Failure and maintenance method of Kunlun Tongtai touch screen

1. Failure regarding touch deviation

If it is the position touched by the finger that does not coincide with the mouse arrow. Then you should install the driver and correct the position without touching the bullseye vertically. and re-correct the position. If some areas are touched accurately, some areas are skewed. It should be caused by the accumulation of a large amount of dust or scale on the sound wave reflection stripes on the four periphery of the Kunlun Tongtai touch screen, which affects the transmission of sound wave signals. And clean the touch screen, pay special attention to clean the sound wave reflection stripes on the four sides of the touch, and disconnect the power supply of the touch screen control card when cleaning.

2. About the fault of the touch that does not respond

If Kunlun Tongtai touches the screen, the mouse arrow does not have any action, and the position does not change. There are many reasons that may cause this phenomenon, and the following is explained one by one: first, the dust or scale accumulated on the sound wave reflection stripes on the four periphery of the surface acoustic touch screen is very serious, causing the touch screen to fail; second, it is the touch screen that fails; Again, it's the touchscreen control card that is faulty; Or maybe the touch screen signal line is faulty or the serial port of the computer host is faulty.

3. Corresponding maintenance methods

The solution is to observe the touch screen signal indicator, the light flashes regularly under normal circumstances, about one flash per second, when touching the screen, the signal light is always on, and after stopping the touch, the signal light resumes flashing. Or if the signal light is still on when it is not touched, first check whether the Kunlun Tongtai touch screen needs to be cleaned; It checks whether the serial slogan connected to the hardware is consistent with the slogan set by the software, and whether the serial port of the computer host is working normally. If none of the above can be solved, then run the COMDUMP command in the drive disk, which is a DOS command, add a space and the code 1 or 2 of the serial port after the COMDUMP when running, and touch the screen to see if there is any data rolled out. If data is rolled out, the hardware connection is normal, check whether the software settings are correct and whether there are conflicts with other hardware devices. If there is no data rollover, the hardware will fail, and the specific fault should be judged and dealt with according to the actual situation.
