Basic functions and selection indicators of human-machine interface

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, ...

The contact screen, simply put, is the combination of input and output, no longer need mechanical buttons or sliders, the display screen is a human-machine interface. The whole contact screen module is composed of LCD, contact screen, contact screen controller, main CPU, and LCD controller. The contact screen and the contact screen controller are the whole ...

The touch screen interface is the same as the general interface, in addition to the touch screen interface, other user interfaces include web interface, software interface, game interface and mobile phone interface. Touchscreen interfaces have many similarities with them: Fundamentally, they are all interactive systems, and they are all ...

The interior of the touch screen can be roughly divided into: communication interface unit, driver unit, memory variable unit, and display unit. In addition to the display unit, the other 3 units are invisible to us inside the touch screen. 1. Communication interface ...

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. ...

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.

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 ...

Hitec touch screen selection: 10.4" Series: PWS6A00T-N (True Color Network), PWS6A00T-P (True Color Enhanced), PWS6A00T-S (Color Basic) 7.5" Series: PWS6800C-N ...

1. Projective capacitive contacts Although the basic structure and working principle of a projected capacitive contact screen is the same as that of a four-wire impedance film, the projected capacitive impedance film does not go through the contact field, but captures the change in capacitance between the electrodes. Generally speaking, when using the form of a capacitive sensor, it can be ...

Industrial tablet PCs are a branch of computers, which is different from commercial computers mainly because the tablet PC specification can continue to maintain stable performance parameters in different natural environments. Industrial tablet PCs are mainly used in telecommunications, electric power, multimedia systems, national defense and security.

Resistance contact is divided into four-wire resistance and five-wire resistance contact, the simple difference is four wires and five wires in the functional area. A constant voltage of 5V is added to each layer of the two-layer transparent metal layer with four-wire resistance analogue technology: ...

The contact screen of mobile phone capacitive contact screen and resistance contact screen are mainly different in contact sensitivity, accuracy, cost, multi-point contact feasibility, damage resistance, cleaning, and sunlight visibility. Contact sensitivity, 1 ...

(1) After the terminal is turned on, find out whether each calibration teaching file is not clicked in the execution step (2) If it exists, perform the step (4); (2) After the boot is finished, the active high-motion is the quasi-program, prompting the user to calibrate the touch screen, after the calibration is completed, the touch screen driver ...

Due to the large number of noise sources, the contact screen controller needs to be adapted to the different noise sizes and types that exist in the system for a given time. To ensure the highest robustness in noise immunity, the first factor to focus on is the signal-to-noise ratio (SNR). There are a few different features that we can progress through...

As a display terminal, the industrial display and the general computer display seem to be very similar in appearance, but in fact, there are great differences between the two in terms of structural planning, material selection and functional characteristics. Today, Freer has been planning the structure of the whole machine, the resolution and the appearance of the role, and the information ...

Human Machine Interaction (HMI), also known as user interface or user interface, is a preface and dialogue interface for transmitting and communicating information between humans and computers, and is an important part of the computer system. It is the interaction and information gap between the system and the user.

How to repair the Hitec touch screen when common problems occur 　　If the Hitec touchscreen display is confused, there are many reasons. For example, if the battery voltage is too low, the display will be confused. In addition, it may be that the power strip in the mechanical equipment is not installed and the storage area is chaotic ...

When the man-machine is started, the man-machine will check whether the hardware project is normal, and the results of its viewing will be displayed in the display area of the LCD. If there is an abnormal item, it will be marked "Failed" on the right side of the project, and the ...
