毕业设计说明书 题 目:基于单片机的智能调节器设计 基于单片机的智能调节器设计 摘 要 关键词:;; The Design of Intelligent Regulator Based on MCU Abstract Intelligent instrument is a kind of intelligent measuring and controlling system that combines computer technology and measuring and controlling technology with MCU being its main body. Intelligent instrument has many strong-points which traditional instrument hasn’t, such as automatic operation, data processing and friendly man-machine conversation function. So, it can be applied widely in all kinds of fields. With the rapid development of microelectronics and information technology, intelligent instrument will develop in micromation, multifunctional and network direction. This design take the high-performance MCU 80C196KB as the core, and auxiliary by necessary periphery component, to complete the regulators functions. At the same time, this regulator also has the preliminary intellectualization. On the hardware circuit design, this paper describes various circuit modules in detail, and also gives the peripheral circuit design of the keyboard, the display, the communication and the print; In the part of software design, this paper shows the compiling and flow of software of MCU. Finally, in view of the problems and insufficiencies in this design, some recommendations and advices are presented.
