基于AT89S51的计费器设计
摘要
单片机具体的专业名词又称为微控制器。于70年代中期创立出来的一种体积小,价格低廉,功能又很强大的大规模集成电路器件。计价器的出现可以随时计算人们该次行程应该支付的费用并以直观的方式通过液晶显示屏显示出来,得到解决司机和乘客都认可的车费支付问题的方案。在很多的国家,单片机技术无声无息的进入了每个人的生活中。尤其是在我国,各种工业控制、航空技术、仪表、家用电器等等都装有着单片机。所以单片机无疑是所有先进科技和人们生活中必不可少的一份子。
本课题主要研究出租车计费器的软、硬件设计,选择AT89S51单片机为核心,选择A44E霍尔传感器将车辆行驶距离转换成信号输入单片机,采用1602作为结果显示部件,显示当前时间、行车里程、等待时间、应支付金额等信息。
