6、序控制器（ProgrammableLogicController）简称PLC,是一种以微处理器为核心的用于工程自动控制的工业控制机，其本质是一台工业控制专用计算机。它的软、硬件配置与计算机极为类似，只不过它比一般计算机具有更强的与工业过程相连接的接口和更直接的适应于控制要求的编程语言。硬件主要由中央处理单元CPU、存贮器、输入/输出单元以及编程器、电源和智能输入/输出单元等构成.PLC是一种专为在工业环境应用而设计的数字运算电子系统，它是以微处理机为基础，综合了计算机技术、自动控制技术和通信技术等现代科技而发展起来的一种新型工业自动控制装置，是当今工业发达国家自动控制的标准设备之一。自动售

7、货机是集声、光、机、电于一体的智能科技产物,进入21世纪，自动售货机也将进一步向节省资源和能源以及高功能化的方向发展。使未来的自动售货机不仅仅具有售货功能，而是更加多元化,及人性化;如：手机支付、远程联机管理、个性的LCD广告显示屏、更节能。自动售货机的普及在某种程度上能反映一个国家的科技发展水平，是一个国家文明程度的象征。实践和直觉告诉我们，自动售货机在中国的横空出世，必将为国内的食品、香烟、饮料等诸多行业的发展带来新
