基于VHDL三层电梯控制器的设计

Based on VHDL three-lift controller design

用层次化的设计方法,通过硬件描述语言VHDL对电梯控制器各功能模块进行编程,并使用MAX+PLUSⅡ软件对该程序进行了编译、仿真,结果表明该电梯遵循方向优先的原则提供三个楼层多用户的载客服务并指示电梯的运行情况。

Through the hierarchical design methods, function modules of the lift controller are programed by VHSIC Hardware Description Language （VHDL）, then use MAX ＋ PLUS Ⅱ to compile and simulate the programe. The result indicates that the lift can provide three stories, multiuser passenger carrying service and display operating status at the same time according to the dirction priority principle.
