Detailed Description
The invention aims to provide a method for dynamically detecting and repairing infrared touch by an infrared interactive large screen, which improves the repairing efficiency when the infrared touch is abnormal. In the invention, in the interval time when the user uses the large screen touch function, the detection is automatically executed at regular intervals, which specifically comprises the following steps: the Android system end sends a touch detection instruction to the Windows system end; the Windows system side starts a touch point acquisition window after receiving a touch detection instruction; then, the Android system end sends a virtual touch point to the Windows system end, starts timing and waits for feedback of the Windows system end; then, the Windows system end counts the virtual touch points detected by the touch point acquisition window and feeds back the virtual touch points to the Android system end; finally, if the Android system end does not receive the feedback of the Windows system end within the set time, the Android system end informs the Windows end touch program to close the acquisition window and reset the infrared touch frame; and if the feedback of the Windows system end is received, performing corresponding processing according to the feedback result.
Example (b):
the method for dynamically detecting and repairing the infrared touch of the infrared interactive large screen in the embodiment is shown in fig. 1, and comprises the following steps:
s1, the Android system side sends a touch detection instruction to the Windows system side;
in the specific implementation, in this step, after the Windows is started, the touch detection program is started, and a command input from the Android system end is waited, so as to avoid an influence on the use of the touch function by the user, the Android system end sends a touch detection instruction to the touch detection program of the Windows system end through the serial port at intervals (which may be set as required) during a period when the touch function is not used by the user.
S2, starting a touch point acquisition window after the Windows system terminal receives the touch detection instruction;
in the specific implementation, in this step, the Windows system starts 5 virtual touch point acquisition Windows after receiving the touch detection instruction, and the Windows system is used for respectively and correspondingly acquiring virtual touch point signals at the upper left position, the lower left position, the upper right position, the lower right position and the middle position of the infrared interactive large screen. Because the upper, lower, left, right and middle positions in the large screen are most representative, setting corresponding acquisition windows at the positions to perform virtual touch point acquisition can reflect whether the touch function of the large screen is normal or not, and in view of the fact, the invention sets the 5 virtual touch point acquisition windows.
S3, the Android system end sends the virtual touch point to the Windows system end, starts timing and waits for feedback of the Windows system end;
in the specific implementation, in this step, the Android system end virtualizes touch point signals corresponding to an upper left position, a lower left position, an upper right position, a lower right position, and a middle position of the infrared interactive large screen, sends the touch point signals to the Windows system end through the infrared touch frame, and starts timing to wait for feedback of the Windows system end.
S4, the Windows system side counts the virtual touch points detected by the touch point acquisition window and feeds back the virtual touch points to the Android system side;
in this step, the Windows system determines whether a virtual touch point signal is collected in each virtual touch point collection window, and determines whether the collected virtual touch points are abnormal (for example, whether coordinate points are consistent). And then feeding back to the Android system terminal.
S5, if the Android system end does not receive the feedback of the Windows system end within the set time, informing the Windows end touch program to close the acquisition window, and resetting the infrared touch frame; and if the feedback of the Windows system end is received, performing corresponding processing according to the feedback result.
In the specific implementation, in this step, if the Android system end does not receive the feedback of the Windows system end within the set time, it is indicated that the touch frame fails to send the virtual touch point, and it is further determined that the touch frame is abnormal and the infrared touch frame needs to be reset; if the feedback of the Windows system end is received within the set time, and the feedback of the Windows system end is that the collected virtual touch points are all normal, starting the next detection process after a period of time; if the feedback indicates that all the virtual touch points are abnormal, reconfiguring parameters (such as mirror images, offset and the like) of the infrared touch frame; and if the fed back part of the virtual touch points is abnormal, resetting the touch signal.
Based on the design of the dynamic detection process, the method can quickly locate and repair the abnormal touch.
