摘 要:本次设计采用的核心控制单元是单片机AT89C51,用红外光电传感器实现对外部信号的检测,然后由四位LED数码管来显示其计数的数值,在此设计的基础上添加了报警功能模块,从而使此次设计更加智能。用这种思路设计的新型智能产品自动计数器优点是容易编程,且电路结构简单、实时性好、操作步骤简单。34252 毕业论文关键词:单片机AT89C51;红外传感器;蜂鸣器;LED数码管
The Design of The Automatic Counter New Intelligent Product
Abstract:The design of the core control unit uses a single-chip AT89C51, infrared photoelectric sensor to achieve access to external signals, and then by the four LED digital tube to display the value of its count, on the basis of this design adds alarm function modules to make the design more intelligent. New intelligent product advantages automatic counter with this line of thinking design is easy to program, and a simple circuit structure, real-time, simple operation steps.
