TFT-LCD視覺檢測之伺服定位系統研製

Abstract

本論文主要目的是以Visual C++作為軟體開發工具，利用市面上所販售的運動控制卡，設計一套以廠商的TFTD機台(三軸微步進馬達平台)為受控端的運動控制系統。

使用者在PC端透過視窗化的控制介面，將下達的運動指令傳送至PCI-8134運動控制卡，運動控制卡再將運動指令轉成脈波形式輸送至馬達驅動器，而驅動器在將脈波訊號轉成電壓或電流形式控制三軸的步進馬達。控制介面分成四部份 : 第一部分的功能是控制速度和位移量；第二部份的功能是監控平台目前的狀態；第三部份的功能是將面板切割成九宮格，根據使用者所點選的區域做移動控制；第四部份的功能則是在該區域以弓字形的方式作移動控制。

此運動控制系統。提供異於操作的視覺化控制介面，能及時精準的控制運動平台，並隨時監控平台的所在位置與回授狀態，對平台運動 極限的發生，做出適當的保護措施，避免使用者不當的操作，而導致機台毀損甚至發生意外，更能針對業界的需求，規劃運動控制的路徑。

This main purpose of thesis is using Visual C ++ as the software developing tool , utilizing the motion control board sold on the market, to design a set of axis controlled motion control system for a manufacturer's TFTD machine(three axes micro-stepper motor platform )

Users can send motion instruction through the windowing control interface at a PC terminal to the PCI-8134 motion control card which translates the motion instruction into pulse signal and then sends it to motor driver.Furthermore, the motor driver transfers the pulse into voltage or current type to control a three axes micro-stepper motor. The control interface can be divided into four parts: the first part is used to control the speed,and displacement；the second is used to monitor the status of platform；the third is to provide a command the panel with nine sections,according to user-selected area to control the movement；the fourth is to move and control by way of bow font in this area.

This motion control system provides simple visual control interface, and it can accurately control the motion platform immediately.Moreover, it can not only monitor the location and feedback status of the platform at any time to take appropriate protection procedures when it comes up against the over-limited of motion platform, but also avoid improper operation by users which can causes damage to machines or even worse result in accidents.As well, this system can plan the route where motion control to the demand of the industry.
