微型自动化立体仓库设计

摘要

The miniature three-dimensional storehouse is the experimental equipment for colleges' machinery and automation, which has nine racks, we can realize control logic of the device. According to the material weight and initial conditions of acceleration, through computing component of forces in X, Y, Z three directions and convert torque, we can compute selection of DC motor and bearings, design of screw-nut pairs, guide ways and airframe. According to the action logic of DC motors and hardware configuration, we can complete design of I/O interface circuit. Using MSComm and FX2N-PLC communication protocol , we can write VB code, which realizes serial communication between PC and PLC, completes the control of displaying, seeking goods, getting goods, delivering goods, stopping, setting to zero.%微型立体仓库是面向高校机械及自动化专业的经济型实验装置,其机械系统可实现对9个货位物料的存取,控制系统实现对装置的逻辑控制.根据物料重量及加减速初始条件,计算X、Y、Z三个方向分力及折算转矩,选择直流电动机和轴承,设计丝杠螺母副、导轨和机体,完成机械系统的设计；根据3台直流电动机的动作逻辑和硬件I/O配置,完成接口电路系统的设计.上位机使用VB的MSComm控件,编写FX2N-PLC通信协议代码,实现上下位机的串行通信,完成显示货位号、寻货、取货、存货、急停、回零等动作的控制.
