Human-machine interface technology - Hitec touch screen

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 ...

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. ...

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: ...

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 ...

Step 1: Admit to powering on the touch screen and enter the touch screen welcome interface Step 2: Press "Enter System" with one finger at the top of the welcome screen to enter the "System Main Screen" Step 3: Parameter setting. ...

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.

Taiwan Hitec launched the new touch screen PWX8700T-N and PWX8A00T-N touch screens, which have the following features and applications: The smartest design planning software ★Office-style editing interface ★ Rich 3D style pre...

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 a lot of similarities with them: basically, they are all interactive systems, and they are all ...

Tablet PC, also known as industrial contact tablet, is an inductive LCD display device that can transmit keying signals such as auxiliary contacts, when touching the graphic buttons on the display screen, the haptic feedback system on the display screen can drive various connected devices according to the pre-programmed program, which can ...

After clicking on the three corners of the contact screen, enter the offline form (note: different contact screens enter the offline form in different ways). Once in the offline format, click "INITIALIZE", and after clicking, keep clicking "SET-UP-I/O" and then "SET-UP-TOUCH-PANEL". ...

The two-layer transparent metal layer of the four-wire resistance analogue technology operates with a constant voltage of 5V on each layer: one vertically and one horizontally. A total of four cables are required. High-resolution, high-speed transmission response. Surface hardness treatment to reduce abrasions, scratches and chemical resistance. With light ...

Many people have encountered industrial contact screen contact no response, no matter how we point to the industrial contact screen is not responding, at this time many people don't know what to do, today let's take a look at what to do when encountering industrial contact screen contact no response. ...

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, ...

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. 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...

1. The touch screen part is a glass product, the glass corners are relatively sharp, and the assembly needs to be carried out with gloves/finger covers. 2. The touch screen part is a fragile glass product, and do not exert a strong impact on the touch screen during assembly. 3. Pick and place products ...

1. In the daily use of the equipment, try to prevent frequent power off and off, and sudden power failure during operation will cause certain damage to electronic components and hard disk errors; In terms of power supply, keep operating in a stable voltage environment, too low voltage, too high voltage will affect the function of the equipment, and will also ...

To improve the anti-disturbance ability of the PLC system, we can select products with higher anti-disturbance ability when carrying out the anti-disturbance planning of detailed engineering, and adopt methods such as pressing the disturbance source, blocking or attenuating the propagation path of electromagnetic disturbance, and using software means to improve the anti-disturbance of the equipment and system.

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...

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.
