Touchscreen interface design and operation

1. The difference between human-machine interface and configuration software Human-machine interface products, often referred to as "touch screen", include HMI hardware and corresponding special screen configuration software.

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. Resistive contact screen Analog resistive screen The analog resistive contact screen is what we generally call the "resistive screen", which is a kind of contact screen that uses pressure sensing to operate. It uses two layers of ITO (indium tin oxide) plastic film coated with conductive function, two pieces of IT...

1. Understand the function In order to make the human-machine interface play a better role at low temperature and achieve a good use effect, it is necessary to select a high-function machine, and the machine's ...

Human-computer interface, the real sense of human-computer interaction method is that people will get rid of any form of interactive interface, the method of entering information is becoming more and more simple, casual, capricious, with the help of artificial intelligence and big data, you can be very intuitive, direct, comprehensive capture of human needs, and...

Capacitive touch screen skills use human current to detect jobs. The capacitive touch screen is a 4-layer composite glass screen. The inner and outer surface of the glass screen and the interlayer are coated with a layer of ITO, and the outermost layer is a thin protective layer of silica glass. Sandwich ITO coating for the working surface, 4 edges guiding 4 electrodes, internal ITO for ...

1) Check whether the connection of the touch screen is right, and whether the connection of a cable connected to the keyboard port of the host (take the working voltage of the 5 volt touch screen from the keyboard port) is connected, please check the connection. 2) Observe the situation of the touch screen controlling the box light, if ...

The function of the touch screen is to control the soft relay of the plc, for example, if you use X3 as the start, then you can connect X3 in parallel in the PLC program, for example, M45, set a virtual button in the touch screen, and then set it to M45 action in its characteristics, then when the touch screen and PLC are connected, ...

Fault phenomenon Hitec contact screen, its click accuracy decreases, and the cursor is difficult to locate. Fault profiling processing 1) Run the Hitec Touch Screen Calibration Program. (Beginning--Settings--Control Panel--Sonic Screen---Cal...

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 computer systems. It is the interaction and information between the system and the user ...

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 ...

Problem phenomenon: A contact screen has no response after normal use for a period of time after being turned on. Problem profiling and processing 1. Check to see if the hard drive is turned off in the "Display Energy Saving Settings" of Wlndows9x. The way to do this is to right-click on the desktop and select the "Properties" ...

1. The human-machine interface is unresponsive, and there is no response to any part of the contact. Solution: In this case, first check whether the wiring interface is loose, and then check whether the serial port and the abort number are conflicted, if it is caused by conflict, then the resources should be adjusted to avoid ...

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...

SW1/SW2 is saved sw3/SW4 ON /ON/ normal operation form of the user ON/OFF/Executor produces burn-in program OFF/ON/Update BIOS OFF/OFF/Perform a hardware test SW5/Communication parameter setting ON/PWS/Hardware-based ...

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 ...

1. Human-computer interaction and human-computer interaction (English: Human–Computer Interaction or Human–MachineInteraction, referred to as HCI or HMI) is a study of the interaction relationship between the system and the user. ...

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 ...

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 ...

Shortcoming: 1. Ambient light factor, infrared acceptance tube has the scale of operation between small sensitivity and large illumination, but the contact screen product can not limit the scale of use, from the dark song hall private room to the outdoor use under the high-intensity sunlight on Hainan Island, as a product, it must adapt. ...
