detailed description

The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and preferred embodiments.

As shown in FIG. 1, a method for updating data includes the steps of:

S110. Receive an apparatus descriptor request sent by the terminal when the external device is connected to the terminal through the interface, and return a response according to the device descriptor request.

S120: Receive an operation request sent by the terminal, send the operation request to a server, or convert the operation request into a network request, and send the operation request to the server;

S130. Receive, by the server, the returned data according to the operation request or the data returned by 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, a printer, and the like. 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 device.

In view of applicability and compatibility, in one embodiment, the response includes the response of the external device to a mass storage device, and the like. The mass storage device is a secondary storage and is a general term for storage, including 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 large capacity. Storage device.

When an external device is described as a USB mass storage device, the interface of the external device is set to a USB interface, and is connected to the terminal through the USB interface. When an 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 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 terminal. The driver of the USB protocol.

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 the following steps:

The wireless network card or the wired network card in the external device is driven, and the wireless network card or the wired network card is connected to the network through 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 through a preset configuration. The user can also set the power module in the external device and automatically access 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 from the terminal, the external device can convert the operation request into a corresponding network request (including but not limited to HTTP/FTP/SAMBA) through a custom protocol, and then send it to the server, or directly forward the operation request to the operation request. Server, 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 the partition structure and read the file). The directory, read and write delete files, etc.) are eventually converted to SCSI commands and 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 by the SCSI command, and reads the file allocation table of the device (a data area in the flash file system), indicating which files are included in the file system. ). The external device then translates these requests into network requests for delivery 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 request by a string. The type + the location of the request + the requested data length and other forms of the string. It should be noted that there are multiple methods for converting an operation request into a network request, and the user may 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 data according to the operation request or the network request to perform the corresponding operation. In one embodiment, the returned data may include an executable program of the terminal. An executable program 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 than the executable program, for example, a read/write request sent by the terminal to a certain sector, and the server finds the corresponding position and corresponding length data according to the read/write request, and returns the corresponding data. Give an external device. For another example, the terminal issues a request to query 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 communication code and 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 through the code, and the external device converts the pronounced video image data to the server. The screen data capture code includes any one or two of an encoding code for audio capture through a terminal API (Application Programming Interface) and a video or image encoding code for screen capture through a terminal API. .

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 realized by the communication code.

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

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

The audio and video 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 performs decoding display.

The present invention describes an external device as a general-purpose device, such as a mass storage device, and uses a built-in driver of the terminal, and the terminal automatically completes the installation of the driver when connected 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 invention departs from the dependence on the operating system and the client and can be used on some devices or systems that are not open.
