1、___________________________________________________________________________________________________公交车新型智能选站报站系统摘要现今各个城市、城镇的公交车越来越多,所以他们需要一个比较好的公交车选站报站系统。现有的公交车报站系统在报站功能上已经做得很完善,但他们依然还有许多不完善的地方。例如乘客要下车的时候认识路的就按按钮,而那些不知道路的只有问司机了,如果每个站都问司机,不仅乘客觉得麻烦。而且司机也感到麻烦。这样就对安全构成了危险。对于司机来说,也没有办法知
2、道乘客需要在那些站点下车,只能每站必停,有些站点本来可以不用停车,但是因为不了解情况,也必须停车了,从而浪费不必要的时间和汽油。这样是不好的。为了克服这些不好的缺点,我们从增强乘客和司机的互动性出发,增加了选站功能,从而构成这个新型智能选站报站系统。它使用现今比较流行的单片机还有语音芯片等而设计成的。本文就是讲述怎样把单片机与语音芯片等很好的有机的结合的。关键词:单片机语音芯片LED蜂鸣器按钮AbstractNowadayseachcity,thecitiespublictransportationvehiclemoreandmorearemany,ther
