Human Machine Interface (HMI) is usually a medium for visual information interaction between automation systems and users. In industrial automation systems, HMI is usually connected with industrial controllers such as programmable controllers, general-purpose inverters, intelligent devices and equipment to achieve visual information interaction and operation between human and machines. Customarily, people often refer to HMI products with touch input function as panels, touch screens or industrial tablet PCs.
The structure principle and function of HMI products HMI products consist of two parts: hardware and software. The hardware part includes microprocessor, memory, input and display units, communication interface, etc. Among them, the microprocessor is the core of HMI and its performance determines the performance level of HMI products.
Underlined, our industrial touch panel computer is also used for automation system human-machine interface, of course, we belong to the high performance which is the same as the normal computer, high processor performance, running storage large. Like our industrial touch panel computer high-performance, the price can be much higher than the ordinary, a few thousand, the ordinary hundreds on it. Why the price difference is so big, or the performance of the previously mentioned problem of high and low, ordinary processor single-core, less than 1GHz, running and storage only a few megabytes, the display resolution are not high, touch experience is not high, like this low-end is generally used to control the physical buttons.
The basic functions of HMI products include real-time and historical data trend display of equipment working status (such as text, graphs, curves, etc.); data and text input operation, report and alarm generation and recording, printout; production recipe storage, automatic recording of equipment production data; logic and numerical operations; and the ability to connect to industrial control networks, enabling operators to control machines and devices directly through graphical interfaces. High-performance HMI control system industrial panel PC can run larger and more complex systems.
