In this embodiment, a first universal serial bus master controller and a multi-port USB hub 513 are illustrated as an embodiment. The universal serial bus switching circuit 511 can include a human interface interface H (HID p〇rt) 5111, a main port 511 5102, and a hub port 5113. An upstream port of the universal serial bus hub 513 is connected to the image signal unit 30, and a downstream port is connected to the hub port 5113. One end of the first universal serial bus master controller 512 is connected to the main port 5112, and the other end is connected to the system controller 521 of the function application unit 52. When the universal serial bus bar 21 and the universal serial bus keyboard 22 are respectively connected to the human interface interface 111 5111, the system controller 521 of the function application unit 52 returns an input switching signal 52c to specify the universal serial port. The bus bar 21 and the universal serial bus keyboard 22 are switched to the hub connection 埠 51丨3 to connect the common_column bus line 11 513 or switch to the main link 5112 to connect the first-general serial bus main controller 512. When the input switching signal 52c is changed from logic, 〇 > to logic, 1 -, the human interface 槔 5111 is connected to the main port 112 5112, the universal serial bus bar 21 and the universal serial bus keyboard 22 The human interface connection port 5111, the main port 5112, the first universal serial bus master control state 512, and the system controller 521 are sequentially connected. The system controller 521 activates the _general serial bus master controller 512 to initialize the universal serial bus bar. After an authentication process, the universal serial bus bar 21 and the universal serial bus keyboard 22 are established. The universal serial bus bar 21 and the general-column keyboard 22 are managed by the first universal serial bus master controller 512. The system control n 521 obtains an input signal from the universal serial bus bar 21 and the universal serial bus keyboard from the first-general_column main controller 512, and executes an internal mouse decoder 5211 and a keyboard decoding. The body is 5212 and the like, and the action of executing the universal serial bus bar with the universal serial bus keyboard 22 is displayed.

The system controller 521 activates the universal serial bus concentrator 513 to connect the downstream port of the universal serial bus hub 513 to the uplink connection touch signal unit 3 of the general-purpose serial downstream redundancy H 513. In the image signal unit 30, the second (four) bus bar main controller 31 starts the initialization of the money _ stream, and after the __ authentication process, establishes a _ φ ship ride and a pass The link 22 of the keyboard 22 is managed by the second universal serial bus master controller 31 of the image signal unit 30 to manage the string ship (4) and the pass (four) column bus bar keyboard 22. The fifth picture is a schematic diagram of the mode switching. After the working mode is set to the human machine interface, the multimedia unit 53 accepts the application image signal gamma from the function application unit 52, and stacks with the image nickname 3Ga, and makes the wheel The switching unit 51 sends the input of the input unit 2A to the system controller milk of the function application unit 52 for the tiger 2Ga. The image generating unit 52 causes the image generating unit 532 of the multimedia unit 53 to generate a f-single A_in-age unit 40, such as computer A1: currency conversion A2, measurement unit conversion A3, etc., when the human-machine operation interface 522, the screen The H mine 5221 or the input unit 2 () selects the screen display function menu A, and the system controller 521 executes an application corresponding to the application function option. 17 When the mouse keyboard 21 22 is connected to the system controller 521 through the input switching unit 5 ί, 'the user moves the mouse 21 and generates a coordinate signal, which is decoded and sent via the preset mouse decoder 52u in the controller 521. A cursor 211 for the movement of the job mouse a is generated on the unit 4Q of the multimedia unit 53. When the user operates the cursor 211 to select the screen A1 of the function menu A, the system controller 521 extracts the image of the computer image from the core flash memory and sends it to the multimedia element 53. Like generating a single το 532, so that the virtual computer is displayed on the display unit 40 for the user to operate, the user can calculate the number and operator thief on the squirrel 21 _ virtual computer by directly inputting the number and the operation symbol by _ 22 . The functional component 524 of the application unit 52 includes a NAND-type flash memory, a real-time controller circuit, and one or more environmental sensors, so the human-machine interface switching device 50 can provide a clock, a phone book A5, and a note. This A6, and the environment sensing A7 and other functions. To this end, the core flash memory 523 in the function application unit π simultaneously stores an application such as the clock A4, the phone book A5, the notebook Αβ, and the environment sensing Α7 display, and the system controller 521 can access the functional components. 524 application function related information. When the operation mode is once, the system controller 521 displays the control signal 5221 and the input signal 20a of the input unit 21, 22 according to the screen of the man-machine operation interface 522, so that the multimedia unit 53 generates a screen display function menu a displayed on the display unit 40, the screen The function option A can be the clock A4, the phone book A5, the notepad A6, and the environment sensing A7, such as temperature, humidity, and the like. When the clock μ is generated to input the signal to the system controller 521, the system control ^4 5 21 obtains the time information from the instant controller circuit and sends it to the image generation list = 532, so that the display unit 40 generates a time display area. The block shows the time. When the function application material 52 is selected according to the screen display control key 5221 of the man-machine operation interface and the input unit 20, the recording data related to the phone book milk in the screen display function menu a is selected, and the record data related to the phone book milk in the _D type flash memory is The system controller 521 reads and processes it through the multimedia unit 53 and outputs it to the display π early t10. Therefore, the display unit 4Q will display - the phone book for the user to carefully record the previously recorded phone information, such as the above - page, down - page options, or / can also call the phone red _ increase option, and (10) disk ^ type new With the added telephone information, the input signal of the keyboard 22 is decoded by the keyboard decoder 5212 built in the system controller 521 and then output to the image generating unit 532 and stored in the _ type flash memory. The user can return to the on-screen display function menu a to select other functions by simply clicking on the phone to select the phone. When the environmental sensing A7 in the screen display function menu A is selected, such as the temperature generating input signal to the system controller 521, the system controller 521 obtains the environmental sense _ ring thief detector (for example, the temperature is measured The environment (4) (ie, temperature) of the servant is transmitted to the multimedia unit 53 and displayed with the instant temperature on the display unit 40. Similarly, other environmental humidity sensing functions, such as the ambient humidity sensing function, can also be implemented as the human-machine interface switching device 50 (Fig. If there is no indication in the operation mode 1 and the system controller 521 determines that the user moves the cursor 211 to the display unit 4 (the area of the non-screen display function menu A) and clicks, the system controller 521 determines the user. I want to send the input signal 2Ga of the input device 2 to the image signal source unit 3〇 while retaining the currently executed application function. Therefore, the function application unit 52 outputs the image switching signal 52b and the input switching signal 52c. Switching the human-machine interface switching device 5〇 to the working mode 2, so that the input switching unit it 51 connects the input unit 2 and the 22 through the Tongkee busbar hub 32 (not shown) To the image signal unit 3, the input signals of the input units 21, 22 are sent to the image signal unit 30 through the USB hub 32. Since the image signal 3〇a and the image of the application image signal 52a are not displayed at this time. The 兀40 is displayed in a stacked manner, so that when the user inputs an instruction to control the image signal unit 3 through the input units 21, 22, the application function that was originally turned on or in the working mode is continued without being turned off. When the human-machine interface switching device 5 is in the working mode 1, the user switches the mode display A8 with the screen display control button 5221 or the input unit 2 22 screen selection function menu A, and the system controller 521 outputs the image switching. The signal 52b and the input switching signal 52c switch the human-machine interface switching device 5 to the operating state of the working mode 4. At this time, the multimedia unit 53 only accepts the image signal 3〇a from the image signal unit 30, and is processed. Then displayed on the display unit 40. The input switching unit 51 sends the input signal 20a of the input units 21, 22 to the image signal unit 30, so when the user operates the input unit 21 At 22 o'clock, although the input units 21 and 22 are connected to the human-machine interface switching device 50, the input signal is sent to the image signal unit 3 贯. Finally, when the human-machine interface switching device 50 operates at work.
