Als een van de moderne high-tech apparatuur en machines, vervangt de all-in-one touch-machine langzaam de positie van het eenvoudige touchscreen, zodat gebruikers echt de kenmerk dat mens en machine vrij kunnen communiceren.
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:
Het capacitieve touchscreen van de capacitive touch all-in-one machine gebruikt de huidige inductie van het menselijk lichaam om te werken. Het capacitieve touchscreen is een vier-laags composiet glazen scherm. Het binnenoppervlak en de tussenlaag van het glazen scherm zijn elk gecoat met een laag indiumoxide (ITO). Dunne beschermlaag van siliciumglas. De sandwich ITO-coating wordt gebruikt als werkoppervlak, vier elektroden worden op de vier hoeken getekend en de binnenste ITO wordt gebruikt als de afschermingslaag om een goede werkomgeving te garanderen.
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
De belangrijkste componenten die door de touch all-in-one zijn geïntegreerd, zijn: frontframe van geborsteld aluminium, touchframe, gehard glas, beeldscherm, metalen achterkant, muurbevestiging, ops industriële computer (of gewone computer ) weergavebord, voedingskaart, uitbreidingskaart, decoderkaart, netsnoer, voedingsadapter.
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.
