, where the switch module 13 is connected to the control module 11, the first host 12, and the second host 14, respectively. The control module 13 is configured to control the switch module 13 to be turned on or off, when the switch module 13 is in an on state, the first host 12 and the second host 14 establish a USB communication connection, and when the switch module 13 is in the on state, the first host 12 is configured to perform file sharing based on the USB communication connection between the first host 12 and the second host 14 according to an operation instruction for performing file sharing executed by a user on a display interface controlled by the first host.
Specifically, the first operating system and the second operating system may be different, for example, the first operating system deployed in the first host 12 may be a Windows, linux, or Unix operating system, and the second operating system deployed in the second host 14 may be an Android operating system. In addition, the first operating system and the second operating system may be the same, for example, both of the first operating system and the second operating system are Android systems.
It should be noted that, in the embodiments of the present application, a Windows operating system is deployed in a first host, and an Android system is deployed in a second host, as an example, the first host is a PC, the second host is an Android, for other operating systems, the specific structure of the multisystem all-in-one machine and the implementation manner of file sharing are similar to those when the first host is a PC and the second host is an Android, and details are not repeated here.

In addition, the multi-system all-in-one machine also comprises a controller used for controlling the display interface, and the controller controls whether the display interface is controlled by the first host computer or the second host computer or controlled by the first host computer and the second host computer simultaneously according to the operation of a user. When the display interface is controlled by the first host and the second host at the same time, the display interface may be divided according to a preset ratio, for example, the display interface is divided into a left part and a right part, where a left part is controlled by the first host, that is, displays the content or the file controlled by the first host, and a right part is controlled by the second host, that is, displays the content or the file controlled by the second host.
After receiving a first operation instruction, executed by a user on a first display interface, for requesting file sharing, the control module 11 sends a control signal to the switch module 13, and the switch module 13 controls itself to be in a conducting state according to the control signal, at this time, the first host 12 and the second host 14 establish USB communication connection.
In which the first host 12 and the second host 14 establish a USB communication connection, it can be understood that the second host 14 is mounted as an external device in the first host 12, and therefore, the drive letter information of the second host 14 can be detected in the first host 12.
When performing file sharing, a user may execute a second operation instruction, such as a copy instruction or a copy instruction of a file, on a second display interface controlled by the first host 12, and the first host 12 may copy the file in the first host 12 to the memory corresponding to the drive letter of the second host 14 or may copy the file in the memory corresponding to the drive letter of the second host 14 to the first host 12 based on the established USB communication connection with the second host 14.
The multi-system all-in-one machine in the embodiment comprises a first host, a second host, a control module and a switch module respectively connected with the first host, the second host and the control module, wherein the control module is used for controlling the state of the switch module, if the switch module is in a conducting state, USB communication connection can be established between the first host and the second host, and when the first host carries out an operation instruction for carrying out file sharing according to a user, file sharing is carried out based on the USB communication connection between the first host and the second host. The first host and the second host can directly share files based on USB communication connection without other hardware equipment, so that the cost of file sharing can be reduced. In addition, the file sharing is carried out through the USB communication connection, so that the file sharing efficiency can be improved, the phenomenon of error in file transmission in the prior art can be avoided, and the accuracy of file sharing is improved.

When the switch module 13 is in the off state, the control module 11 controls the second USB transmission port of the second host 14 to be in the host mode, so that the second host 14 and the external USB transmission port 15 of the multi-system all-in-one machine 10 establish a communication connection.
Specifically, when the switch module 13 is in an off state, the control module 11 controls the second USB transmission port of the second host 14 to be switched to the external USB transmission port 15 of the multi-system all-in-one machine 10, and sets the second USB transmission port of the second host 14 to be in a host mode (host mode), so that one external USB signal input port can be added, and flexibility of file transmission is improved.
In addition, when the switch module 13 is in the off state, the first host 12 and the second host 14 are in a completely isolated state, so that the security of the system can be increased.
Illustratively, the switch module 13 may include an analog switch chip, a transistor, or a transistor to reduce the cost of file transfer.
Next, a specific structure of the multisystem all-in-one machine is described by taking the first host as a PC and the second host as an Android.

Fig. 5 is a schematic diagram of a first display interface, as shown in fig. 5, when a user selects an automatic control, a switch that determines whether to perform file sharing may appear in the first display interface, and if the user wants to perform file sharing, the user may click the switch corresponding to the file sharing to turn on the switch, and at this time, the user may send a first operation instruction for requesting file sharing to the control module through the first display interface.
After receiving a first operation instruction triggered by a user, the control module controls the switch module to be in a conducting state according to the first operation instruction so as to control the first host and the second host to establish USB communication connection.
In a possible implementation manner, the first host includes a first USB transmission port, and the second host includes a second USB transmission port, and when the switch module is turned on, the first USB transmission port and the second USB transmission port may be directly connected. When the first host and the second host are controlled to establish the USB communication connection, the control module may control the second USB transmission port of the second host to be in the device mode, and in the device mode, control the first host and the second host to establish the USB communication connection.
Specifically, the user may send different operation instructions to the control module by clicking the switch corresponding to the file sharing in fig. 5, and the control module may further control the second USB transmission port of the second host to be in different operation modes when controlling the on and off states of the switch module according to the different operation instructions. For example, when the switch module is in the on state, the control module controls the second USB transmission port of the second host to be connected with the first USB transmission port of the first host, that is, controls the USB channel of the second host to be switched to be connected with the first host, and at the same time, the control module controls the second USB transmission port of the second host to be set to a USB device mode (device mode), so that the second host is accessed to the first host as an external device, thereby achieving the purpose that the first host can access the content or file of the second host.
In this mode, when the switch module is in the on state, the second USB transmission port of the second host is controlled to be in the USB device mode, and in the USB device mode, the first host and the second host are controlled to establish the USB communication connection, so that the first host and the second host can share files through the USB communication connection, the file sharing efficiency can be improved, and the cost can be reduced.
Furthermore, when a second USB transmission port of the second host is in a USB device mode, the first host detects its own first USB transmission port, and if it is detected that the first USB transmission port is communicated with the second USB transmission port, the second host is mounted in the first host, so that the first host and the second host establish a USB communication connection.
Fig. 6 is a schematic diagram of a directory interface of the first host before the first host and the second host establish the USB communication connection, as shown in fig. 6, when the switch module is in the off state, because the USB communication connection is not established between the first host and the second host, the second host is not detected in the first host, and at this time, the file directory of the first host only includes the locally saved file or the locally installed disk.
Fig. 7 is a schematic view of a directory interface of the first host after the first host and the second host establish a USB communication connection, as shown in fig. 7, when the switch module is in a conducting state, the second USB transmission port of the second host is in a USB device mode, at this time, the first host may detect its own first USB transmission port to detect whether the first USB transmission port is connected with the second USB transmission port, if so, the second host is mounted in the first host, which is equivalent to directly accessing the second host to the first host as an external device, so that the USB communication connection is established between the first host and the second host. At this time, the file directory of the first host includes not only the locally saved file or the locally installed disk, but also identification information of the second host, such as displaying an AA drive letter.
The first USB transmission port is communicated with the second USB transmission port, which can be understood as the second USB transmission port of the second host is directly plugged into the first USB transmission port of the first host.
In this embodiment, when it is detected that the first USB transmission port is communicated with the second USB transmission port, the second host is mounted to the first host, so that the first host can access the content in the second host, and the purpose of file sharing is achieved.
In addition, when the user wants to stop the file sharing, a third operation instruction for requesting to stop the file sharing can be sent to the control module through the first display interface, and the control module can control the switch module to be switched off according to the third operation instruction.
Specifically, the user may click the switch corresponding to the file sharing in fig. 5 to send a third operation instruction for requesting to stop the file sharing to the control module, so that the control module is in an off state. When the switch module is in an off state, the control module sets a second USB transmission port of the second host to a host mode (host mode), and the host mode is used for indicating that the second host and an external transmission port of the multi-system all-in-one machine establish USB communication connection.
When the switch module is in an off state, the control module controls to switch the USB channel of the second host to the external USB transmission port, and simultaneously switches the second USB transmission port of the second host from a USB device mode to a host mode (host mode) to use the second USB transmission port as an external USB signal input port.
In this mode, when the switch module is in the off state, the second USB transmission port of the second host can be controlled to be in the host mode, so that the USB communication connection is established between the second host and the external transmission port of the multi-system all-in-one machine, and therefore complete isolation of the operating systems of the first host and the second host can be achieved, and safety is improved. In addition, the second USB transmission port is used as an external USB signal input port, so that the flexibility of file transmission can be increased.
Step 402: the first host responds to a second operation instruction for file sharing executed on a second display interface controlled by the first host by a user, and according to the second operation instruction, file sharing is carried out based on USB communication connection between the first host and the second host.
In this step, after the USB communication connection is established between the first host and the second host, the user may execute a second operation instruction on a second display interface controlled by the first host, where the second operation instruction is used to indicate that file sharing is performed. Fig. 8 is a schematic diagram of a second display interface, and as shown in fig. 7 and 8, a user may click on the local disk C to copy the file ggg in the local disk C to the second host, at this time, the user may click on the file ggg, or click on a control such as copy, cut, or send, to send a second operation instruction to the first host. The first host copies the file ggg to the second host based on the USB communication connection between the first host and the second host according to the received second operation instruction.
Similarly, as shown in fig. 7, the user may also click on the device AA to open the file in the second host, and according to the same operation as described above, the file in the second host may be copied to the first host, so as to implement file sharing.
For example, since the second display interface is an interface shared by the first host and the second host, when the file is shared, since the drive letter of the second host is displayed in the first host, the user needs to trigger a fourth operation instruction through the first display interface, where the fourth operation instruction is used to request to switch the display interfaces. The control module can switch the first display interface into a second display interface controlled by the first host according to the received fourth operation instruction.
Specifically, as shown in fig. 5, assuming that the first host is a PC with a Windows operating system deployed therein, and the second host is an Android with an Android operating system deployed therein, the user may click a "Windows" control (shown by a dotted line in fig. 5) in the first display interface to switch the first display interface to a second display interface controlled by the first host. After the display interfaces are switched, the first host carries out file sharing based on the USB communication connection between the first host and the second host according to a second operation instruction which is executed on a second display interface controlled by the first host by a user and carries out file sharing after receiving the second operation instruction.
In this embodiment, before the file sharing is performed, the display interface is switched first, so that the user operation can be facilitated, and the user experience can be improved.
According to the file sharing method based on the multi-system all-in-one machine, a control module responds to a first operation instruction which is executed by a user on a first display interface and used for requesting file sharing, and controls a switch module to be in a conducting state according to the first operation instruction so as to control a first host and a second host to establish USB communication connection, the first host responds to a second operation instruction which is executed by the user on a second display interface controlled by the first host and used for file sharing, and according to the second operation instruction, file sharing is carried out based on the USB communication connection between the first host and the second host. The first host and the second host can directly transmit and share files based on the internal USB of the multi-system all-in-one machine without other hardware equipment, so that the cost of file sharing can be reduced. In addition, the mode of sharing files based on the USB communication connection not only can improve the efficiency of sharing files, but also can avoid the phenomenon of errors in file transmission in the prior art and improve the accuracy of sharing files. In addition, the same file can be simultaneously opened and browsed in the window system and the Android system.
