I摘 要随着社会经济的发展，交通运输越来越发达，汽车行业空前发展，人们出行也越来越多，出行方式由之前的步行、自行车改为出租车，因此加快了出租车行业的发展。城市出租车行业的发展，势必方便人们的出行，增强城市的建设。如何计算顾客乘坐出租车里程费用，需要一款智能的打车计费系统，实现智能化，简洁化，准确化的计算乘客打车金额，因此出租车计价器将具有广阔的市场价值。本设计是一款基于单片机的打开计费系统，主要采用单片机结合外围电路模块来实现计费功能。本系统功能强大，有两种计费方法，分为白天和夜晚两种模式，夜晚价格相对较高。同时支持按时间和里程收费，收费方式灵活。同时采用电机来模拟出租车是否载有乘客。当没乘客乘坐时，液晶屏显示时间和日历，电机不工作。当有乘客乘坐后，液晶界面转到计费界面，电机工作，模拟汽车正常行驶。本系统通过按键来设置各个计费价格，包括起步价，超过起步价后每公里价格，以及白天和夜晚价格，且具有掉电保存功能。计价器关系到乘客的经济利益，在实际生活中很有必要，因此本设计的研究价值很高。关键词：计价器；时钟；单片机IIAbstractWith the development of social economy, transportation is more and more developed, unprecedented development of automobile industry, people travel more and more, the way of travel from the previous walk, bicycle to taxi, so the development of the taxi industry. The development of urban taxi industry is bound to facilitate people's travel and enhance the construction of the city. How to calculate the cost of customers' taxi mileage requires an intelligent taxi billing system, which can realize the intelligent, concise and accurate calculation of passengers' taxi amount. Therefore, the taxi meter will have broad market value.This design is based on a single chip open billing system, the main use of single chip combined with the peripheral circuit module to achieve billing function. This system has powerful functions and two billing methods, which are divided into day and night modes, and the night price is rela...
