Abstract
It’s a multi-functional taxi pricing system, which takes single chip microcomputer AT89C51 as the core, using peripherals such as hall sensor A44E, clock chip DS1302, keyboard display module and overspeed alarm module.This paper introduces the main program flow,the hardware circuit, as well as the software program .It also elaborates on the key technical points of hardware and software involved in the pricing system design process.A simulation is run to debug the software development
environment, which is a integration of Proteus and Keil c51.The simulation result shows a variety of measurement functions of the pricing system, combining mileage calculating with timing, billing, etc. In addition to the above,this pricing system also possesses the overspeed alarm function compared with the existing systems.
