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.

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.

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 ...

Capacitive technology contact screens are operated using the current induction of the human body. 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 maintenance layer, and the interlayer ITO coating is used as the working surface, and the four corners are led out ...

Touch screen is a new part in today's new product planning, in the past few years there are many touch screen factories born, users may not be able to judge the quality of a touch screen produced by a certain company from the appearance, we propose some simple methods to be able to see the quality of the product from the appearance.

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 ...

The communication method is selected to control the inverter to complete the system control function, and the user can control the operation of the system through the touch screen. Through the pressure transmitter installed on the outlet pipe network, the outlet pressure signal is turned into a 4-20mA or 0-10V standard signal and sent to the built-in PID adjustment of the PLC.

Imprecise screen orientation: can be positioned from scratch by the driver software. Contact orientation and screen cursor inversion: When the device touches the screen, the orientation of the screen is inverted, please adjust the contact screen orientation according to the guidelines of the right-hand orientation. ...

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 ...

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...

The control of the PLC itself is completed by the change of the control register D, the input port X, the soft relay condition M and the time relay T and other condition variables, so as long as the condition of these variables can be corrected, the control of the PLC can be completed, and the touch screen can pass through the 232 or ...

As an input device, the touch screen has the advantages of easy to use, ruggedness, fast response time, and space saving, and the user can use it directly through the contact screen to complete the operation, without the need for a keyboard or mouse, and is very practical and widely used. ...

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 ...

TWO HITECH TOUCH SCREEN COPY PROGRAM METHODS: 1. Make a communication cable first. HMI1 COM port HMI2 COM port 25-pin female 25-pin female RXD 3 -------------------------------- TXD 2 ...

Human-computer interface (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 preface to the interaction and information communication between the system and the user, and it realizes the internal aspects of the information.

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. ...

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 ...

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, ...

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 ...

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