| 摘 要： | 介绍了医用电子内窥镜的结构原理以及驱动系统的设计与实现，并主要论述了驱动的方案及其功能，及以FPGA（现场可编程门阵列）为核心的驱动速度及运动方向控制。该微型驱动系统经实验验证。其直线移动速度可在0-10mm／sg围内调节，可平稳灵活地前进、后退及转弯。可编程逻辑器件在步进电机控制中将发挥其可靠性、灵活性等独特的作用。

| Abstract: | Medical endoscope capsule is described from its construction principle and drive system. The scheme and function of the drive system, especially the driving velocity and the direction control for that based on FPGA, are introduced in detail. Experiments indicate that the micro-drive system, with a linear speed ranging from 0 to 10 mm/s, can move forward and backward, and turn left and right discretionarily. The availability of programmable logic device makes the system reliable and flexible. |
