摘要
针对原高架立体仓库结构复杂、设备老化,且难以维护的缺点,在最大程度地保留原设备的同时对其提出改造方案。首先列举了结构改造方案;然后通过对堆垛机功能分析,并借鉴软件工程的思想,用模块化方法进行程序设计,极大地提高开发效率;最后对模块化设计的缺陷进行了分析,并给出解决方案。另外还对基于DRIVECOM接口的变频器给出速度控制方案。经运行,为系统设计的wincc界面友好、简介操作简单,PLC程序运行可靠。
For overcoming the shortcomings including redundant structure,outdated equipment and lacking maintenance of the high-rack storage,a reform project is proposed trying to utilize the old equipments.First,a new updated structure is shown in this paper.Second,based on the analysis of the stacker＇s function and with the help of the conception of software engineering,a modular approach is used to design this program so that the productivity can be greatly increased.Thirdly,this paper analyzes the modulization＇s disadvantage and the remedies are followed.In addition,a velocity-control scheme is proposed based on the frequency converter with DRIVECOM interface.After practical running,the HMI with wincc is friendly and PLC program is reliable.
