Due to technical limitations and poor environmental adaptability, especially the surface acoustic wave screen, the screen cannot be used normally due to water droplets, dust and other pollution, so the touch screen also needs regular maintenance like ordinary machines. And because the touch screen is a highly integrated touch all-in-one machine with a variety of electrical equipment, the following issues should be paid attention to during use and maintenance.
1) Wipe the screen with a dry cloth every day before starting the machine.
2) Water droplets or beverages falling on the screen will cause the software to stop responding. This is because water droplets and fingers have similar characteristics and need to be wiped off.
3) The touch screen controller can automatically determine the dust, but too much dust will reduce the sensitivity of the touch screen, just wipe the screen clean with a dry cloth.
4) Use glass cleaner to clean dirty fingerprints and oil stains on the touch screen.
5) Turn the power on and off in strict accordance with the regulations, that is, the order of turning on the power is: display, audio, and host. Turn off the power in the reverse order.
6) A large number of temporary files are generated on the hard disk. If you frequently break points or simply shut down without exiting Windows, it will quickly cause hard disk errors. Therefore, it is necessary to run scandisk regularly to scan for hard disk errors. It is better to set a secret way in the application to exit the application and to power off the windows, for example: click the four corners in the prescribed order.
7) The pure touch screen program does not need the mouse cursor, the cursor will only make the user's attention distracted.
8) The simplest anti-mouse mode that is sufficient for application should be selected, supported by Siemens S7 200 technology, because complex modes need to sacrifice delay and system resources.
9) In windows, when starting slower applications, users have the opportunity to enter other systems. The solution is to modify the system. ini file: set shell=progman. exe (under windows 3.x) or shell=explorer. exe (on windows95) directly changed to. EXE. But the application should be able to exit windows directly, otherwise the system cannot exit.
10) Depending on the harsh environment, open the machine head regularly to clean the reflective stripes and inner surface of the touch screen. The specific method is: open the cover on both sides of the machine, you can find the mechanism to loosen the lock tongue of the front of the machine head, and open the mechanism to release the lock tongue. Lift the front of the machine head, you can see the touch screen control card, unplug the touch screen cable, move the machine head back to remove the machine head and touch screen. After carefully looking at the method of fixing the touch screen, remove the touch screen and clean it. Be careful not to use hard paper or cloth or scratch the reflective stripes. Finally, restore the nose in the reverse order and the original structure.
