The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
The embodiment aims to provide a BIOS control method and system based on a touch screen and a touch screen control panel, which are used for solving the problem that the BIOS cannot be modified when no physical keyboard is available in the prior art.
The BIOS control method and system based on the touch screen and the touch screen control board of the embodiment utilize the touch screen control board to send simulated keyboard signals to a system CPU so as to achieve the purpose of controlling and modifying the BIOS.
The principle and the implementation of the BIOS control method, system and touch screen control board based on the touch screen of the present embodiment will be described in detail below, so that those skilled in the art can understand the BIOS control method, system and touch screen control board based on the touch screen without creative labor.
Example 1
As shown in fig. 1, the present embodiment provides a BIOS control method based on a touch screen, which is applied to a touch screen control board and at least includes:
step S100: reading touch operation input to a preset touch area of a touch screen within the initial time of electrifying a control panel of the touch screen, and sending an entering key message simulating an entering key to a BIOS system to enter the BIOS system when the touch operation is read;
step S200: when a response of the BIOS system is received, detecting touch operation input to the touch screen, converting the touch operation into a corresponding simulation key input message, and sending the simulation key input message to the BIOS system;
step S300: and when a response of an operating system is received, detecting 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.
The following describes steps S100 to S300 of the BIOS control method based on the touch screen in this embodiment in detail.
Step S100: the method comprises the steps of reading touch operation input to a preset touch area of a touch screen within the initial time of electrifying a control panel of the touch screen, and sending an entering key message simulating an entering key to a BIOS system to enter the BIOS system when the touch operation is read.
The working principle of the touch screen control plate is that touch data of the touch screen is read through a physical interface, and then the touch data is reported from a USB interface in an HID interface mode or an MOUSE interface mode. The HID interface can report messages of a mouse and a keyboard at the same time, so that the touch screen control panel can be used as a physical keyboard and a touch screen to report to a BIOS system after receiving a specified touch effect within a few seconds after being electrified for the first time.
In this embodiment, the enter key message is sent to the BIOS system through the USB-HID interface of the touch screen.
Specifically, in this embodiment, one specific implementation manner of sending the key message simulating the entry key to the BIOS includes:
the number of the simulation entry keys is multiple, and each simulation entry key is sent to the BIOS system in an alternating cycle.
The method comprises the steps that touch operation input to a preset touch area of a touch screen is read in the initial time of electrifying a control board of the touch screen, and a plurality of simulated entry keys are sent to a BIOS system in an alternate circulation mode when the touch operation is read.
In this embodiment, the method for entering the BIOS system by alternately and cyclically sending the plurality of simulated entry buttons to the BIOS system is a method for entering the BIOS system by simulating the physical buttons, in which the plurality of simulated entry buttons are sent to the BIOS system as if the computer is started, but the method generally includes pressing 3 buttons of the Del button, the F2 button, and the F10 button back and forth when it is unknown what button is pressed.
The step of sending the plurality of simulated entry keys to the BIOS system in an alternating cycle does not limit the order of each simulated entry key, the step of sending the plurality of simulated entry keys to the BIOS system in an alternating cycle may be performed according to a preset order of each simulated entry key, or the step of sending the plurality of simulated entry keys to the BIOS system in an alternating cycle in a random manner.
Wherein, the analog enter key is preferably but not limited to a Del key, an F2 key, an F10 key, etc.
The initial time is 3 s-10 s, for example, within 3s of electrifying a control board of the touch screen, sending a Del key, an F2 key and an F10 key to the BIOS system in an alternating cycle.
For example, the Del button, the F2 button and the F10 button are alternately sent, one is sent after 1 second, the next is sent after the completion of sending, and the sending is cycled to enter the BIOS system.
Step S200: and when a response of the BIOS system is received, detecting the touch operation input to the touch screen, converting the touch operation into a corresponding simulation key input message, and sending the simulation key input message to the BIOS system.
When the information reported by the USB interface of the touch screen is received by the BIOS system response, the touch operation can simulate the input of the physical keyboard according to a certain rule so as to achieve the purpose of modifying the BIOS function.
Specifically, in this embodiment, as shown in fig. 2, one specific implementation manner of converting the touch operation into the corresponding simulated key input message includes:
step S210: the type and the operation area of the touch operation are detected.
In this embodiment, the touch screen is divided into a plurality of operation areas; each operation area corresponds to at least one type of touch operation; one simulation key corresponds to one operation area and one type of touch operation of the operation area.
Specifically, in this embodiment, a preferred manner of dividing the touch screen is, but not limited to, nine operation areas, and the nine operation areas are distributed in a squared figure. For example, the touch screen may be divided into six operation areas, and the six operation areas are distributed in two rows, one being at the top and the other being at the bottom.
In this embodiment, the types of the touch operations include, but are not limited to, a single touch, a two-point touch, and a sliding touch in a predetermined direction.
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.
In one embodiment, for example, one operation area corresponds to a single-point touch type of touch operation, and the other operation area corresponds to a double-point touch type of touch operation. Each operation area may be configured with a type of a corresponding touch operation.
In another embodiment, for example, one operation area corresponds to two types of touch operations, namely single-point touch and two-point touch, and the other operation area corresponds to two types of touch operations, namely single-point touch and sliding touch in a preset direction.
In another embodiment, for example, one operation area corresponds to three types of touch operations, i.e., a single-point touch, a two-point touch, and a sliding touch in a preset direction, and the other operation area corresponds to two types of touch operations, i.e., a single-point touch and a sliding touch in a preset direction.
Therefore, in this embodiment, the type of touch operation configured for each operation area may be flexibly configured and defined.
When a touch operation by a user is detected, the type and operation area of the touch operation are detected.
Specifically, the process of detecting the type and the operation area of the touch operation is as follows:
after a touch screen control board is electrified, firstly reading the size of the touch screen, namely the length and the width of the touch screen, and forming a size coordinate of the touch screen;
reading touch data input to the touch screen in real time, and judging the type of touch operation of the touch data according to the number, duration or pressing length of received touch signals, such as single-point touch data, double-point touch data or sliding touch in a preset direction;
and reading a touch coordinate corresponding to the touch data, and calculating an operation area of the touch data on the touch screen according to the touch coordinate and the size coordinate of the touch screen, thereby completing the detection of the type and the operation area of the touch operation.
Step S220: acquiring a simulation key corresponding to the type and the operation area of the detected touch operation according to a preset mapping table; the mapping table comprises corresponding relations between different types of touch operation, different operation areas and the simulation keys.
Dividing the touch screen range into 9 parts according to the nine-square grid, dividing the touch screen range into 9 operation areas, and simulating corresponding keyboard input messages according to different touch operation types of the 9 operation areas. Wherein, the types of the 9 touch operations may be respectively named as [ upper left ], [ middle left ], [ lower left ], [ middle upper ], [ center ], [ lower middle ], [ upper right ], [ middle right ], [ lower right ]. An example of the mapping table established is shown in table 1.
The corresponding relation between the touch behavior of the mapping table and the simulated key can be customized.
The method comprises the steps of collecting touch data of a user, detecting the type and the operation area of corresponding touch operation according to the touch data, and then obtaining a simulation key corresponding to the type and the operation area of the detected touch operation according to a mapping table.
Step S230: and generating an analog key input message corresponding to the analog key according to the acquired analog key.
And the simulation key input message is sent to the BIOS system through a USB-HID interface of the touch screen.
Step S300: and when a response of an operating system is received, detecting 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.
That is, when the USB-HID interface of the touch screen receives the BIOS response, the touch data may be used to simulate the keyboard input according to a certain rule, so that the purpose of modifying the BIOS by the keyboard input can be achieved by using the touch screen control interface when there is no physical keyboard. When the USB-HID interface receives the response of the computer operating system (Linux/Windows/Mac and the like), the function of simulating keyboard input is closed, and only normal touch information of the touch screen is reported.
