基于FPGA的出租车计费系统的设计
摘要
随着我国市场经济的发展交通也越来越便利特别是计程车以快捷方便的特点早已盛行各个城市成为城市交通的重要工具计程车市场从90年代初的起步阶段到现在已经进入了高峰期随着城市化水平的提高和人民生活水平的改善计程车的服务也就显得越来越重要因此计程车计价器也就应运而生了Design of taxi meter Based on FPGA
Abstract
As Chinas market economy developsmore and more convenient transportparticularly taxis to fast convenient features have long been popular in various cities and become an important tool for urban traffic Taxi market in the early 1990sthe initial stage up to now has entered a peak period With the level of urbanization and the improvement of peoples living standards improve taxi services will become increasingly important Taxi meter therefore it has emerged
This paper analyses the current domestic and foreign taxi billing system and the basic working principle and the two main design Based on the design of microcontroller and FPGA-based design and both the strengths and the ways Shortcomings of the analysiscomparison of the system established after the programme FPGA-based billing system for taxis
In this design mainly through the VHDL language programming billing systems of the four function blocksthe frequency modules control module the measurement modules and decoding modules the final use of PLUSII software to simulate the procedures to Simulation of the realization of a taxi start stop and wait in the course of time and so on including-and billing functionsAnd the results of the functional modules through dynamic decoding scanning module output to display module to display it Through the display module Taxis By the travelling distance a taxi waiting for the time and were waiting for a taxi in the process of moving costs and fees in the process
