[0002] BIOS (Basic Input Output System) is a set of programs that are fixed to a ROM chip on the motherboard of the computer. It stores the most important basic input and output programs of the computer, the self-test program after power-on, and the system self-starting program. It can read and write specific information of system settings from CMOS. The main function of BIOS is to provide the lowest-level and most direct hardware settings and control for the computer. In addition, BIOS also provides some system parameters to the operating system.

[0036] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0037] The purpose of this embodiment is to provide a touch screen-based BIOS control method, system and touch screen control panel, which are used to solve the problem in the prior art that the BIOS cannot be modified when there is no physical keyboard.

[0038] The touch screen-based BIOS control method, system and touch screen control panel of this embodiment utilize the touch screen control panel to send simulated keyboard signals to the system CPU to achieve the purpose of controlling and modifying the BIOS.

[0039] The principles and implementation methods of the touch screen-based BIOS control method, system and touch screen control panel of this embodiment will be described in detail below, so that those skilled in the art can understand the touch screen-based BIOS control method, system and touch screen control panel of the present invention without creative work.

[0040] Example 1

[0041] like Figure 1As shown, this embodiment provides a touch screen-based BIOS control method, which is applied to a touch screen control panel and at least includes:

[0042] Step S100: reading a touch operation input to a preset touch area of ​​the touch screen within an initial time after the control board of the touch screen is powered on, and sending an enter key message simulating an enter key to the BIOS system when the touch operation is read, so as to enter the BIOS system;

[0043] Step S200: upon receiving a response from the BIOS system, detecting a touch operation input to the touch screen and converting the touch operation into a corresponding simulated key input message, and sending the simulated key input message to the BIOS system;

[0044] Step S300: upon receiving a response from the operating system, detecting a touch operation input to the touch screen, generating a corresponding touch message according to the touch operation, and sending the touch message to the operating system.

[0045] The following is a detailed description of steps S100 to S300 of the touch screen-based BIOS control method of this embodiment.

[0046] Step S100: within the initial time when the control board of the touch screen is powered on, read the touch operation input to the preset touch area of ​​the touch screen, and when the touch operation is read, send an enter key message simulating an enter key to the BIOS system to enter the BIOS system.

[0047] The working principle of the touch screen control board is to read the touch data of the touch screen through the physical interface, and then report the touch data from the USB interface in the form of HID interface or MOUSE interface. The HID interface can report mouse and keyboard messages at the same time, so the touch screen control board can report the touch screen control board itself as a physical keyboard and touch screen to the BIOS system within a few seconds after the first power-on, after receiving the specified touch effect.

[0048] In this embodiment, the entry key message is sent to the BIOS system through the USB-HID interface of the touch screen.

[0049] Specifically, in this embodiment, a specific implementation method of sending a key message simulating an enter key to the BIOS system includes:

[0050] There are multiple simulated entry buttons, and each of the simulated entry buttons is sent to the BIOS system in an alternating cycle.

[0051] That is, within the initial time when the control board of the touch screen is powered on, the touch operation input to the preset touch area of ​​the touch screen is read, and when the touch operation is read, multiple simulated entry keys are sent to the BIOS system in an alternating cycle.

[0052] Sending multiple simulated entry keys to the BIOS system in an alternating cycle is like when you want to enter the BIOS system when you start up your computer, but you don't know which key to press, so generally you press the Del key, F2 key, and F10 key back and forth. In this embodiment, sending multiple simulated entry keys to the BIOS system in an alternating cycle is a way of simulating the above-mentioned physical keys to enter the BIOS system.

[0053] The order of the simulated entry keys is not limited in the alternating cycle of sending multiple simulated entry keys to the BIOS system. The multiple simulated entry keys can be sent to the BIOS system in an alternating cycle according to a preset order of the simulated entry keys, or in a random manner.

[0054] The simulated entry key is preferably but not limited to a Del key, an F2 key, an F10 key, etc.

[0055] The initial time is 3s to 10s. For example, within 3s after the control board of the touch screen is powered on, the Del key, the F2 key, and the F10 key are sent to the BIOS system in an alternating cycle.

[0056] For example, the Del key, the F2 key, and the F10 key are sent alternately, one every second, and the next one is sent after each one is sent, in a cycle to enter the BIOS system.

[0057] Step S200: upon receiving a response from the BIOS system, detecting a touch operation input to the touch screen and converting the touch operation into a corresponding simulated key input message, and sending the simulated key input message to the BIOS system.

[0058] When the USB interface of the touch screen reports device information and receives a BIOS system response, the touch operation can be simulated with a certain rule to simulate a physical keyboard input, so as to achieve the purpose of modifying the BIOS function.

[0059] Specifically, in this embodiment, if Figure 2 As shown, a specific implementation method of converting the touch operation into a corresponding simulated key input message includes:

[0060] Step S210: Detecting the type and operation area of ​​the touch operation.

[0061] In this embodiment, the touch screen is divided into a plurality of operation areas; each of the operation areas corresponds to at least one type of touch operation; and one simulation button corresponds to one operation area and one type of touch operation of the operation area.

[0062] Specifically, in this embodiment, a preferred way of dividing the touch screen is, but not limited to, nine operation areas, which are arranged in a nine-square grid. For example, the touch screen can also be divided into six operation areas, which are arranged in two rows, three in each row.

[0063] In this embodiment, the types of touch operations include but are not limited to single-point touch, two-point touch, and sliding touch in a preset direction.

[0064] Each of the operation areas corresponds to at least one type of touch operation, that is, one operation area may correspond to one type of touch operation, or may correspond to two or more types of touch operations.

[0065] In one embodiment, for example, one operation area corresponds to a touch operation type of single-point touch, and another operation area corresponds to a touch operation type of double-point touch. Each operation area can be configured with a corresponding touch operation type.

[0066] In another embodiment, for example, one operation area corresponds to two types of touch operations: single-point touch and two-point touch, and another operation area corresponds to two types of touch operations: single-point touch and sliding touch in a preset direction.

[0067] In another embodiment, for example, one operation area corresponds to three types of touch operations: single-point touch, two-point touch, and sliding touch in a preset direction, and another operation area corresponds to two types of touch operations: single-point touch and sliding touch in a preset direction.

[0068] Therefore, in this embodiment, the type of touch operation configured in each operation area can be flexibly configured and defined.

[0069] When a touch operation by the user is detected, the type of the touch operation and the operation area are detected.

[0070] Specifically, the process of detecting the type of touch operation and the operation area is as follows:

[0071] After the touch screen control board is powered on, it first reads the size of the touch screen, that is, the length and width of the touch screen, to form the size coordinates of the touch screen;

[0072] Reading touch data input to the touch screen in real time, and determining the type of touch operation of the touch data according to the number of touch signals received, the duration or the pressing length, such as single-point touch data, double-point touch data or sliding touch in a preset direction;

[0073] The touch coordinates corresponding to the touch data are read, and the operation area of ​​the touch screen where the touch data is located is calculated through the touch coordinates and the size coordinates of the touch screen, thereby completing the detection of the type of touch operation and the operation area.

[0074] Step S220: acquiring the simulated key corresponding to the detected touch operation type and operation area according to a pre-configured mapping table; the mapping table includes the correspondence between different types of touch operations, different operation areas and each simulated key.

[0075] The touch screen range is divided into 9 parts according to the nine-square grid, which are divided into 9 operation areas, and then the corresponding keyboard input messages are simulated according to the types of different touch operations in the 9 operation areas. Among them, the 9 touch operation types can be named [upper left], [middle left], [lower left], [upper middle], [center], [lower middle], [upper right], [middle right], [lower right] respectively. An example of the established mapping table is shown in Table 1.

[0076]

[0077]

[0078] The corresponding relationship between the touch behaviors and the simulated keys in the above mapping table can be customized.

[0079] The user's touch data is collected, the type of touch operation and the operation area corresponding to the touch data are detected, and then the simulated key corresponding to the detected type of touch operation and the operation area is obtained according to the mapping table.

[0080] Step S230: Generate a simulated key input message corresponding to the simulated key according to the acquired simulated key.

[0081] The simulated key input message is sent to the BIOS system through the USB-HID interface of the touch screen.

[0082] Step S300: upon receiving a response from the operating system, detecting a touch operation input to the touch screen, generating a corresponding touch message according to the touch operation, and sending the touch message to the operating system.

[0083] That is to say, when the touch screen's USB-HID interface receives a BIOS response, the touch data can be simulated as keyboard input according to certain rules, so that when there is no physical keyboard, the touch screen control interface can be used to modify the BIOS by keyboard input. When the USB-HID interface receives a computer operating system response (Linux / Windows / Mac, etc.), the keyboard input simulation function is turned off, and only normal touch screen touch messages are reported.

[0084] Example 2

[0085] like Figure 3 As shown, this embodiment provides a touch screen-based BIOS control system 100 , and the touch screen-based BIOS control system 100 includes: an entry module 110 , a BIOS system interaction module 120 and an operating system interaction module 130 .

[0086] In this embodiment, the entry module 110 is used to receive a touch operation input to a preset touch area of ​​the touch screen within the initial time when the control board of the touch screen is powered on, and upon receiving the touch operation, sends an entry key message simulating an entry key to the BIOS system to enter the BIOS system.

[0087] In this embodiment, the entry key message is sent to the BIOS system via the USB-HID interface of the touch screen.

[0088] Specifically, in this embodiment, a specific implementation manner of the entry module 110 sending a key message simulating an entry key to the BIOS system includes:

[0089] There are multiple simulated entry buttons, and each of the simulated entry buttons is sent to the BIOS system in an alternating cycle.

[0090] That is, within the initial time when the control board of the touch screen is powered on, the touch operation input to the preset touch area of ​​the touch screen is read, and when the touch operation is read, multiple simulated entry keys are sent to the BIOS system in an alternating cycle.

[0091] Sending multiple simulated entry keys to the BIOS system in an alternating cycle is like when you want to enter the BIOS system when you start up your computer, but you don't know which key to press, so generally you press the Del key, F2 key, and F10 key back and forth. In this embodiment, sending multiple simulated entry keys to the BIOS system in an alternating cycle is a way of simulating the above-mentioned physical keys to enter the BIOS system.

[0092] The order of the simulated entry keys is not limited in the alternating cycle of sending multiple simulated entry keys to the BIOS system. The multiple simulated entry keys can be sent to the BIOS system in an alternating cycle according to a preset order of the simulated entry keys, or in a random manner.

[0093] The simulated entry key is preferably but not limited to a Del key, an F2 key, an F10 key, etc.

[0094] The initial time is 3s to 10s. For example, within 3s after the control board of the touch screen is powered on, the Del key, the F2 key, and the F10 key are sent to the BIOS system in an alternating cycle.

[0095] For example, the Del key, the F2 key, and the F10 key are sent alternately, one every second, and the next one is sent after each one is sent, in a cycle to enter the BIOS system.

[0096] In this embodiment, the BIOS system interaction module 120 is used to detect a touch operation input to the touch screen and convert the touch operation into a corresponding simulated key input message when receiving a response from the BIOS system, and send the simulated key input message to the BIOS system.

[0097] When the USB interface of the touch screen reports device information and receives a BIOS system response, the touch operation can be simulated with a certain rule to simulate a physical keyboard input, so as to achieve the purpose of modifying the BIOS function.

[0098] Specifically, in this embodiment, if Figure 4 As shown, the BIOS system interaction module 120 includes: a detection unit 121, a simulated key acquisition unit 122, a key message generation unit 123 and a message sending unit 124.

[0099] In this embodiment, the detection unit 121 is used to detect the type and operation area of ​​the touch operation.

[0100] In this embodiment, the touch screen is divided into a plurality of operation areas; each of the operation areas corresponds to at least one type of touch operation; and one simulation button corresponds to one operation area and one type of touch operation of the operation area.

[0101] Specifically, in this embodiment, a preferred way of dividing the touch screen is, but not limited to, nine operation areas, which are arranged in a nine-square grid. For example, the touch screen can also be divided into six operation areas, which are arranged in two rows, three in each row.

[0102] In this embodiment, the types of touch operations include but are not limited to single-point touch, two-point touch, and sliding touch in a preset direction.

[0103] Each of the operation areas corresponds to at least one type of touch operation, that is, one operation area may correspond to one type of touch operation, or may correspond to two or more types of touch operations.

[0104] In one embodiment, for example, one operation area corresponds to a touch operation type of single-point touch, and another operation area corresponds to a touch operation type of double-point touch. Each operation area can be configured with a corresponding touch operation type.

[0105] In another embodiment, for example, one operation area corresponds to two types of touch operations: single-point touch and two-point touch, and another operation area corresponds to two types of touch operations: single-point touch and sliding touch in a preset direction.

[0106] In another embodiment, for example, one operation area corresponds to three types of touch operations: single-point touch, two-point touch, and sliding touch in a preset direction, and another operation area corresponds to two types of touch operations: single-point touch and sliding touch in a preset direction.

[0107] Therefore, in this embodiment, the type of touch operation configured in each operation area can be flexibly configured and defined.

[0108] When a touch operation by the user is detected, the type of the touch operation and the operation area are detected.

[0109] In this embodiment, the simulated key acquisition unit 122 is used to acquire the simulated key corresponding to the type of touch operation and the operation area detected according to a preconfigured mapping table; the mapping table includes the correspondence between different types of touch operations, different operation areas and each simulated key.

[0110] An example of the established mapping table is shown in Table 1 in Embodiment 1. This embodiment will not be described in detail.

[0111] The user's touch data is collected, the type of touch operation and the operation area corresponding to the touch data are detected, and then the simulated key corresponding to the detected type of touch operation and the operation area is obtained according to the mapping table.

[0112] In this embodiment, the key message generating unit 123 is used to generate a simulated key input message corresponding to the simulated key according to the acquired simulated key.

[0113] In this embodiment, the message sending unit 124 is used to send the simulated key input message to the BIOS system.

[0114] The simulated key input message is sent to the BIOS system through the USB-HID interface of the touch screen.

[0115] In this embodiment, the operating system interaction module 130 is used to detect a touch operation input to the touch screen and generate a corresponding touch message according to the touch operation when receiving a response from the operating system, and send the touch message to the operating system.

[0116] That is to say, when the touch screen's USB-HID interface receives a BIOS response, the touch data can be simulated as keyboard input according to certain rules, so that when there is no physical keyboard, the touch screen control interface can be used to modify the BIOS by keyboard input. When the USB-HID interface receives a computer operating system response (Linux / Windows / Mac, etc.), the keyboard input simulation function is turned off, and only normal touch screen touch messages are reported.

[0117] The technical features specifically implemented by the touch screen-based BIOS control system 100 of this embodiment are substantially the same as those of the touch screen-based BIOS control method in the aforementioned embodiment, and the technical contents that are common between the embodiments will not be repeated.
