9、uk it planing w ork ne w iea该系统利用VHDL语言、PLD设计出租车计费系统，以 MAX+PLUS n软件作为开发平台，设计了 出租车计费器系统程序并进行了程序仿真。使其实现计费以及预置和模拟汽车启动、停止、暂停等 功能，并动态扫描显示车费数目。关键词：出租车计费器；计数器； VHDL语言；MAX+PLUS II ;一、实验任务及要求1 .能实现计费功能，计费标准为：按行驶里程收费，起步费为10.00元，并在车行3公里后再按2元/公里，当计费器计费达到或超过一定收费 (如20元)时，每公里加收50%的车费，车停止不计 费。2 .实现预置功能：能预置起步费、每公里收费

10、、车行加费里程。3 .实现模拟功能：能模拟汽车启动、停止、暂停、车速等状态。4 .设计动态扫描电路：将车费显示出来，有两位小数。5 .用VHDL语言设计符合上述功能要求的出租车计费器，并用层次化设计方法设计该电路。6 .各计数器的计数状态用功能仿真的方法验证，并通过有关波形确认电路设计是否正确。7 .完成电路全部设计后，通过系统实验箱下载验证设计的正确性。二、实验原理系统顶层框图：计费器按里程收费，每 100米开始一次计费。各模块功能如下：(1)车速控制模块当起停键为启动状态时(高电平)，模块根据车速选择和基本车速发出响应频率的脉冲驱动计费 器和里程显示模块进行计数；当处于停止状态时暂停发出脉

11、冲，此时计费器和里程显示模块相应的 停止计数。(2)卜程动态显小模夬yuan, a n incease of 75% lo - gve nment ge nea budget revenue of milon Yuan, - Panlng,m.e _lur ceates new Ma Cuch commuh, c .g Like nic spot _l ue idual on ba se, re. ei hgh eva uatinfrom provinca and muicpa d ” ie Inspect ."mm peoplesSpecaeport. "Sa, pr i
