1. 人机界面产品的定义

连接可编程序控制器（PLC）、变频器、直流调速器、仪表等工业控制设备，利用显示屏显示，通过输入单元（如触摸屏、键盘、鼠标等）写入工作参数或输入操作命令，实现人与机器信息交互的数字设备，由硬件和软件两部分组成。HMI为英文Human-Machine Interface的缩写。

2. 人机界面（HMI）产品的组成及工作原理

人机界面产品由硬件和软件两部分组成，硬件部分包括处理器、显示单元、输入单元、通讯接口、数据存贮单元等，其中处理器的性能决定了HMI产品的性能高低，是HMI的核心单元。根据HMI的产品等级不同，处理器可分别选用8位、16位、32位的处理器。HMI软件一般分为两部分，即运行于HMI硬件中的系统软件和运行于PC机Windows操作系统下的画面组态软件（如JB－HMI画面组态软件）。使用者都先使用HMI的画面组态软件制作“工程文件”，再通过PC机和HMI 产品的串行通讯口，把编制好的“工程文件”下载到HMI的处理器中运行。
