AbstractWith the development of social economy,transportation is more and more developed,unprecedented development of automobile industry,people travel more and more,the wayof 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 enhancethe construction of the city.How to calculate the cost of customers'taxi mileage requiresan intelligent taxi billing system,which can realize the intelligent,concise and accuratecalculation of passengers'taxi amount.Therefore,the taxi meter will have broad marketvalue.This design is based on a single chip open billing system,the main use of single chipcombined with the peripheral circuit module to achieve billing function.This system haspowerful functions and two billing methods,which are divided into day and night modes,and the night price is relatively high.At the same time support by time and mileagecharges,charges flexible.Electric motors are also used to simulate whether a taxi iscarrying passengers or not.When there are no passengers,the LCD screen displays thetime and calendar,and the motor does not work.When passengers are on board,the LCDinterface turns to the billing interface,and the motor works to simulate the normal runningof the car.The system can set each billing price by pressing the button,including thestarting price,the price per kilometer after exceeding the starting price,and the day andnight price,and has the function of power off and saving.The meter relates to theeconomic interests of passengers,which is necessary in real life,so the research value ofthis design is very high.Key words:meter:clock;SCM
