设计简介
摘要
在钢管生产过程中，需要实时了解每根顶杆的长度、外径、使用次数等信息。本论文介绍了通过在顶杆尾部开槽的方式，实现顶杆的识别与信息跟踪，基于 PLC的控制系统，给出了系统的检测原理，系统构成及软件程序。本课题主要研究工作：
第一章综合叙述了钢管的工艺生产流程及API国际标准；说明了国内顶杆自动识别系统的开发现状及存在的问题并阐述了顶杆自动识别系统的工作原理及流程；陈述了课题的来源和论文的主要工作和意义。
第二章提出了系统总体的设计要求；根据钢管的具体参数和工作要求对检测系统的整个机架部分进行设计。
第三章主要是对组成机架所需要的主要机械零部件（气缸和滚珠丝杠副）进行选型，并对选择过程做出相应说明，以及这些零部件相关的力学和强度校核计算。
第四章简述了PLC编程的方式和S7 400的组成；提出了PLC程序的测试策略；介绍了传感器的选型，信号转换和安装。
第五章总结了顶杆自动识别系统和软件系统开发过程所做的工作，并对系统的改进方向进行了展望。

Abstract
In the expansion of production, it is necessary to understand the real-time each mandril length, diameter, frequency of use and other information. Introduced through the mandril slotting the tail, and push to achieve the identification and tracking information; PLC-based control system, the system is the detection principle, the system and software program. The main research topics:
The first chapter synthesis narrated the steel pipe craft production process and the API international standard; Explained the domestic roof bar automatic diagnosis system development present situation and the existence question and elaborated the roof bar automatic diagnosis system principle of work and the flow; Stated the topic origin and the paper prime task and the significance.
The second chapter set the system overall design request; To examine the system according to the steel pipe concrete parameter and the work requirement the entire rack section to carry on the design.
Third chapter mainly is to composes the main mechanical spare part which the rack needs (air cylinder and ball bearing guide screw vice) carries on the shaping, and to chooses the process to make the corresponding explanation, as well as these spare part correlation mechanics and intensity examination computation.
The fourth chapter to summarize the PLC programming way and the S7 400 compositions; Proposed the PLC procedure test strategy; Introduced the sensor shaping and the signal transformation. Fifth chapter summarized the work which the roof bar automatic diagnosis system and the software system performance history does, and has carried on the forecast to the system improvement direction.
