文章在MAX+PLUS II 开发环境下采用VHDL 语言,设计并实现了温控定时喷灌系统, 讨论了系统的三个组成模块的设计和VHDL 实现。整体的生成采用图形输入法。波形仿真及下载芯片测试表明该设计方案是可行的。该设计首次实现了温度控制下的定时喷灌系统。 关键词: 喷灌;硬件描述语言; 现场可编程门阵列 Abstract:This paper designs and implements a Sprinkling irrigation system of temperature controlled timing with VHDL language under the MAX+PLUS II. It discusses the design of three modules of system with VHDL. Whole module is completed by the graphic input method of MAX+PLUS II. simulation and a chip testing shows the scheme is reasonable。It's time to design and realize the timing sprinkling irrigation system under temperature control for the first time.
