基于 PLD 的三层电梯的控制设计【摘要】电梯作为现代化的产物在我们的生活之中已必不可少。随着经济建设的高速发展，我国电梯需求量越来越大。由此，一个更为庞大的电梯市场已经在国内轰然形成。本设计是基于可编程逻辑器件（PLD）技术中的甚高速集成电路硬件描述语言（VHDL）语言所开发的三层电梯控制程序。本程序具有 VHDL 语言设计里最为常用的三个模块：实体entity、结构体 architecture、进程执行单元 process。通过程序调试及运行仿真，结果表明，本程序可以完成：电梯运行所在楼层指示、电梯运行方向指示、关门延时设置 、看门狗报警、超载报警、故障报警等。本设计对更高层的电梯控制设计具有一定的拓展性。【关键词】：电梯控制，程序设计，PLD，VHDL ABSTRACTThe product as a modern elevator in our lives has been essential.With the sustained and rapid development of economic construction, China's increasing demand for elevators.As a result, a much larger domestic elevator market has formed a bang. This design is based on Programmable Logic Devices （ PLD ） in a Very High speed of the integrated hardware Describe Language （VHDL） in developing the third floor of the lift of control procedures. this program has vhdl language designed for the best of three modules ： entity, architecture, process. Through the program run, debug and simulation results show that the application can finish：the floor, in the direction, the delay, the guard dog the police, and failure the police, etc. this design with higher the control of the design. 【KEY WORD】:lift control, programmer, PLD, VHDL 目 录引言.......................................................................1一、设计的基础依据.........................................................1（一）EDA 技术介绍......................................................1（二）VHDL 语言介绍.....................................................1（三）MAX+plusII 软件介绍...............................................2二、方案论证...........
