Taximeter is the transaction criteria between the passengers and drivers, it is an important symbol of the taxi industry, and taximeter is also the most important part of the taxi. It relates to the benefits interests of both drivers and passengers. Has a good performance regardless of the meter are very necessary to a vast. Therefore, the car meter is also of much research value.
The paper is about a taximeter，Which mainly contains AT89C51 controller,7279 output module, LED displaying module, key module, input module. The display controlling sum fore-end mileage measurement and LED numerical code by the fact that the monolithic machine carries out a programming combines each other .the main function is to realize calculation and display pushing down to the total price, mileage and latency time. Adopt the design that the monolithic machine to carries out ,It's relatively powerful, using less hardware and appropriate software mutual coordination to be able to design that call for. The flexibility is strong, and it can make many functions through the software programming.
