As we all know, industrial tablet PCs are used in industrial environments. Some environments are poor condition. So how to ensure the service life of industrial tablets? Some customers also will consult the problems of service life of industrial tablet PC, here we will get understanding for it.
First of all, let's talk about the structure of industrial tablet computers. On the terms of hardware, it is not much different from the ordinary commercial computers. It is composed of the main board, CPU, hard disk, memory, graphics card, display screen, etc. However, in the aspects of application, the industrial tablet computers usually used in relatively harsh industrial environments, requiring more stringent hardware than ordinary hardware. Especially for the motherboard, it should be industrial-graded, fanless cooling heat-dissipation system and durable aluminium alloy materials for the shell.
For industrial tablet PC touch screen types, generally two main touch types are popular in market: capacitive touch screen and resistive touch screen. These two touch screens, like printing consumables, will disappear after a long time of using. In the process of using touch screen, resistance touch realizes the operation and control of screen content through the principle of pressure induction. Resistance touch screen cooperates with multi-layer composite film. The conductive layer and glass layer inductor on the surface of multi-grease are separated by many tiny separating layers. The current passes through the surface and touches the surface pressure lightly. The controller reads the corresponding current from four corners and calculates the distance of finger position. It can form accurate touch positioning.
The working theory of capacitive touch screen is to paste a transparent special metal conductive material on the glass surface. When the finger touches the metal layer, the capacitance of the contact point will change, which will change the frequency of the oscillator connected with it. The touch position can be determined by measuring the frequency change. Due to the capacitance varies with temperature, humidity or grounding conditions, its stability is poorer than resistive touch and it will drift in some situation.
The service life of industrial tablet PC is determined by many factors. In order to ensure longer service life, except standardized operation, regular cleaning and maintenance of equipment is necessary, also including the maintenance for spare parts.
