工业人机界面是一种带微处理器的智能终端，一般用于工业场合，实现人和机器之间的信息交互，包括文字或图形显示以及输入等功能。目前也有大量的工业人机界面因其成熟的人机界面技术和高可靠性而被广泛用于智能楼宇、智能家居、城市信息管理、医院信息管理等非工业领域，因此，工业人机界面正在向应用范围更广的高可靠性智能化信息终端发展。

Human machine interface is a smart terminal with microprocessor. It is commonly used in industrial occasions to achieve information interaction between people and machines, including text or graphics display and input functions. At present, there are a large number of industrial man-machine interface because of its mature man-machine interface technology and high reliability and is widely used in intelligent buildings, smart city Home Furnishing, information management, hospital information management and other non industrial areas, therefore, the industrial man-machine interface is applied to a wider range of high reliability intelligent information terminal development.

根据功能的不同，工业人机界面习惯上被分为文本显示器、触摸屏人机界面和平板电脑三大类。文本显示器一般采用单片机控制，图形化显示功能较弱，成本较低，适合低端的工业人机界面应用。触摸屏人机界面采用较高等级的嵌入式电脑设计，目前比较流行的设计是采用32位的ARM微处理器，主频一般在100MHz以上，采用Linux或WinCE等嵌入式操作系统。触摸屏人机界面具备丰富的图形功能，能够实现各种需求的图形显示、数据存储、联网通讯等功能，且可靠性高，成本比平板电脑低，体积小，是工业场合的首选，近期也逐渐替代工业PC成为主流的智能化信息终端。平板电脑是扁平设计的工业PC机，一般采用X86架构的设计，Windows XP操作系统，带触摸屏，CPU功能强大，可以完成大量的数据运算以及存储，缺点是成本较高，且部分带硬盘和风扇的设计降低系统可靠性。

According to the different functions, the industrial human-machine interface is used to be divided into three categories: the text display, the touch screen man-machine interface and the tablet computer. The text display is usually controlled by single chip microcomputer. The graphical display function is weak and the cost is low. It is suitable for the low end industrial man-machine interface. The touchscreen man-machine interface is designed with higher level embedded computers. The most popular design now is the 32 bit ARM microprocessor, whose main frequency is above 100MHz and adopts Linux or WinCE embedded operation system. Touch screen man-machine interface with rich graphics function, can realize the various needs of the graphic display, data storage, network communication and other functions, and high reliability, and low cost than the tablet computer, small volume, is the preferred industrial occasions, recently also gradually replace the industrial PC into intelligent information terminal main stream. The tablet computer is industrial PC flat design, the general design of X86 architecture, Windows XP operating system, with touch screen, CPU powerful, can achieve a large amount of data storage and operation, and the disadvantage is high cost, with the hard disk and the fan part decrease the reliability of the system.
