So how do we choose the touch screen of the industrial control IPC that we need? You can refer to the following aspects:
1. To purchase an integrated industrial control machine, you need to think about accounting:
There are many brands of touch screen in the domestic market, and there are three grades: high, medium and low. Among them, there are many world-class brands with high quality, and there are also domestic brands with affordable prices.
If you are very concerned about the quotation, the required touch screen is only used as a display, and it is not often used for control input. Then you can choose some domestic brands with lower prices. If you don't have a lot of extra computing, and you often use touch screen input control, you can think about Taiwanese brands with powerful core functions.
2. Purchasing an integrated industrial control machine to recognize the needs:
Generally, some products of international first-line brand touch screens with relatively approachable prices have a narrow scope of application. Generally, they can only be used for products of their own brands, and even some series of products of their own brands cannot adapt to other brands of equipment on the market, so try to choose products with strong adaptability. equipment.
3. Purchase industrial control all-in-one machine to see performance and certification:
See if there are domestic and foreign certifications, it is recommended to try it out or find a special person or equipment to test the performance.
Fourth, the purchase of industrial control integrated machine is more transparent:
Transparency, it directly affects the visual effect of the touch screen. Usually, the transparency can only be the average transparency in the picture. Of course, the higher the better.
Five, choose and buy industrial control all-in-one machine to compare the reflective performance:
Mainly refers to the light and shadow behind the image overlapping on the image due to specular reflection, such as shadows, windows, lights, etc. Reflection is a negative effect brought by the touch screen. The smaller the better, it affects the user's browsing speed. The touch screen is a coordinate system. You can directly click on the one you want to choose. .
Sixth, choose the industrial control integrated machine to see the coordinates:
Its characteristic is that each positioning coordinate has nothing to do with the previous positioning coordinate. The touch screen is a set of independent coordinate positioning system physically, and the data of each touch is converted into the coordinates on the screen through the calibration data. In this way, the touch screen is required to No matter what the set of coordinates is, the output data of the same point is stable. If it is unstable, then the touch screen cannot guarantee the coordinate positioning, and the point is not accurate. This is the most feared problem of the touch screen. Detecting touch and positioning, various touch screens Technologies rely on their own sensors to work, and some touchscreens are even a set of sensors themselves. The respective positioning principles and the respective sensors used determine the response speed, reliability, stability and lifespan of the touch screen.
Only by combining your own needs with the characteristics of the industrial computer, and comparing and contrasting with each other, can you choose the industrial touch screen products that you are satisfied with.
