[单片机开发] dianti

模拟某校九层教学楼的电梯系统。该楼有一个自动电梯,能在每层停留。九个楼层由下至上依次称为地下一层、第一层、第二层、……第八层,其中第一层是大楼的进出层,即是电梯的“本垒层”,电梯“空闲”时,将来到该层候命。 乘客可随时地进出于任何层。对于每个人来说,他有一个能容忍的最长等待时间,一旦等候电梯时间过长,他将放弃。 模拟时钟从0开始,时间单位为0.1秒。人和电梯的各种动作均要消耗一定的时间单位(简记为t),比如:有人进出时,电梯每隔40t检测一次,若无人进出,则关门;关门和开门各需要20t;每个人进出电梯均需要25t;如果电梯在某层精致时间超过300t,则驶回1层候命
