停车场仿真程序仿真原理：首先有两个定时器自动的随机产生请求入场的卡号和请求出场的卡号，然后剩余的事件都由处理场务事件来处理了。处理场务事件相当于一个车场总指挥。当他发现有卡号请求入场时他会决定该卡是否符合入场条件，如果不符合，直接丢掉该卡号，准备处理下一个卡号。否则看车库是否已满和车库过道是否空闲，如果车位没有满且过道是空的，则允许该车入场，并在此时将车场的最左面的空车位分给他使用。剩下的事就是让车通过过道和进入车位，并及时关闭车场入口。如果过道是空的而且又没有入场请求，则处理出场请求，首先是将车辆从车位上移到过道上，并向出口行驶，然后在出口出判断卡是否符合出场条件，如果符合则发出抬出场杆命令，允许其出场。否则让该车返回车位。程序运行时会写运行日志，在阅读本文后，相信能理解运行日志的内容-err
