7、能力，培养自身建立正确的设计思想，掌握课程设计的一般程序、规范和方法。力。１.３　控制要求a)电梯位置及运行方向的确定与显示。能在电梯轿厢内外显示电梯当前所在楼层位置和运行方向。（即应有楼层数字显示和运行方向显示）b)轿厢内的指令选层及门厅的外唤信号。轿厢内乘客可按下轿厢内的选层按钮选定所需到达的目的楼层（内选信号）；门厅乘客可按下门厅的上、下行召唤按钮进行上、下召唤（外唤信号）。内选和外唤信号均应被记忆并有指示灯点亮指示，并在得到满足时应能自动消除。a)电梯自动运行时的信号响应。电梯在运行过程中，只响应同方向的呼唤要求，而不响应中途反向呼唤要求，当到达本

8、方向的最远的内选、外唤楼层后才开始返回，但反向呼唤应作登记。但如果
