Description: 设计一个6层电梯控制器。电梯控制器是按照乘客的要求自动上、下的装置。
1、每层电梯入口处设置上下请求开关，电梯内设有顾客到达层次的停站请求开关。
2、设有电梯所处位置指示装置以及电梯运行模式（上升或者下降）指示装置。
3、电梯每秒升降一层楼。
4、电梯到达有停站请求的楼层，经过1秒电梯门打开，开门4秒后，电梯门关闭（开门指示灯灭），电梯继续运行，直至执行完最后一个请求信号后停留在当前层。
5、电梯能记忆电梯内外所有请求信号，并按照电梯运行规则按顺序响应，每个请求信号保留至有电梯响应后消除。
6、初始状态为一层开门，第一层不用向下开关，最高层不用向上开关。
7、电梯运行规则：当电梯上升时，只响应比电梯所在位置高的上楼请求信号，由下而上逐个执行，直到最后一个上楼请求执行完毕；如果高层有下楼请求，则直接升到下楼请求的最高楼层，然后进入下降模式。当电梯处于下降模式时与上升正好相反。

Description: 高楼电梯自动控制系统(Windows平台上运行的ispLEVER编程软件。
):
1统控制的电梯往返于1-9层楼。
2客要去的楼层数可手动输入并显示（设为A数）。
3梯运行的楼层数可自动显示（设为B数）。
4A>B时，系统能输出使三相电机正转的时序信号，使电梯上升；
当A<B时，系统能输出使三相电机反转的时序信号，使电梯下降；
当A=B时，系统能输出使三相电机停机的信号，使电梯停止运行并开门；
5是上升还是下降各层电梯门外应有指示，各层电梯门外应有使电梯上升或下降到乘客所在楼层的控制开关。
注：此为word文档，但里面有源代码。-High-rise elevator control system (Windows platform programming software running on the ispLEVER.

An elevator control system and from 1-9 floors.
2, the number of passengers going to the floor can manually enter and display (Make A number).
3 ladder run automatically display the number of floors (Set B number).
4A> B, the system can output three-phase motor is transferred to the timing signal to lift up
When A <B, the system can output three-phase motor to reverse the timing signal to the lift down
When A = B, the system can output a signal to shut down three-phase motor, so that the lift stops and open the door
5 is increasing or decreasing the lift on each floor outside the door should be directed, due to lift on each floor outside the elevator up or down to the floor where the passenger control switch.
