Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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 invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The resistive touch screen, which is a multi-layer composite film, is formed by a glass or rigid plastic plate as a substrate, coated with a transparent metal oxide (ITO) conductive layer, covered with a hardened, smooth, scratch-resistant plastic layer (the inner surface of which is also coated with an ITO coating), and having a plurality of fine (about 1/1000 inches) transparent spaced dots separating the ITO conductive layers. When a finger touches the screen, two layers of conducting layers which are insulated from each other usually have one contact at a touch point, because one conducting layer is connected with a 5V uniform voltage field in the Y-axis direction, the voltage of a detection layer is changed from zero to nonzero, after the controller detects the connection, A/D conversion is carried out, the obtained voltage value is compared with 5V, and then the Y-axis coordinate of the touch point can be obtained, and the X-axis coordinate can be obtained in the same way.
The resistive touch screen may affect the property of the plastic panel due to external environmental factors (such as strong sunlight, high humidity environment, corrosive air, and the like), which causes the sending change of the resistance value of the measuring resistor, and thus causes the physical coordinate of the tested touch point to change, i.e., the phenomenon of touch drift.
Touch drift is caused because the resistance components of the resistive screen are prone to resistance change, but when the touch drifts, the underlying system can still recognize the occurrence of the touch event and can feed back the touch event to the application program.
The invention provides a touch screen calibration method. Calibration can be performed without power-off restart, and whether touch drift occurs or not can be automatically detected. The method is particularly suitable for industrial control resistance touch screens. Preferably, a separate thread is started for performing the touch screen calibration method.
Fig. 1 is a schematic method diagram of an embodiment of a touch screen calibration method provided by the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the method includes at least step S110, step S120, step S130, and step S140.
Step S110, detecting whether a touch event occurs on the touch screen within a first preset time.
Specifically, after the touch screen is powered on or after a touch event occurs on the touch screen, whether the touch event occurs on the touch screen within a first preset time is detected. For example, the industrial control screen touch screen is powered on to complete function construction (i.e., the program completes initialization), and an independent thread is started for executing touch screen calibration. When the touch panel of the industrial control screen is clicked, the application can read the value of the touch coordinate X, Y. And the independent thread is used, so that the normal operation of the application program is not influenced when the query function is executed. More specifically, after the touch screen is powered on or a touch event occurs on the touch screen, a timer T1 is started, for example, T1 is 180s, and it is determined whether a touch event occurs on the touch screen within time T1.
Step S120, if it is detected that no touch event occurs on the touch screen within a first preset time, displaying a preset touch button, and detecting whether a touch event occurs on the touch screen.
Specifically, if it is detected that no touch event occurs on the touch screen within a first preset time, displaying a preset touch button, and after displaying the preset unlocking button, detecting whether a touch event occurs on the touch screen. Preferably, if it is detected that no touch event occurs on the touch screen within a first preset time, displaying a main interface of the touch screen, and displaying the preset touch button on the main interface, that is, entering a touch drift detection mode. More preferably, when the preset touch button is displayed, first prompt information for performing touch operation on the preset touch button is displayed. Namely, the prompt is used for carrying out touch operation on the preset touch button. More preferably, when the preset touch button is displayed, the display of other touch buttons on the current interface except for the preset touch button is shielded.
The preset touch button is configured to allow a user (user) to touch (e.g., click) the preset touch button before operating the touch screen to determine whether a touch drift occurs. If the touch drift does not occur, the touch screen can be continuously operated. The preset touch button may be specifically an unlock button. For example, if a touch event on the touch screen is detected within the time of T1, the current interface continues to be displayed, and the timer T1 is cleared. If no touch event is detected to be generated on the touch screen within the time T1, the timer T1 is turned off, the main interface is displayed, other interfaces are turned off, the display of other buttons of the main interface is shielded, an unlocking touch button and a reminding character R1 are displayed, and R1 is, for example, "operate the touch screen and click the unlocking button first". And after the unlocking button is displayed, detecting whether a touch event occurs on the touch screen.
Step S130, if it is detected that a touch event occurs on the touch screen, determining whether a touch drift occurs on the touch screen according to a touch coordinate of the touch event.
In a specific embodiment, if it is detected that a touch event occurs on the touch screen, whether a touch drift occurs on the touch screen is determined according to whether a touch coordinate of the touch event occurs in a preset area of the touch screen. Specifically, whether the touch coordinate of the touch event is in a preset area of the touch screen is judged; if the touch coordinate is in the preset area, determining that no touch drift occurs in the touch screen; and if the touch coordinate is not in the preset area, determining that touch drift occurs in the touch screen.
Specifically, the preset area is a preset touch area of the preset touch button. For example, the preset touch button is an unlock button, and the preset area is an unlock button area. If a touch event occurs, reading the value of the touch coordinate X, Y, and determining whether the touch coordinate is in an unlock button area (i.e., a preset area), if the touch coordinate is in the unlock button area, the unlock button and the prompt text disappear, and touch setting and other operations can be performed, and if the touch coordinate is not in the unlock button area, it is determined that touch drift occurs on the touch screen.
Step S140, if it is determined that the touch screen has touch drift, calibrating the touch screen.
In a specific embodiment, if it is determined that the touch screen has touch drift, displaying a second prompt message for entering calibration, and detecting whether a touch event occurs on the touch screen within a second preset time; and if the touch event on the touch screen is detected to occur within a second preset time, entering a preset calibration program to calibrate the touch screen.
For example, if the touch coordinate is not in the unlock button area, it is determined that a touch drift occurs on the touch screen, and a prompt text R2 is displayed, where R2 is, for example, "the touch screen may have touched the drift, please click an arbitrary position to enter calibration", and start a timer T2, for example, T2 is 10 s. And judging whether a touch event occurs within the time of T2, if the touch event does not occur, closing a timer T2, changing the prompt text into R1, if the touch event occurs, executing the next step, entering a calibration program, clicking a screen according to an interface prompt by a user, completing calibration, and automatically reloading the application program.
For clearly illustrating the technical solution of the present invention, the following describes an execution flow of the touch screen calibration method provided by the present invention with a specific embodiment.
Fig. 2 is a schematic diagram of a touch screen calibration method according to an embodiment of the present invention. As shown in fig. 2, the touch screen of the industrial control screen is powered on, the function construction is completed (i.e., the application program is loaded to complete the initialization), an independent thread is started for detecting the touch coordinates and executing the following operations, and when the touch panel of the industrial control screen is clicked, the application program can read the value of the touch coordinates X, Y. And the independent thread is used, so that the normal operation of the application program is not influenced when the query function is executed.
After the industrial control touch screen is powered on or after a touch event occurs, a timer T1 is started, and it is determined whether a touch event occurs within a time period T1, for example, T1 is 180 s. If the touch event occurs within the time T1, the timer T1 is cleared, and the current interface continues to be displayed. If the touch event is not generated within the time T1, the timer T1 is turned off, the main interface is displayed, other interfaces are turned off, the display of other buttons of the main interface is shielded, the unlocking touch button and the reminding text R1 are displayed, and R1 is, for example, "operate the touch screen and click the unlocking button first".
After the unlocking button is displayed, if a touch event occurs, reading the value of the touch coordinate X, Y, judging whether the touch coordinate is in the unlocking button coordinate area, if the touch coordinate is in the unlocking button coordinate area, the unlocking button and the reminding character disappear, touch setting and other operations can be carried out, if the touch coordinate is not in the unlocking button area, executing the next step, and displaying the reminding character R2 and R2, for example, that the touch screen may have touch drift, please click any position to enter calibration. The timer T2 is started, for example, T2 ═ 10 s.
And judging whether a touch event occurs within the time T2, if the touch event does not occur, closing a timer T2, displaying an unlocking button and prompt information R1 on the main interface, and if the touch event occurs, executing the next step. And entering a calibration program, clicking a screen by a user according to an interface prompt to finish calibration, and automatically reloading the application program.
The invention also provides a touch screen calibration device. The calibration can be carried out without power-off and restarting of the unit, and whether touch drift occurs or not can be automatically detected. The device is particularly suitable for industrial control resistance touch screens. Preferably, a separate thread is turned on for performing the function of the touch screen calibration means.

Specifically, the detection unit 110 detects whether a touch event occurs on the touch screen within a first preset time after the touch screen is powered on or after a touch event occurs on the touch screen. For example, the industrial control screen touch screen is powered on to complete function construction (i.e., the program completes initialization), and an independent thread is started for executing touch screen calibration. When the touch panel of the industrial control screen is clicked, the application can read the value of the touch coordinate X, Y. The timer T is started, and the query function is called at regular time to read the touch coordinate X, Y value, for example, T is 0.5s, so that the resources of the memory of the controller can be saved on the premise of not affecting the operation experience by the regular query. And the independent thread is used, so that the normal operation of the application program is not influenced when the query function is executed. More specifically, after the touch screen is powered on or a touch event occurs on the touch screen, a timer T1 is started, for example, T1 is 180s, and it is determined whether a touch event occurs on the touch screen within time T1.
The display unit 120 is configured to display a preset touch button if the detection unit detects that no touch event occurs on the touch screen within a first preset time; the detection unit displays a preset touch button on the display unit to detect whether a touch event occurs on the touch screen.

Preferably, if the detection unit 110 detects that no touch event occurs on the touch screen within a first preset time, the display unit 120 displays a main interface of the touch screen, and displays the preset touch button on the main interface, that is, enters a touch drift detection mode. More preferably, the display unit 120 displays first prompt information for performing touch operation on the preset touch button when the preset touch button is displayed. Namely, the prompt is used for carrying out touch operation on the preset touch button. More preferably, when the preset touch button is displayed, the display unit 120 masks the display of other touch buttons on the current interface except for the preset touch button.
The preset touch button is configured to allow a user (user) to touch (e.g., click) the preset touch button before operating the touch screen to determine whether a touch drift occurs. If the touch drift does not occur, the touch screen can be continuously operated. The preset touch button may be specifically an unlock button. For example, if a touch event on the touch screen is detected within the time of T1, the current interface continues to be displayed, and the timer T1 is cleared. If no touch event is detected to be generated on the touch screen within the time T1, the timer T1 is turned off, the main interface is displayed, other interfaces are turned off, the display of other buttons of the main interface is shielded, an unlocking touch button and a reminding character R1 are displayed, and R1 is, for example, "operate the touch screen and click the unlocking button first". And after the unlocking button is displayed, detecting whether a touch event occurs on the touch screen.
