plc机械手控制系统文献综述(包括外文翻译)-机械手(编辑修改稿)内容摘要：

(3)数据采集、分析处理。 如控制中的数据采集、算术运算、函数运算、逻辑运算、数据传输、转换、捧序和查表等操作。 综上用 PLC 作为控制系统控制 机械手 写字 的设计是一种方便、实用、可靠的控制系统设计方案。 通过收集各种资料和初期的规划我已对将要进行的设计非常了解，相信在老师的指导和我自己的努力下我可以很好的完成设计任务，虽然期间肯定会遇到这样或那样的困难，但是我有信心做好这一切。 外文原文及其翻译： The advantages of PLC control Any control system goes through four stages from conception to a working plant. A PLC system brings advantages at each stage. The first stage is design。 the required plant is studied and the control strategies decided. With conventional systems design must be plete before construction can start. With a PLC system all that is needed is a possibly vague idea of the size of the machine and the I/O requirements (how many inputs and outputs). The input and output cards are cheap at this stage, so a healthy spare capacity can be built in to allow for the inevitable omissions and future developments. Next es construction. With conventional schemes, every job is a ‘oneoff’ with inevitable delays and costs. A PLC system is simply bolted together fro m standard parts. During this time the writing of the PLC program is started (or at least the detailed program specification is written). The next stage is installation, a tedious and expensive b。
