基于PROTEUS+AT24C02出租车计价器设计

以AT89C52单片机为核心,完成出租车计价器的设计。采用AT24C02实现在系统掉电时保护,计费显示采用8位8段数码管显示,该设计不仅可以计费,还可以实现白天黑夜的调价,以及中途等待一段时间后总金额的增加,另外设置清零里程按钮用于清零里程和总金额。利用proteus仿真软件模拟出租车计价的功能。

PROTEUS＋AT24C02-based Taximeter Design

With AT89C52 as the core,the article completes the design of taximeter,which realizes the protection of electricity cutting through AT24C02.The billing is displayed through 8-bit 8-section digital tube;the design can not only realize the billing,but also achieve price adjustment at night and daytime,and the rise of total capital after the waiting time.There is also zero clearing mileage button used for zero clearing of mileage and amount.The design also simulates the pricing of taxi through proteus software.
