Industrial touch screen computer what problem should note in the design and use

by:Toponetech     2020-03-20
Industrial touch screen computer what problem should note in the design and use. How to correctly use industrial machine is vital for the fuselage life and work smoothly. Accuracy may be defined as in a predefined area of the touch screen large positioning error, to the actual location of the finger with the linear distance between the measurement position for the unit. In the measurement accuracy, use is a simulation or mechanical fingers. Finger placed in the panel on a precise location, put his fingers actual position comparing with measurement location. Accuracy is very important that the user want the system to accurately find the finger position. A resistive touch screens in its faults, is low accuracy, and precision will gradually diminish over time. The accuracy of the capacitive touch screen to create many new applications, such as the virtual keyboard, and no stylus handwritten recognition. Finger spacing: finger spacing is defined as, when the touch screen controller to measure the position of the two fingers, two fingers between the center point of short distance on the screen. Finger distance measurement method, is put two analog or mechanical fingers at panel, and then gradually reduce the distance of two fingers, until the system test to the two fingers for a finger. - - - - - - - - - - - - Relative temperature and relative humidity need to be under the right conditions, while industrial control quality is good, but still should try to avoid moisture, temperature, vibration, dust capacity is much, not smooth desktop and work on the ground. - - - - - - - - - - - - Stable voltage: good to industrial touch screen computer with stabilizer and UPS ac uninterruptible power supply, this not only ensure the stability of voltage and also ensures that won't appear suddenly loses power. To avoid unstable voltage and power loss damage to industrial electronic components. - - - - - - - - - - - - Don't move the removal of industrial computer, if fail, should by professional personnel to solve and troubleshoot. - - - - - - - - - - - - For industrial touch screen computer on a regular basis to clean up, clean the dust cleaning sponge, to ensure the heat dissipation efficiency of the industrial control. In traditional resistive touch panel sensor to finger or stylus, the top layer of flexible transparent material is down, touch the bottom of the conductive material layer; The projected capacitive screen with no moving parts. Relative to the system, the capacitance is fairly small, but can use various techniques to measure the capacitance. Industrial tablet manufacturer also prefer glass screen, because the glass will make the terminal product industrial design with lines and beautiful feeling, and can offer high quality for measuring touch capacitance signal.
