Résoudre le problème des machines de point de vente à écran tactile’ Susceptibilité aux interférences statiques

L'électricité statique peut avoir un impact significatif sur la fonctionnalité des machines de point de vente à écran tactile, entraînant fréquemment des problèmes tels que des sauts d'écran et des désalignements, conduisant à des réponses tactiles inexactes. Ce problème est plus répandu dans les environnements secs sujets à l'électricité statique., surtout lorsque les caissiers manipulent fréquemment des sacs en plastique, générant des charges statiques importantes sur leurs mains. Quand ces mains chargées interagissent avec l'écran, static electricity can infiltrate the POS machine through the touch screen. In minor cases, a simple reboot of the POS machine may rectify the problem. toutefois, in more severe instances, this static electricity can harm touch screen controler or even the entire POS machine.

To address these issues, let’s delve into the operation of capacitive touch screens. These screens consist of a transparent, specialized metal conductor affixed to the glass surface. When a finger comes into contact with this metal layer, it alters the capacitance at the touch point, subsequently modifying the frequency of the connected oscillator. By measuring this frequency shift, the system accurately pinpoints the touch location. Par conséquent, the touch screen’s surface is not only non-insulated but is often finely tuned for high sensitivity to enable precise functionality.

When dealing with a range of customer complaints, Sunany engineers have identified static electricity as the primary culprit behind over 70% of touch screen malfunctions. Sunany always focuses on finding new ways to solve static electricity problems in product research and development, we also want to provide you with suggestions to help you avoid some common static electricity problems::

1. Ensure a stable power supply with proper grounding.

2. Steer clear of potential sources of static electricity, such as an excess of plastic bags.

3. In dry conditions, dissipate static electricity from your hands before using the touch screen. Two effective methods for accomplishing this are either touching an exposed metal component of the cashier station or wiping your hands with a damp cloth.

Even if static electricity results in touch screen problems that cannot be resolved through a simple reboot the POS machine, there is no need for undue concern. Sunany has incorporated protective circuits around the controller, making it resistant to direct damage under normal circumstances. We can provide remote debugging and reprogramming services to address the issue. en outre, we can tailor the firmware to your specific usage environment, adjusting sensitivity settings to meet your requirements.
