摘要
智能高速球作为监控系统的前端,是一种很有发展前途的产品。这在西方发达国家广泛应用高速球的情况上就可以得到很好的证明,可以肯定在不久的将来国内市场对高速球会有很大的需求。高速球作为一种新生事物,它的出现,才是“监控”的功能得以全面的拓展。因此,本论文认为有必要对高速球控制系统的结构与原理进行了解,掌握,在理解的基础上改善高速球的性能,以致达到更好的监控效果。
论文主要介绍以51单片机来实现高速球的监空功能。具体思路是以51单片机来控制步进电机,以步进电机来带动高速球内置摄相头的转动,包括水平方向的左转,右转和垂直方向上转,下转。论文涉及了相应的硬件设计和软件程序编写。
关键词: 高速球,51单片机,步进电机
Abstract
High speed dome,which is the front part of a monitor system,is a hopeful product.This idea can be well proved by the truth that this kind of domes are widely applied in the west developed countries,and it is strongly believed that domestic market will require these products in a large account before long.The high speed dome is a new object in our country now,whose appearance brings the possibility to well develop the function of the monitor system.So,it’s necessary to learn and master the structure and theory of the dome,and finally we can add new functions to the domes to fulfill better the needs of customs.
This essay mainly discuss a way to realize the dome’s function based on MCU-51,and put up simple introductions of the hardware designment and the program code involved.It’s concret thought is to use MCU-51 to control the movement of the step-take electric machineries,and then the step-take electric machineries promote the camera to move,which should complete actions of rolling around about 360 degrees in the level direction and of overturning about 180 degrees in the vertical one.
Key words: high speed dome, MCU-51, step-take electric machinery,
