1 三层电梯控制器将实现的功能

(1)每层电梯入口处设有上下请求开关，电梯内设有顾客到达层次的停站请求开关。

(2)设有电梯入口处位置指示装置及电梯运行模式(上升或下降)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，开门指示灯亮，开门4秒后，电梯门关闭(开门指示灯灭)，电梯继续进行，直至执行完最后一个请求信号后停留在当前层。

(5)能记忆电梯内外所有请求，并按照电梯运行规则按顺序响应，每个请求信号保留至执行后消除。

(6)电梯运行规则一当电梯处于上升模式时，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，则直接升到由下楼请求的最高层，然后进入下降模式。当电梯处于下降模式时则与上升模式相反。

(7)电梯初始状态为一层开门状态。

-A three-lift controller functions to be achieved

　　(1) the entrance of each floor with elevator up and down the request switch, the elevator is equipped with customer requests to reach levels stop switch.

　　(2) with elevator entrance and elevator position indicator device operation mode (up or down) installation instructions.

　　(3) elevators per liter (lower) floor.

　　(4) The elevator reaches a floor request stops after 1 second elevator door open, open indicator light, open 4 seconds, the elevator doors closed

(Open LED OFF), the lift continued until the implementation of the complete signal after the last request to stay in the current layer.

　　(5) can remember all requests inside and outside the elevator and elevator operation in accordance with the rules in order to respond to each request signal to be retained until after the implementation of consumer

In addition.

　　(6) the operating rules of an elevator when the elevator is up mode, the only response to the h
