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,
