Detailed Description
The invention aims to provide a method for dynamically detecting and repairing infrared touch by an infrared interaction large screen, which improves the repairing efficiency when the infrared touch is abnormal. In the invention, detection is automatically executed at regular intervals in the interval time when a user uses a large screen touch function, specifically: the Android system end sends a touch detection instruction to the Windows system end; the Windows system starts a touch point acquisition window after receiving the touch detection instruction; then, 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; then, the Windows system end counts 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 feedback from the Windows system end within the set time, the Windows end is informed of closing the acquisition window by the touch program, and the infrared touch frame is reset; if the feedback of the Windows system end is received, corresponding processing is carried out according to the feedback result.
Examples:
the method for dynamically detecting and repairing infrared touch by using the infrared interaction large screen in the embodiment is shown in fig. 1, and comprises the following steps:
s1, an Android system end sends a touch detection instruction to a Windows system end;
in the implementation, in this step, after the Windows is started, a touch detection program is started, and a command input of the Android system end is waited, so as to avoid the influence on the user by using the touch function, the Android system end sends a touch detection instruction to the touch detection program of the Windows system end through a serial port at intervals (which can be set according to the requirement) in a time when the user does not use the touch function.
S2, the Windows system starts a touch point acquisition window after receiving a touch detection instruction;
in the implementation, in this step, after receiving the touch detection instruction, the Windows system starts up 5 virtual touch point acquisition Windows, which are used for respectively and correspondingly acquiring virtual touch point signals of an upper left position, a lower left position, an upper right position, a lower right position and a middle position of the infrared interaction large screen. Because the up-down, left-right and middle positions in the large screen are the most representative, the virtual touch point acquisition can be reflected whether the touch function of the large screen is normal or not by arranging corresponding acquisition windows at the positions, and in view of the fact, the invention is provided with 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 implementation, in this step, the Android system end virtually outputs touch point signals corresponding to the upper left position, the lower left position, the upper right position, the lower right position and the middle position of the infrared interaction large screen, sends the touch point signals to the Windows system end through the infrared touch frame, starts timing, and waits for feedback of the Windows system end.
S4, the Windows system side counts virtual touch points detected by the touch point acquisition window and feeds back the virtual touch points to the Android system side;
in the implementation manner, in this step, the Windows system end determines whether a virtual touch point signal is collected in each virtual touch point collection window, and determines whether an abnormality (such as whether a coordinate point is consistent) occurs in the collected virtual touch point. And then feeding back to the Android system end.
S5, if the Android system end does not receive feedback from the Windows system end within the set time, notifying the Windows end that the touch program closes the acquisition window, and resetting the infrared touch frame; if the feedback of the Windows system end is received, corresponding processing is carried out according to the feedback result.
In the implementation, in the step, if the Android system end does not receive feedback from the Windows system end within a set time, the failure of the touch frame to send the virtual touch point is indicated, and further, the abnormality of the touch frame is judged, and the infrared touch frame needs to be reset; if feedback of the Windows system end is received within the set time, the feedback of the Windows system end is that all the collected virtual touch points are normal, and then the next detection flow is started after a period of time; if the feedback is 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 feedback is that the partial virtual touch point is abnormal, resetting the touch signal.
Based on the design of the dynamic detection flow, the method and the device can quickly locate and repair the touch abnormality.
