There are many types, among which the industrial contact tablet PC, which brings together computer technology, network technology, sound planning, ...

Touch screen can be divided into resistive touch screen, capacitive touch screen, surface acoustic wave touch screen, infrared touch screen, optical touch screen according to the type of skill, why do large-size touch all-in-one machines use infrared touch screen? Let's take a look at these different touches one by one. ...

HITECH is a *** in Taiwan, known as Hitech in Chinese mainland. It is the *** of Taiwan Quanyi Electronics Co., Ltd., which was established in 1981 and initially produced electronic watches for pens. In order to transform Quanyi into a technology-oriented company, in 1984 began to develop ...

When the contact screen is connected with the PLC, in fact, the memory of the PLC is used, (the contact screen also has a small amount of memory, which is only used to store system data, that is, the screen, controls, etc.), the contact screen and the PLC communication is generally a master/slave connection, that is, the contact screen reads the data from the PLC, and after making a judgment, it is displayed in the display ...

1. Run your app in full screen Remove the file name bar and menu bar so you can enjoy the benefits of running the entire screen. 2. Choose bright colors (don't use black) The bright color of the set can hide the finger prints, reduce the dazzling light and star...

Industrial tablet PC, that is, industrial all-in-one computer, consists of a contact screen, a display screen, a motherboard, memory, a hard disk, an I/O interface, etc. The scale is generally 8-21 inches, and the wide temperature and wide pressure planning is selected, which can be flexibly used in harsh environments such as temperature and application space, including vehicle-mounted, self-service terminals.

Industrial control automation skills are a kind of comprehensive use of control theory, instrumentation, computer and other information skills to complete detection, control, optimization, scheduling, management and resolution planning of the industrial production process, so as to increase output, improve quality, reduce consumption and ensure safety.

The capacitive skill touch screen uses the current induction of the human body to work. The capacitive contact screen is a four-layer composite glass screen, the inner and outer surface of the glass screen and the interlayer are each coated with a layer of ITO, the outermost layer is a thin layer of silica glass protective layer, the interlayer ITO coating is used as the working surface, and the four corners lead to ...

function For the convenience of operation, people use the touch screen instead of the mouse or keyboard, the touch screen is a smart device that can display and communicate with the PLC, and also has memory and programming capabilities. We can pass ...

1. Four-wire resistive touch screen: It is not afraid of dust, oil and photoelectric disturbance, and is afraid of scratches is its main defect. It is suitable for public places with fixed users, such as industrial control sites, offices, homes, etc.; 2. Five-wire resistive touch screen: Excellent sensitivity and transmittance ...

First, the touch screen response time is very long Problem phenomenon: A contact screen, touch the monitor screen with your fingers, and it takes a long time to react. Problem profiling and processing This could be a touch screen with moving water droplets, just wipe it with a dry, soft cloth ...

Programmable manipulators (PLCs) have always played an important role in industrial field control. With the increase of national investment in the water supply industry, the level of automation of water plant operation has been continuously improved, and the application of PLC in the water supply industry has gradually increased. The touch screen is used with the PLC, so that the operation of the PLC ...

Storage humidity between 10%-90% Temperature -20°C-60°C If the ambient conditions exceed or approach the critical value, condensation will occur inside the display. The power transformer and other coils inside are also prone to leakage when wet, and may even cause a short circuit in the wiring. If you find that the obvious ...

There are two recommended ways to set up the alarm display on the touch screen: 1. Place the alarm window in the template, so that when the alarm occurs, no matter which screen the alarm window is on, it will automatically pop up, so that the operator can obtain the alarm information. ...

Capacitive touch screen is commonly known as "hard screen", such as iPhone and G1 and other machines use this screen quality, resistive touch screen is commonly known as "soft screen", mostly used in Windows Mobile system mobile phones. The capacitive touch screen uses the current induction of the human body to operate, and its contact screen is composed of a four-layer composite glass ...

The light transmittance and clarity of the capacitive contact screen are better than those of the four-wire resistive screen, and of course, it cannot be compared with the external acoustic wave screen and the five-wire resistive screen**. The reflection of the capacitive screen is severe, and the transmittance of the four-layer composite contact screen of the capacitive skill to each wavelength of light is uneven, and there is a problem of color distortion, ...

1. Reporting rate: too fast, the CPU can not respond in time, which may cause drops, and the line is easy to break 2. Accuracy: 99% accuracy 3. Sensitivity: less than two ounces of force can be sensitized, less than 3ms fast response 4. Resolution: with the X, Y axis ...

Embedded device contact screens can be divided into five categories according to their technical principles: vector pressure sensing, resistive, capacitive, infrared, and surface acoustic waves. Among them, resistive contact screens are used more in embedded systems, and resistive contact screens can be divided into four wires, five wires, seven wires and so on. So so...
