摘要
以CPLD(复杂可编程逻辑器件)为核心的时间控制器与传统时间控制器相比,具有外围电路少、集成度高、可靠性强等优点。该时间控制器的设计是以VHDL为开发工具,以MAX+PLUSⅡ为软件平台,采用模块化设计。该控制器具有数字时钟功能,又有定时器功能,能方便灵活地设置开启时间和关闭时间,在路灯、广告灯箱、霓虹灯等处具有广泛的应用。文中给出了部分模块的VHDL源程序及仿真图。
The time controller whose core is CPLD with virtue of few periphery electric circuit, high intergration and high reliability is different from the traditional ones. It is modular designed with VHDL language and MAX ＋ PLUS Ⅱ software. It provides the function of digital clock as well as the timer, which is convenient for setting of the time. The time controller can be applied universally to the street lamp, flash advertisement light boxes and neon lamp, etc.. The VHDL source program and the simulation chart of the partial modules are given.
