摘　　要：根据自动化立体仓库运行的基本原理和结构,在整个控制系统中以三菱FX2N系列PLC作为核心控制元件,专用键盘作为人机接口部件,控制步进电机来驱动一个有三自由度的仓库模型在高强度导轨上做三维运动。以步进电机每转输出的脉冲数为基础,通过键盘对每个仓位予以地址编码,通过PLC对命令键盘进行扫描并得到相应的仓位号,当PLC接收到来自键盘的输入命令后,便输出对应仓位的脉冲数,经过驱动器驱动步进电机按设定的方向转动一定的角度,进而控制传动部件丝杠旋转进行准确的定位,以完成货物的存取功能。According to the automation stereoscopic warehouse operation principle and structure, the whole control system with the Mitsubishi FX2N series PLC as a core control element, a special keyboard as the man-machine interface unit, control step motor to drive a three-degree of freedom of the warehouse model in high strength rail to do the three-dimensional motion. The stepping motor rotates the output pulse number as the basis, through the keyboard to each position to address code, through the PLC on the orders of the keyboard scan and corresponding positions, when PLC receives input from keyboard commands, then output corresponding to the position of the number of pulses, the driver to drive the stepper motor in accordance with set direction rotates a certain angle, thereby control the transmission parts screw rotation for accurate positioning, in order to complete the goods access function.
