As one of the modern high-tech equipment and machines, the all-in-one touch machine is slowly replacing the position of the simple touch screen, so that users can truly feel the feature that humans and machines can interact freely.
Recommended touch all-in-one: horizontal touch all-in-one, wall-mounted touch all-in-one
The most commonly used types of touch all-in-ones are capacitive touch all-in-one and infrared touch all-in-one;
The working principle of capacitive touch all-in-one machine:
The capacitive touch screen of the capacitive touch all-in-one machine uses the current induction of the human body to work. The capacitive touch screen is a four-layer composite glass screen. The inner surface and the interlayer of the glass screen are each coated with a layer of indium oxide (ITO). Thin silicon glass protective layer. The sandwich ITO coating is used as the working surface, four electrodes are drawn on the four corners, and the inner ITO is used as the shielding layer to ensure a good working environment.
When a finger touches the metal layer, the electric field of the human body and the surface of the user and the touch screen form a composite capacitance. Therefore, for high-frequency current, the capacitance is a direct conductor, and the finger draws a tiny current from the contact point. This current flows from the electrodes at the four corners of the touch screen. The current flowing through the four electrodes is proportional to the distance from the finger to the four corners, and the controller obtains the position of the touch point by accurately calculating the ratio of these four currents.
The working principle of infrared touch screen all-in-one machine
The infrared touch screen of the infrared touch all-in-one machine uses the dense infrared matrix in the x and y directions to detect the user's touch. The infrared touch screen is equipped with a circuit board frame in front of the display, and the circuit board is equipped with infrared emitting tubes and infrared receiving tubes on the four sides of the screen. , One to one corresponds to a crossed infrared matrix. When the user touches the screen, the finger will block the infrared rays passing through the position, so the position of the touch point on the screen can be judged.
The structure of the touch one machine
The main components integrated by the touch all-in-one include: brushed aluminum front frame, touch frame, tempered glass, display screen, metal back shell, wall mount, ops industrial computer (or ordinary computer) display board, power supply board, expansion board, decoder board, Power cord, power adapter.
Touch all-in-one computer: There are two kinds of all-in-one touch computers, one is a common type of computer, and the other is an industrial ops computer. The performance of industrial ops is relatively excellent.
Tempered glass: Tempered glass is the same as the screen of a mobile phone. Tempered glass plays a role in protecting the touch screen.
Metal back shell: The metal back shell is necessary to prevent the deformation of the touch all-in-one. If a plastic back shell is used, the entire body is relatively easy to deform.
The all-in-one touch machine produced by Rongda Caijing has always adhered to the three-in-one business philosophy of "hardware production, software research and development, and after-sales service" to provide a full range of solutions. Help enterprises to achieve informatization, intelligence, and humanity Chemical production management helps the development of smart factories and digital factories.
