母线槽是一种新型配电导线，它的两个主要技术参数是指绝缘强度和导线的电 阻。论文根据自动检测母线槽导电片电阻和导电片之间绝缘强度的要求，主要 介绍了母线槽参数检测机构中气压传动控制系统的设计方法、过程参数和结果 等，另外还介绍了步进电机驱动电路的设计。
本传动机构共有六个动作需要由气压传动装置控制，需要八只气缸。其中，两 只气缸控制母线槽两端测量头的伸缩；两只气缸控制测量头横向定位；两只气缸控 制母线槽长度方向定位；两只气缸控制母线槽的升降（然后对其进行包装）。论文涉 及到各个气压传动回路图的设计，各个气缸及辅助元件的相关尺寸的计算，接着是 控制回路中的各种气压元件的选择。另外还计算出了普通型单活塞双作用气缸的各 个参数值，并设计出了它的结构图。
设计五相十拍步进电动机驱动电路时选择了 89C2051作为环形分配器，而功率 器件选用电压型的VMOS管。该电路设计成恒流斩波电路，论文中大概介绍了步进电 机的相关知识和基本工作原理，并详细介绍了斩波恒流细分驱动方案的原理。此外, 本次设计还分别对相序分配的硬件接线和软件程序部分做了设计和说明。

ABSTRACT
The Bus duct is a new kind of lead for electric conductivity,The two of main techniques of the Bus duct are Insulation Strength and Resistance of wires. According to the requirements of automatically detecting the resistance of conducting plates and the insulation strength between them, The design of Pneumatic Transmission system and Stepping Motor Drive Control Circuits for the Bus duct Parameter Detection machine are introduced in this thesis. In addition, the design of Step Motor Drive Control Circuits is introduced.
The Pneumatic Transmission setup has six actions which need to be controlled by Pneumatic Transmission. Eight Cylinders are needed. Two of them are used for controlling the flex of the detection. Two are used for controlling transverse orientation of the detection .Two are used for controlling orientation in length of the Bus duct. Another two are used for controlling the up and down of the Bus duct (preparing for packing it)・ Then the thesis comes down to designing drawings of the loops in Pneumatic Transmission system ,and the size of Cylinders and device relationally are calculated in this thesis, with that dev
