Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, a flowchart of an implementation of a control method provided in an embodiment of the present application is shown, where the method may be applied to a display device, such as an android large screen device, an electronic whiteboard, a TV device, a large tablet device, and the like. The technical scheme in the embodiment is mainly used for realizing the control of the display device on the processing device with the data processing function.

Specifically, the method in this embodiment may include the following steps:

step 101: after the processing device is accessed, at least one communication path between the processing device and the processing device is established.

Wherein the communication path is a path for transmitting data between the display device and the processing device.

Specifically, in this embodiment, one or more communication paths between the display device and the processing device may be established in different manners based on different manners of accessing the display device by the processing device.

It should be noted that the processing device in this embodiment may be a device capable of performing data processing, such as Tiny, mainframe box, notebook, computer, or server.

Step 102: and sending the control information to the processing device through at least one communication channel so as to control the processing device to execute the operation corresponding to the control information.

The control information may be information representing different operations, and based on this, after the display device sends the control information to the processing device, the processing device may perform corresponding operations according to the control information, so as to implement control over different functions of the processing device.

Step 103: and displaying and outputting the execution result of the processing equipment.

That is, the execution result of the processing device executing the corresponding operation in accordance with the control information is output on the display device so as to prompt the user of the execution state of the processing device. For example, a storage execution result of a certain item of data stored by a Tiny host is displayed on an android large screen, so that a user is prompted whether the item of data is normally stored.

Wherein the display device and the processing device have the same or different hardware platforms and/or operating systems. For example, the display device may be an ARM platform based device and the processing device is an X86 platform based device, and/or the display device may be an android system configured device and the processing device may be a windows system, MAC system, or linux system configured device.

It should be noted that the processing device is a device having higher processing performance than the display device. For example, the display device can convert the received data into a picture for output, and the processing device can not only convert the data into the picture, but also further process the data or the picture to improve the definition of the picture.

As can be seen from the foregoing solution, in the control method provided in the first embodiment of the present application, after a processing device accesses a display device, by establishing one or more communication paths between the display device and the processing device, the display device may send control information to the processing device, so as to control the processing device to execute a corresponding operation and output an execution result of the processing device on the display device. It can be seen that, in this embodiment, when the processing device accesses the display device, the processing device is controlled on the display device by establishing the communication path, and a control key does not need to be additionally arranged on the display device, thereby reducing the structural complexity between the display device and the processing device.

Further, in this embodiment, the execution result of the processing device may also be output on the display device, so as to prompt the user of the execution state of the processing device in time.

Specifically, when at least one communication path between the processing device and the processing device is established in step 101, the method may be implemented by at least one of the following manners:

in one implementation, in the case that it is detected that the processing device accesses the display device through the first connection device, at least one communication path is established between the processing device and the processing device through the first connection device, where the first connection device may or may not belong to the display device, and the first connection device is capable of supporting communication protocols supported by the processing device and the display device.

For example, the first connection device may be an Open Plug Specification (OPS) conversion module.

Specifically, the first connecting device may be built in the display device and be integrated with the display device, or the first connecting device may be provided separately from the display device and be connected with the display device through a corresponding interface. Also, the first connection means enables conversion of a communication protocol between the processing device and the display device. For example, the OPS conversion module can convert data based on an android large screen communication protocol into data based on a Tiny host machine communication protocol, and can convert data based on the Tiny host machine communication protocol into data based on the android large screen communication protocol, so as to realize data transmission between devices with different communication protocols.

Based on this, in the embodiment, in the case that it is detected that the processing device is connected to the first connection device and the first connection device is built in the display device or is independently connected to the display device, one or more communication paths between the processing device and the display device may be established through the first connection device connected between the display device and the processing device, so as to implement transmission of control information from the display device to the processing device, so that the processing device performs corresponding operations according to the control information.

In another implementation manner, when it is detected that the processing device accesses the display device through the second connection apparatus, at least one communication path between the processing device and the driver corresponding to the target configuration information enumerated by the second connection apparatus is established, where the target configuration information at least can represent communication protocol information supported by the second connection apparatus, and the driver is a driver corresponding to the target configuration information in the processing device and the display device.

For example, the second connecting means may be a Smart cable. The second connection device is connected between the processing device and the display device, and enumerates target configuration information, and represents information of communication protocols that can be supported by the second connection device with the target configuration information, so as to represent the communication protocols that can be supported by the processing device and the display device that can be connected at two ends of the second connection device. Based on this, in this embodiment, one or more communication paths may be established by using the communication protocol supported by the second connection device and using the respective drivers configured for the display device and the processing device connected at both ends, so as to implement transmission of control information from the display device to the processing device, so that the processing device performs corresponding operations according to the control information.

In one implementation, in establishing the communication path in this embodiment, the power mode of the processing device may be determined first, and then a different communication path between the display device and the processing device may be established based on at least the power mode.

That is, the power modes of the processing devices may differ, and the communication paths established accordingly may differ.

Further, in this embodiment, different communication paths between the display device and the processing device may also be established in combination with the control information and the power mode of the processing device.

For example, in the power mode corresponding to the S5 power-off state, in this embodiment, a communication path based on a display interface DP (DisplayPort) may be established, so that after the display device sends control information to the processing device through the DP-based communication path, the processing device can execute a power-on operation according to the control information, such as power-on instruction information;

for another example, in the power mode corresponding to the S0 operating state, in this embodiment, a communication path based on a Universal Serial Bus (USB) or a communication path based on bluetooth may be established in combination with the operation type indicated by the control information, so that after the display device sends the control information to the processing device through the communication path based on USB or bluetooth, the processing device may perform operations such as data interaction according to the control information.

In one implementation, the step 102 of sending the control information to the processing device through at least one communication path may be implemented as follows, as shown in fig. 2:

step 201: a power mode of the processing device is determined.

Specifically, in this embodiment, the power mode of the processing device may be monitored through the communication path, such as the power mode corresponding to the S0 operating state, the power mode corresponding to the S3 sleep state, or the power mode corresponding to the S5 power-off state.

Step 202: it is determined whether the processing device is in the first power mode or the second processing mode and if the processing device is in the first power mode step 203 is performed and if the processing device is in the second power mode step 204 is performed.

Wherein the power consumption of the processing device in the first power mode is less than its power consumption in the second power mode. For example, the first power mode is a power mode corresponding to the S5 power-off state, and the second power mode is a power mode corresponding to the S0 operating state or the S3 sleep state.

Step 203: a first type of control information is transmitted to a processing device over a first communication path.

Step 204: the second type of control information is sent to the processing device over a second communication path.

Wherein the second type is the same as or different from the first type. For example, the first type of control information is information that controls the processing device to perform the first type of operation, and the second type of control is information that newly controls the processing device to perform the second type of operation.

It should be noted that, when the processing device is in different power modes, the processing functions that the processing device can implement are different, and the different processing functions correspond to different control information. For example, the function of the Tiny host (processing device) is different in different power modes, such as that Tiny can provide a storage function in the power-off state, and Tiny can provide a data processing performance in the power-on state. Therefore, in order to avoid the situation of control failure in this embodiment, the power mode in which the processing device is located may be determined first, so as to facilitate transmission of different types of control information, thereby improving the control reliability of the processing device. For example, in a state of Tiny shutdown, if Tiny is needed for data processing, control information for controlling Tiny startup and data processing is sent by an android large screen, and if the control information for controlling Tiny startup is not included, tiny cannot perform data processing operation, and control fails; in the state of Tiny shutdown, if the data storage is required by the Tiny, the android large screen sends control information for controlling the data storage; in a state that the Tiny electronic device is turned on by the Tiny electronic device, the android large screen sends control information for controlling the Tiny electronic device to perform data processing, and the control information for controlling the Tiny electronic device to be turned on by the Tiny electronic device does not need to be sent, so that resource waste of a communication channel is avoided.

Based on the above implementation scheme, when controlling the processing device to execute the operation corresponding to the control information in this embodiment, the following implementation manners may be included:

when the processing device is in the first power mode, the processing device sends a pulse signal, that is, control information of a first type, to the processing device, so that the processing device parses feature information of the pulse signal and executes corresponding operations, where the operations may at least include a power-on operation, and the operations corresponding to different feature information are different.

Specifically, the characteristic information of the pulse signal may include characteristic information such as the number of pulse signals, the width of each pulse signal, and the waveform of each pulse signal.

It should be noted that, in this embodiment, the corresponding relationship between different feature information and the corresponding operation may be configured in advance, and based on this, after the processing device analyzes the feature information of the pulse signal, the processing device may determine the corresponding operation according to the corresponding relationship and execute the operation.

For example, when the processing device is in the S5 power-off state, different characteristic information of the pulse signal sent by the display device corresponds to the operation of normally powering on, and besides, the different characteristic information may correspond to at least one of the following operations: entering Basic Input Output System (BIOS), backup, recovery, fault diagnosis, system diagnosis, BIOS setting, BIOS recovery and the like. Therefore, after the pulse signal is transmitted to the processing device, the processing device can only execute the boot operation, and can further execute one or more operations of BIOS entering, backup, recovery, fault diagnosis, system diagnosis, BIOS setting, BIOS recovery and the like after the boot.

It should be noted that, in this embodiment, when the processing apparatus is in other power modes, the display apparatus also sends the pulse signal, that is, the second type of control information, to the processing apparatus, so that the processing apparatus parses the feature information of the pulse signal and performs corresponding operations, where the operations may at least include data processing operations, such as image sharpness processing, and the like, and the operations corresponding to different feature information are different.

For example, in the S3 sleep state of the processing apparatus, the characteristic information of the pulse signal transmitted by the display apparatus corresponds to an operation of waking up, whereby, after the pulse signal is transmitted to the processing apparatus, the processing apparatus performs the wake-up operation in accordance with the characteristic information of the pulse signal.

It should be noted that, in this embodiment, the control information may also be transmitted through the instruction information, that is, the control information may be implemented as the pulse signal as described above, or may be in other forms of instruction information corresponding to the processing function of the processing device.

Specifically, the method in this embodiment further includes at least one of the following implementation manners:

in one implementation, after the processing device accesses, a part of the tasks of the display device is given to the processing device, so that the processing device can execute the part of the tasks.

Taking the processing device in the first power mode as an example, the display device sends a pulse signal to the processing device, and the processing device executes a power-on operation after analyzing the characteristic information of the pulse signal. After that, the display device transmits control information of partial task execution to the processing device, or adds control information of partial task execution to the pulse signal, so that the processing device executes partial tasks required to be executed for the display device according to the control information, and the rest partial tasks are still executed by the display device, thereby reducing the operation load on the display device by reducing the task execution amount on the display device.

For example, the processing device performs a task of converting partial data into a screen for the display device, the display device performs only a task of converting the remaining partial data into a screen, and the converted screen is transmitted back to the display device after the processing device completes the execution and is displayed by the display device.

In another implementation, after the processing device accesses, all tasks of the display device are given to the processing device, so that the processing device is used to execute the all tasks.

Taking the processing device in the first power mode as an example, the display device sends a pulse signal to the processing device, and the processing device executes a power-on operation after analyzing the characteristic information of the pulse signal. And then, the display device sends control information for executing all tasks to the processing device, or adds the control information for executing all tasks in the pulse signal, so that the processing device executes all tasks required to be executed for the display device according to the control information, the display device does not need to execute the tasks, at the moment, a circuit path or a signal path between the display device and the hardware of the display device can be disconnected, and at least a circuit path and a signal path between a display part of the display device and a software component (including a system and an application) and a hardware component of the processing device are established. Thereby reducing the amount of task execution on the display device to a minimum by applying all tasks to the processing device, thereby reducing the operating load on the display device.

For example, the display device is only used as a screen output device, and the processing device runs an operating system of the display device, implements processing for converting data into a screen, and finally outputs the converted screen on the display device.

In another implementation manner, after the processing device is switched in, the display device is controlled to switch from the first operation mode to the second operation mode, wherein the dependence of the display device on the self-component in the second operation mode is smaller than the dependence of the display device on the self-component in the first operation mode.

Taking the example where the processing device is in the second power mode, the display device sends the pulse signal to the processing device, and the processing device performs a data processing operation after resolving the characteristic information of the pulse signal. Then, the display device reduces the dependence of the currently executed task on the own component according to the generated model switching instruction, thereby reducing the operation load on the display device.

Referring to fig. 3, a flowchart of an implementation of a control method provided in the second embodiment of the present application is shown, where the method may be applied to a processing device capable of performing data processing, such as Tiny, mainframe box, notebook, computer, or server. The technical scheme in the embodiment is mainly used for realizing the control of the display device on the processing device with the data processing function.

Specifically, the method in this embodiment may include the following steps:

step 301: after the target display device is accessed, at least one communication channel with the target display device is established.

The target display device may be a device with a display function, such as an android large screen device, an electronic whiteboard, a TV device, a large-scale tablet device, and the like.

Specifically, the manner of establishing the communication path between the processing device and the target display device may refer to the manner of establishing the communication path in the foregoing, and details are not described here again.

Step 302: receiving control information from a target display device based on at least one communication path;

step 303: responding the control information, and sending a response result to the target display equipment for display and output;

wherein the target display device and the processing device have the same or different hardware platforms and/or operating systems.

Specifically, the processing device may specifically respond to the control information by: the processing device executes corresponding operation according to the control information. The different control information causes the processing device to perform different operations.

It can be known from the foregoing solutions that, in the control method provided in the second embodiment of the present application, after a processing device accesses a display device, by establishing one or more communication paths between the display device and the processing device, the display device may send control information to the processing device, so as to control the processing device to perform a corresponding operation and output an execution result of the processing device on the display device. Therefore, in the embodiment, when the processing device is connected to the display device, the processing device is controlled on the display device by establishing the communication path, and a control key does not need to be additionally arranged on the display device, so that the structural complexity between the display device and the processing device is reduced.

In one implementation manner, when responding to the control information in step 303, the following implementation manner may be specifically implemented:

first, the processing device analyzes characteristic information of the pulse signals, such as the number of the pulse signals, the width of each pulse signal, the waveform of each pulse signal, and the like, in the case of receiving control information transmitted by the target display device through the pulse signals;

and then, the processing equipment executes corresponding response operation based on the characteristic information and sends the response result to the target display equipment for display and output.

The response result may be understood as the execution result in the foregoing, that is, the result generated by the processing device executing the response operation, such as a result of whether the booting is successful, a result of whether the data conversion screen is finished, a result of whether the data storage is finished, and the like.

Specifically, the response operation at least includes a power-on operation, and the response operations corresponding to different feature information are different. For example, the response operation may include any one or more of the following operations based on the difference of the characteristic information: entering BIOS, backup, restoration, fault diagnosis, system diagnosis, BIOS setting, BIOS recovery and the like.

In an implementation manner, in this embodiment, after the processing device enters the first power mode, the BIOS of the processing device may be used to delete the pulse signal stored in the first controller of the processing device.

The first controller may be an embedded controller EC (embedded controller) of the processing device. That is, the processing device may receive and store the pulse signal transmitted from the target display device through the first controller, so that the control processor performs a corresponding response operation according to the characteristic information of the pulse signal in the first controller. After the processing device enters the first power mode, for example, the power mode corresponding to the shutdown state of S5, the BIOS of the processing device clears the pulse signal in the first controller, so that the first controller can continue to receive and store a new pulse signal sent by the target display device when the processing device is in the first power mode next time, thereby implementing accurate device control.

Referring to fig. 4, a schematic structural diagram of a control apparatus according to a third embodiment of the present disclosure is provided, where the apparatus may be configured in a display device, such as an android large screen device, an electronic whiteboard, a TV device, a large tablet device, and the like. The technical scheme in the embodiment is mainly used for realizing the control of the display device on the processing device with the data processing function.

Specifically, the control device in this embodiment may include the following structure:

a path establishing unit 401, configured to establish at least one communication path with a processing device after the processing device is accessed;

an information sending unit 402, configured to send control information to the processing device through the at least one communication path to control the processing device to perform an operation corresponding to the control information;

a result display unit 403 for displaying and outputting the execution result of the processing device;

As can be seen from the foregoing solutions, in the control apparatus provided in the third embodiment of the present application, after a processing device accesses a display device, by establishing one or more communication paths between the display device and the processing device, the display device can send control information to the processing device, so as to control the processing device to perform a corresponding operation and output an execution result of the processing device on the display device. It can be seen that, in this embodiment, when the processing device accesses the display device, the processing device is controlled on the display device by establishing the communication path, and a control key does not need to be additionally arranged on the display device, thereby reducing the structural complexity between the display device and the processing device.

In one implementation, the path establishing unit 401 is specifically configured to:

In one implementation, the path establishing unit 401 is further configured to determine a power mode of the processing device, based on which the path establishing unit 401 establishes a different communication path with the processing device based on at least the power mode.

In one implementation, when sending the control information, the information sending unit 402 is specifically configured to: determining a power mode of the processing device; sending a first type of control information to the processing device over a first communication path if the processing device is in a first power mode; sending a second type of control information to the processing device over a second communication channel if the processing device is in a second power mode; wherein the power consumption of the processing device in the first power mode is less than its power consumption in the second power mode, the second type being the same or different from the first type.

For example, the display device controls the processing device to perform an operation corresponding to the control information, including: and sending a pulse signal to the processing equipment when the processing equipment is in a first power mode, so that the processing equipment analyzes the characteristic information of the pulse signal to execute corresponding operation, wherein the operation at least comprises a starting-up operation, and the operation corresponding to different characteristic information is different.

in one implementation, after a processing device is accessed, a display device gives all tasks of the display device to the processing device, so that the processing device is utilized to execute the all tasks;

in one implementation, after a processing device is switched in, a display device controls the display device to switch from a first operation mode to a second operation mode, wherein dependence of the display device on its own components in the second operation mode is smaller than dependence of the display device on its own components in the first operation mode.

It should be noted that, for the specific implementation of each unit in the present embodiment, reference may be made to the corresponding content in the foregoing first embodiment, and details are not described here.

It can be seen that, in this embodiment, when the processing device accesses the display device, the processing device is controlled on the display device by establishing the communication path, and a control key does not need to be additionally arranged on the display device, thereby reducing the structural complexity between the display device and the processing device.

Taking the processing device as a Tiny host as an example, the following detailed description will be made on the technical solution in the present application:

firstly, an independent Tiny host is changed into an OPS computer module by connecting an OPS (open pluggable standard) switching module, and then the independent Tiny host can be connected to a large screen to be expanded into an intelligent large screen and is used for multiple industries or scenes such as education and business integrated interactive whiteboards. IN order to continue to use the current design of the Tiny machine, the OPS conversion module converts the USB port, DP port and power port (DC IN) on the Tiny back panel into the standard interface of 80PIN which conforms to the OPS specification, connects to the large screen, and acts as a Tiny display through the large screen and supplies power to the OPS Tiny through the large screen. Pin16 of the DP port of Tiny is connected to PWRBTN # of Tiny PCH (Platform Controller Hub), and by pulling this signal low, tiny is turned on, as shown in FIG. 9. The OPS Pin73 PS _ ON is a starting control Pin of an OPS standard, is connected to a DP Pin16 of Tiny through a switching module, the Pin16 of a DP port of Tiny can be connected to a PWRBTN # of Tiny PCH, and a large screen can realize one-key starting of Tiny through pulling down the PS _ ON #.

The method comprises the steps of starting the computer by pressing a power key, entering BIOS SETUP by pressing a hot key in the starting process to modify BIOS setting, starting a diagnostic tool integrated in the BIOS by pressing the hot key in the starting process, selecting starting equipment in the starting process, backing up or restoring a system by counting by pressing the hot key in the starting process, recovering factory settings of the BIOS, and automatically recovering the BIOS when a main BIOS is damaged. Once recovery of the system or BIOS is required, the OPS module is usually removed and the keyboard is inserted to perform related operations. At present, the problem is solved by adopting a mode of configuring a keyboard or arranging functional keys such as a switch on a large screen. But this also causes the complexity of the device to be increased.

Therefore, based ON the technical solution in the present application, the present embodiment proposes that a PIN16 of an existing DP interface ON a back panel of a Tiny host is used to implement a power-ON signal PIN, and an application of the android system ON the smart large screen sends pull-down pulses with a predefined number and width to PS _ ON of the OPS conversion module. As shown in table 1, the correspondence between the number of pulses and the function is:

table 1 correspondence

Number of 50ms pull-down pulses	Function(s)
		1	OPS computer boot
2	OPS computer boot and BIOS SETUP menu
		3	OPS computer boot and system one-key backup
4	OPS computer boot-strap and system one-key restore
		5	OPS computer is started and diagnosis tool is adjusted for diagnosis
6	OPS computer boot and restore factory BIOS settings
		7	OPS computer boot and main BIOS self-recovery

Based ON this, as shown in fig. 10 and fig. 11, APP under the android system of the android large screen sends a falling edge pulse to PS _ ON # (PIN 73) through 80PIN (TX 24), then, the OPS conversion module receives the pulse through DP PIN16 and transmits the pulse to PWRBTN #, EC of the Tiny host captures and records the pulse received by PWRBTN # end, analyzes the number and width of pulse signals, and further determines whether to be a normal boot or enter a BIOS SETUP menu, and performs other functions such as one-key backup or one-key restore, thereby realizing control of Tiny host ON various functions.

Referring to the control flowchart shown in fig. 12:

1. the host computer Tiny system corresponding to the OPS is in an S5 state;

2. the large-screen android system selects to operate an OPS computer through a touch screen, an application program in the large-screen android system sends one or more continuous pull-down pulses to PS _ ON PIN of the OPS within a short time (50 ms), and the number and the width of the pulses both accord with the preset definition;

3. the pulse signals from the large screen are switched through the OPS, one pulse triggers the OPS computer to start, and different pulse numbers trigger different functions after starting.

4. The EC of the Tiny OPS detects the PWRBTN # signal from the S5 state and puts the width and the number of the continuous capture pulses into an EC register; (register will be automatically cleared by EC after the system enters S5)

5. After the host computer is started, the EC continuously monitors and records the number and the width of the pulses, the BIOS of the host computer reads the number of PWRBTN # pull-down pulses from the EC register before the control right is given to the operating system, and the PWRBTN # pull-down pulses are analyzed and loaded with different functions according to the number and the width of the pulses.

In summary, the technical solution of the present application has the following advantages:

1. the current design of a Tiny Tiny host can be directly utilized as an OPS computer module, an interface does not need to be redefined, and extra cost is avoided;

2. the keyboard operation is not needed in the whole process;

3. one or more clear or hidden keys do not need to be designed on the screen shell or the OPS module, so that the operation is convenient, and false triggering can be avoided;

4. more functions can be expanded by different numbers and widths of the sent pull-down pulses.
