Detailed ways

The following descriptions are of preferred embodiments of the invention. Its purpose is to illustrate the general principle of the present invention and should not be regarded as a limitation of the present invention. The scope of the present invention should be defined by the claims.

In FIG. 1 , a computer system 100 includes a processor 1 , a main memory 2 , a display 3 , an input device 4 , a host controller 5 and a storage device 6 . The host controller 5 is connected to the USB port 7 . The connector 122 of the integrated peripheral device 120 is connected to the USB port 7 and includes devices 123-125 respectively providing different functions. The switching device 121 can connect or disconnect the devices 123-125 to the computer system 100, respectively. It should be understood that the devices 123-125 can interpret the corresponding switching commands to control the switching device 121 respectively. Among the integrated peripheral devices 120, the device 123 connected to the computer system 100 is called a default active device, which can communicate with the computer system 100 and control the switching device 121 according to the switching command (command) from the computer system 100. , and then switch the operating device in the integrated peripheral device 120 .

The storage device 6 stores application programs 61 and 62 and an operating system 63 . The applications 61 and 62 correspond to the devices 124 and 125 respectively. The drivers 611 and 621 are used to drive the devices 124 and 125 respectively. The processor 1 can load the application programs 61 , 62 , operating system 63 , drivers 611 and 612 into the main memory 2 for execution. One of the devices 123 - 125 may be preset as a default operating device integrated with the peripheral device 120 . In the following description, device 123 is a storage device (mass storage), supports USB massstorage class and is preset as a default operating device integrating peripheral device 120, while other devices (device 124 and 125) are not connected to the computer system 100. The device 124 is a webcam, and the device 125 is a TV receiver. However, it should be understood that various other devices may be integrated in the integrated peripheral device. Although the integrated peripheral device is connected to the computer system through the USB interface, it is not limited thereto. The integrated peripheral device can also be connected to the computer system through other interfaces such as Firewire.

The computer system 100 receives an operation instruction from the input device 4, and the processor 1 sends a switching command from the computer system 100 to the integrated peripheral device 120 according to the operation instruction, so as to switch the operating device in the integrated peripheral device 120 from the device 123 to the device 124 or device 125. The processor 1 can automatically send a switching command to switch the operating device according to the executed application program. For example, the operating device is automatically switched when the application program is activated or terminated, or the operating device is automatically switched according to the active window in the operating system environment, as described below.

2, when the integrated peripheral device 120 is connected to the computer system 100, the computer system 100 detects the default operating device of the integrated peripheral device 120, namely the storage device 123 (step S200). The input device 4 receives a user operation instruction to activate the application program 61 of the corresponding device 124 in the computer system 100 . When the processor 1 executes the application program 61 (step S202), the application program 61 issues a first switching command, which is transmitted to the integrated peripheral device 120 through the host controller 5 and the USB port 7 (step S204). The first switching command may be a private command conforming to the Universal Serial Bus (USB) mass storage class standard. Figure 4 shows a schematic diagram of the format of a custom command. The content of the first switching command can be recorded in the 15th to 30th bytes of the private command in FIG. 4 .

When the integrated peripheral device receives the switching command, the storage device 123 controls the switching device 121 according to the private command, interrupts the connection between the computer system 100 and the storage device 123, and the switching device 121 establishes the connection between the computer system 100 and the device 124. online. Accordingly, the integrated peripheral device 120 switches the operating device from the device 123 to the device 124 in response to the switch command. It should be understood that, in other embodiments, the operating system 63 may cooperate with the driver 611 of the device 124 to issue the first switching command.

Next, the computer system 100 detects the operating device integrated with the peripheral device 120 , that is, the device 124 (network camera) (step S206 ), and interacts with it (step S208 ). The input device 4 receives a user operation instruction to close the application program 61 of the corresponding device 124 in the computer system 100 . When the processor 1 terminates the application program 61 (step S210), the application program 61 issues a second switching command (step S212). The second switching command may be a vendor command (vendor command) in the Universal Serial Bus (USB) standard. Figure 5 shows a schematic diagram of the format of a vendor command. The content of the second switching command can be recorded in the first byte of the manufacturer command in FIG. 5 .

The device 124 controls the switching device 121 according to the private command to switch the operating device of the integrated peripheral device 120 to the storage device 123 . It should be understood that, in other embodiments, the second switching command may also be issued by the operating system 63 or the driver 611 of the device 124 . The computer system 100 detects again that the operating device of the integrated peripheral device 120 is replaced with the storage device 123 (step S214 ).

However, the integrated peripheral device 120 can also switch the operating device before the application program 61 is closed, as an example will be described below.

3, when the integrated peripheral device 120 is connected to the computer system 100, the computer system 100 detects the default operating device of the integrated peripheral device 120, namely the storage device 123 (step S300). The input device 4 receives a user operation instruction to activate the application program 61 of the corresponding device 124 in the computer system 100 . When the processor 1 executes the application program 61 (step S302), the application program 61 issues a third switching command, which is transmitted to the integrated peripheral device 120 through the host controller 5 and the USB port 7 (step S304). When the integrated peripheral device receives the third switching command, the storage device 123 controls the switching device 121 according to the third switching command, interrupts the connection between the computer system 100 and the storage device 123, and the switching device 121 establishes the connection between the computer system 100 and the storage device 123. Connection of device 124.

Next, the computer system 100 detects the operating device integrated with the peripheral device 120 , that is, the device 124 (network camera) (step S306 ), and interacts with it (step S308 ). The input device 4 receives a user operation instruction to activate the application program 62 of the corresponding device 124 in the computer system 100 . When the processor 1 executes the application program 62 (step S310), the application program 62 issues a fourth switching command (step S312). The device 124 controls the switching device 121 according to the fourth switching command to switch the operating device of the integrated peripheral device 120 to the device 125 (television signal receiver). It should be understood that, in other embodiments, the fourth switching command can also be issued by the operating system 63 or the driver 621 of the device 125 . The computer system 100 again detects that the operating device integrated with the peripheral device 120 is the device 125 (step S314 ). The processor 1 terminates the application program 61 (step S316).

Even if the manufacturer command corresponding to the device 124 is issued to switch the operating device to the device 123 when the application program 61 is terminated in step S316, since the operating device of the integrated peripheral device 120 is the device 125, the manufacturer command of the device 124 cannot be recognized, so it can still operate normally. Instead of being switched to device 123.

The computer system 100 can automatically switch the operating device according to the operating window (active window) in the operating system environment, and an example will be described below.

Referring to FIG. 6, the operating system 63 detects whether there is switching of the operation window (step S600)? If so, the operating system 63 identifies the application program of the current operating window (step S602) and determines the device corresponding to the application program in the integrated peripheral device 120 (step S604), and sends a switching command to the integrated peripheral device 120 to switch the corresponding one of the operating window. The device is an operating device (step S606).

Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Anyone with common knowledge in the technical field can make various changes and modifications without departing from the spirit and scope of the present invention. , so the protection scope of the present invention shall prevail as defined by the appended claims.
