摘要: 本论文设计的重点在于, 在实际控制工程当中, 利用 80C51 单片机和 A/D 转换器实现对被测量的数据处理,同时通过 D/A 转换器把相应的控制量输出给被控对象。在实现以上基本功能的基础上,还进行了一系列的功能扩展,如报警功能、键盘控制功能和 LED 显示功能。关键词: A/D 转换器, D/A 转换器, 80C51 单片机,报警电路,键盘, LED 显示 Abstract : In this paper, the design focuses on the actual control engineering, using 80C51 MCU and A/D converter based on measured data processing, and through D/ A converter to the corresponding control output to the controlled object. In the realization of the basic functions on the basis of the above, also undertook a series of extensions, such as alarm function, keyboard control and LED display function.
