As the manufacturers of the industrial touch all-in-one machine are mixed with fish and the quality varies from good to bad, the phenomenon of brand mixing is very serious. To this end, I have compiled the following five points for reference, and hope to help everyone.
1. Choose the LCD screen carefully
The quality of the LCD screen directly affects the overall effect and experience of an industrial touch all-in-one machine, so a good industrial touch all-in-one machine must use a high-specification LCD screen as the core hardware of the whole machine. Take the industrial touch all-in-one machine produced by Shenzhen Zhixiang intelligent production as an example. The LCD screen used is from Taiwan’s Industrial Control A Regulation, which is the basic point of choosing an LCD screen.
2. Pay attention to touch technology: The mainstream touch methods of touch screens on the market are divided into resistive touch screens, capacitive touch screens, and infrared touch screens.
The characteristic of the resistive touch screen is that its working environment is completely isolated from the outside world, and it is not afraid of dust, moisture and oil. It can be manipulated by the touch of any object. It is relatively suitable for use in industrial fields with poor working environment. The disadvantage is that because the outer construction material of the composite film is plastic, too much force or using a sharp object will scratch the touch screen.
Capacitive touch screen features: very high resolution and good light transmittance. It can well meet various requirements. At present, this kind of touch screen is common in public places. The disadvantage is that the capacitive touch screen requires the human body to act as an electrode of the capacitor, and once a conductor approaches and couples a certain amount of capacitance with the working surface of the mezzanine, the flowing current will cause the capacitive touch screen to malfunction. ; In addition, if you wear gloves or touch with an insulating object, the capacitive touch screen cannot respond, because the insulating medium cannot make the capacitive screen generate an operating current.
Infrared touch screen: The touch position is determined by measuring the on-off state of infrared rays, and is not affected by the material of the bezel selected for the touch screen (some infrared touch screens do not use the bezel at all). Therefore, try to choose a baffle with good light transmittance as much as possible, and at the same time carry out anti-reflective treatment, you will get a very good visual effect. However, due to the limitation of the volume of the infrared emitting tube, it is difficult to emit high-density infrared light beams, which results in the low resolution of such a touch screen. In addition, since the infrared touch screen relies on infrared sensing to respond to operations, changes in external light, such as sunlight or indoor lights, will affect its sensitivity and accuracy.
Three, the host configuration depends on your choice
The host configuration of the industrial all-in-one machine is not much different from the configuration of common computers. It is basically composed of several main sections such as the motherboard, CPU, memory and hard disk. In addition, the configuration of the industrial all-in-one machine can be selected according to your own needs, and try to buy it directly from the manufacturer. They have advantages in hardware technology and personalized customized solutions, and are easier to operate.
Four, the more functional applications, the better
The industrial touch all-in-one machine integrates the functions of TV, computer and monitor, and it uses touch operation to replace the mouse and keyboard. Basically the functions that the computer can achieve, the industrial touch all-in-one machine can do it. The touch industrial all-in-one machine is matched with different types of functions. Touch software can also achieve more functions, and it can be applied to scientific research and teaching, shopping mall display, conference training, and self-service terminal information query without any problems.
5. Machine selection should be based on specific application requirements
There are many sizes of industrial touch screens, from 8 inches to 23 inches. I don't know how to choose the size when purchasing. Here is how to choose. Generally speaking, self-service terminals are mainly used for human-computer interaction and are mainly used for inquiries, and the size does not need to be too large. It depends on what size you want and what configuration requirements are needed. Different sizes and configurations have different prices.
In addition to the above five points that need to be paid attention to when purchasing an industrial touch all-in-one machine, there is also a more important factor, that is, the brand. A good brand can not only guarantee the quality of the product, but also guarantee perfect after-sales service. Let you have no worries after purchasing the machine.
