Step S110: When the external device is connected to the terminal through the interface, receiving a device descriptor request sent by the terminal, and requesting a return response according to the device descriptor;

Step S120: receiving an operation request sent by the terminal, sending the operation request to the server, or converting the operation request into a network request, and sending the operation request to the server;

Step S130: Receive data returned by the server according to the operation request or the network request, and forward the returned data to the terminal.

The method of the present invention can be implemented according to a corresponding program, and the program runs on an embedded operating system included in the external device. The external device also includes a processor and memory to ensure the proper operation of the embedded system. The various steps of the method of the invention are described in detail below.

In step S110, the external device has an interface connected to the terminal through the interface. The terminal can be a user's computer, a mobile phone, a set-top box, and a printer. When the external device is connected to the terminal, the terminal sends a device descriptor request to the external device, requests the external device to describe itself, and after receiving the device descriptor request, returns a response and describes itself as a general-purpose device.

In view of applicability and compatibility, in one embodiment, the response includes a response of the external device to the mass storage device, and the like. The mass storage device is a secondary storage device and is a general term for memory. It includes a USB (Universal Serial Bus) mass storage device.

Taking a large-capacity storage device as a USB mass storage device as an example, when receiving a device descriptor request sent by the terminal, the external device is described as a USB mass storage device, and the terminal recognizes the external device as a USB mass storage device. .

When the external device is described as a USB mass storage device, the interface of the external device is set to a USB interface, and the terminal is connected through the USB interface. When the external device is described as another general-purpose large-capacity storage device, the interface of the external device is set to correspond to the interface supported by the large-capacity storage device, and the interface is connected to the terminal through the supported interface.

Since the terminal recognizes the external device as a general-purpose device, the built-in driver can be used. For example, the general operating system integrates the USB protocol driver, and when the external device is a USB mass storage device, the terminal can use the built-in USB protocol driver.

Since the external device acts as a data exchange device, it needs to establish a connection with the server. Therefore, in an embodiment, when the external device is connected to the terminal through the interface, the method may further include:

Driving the wireless network card or the wired network card in the external device, and connecting the wireless network card or the wired network card to the network by using the information in the configuration file.

When the external device is connected to the terminal, the embedded system is powered on. After the embedded system is started, the wireless network card or the wired network card is driven, and the external device is automatically connected to the network by a preset configuration. The user can also set the power module in the external device and automatically connect to the network through its own power module.

In step S120, since the terminal recognizes the external device as a general-purpose device, the user can transmit an operation request using a normal operation, wherein the operation request includes a read-write request and a query request and the like. After receiving the operation request of the terminal, the external device can convert the operation request into a corresponding network request (including but not limited to HTTP/FTP/SAMBA) by using a custom protocol, and then send the request to the server, or directly the operation request. Forward to the server and let the server convert itself. The server is located locally or on the Internet and can be a smart interactive tablet.

Taking a USB mass storage device as an example, the operation of the USB mass storage device follows the SCSI (Small Computer System Interface) protocol, and the terminal operates on the USB mass storage device (query partition structure, read file) The directory, read and write delete files, etc.) are eventually converted to SCSI commands, which are sent to the USB mass storage device via USB packaging. For example, if the USB mass storage device is turned on, the operating system of the terminal actually reads the file configuration table of the device by using the read request of the SCSI command (a data area in the flash memory file system indicates that the file system is in the file system). What files are included). The external device then converts these requests into network requests for transmission to the server or sends them directly to the server without conversion.

When the operation request is converted, the operation request may be converted into a corresponding string. For example, the read/write request sent by the terminal generally includes a read/write position and a read/write length information, etc., and the read/write request may be converted into a string by the string. A string of the form of the requested type + requested location + requested data length, etc. It should be noted that there are multiple methods for converting an operation request into a network request, and the user can convert the operation request by using other methods in the prior art, which is not limited by the present invention.

In step S130, the server returns the data after performing the corresponding operation according to the operation request or the network request. In one embodiment, the returned material may include an executable program of the terminal. An executable is an executable program that can be floated in the operating system's storage space. The data returned by the server may also be other data except the executable program, for example, a read/write request sent by the terminal to a certain magnetic area, and the server finds the corresponding position and the corresponding length according to the read/write request, and correspondingly The data is passed back to the external device. For another example, the terminal sends a request for querying whether the device is ready, and the server returns whether the device is ready according to the current state.

In one embodiment, the executable program can include a communication code and a screen data capture code. The communication code includes a code for communication between the terminal and the external device and a code for communication between the external device and the server. The communication code enables the terminal to transmit the captured audio and video image data to the external device by the code, and the external device transfers the sounding video image data to the server. The screen data capture code includes an encoding code for audio capture by a terminal API (Application Programming Interface) and a video or image encoding code for screen capture by a terminal API. Or two.

The external device forwards the returned data to the terminal in response to the request initiated by the terminal. For example, taking a USB mass storage device as an example, the external device forwards the returned data to the terminal according to the USB Mass Storage protocol. Since there is a communication code between the external device and the terminal at this time, the forwarding of the data is directly implemented by the communication code.

In an embodiment, after forwarding the returned data to the terminal, the method may further include:

Receiving audio and video image data transmitted by the terminal by the communication code, wherein the audio and video image data is obtained by the screen data capture code;

The audiovisual image data is forwarded to the server for display.

After the audio and video image data is captured, the terminal generally encodes the audio and video image data, and sends the encoded data to the server through an external device. After the server receives the encoded data, it decodes and displays it.

The invention describes the external device as a universal device, such as a large-capacity storage device, and uses the built-in driver of the terminal, and the terminal automatically completes the installation of the driver when connecting with the external device. The invention does not need to be configured, and the user can access the file stored on the server as if it were a normal device, and all the requests are converted by the external device, and the operation request of the terminal is converted into the operation of the network storage server. The present invention deviates from the reliance on the operating system and the client, and can be used on some devices or systems that are not open.
