Smart discuss: HMI man-machine interface include

a lot of people do not understand human machine interface or HMI human-machine interface, think he is a kind of high-tech product, actually the man-machine interface in our life, everywhere, for everyone who participate in man-machine communication areas there is the man-machine interface. Knowledge of human-computer interface, let's listen to smart technology solutions.

what HMI man-machine interface including

the man-machine interface consists of two parts, hardware and software products, hardware part includes a processor and a display unit, input unit, communication interface, data storage unit, etc. , including the performance of the processor determines the performance of the HMI product, is the core unit of HMI.

according to different HMI product level, the processor can choose different 8-bit, 16-bit and 32-bit processor. HMI software is generally divided into two parts, namely to run on software and hardware of the HMI system running on PC screen configuration software under Windows operating system. The user must first use the HMI touch screen screen configuration software production & other Engineering documents & throughout; , and then through the PC and HMI product serial communication port, the establishment good & other; Engineering documents & throughout; Download the processor in the running of HMI.
