这是一个工业生产节能时控器的单片机程序（C语言）。工业生产节能时控器由单片机、按键输入、数码管、继电器、蜂鸣器、电源等组成。单片机是整个系统的核心，整个系统的所有运行均由单片机完成，如产生精确的时钟及计时、数码管输出扫描显示、输出去动继电器、驱动蜂鸣器、扫描按键输入等。单片机型号为AT89C2051。-This is an industrial production of energy-saving controller of the microcontroller when the program (C language). When energy-saving controller of industrial production by the microcontroller, key input, digital control, relay, buzzer, power supply and other components. SCM is the core of the whole system, all run by the system microcontroller to complete, such as generating precise clock and timing, the digital output scan display, output to the relay, buzzer driver, scan key input and so on. MCU models for the AT89C2051.
