Further, since the two Host units 20 in the all-in-one machine in this embodiment are both hardware Host systems, the USB attribute of each Host unit is Host, and the two devices with the attribute of Host cannot directly communicate with each other, if data is transmitted to the other Host unit 20 through one of the Host units 20, the Device requiring the main chip 10 as a Device function transfers data between the two Host units 20 to establish a communication connection between the two Host units, thereby completing data transmission.

Example two
Fig. 2 is a flowchart of a data resuming method according to a second embodiment of the present invention, where the data resuming method is executed by a data resuming device, and the data resuming device may be formed by two or more physical entities. The data continuous transmission device may be an all-in-one machine in the above embodiment, and specifically, may be an intelligent interactive tablet. The present embodiment is applicable to a data resume situation after a mobile storage device transmits data to a host unit in the device after a data interruption, and the method may be executed by a device configured to implement data resume by hardware and/or software, and specifically includes the following steps:
s110, acquiring storage information of target data currently transmitted between the mobile storage device and the first host unit.
The first host unit comprises a computer host unit or an android host unit; the mobile storage device comprises a U disk, a mobile hard disk and the like. The mobile storage device is connected to the first host unit through the USB interface and the USB switch, and transmits target data between the first host units. In the process of the target data transmission, the storage information of the target data currently transmitted between the mobile storage device and the first host unit is obtained. The storage information may include a storage path of the target data in the mobile storage device or the first host unit, and specifically, the storage path includes a data name corresponding to the target data.
The transmission of the target data between the mobile storage device and the first host unit can be divided into two cases, the first case is that the target data is stored in the mobile storage device in advance, the target data is transmitted to the first host unit, at this time, a storage path of the target data in the mobile storage device and a transmission path for transmitting the target data to the first host unit are obtained, a data name corresponding to the target data can be known according to the storage path of the target data in the mobile storage device, and the storage path of the target data in the first host unit can be inquired according to the transmission path; the second case is that the target data is pre-stored in the first host unit, the target data is transmitted to the mobile storage device, at this time, a storage path of the target data in the first host unit and a transmission path for transmitting the target data to the mobile storage device are obtained, a data name corresponding to the target data can be known according to the storage path of the target data in the first host unit, and the storage path of the target data in the mobile storage device can be inquired according to the transmission path.
S120, when the mobile storage device is switched to be connected with a second host unit, establishing data connection between the first host unit and the second host unit.
Wherein, the second host computer unit includes computer host unit or tall and erect host computer unit of ann, and first host computer unit and second host computer unit all set up in the inside of same equipment, and this equipment can be the panel computer. In the process of transmitting target data between the mobile storage device and the first host unit, the USB transfer switch switches the data channel to enable the mobile storage device to be connected with the second host unit, and when the connection between the mobile storage device and the first host unit is interrupted, if the target data transmission between the mobile storage device and the first host unit is not completed, the data connection between the first host unit and the second host unit is established after the data connection between the mobile storage device and the second host unit is established. The target data transmission between the mobile storage device and the first host unit may be the target data transmission stored in the mobile device to the first host unit, or the target data transmission stored in the first host unit to the mobile storage device. The first host unit and the second host unit may be the same host unit or different host units. The first host unit and the second host unit may establish a data connection directly or indirectly.
S130, the target data is continuously transmitted between the mobile storage device and the first host unit through the second host unit based on the storage information.
After the first host unit and the second host unit establish data connection, the first host unit sends storage information of target data which is not transmitted to the second host unit, and the second host unit sends a command for data transmission to the mobile storage device directly connected with the second host unit according to the received storage information, and continues to transmit the data of the target data between the mobile storage device and the first host unit. Further, the continuing of the transmission of the target data between the mobile storage device and the first host unit by the second host unit may be resuming the transmission of the target data, that is, resuming the transmission of the data regardless of the amount of the target data transmitted before the interruption, or continuing the transmission based on the target data transmission before the interruption. In the present embodiment, the former is explained as an example.
The working principle of the data continuous transmission method is as follows: a dual-host system is arranged in the tablet personal computer and respectively comprises a first host unit and a second host unit. The first host unit and the second host unit switch data channels with an external storage device through a USB (universal serial bus) selector switch, and the external storage device can be a mobile storage device. When the mobile storage device switches a data channel through the USB switch, the mobile storage device is connected to the first host unit, and performs target data transmission between the mobile storage device and the first host unit, to obtain storage information of target data of current data transmission between the mobile storage device and the first host unit, where the storage information may be a storage path of the target data in the mobile storage device. When the target data is transmitted from the mobile storage device to the first host unit, inquiring the name of the target data, the storage address of the target data stored in the mobile storage device and the storage address of the target data to be stored in the first host unit according to the storage information; when the target data is transmitted from the first host unit to the mobile storage device, the name of the target data, the storage address of the target data stored in the first host unit and the storage address of the target data to be stored in the mobile storage device are inquired according to the storage information.
When the mobile storage device and the first host unit switch the data channel to be connected with the second host unit due to the USB transfer switch in the process of transmitting the target data, the data connection between the mobile storage device and the first host unit is cut off, and the data transmission is interrupted. When the transmission of the target data between the first host unit and the mobile storage device needs to be continued, after the mobile storage device establishes a data connection with the second host unit, the first host unit actively establishes a data connection to the second host unit, and sends storage information to the second host unit to request to continue the data transmission of the target data between the mobile storage device and the first host unit through the second host unit, where the data transmission may be the transmission of data from the mobile storage device to the first host unit through the second host unit, or the transmission of data from the first host unit to the mobile storage device through the second host unit. The data connection between the first host unit and the second host unit may be directly established between the first host unit and the second host unit, or indirectly established through a third unit.
It should be noted that, directly establishing data connection between the first host unit and the second host unit requires higher configuration requirements of the first host unit and the second host unit to ensure the data continuous transmission speed of the first host unit and the second host unit, so that the cost is increased due to the higher assembly configuration of the first host unit and the second host unit; if the first host unit and the second host unit are adopted to indirectly establish data connection through the original third unit in the device, the data transmission speed is ensured, and meanwhile, the cost of the system is not increased.
According to the technical scheme of the embodiment, the storage information of the target data currently transmitted between the mobile storage device and the first host unit is acquired; when the mobile storage equipment is switched to be connected with the second host unit, establishing data connection between the first host unit and the second host unit; the target data is continuously transmitted between the mobile storage device and the first host unit through the second host unit based on the storage information, the problem that the original target data cannot be recovered due to transmission interruption of the original target data caused by switching of data connection channels is solved, and data transmission of the target data between original storage paths is continued on the premise of not increasing system cost.
On the basis of the foregoing embodiment, when the mobile storage device is switched to connect with a second host unit, the establishing of the data connection between the first host unit and the second host unit specifically includes: when the mobile storage device is switched to be connected with a second host unit, a first data connection between the first host unit and a main chip and a second data connection between the second host unit and the main chip are established, and the data connection between the first host unit and the second host unit is established through the first data connection and the second data connection.
The first host unit, the second host unit and the main chip are all units integrated in the same device, and the main chip is preferably a chip unit originally existing in the device and can also be a newly added chip unit. When a direct data channel between the mobile storage device and the first host unit is cut off, the mobile storage device is switched to be connected with the second host unit, if target data transmission between the mobile storage device and the first host unit is not finished, a first data connection is established between the first host unit and the main chip, a second data connection is established between the second host unit and the main chip, the main chip serves as an intermediate medium between the first host chip and the second host chip to indirectly establish the data connection, and a data transmission channel is established between the mobile storage device and the first host unit through 'first data connection-main chip-second data connection'. The first data connection and the second data connection can establish data connection in a wired mode such as a USB line and the like, and can also establish data connection in a wireless mode.
On the basis of the foregoing embodiment, the first host unit is a computer host unit, the second host unit is an android host unit, and when the mobile storage device is switched to the second host unit for connection, the data connection between the first host unit and the second host unit is established, which specifically further includes: and establishing SPI communication connection between the second host unit and the main chip, wherein the SPI communication connection is used for transmitting the storage information and the transmission state of the target data.
When the second host is the android host unit, the transmission rate of the USB data path between the second host unit and the main chip is slower, so that besides the USB data path, SPI communication connection is added between the second host unit and the main chip to assist transmission. SPI is a synchronous serial data bus with a simple protocol, and has a low transmission rate compared to the USB data path, which is only a few megabbps. The SPI is used to transmit information with a small data amount and low requirement, such as storage information and transmission state of target data. The storage information of the target data comprises the name of the target data and the storage path of the target data in the mobile storage device and the first host unit.
The following describes an exemplary embodiment of the present invention:
fig. 3 is a schematic structural diagram of an all-in-one machine of the application data retransmission method according to the second embodiment of the present invention. As shown in fig. 3, the mobile storage device is connected to the all-in-one machine through the USB interface 40, and selectively connected to the computer host unit 201 or the android host unit 202 through the USB switch 30. In this example, the mobile storage device initially establishes a data connection with the computer main unit 201 through the USB switch 30, and data copying is performed on the mobile storage device through a computer path between the USB switch 30 and the computer main unit 201. In the data copying process, the computer host unit 201 captures the target data in the removable storage device in real time, and knows the storage path of the target data in the removable storage device, the transmission path between the removable storage device and the computer host unit 201, and the transmission state on the computer channel. The storage path comprises a storage address and a data name of the target data in the mobile storage device, the transmission path comprises a storage address of the target data in the host computer unit, and the transmission state in the computer channel refers to whether the host computer unit copies the target data.
The computer host unit 201 transmits the acquired transmission state to the main chip 10 through the USB data path, and the main chip 10 can know whether the computer host unit 201 copies the target data of the mobile storage device in real time. If the data transmission channel is switched during the process of copying the target data, the USB switch 30 interrupts the data connection with the computer host unit 201, and establishes the data connection with the android host unit 202. At this time, the main chip 10 determines whether the computer host unit 201 is copying the mobile storage device, and if so, a series of actions of data continuous transmission are started, that is, a first data connection between the main chip 10 and the computer host unit 201, a second data connection between the main chip 10 and the android host unit 202 are established, and data transmission is performed again on the target data through the first data connection and the second data connection.
The main chip 10 acquires, from the computer host unit 201 via USB, storage information of target data currently transferred between the mobile storage device and the computer host unit 201, the storage information including a storage path of the target data in the mobile storage device and a storage path copied to the computer host unit 201, the storage path including a data name of the target data and a storage address in the mobile storage device, and the transfer path including a storage path of the target data copied to the computer host unit 201. The data connection between the main chip 10 and the android host unit 202 includes a USB data path and an SPI path, the USB data path is used for transmitting target data, and the SPI path is used for transmitting storage information and a transmission state of the target data.
The main chip 10 informs the android host unit 202 of the need to start the data continuous transmission function and the storage information of the target data to be transmitted through the SPI channel, and the data name of the target data, the storage path of the target data in the mobile storage device and the storage path of the target data in the host computer module can be known according to the storage information. The android host unit 202 reads target data of the mobile storage device connected with the android host unit 202 according to the information transmitted by the main chip 10, and transmits the target data to the main chip 10 through the USB data path, and the main chip 10 acquires the target data transmitted from the android host unit 202 and transmits the target data to the computer host unit 201 through the USB data path.
EXAMPLE III
Fig. 4 is a flowchart of a data resuming method according to a third embodiment of the present invention, which is embodied on the basis of the second embodiment. The method is suitable for a case where target data is stored in the mobile storage device and the target data is transmitted from the mobile storage device to the first host unit, where the storage information is a storage path of the target data in the mobile storage device and the first host unit, and as shown in fig. 4, the method specifically includes:
step S310, obtaining the storage information of the target data currently transmitted between the mobile storage device and the first host unit.
The mobile storage device is connected to the first host unit through the USB transfer switch switching data channel and transmits target data to the first host unit. In the process of the target data transmission, the storage information of the target data currently transmitted between the mobile storage device and the first host unit is obtained. The storage information may be a storage path of the target data in the mobile storage device, and a data name corresponding to the target data, a storage address where the target data is stored in the mobile storage device, and a storage address where the target data is to be sent to the first host unit are queried according to the storage information.

When the transmission of the target data to the first host unit is not completed, the USB transfer switch switches the data channel so that the mobile storage device is connected with the second host unit, and the transmission process of the target data between the mobile storage device and the first host unit is interrupted. At this time, if it is necessary to continue transmitting the target data to the first host unit, a first data connection is established between the first host unit and the main chip, a second data connection is established between the second host unit and the main chip, the main chip serves as an "intermediate medium" to indirectly establish a data connection between the first host chip and the second host chip, and the target data continues to be transmitted between the mobile storage device and the first host unit through a data path of "the first host unit, the main chip, and the second host unit".
Step S330, sending the storage information to the second host unit, so that the second host unit reads the target data from the mobile storage device according to the storage information, and transmits the target data to the first host unit.
And inquiring the name of the target data which is not transmitted, the address of the target data stored in the mobile storage device and the storage address of the target data to be stored in the first host unit according to the storage information. The second host unit receives the storage information, reads the target data stored in the mobile storage device according to the storage information and sends the target data to the main chip; the main chip receives the target data and forwards the target data to the first host unit, and the first host unit receives the target data and stores the target data in an original storage path of the target data. The data continuous transmission can be all retransmission, and covers the previous target data; or the transmission may continue at the interrupted target data location. In addition, in the data transmission process, the current data transmission state is correspondingly displayed on the screen. For example, the progress of transmission completion is displayed, and if the data transmission is retransmitted, the progress bar of the data transmission is redisplayed from the beginning; if the transmission is continued at the target data location of the interruption, the data transmission may be prompted to be interrupted and resumed.
According to the technical scheme of the embodiment, the storage information of the target data currently transmitted between the mobile storage device and the first host unit is acquired; when the mobile storage equipment is switched to be connected with the second host unit, establishing data connection between the first host unit and the second host unit; and sending the storage information to the second host unit so that the second host unit reads the target data from the mobile storage device according to the storage information and transmits the target data to the first host unit, thereby solving the problem that the original target data transmission is interrupted and cannot be recovered due to switching of a data connection channel in the process of transmitting the target data to the first host unit when the target data is stored in the mobile storage device, and realizing the data continuous transmission of the target data between original storage paths on the premise of not increasing the system cost.
