三维彩色扫描仪中的硬件接口设计

摘要：
 此次设计的课题是进行基于结构光测距技术的影视型三维彩色扫描仪中的硬件接口设计。影视型三维彩色扫描仪是获得被扫描物体立体的三维彩色立体模型的装置。硬件接口设计的主要目的是根据电脑主机的命令来控制转台转动和升降架的移动，包括方向控制，速度控制和转角控制。
 在^论文的开头，我们介绍了在Windows环境下，利用Visual C++6.0的Miscomm控件进行通讯的问题。并且给出了通讯程序。
 然后，文章介绍了串口通讯的原理和MAX232的通信协议以及具体的硬件实现电路。另外，针对通讯中可能出现的问题，文章提出了一些合理解决办法。
 最后，文章介绍了交流伺服电机的驱动模块，以及它与单片机接口的电路连接。松下MINAS系列伺服控制器的原理和特性也同时作了介绍。

The hardware interface circuit design
of 3D Color Scanner

Abstract:
 The subject is the hardware interface circuit design of 3D Color Scanner based on structure lighting. The Filmdom 3D Color Scanner is the instrument of rebuilding cubic and color pattern of scanned object.The main purpose of the design is to control the motion of rotator，including direction control,speed control and angel control.Basicly the hardware circuit is made up of two major section,i.e. communication interface circuit,rotator control circuit
  At the begining of the thesis ,it introduces the designing means by which a computer can communicate with a singlechip by MSComm of Visual C++ 6.0 in the circumstance of Window XP,And fully provides the program of communication .
  Then,the article introduce the principle of remote serial communication by RS232 series interface and the corresponding hardware configuration which can fullfill the communication function of the system. What's more,contraposing the problems possibly appeared in communication procedure,some rational resolvents are given to make the data trasmitted perfectly.
  At last,the artical introduce the servo driver and it's connection with singal chip misyoco.And the principles and properties of Panasonic MINAS seiries servo driver are also outlined.

 KEY WORDS: 3D Color Scanner ，Visual C++，Singal Chip Micyoco, RS232 series interface， AC servo motor, AC servo driver, signal timing , serial communication
