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 various industries such as telecommunications, electric power, multimedia systems, national defense security, automated machinery, processing and manufacturing industries, and most of them are used for human-computer interfaces, thin clients, PLC and POS and other communication and control terminals, which are better solutions for human-computer interface and production process control.
In terms of production structure, the industrial tablet computer is composed of three parts: industrial control server, display and contact screen. In this side, the industrial control server (industrial computer) is equivalent to the desktop computer server in our business. This small part is a key part of embodying a company's intelligent production. The industrial computer specification is relatively strict, and the specification is extremely high in terms of temperature resistance, anti-sensation, dustproof, and waterproof level. These fundamental features are to ensure the stability of the tablet's operation.
Industrial tablet resistive screen, pressure magnetic induction, demand for force will have a response, only the demand strength is more suitable, resistance screens are quite flexible. The advantage of resistive screens is that they can be accurately positioned, which is more suitable for various industrial production sites. The disadvantage is that it does not support multi-point contact, and the sensitivity is not as high as that of a capacitive screen.
In fact, the use of industrial tablet PCs is very ubiquitous, and the tablet computers we see on the spot in some industrial production can be embedded in machinery and equipment, cabinets or placed on the actual operating table, and do man-machine display operation panels, in banks, shopping malls, hotels, railway stations, buses, subway stations, parks and other public places to do media (advertising) players or query terminals, etc., in telecommunications, electricity, multimedia systems, national defense security, automated machinery, processing and manufacturing industries, etc.
