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 specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise 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 main part of the resistive touch screen is a resistive film screen which is very matched with the surface of the display, and is a multi-layer composite film, wherein a glass or hard plastic flat plate is used as a base layer, the surface of the composite film is coated with a transparent metal oxide (ITO) conductive layer, an outer surface hardening treatment and a smooth scratch-proof plastic layer (the inner surface of the composite film is also coated with an ITO coating), and a plurality of tiny (about 1/1000 inch) transparent spacing points are arranged between the composite film and the transparent plastic layer to separate and insulate the two ITO conductive layers. When a finger touches the screen, two layers of conducting layers which are insulated from each other normally have a contact at the position of a touch point, and one of the conducting layers is connected with a 5V uniform voltage field in the Y-axis direction, so that the voltage of the detection layer is changed from zero to non-zero, after the controller detects the connection, A/D conversion is carried out, the obtained voltage value is compared with 5V, the Y-axis coordinate of the touch point can be obtained, and the X-axis coordinate is obtained in the same way.
The resistance touch screen may affect the properties of the plastic panel due to external environmental factors (such as strong sunlight, high humidity environment, corrosive air, etc.), so that the resistance value of the measurement resistor is changed, and the physical coordinates of the test touch point are changed, namely, the phenomenon of touch drift is caused.
The touch drift can be caused because the resistive element of the resistive screen is easy to generate resistive change, but when the touch drift occurs, the underlying system can still recognize the occurrence of a touch event and can feed back to an application program.
The invention provides a touch screen calibration method. Calibration can be entered without power-off restart and whether touch drift occurs is automatically detected. The method is particularly suitable for industrial control resistance touch screens. Preferably, a separate thread is started for executing the touch screen calibration method.
Fig. 1 is a schematic diagram of a touch screen calibration method according to an embodiment of the present invention.
As shown in fig. 1, the method at least includes step S110, step S120, step S130, and step S140 according to one embodiment of the present invention.
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 a touch event occurs on the touch screen, detecting whether a touch event occurs on the touch screen within a first preset time. For example, an industrial control screen touch screen power-up completes function construction (i.e., program completion initialization), and a separate thread is started for performing touch screen calibration. When the touch panel of the industrial control screen is clicked, the application program can read the value of the touch coordinate X, Y. The independent thread is used, and the normal operation of the application program is not affected when the query function is executed. More specifically, after the touch screen is powered on or after a touch event occurs on the touch screen, a timer T1 is started, for example t1=180 s, and whether a touch event occurs on the touch screen within the time T1 is determined.
Step S120, if it is detected that no touch event occurs on the touch screen within the first preset time, displaying a preset touch button, and detecting whether a touch event occurs on the touch screen.
Specifically, if 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 no touch event occurs on the touch screen within the 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. I.e. prompting the user to perform touch operation on the preset touch button. More preferably, when the preset touch button is displayed, the display of other touch buttons except the preset touch button on the current interface is shielded.
The function of setting the preset touch button is to allow a user to touch the button (e.g., click) before operating the touch screen to determine whether a touch drift occurs. If the touch drift does not occur, the touch screen can be operated continuously. The preset touch button may specifically be an unlocking button. For example, if it is detected that a touch event occurs on the touch screen within the time T1, the current interface is continuously displayed, and the timer T1 is emptied. If no touch event is generated on the touch screen within the time T1, closing the timer T1, displaying the main interface, closing other interfaces, shielding the display of other buttons of the main interface, and displaying the unlocking touch button and reminding words R1, wherein R1 is, for example, "the operation of the touch screen please click the unlocking button first". After the unlocking button is displayed, whether a touch event occurs on the touch screen is detected.
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 the touch coordinates of the touch event.
In a specific embodiment, if it is detected that a touch event occurs on the touch screen, whether the touch drift occurs on the touch screen is determined according to whether the touch coordinates of the touch event are within a preset area of the touch screen. Specifically, judging whether the touch coordinates of the touch event are in a preset area of the touch screen; if the touch coordinate is in the preset area, determining that the touch drift of the touch screen does not occur; and if the touch coordinate is not in the preset area, determining that the touch screen has touch drift.
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, the value of the touch coordinate X, Y is read, whether the touch coordinate is in an unlocking button area (namely a preset area) is judged, if the touch coordinate is in the unlocking button area, the unlocking button and reminding words disappear, touch setting and other operations can be performed, and if the touch coordinate is not in the unlocking button area, the touch drift of the touch screen is determined.
And step S140, if the touch screen is judged to have touch drift, calibrating the touch screen.
In a specific embodiment, if the touch screen is judged to have touch drift, displaying second prompt information for entering calibration, and detecting whether a touch event occurs on the touch screen within a second preset time; if the touch event is detected to occur on the touch screen within the second preset time, entering a preset calibration program, and calibrating the touch screen.
For example, if the touch coordinate is not in the unlock button area, it is determined that the touch screen has touch drift, and the reminding text R2 is displayed, where R2 is, for example, "the touch screen may have touch drift, please click any position to enter calibration", and a timer T2 is started, for example, t2=10s. Judging whether a touch event occurs in the time T2, if no touch event occurs, closing a timer T2, changing prompt characters into R1, if the touch event occurs, executing the next step, entering a calibration program, and completing calibration by clicking a screen according to an interface prompt by a user to automatically reload an application program.
In order to clearly illustrate the technical scheme of the invention, the execution flow of the touch screen calibration method provided by the invention is described in the following by 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 to complete the function construction (i.e. the loading application program completes the initialization), and an independent thread is started to detect the touch coordinates and execute the following operations, when the touch panel of the industrial control screen is clicked, the application program can read the values of the touch coordinates X, Y. The independent thread is used, and the normal operation of the application program is not affected when the query function is executed.
After the industrial control touch screen is powered on or a touch event occurs once, a timer T1 is started, and whether a touch event occurs in the time T1 is judged, for example, T1=180s. If a touch event occurs in the time T1, the timer T1 is cleared, and the current interface is continuously displayed. If no touch event is generated within the time T1, closing the timer T1, displaying the main interface, closing other interfaces, shielding the display of other buttons of the main interface, and displaying the unlocking touch button and the reminding text R1, wherein R1 is, for example, "operating the touch screen to click the unlocking button first".
After the unlocking button is displayed, if a touch event occurs, the value of the touch coordinate X, Y is read, whether the touch coordinate is in the unlocking button coordinate area is judged, if the touch coordinate is in the unlocking button coordinate area, the unlocking button and the reminding text disappear, touch setting and other operations can be performed, and if the touch coordinate is not in the unlocking button area, the next step is executed, and the reminding text R2 and R2 are displayed, for example, the touch screen possibly has touch drift, and the user clicks any position to enter calibration. The timer T2 is started, for example, t2=10s.
Judging whether a touch event occurs in the time T2, if no touch event occurs, closing the timer T2, displaying an unlocking button and prompt information R1 on the main interface, and executing the next step if the touch event occurs. And entering a calibration program, clicking a screen according to the interface prompt by a user, completing calibration, and automatically reloading the application program.
The invention further provides a touch screen calibration device. Calibration can be entered without restarting the machine set after power failure, 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 started for performing the functions of the touch screen calibration device.

Specifically, the detecting 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, an industrial control screen touch screen power-up completes function construction (i.e., program completion initialization), and a separate thread is started for performing touch screen calibration. When the touch panel of the industrial control screen is clicked, the application program can read the value of the touch coordinate X, Y. And starting a timer T, and regularly calling a query function to read the touch coordinate X, Y values, for example, T=0.5 s, wherein the timer query can save the resources of the memory of the controller on the premise of not affecting the operation experience. The independent thread is used, and the normal operation of the application program is not affected when the query function is executed. More specifically, after the touch screen is powered on or after a touch event occurs on the touch screen, a timer T1 is started, for example t1=180 s, and whether a touch event occurs on the touch screen within the time T1 is determined.
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; and the detection unit is used for displaying a preset touch button on the display unit to detect whether a touch event occurs on the touch screen.
Specifically, if the detection unit 110 detects that no touch event occurs on the touch screen within the first preset time, a preset touch button is displayed, and after the preset unlock button is displayed, whether a touch event occurs on the touch screen is detected. Preferably, if the detection unit 110 detects that no touch event occurs on the touch screen within the 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 the first prompt information for performing the touch operation on the preset touch button when displaying the preset touch button. I.e. prompting the user to perform touch operation on the preset touch button. More preferably, the display unit 120 masks the display of other touch buttons except the preset touch button on the current interface when the preset touch button is displayed.
The function of setting the preset touch button is to allow a user to touch the button (e.g., click) before operating the touch screen to determine whether a touch drift occurs. If the touch drift does not occur, the touch screen can be operated continuously. The preset touch button may specifically be an unlocking button. For example, if it is detected that a touch event occurs on the touch screen within the time T1, the current interface is continuously displayed, and the timer T1 is emptied. If no touch event is generated on the touch screen within the time T1, closing the timer T1, displaying the main interface, closing other interfaces, shielding the display of other buttons of the main interface, and displaying the unlocking touch button and reminding words R1, wherein R1 is, for example, "the operation of the touch screen please click the unlocking button first". After the unlocking button is displayed, whether a touch event occurs on the touch screen is detected.
The judging unit 130 is configured to judge whether a touch drift occurs on the touch screen according to the touch coordinates of the touch event if the detecting unit 110 detects that the touch event occurs on the touch screen.
In a specific embodiment, if the detection unit 110 detects that a touch event occurs on the touch screen, it determines whether a touch drift occurs on the touch screen according to whether the touch coordinate of the touch event is within a preset area of the touch screen.
