According to the predeterm
3、ined design requirements and design ideas, this paper uses the platform of MAX + PLUS software and VHDL hardware description language to design a taximeter system. This paper mainly introduces the structure of the system and circuit design, it not only to achieve, bill, preset and simulate the start
4、, stop, pause and other functions of car, but also to scan the showed fare number dynamically. Through the experimental simulation, it can get the results of the design and the simulation wareform by maxplus softwave. By the analysis of software simulation waveform and the hardware debugging results,it shows that the system can achieve the basic functions of taximeter, such as simulate the bill and so on. If it can be further improved in other areas, marketization will be true to a certai
